Comparative Study of Milk Production and Feed Efficiency Based on Farmers Best Practices and National Research Council

This study aimed to compare local dairy farmer ration formula with national research council in producing higher feed efficiency and milk production. This study had two stages. The first stage was in vitro study of dairy farmer rations which have different raw materials (R3, R4, and R5) with NRC based ration (R2) and Demo Farm ration (R1). The variables measured in this stage were proximate composition, volatile fatty acid, ammonia, dry matter and organic matter digestibility. The first stage used a randomized block design with five treatments, three groups of ruminal fluid, and three replications. The second stage used nine lactating cows with three periods of lactation (one, three, and other) and used a randomized block design with three treatments, three groups, and one replication. Parameters measured were dry matter intake, manure score, milk production, body weight gain, body condition score, and technical and economical efficiencies. The first stage result showed that R1, R2, and R3 were three best rations in nutrient composition and fermentability (ammonia and volatile fatty acid concentrations were optimum for microbial growth and high digestibility), so in conclusion those three rations were the best rations and should be compared by in vivo method. The result of the second stage showed that all tested rations were not significantly different in milk production, performance and efficiency, so in conclusion those three rations have the same quality

Production, Competition Indices, and Nutritive Values of Setaria Splendida, Centrosema Pubescens, and Clitoria Ternatea in Mixed Cropping Systems in Peatland

This research was conducted to evaluate production, different competition indices and nutritive value of Setaria splendida, Centrosema pubescens, and Clitoria ternatea in monoculture and mix cropping system on peat soil land. The experiment was set up in a randomized complete block design with five treatments and three replications. The five treatments were: S. splendida sole cropping (SS), C. pubescens sole cropping (CP), C. ternatea sole cropping (CT), S. splendida and C. pubescens mix cropping (SS/CP) and S. splendida/C. ternatea mix cropping (SS/CT). The DM yield of S. splendida in mixed cropping with C. pubescens increased 43.4% and in mix cropping with C. ternatea increased 15.7% compared to sole S. splendida. The value of land equivalent ratio of SS/CP (LERSS/CP) was >1. The LERSS/CT value was <1. The crowding coefficient value of S. splendida (KSS) was higher than KCP and KCT. The total value of KSS/CP and KSS/CT were >1. The competition ratio (CR) values of S. splendida in both mix cropping were >1. The agressivity (A) values of S. splendida in both mix cropping were positive. The crude protein, NDF and ADF content of forage were not affected by mix cropping system. In conclusion, mix cropping in peatland do not affect productivity and nutritive value of S. splendida, C. pubescens, and C. ternatea. S. splendida is more effective in exploiting environmental resources when intercropped with C. pubescens compared to C. ternatea on peatland

The Main problems in this study: first, how legal reasoning of civil law and Islamic law on sex change operation confusion, especially those transsexual patients. The Main problems in this study: first, how legal reasoning of civil law and Islamic law on sex change operation transsexual patients. Second, where is the difference transsexual patients. Second, where is the difference between civil law and legal reasoning of Islamic law on sex-change operation transsexual patients. between civil law and legal reasoning of Islamic law on sex-change operation transsexual patients

Penerapan Metode Pembelajaran Aktif Cooperative Script untuk Meningkatkan Prestasi Belajar Siswa pada Pokok Bahasan Struktur Atom di Kelas X Mia SMA Negeri 1 Kepenuhan Kabupaten Rokan Hulu

Research on the application of active learning Cooperative Script method has been done in class X of SMAN Kepenuhan Kabupaten Rokan Hulu on the subject of atomic structure. Based on the results of observations conducted by researchers at the SMAN1Kepenuhan Kabupaten Rokan Hulu do known that learning is teacher centered, so that students become less active and negatively affect student achievement. The objective was to determine the increase in student achievement and increase student achievement category. The research form is an experimental research with pretest-posttest design. The sample consisted of two classes, namely class X MIA1 as the experimental group and the class X MIA2 as the control group. The experimental group is the group of students who were treated by applying the active learning of Cooperative Script method, while the control group was treated with information discussion methods. Data analysis technique used is the t-test. The results showed tarithmetic>ttable (2,07 > 1,68) and N-gain of the experimental group is 0,754 which includes the high category. Therefore, it can be concluded that the application for active learning Cooperative Script method can increase student achievement in the subject of anatomic structure in SMAN 1 Kepenuhan Kabupaten Rokan Hulu

Peran Lembaga Peutua Uteun (Panglima Hutan) Dalam Melestarikan Hutan Di Pedalaman Kecamatan Geumpang Kabupaten Pidie

Penelitian ini bertujuan untuk mengetahui bagaimana pemanfaatan lembaga adat petuah uteun (panglima hutan) dalam pelestarian hutan di Kecamatan Geumpang Kabupaten pidie. Penelitian ini dilaksanakan di Kecamatan Geumpang Kabupaten Pidie. Penelitian menggunakan metode deskriptif yaitu teknik wawancara (deeply interview), observasi (direct observation) dan dokumentasi. Hasil penelitian menunjukkan bahwa peranan Peutuah uteun dalam pelestarian hutan belum maksimal karena kurangnya kedasadaran dari masyarakat dan juga kerjasama dari pihak pemerintah setempat dalam mengupaya pelestarian hutan. Upaya peningkatan pelestarian hutan melalui peranan Peutua Uteun dengan merangkul dan bermit­ra dengan masyarakat dalam melaksana­kan pengelolaan hutan sehingga kelestarian hutan menjadi meningkat. Hasil observasi hutan di wilayah Geumpang sudah tergolong baik, terlihat dari wilayah permukiman masih terdapat hutan lindung yang sangat alami. Dari pengamatan tersebut tidak terdapat illegal logging dari Perusahaan atau HPH di wilayah Geumpang. Keberadaan Peutua Uteun (panglima hutan) merupakan salah satu ujung tombak dalam menjaga kelestarian hutan. Kata kunci : Petua uteun (Panglima Hutan), Pelestarian Hutan
