The Effect of Fermented Oil Palm Fronds in Diet on Body Weight Gain and Meat Quality of Goat

The aims of study were to evaluate the use of fermented of oil palm fronds (FOPF) on body weightgain and meat quality of goat. This experiment was arranged in Completely Randomized Design with 3treatments i.e. R1 (grass 0%: FOPF 100%), R2 (grass 50%: FOPF 50%) and R3 (grass 100%: FOPF 0%)and 5 replications. The parameters of the study were feed intake, average daily gain (ADG), weight andpercentage of carcass and meat quality. The results indicated that feed intake and meat quality of goatwas not affected by treatment, but the average daily gain, carcass weight, and percentage of carcass, wasaffected by the differences of percentage of FOPF in the pellet complete feed. The best ration was in theR1 ration (grass 0%: FOPF 100%) that significantly different (P<0.05) from the other rations. The feedintake tended to be higher in goat fed R1 (895.87 g/d) compared to those in goat with the R2 (854.38g/d) and R3 (851.53 g/d). The average daily gain and carcass weight were higher in goat fed R1 rationcompared to those in goat fed R2 and R3. Consequently, the carcass percentage in R1 was higher thanthose in R2 and R3. The carcass percentage was ranged from 38.41-41.38%. The Ribeye area was higherin goat fed R1 (9.73 cm2) than R2 (8.34 cm2) and R3 (7.76 cm2). In this study, the protein content ofgoat meat was ranged from 19.06 to 20.71%, lipid content was ranged from 0.703 to 1.106% and watercontent was range from 72.45% to 74.12%, in which were not different among the treatments. It can beconcluded that the use of FOPF in a complete feed could improve performance and meat quality of goat

A model for ranking and selecting integrity tests in a distributed database

Checking the consistency of a database state generally involves the execution of integrity tests on the database, which verify whether the database is satisfying its constraints or not. This paper presents the various types of integrity tests as reported in previous works and discusses how these tests can significantly improve the performance of the constraint checking mechanisms without limiting to a certain type of test. Having these test alternatives and selecting the most suitable test is an issue that needs to be tackled. In this regard, the authors propose a model to rank and select the suitable test to be evaluated given several alternative tests. The model uses the amount of data transferred across the network, the number of sites involved, and the amount of data accessed as the parameters in deciding the suitable test. Several analyses have been performed to evaluate the proposed model, and results show that the model achieves a higher percentage of local processing as compared to the previous selected strategies

Manajemen Laboratorium Biologi Beberapa SMA Swasta di Kota Jambi

Keberadaan laboratorium di sekolah sangat penting dalam menunjang kegiatan belajar mengajar biologi. Adanya laboratorium diharapkan proses pengajaran IPA dapat dilaksanakan seoptimal mungkin. Setiap laboratorium di sekolah sudah seharusnya memiliki manajemen laboratorium yang baik, agar kegiatan praktikum dapat terlaksana dengan lancar. Penelitan ini bertujuan untuk menganalisis manajemen laboratorium biologi yang telah dilakukan oleh pengelola laboratorium beberapa SMA Swasta di Kota Jambi.Jenis penelitian yang digunakan adalah penelitian kualitatif dan menggunakan analisis deskriptif.Subjek penelitian ini adalah kepala laboratorium dan guru biologi beberapa SMA swasta di Kota Jambi. Sekolah-sekolah tersebut adalah sekolah yang berakreditasi A (SMA Xaverius 1, SMA Xaverius 2, SMA Ferdy Ferry Putra, SMA Unggul Sakti, dan SMA Nusantara) dan berakreditasi B (SMA Islam Al-Falah, SMA Yadika, SMA Dharma Bhakti 4, SMA Adhyaksa 1, SMA Dharma Bhakti 3, dan SMA PGRI 2) yang ditetapkan tahun 2011. Teknik pengumpulan data yang digunakan yaitu observasi, wawancara, dan dokumentasi. Lembar observasi alat dan bahan praktikum biologi menggunakan skala bertingkat (rating scale).Setelah itu observasi, wawancara serta dokumentasi dianalisis secara deskriptif. Hasil penelitian menunjukkan bahwa dari empat indikator manajemen laboratorium (perencanaan, pengorganisasian, pelaksanaan, dan pengawasan) dengan 29 rincian dapat dilihat bahwa manajemen laboratorium biologi di tujuh SMA swasta di Kota Jambi yang telah diteliti belum terlaksana dengan baik. Dari tujuh sekolah tersebut, manajemen laboratorium biologi yang terbaik yaitu SMA Yadika dengan memenuhi 18 dari 29 rincian yang ada. Berdasarkan hasil penelitian disarankan setiap sekolah, laboratorium biologinya harus memiliki manajemen laboratorium yang baik agar kegiatan praktikum dapat terlaksana dengan efektif dan efisien, karena alat dan bahan laboratorium yang lengkap belum tentu dapat berfungsi dengan baik jika tidak didukung oleh manajemen yang baik. Selain itu, laboratorium juga harus memiliki teknisi dan laboran, karena peran teknisi dan laboran sangat dibutuhkan untuk membantu tugas kepala laboratorium dalam memanajemen laboratorium

Pengaruh Pemberian Pupuk Kandang Kerbau Dan Dosis Pupuk Anorganik Terhadap Hara N, P, K Tanah, Pertumbuhan Dan Produksi Bawang Merah (Allium Ascalonicum L.)

Penelitian ini bertujuan untuk mengevaluasi hara N, P, K tanah, respon pertumbuhan dan produksi tanaman bawang merah varietas Medan terhadap pemberian pupuk kandang kerbau dan dosis pupuk anorganik di Desa Unjur Kecamatan Simanindo Kabupaten Samosir dan analisis tanah dilakukan di Laboratorium PT Nusa Pusaka Kencana, Tebing Tinggi. Penelitian ini dilaksanakan pada Januari sampai April 2016. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Kelompok (RAK) 2 faktor yang terdiri dari 2x5 taraf yaitu K0 (0 ton/ha pupuk kandang kerbau), K1 (15 ton/ha pupuk kandang kerbau), P0 (0 kg/ha NPK, 0 kg/ha ZA, 0 kg/ha KCl), P1 (65 kg/ha NPK, 65 kg/ha ZA, 15 kg/ha KCl), P2 (130 kg/ha NPK, 130 kg/ha ZA, 30 kg/ha KCl), P3 (195 kg/ha NPK, 195 kg/ha ZA, 45 kg/ha KCl), Px (800 kg/ha NPK, 400 kg/ha ZA, 0 kg/ha KCl) dengan jumlah ulangan sebanyak 3 ulangan. Hasil penelitian menunjukkan bahwa pemberian pupuk kandang meningkatkan panjang tanaman, bobot basah umbi dan bobot kering umbi bawang merah. Pemberian pupuk anorganik meningkatkan hara N dan P tanah, akan tetapi pada dosis tinggi, semakin tinggi dosis pupuk anorganik yang diberikan dapat menurunkan hasil produksi bawang merah. Produksi tertinggi terdapat pada perlakuan K1P1 (15 ton/ha pupuk kandang kerbau, 65 kg/ha NPK, 65 kg/ha ZA, 15 kg/ha KCl)
