Abstract Indonesia has a dry land area of 79.69%, with low soil productivity (physical, chemical, and biological), as well as uneven and unpredictable rainfall. The dryland potential is optimally utilized using biofertilizers that can produce microbes to increase soil fertility. This research aims to determine the effects of biofertilizers on dryland improvement and crop production. The study was conducted from February to May 2021 in Central Java, Indonesia. Using a randomized block design in peanut cultivation. Six biofertilizers (Controlled, Agrimeth, BioNutrient, Gliocompost, Agrimeth + BioNutrient, Agrimeth + BioNutrient + Gliocompost) were applied with four replications. The performance of each biofertilizer was assessed based on chemical soil parameters, soil microbe population, plant growth, and yields. The soil in the study area belonged to the Inceptisols group and exhibited moderately acidic pH, low organic carbon content, and low nitrogen levels. However, it had high potential and available phosphorus, as well as moderate potential and high available potassium. BioNutrient and Gliocompost increased available phosphate by 12 and 19%, respectively, due to the presence of Pseudomonas fluorescens and Aspergillus sp. Agrimeth influenced the population of Azospirillum (45–63%) and enhanced phosphate-solubilizing bacteria. Agrimeth + BioNutrient + Gliocompost promoted the growth of the Azospirillum and Trichoderma populations (17–18%), resulting in a 45.04% increase in profits. Biofertilizer inoculation positively affected peanut development, root nodule formation, and yield. This novelty showed the potential of biofertilizers in improving dryland conditions, increasing crop productivity, and contributing to sustainable agriculture in the long term.

Abstract Salinity stress has become the major devastating constraint for rice growth. Halotolerant rhizobacterial nitrogen fixer (HRNF) was investigated for increasing the nitrogenase activity (NA), organic acid (OA), gibberellic acid (GA), and indole 3-acetic acid (IAA) productions, seedling growth, and rice yield. Six N fixers were isolated using Ashby’s (Ab1, Ab2, and Ab3) and Okon’s media (Az1, Az2, and Az3). Furthermore, bioassay was carried out using rice seedling grown on nitrogen-free medium. The Ab3 and Az2 isolates were selected and biomolecularly identified as Pseudomonas stutzeri and Klebsiella pneumoniae, respectively. These selected bacteria were used as active ingredients for Halotolerant rhizobacterial inoculant (HRI) dosage trials (0, 500, 1,000, and 1,500 g ha−1) on simple pot experiments. The Az group isolates had 3–5 times higher ability in fixing N and producing OA, GA, and IAA than the Ab group isolates. Furthermore, N-uptake, number of panicles, filled grain, and the rice yield of HRI treated pots were significantly increased. Application of 1,000–1,500 g HRI ha−1 had resulted in a significant increase in the yield of rice grain (26.10–28.27 g plant−1 or 15.4–25.09%) which was higher than the control. This result concludes that HRI could contribute in enhancing the ability of rice to adapt and grow under saline stress.
盐胁迫已成为水稻生长的主要破坏性制约因素。研究了耐盐根瘤菌固氮剂(HRNF)对提高氮酶活性(NA)、有机酸(OA)、赤霉素(GA)和吲哚- 3-乙酸(IAA)产量、幼苗生长和水稻产量的影响。采用Ashby培养基(Ab1、Ab2和Ab3)和Okon培养基(Az1、Az2和Az3)分离6个N固定物。在无氮培养基上对水稻幼苗进行了生物测定。Ab3和Az2分离株经生物分子鉴定分别为stutzeri假单胞菌和肺炎克雷伯菌。这些选定的细菌作为活性成分，在简单的盆栽试验中进行耐盐根瘤菌接种剂(HRI)剂量试验(0,500,1,000和1,500 g ha - 1)。Az组的固定N和产生OA、GA、IAA的能力是Ab组的3-5倍。氮素吸收量、穗数、灌浆粒数和水稻产量均显著提高。施1000 ~ 1500 g HRI hm - 1可显著提高水稻产量(26.10 ~ 28.27 g hm - 1或15.4 ~ 25.09%)，高于对照。由此可见，HRI对提高水稻对盐胁迫的适应能力和生长能力具有一定的促进作用。

Abstract This research focuses on the development of utilizing Grade-C kenaf fibers (poor quality) produced from plantations in Pesanggarahan village, Lamongan regency, Indonesia, to produce alternative textile materials for textile craft and textile products. High-quality kenaf fibers have been utilized in the automotive, pulp and paper, and geotextile industries, while low-quality kenaf fibers are considered less potential and have only been used as gunny sacks. This research was conducted through an exploration and experimental approach, dividing the process into four stages, namely: (1) scouring stage using standard degumming of cellulose fibers; (2) testing strength and elongation of fibers; (3) bleaching stage of fibers; and (4) textile exploration stage with design and craft approach to create yarn and fabric weaving and crochet techniques, and the results were quantitatively tested to identify their mechanical and physical properties. This is beneficial as a solution to add value to a material to produce material trends for the development of textile craft products.

