Food security is one of the crucial issues in developing countries. The Food and Agriculture Organization (FAO) identifies four food security components: availability, affordability, utilization, and stability. Bengkulu Province, until 2023, is the second poorest province on the island of Sumatra. This has an impact on food affordability, which is a component of food security. There needs to be mapping or grouping in each region in Bengkulu Province so that the policies formed and implemented can be more optimal. This study aims to group and map areas or districts in Bengkulu Province that have similar characteristics based on aspects of food availability, food affordability or physical access to food, and aspects of food utilization. Biplot analysis describes regional characteristics and variable correlations in a two-dimensional graph. The results of grouping food security areas based on the characteristics of the three aspects are three clusters. The first cluster consists of Kaur, South Bengkulu, and Lebong. The second cluster consists of Central Bengkulu, Mukomuko, and North Bengkulu. The third cluster consists of Rejang Lebong, Seluma, and Kepahiang. The first cluster tends to have good food security because its characteristics are relatively close to the food availability and utilisation indicators. The second cluster has strong attributes as an indicator of food affordability. The third cluster has characteristics that describe indicators of lack of electricity, clean water, poverty rate, and life expectancy.

The program aimed to produce high-quality bokashi compost, develop certified chilli seeds, and process cow's milk into flavored milk products. The results demonstrated that combining raw materials from the farmyard with dairy farm yard produced bokashi compost with favorable nutrient content: total nitrogen at 1.3%, phosphorus at 0.99%, potassium at 1.3%, organic carbon at 26.12%, and a C/N ratio of 17.18 qualified the standards of SNI 19-7030-200. Additionally, a comparison of 4 chilli hybrids with a combination revealed that the hybrid combination between UNIB C H63 x UNIB C H43 in the one plot achieved greater plant height and canopy area. However, although differences in yield components were not statistically significant, the single cropping of hybrids UNIB C H13 and UNIB C H53 significantly improved the resistance to yellow leaf curl disease. Lastly, the flavoured milk development resulted in a high-quality product with a fat content of 3.91%, protein at 3.30%, lactose at 4.96%, and a specific gravity of 1.032. Overall, the program successfully met its objectives, producing quality compost, promising chilli hybrids, and nutritious flavored milk.

This study aimed to estimate the value of genetic correlation and the regression equation between body weight and body measurements of male Ongole crossbred (PO) cattle across various age groups. The sample used consisted of 80 male PO cattle divided into four age groups: I0 (<18 months), I1 (18 to 24 months), I2 (24 to 30 months), and I3 (>30 months). The parameters observed include body weight (BW), body length (BL), body height (BH), hip height (HH), and chest circumference (CC). Correlation and regression data were analysed using the Excel program; the regression between body weight and body size was analysed using the best subset regression method. The results showed a strong to robust genetic correlation between body weight and body size, with the highest correlation value in chest circumference (CC) in all age groups (0.92-0.98). The regression equations revealed that chest circumference had the highest regression coefficients (ranging from 2.36 to 3.87), indicating that it is the most reliable body size measurement for predicting body weight in PO cattle. This study concludes that chest circumference can be used as a reliable parameter to estimate the weight of PO cattle in various age groups, especially for farmers who do not have access to scales.

Meat refers to parts of an animal's body, such as liver, kidneys, brain, and other muscle tissues that are edible, and meat has a fairly complete nutritional content. Meatballs are a type of food popular in Indonesia, but are prone to spoilage due to the activity of microorganisms. The production of beef meatballs with the addition of moringa leaf powder (Moringa oleifera) can inhibit microbial growth and affect the quality of beef meatballs. This study aims to evaluate the effect of Moringa oleifera (Moringa leaf flour, MLF) addition on total microbes and organoleptic of beef meatballs, including color, texture, taste, and preference for color, aroma/smell, texture, and flavor. The research method used a completely randomized design (CRD) with four treatments: meatballs without the addition of MLF (T0) and meatballs with the addition of MLF 1% (T1), 2% (T2), and 3% (T3). The parameters observed included measurements, total microbes, and organoleptic characteristics, which included hedonic and sensory quality tests of beef meatballs. The results showed that the addition of moringa flour had a significant effect (P<0.05) on the results of hedonic and organoleptic quality tests but had no significant effect (P>0.05) on total microbes. The study results show that adding MLF at different levels does not effectively suppress the microbial growth of beef meatballs. Adding MLF with different levels in beef meatballs does not effectively suppress microbial growth. The addition of MLF in the hedonic and organoleptic quality tests significantly affected color, texture, smell, and taste, and was still acceptable to the panelists.

