Abstract The purpose of this study was to predict the total phenolic content (TPC) and total flavonoid content (TFC) in several horticultural commodities using near-infrared spectroscopy (NIRS) combined with machine learning. Although models are typically developed for a single product, expanding the coverage of the model can improve efficiency. In this study, 700 samples were used, including varieties of shallot, cayenne pepper, and red chili. The results showed that the TPC model developed yielded R 2cal, root mean squares error in the calibration set, R 2pred, root mean squares error in prediction set, and ratio of performance to deviation values of 0.79, 123.33, 0.78, 124.20, and 2.13, respectively. Meanwhile, the TFC model produced values of 0.71, 44.52, 0.72, 42.10, and 1.87, respectively. The wavelengths 912, 939, and 942 nm are closely related to phenolic compounds and flavonoids. The accuracy of the model in this study produced satisfactory results. Therefore, the application of NIRS and machine learning to horticultural products has a high potential of replacing conventional laboratory analysis TPC and TFC.
摘要本研究的目的是利用近红外光谱(NIRS)和机器学习相结合的方法预测几种园艺商品中的总酚含量(TPC)和总黄酮含量(TFC)。尽管模型通常是为单个产品开发的,但扩大模型的覆盖范围可以提高效率。在这项研究中,使用了700个样本,包括各种葱、辣椒和红辣椒。结果表明,所开发的TPC模型产生的校正集均方根误差R2cal、预测集中均方根误差R2 pred和性能与偏差值之比分别为0.79、123.33、0.78、124.20和2.13。同时,TFC模型产生的值分别为0.71、44.52、0.72、42.10和1.87。波长912、939和942 nm与酚类化合物和黄酮类化合物密切相关。本研究中模型的准确性产生了令人满意的结果。因此,近红外光谱和机器学习在园艺产品中的应用具有取代传统实验室分析TPC和TFC的巨大潜力。

Abstract The world population is expected to double by 2050, creating a greater demand for animal protein sources. This calls for an increase in the supply of animal-derived foods in order to avoid food scarcity in the future. Non-ruminants, which would have been a panacea to this increased demand for animal-derived foods, have suffered from the rising costs of feed ingredient world-wide. The increase in the prices of conventional feedstuffs have attracted the attention of researchers on the potentials of lesser-known tropical medicinal plants like Dialium guineense Willd (black velvet tamarind) as a feed resource for non-ruminants. The increase in prices of conventional feedstuffs have attracted the attention of researchers on the potentials of lesser-known tropical medicinal plants. One such lesser-known tropical plant that can be used in chicken and livestock production is black velvet tamarind. The plant is found in many parts of the world. It belongs to the family Fabaceae, has high forage yield, resistant to drought and insects, and does not require annual cultivation. The whole seed is moderate in crude protein and fibre but high in carbohydrates. The leaf, on the other hand, is low in carbohydrate, moderate in crude protein, and high in ash. D. guineense stem bark and fruit are excellent source of essential oils, and rich source of dietary fibre, minerals, and vitamins for monogastrics. The plant is endowed with beneficial phytochemicals such as alkaloids, tannins, phenols, flavonoids which may serve as natural alternatives to in-feed antibiotics. D. guineense has beneficial pharmacological effects including antioxidant and antimicrobial properties. The purpose of this study was to review the body of knowledge on the nutritional and chemical composition of D. guineense and its impact in animal production.
