The aim of the research was to study the quality of livestock production in relation to carcass quality and body weight. The research was conducted descriptively using exploratory techniques on cattle and their products (carcasses). Research for 1 (one) month at the cattle slaughtering location in Manokwari district, namely the first slaughtering location is Transito Wosi, the second slaughtering location is Rendani and the third location is Wosi Market. Samples were obtained randomly by selecting 86 male cattle which were slaughtered with the following criteria: Age 1-2 years, Age 2-3 years, Age 3-4 years, Age 4-5 years and Age > 5 years. The results of this study indicate that the percentage of cattle slaughtered is based on age, namely 2-3 years of 67.44%, 3-4 years of 43.99%, while the highest carcass weight is in the 3-4 year age category of 162.89 ± 77. 32 kg, and the longest carcass length in the 4-5 year old cattle category was 122.40 ± 11.80 cm. Slaughter weight has a close relationship (94.72%) with carcass weight, carcass percentage and carcass length. Differences in age category had no effect on carcass weight, carcass length and carcass percentage. Body weight is strongly influenced by body length and chest circumference. It is necessary to carry out further research with observations starting from livestock rearing, feed given, livestock handling before to after slaughter, carcass quality (thickness of fat, area of rib eye veins).

No full textAbstract
Bandicoot (Echypera rufescens) is an alternative source of animal protein and a source of germplasm for humans, especially local communities in Papua. These animals are obtained by hunting and/or setting traps in the community's closest habitat. The aim of this research was to determine the relationship between body measurements and body weight and carcass weight by utilizing 32 bandicoots, 16 males and 16 females, with a live weight range of 400 - 2000 grams in Yapen Island Regency, Papua. The study was conducted by using an explorative study and the data were analyzed using multiple correlations and regression. The carcass was obtained by slaughtering the head, removing the blood, and then removing the hair by burning (singeing). The average body weight of male bandicoots was 1403 grams and that of females was 598.75 grams, while the average carcass weights of males and females were 1050.06 grams and 415 grams, respectively. The average heart girth of male bandicoots is 23.03 cm and that of females is 17.81 cm, while the average body length of male and female bandicoots is 25.19 cm and 18.91 cm, respectively. The average percentage of male bandicoot carcasses was 73.99 cm and that of females was 69.22 cm. The correlation coefficient between body weight and body measurements was 0.911 while the carcass weight and body measurements were 0.901. The correlation between body weight and carcass of male bandicoots were 0.911 and 0.901. The correlation between body weight and carcass of female bandicoot were 0.702 and 0.747. The regression equation for male bandicoots to estimate body weight (BB) and carcass weight (BK) were BB = (-1705, 594+84,432 X1 +46,234X2) and (BK = -432,092 +71,545 X1 +33,127X2). The female bandicoot regression equations to estimate body weight (BB) and carcass weight (BK) were: (BB = -509,134+39,437 X1 +21,443X2) and (BK= -436,703 +31,720 X1 +15,164X2).

Bandikut (Echypera rufescens) merupakan salah satu sumber alternatif protein hewani dan sumber plasma nutfa bagi manusia khususnya masyarakat lokal yang berada di Papua. Hewan ini diperoleh dengan cara berburu dan/atau pemasangan jerat di habitat terdekat masyarakat. Penelitian tentang hewan ini bertujuan untuk mengetahui hubungan antara ukuran-ukuran tubuh dengan bobot badan dan bobot karkas dengan memanfaatkan 32 ekor bandikut masing-masing 16 ekor jantan dan 16 ekor betina dengan kisaran berat hidup 400 - 2000 gram. Karkas diperoleh dengan cara bagian kepala disembelih, dikeluarkan darah kemudian dilakukan penghilangan bulu dengan cara dibakar (singeing). Karkas terdiri dari daging, tulang dan lemak setelah kepala, isi rongga dada dan perut, kaki belakang bagian bawah dan kaki depan bagian bawah serta ekor dikeluarkan. Rata-rata bobot badan bandikut jantan adalah 1403 gram dan betina adalah 598,75 gram, sedangkan rata-rata bobot karkas jantan dan betina masing-masing adalah 1050,06 gram dan 415 gram. Rata-rata lingkar dada bandikut jantan adalah 23,03 cm dan betina adalah 17,81 cm, sedangkan rata-rata panjang badan bandikut jantan dan betina berturut-turut adalah 25,19 cm dan 18,91 cm. Rata-rata persentase karkas bandikut jantan adalah 73,99 cm dan betina adalah 69,22 cm. Koefisien korelasi antara bobot badan dengan ukuran-ukuran tubuh adalah 0,911 sedangkan antara bobot karkas dengan ukuran-ukuran tubuh adalah 0,901. Korelasi bobot badan dan karkas bandikut jantan adalah 0,911 dan 0.901. Korelasi bobot badan dan karkas bandikut betina adalah sebesar 0,702 dan 0,747. Persamaan regresi bandikut jantan untuk menduga bobot badan (BB) dan bobot karkas (BK) adalah BB = (-1705, 594+84,432 X1 +46,234X2 dan BK = -432,092 +71,545 X1 +33,127X2.

