Nutrient Digestibility and Productivity of Bali Cattle Fed Fermented Hymenachne Amplexia­calis Based Rations Supplemented with Leucaena Leucocephala

An experiment was conducted to study the effects of lamtoro (Leucaena leucocephala) leaf supplementation in fermented kumpai grass (Hymenachne amplexia­calis) based rations on the productivity of Bali cattle. Variables measured were dry matter and organic matter intakes, nutrient digestibility (dry matter, organic matter, crude protein, and crude fiber), body weight gain, and feed efficiency. The types of rations were: Ration A= 45% fermented kumpai grass + 40% benggala grass + 15% concentrate + 0% lamtoro leaf, Ration B= 45% fermented kumpai grass + 30% benggala grass + 15% concentrate + 10% lamtoro leaf, Ration C= 45% fermented kumpai grass + 20% benggala grass + 15% concentrate + 20% lamtoro leaf, and Ration D= 45% fermented kumpai grass + 10% benggala grass + 15% concentrate + 30% lamtoro leaf. The supplementation of lamtoro leaf up to 30% into the ration could increase (P<0.05) dry matter and organic matter intakes, and crude protein digestibility. The highest body weight gain and feed efficiency were found in Bali cattle fed ration with 20% lamtoro leaf supplementation. The level of lamtoro leaf supplementation in the ration did not affect the digestibility of dry matter, organic matter, and crude fiber. It was concluded that the supplementation of lamtoro leaf in the ration could increase dry matter, organic matter, and crude protein intakes. Addition of 20% lamtoro leaf gave the best effect on the increased body weight gain and feed efficiency in Bali cattle

Sintesis ZSM-5 dari Fly Ash Sawit dengan Variasi Waktu Sintesis dan Waktu Kalsinasi

Fly ash contains many elements of the high silica used as a source of silica for the synthesis of ZSM-5. ZSM-5 zeolite synthesis is one that is widely used in industry mainly as a catalyst. This is due to the ZSM-5 has a high activity and selectivity in several hydrocarbon conversion reactions. This study aimed to the synthesis of ZSM-5 of fly ash as a silica source without using templates with the time variation of the synthesis and calcination time. Synthesis performed in autoclaf at 190 ° C with a temperature variation of synthesis time 16, 18, 20 and 22 hours, calcination is done in a furnace to a temperature of 500 0 C with a variation of calcination time 4 hours, 5 hours and 6 hours. Synthesis products were analyzed by FTIR. The results showed that the best conditions for the synthesis of ZSM-5 from fly ash oil is at synthesis time of 20 hours and calcination time 4 hours. The content of ZSM-5 produced in the x-ray analysis is as much as 3%

Hubungan Relijiusitas dengan Self Awareness Mahasiswa Program Studi Bimbingan Penyuluhan Islam (Konseling) UAI

- Penelitian ini hendak melihat hubungan antara relijiusitas dengan self awareness pada mahasiswa/i prodi BPI (konseling) UAI. Dimana self awareness merupakan kecerdasan pemahaman diri sesuai dengan situasi dan kondisi, yang memiliki faktor penunjang bagi penguatan self awareness. Keberagamaan seseorang menjadi faktor penentu bagi bagaimana bersikap, kepeduliaannya dan lainnya. Dalam ajaran agama mengajarkan untuk berperilaku terpuji baik bagi diri maupun sesama. Data pada penelitian ini dengan kuisioner skala relijiusitas dan self awarenes yang telah mengalami uji validitas dan reabilitas. Penelitian dengan sample 84 mahasiswa/i prodi BPI yang merupakan jumlah populasi aktif ini memberikan hasil bahwa adanya hubungan yang signifikan antara relijiusitas dengan self awareness dengan derajat yang lemah. Penelitian ini sebagai awalan dari penelitian berikutnya yang lebih mendalam baik dari sisi variabel maupun sample dan alat analisis

Desain Mesin Penghancur (Shredder Machine) Batang Kelapa Sawit Berbasis Metode Design for Manufacture and Assembly (DFMA)