摘要到2050年,世界人口预计将翻一番,对动物蛋白质来源的需求将更大。这就要求增加动物源性食品的供应,以避免未来食品短缺。非反刍动物本可以成为应对动物源性食品需求增加的灵丹妙药,但由于全球饲料成分成本的上涨,它们受到了影响。传统饲料价格的上涨引起了研究人员对Diallium guinense Willd(黑绒罗望子)等鲜为人知的热带药用植物作为非反刍动物饲料资源的潜力的关注。传统饲料价格的上涨引起了研究人员对鲜为人知的热带药用植物潜力的关注。黑丝绒罗望子是一种鲜为人知的热带植物,可以用于鸡肉和牲畜生产。这种植物在世界许多地方都有。它属于蚕豆科,饲草产量高,耐旱防虫,不需要每年栽培。整个种子的粗蛋白质和纤维含量适中,但碳水化合物含量高。另一方面,叶子碳水化合物含量低,粗蛋白含量适中,灰分含量高。D.guinense茎皮和果实是精油的极好来源,也是单胃药膳食纤维、矿物质和维生素的丰富来源。该植物富含有益的植物化学物质,如生物碱、单宁、酚类和黄酮类化合物,可作为饲料中抗生素的天然替代品。D.guinense具有有益的药理作用,包括抗氧化和抗菌特性。本研究的目的是回顾有关D.guinense的营养和化学成分及其在动物生产中的影响的知识体系。

Abstract All birds produce vocalizations as a form of tcommunication with other individuals. Different from songbirds, crowing is a singing vocalization produced by chickens that cannot be learned through imitation. Some genes are assumed to be responsible for this activity. The long-crowing chickens have a melodious and long sound, so they are categorized as singing chickens. They are part of the biodiversity in Indonesia, which has high economic and socio-cultural value. Reviews about long-crowing chickens, especially in Indonesia, are still very rare. This article aims to identify the uniqueness and the existence of long-crowing chickens, together with the conservation efforts needed to manage them. Information was collected from journal articles and other relevant documents. There are four local chickens in Indonesia classified as long-crowing chickens. They are developed in different areas of the community with different socio-cultural characteristics. The fundamental differences among the breeds that can be quantified are in crowing duration and the number of syllables. The government has acknowledged that long-crowing chickens are important genetic resources; however, the association and individual keepers or enthusiasts are vital actors in conservation efforts. The information about long-crowing chickens in Indonesia is incomplete. The research activities that need to be conducted include exploring the population number and distribution, as well as documentation of the local knowledge of chicken breeders and enthusiasts.
摘要所有鸟类都会发出叫声,作为与其他个体交流的一种形式。与鸣禽不同,啼叫是鸡发出的歌唱声,不能通过模仿来学习。一些基因被认为对这种活动负责。长鸣鸡的叫声悠扬而绵长,所以它们被归类为鸣鸡。它们是印度尼西亚生物多样性的一部分,具有很高的经济和社会文化价值。关于长鸣鸡的评论,尤其是在印度尼西亚,仍然非常罕见。本文旨在确定长鸣鸡的独特性和存在性,以及管理它们所需的保护工作。信息是从期刊文章和其他相关文件中收集的。印尼有四只土鸡被归类为长鸣鸡。它们是在社区的不同地区发展起来的,具有不同的社会文化特征。可以量化的品种之间的根本差异在于鸣叫持续时间和音节数量。政府已经承认,长期鸣叫的鸡是重要的遗传资源;然而,该协会和个体饲养员或爱好者是保护工作的重要参与者。关于印尼长时间鸡鸣的信息是不完整的。需要进行的研究活动包括探索种群数量和分布,以及记录养鸡者和爱好者的当地知识。

Abstract Genotype assessment across various environments is a basic condition for developing stable and superior genotypes for sustainable maize production in the South-East of the DR Congo. Therefore, this research’s objectives were to identify the performance of newly developed provitamin A maize genotypes in various environments, and to recommend high-performing and stable genotypes for broader adaptation. Eight provitamin A maize genotypes, including one commercial variety, were planted at three sites during two consecutive cropping seasons (2020/2021 and 2021/2022) forming six environments. All genotypes in six environments were planted in a randomized complete block design containing three replications. Two stability analysis approaches, GGE biplot and Eberhart and Russell method are widely used to identify high yielding and stable genotypes. The combined analysis of variance revealed that G and E as well as their interaction (GEI) have significantly affected the emergence rate, cob’s insertion height, days to anthesis and silking, cob length, cob grain weight and grain yield. Average grain yield varied from 8.30 t/ha for PVAH-7L to 9.41 t/ha for PVAH-1L. The Eberhart and Russell method and the CV identified PVAH-1L, PVAH-4L, PVAH-7L and PVAH-6L as the most stable genotypes, but could not reliably identify the high yielding genotypes. On the other hand, the GGE biplot reliably and graphically showed the stable and high-yielding genotypes (PVAH-1L > PVAH-6L) as well as the low-yielding genotypes (PVAH-7 > PVAH-4L). In additional, the GGE biplot showed that L’shi21 was the best test environment for selecting high performing and stable provitamin A maize genotype. The results of this study indicate that PVAH-1L and PVAH-6L are the stable, high-yielding provitamin A maize genotypes in the South-East of the Democratic Republic of the Congo and should be disseminated in this region.