Condition and Status of Shrimp Fisheries in West Papua Province: Case from Bintuni Bay Regency, Sorong City, and South Sorong Regency
No full textThe aim of this research was to determine the condition and status of shrimp fisheries in Bintuni, Sorong, and South Sorong Regency. This research was conducted from May to July 2019 in the center of the shrimp industry. Variables measured in this study include the status of shrimp fisheries, shrimp fisheries production data for 10 (ten) years, conditions of shrimp availability, size, and type of shrimp obtained through interviews using questionnaires used to obtain an overview of shrimp stock conditions in nature. Analysis of the estimation of potential shrimp resources using the surplus production method from FAO (Food Agriculture Organization). Surplus Production is based on the assumption that Catch per Unit Effort (CPUE) is a function of f (catching effort/effort) which is linear. Data analysis, it was found that the highest number of shrimp catches occurred in 2010-2015, while the status of shrimp fisheries from the maximum sustainable yield (MSY) was 10,943.1 tons per year. Based on data collected for 10 years, from 2010 to 2020, the number of shrimp catches in the waters of Bintuni Bay and South Sorong has not exceeded the value of shrimp sustainable potential. The highest shrimp catch in the waters of Bintuni Bay and South Sorong occurred in 2015, which was 5,473 tons. The utilization rate of shrimp in the waters of Bintuni Bay and South Sorong is 5,473/10,943.1 which is 50.01%, respectively. Based on calculations using the catch effort data analysis package (CEDA 3.0), the value of the catchability coefficient (q), intrinsic growth rate (r), and carrying capacity (k) are used to determine the population growth rate. In equilibrium condition, when the growth rate is equal to zero, the shrimp population is equal to a carrying capacity of 15.519,9 tons per year, respectively
PERAN TERNAK BABI SEBAGAI BIO-TILLAGE SYSTEMS PADA LAHAN KEBUN DALAM BUDAYA BERTANI MASYARAKAT ARFAK, PAPUA BARAT
No full textABSTRAKMengetahui seberapa jauh aplikasi penggunaan ternak babi dalam kebun masyarakat Arfak di Pegunungan Arfak penting untuk dipelajari karena Arfak memiliki kondisi agroekologi penting. Masyarakat Arfak memiliki kearifan dalam bertani serta memiliki hubungan yang dekat dengan ternak babi. Hasil tinjauan di lapang dan referensi menunjukkan bahwa ternak babi relatif masih digunakan pada lahan pertanian atau kebun keluarga masyarakat Arfak sebagai hewan penggembur tanah (soil dozer). Ternak babi, kebun dan masyarakat Arfak saling berinteraksi dengan memberikan peranan kepada masing-masing komponen. Kelebihan ternak babi sebagai penggembur tanah kebun biologis mampu membantu petani orang Arfak. Terdapat 7 keunggulan penggunaan ternak babi dalam kebun. Namun jumlah ternak yang dapat dimasukkan serta sejauhmana kinerja ternak babi dalam setiap luasan lahan secara ekonomis, ekologis dan sosiologis masih harus dikaji secara intensif. ABSTRACTKnowing how far the application of pig farming in Arfak people 's gardens in the Arfak Mountains is important to learn because Arfak has important agro ecological conditions, the Arfak people have wisdom in farming and have a close relationship with pigs. The results of the review in the field and references show that the pigs are relatively still used on agricultural land or Arfak people's family farms as soil dozers. Pigs and gardens and Arfak people interact with each other by providing service to each component. The advantages of pigs as biological gardeners are able to help Arfak farmers. There are 7 benefits of using pigs as bio-tillage inside Arfak household gardens. However, the number of livestock that can be included and the extent to which the performance of pigs in each area of land economically, ecologically and sociologically, must still be studied intensively. Â
