Expanding agricultural land by using sloping dry land can be detrimental to the environment due to soil erosion and degradation. However, cover crops can be one of the technologies applied to reduce these risks. Arachis pintoi is one of cover crops that can be used as bio mulch on agricultural land. The study aimed to evaluate the effect of A. pintoi bio mulch on soil nutrient contents and maize plant growth at different slopes. A nested randomized block design was used in the study. Two levels of land used as the main factor and the type of mulch consisting of five levels (without mulch with weeding, without mulch without weeding, silver-black plastic mulch, straw mulch, and A. pintoi bio mulch) were used as the second factor. The results showed that A. pintoi bio mulch significantly increased the P content of the soil and could potentially increase several other macronutrients, especially C-organic, N, and Ca. The use of A. pintoi bio mulch with a cover technique that was left to cover the entire soil surface suppressed the growth and yield of maize plants compared to the control treatment.

Genetic improvement through intensive selection in broilers for economically important traits such as body weight, growth rate, feed efficiency, and carcass quality plays a role in increasing the productivity and efficiency of the broiler industry. Good maintenance management is needed by paying attention to the quantity and quality of feed as well as comfortable and controlled environmental conditions. The environmental factor that is often the focus of attention is the temperature of milieu. During the brooding period aged 0‒21 days, the Day Old Chick cannot regulate its body temperature perfectly and still influenced by ambient temperature. Therefore, it is necessary to study the effect of brooding temperature on the performance of broiler at PT New Hope Indonesia's customers, to find the problems in regulating brooding temperatures along with solutions, evaluations, and improvement plans. Observations were made for 21 days in a semi-closed house with a population of 22,000 Cobb strain broiler. The research method used is data recording observation. The primary data were average brooding temperature for 21 days, depletion rate, feed consumption, body weight, feed conversion ratio (FCR), and production index. There was a deviation in body weight and FCR at the age of 11‒14 days due to the restriction of the heater until the age of 14 days and the wind speed at night which was more than 0.3 ms-1. With the corrective action of wind speed regulation, an effective temperature close to the thermoneutral zone and optimal production performance was obtained until the end of the brooding period.

The soybean agribusiness institutions have important roles to support the increased soybean production in Central Java. The purpose of this study was to analyze the levels of performance and importance of farmers in the institutional performance of soybean agribusiness in Central Java. This research uses descriptive analytical method, with the technical implementation of research using survey methods. This research was conducted on September - December 2022 with a sampling technique using a purposive sampling on 110 respondent farmers. Data analysis carried out in this research is Importance and Performance Analysis (IPA). IPA is used to compare the level of importance of soybean farmers with their levels of performances. Before being analyzed using IPA, each attribute was tested for validity and reliability, and from the test results it was found that each attribute was declared valid and reliable. The results of the analysis show that one of the attributes that is included in quadrant I and needs to be a priority for improvement is the need to determine the Harga Pokok Produksi (HPP) for soybeans by the government and the need to increase the subsidized fertilizer program. Attributes that fall into quadrant II and whose performances must be maintained include the existence of collector traders, the existence of a soybean seed assistance program, and the availability of quality soybean seeds. Attributes that are included in quadrant III and are the second priority for repairing and improvement are the need for storage granaries, partnerships with companies, and the easy access to financing services. Meanwhile, the attributes that enter quadrant IV and can be ignored are the availabilities of water, labor, and farming infrastructure.

