This study aims to determine body weight, body weight gain, and body measurements of male and female Kerinci ducks, as well as to determine the diversity of MSTN genes and the association of the MSTN gene on body weight, body weight gain, and body sizes in Kerinci ducks. The materials used were 96 Kerinci ducks and 96 Kerinci duck blood samples. Data analysis included: T-test, T2-hotelling, Principal Component Analysis (PCA), genotype frequency, allele, Hardy-Weinberg equilibrium, Heterozygosity, and PIC. The results showed that body weights at 2 and 3 months of age, body weight gain of 2-3 months and body sizes of 3 months old male Kerinci ducks were significantly different (P <0.05) higher than female Kerinci ducks. Body size markers of male and female Kerinci ducks were the length of the sternum, the length of the shank, and the circumference of the shank, while the shape identifier was the length of the wings. The MSTN|MboI gene in Kerinci ducks was polymorphic. The population of Kerinci ducks was in Hardy-Weinberg equilibrium (P<0.05). Kerinci duck population heterozygosity showed H0<He. The MSTN|MboI gene was associated with BB, PBB, and body measurements of male and female Kerinci ducks, and the best genotype was (-/-).

The nutritive potency of rubber leaves (Hevea brasiliensis) as forage/feed for goats was analysed in vivo. Twenty four male and female postweaned Etawah grade kids aged 4-6 months with body weights between 11 to 26 kg were allocated into three treatment groups (i.e. T0, T1 and T2) with eight repetition designed as Randomized Block Design. Treatment diet T0 consisted of 0% rubber leaves, 80% other forages and 20% rice bran. Treatment diet T1 consisted of 40% rubber leaves, 40% other forages and 20% rice bran, and Treatment diet T2 consisted of 60% rubber leaves, 20% other forages and 20% rice bran. The results showed that DM, DE and DP consumptions, ADG and FCR of the T0, T1 and T2 treatment groups were respectively: 1008, 1040 and 1199 g DM; 2.8, 2.9 and 4.0 McalDE; 31.9, 42.9 and 59.8 g DP; 58.2, 85.7 and 76.1 g/head/day; 25.6, 15.9 and 18.0. It can be concluded that the use of rubber leaves and its branches with composition of 40 to 60% of goat diets can increase energy and protein consumptions, increase body weight gain, decrease FCR, and subsequently increase the production efficiency of the goats.

This study aims to identify and inventory the fishing units in Tanjung Solok Village, Kuala Jambi District, Tanjung Jabung Timur Regency. This research was conducted in June-July 2021. The method used in this study is a survey method, with direct observations in the field and conducting interviews with fishermen and noting the fishing units used by fishermen in Tanjung Solok Village. The sampling method is a census of 106 fishermen who have fishing units and domiciled in Tanjung Solok Village. The data collected in this study include general biographical data of fishermen, ships or boats used to catch fish, fishing gear used, and catches while fishing. The data analysis used in this research is Descriptive Data Analysis. Fishermen in Tanjung Solok are aged between 20 and 70 years with elementary, junior high and high school education and work as main fishermen, fishermen and side fishermen. The fishing vessels used are classified as outboard motor boats, non-motorized boats and motor boats made of fiber or wood with ship sizes of 1 to 4 GT. There are 7 types of fishing gear used, namely Gillnet, Mini Trawl, Pull Trawl, Splint, Rawai, Net, and Clam Stick and are dominated by fishing gear that is easy to operate and cheap. The most widely used fishing gear is the Gillnet. The fishing area for Tanjung Solok fishermen is around the territorial sea which is no more than 12 miles from the coastline because the fishing units are classified as small-scale. The fish caught by fishermen vary from shrimp and gulama fish, happy fish, side fish and shellfish.
