Abstract Soil nutrients can be reduced because of global climate change. This is because climate change causes high rainfall intensity and a prolonged dry season. Efforts to overcome this are fertilized using bioameliorants so that soil nutrients remain available for plants. Observations have been made from May to August 2018 at the JAMTANI Field Laboratory. The study used a factorial randomized block design with three replications. The first factor was a bioameliorant (P1 = goat manure 10 tons ha−1; P2 = goat manure 10 tons ha−1 + Azolla pinnata 10 tons ha−1; P3 = goat manure 10 tons ha−1 + Sesbania rostrata 2 tons ha−1; dan P4 = goat manure 10 tons ha−1 + A. pinnata 5 tons ha−1 + S. rostrata 1 tons ha−1) and the second factor was rice varieties (Ciherang and Mendawak). The application of bioameliorant increased C-organic of soil by 9.04% to 20.41% and soil nitrogen by 11.76% to 38.24%. The addition of bioameliorant did not cause differences in the weight of the plant between the Mendawak variety (61.34 g) and the Ciherang variety (56.96 g). The most efficient addition of bioameliorant is P3 (goat manure 10 tons ha−1 + S. rostrata 2 tons ha−1) with nutrient uptake efficiency value reaching 5.77%. The use of bioameliorant is expected to be able to substitute the use of inorganic fertilizers and increase rice production.
由于全球气候变化，土壤养分会减少。这是因为气候变化导致降雨强度大，旱季延长。克服这一问题的努力是使用生物改良剂施肥，使土壤养分仍然可供植物使用。2018年5月至8月，在JAMTANI野外实验室进行了观测。本研究采用三次重复的因子随机区组设计。第一个因素是生物改良剂(P1 =羊粪10吨/公顷;P2 =羊粪10吨ha−1 +凤仙花10吨ha−1;P3 =羊粪10吨ha - 1 +田菁2吨ha - 1;单P4 =羊粪10吨ha - 1 +山楂5吨ha - 1 +山楂1吨ha - 1)，第二个因素是水稻品种(赤禾郎和门达越)。施用生物改良剂可使土壤碳有机含量提高9.04% ~ 20.41%，土壤氮含量提高11.76% ~ 38.24%。添加生物改良剂对孟打越品种(61.34 g)和慈和让品种(56.96 g)的植株质量无显著影响，添加最有效的生物改良剂为P3(羊粪10 t ha - 1 +鹿茸2 t ha - 1)，养分吸收效率值可达5.77%。生物改良剂的使用有望取代无机肥料的使用，提高水稻产量。

Abstract Length and shape of rice are important physical qualities that determine public acceptance of a variety and determine the price. Improvement of length and shape of rice requires information on the genetic parameters of these traits. Diallel analysis is one of the methods usually used to estimate the genetic parameters of a trait. The purpose of this study was to estimate the genetic parameters of length and shape of rice using full diallel analysis. The plant material used was a full diallel cross-population of six rice genotypes, namely, Basmati Pakistan, Basmati Delta 9, Inpago Unsoed 1, Inpari 31, Koshihikari, and Tarabas. Thirty-six genotypes consisting of parents, F 1 and F 1reciprocal, were planted using a randomized block design with three replications. The data of rice grain length and length:width ratio were used for diallel analysis using the Hayman and Griffing method-1. The results showed additive and non-additive gene action influencing the length and shape of rice. The effect of the additive gene action was greater than the non-additive gene action, while both broad-sense heritability and narrow-sense heritability were high, revealed that the selection of these traits at the early generation using the pedigree selection method may be considered. Length and shape of rice were not affected by the female parent cytoplasm so that F 2 and F 2reciprocal populations may be combined into one population the next generation.

Abstract The constant variation of people’s lifestyle has been linked to changes in people’s eating habits. The consumption of ready-to-eat (RTE) food products, such as fresh vegetables, salads, dairy, pre-cooked meat, or pre-cooked meals, has increased in all western countries. This study aims at characterization of the Portuguese consumers’ attitude toward chilled RTE meat and dairy foods consumption. The study was performed using a questionnaire survey disclosed through an internet platform. The sample consisted of 350 individuals, who voluntarily answered the questionnaire. The survey included questions to characterize the Portuguese purchase and food safety attitudes related to dairy and meat RTE food products. The questionnaire also included questions for the sociodemographic characterization of the sample involved. According to the results, it is not clear to the customers as which is the safer refrigerated RTE food selling format, pre-packed or foods on request. The participants consider refrigerated RTE dairy and meat food products safer when purchased at the delicatessen department in the supermarket than those purchased at open markets or bazaars. With respect to the customers’ habits, they usually purchase RTE dairy or meat food products mainly from the supermarket, and in pre-packed format. Globally, the results reveal that Portuguese consumers are conscious and follow assertive attitudes toward food safety, contributing to maintain the refrigerated food chain, even when they take the product home.

