Karakteristik Peternak Sapi di Sentra Produksi Ternak Potong Di Kabupaten Sorong

The development of beef cattle needs to be supported by regional potential which includes natural resources and human resources. Sorong Regency is one of the areas for beef cattle development in West Papua Province. This research was conducted for three months, from February to April 2021. The study was conducted in four districts that have a high population of beef cattle in Sorong Regency, West Papua Province. namely Salawati District, Segun District, Mayamuk District, and Moisegen. This research was conducted using a survey method with interview techniques and field observations. Breeding experience, education, age have a relationship with the number of livestock kept. The result showed that farmers were in the productive age and had low education. The traditional rearing with extensive system was a common management practice with less than six cows per household. The experience of rearing cattle, age and education had a correlation with number of cows per household (r<0.05). However, there was not very strong relationship with the variable number of beef cattle. The land area factor does not affect the number of livestock and education was not influence management system. It concluded that livestock activity purposed was not up to business level but it was only for saving purposes.

Kabupaten Sorong merupakan salah satu wilayah pengembangan ternak potong di Provinsi Papua Barat. Penelitian dilakukan di empat distrik yang memiliki populasi ternak sapi potong yang cukup tinggi di Kabupaten Sorong Provinsi Papua Barat. yaitu Distrik Salawati, Distrik Segun, Distrik Mayamuk, dan Moisegen, pada bulan Februari sampai dengan April 2021. Penelitian ini dilakukan menggunakan metode survei dengan teknik wawancara dan observasi lapangan. Kriteria responden pada penelitian ini adalah memiliki sapi > 3 ekor dan memiliki pengalaman beternak lebih dari 3 tahun. Penentuan jumlah sampel menggunakan rumus Slovin. Hasil penelitian menunjukkan bahwa karakteristik peternak antara lain: berada pada usia produktif, memiliki pendidikan yang cukup rendah, pengalaman beternak yang cukup lama dan tingkat kepemilikan ternak yang rendah. Sistem pemeliharaan ternak bersifat tradisional dengan pemberian pakan dan pengobatan seminimal mungkin. Pengalaman beternak, pendidikan, umur memiliki hubungan dengan jumlah ternak yang dipelihara. Hal ini ditunjukkan dengan nilai koefiesien korelasi r= (r <0.05). Pengalaman beternak dan pendidikan memiliki keeratan hubungan yang tidak terlalu kuat terhadap variabel jumlah ternak sapi potong. Faktor luas lahan tidak mempengaruhi jumlah ternak yang dipelihara. Hal ini dikarenakan sistem pemeliharaan yang dilakukan peternak dominan dengan sistem umbar terbatas dan pemberian pakan ditambah dari sumber lain seperti pinggir jalan dan sumber lain. Faktor luas lahan tidak mempengaruhi jumlah ternak yang dipelihara. Berdasarkan hasil penelitian ini dapat disimpulkan bahwa peternak di sentra peternakan sapi Kabupaten Sorong masih bersifat tradisional yang bertujuan untuk tabungan keluarga dan secara umum belum berorientasi bisnis.

Tree Biomass Estimation in Karst Forest of West Papua, Indonesia

Indonesia is estimated to have 14,5 million hectares of karst areas. The characteristic of karst vegetation is specific, one of which is the dominance of small trees. With all of the potency, their vegetation acts as a significant carbon sequester and store it in biomass. This study aims to estimate and discuss biomass estimation in the karst forest within the Nature Recreational Park of Beriat, a protected area in South Sorong, West Papua. A total of 28 plots were made in the forest using the purposive random sampling method. Tree biomass (DBH ≥10 cm) was estimated using five different allometric equations. The results showed that the biomass was estimated at ca. 264 Mg ha-1 (95 % CI: 135-454 Mg ha-1). While small trees (DBH 10 – 30 cm) only contribute 30 % of the total biomass, about 38 % of the biomass is the contribution of large trees (DBH >50 cm), where Pometia pinnata contributes ca. 39 % of the biomass at plot-level. The use of various allometric equations results in different biomass estimates and biases with deviations ranged from -14.78 % to +17.02 % compared to the reference equation. Therefore, the selection of allometric equations used must be considered carefully to reduce uncertainties in biomass estimation.

“Move backward to make a step forward”: Understanding the migration of the highly educated to Sorong City, West Papua, Indonesia

Highly educated people are mainly concentrated in big cities or metropolitan areas. However, some of them choose to move to less developed regions. Using information from in-depth interviews of 15 highly educated migrants that recently moved to Sorong City, a small city in easternmost Indonesia, this study examines the narratives behind their spatial movements. The findings show that promising career development is a critical factor in their migration decision-making process. Although most of them faced difficulties with the limited living amenities in Sorong city, the migrants managed to improve their employability and accelerate their social mobility. However, some migrants expressed their intentions to remigrate from the city in the future. This situation indicates the lack of migrants’ social integration and the challenges in the human capital accumulation in the region.

Religious Moderation and Information Communication Technology Dissemination: The Practice of Muhammadiyah Papua Through Online Campaign

This article contains the efforts made by Muhammadiyah universities in Papua and West Papua related to religious moderation campaigns through information technology. There are at least three things that form the basis for the birth of this study: 1) the speed of the radicalism movement over which religion exists in the digital world; 2) potential for conflict and SARA, especially in Papua and West Papua 3) the importance of strengthening religious moderation in Indonesia, especially through digital media. The method used is library research, namely by exploring various literatures, both primary and secondary, related to the concept of religious moderation in Indonesia. The results of the study show that Muhammadiyah Papua universities in campaigning for religious moderation function as a counterweight in the digital world. That is, the narrative of religious moderation from the Muhammadiyah Papua university gave birth to a substantive and essential religious framing that is moderate and tolerant.

Genetic structure and phylogenetic relationships of Phyllidiellapustulosa species from Seribu Islands, North Sulawesi, Halmahera, and West Papua

Phyllidiella pustulosa are brightly coloured gastropod molluscs frequently found in coral reefs of the tropical Indo-Pacific. Phyllidiella pustulosa is widely distributed in Indonesia, such as Seribu Island, North Sulawesi, West Papua, and Halmahera. Based on the genetic characteristics of an individual’s DNA sequence, differences between species can be identified. In this paper, we would like to provide the molecular analysis and phylogenetic relationship among nudibranchs from Indonesian waters. Identification was made by measuring the genetic distance between species. The phylogenetic tree reconstruction was made using the Kimura 2-parameter model with 1000 times bootstrap with neighbor-joining and maximum likelihood method. There is 46 DNA Sequence obtained from 4 different regions (Seribu Island, Halmahera, North Sulawesi, and West Papua). The genetic distance of West Papua and Halmahera has the smallest value among other populations, which is between 0.0051-1.4629, compared to the population in Halmahera. The phylogenetic tree also shows populations from West Papua and Halmahera are on the same lineage, indicating that the population in West Papua and Halmahera had the closest relation. The study suggested that North Sulawesi, Halmahera and West Papua have genetic mixing of the same region, which is distinctive from Seribu Island.