不同环境下的基因型评估是为刚果民主共和国东南部玉米可持续生产开发稳定和优质基因型的基本条件。因此,本研究的目的是确定新开发的维生素A原玉米基因型在不同环境下的性能,并为更广泛的适应推荐高性能和稳定的基因型。包括一个商业品种在内的8种维生素A原玉米基因型,在连续两个种植季节(2020/2021和2021/2022)的3个地点种植,形成6个环境。所有基因型在6个环境中种植,采用随机完全区组设计,包含3个重复。两种稳定性分析方法,GGE双图和Eberhart和Russell方法被广泛用于鉴定高产和稳定的基因型。综合方差分析表明,G和E及其互作(GEI)显著影响出苗率、穗轴插高、花期和出丝期、穗轴长、穗轴粒重和籽粒产量。pah - 7l的平均产量为8.30 t/公顷,pah - 1l的平均产量为9.41 t/公顷。Eberhart and Russell法和CV法鉴定出PVAH-1L、PVAH-4L、PVAH-7L和PVAH-6L是最稳定的基因型,但不能可靠地鉴定出高产基因型。另一方面,GGE双图可靠且图形化地显示了稳定高产基因型(PVAH-1L > PVAH-6L)和低产基因型(pvah - 7> PVAH-4L)。此外,GGE双图显示L’shi21是筛选高效稳定的维生素A原玉米基因型的最佳试验环境。本研究结果表明,PVAH-1L和PVAH-6L是刚果民主共和国东南部稳定高产的维生素A原玉米基因型,应在该地区推广。

Abstract The objective of the study was to assess the effect of varying levels of water deprivation on growth performance, carcass characteristics, and internal organ weight of broiler chickens. Ninety unsexed Ross 308 chicks 2 weeks old were randomly assigned to five water deprivation periods of 0, 6, 12, 18, and 24 h. Each treatment was replicated three times with six birds per replicate. Broiler chickens were given water ad libitum (0 h) or for 30 min at 6-, 12-, 18-, and 24-h intervals. Average daily feed intake (ADFI), average daily gain (ADG), and feed conversion ratio (FCR) were determined on a weekly basis. A negative linear relationship (P < 0.05) existed between water deprivation and ADFI. The increase in water deprivation level resulted in ADFI decreasing at an increasing rate. The R 2 value was 0.94. There was no relationship between water deprivation on ADG and FCR (P > 0.05). There was a quadratic relationship between water deprivation and cold dress mass (CDM) and warm dress mass. As the level of water deprivation increased, there were linear increases in relative weight of gizzard, spleen, heart, lungs, liver, and gastrointestinal tract (P < 0.001). The organ weights of the broiler chickens revealed the ability of birds to withstand of up to 24 h. Using differential of quadratic equations, the maximum time of water deprivation that did not negatively affect CDM was estimated to be 4 h.
摘要本研究的目的是评估不同程度的水分剥夺对肉鸡生长性能、胴体特性和内脏重量的影响。90只2周大的未交配Ross 308雏鸡被随机分配到5个缺水期,即0、6、12、18和24 h.每个处理重复三次,每次重复六只鸟。肉鸡随意饮水(0 h) 或30 以6、12、18和24小时为一次。每周测定平均日采食量(ADFI)、平均日增重(ADG)和饲料转化率(FCR)。缺水与ADFI呈负相关(P<0.05)。缺水水平的增加导致ADFI以增加的速度下降。R2值为0.94。水分剥夺对ADG和FCR的影响无统计学意义(P>0.05),水分剥夺与冷量和暖量呈二次关系,随着水分剥夺程度的增加,肉鸡的器官重量显示其耐受能力高达24小时。使用二次方程的微分方程,估计对CDM没有负面影响的最长缺水时间为4小时 h。

Abstract The diverse sources of agricultural extension information do not guarantee increased farmers’ capabilities to adopt agricultural innovations. Consequently, efforts to accelerate the adoption of agricultural innovations should pay particular attention to farmers’ compatibility with different information sources. This study aims to analyze farmers’ perceptions of various information sources about rice commodity innovations and determine the information sources influencing farmers’ capabilities in adopting rice innovations. The study was conducted from June to December 2019 through a structured survey approach with 270 rice farmers in Subang, West Java and Boyolali, Central Java, Indonesia, by using structural equation model analysis. The results showed that rice farmers had positive perceptions of government, private, and self-subsistent extension. The capability level of rice farmers showed that all indicators were significantly different. Farmers could improve their capabilities and sustainability of rice farming by adopting agricultural innovations. Information from government and private extension providers had a positive effect on the capacity and capability of rice farmers. The role of self-subsistent extension was more of a facilitator and did not directly affect the capacity and capability of farmers. Participatory extension activities are recommended as a form of intervention that can improve rice farmers’ capacity and capability in terms of technology adoption processes. The extension activities should be provided as a series, rather than one-off events, so that farmer knowledge accumulates over time through a style and pace to match their skills and level of education.
