ABSTRAKTujuan penelitian ini adalah untuk mengevaluasi peningkatan genetik sifat-sifat produksi pada sapi Bali. Sebanyak 428 data bobot sapih, bobot setahun dan pertambahan bobot badan digunakan untuk menduga peningkatan genetik sifat-sifat tersebut. Seratus tujuh data ukuran tubuh (bobot badan, lingkar dada, panjang badan dan tinggi gumba) pada umur 24 bulan juga digunakan untuk menduga peningkatan genetiknya. Pendugaan komponen ragam dan peragam genetik, dan heritabilitas diperoleh dengan menggunakan animal model. Pengaruh tetap untuk bobot sapih, bobot setahun dan pertambahan bobot badan adalah curah hujan, umur pengukuran dan tahun kelahiran, sementara pengaruh tetap untuk ukuran-ukuran tubuh tergantung dari masing-masing karakter. Hasil penelitian menunjukkan bahwa heritabilitas bobot sapih, bobot setahun, pertambahan bobot badan, bobot badan, lingkar dada, panjang badan dan tinggi gumba berturut-turut adalah 0,09±0,15; 0,27±0,13; 0,47±0,15; 0,07±0,19; 0,50±0,19; 0,34±0,28 dan 0,60±0,21. Peningkatan genetik untuk semua karakter mempunyai pola yang berbeda dalam merespon seleksi. Semua karakter tidak menunjukkan peningkatan genetik akibat seleksi.Kata kunci: Sapi Bali, peningkatan genetik, seleksi, karakter produksi ABSTRACTThe aim of the research was to evaluate the genetic improving of production traits selected of Bali cattle. Four hundred and twenty eight data of weaning weight, yearling weight and body weight gain were used to estimate genetic improvement for those traits. One hundred and seven data of body dimension (body weight, chest circumference, body length and withers height) at 24 months old were used to estimate genetic improving for those traits. The estimation of genetic and environmental variance and co-variance component, and heritability were found by animal model. The fix effect of weaning weight, yearling weight and body weight gain was rainfall, age of measurement and year of birth, whereas the fix effect of body dimension depend on each trait. The result showed that heritability of weaning weight, yearling weight, body weight gain, body weight, chest circumference, body length and withers height was 0.090.15, 0.270.13, 0.470.15, 0.070.19, 0.500.19, 0.340.28, 0.600.21, respectively. Genetic improvement of all traits have had a different pattern in selection responses. All traits did not show genetic improvement due to selection for.

This study aims to obtain an overview of the performance of Corporate Social Responsibility in Teluk Bintuni Regency in the social, economic, agricultural and environmental fields. Measurement of CSR performance is carried out by examining the gap between the level of importance and the performance of CSR implementation, as well as the priorities needed for program sustainability. There were 40 beneficiaries as respondents, located in the villages of Onar Baru, Onar Lama, Saengga, Tanah Merah, Tofoi, Babo and Bintuni. Data were analyzed using Importance Performance Analysis (IPA). The findings show that the level of conformity between interests and performance is 67%, and from the 14 attributes of the assessment, there are 7 attributes of program management that must be prioritized, namely planning and implementing programs that are as expected, accompanied by clear monitoring and evaluation. The program must be in accordance with the objectives, provide opportunities for the community for community involvement to provide input and have an orientation to the satisfaction of the target community.

