EVALUATION OF BIOLOGICAL VALUE OF COMPLETE FEED BASED ON CORN COB AND MIXED GRASS ON PRODUCTION PERFORMANCE OF ONGOLE. This study was aimed to obtain the feed formula, which is effective on the productivity of beef cattle (PO). This study consisted of two experimental stages, namely: 1). In vitro experiment, and 2). Biological (in vivo) experiment. t-test two sample assuming unequal variance was used as the statistical analysis on both experiments. The treatments of this research consisted of RA feed = 50% concentrate + 50% corn forage and RB feed = 50% concentrate + 50% mixed grass, and it was repeated 10 times. In vitro test was used to measure dry matter and organic matter digestibility and NH3 concentration (NH3). The biological experiment (in vivo) was used 20 PO cattles, 12-18 months of ages, with 120 - 180 kg of body weight to measure feed intake, nutrients digestibility DMD, OMD, Protein and energy digestibility, live weight gain (LWG) and feed conversion (FCR). The results showed DMD and OMD in vitro of RA were 67.88% dan 66.06%, respectively, lower than the DMD and OMD obtained in RB, i.e 71.15% dan 69.08%, respectively. Meanwhile, NH3 of RA was higher than RB, i.e: 3.20 vs 2.50 mM/L. The biological experiment showed the DMD, OMD, CPD, and DE (in vivo) of RA were 77.05%, 78.64%, 82.13%, and 83.48%, respectively, while the results obtained at RB were higher, i.e. 80.15%, 83.44%, 85.55%, and 87.46%, respectively. On the liveweight gain (LWG) of PO cattle, the RA ration produces 0.60 kg per head per day, lower than RB which produces 0.65 kg per head per day. The FCR of both ration was 0.11. It is concluded, complete feed based on forage corn and mixed grass can be used as standard feed for fattening of local beef cattle because it is able to give high nutrient digestibility and good feed conversion value Keywords: Complete feed, in vitro and in vivo digestibility, liveweight gain, feed conversio

UJI KARAKTERISTIK FISIK DAN KIMIA PAKAN LOKAL DAN IMPOR KUDA PACU MINAHASA

PHYSICAL AND CHEMICAL CHARACTERISTICS APPRAISAL OF LOCAL AND IMPORTED RACE HORSES FEED IN MINAHASA The present study was conducted to determine the physical characteristics and nutrient content of racehorse diets both local and imported feed used mostly by race horse breeders in Minahasa region. Race horse breeding management in Indonesia fully adopts methods used in developed countries. Race horse breeders in Minahasa have been practicing of using oats as an imported ingredient to replace local feed rice. This is due to the lack of further testing of local feed, so that race horse breeders practice and rely on using imported feed ingredients to feed their horses just before the horse racing.  A survey method was used to collect data, using interviews and direct observations on several race horses breeding farms. Types and amount of feed (forage and concentrates) both local and imported given to race horse were taken about 500gr for samples analysis. Data were statistically analyzed using t-test. The results showed that the nutrient content of imported feed ingredients significantly higher (P <0.05) compared with local feed. Physical characteristics (color, flavour, shape, and texture) of local food (rice) was significantly different (P <0.05) from that of imported feed (oats). It can be concluded that the nutrient content of imports feed is higher than that of local feed, and physical characteristics of oat and rice, different in colour, shape, aroma, and texture, on the other hand, oat and rice have the same physical shape.

Studi Parameter Pemesinan Proses EDM Terhadap Kekasaran Permukaan, Laju Pembuangan Geram Dan Keausan Elektroda Pada Baja Perkakas

Material removal rate, surface roughness, and electrode wear are correlated with machining parameters such as pulse on time, discharge current, and polarity. Usually, the selection of the process parameters was based on trial and error, which produced inconsistent machining performance and more setting time. The research aims to investigate the influence of machining parameters of EDM i.e., current, arc on time and polarity on the material removal rate and electrode (tool) wear. JS EDM NC60A was used in electro discharge machining of tool steel. Coppers (Cu) electrodes with dimension 24 mm x 24 mm x 8 mm. dielectric fluid was used ESSO Lector 35. Each machining test was performed at current setting of 6 A, 9 A, 12 A, 15A with variation of ton60 µs, 90 µS,120 µs and 150µ. The material removal rate of the workpiece and the wear of the electrode were obtained based on the calculation of the mass loss per machining time. Whereas the surface roughness were measured using surface roughness tester Surf Corder SE 1700 Fowler.It was found that the surface roughness, the material removal rate and the electrode wear rate were affected by machining parameters. The best result of material removal rate (MRR) at 15 A with ton 150 µs is 33 mm3/menit for positive polarity. The best surface roughness with value of Ra = 2.1 pm achieved at 6 A, ton90 &#956s for negative polarity