摘要农业推广信息来源的多样性并不能保证提高农民采用农业创新的能力。因此,加快采用农业创新的努力应特别注意农民与不同信息来源的兼容性。本研究旨在分析农民对水稻商品创新的各种信息来源的看法,并确定影响农民采用水稻创新能力的信息来源。该研究于2019年6月至12月通过结构方程模型分析,对印度尼西亚西爪哇苏邦和中爪哇博约拉里的270名稻农进行了结构化调查。结果表明,稻农对政府、私人和自给自足的延伸有积极的认知。稻农的能力水平表明,各项指标差异显著。农民可以通过采用农业创新来提高他们的水稻种植能力和可持续性。政府和私营推广机构提供的信息对稻农的能力和能力产生了积极影响。自给自足的推广的作用更多的是一种促进者,并没有直接影响农民的能力和能力。建议将参与性推广活动作为一种干预形式,以提高稻农在技术采用过程方面的能力。推广活动应作为一系列活动提供,而不是一次性活动,以便农民的知识通过与他们的技能和教育水平相匹配的方式和速度随着时间的推移而积累。

This study aims to analyze farmers’ perceptions of various information sources about rice commodity innovations and determine the information sources influencing farmers’ capabilities in adopting rice innovations. The study was conducted from June to December 2019 through a structured survey approach with 270 rice farmers in Subang, West Java and Boyolali, Central Java, Indonesia, by using structural equation model analysis. The results showed that rice farmers had positive perceptions of government, private, and self-subsistent extension. The capability level of rice farmers showed that all indicators were significantly different. Farmers could improve their capabilities and sustainability of rice farming by adopting agricultural innovations. Information from government and private extension providers had a positive effect on the capacity and capability of rice farmers. The role of self-subsistent extension was more of a facilitator and did not directly affect the capacity and capability of farmers. Participatory extension activities are recommended as a form of intervention that can improve rice farmers’ capacity and capability in terms of technology adoption processes. The extension activities should be provided as a series, rather than one-off events, so that farmer knowledge accumulates over time through a style and pace to match their skills and level of education.","PeriodicalId":45740,"journal":{"name":"Open Agriculture","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44474749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abstract The abundance of agricultural products often causes environmental problems. The utilization of agricultural waste from carrots can reduce both the feed cost and environmental pollution and become a source of vitamin A for the health of the native chicken. The study aims to analyze carrot (Daucus carota L.) waste juice on native chicken performance. It was conducted from April to July 2019 at Pandu experimental field in North Minahasa Regency. The practical method used was a completely randomized design with four replications. The experimental livestock used in the study was 80-day-old chickens of native chicken. The concentration of carrot juice during the study was as follows: 100% drinking water without carrot juice (W0), 80% water drinking + 20% carrot juice (W1), 60% drinking water + 40% carrot juice (W2), and 20% drinking water + 80% carrot juice (W3). Observed variables included feed intake, body weight gain, feed conversion ratio (FCR), and mortality rate. The results showed that carrot waste juice significantly impacted the body weight gain, feed conversion rate, and 0% mortality rate during the 8 weeks. The concentration of 20% drinking water + 80% carrot juice (W3) with the feed intake ratio of 1.608 g, body weight gain value of 775.63 ± 301  g, and the FCR of 2.1 ± 0.06. However, the consumption ratio did not differ among treatments. The addition of carrot waste juice, as much as 80%, in the drinking water of native chickens showed an increase in body weight compared to other treatments. In conclusion, the current study showed that treatment of carrot waste juice has a significant effect on body weight in 8 weeks of maintenance. Meanwhile, the feed intake ratio of carrot waste juice treatment has no real effect. There was no dead chicken (0%) in the present study. The carrot waste juice can be used in chicken drinks 40–80% by paying attention to the balance of energy content and feed proteins used to grow chickens.
