Nowadays, supply chain management is vital for palm oil plantations, along with the increases of competitive efforts and equal partnership position between suppliers and processors. The research aimed at mapping supply chain patterns of palm oil plantation, at analyzing performances of palm oil stakeholders, and at analyzing factors influencing performances of stakeholders in the province. The research was conducted using survey method by interviewing and focus group discussion. The results showed that (1) there were 3 supply chains flows from bunches of palm fruit to plants of palm fruit processing; (2) roles of stakeholders in supply chain management determining supply volumes, profits, and value added; and (3) factors influencing performances of stakeholders and competitive advantages were plantation productivity, cost allocation for invesment and operation, capacity of processing plants, and CPO rendemen rate.
Antioxidants such as tocopherol, ß-carotene, and polyunsaturated fatty acids (PUFA) from red fruit oil of Papua may be used to protect frozen semen. The study is aimed to test the effect of red fruit oil supplementation on motility, viability, and recovery rate of frozen sperm of Ongole-grade bulls. Semen was collected twice a month from eight 4-5-year-old male Ongole grade using an artificial vagina, followed by macro- and microscopical evaluations. Collected semen was divided into four tubes and diluted with tris egg yolk diluents (TEY) as a control, TEY supplemented with 0.5% red fruit oil (RFO) (TEY RFO0.5), TEY supplemented with 1% RFO (TEY RFO1.0), and TEY supplemented with 1.5% RFO (TEY RFO1.5). The diluted semen was then packed into the straw and equilibrated for 2, 4, and 6 h prior to frozen on liquid nitrogen vapor for 10 minutes. The observed variables in this study were sperm motility, sperm viability, and morphology after equilibration, after thawing, and recovery rate. The experimental design is a completely randomized factorial design. The data were analyzed using ANOVA and were further tested using Duncan multiple range test. The results showed that the sperm motility of fresh semen was 81.10±1.42%. The percentage of sperm motility in TEY RFO1.5 treatment at 6 h equilibration was 60.00±1.06%, significantly higher compared to TEY RFO1.0 and TEY RFO0.5. The percentage of post-thawing sperm motility in TEY RFO1.5 treatment was 62.40±1.09%. The best post-thawing sperm viability in TEY RFO1.5 was 80.70±1.20%, significantly increase from the treatment of TEY RFO1.0 and TEY RFO0.5. The recovery rate (RR) for TEY RFO1.5 treatment had the best percentage at 76.94%. In conclusion, RFO supplementation in semen diluents for 2 h of equilibration resulted in the best motility and viability at 0 h of post thawing observation.
Ketersediaan bibit domba garut unggul jumlahnya relatif sedikit serta belum tersedia pasokan domba bibit jantan unggul yang produksinya tinggi secara berkesinambungan. Keberhasilan kriopreservasi semen dipengaruhi oleh bahan pengencer yang digunakan. Penelitian ini bertujuan untuk membandingkan pengencer Tris Kuning Telur mengandung omega-3 (TKTO) dan Tris menggunakan kuning telur komersial ditambah omega-3 minyak ikan salmon (TKTOS) terhadap keberhasilan kriopreservasi semen domba garut. Sebanyak lima ekor domba garut jantan berumur 1,5-2,0 tahun digunakan sebagai sumber semen. Semen dikoleksi menggunakan vagina buatan, dievaluasi dan dibagi dua, masing-masing diencerkan menggunakan TKTO dan TKTOS dengan dosis 50 juta/straw. Selanjutnya dikemas dalam straw, diekuilibrasi 5 o C, dan dibekukan dalam uap nitrogen cair (-130 o C) selama 10 menit dan disimpan pada kontener (-196 o C) untuk pengujian lebih lanjut. Hasil penelitian semen post thawing menunjukkan bahwa motilitas, viabilitas, dan membran plasma utuh spermatozoa masing-masing 53,75±2,46; 60,75±2,17; 72,58±2,12% dalam pengencer TKTOS, lebih tinggi (P<0,05) bila dibandingkan dengan spermatozoa yang diencerkan dengan TKTO dengan nilai motilitas, viabilitas dan membran plasma utuh masing-masing 41,50±1,25; 50,50±1,04 dan 57,58±1,03%. Nilai tersebut menunjukkan recovery rate spermatozoa domba garut dalam pengencer TKTOS lebih tinggi (P<0,05) dibandingkan TKTO. Simpulan dari penelitian ini adalah omega-3 minyak ikan salmon yang ditambahkan dalam pengencer TKTOS dapat meningkatkan keberhasilan pembekuan semen domba garut lebih baik bila dibandingkan dengan pengencer TKTO.
The purpose of this study was to identify and analyze the influence of destination image, tourist attraction, and experience of climbers on intention to return with satisfaction as an intervention variable for climbers of Mount Gede Pangrango. Instruments used in this research were questionnaires to 150 respondents with descriptive and quantitative data processing and analysis. Descriptive analysis in the research aims at describing the characteristics of the respondents and describing the research variables, while quantitative analysis is carried out using SEM - PLS (Partial Least Square) tools with the aim of testing the hypothesis. Based on the results of the analysis in this study, it can be explained that the image of the destination, tourist attraction, and experience of climbers has a positive and significant effect on satisfaction among climbers of Mount Gede Pangrango. Destination image, tourist attraction, climber experience, and satisfaction have a positive and significant effect on intention to return to climbers of Mount Gede Pangrango. Travel image, tourist attraction, and climber experience have a positive and significant effect on Repeat Visit Interest with Satisfaction as an intervention variable for climbers of Mount Gede Pangrango.
Potensi merauke sebagai daerah penghasil sapi potong di kawasan timur Indonesia telah di tetapkan oleh pemerintah, namun perlu adanya kajian lebih lanjut tentang kemampuan produksi dan reproduksi sapi lokal yang tolerans terhadap iklim di merauke. Tujuan dari penelitian ini adalah untuk mengetahui performas reproduksi sapi lokal di merauke, dewasa kelamin, umur pertama kawin, siklus birahi, lama estrus, lama kebuntingan, kawin kembali setelah beranak dan calving interval. Metode yang digunakan adalah survei secara langsung dan wawancara pada peternak. Data primer diperoleh dari dinas peternakan dan kesehatan hewan kabupaten merauke, sedangkan data sekunder di peroleh dari hasil wawancara dengan inseminator. Data diolah secara statistik menggunakan analisis deskriptif dalam bentuk rata-rata dan standar deviasi dari setiap peubah yang diamati. Pengambilan sampel dilakukan dengan cara purposive sampling menggunakan sapi sebanyak 90 ekor. Hasil analisis menunjukkan performans reproduksi pada sapi jantan (pubertas) 17,20±0,066 bulan, umur pubertas sapi betina 20.90±0,099 bulan, umur sapi dara pertama kali dikawinkan 24.50±0,008 bulan. Lama bunting anak jantan 278,33±0,011 hari, lama bunting anak betina 274.10,33±0,044 hari. Kawin kembali setelah beranak 129,67±0,397 hari, nilai S/C sapi lokal >1 namun dalam ambang batas normal dan tingkat kematian pedet mencapai 18,04% yang diakibatkan oleh faktor eksternal. Kesimpulan penelitian ini adalah Performa reproduksi pada sapi lokal di merauke dengan keadaan suhu tinggi dalam keadaan normal.