Yogurt is a dairy product that is processed into a fermented drink using lactic acid bacteria. Smoothies are drinks made from fruit or vegetables containing milk, yogurt, or honey. Strawberry Rosella Yogurt Smoothie is yogurt that has been processed by reducing the water content and adding rosella flower extract and strawberry jam. Before being marketed, these products need to be tested for safety and market opportunities. This study aims to analyze the physicochemical characteristics, microbiology, and market tests of strawberry rosella yogurt smoothies in adolescents and adults in Bogor. The physicochemical characteristics tested included pH, water activity (aw), viscosity, and total titrated acid. The microbiological parameters tested were total lactic acid bacteria and Salmonella sp. The market parameters tested include analysis of consumer perceptions and preferences and their correlation with yogurt consumption patterns. The market test was carried out using 100 respondents consisting of 50 students from SMAN 1 Bogor and 50 students from IPB University. The results showed that the physical properties (pH, water activity, viscosity, and total lactic acid) fulfilled the SNI yogurt quality requirements. The chemical properties or nutritional content and microbiological properties of yoghurt smoothies have met the requirements for yoghurt quality standards based on SNI. The results showed that respondents had good perceptions and preferences on the attributes of smoothie yogurt. Consumer preferences regarding the appearance of the packaging in general, color, ingredient content, packaging information, and appearance of the contents of the yogurt are generally positively correlated with the price range of yogurt that consumers buy. Strawberry Rosella Yoghurt Smoothie is safe for consumption and can be marketed.

Shallot productivity relies on diverse environmental conditions, including soil fertility. Compost is an organic material that is crucial for the improvement of soil health and fertility. Compost amendment could be employed on shallot to improve its growth and productivity. This study aims to investigate the effect of 4 different composts amendments, processed with 4 different bioactivators, on the shallot growth (Bima–Brebes variety), the dynamic of culturable microbes, and nutrient content on the growth medium inside the polybag. Treatments include a mature compost processed with no biactivators (K0), and with the bioactivator Bioaktimo (K1), Beyonic Startmik (K2), indigenous (K3), and the mixed of K1, K2, and K3 (K4). Measured parameters on shallot growth include plant height, number of leaves, stem diameter, wet and dry weights of shallot bulb, root, and above-ground biomass, and chlorophyll content. In addition, physical, chemical, and biological characteristics of the initial planting medium on the polybag were determined. The result showed that compost amendment significantly increased all parameters tested, except chlorophyll content, when compared to the control and the treatment with 100% chemical fertilizer. The best shallot growth was found in the treatment with soil planting media of 75% Soil + 25% Compost K4 (TK5).

Moringa (Moringa oleifera) seeds contain good nutritional constituents and several components that can potentially reduce cholesterol levels, namely oleic acid, phytosterols, and dietary fiber. However, it tastes bitter, so it needs to be treated so that the bitter taste disappears but does not affect much of the content that can lower cholesterol. This study aims to get moringa seeds that are not bitter and have the potential to prevent hypercholesterolemia. The soaking treatment of peeled moringa seeds in either water or 3.5% NaCl salt, followed by 80 minutes of boiling, resulted in moringa flour with a very low bitter taste. The oleic acid content of the seed flour from soaking treatment with water or salt by boiling for 40 or 80 minutes is still high, in the range of 69–72%. Oleic acid is known to improve blood cholesterol profiles. The content of phytosterols, one of the cholesterol absorption inhibitors, from moringa flour treatment of 27–29 mg/100 g dw, is much higher than control flour (15 mg/100 g dw). The dietary fiber content of moringa seeds (total dietary fiber, soluble dietary fiber, insoluble dietary fiber) generally does not change after treatment. The results showed that soaking moringa seeds in water for 24 hours, followed by boiling for 80 minutes, produced moringa flour that can be used to develop hypercholesterolemia prevention foods.

Gotu kola is one of the medicinal plants that is widely used because of its various nutritional content. In general, the cultivation only uses inorganic fertilizers, which have long-term effects that are not good for the environment. The use of organic fertilizers is an effort to produce high-standard products. Rabbit urine liquid organic fertilizer and goat manure are alternative types of fertilizer that can be given. Therefore, this study aimed to determine the response of giving liquid organic fertilizer of rabbit urine and goat manure and their interaction with the growth and yield. The study used a Factorial Randomized Block Design (RBD). The first factor was rabbit urine liquid organic fertilizer (LOF) with a concentration of 0, 2, and 4%. The second factor was goat manure with doses of 0, 37, and 75 g/polybag. The results showed that applying rabbit urine (LOF) and goat manure increased the growth and yield of gotu kola. Application of 2% rabbit urine LOF significantly increased stalk length compared to controls. Gotu kola plants given 37 g/polybag of goat manure produced stolons that were significantly longer than those treated with goat manure 75 g/polybag and had significantly heavier roots than other treatments. The interaction of rabbit urine LOF and goat manure application had no significant effect on all observed variables.