摘要丰富的农产品往往引起环境问题。胡萝卜农业废弃物的利用可以降低饲料成本和环境污染,并成为土鸡健康维生素a的来源。本研究旨在分析胡萝卜(Daucus carota L.)废汁对土鸡生产性能的影响。该研究于2019年4月至7月在北米纳哈萨县的Pandu试验田进行。实际使用的方法是完全随机设计,有4个重复。本研究的实验家畜为80日龄土鸡。研究期间胡萝卜汁的浓度为:100%不含胡萝卜汁的饮用水(W0)、80%饮用水+ 20%胡萝卜汁(W1)、60%饮用水+ 40%胡萝卜汁(W2)、20%饮用水+ 80%胡萝卜汁(W3)。观察变量包括采食量、增重、饲料系数和死亡率。结果表明:8周内,胡萝卜废汁对肉鸡增重、饲料转化率和0%死亡率均有显著影响。20%饮用水+ 80%胡萝卜汁(W3)浓度,采食量为1.608 g,增重值为775.63±301 g,料重比为2.1±0.06。然而,不同处理之间的消耗比率没有差异。在土鸡的饮用水中添加80%的胡萝卜废汁,与其他处理相比,体重有所增加。综上所述,本研究表明,胡萝卜废汁处理对维持8周的体重有显著影响。同时,胡萝卜废汁处理对采食量比无实际影响。本试验无死鸡(0%)。胡萝卜废汁在鸡饮品中的利用率可达40-80%,需注意养鸡所用能量含量与饲料蛋白质的平衡。

Abstract This research aimed to formulate priority strategies for adopting Internet of Things (IoT)-based innovation by millennial farmers in Central Java Province, Indonesia. This research uses quantitative methods. The two stages involved were exploring external factors using a political, economic, social, and technological approach and internal factors using the resource-based view approach including human resources, physical resources, and organizational resources. Interviews were conducted with 120 millennial farmers in ten regions of Central Java. This led to the formulation of alternative adoption strategies. Furthermore, the second stage was formulating strategic priorities using the analytical network process approach, involving purposively selected experts from policymakers in the government. According to the research, the most considered factors for IoT adoption strategies were relative advantage, social influence, and technology anxiety. In the relative advantage, the most prioritized sub-factor was business profit. The most prioritized technology anxiety sub-factor cluster was unfamiliar with using IoT. The most prioritized social influence sub-factor cluster was a personal relationship. The resulting strategic priorities were strengthening openness to change, IoT education to millennial farmers, optimizing the role of institutions, and socializing the benefits of IoT to millennial farmers. Openness to change motivates millennial farmers to achieve continuous and better innovation. Millennial farmers need to be prepared for the new experiences to come. Government support through education, intensive mentoring, and increasing the active role of farmer mentoring institutions accelerates the adoption of IoT by millennial farmers.
摘要本研究旨在制定印尼中爪哇省千禧一代农民采用基于物联网(IoT)的创新的优先战略。本研究采用定量方法。所涉及的两个阶段是使用政治、经济、社会和技术方法探索外部因素,以及使用基于资源的观点方法探索内部因素,包括人力资源、物质资源和组织资源。对中爪哇十个地区的120名千禧一代农民进行了采访。这导致制定了替代收养战略。此外,第二阶段是利用分析网络过程方法制定战略优先事项,有针对性地从政府决策者中挑选专家。根据研究,物联网采用策略最受考虑的因素是相对优势、社会影响和技术焦虑。在相对优势中,最优先考虑的子因素是商业利润。最优先考虑的技术焦虑子因素集群不熟悉使用物联网。最优先考虑的社会影响子因素集群是个人关系。由此产生的战略优先事项是加强对变革的开放性,对千禧一代农民进行物联网教育,优化机构的作用,并将物联网的好处社会化给千禧一代的农民。对变革的开放性促使千禧一代农民实现持续和更好的创新。千禧一代的农民需要为即将到来的新体验做好准备。政府通过教育、强化辅导和加强农民辅导机构的积极作用提供支持,加速了千禧一代农民对物联网的采用。

Abstract Recently, capacity building has been named the government’s target in evaluating strengthening land function cycle collaboration in reducing disaster conflicts due to palm oil expansion. Disaster conflicts over palm oil plantations are the main cause of the fundamental transition of environmental culture and customs, especially concerning the welfare capacity of indigenous people in Jambi Province, Indonesia. This article aims to combine information on decision hierarchies and Geographical Information System (GIS) imaging applications to assess complaints of disaster risk in the development of palm oil clusters on indigenous welfare factors due to the palm oil boom in eight Rokan hamlets, Jambi. The combination of the Analytical Hierarchy Process simulation and GIS method in the GeoDa density test is used synergistically to analyze the following criteria for disaster causes: land disputes, water pollution, habitat scarcity, drought/forest fires, floods, and crop failure. The results of the disaster hierarchy show that the priority criteria are land disputes followed by drought/forest fires and floods. Meanwhile, the answer to alternative stakeholder decisions is the regional government according to predictions from the findings of the frequency of resolution of conflicts that have occurred in the past. In addition, the GIS density results detected six Rokan hamlets in Jambi having very high and high conflicts, but two hamlets had no disaster conflict incidents. A capacity building approach in the social, economic, and environmental fields is one of the solutions in minimizing land conflicts caused by palm oil expansion.