Pak choi plant (Brassica rapa L) is a type of vegetable that is popular and loved by the public. This cultivation cannot be separated from pest attacks. Crocidolomia pavonana F. (crop caterpillar) is an important pest that causes severe damage to Pak choi plants. Pest control with the application of synthetic chemical insecticides causes resistance to crop caterpillars, kills natural enemies of insect pests and hurts the environment and human health. Another environmentally friendly alternative for controlling C. pavonana is needed. It is necessary to use vegetable insecticides. Jengkol skin and kabau skin have the potential as plant-based insecticides to control C. pavonana. This research aims to find concentrations of jengkol and kabau skin extracts (vegetable insecticides) that are effective in preventing C. pavonana on Pak choi plants. This research used a Completely Randomized Design (CRD). It was carried out in two stages, namely testing the effectiveness of jengkol and kabau skin extracts on C. pavonana in the laboratory. Laboratory tests were carried out with three treatments of jengkol and kabau skin extract concentrations at concentrations of 4%, 6% and 8% respectively, repeated five times. Observations were carried out for a week. The variable observed was larval mortality. The laboratory test research results showed that 66% mortality occurred in kabau skin extract at a concentration of 8%, and in jengkol skin extract at a concentration of 8%, causing 53% mortality of crop caterpillar larvae.

This study aimed to estimate genetic and phenotypic variability, as well as heritability values, in 41 Cayenne pepper cultivars based on vegetative traits. The research was conducted from May to October 2024 at the Experimental Farm of the Faculty of Agriculture, University of Bengkulu, situated in Beringin Raya village, Bengkulu City, at an elevation of 10 m above sea level. A Randomised Complete Block Design (RCBD) was employed with a single factor consisting of 41 cultivars with three replications, each comprising 20 plants per replication. The results revealed a wide range of genetic variability for traits such as plant height, first dichotomous height, number of leaves, leaf area, leaf greenness, number of dichotomous points, canopy area, stem diameter, shoot fresh weight, and shoot dry weight. High phenotypic variability was observed across all evaluated traits. High heritability was found in the trait of first dichotomous height. Moderate heritability was observed for plant height, number of leaves, leaf greenness, number of dichotomous points, canopy area, shoot fresh weight, and shoot dry weight. Low heritability was detected in leaf area, stomatal density, and stem diameter.

Bengkulu is one of the provinces located on the island of Sumatra, boasting a significant agricultural sector. One of the leading agrarian commodities in Bengkulu Province is oil palm. Oil palm in Bengkulu is planted in coastal areas. One of the key factors supporting oil palm fruit production is a healthy soil arthropod ecosystem. Soil arthropods play an essential role in the oil palm plantation ecosystem. As organisms that live in the soil, these animals help maintain soil and plant health, improving soil structure and nutrient availability for oil palm plants. This study aims to obtain initial data on the diversity of soil arthropods and their roles in smallholder oil palm plantations on the coast of Bengkulu. This study began with sampling oil palm plantations around the coast of Bengkulu. The areas that will be used as study locations include Sungai Suci, Danau Gedang, and Pekik Nyaring. Arthropod sampling was carried out by installing pitfall traps in both areas, which were determined diagonally in a 200 m² area, with 20 pitfall trap units per location. Arthropod species were identified based on morphology, and the type and number of populations were recorded. The Shannon-Wiener diversity index, dominance index, and evenness index measure analysis of biodiversity data. The results of the study showed that in the majority, the diversity of soil arthropods in the three sampling areas was moderate, the dominance of arthropod types was low to moderate, and evenness was moderate to high.

This study aims to optimise the growth of Superior Balitbangtan (KUB-2) chickens through feed restriction during the starter period and its effect on the recovery phase. This study used 100 two-week-old KUB-2 chickens, placed in 20 cages measuring 70 cm x 70 cm x 60 cm, with each cage containing 5 KUB-2 chickens. The study employed a Completely Randomised Design (CRD) with four treatments and five replicates. The variables observed were feed intake, body weight gain, feed conversion ratio (FCR), Growth Rate, and Income Over Feed Cost (IOFC). The research showed that applying 20%, 30%, and 40% feed restriction had a significant effect (P < 0.01) on decreasing feed intake and body weight gain, but had no significant effect (P > 0.05) on the feed conversion ratio during the 4 weeks of treatment. During the recovery phase, ad libitum feeding had a significant effect (P < 0.05) on feed intake, but did not affect body weight gain or feed conversion ratio. Throughout the study, feed restriction followed by recovery had a very significant effect (P < 0.01) on feed intake and a significant effect (P < 0.05) on body weight gain and feed conversion ratio. This study concludes that the 20% feed restriction treatment showed the best performance, with a feed intake of 339.97 g/bird/week, body weight gain of 98.35 g/bird/week, a feed conversion ratio of 3.46, a growth rate of 0.227, and an Income Over Feed Cost (IOFC) of Rp. 14,815.