Climate change affects the agricultural sector, which has an impact on droughts or floods. Ecological agriculture is expected to be an adaptation method for reducing losses due to climate change. This study aims to describe the characteristics of farmers, ecological rice cultivation practices, and the relationship between the two parameters. The research in Kendayakan Village, Terisi District, Indramayu Regency, involved 60 farmers surveyed using accidental sampling techniques in February 2022. The data collected include farmer characteristics (age, education, land area, land ownership status), length of farming, sources of farming knowledge, participation in groups, and rice cultivation practices. Data on the application level of ecological agricultural practices were analyzed descriptively and tested usin the Spearman Rank correlation between farmer characteristic variables and rice cultivation practices. The results showed that farmers were of productive age, with a low level of formal education but experienced and active in local organizations. The level of application of farmers' ecological agriculture is moderate. The return of straw, tillage, and control of plant pests are the components of cultivation that are least following the principles of ecological agriculture. Internal factors of farmers that correlate with the components of ecological rice cultivation are age, education, length of farming, source of farming knowledge, and land ownership status.

The goals of this study were to explore and identify entomopathogenic fungi, as well as determine the most effective application techniques to control S. frugiperda from exploration of infected Spodoptera frugiperda larvae in Purbalingga Regency. The research was carried out at the Plant Protection Laboratory, Faculty of Agriculture, Jenderal Soedirman University, from January to May 2022. Samples were collected by purposive random method. The study used a Complete Randomized Design, consisting of two factors, namely the type of entomopathogenic fungus and the application technique, with 9 combinations and 3 replications. Observed variables include mortality, feeding activity, growth, and reproduction of larvae. The results showed that (1) the results of exploration of entomopathogenic fungi were from the genus Metarhizium sp. and Penicillium sp. (2) single treatment of Metarhizium sp. is more effective than Penicillium sp. in killing S. frugiperda larvae. Fungi Metarhizium sp. and Penicillium sp. decreased feeding activity, length of three-instar larval period, and number of eggs, respectively 24.99 and 15.99%, 4.71 and 2.46%, 9.18 and 8.04% against controls. (3) single treatment of feed soaking method decreased mortality by 55.18% than other methods. Spraying the larval body decreased mortality by 44.84% compared to other methods. The method of application did not affect the feeding, growth and fecundity activity of larvae. (4) The combined treatment of Metarhizium sp., spraying the larval body, and soaking feed had a mortality percentage of 60%. Interaction treatment of the fungus Metarhizium sp. and the method of application lowered the feed power by 16%. The decrease in the period of three instar larvae to pupae and the largest number of eggs in the combination treatment of Metarhizium sp. and spraying of larval bodies was 6.34% and 11.20% respectively compared to controls.

Microbial contamination on chicken meat can be inhibited by applying natural antimicrobials. Dayak onions (Eleutherine palmifolia (L.) Merr.) are reported to inhibit the growth of Escherichia coli and Staphylococcus aureus. This study aims to confirm and apply dayak onion extract (EBD) as an antimicrobial in fresh chicken meat. The observation parameters were the microbiological quality and physical properties of chicken meat after inoculation with E. coli and S. aureus and dipped in EBD solution with concentrations of 0, 3.0, 9.0, and 15.0 mg/mL for E. coli, and 0, 2.5, 7.5, and 12.5 mg/mL for S. aureus. The results showed that EBD-70% ethanol showed better bacterial inhibition than EBD-96% ethanol. Inhibition for both microbes can be achieved by concentrations of 3.0 and 2.5 mg/mL EBD, as visually observed in liquid media. Concentrations of 15.0 and 12.5 mg/mL showed significant results in reducing the total microbes of both types in chicken meat after 12 hours of room temperature storage (28±2°C) and 9 days of refrigerator storage (5±1°C). A combined application of 15.0 and 12.5 mg/mL EBD and refrigerator temperature can be recommended to reduce total E. coli and S. aureus and maintain the Aw and pH of the chicken meat.
