Abstract. Ibrahim A, Artama WT, Budisatria IGS, Yuniawan R, Atmoko BA, Widayanti R. 2021. Regression model analysis for prediction of body weight from body measurements in female Batur sheep of Banjarnegara District, Indonesia. Biodiversitas 22: 2723-2730. Bodyweight is an important aspect of livestock management. The present study was undertaken to estimate correlation coefficients between biometric traits and identify best predictor of body weight in female Batur sheep from body measurements. Data on body weight and body measurements (body length: BL, chest girth: CG and withers height: WH) were collected from 73 female Batur sheep in Batur Village, Banjarnegara District, Central Java Province, Indonesia. Batur sheep were grouped into 3 categories based on their age, namely groups <1.5 years, 1.5-2.5 years and >2.5 years. The data were analyzed using simple, multiple, and automatic linear regression methods using the SPSS computer software version 25 platform. The correlation coefficient, coefficient determination, adjusted coefficient determination, residual standard error, Akaike information criterion, Bayesian information criterion, and Akaike information criterion corrected were used to determine the best regression formula for the prediction of BW. The average BW (kg), BL (cm), CG (cm), and WH (cm) of 49.27, 63.11, 91.41, and 56.82, respectively was observed in the present study. The correlation coefficients of 0.433, 0.866, and 0.369 for BW with BL, CG, and WH were observed in the present study. The best prediction of BW using two predictors (BL and GC) was BW =-56.522 + 0.509BL + 0.843CG, followed by using three predictors (BL, CG, and WH) was BW =-57.897+ 0.505BL + 0.839CG + 0.034WH, and using the only one predictor (CG) was BW =-28.443 + 0.905CG. The study revealed that CG and its combination with other linear body measurements can effectively define the body weight in Batur sheep. However, the highest R2 of 0.782 was observed when CG and BL were used as predictors.

“…Indonesia is an archipelagic country that consists of approximately seventeen thousand islands. Indonesia has long been considered a mega biodiversity country, especially in maritime sectors (Nuryadin et al 2016;Setyobudi et al 2019;Ibrahim et al 2020). Indonesia's vast marine area has very high potential, for example for food sources such as Mackerel (Scomberomorus spp.)…”

Abstract. Widayanti R, Nugroho HA, Megarani DV, Widiasih DA, Pakpahan S. 2021. Revealing Spanish mackerel’s diversity in Indonesian through local commodities in the fish market. Biodiversitas 23: 624-630. The objective of this study was to explore the diversity of Spanish mackerel in Indonesian Archipelago based on commodities offered in local fish markets. Eighteen specimens were collected from six different fish markets around the Indonesian archipelago. According to Wallace Line, the cytochrome B sequence was used as a genetic marker to reveal diversity from West Indonesia to East Indonesia. Gene amplification was performed using the polymerase chain reaction followed by Sanger sequencing. Based on DNA sequence analysis, we identified three species of Spanish Mackerel available at various fish markets around the region. The first group is related to Scomberomorus commerson, which was sold in both Western and Eastern Indonesian fish markets; the second group is related to Scomberomorus semifasciatus, which was sold in Eastern Indonesian fish markets; and the third group is related to Scomberomorus koreanus, which was sold in Western Indonesian fish markets. The genetic differences amongst Spanish Mackerel populations ranged from 0 to 17% and the average evolutionary divergence in the overall populations was determined to be 4%. The data collected can be utilized to initiate map mackerel diversity based on CYT B sequence throughout the Indonesian Archipelago, as well as for further study and application in the identification of foods produced from mackerel.

Sheep farming in Indonesia has a major challenge of low productivity. The demand of domestic market for sheep is increasing over time. This study aimed to assess the production management systems to improve the livelihood of sheep farming. The method was descriptive with case study in Bangun Karso Farm, Bogor, Indonesia. Data related to farm management were collected in the farm. The description on sheep production was conducted on sustainable farming practices, breeding program and feeding system. The farm keeps fat-tailed sheep (FTS), thin-tailed sheep (TTS), and crossbreed of FTS and TTS with temperate breed. The purposes of sheep farming were fattening and breeding. It has total 374 sheep from various breeds and ages. The sheep that use for breeding were 167 sheep. The result showed that with the current sheep production management system, it is possible to maintain genetic diversity. The study suggests that planned and controlled cross-breeding are important to prevent the dilution of sheep genetic resources.