最近,在评估加强土地功能循环协作以减少棕榈油扩张引发的灾害冲突时,能力建设被列为政府的目标。棕榈油种植园的灾害冲突是环境文化和习俗发生根本性转变的主要原因,特别是涉及到印度尼西亚占比省土著人民的福利能力。本文旨在结合决策层次和地理信息系统(GIS)成像应用的信息,评估棕榈油集群发展中对土著福利因素的灾害风险投诉,这是由于占比的八个Rokan村庄的棕榈油繁荣。在GeoDa密度测试中,将层次分析法模拟与GIS方法相结合,协同分析以下灾害原因标准:土地纠纷、水污染、栖息地稀缺、干旱/森林火灾、洪水和作物歉收。灾害等级的结果表明,优先级标准是土地纠纷,其次是干旱/森林火灾和洪水。与此同时,根据对过去发生的冲突解决频率的研究结果的预测,替代利益相关者决策的答案是地区政府。此外,GIS密度结果发现占比的6个罗坎村存在非常高和高度冲突,但2个村庄没有发生灾害冲突事件。在社会、经济和环境领域进行能力建设是减少棕榈油扩张引起的土地冲突的解决方案之一。

Abstract This study was aimed (1) to analyze the productivity, cost, and income of potato farming; (2) to analyze the risk of potato farming; and (3) to analyze the potato trade system at the level before and during COVID-19 pandemic. This study used a descriptive-quantitative research type. It was conducted in Banjarnegara Regency, Jawa Tengah Province, Indonesia. The data were collected through surveys, observations, and Focus Group Discussions. The unit of analysis is the farmers who plant potatoes. Data analysis was done descriptively. The results showed that there is no difference between the two marketing channels before and during pandemic. There are two channels of the trading system, namely farmer–collector–traders–wholesaler–exporter partners and farmer–collector–traders–wholesalers–retailers. However, the trading model maximizes the Agribusiness Sub Terminal (AST) as a potato trading agent that can provide direct price information, attract traders, and facilitate transactions and trading contacts. The trading model allows potato trading agents to provide direct price information, attract traders, and facilitate transactions and trading contacts. The implication of this study is to anticipate productivity risk and potato farming income risk through the AST function. This study contributes to the condition of farming before and during COVID-19 pandemic by comparing differences in productivity, costs, income, productivity risk, and income risk as well as the potato grading model.
摘要本研究旨在(1)分析马铃薯种植的生产力、成本和收入;(2) 分析马铃薯种植的风险;(3)分析新冠肺炎大流行前和大流行期间的马铃薯贸易体系。本研究采用描述性定量研究的方法。它是在印度尼西亚爪哇登加省的Bangarnegara县进行的。数据是通过调查、观察和焦点小组讨论收集的。分析单位是种植土豆的农民。数据分析是描述性的。结果表明,疫情前和疫情期间,这两种营销渠道没有差异。贸易体系有两个渠道,即农民-收集者-贸易商-批发商-出口商合作伙伴和农民-收藏者-贸易商–批发商-零售商。然而,该交易模式最大限度地利用农业综合企业子终端(AST)作为土豆交易代理,可以提供直接的价格信息,吸引贸易商,并促进交易和交易联系。该交易模式允许土豆交易代理提供直接的价格信息,吸引贸易商,并为交易和交易联系提供便利。本研究的意义在于通过AST函数预测生产力风险和马铃薯种植收入风险。这项研究通过比较生产力、成本、收入、生产力风险和收入风险的差异以及马铃薯分级模型,有助于了解新冠肺炎大流行之前和期间的农业状况。