This research was carried out with the aim to determine the effect of providing different sources of fiber in feed on the apparent digestibility of crude fiber and hemicellulose in cobb strain of broilers. This study used 20 cobb strain of broilers 35-day-old. The design used was a Completely Randomized Design (CRD) with the treatment of 4 different fiber sources in the feed which was repeated 5 times. The treatments consisted of: R0 (commercial feed),R1 (commercial feed with coffe skin), R2 (commercial feed with rice bran), R3 (commercial feed with coconut pilp). Variables measured were: apparent digestibility of crude fiber and hemicellulose. Apparent-digestibility measurements using the total collection method. Data were analyzed using general linear model (MINITAB version 16), then differences between treatments were tested with Tukey’s simultaneous test. Apparent digestibility of crude fiber feed has a very different (P&lt;0,01) with treatment R2 and R1. The treatment of R2 was not significantly different (P&gt;0,05) from R1. Apparent digestibility test for hemicellulose shows that R3 is the same as  R0, but it is significantly different (P&lt;0,01) with treatment R2 and R1. The treatment od R2 was not significantly different (P&gt;0,05) from the treatment of R1. It was concluded that coconut pilp as a source of fiber in the feed of strain cobb of broilers provides better digestibility of coarse and hemicellulose fibers than coffe huks and coffe branKeywords: Apparent digestion of crude fiber, Apparent digestion of hemicellulose, strain cobb of broile

Rancang Bangun Pompa Air Tenaga Angin Untuk Pengairan Sawah Menggunakan Vertical Wind Turbine Tipe Savonius

Pompa air sangat efektif untuk  pengairan sawah terutama untuk daerah yang ketersediaan air tidak tercukupi sepanjang tahun, tetapi penggunakan pompa air juga mempunyai dampak ekonomi terhadap petani karena petani harus mengeluarkan biaya lebih untuk pembelian bahan bakar dan sewa pompa air tersebut. Sehingga diperlukan suatu alat yang dapat menjadi pompa air tanpa harus mengeluarkan biaya dalam penggunaannya. Di sisi lain, sawah sebagai salah satu lahan terbuka, memberikan perpindahan udara yang cukup untuk membantu terjadinya angin. Angin jika dimanfaatkan secara tepat bisa dijadikan sebagai energi  alternatif penggerak pompa air. Dari analisa lapangan didapatkan kondisi lahan pertanian terbuka di daerah itu mempunyai laju kecepatan angin yang termasuk kategori rendah, yaitu berkisar 2 – 3 m/detik. Dengan kondisi ini memerlukan perancangan turbin angin  yang mampu bekerja pada kondisi kecepatan angin yang rendah. Maka pemilihan turbin angin vertikal (VAWT) menjadi alternative terbaik. Tipe VAWT yang dipakai adalah tipe Savonius banyak tingkat untuk memungkinkan mendapatkan torsi yang tinggi. Pompa air tenaga angin dengan mekanisme pompa tali seal karet dapat digunakan untuk membantu sistem  pengairan  sawah.  Hasil pengujian skala laboratorium dengan bantuan blower sebagai sumber energi angin adalah pada putaran turbin 30.8 rpm dan putaran poros output 55 rpm debit yang dihasilkan 2,6 liter/menit. Pada putaran turbin 39 rpm dan putaran poros output 68 rpm debit yang dihasilkan 3,4 liter/menit. Sedangkan pada putaran turbin 39.5 rpm dan putaran poros output 71,7 rpm debit yang dihasilkan 4,2 liter/menit.Keywords : “Pompa Air Tenaga Angin”, “Vertical Axis Wind Turbine”, “Rotor Savonius”, “Pengairan Sawah