Abstract The research employs secondary data consisting of time series data on beef prices from the consumer regions (Jakarta, Banten, and West Java Provinces) and the producer regions (East Nusa Tenggara, West Nusa Tenggara, Bali, East Java, and Lampung Provinces) obtained from the Center for Information of Strategic Food Prices period January 2018–July 2022. The analytical model utilizes the estimated VAR (vector autoregression)/VECM (vector error correction model). The mean beef price in Indonesia’s producer regions exceeds the normal level (above the reference price), except for East Nusa Tenggara Province, as well as in the consumer regions, which are significantly above the normal level. Beef prices in the producer and consumer regions have a mutual influence in the current and previous periods. The presence of cointegration implies that in the long term, the beef market in the producer regions (East Nusa Tenggara, West Nusa Tenggara, Bali, East Java, and Lampung) is integrated with the consumer regions (Jakarta, Banten, and West Java Provinces) in Indonesia. The most substantial impact of the shock of beef prices in the region of the largest producer is Lampung Province. This research concludes that there is a cointegration of beef prices; in the long term, the beef market in producer regions is integrated with the consumers in Indonesia. Similarly, the beef market will be integrated into producer regions with the consumers in the short term. The VECM is a beef price forecasting model in the producer and consumer regions, which can be considered to have excellent performance.

Abstract Barrier properties are very important in food packaging; the better the properties, the longer the product can stay fresh in the packaging, which prolongs the shelf life of the product. One way of improving barrier properties is to modifying the existing coatings with the addition of metal oxides, nanoparticles, or natural extracts. The aim of the study was to compare the barrier properties between paper coated with starch and paper coated with starch and black cherry extract mix. Prunus serotina extracts were prepared by ultrasonic extraction in 60°C water. The extracts were then filtrated and evaporated to obtain a constant mass. The reference coatings were prepared by dissolving starch in hot water to obtain a solution of 30%. The experimental coatings were prepared by substituting 10% starch for black cherry extract. Coatings were applied on the paper by laboratory coater in two thicknesses: c.a. 7 and 15 g/m2. The papers were characterised by grammage, coating weight, porosity, and roughness. Barrier properties were tested by following methods: Cobb-Unger, KIT, water vapour transmission rate, and heptane vapour transmission rate. Papers coated with formulations including extract had better barrier properties against oils and waxes, better results in KIT, Cobb-Unger, and heptane vapour transmission rate tests. The results of the water vapour transmission rate test as well as porosity and roughness were the same for papers coated with and without extract addition, they were influenced by the thickness of the coating, not the extract addition. The addition of black cherry extract influenced the barrier properties of the coated paper, and the extract improved the properties against oils and waxes.

Abstract The aim of this study is to analyze the factors that affect the export of chili in Indonesia, determine the most dominant factor, and also the export potential of chili in the importing country. The analytical methods used are panel data analysis with gravity model and trading potential analysis. The results show that the independent variables that significantly affect Indonesia’s chili exports are Indonesia’s real GDP/capita, the real GDP/capita of the destination country, the rupiah exchange rate against the destination country, and the geographical distance between Indonesia and the destination country. The most dominant factor is the rupiah exchange rate. Indonesia’s trade is still under trade (pp > 1), so it can potentially expand the chili trade to importing countries.

Abstract Lablab is a multifunctional crop that is underutilized in Africa. This study was performed to assess Lablab landraces cultivation and distribution, farming systems, and some climatic trends in Lablab production areas in Tanzania. A socio-economic survey was engaged to locate the main production areas using Global Positioning System, while participatory research tools were used to assess farming systems, practices, and challenges perceived in Lablab production. Some weather data were collected to establish climatic trends in Lablab production areas. The study revealed a wide cultivation and distribution of Lablab landraces in five agro-ecological zones with some variations. These variations were influenced by market demand for Lablab in Kenya and its role in subsistence farming. Lablab was mainly produced for conservation agriculture and enhanced soil fertility (27.9%), marketing (22.1%), livestock feeding (21.5%), food during drought conditions (15.4%), traditional purposes (7.4%), regular consumption (3.8%), and other minor uses (1.8%) varied significantly across the zones (χ 2 = 37.639, p = 0.038). The farming systems included intercropping (59.0%), mono-cropping (31.0%), home based gardening (5.0%), crop rotation (3.0%), and relaying cropping (2.0%) with no significant difference across the zones (χ 2 = 15.049, p = 0.314). A wide range of farmers’ practices were noted in Lablab production zone-wise. Unavailability of improved varieties and poor market channels were the farmers’ key challenges in Lablab production. It was further noticed that Lablab was mainly produced in areas with dry conditions. Finally, it was suggested that effort should be enhanced to improve genetic resource conservation, value addition, and market channels to other countries while developing improved varieties in terms of high yielding and drought tolerance.