Abstract Feed certification is released by authorized third parties as external cues indicating that products have met standard quality. However, farmers do not always take certification as the main consideration in product selection because of insufficient knowledge or they are skeptical about certification. This research aims to analyze the effect of feed certification, company image, opinion leader, perceived product quality, customer trust, and satisfaction to layer farmers’ customer loyalty. Respondents were selected by using purposive sampling with the criteria that respondents were layer farmers with experience for at least 1 year and customers of concentrate or ready-made feed. Data were collected by using questionnaire and analyzed with the partial least square. Results show that feed certification influenced perceived product quality with β = 0.127 and p ≤ 0.1; then, company image and opinion leader influenced perceived product quality with, β = 0.690 and β = 0.157 at p ≤ 0.05. Perceived product quality affected customer trust (β = 0.699, p ≤ 0.01) and customer satisfaction (β = 0.689, p ≤ 0.05). Then, customer trust and customer satisfaction positively influenced customer loyalty with β = 0.507, and β = 0.414 at p ≤ 0.01. Research findings indicated that feed certification was considered by layer farmers in feed purchasing behavior. However, company image was played as the most important factor among opinion leader and feed certification. These results implied that besides maintaining company image and the role of opinion leaders, feed mills and authorized institutions still urge to promote the importance of certification as product quality indicator.

Abstract Introduction: Listeria monocytogenes is an opportunistic foodborne pathogen that can cause death to infected humans. The bacterial pathogen was frequently associated with food-borne origins including seafood. Thus, the present study aimed at screening anti-listeria-producing lactic acid bacteria (AL-LAB) isolated from the intestinal tracts of wild gilt-head seabream (Sparus aurata). Materials and Methods: Lactic acid bacteria (LAB) were isolated from the intestinal tracts of 15 wild gilt-head seabreams and screened for antimicrobial activity against Listeria monocytogenes. LAB isolated with the strongest anti-listerial activity was identified and further characterized for its anti-listerial compounds, followed by testing its protecting capacity on experimentally contaminated salmon fillets. Results: Three out of 52 LAB showed antagonistic activities against the foodborne pathogen. Of these 3, an isolate with the strongest inhibitory activity was obtained from strain MA115 (>400 AU). Based on its 16S rDNA sequence, strain MA115 had 99% similarity to Enterococcus faecium (Acc. Nb: MG461637.1). Further in vitro assays showed that the anti-listerial compound was very sensitive to proteinase K which suggested that it is a bacteriocin-like inhibitory substance (BLIS). In addition, the BLIS was resistant to a wide range of pH (2–10), and low (4 to −20°C) as well as high temperatures (30−121°C). In addition, the BLIS showed bactericidal activity on L. monocytogenes in artificially contaminated Salmon fillets stored at 0°C. Conclusion: The BLIS produced by Enterococcus faecium strain MA115 has the potential for application to improve food safety, although further studies are still required to specifically identify the BLIS, for biopreservation purposes.

Abstract Small-scale coffee farming in Indonesia faces low productivity due to poor farming practices and low-quality planting materials. It highlights the need for improved coffee varieties that meet farmers’ preferences. Given the vulnerability of coffee farming to climate change, participatory breeding programs that involve collaboration between researchers and farmers to develop a climate-adapted variety are essential. This study used survey data from Gayo Highland, Aceh, Indonesia, to investigate farmers’ perception of the importance of climate-related attributes in a coffee variety, including those developed through a participatory breeding program, and the determinant factors. The result shows that farmers rated climate-related attributes as the least important (average score 0.36) compared to others, such as coffee productivity (1.57) and quality (1.22), resistance to pests and diseases (0.96), and input-use efficiency (0.57). This finding suggests a lack of awareness among farmers about the importance of climate issues in coffee farming. The estimation results also indicate that coffee extension activities have a negative association with farmers’ perceptions of the importance of climate attributes. This study recommends inclusive and targeted climate campaigns to increase farmers’ concern, awareness, and knowledge about the threats of climate change to coffee farming through strengthening advisory services.