DFMA is defined as the design of a product or component which can facilitate the process of manufacturing and assembly process with other components to become a unified product. The utilization of palm oil is only limited to the fruit to produce oil, and to a certain extent the utilization of fiber fruit bunches and fronds to producefiber. Utilization in the form of particle board using oil palm trunk. From basic research on the utilization of oil palm trunk, then it needs tools to process oil palm trunk into raw material that will be processed to be particle board, paper materials and cattle food. There are several steps to design a shredder machinei.e DFMA methods for determining the shredder machine design with easy assembly and manufacture, calculations to determine the motor power is using, and the simulation of structural strength testing using Autodesk Inventor to get the value of the safety factor of the frame and the shaft. The results obtained efficiency values assembly design is 3.14% .Then, the calculation results of the machine element motor power required is 3 Hp at 1400 rpm rotation for oil palm trunk with a surface area of 1 cm x 10 cm. The analysis result of the frame structure and shaft used Autodesk Inventor to obtain the safety factor value of the frame is 6.41 and the shaft is 4.3

Analisis Faktor – Faktor Yang Mempengaruhi Produksi Industri Furniture Kaca Dan Alumunium Di Kota Pekanbaru

The purpose of this study is to examine the effects of factors the productivity of glass and alumunium furniture industry.The population used on this study is the entrepreneurship of glass and aluminum furniture industry in Pekanbaru. The sample was selected by all of population study, there is 15 glass and aluminum furniture industry. Collecting data was conducted by distributing 15 questionary to respondents.The data were analyzed using instrument testing comprising validity testingand reliability testing. Classical assumption testing consisted of normality testing,multicolinearity testing, and heterocdasticity testing.The analytical tool used in this study was Statistical Package for the Social Science (SPSS) version 16.0.The results of this study prove that capitalshas a significant effect on productivity with significant level of 0,000. Workers has a significant effect on productivity with significant level of 0,025. And materialshas a significant effect on productivity with significant level of 0,003. Overall, the capitals, workers, and materials did effect productivity by 93,9%. While 6,1% are influenced by other variables that did not examined on this research

Ketahanan Keluarga dan Kontribusinya Bagi Penanggulangan Faktor Terjadinya Perceraian

- Faktor ketidak harmonisan di dalam keluarga menjadi salah satu sebab terjadinya perceraian keluarga. Ketidak harmonisan keluarga ini disebabkan oleh adanya pergeseran nilai perkawinan. Pasangan suami istri kurang memahami esensi tujuan pernikahan dan berkeluarga yang menjadi salah satu nilai dalam ketahanan keluarga. Hal itu menyebabkan adanya ketidakcocokan, perselisihan, akhlak yang buruk, cemburu dan gangguan fihak luar serta adanya faktor ekonomi. Penelitian ini menggunakan metode kualitatif. Penelitian ini juga menggunakan data sekunder berupa data dari Pengadilan Agama Jakarta Selatan. Hasil kajian nya ialah (1). Diperlukan pemahaman kepada masyarakat tentang ketahanan keluarga agar setiap individu pasangan memahami konsep dan tujuan berumah tangga. (2). Optimalisasi lembaga BP4 dalam menjembatani penyelesaian konflik rumah tangga. (3). Penguatan sendi keluarga dari berbagai aspek baik ekonomi maupun sosial dan lainnya agar dapat meminimalisir tingkat perceraian. Kata Kunci – Ketahanan keluarga, faktor cerai, pernikaha

Viscous Cosmology and Thermodynamics of Apparent Horizon

It is shown that the differential form of Friedmann equations of FRW universe can be recast as a similar form of the first law, $T_{h}dS_{h} = dE + WdV$, of thermodynamics at the apparent horizon of FRW universe filled with the viscous fluid. It is also shown that the generalized second law of thermodynamics holds at the apparent horizon of FRW universe and preserves dominant energy condition.Comment: 8 page