Abstract Credit accessibility is crucial for sustainable agricultural development. However, the difficulty in accessing credit has caused farmers to take many considerations when taking a loan. This research aims to determine the factors determining access and credit sources for cassava farmers in Lampung Province, Indonesia. Central Lampung was chosen as the research location because it had a total cassava production share of 36%. This study used Isaac’s and Michael’s formulae to determine the total samples. The data were collected by interviewing 263 respondents. Of 263 farmers, only 109 (41.4%) had access to loans. Data were analysed using the Multinomial Logit Regression Model to examine the factors determining access and credit sources for cassava farmers. Marginal effect analysis was also used to determine the probability of changes in independent variables. Regression results showed that the type of credit sources chosen by the farmers was determined by age, income, agribusiness experience, land size, education, organisation membership, and credit experience (R 2 = 89.1%). Partially, age, income, land size, education, credit experience, and business experience significantly influence the funding source. The results indicate that age, agribusiness experience, and land size are the main factors in choosing the types of credit. Land size has the biggest positive influence on farmers’ access to formal banks (11.49%).

Abstract The COVID-19 pandemic has resulted in a change in food demand. In Central Java, during the pandemic (2021), the proportion of expenditure on the grain food group was higher than in 2020; meanwhile, the proportion of the ready-to-eat food group decreased. This study aims to analyze the pattern of food consumption of carbohydrate sources, the influencing factors, and the elasticity of consumption in households in Central Java before and during the COVID-19 pandemic. This study uses data from the National Socio-Economic Survey (Susenas) for 12 districts/cities in Central Java consisting of 9,812 in 2019 and 10,636 households samples in 2021. Data analysis used the Linear Approximation Almost Ideal Demand System (LA-AIDS) method. Results of the study show that the COVID-19 pandemic has caused changes in the household consumption pattern of carbohydrate-source food in Central Java. The proportion of expenditure on rice, wheat flour, shelled corn, cassava, and potatoes has increased. On the other hand, wet corn, instant noodles, and white rice decreased. The price of food sources of carbohydrates and the number of household members positively affect the consumption of food sources of carbohydrates. At the same time, income has a negative effect. There are differences in the effect of the location of the residence on the consumption of food sources of carbohydrates before and during the pandemic. The value of own-price elasticity and income elasticity shows that before the pandemic, rice was a staple good whose consumption was inelastic. Before and during the COVID-19 pandemic, wheat flour, wet-skinned corn, shelled corn, potatoes, white rice, and cassava in the pre-pandemic period was Giffen because the price elasticity was positive, and the income elasticity was negative. Meanwhile, rice during the pandemic, instant noodles before and during the pandemic, and cassava were Veblen goods because their price and income elasticity were positive. Cross elasticity shows that before the pandemic, most of the relationships between food sources of carbohydrates were substitutes, while during the pandemic, most of the relationships between food sources of carbohydrates were complementary.

In Central Java, during the pandemic (2021), the proportion of expenditure on the grain food group was higher than in 2020; meanwhile, the proportion of the ready-to-eat food group decreased. This study aims to analyze the pattern of food consumption of carbohydrate sources, the influencing factors, and the elasticity of consumption in households in Central Java before and during the COVID-19 pandemic. This study uses data from the National Socio-Economic Survey (Susenas) for 12 districts/cities in Central Java consisting of 9,812 in 2019 and 10,636 households samples in 2021. Data analysis used the Linear Approximation Almost Ideal Demand System (LA-AIDS) method. Results of the study show that the COVID-19 pandemic has caused changes in the household consumption pattern of carbohydrate-source food in Central Java. The proportion of expenditure on rice, wheat flour, shelled corn, cassava, and potatoes has increased. On the other hand, wet corn, instant noodles, and white rice decreased. The price of food sources of carbohydrates and the number of household members positively affect the consumption of food sources of carbohydrates. At the same time, income has a negative effect.

Abstract The use of improved soybean varieties is crucial when it comes to the progress of soybean cultivation in Indonesia. This study presents the agronomic performance, seed chemical composition, and bioactive components of 12 soybean genotypes grown in Malang, Indonesia. Parameters included the agronomic characteristics, ash, protein, fat, total flavonoid content (TFC), total phenolic content (TPC), genistein and daidzein contents as well as antioxidant activity. The study found that Dena 1, Dering 1, and Deja 1 had the highest seed yield (2.76–2.84 t/ha), while Dega 1 had the largest seed size (24.69 g/100 seeds). The black-seeded genotype of Detam 1 had the highest protein content (39.79% dw), while GH 63 had the largest amount of total daidzein and genistein. Detam 4 (a black-seeded genotype) exhibited the highest values of TFC, TPC, and antioxidant activity. The agronomic characteristics and TPC significantly correlated, suggesting that both traits are applicable as criteria for soybean breeding selection. Detam 4 and GH 63 are likely promising to be used as gene sources for improving the nutritional and health benefits of soybean genotypes. GH 63 and GH 73 also have the potential for further release as new high-yielding varieties with early maturity and large seed size. Overall, the study provides valuable information on the agronomic superiority and nutritional aspects of improved soybean varieties in Indonesia.