Abstrak  Sistem pengelolaan adalah faktor penting untuk meningkatkan produktivitas ayam lokal.  Penelitian ini bertujuan untuk melihat sistem pengelolaan ayam buras yang dilakukan oleh peternak Masyarakat Asli Papua (IP) dan Non-Papua (NIP) di Kabupaten Manokwari Utara.  Dua puluh peternak baik IP maupun NIP dipilih secara purposive sebagai responden.  Metode analisis yang digunakan adalah metode deskriptif.  Pengumpulan data primer dilakukan dengan wawancara dan observasi lansung di lapangan.  Wawancara dilakukan dengan menggunakan kuesioner terbuka dan tertutup.  Data yang terkumpul kemudian ditabulasi, dianalisis, dan kemudian dinarasikan untuk dapat menarik suatu kesimpulan.  Hasil penelitian menunjukkan bahwa sistem pengelolaan ayam buras yang dilakukan oleh peternak IP dan NIP hampir sama dan hampir semua paremeter masih dalam standar normal.  Namun, beberapa data produksi dan reproduksi tidak dapat diperoleh karena tidak adanya pencatatan data.  Kesimpulan, sistem pengelolaan ayam buras yang dilakukan oleh peternak Papua dan Non-Papua di Kabupaten Manokwari Utara masih memerlukan pembinaan terutama dalam pencatatan data produksi dan reproduksi.  Dukungan pemerintah berupa pelatihan melalui penyuluh pertanian sangat diperlukan dalam rangka meningkatkan pengetahuan peternak tentang sistem pengelolaan ayam buras.  Dukungan motivasi berupa bantuan dana dari pemerintah juga diperlukan untuk mengembangkan peternakan ayam kampung untuk menunjang perekonomian para peternak khususnya di Kabupaten Manokwari Utara.

The interview was done by using an open and closed questionnaire.  Data collected were then tabulated, analyzed, and then narrated to draw a conclusion.  The results showed that the management systems of native chickens carried out by the IP and the NIP farmers were similar and almost all parameters were still in the normal standard.  However, some production and reproduction data were not able to get due to no data recording.  In conclusion, the management system of native chickens carried out by Papuans and Non-Papuans farmers in the North Manokwari District still requires guidance, especially in recording production and reproduction data.  Government support in the form of training through agricultural extension agents is needed in order to improve farmers knowledge of native chickens management systems.  In addition, motivational support from the government is needed to develop native chicken farms to support the farmers’ economy, especially in the North Manokwari District.  Keywords: Financial assistance; Indigenous Papuan farmers; Training support

The performance of Bali cattle in the production of meat has not been maximal. The purpose of the research was to 1). Study potential of Bali bull through breeding value; 2). Analyze of direct and indirect selection response. A total of 1,284 data of weaning weights, yearling weights and body weight gain from 99 cows with 2-7 records were used to analyze the breeding values of bull and selection responses. Estimation of variance and co-variance components of genetic and environmental, and heritability is obtained using the Variance Component Estimation program. PEST program is used to estimate breeding value of bull. Selection response is estimated based on heritability, standard deviation and selection intensity. The results showed that of 28 bulls tested, 53.57% had a positive breeding value of weaning weight; 42.86% had a positive breeding value of yearling weight and 53.57% had a positive breeding value of body weight gain. The direct selection response of weaning weight, yearling weight and body weight gain were 0.26 kg, 1.17 kg and 0.38 kg, respectively, whereas the indirect selection response of weaning weight-yearling weight and weaning weightbody weight gain were 0.21 kg and 0.04 kg respectively.

Weaning weights and yearling weights are economical characteristics of production to be used as selection criteria in animal. The study aimed to evaluate selection response of weaning weight and yearling weights directly and to evaluate selection response of yearling weights indirectly through weaning weights. A total of 190 data from 23 sires and 133 dams were used to estimate the heritability of weaning weights. Data to estimate heritability of yearling weights were about 231 data from 20 sires and 101 dams. Data to estimate genetic correlation between weaning weights and yearling weights were about 194 data from 26 sires and 125 dams. The heritability was estimated by using a variance analysis of paternal half-sib correlation. The results showed that heritability of weaning weights and yearling weights were 0.63±0.291 and 0.68±0.342, respectively. The genetic correlation between weaning weights and yearling weights was 0.78. The fewer proportions of animal that selection for, the higher selection response for weaning weights and yearling weights both directly and indirectly selection.