Abstract The potential for vegetables in Indonesia is enormous. However, activities both upstream and downstream are still not well developed so that Indonesia is still importing horticulture to meet domestic needs. Because the potential for horticulture has not been maximized, the Ministry of Agriculture is holding a Horticultural Village program, one of which is in Central Java. The Horticultural Village Program that has been running requires a strategy to increase its sustainability. This research was conducted in Central Java to determine strategies to improve the sustainability of the horticultural village program. The method used in this study is multidimensional scaling (MDS) with the rapid appraisal for horticultural village (RAP-HORVI) technique or RAP-HORVIs. This research method will produce an index value that will determine the sustainability status of all dimensions used, namely, input, process, output, and outcome. The result of this analysis is that the Horticultural Village in Central Java is in a quite sustainable status. The results of this MDS show that 12 sensitive attributes can be used as strategies in increasing the value and sustainability status of Horticultural Villages in Central Java, namely, business management training, availability of production tools and materials, suitability of production input facilities, technical training, availability of capital, optimizing the use of infrastructure assistance, checking on farmers/micro, small, and medium enterprises beneficiaries of SK CPCL, intensive assistance by trainers, increasing planting area, increasing the number and variety of plant types, planning the area of land ready for planting, and increasing business capital.

Abstract The current study looks at a variety of factors that affect eating patterns. This is about internal and external aspects that lead to a thorough assessment of consumer behavior, with an emphasis on driving forces and obstacles that significantly affect each consumer’s food preferences. The information is based on questionnaire research of traditional and fiber food consumption as well as specific consumer purchasing behaviors. The results of the questionnaire survey were analyzed using qualitative aspects analysis and other statistical methods (ANOVA, t-test). The study’s goal is to provide comprehensive strategies that encourage and support the intake of nutritious meals, especially in light of how different food motivations and knowledge factors influence Lebanese consumer behavior. Based on the findings, individual eating motivation and its impact on consumers’ behavior in Lebanon when making food purchase decisions were found. Sources of potential influences include information, the social environment, and environmental variables. Processes like social learning influence the interplay between these components as well as food choices and eating habits. As a result, future programs to encourage healthy eating habits might profit by putting more of an emphasis on learning principles and food preferences when programs are implemented.

Abstract Visible–shortwave near-infrared spectroscopy has been used for internal quality measurement, but the optical penetration to the thickness of fruit skin becomes a challenge. This research aimed to develop partial least square regression model for the soluble solid content (SSC) measurement of fruits having various skin thicknesses, namely dragon fruit, tomato, guava, sapodilla, and banana. The spectra of each fruit were taken in a reflectance mode over a wavelength range of 400–1,000 nm. The best models obtained from banana and sapodilla yielded determination coefficient of prediction (R 2 p) of 0.88 and 0.90 and root mean square error of prediction (RMSEP) 0.39 and 0.38°Brix, respectively. The banana and sapodilla SSC prediction models should be able to be used carefully in a variety of applications. Tomato and guava had moderately thinner skin but had the lower R 2 p of 0.64 and 0.76 and the RMSEP of 0.17 and 0.26°Brix, respectively. The poorest model was yielded by dragon fruit, which had the thickest skin with the R 2 p of 0.59 and the RMSEP of 0.40°Brix. The model for guava, although having low R 2 p, can still be utilized as a screening criterion and in some other ‘approximate’ applications. However, the SSC prediction model for tomatoes and dragon fruit is not recommended to use and requires additional research. In addition to the effect of skin thickness, other fruit morphological influences the result of this study. Internal structure and seed number influence the reflection optical geometry, which also affects the SSC prediction model.

Abstract Soya bean occupies a crucial space in solving the problem of poverty and food insecurity in sub-Saharan Africa (SSA), given the status of the crop as a multipurpose crop. Despite the enormous importance of this crop, the production is still very low in SSA, particularly in Nigeria. This study, therefore, examines the performance of soya bean production using technical efficiency as a yardstick for measuring performance. Primary data were collected with the aid of a structured questionnaire and scheduled interview from 100 soya bean farmers selected using a purposive sampling technique. The data were analysed using descriptive statistics, profitability analysis, and stochastic frontier analysis. The results reveal that the average age was about 45 years with close to 5 years of farming experience. The average household size in the study area was 5 with a mean farm size of 1.8 hectares. The net farm income was ₦37753.92k, while the average rate of return to investment (return per naira invested) was 1.49. The overall mean technical efficiency score was about 56%. This suggests that farmers are relatively efficient in general. There is, however, a gap to improve their farming operations through adequate training on seeds and agrochemical use because both contribute to their inefficiencies.
