Nowadays, beef cattle farms in Licin Subdistrict, Banyuwangi Regency have problems in providing beef demand because the less of productivity. This problems occured due to the repeat breeding case and decrease the efficiency and productivity of livestock. It suspected because of the lack of hygine and sanitation from farmers and inseminator. This study aimed to correlate the factors and cases of repeat breeding on beef cattle in Licin Subdistrict, Banyuwangi Regency. It was a descriptive study which used 69 cow with simple random sampling method. Primary data was obtained from direct observation of livestock, then continued with interviewing farmers using in-depth study system. While secondary data is obtained from the records of inseminator. It included the term of farming, farmer’s ability to detect estrus cycle, housing and the feeding of beef cattle. The collected data was analyzed by descriptive statistic, then processed by using SPSS 22.0. Chi Square Test (X2) was used to determine the relation between the causal factors and repeat breeding. The results of this study indicate the prevalence of repeat breeding in Licin Subdistrict, Banyuwangi Regency by 64%. All the factors such as the term of farming, farmer’s ability to detect estrus cycle, and feeding of beef cattle are correlated with the incidence of repeat breeding.
Soil substrate merupakan media tanam sebagai media tanam dan bersentuhan langsung dengan akar tanaman air. Bentuk yang umum adalah granula, karena lebih mudah ditaburkan dan meresap ke tanaman. Tujuan penelitian adalah untuk mengetahui hasil optimal rasio perekat molases dan bahan baku yang tepat untuk mendapatkan granula media tanam yang tidak mudah hancur saat pengaplikasian di air dan perubahan nilai pH air. Proses yang digunakan yaitu granulasi basah, dilakukan dengan mencampurkan bahan baku serbuk dengan perekat kemudian dilakukan pengeringan dan pengayakan. Variasi rasio tanah humus dan tanah tanam yaitu 1:3, 2:3 dan 3:4. Variasi rasio molases dan air yaitu 20 mL:400 mL, 30 mL:400 mL dan 40 mL:400 mL. Hasil optimal menggunakan perekat molases 20 mL pada rasio bahan 1:3 dan 2:3 mampu mempertahankan bentuk 7 hari. Pada molases 30 mL dan rasio bahan 1:3 mampu bertahan 2 hari. Dan pada molases 40 mL dengan rasio bahan 1:3 mampu bertahan 2 hari, namun rasio bahan 2:3 mampu bertahan 7 hari. Kualitas fisik optimal yang dihasilkan yaitu dengan perekat molases 20 mL pada rasio bahan 1:3 dan 2:3, dan perekat molases 40 mL dengan rasio bahan 2:3. Nilai pH mengalami penurunan dalam 5 hari pertama, namun meningkat pada hari ke 6 dan 7 dikarenakan konsentrasi CO 2 dan suhu air. Hasil penelitian menunjukkan bahwa rasio air dan perekat yang digunakan, rasio bahan baku yang digunakan sangat mempengaruhi ketahanan soil substrate dan pH air yang dihasilkan saat diaplikasikan di dalam air.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
