Abstrak: Fermented Jatropha curcas meal using Rhizopus oryzae could decrease the fat contained in the meal (5.8% Vs 0.39) and eliminated trypsin inhibitors up to 67.95 %. The decreasing of fat content indicated the eliminating of the main toxic substance contained in the meal, i.e. phorbolesters. Most of the phorbolesters could be extracted with the oil fraction of the Jatropha curcas meal. Hopefully, this treatment could convert the toxic jatropha curcas meal to high quality of meal as poultry feed. However, the fiber and phytate contained in the meal were still high. This experiment was conducted to study the effects of using fermented Jatropha curcas meal supplemented with cellulase and phytase in the kampong chicken diets on the growth and mortality rate. The experiment used 200 kampong chickens and were reared from day old chicks up to 10 weeks of age. This experiment using completely randomized design with 5 treatment diets and 4 replications, each replication used 10 birds. The experimental diets were: T0 (control diet, without Jatropha curcas meal), T1 (the diet contained 5% untreated Jatropha curcas meal), T2 (the diet contained 5% fermented Jatropha curcas meal + cellulase 200 ml/ton of feed), T3 (the diet contained 5% fermented Jatropha curcas meal + 1000 FTU phytase), and T4 (the diet contained 5% fermented Jatropha curcas meal + cellulase 200 ml/ton + 1000 FTU phytase). The parameters observed were feed consumption, body weight gain, final body weight, feed conversion ratio, and mortality rate. The data were analysed using analyses of variance. The results showed that there was no significant different on the parameters observed due to the treatments. However, feeding untreated Jatropha curcas meal in the diets (T1) decreased the body weight gain approximately 10.52% and final body weight approximately 10.13% compared to the control (T0). Feeding fermented Jatropha curcas meal supplemented with cellulase + phytase(T4) yielded the final body weight and feed conversion ratio similar to those of the control (T0) diet. The values of the final body weight of the T0, T1, T2, T3 and T4 were 955.08 g/bird, 858.33 g/bird, 872 g/bird, 935 g/bird, and 951.25 g/bird, respectively. The values of the feed conversion ratio of the T0, T1, T2, T3 and T4 were 2.93, 3.51, 3.49, 3.20, and 2.89, respectively. The values of the feed consumption per bird during 10 weeks of the T0, T1, T2, T3, and T4 were 2567.53 g, 2663.76 g, 2752.32 g, 2685.05g, and 2520.5 g, respectively. There was no mortality observed for all treatments.

Judul: Uji biologis bungkil biji jarak pagar (Jatropha curcas L.) dengan pengolahan ekstrak metanol dan fermentasi menggunakan Rhizopus oryzae serta Trichoderma viride pada ayam broiler
Abstrak: The utilization of Jatropha curcas meal as feedstuff is restricted by anti nutrients such as saponin, protease inhibitor, phytic acid and toxic substances like curcin and phorbolester contained in the Jatropha curcas meal. This experiment was aimed to evaluate the biological value of Jatropha curcas meal treated with methanol extraction and fermentation using Rhizopus oryzae and Trichoderma viride on broiler chickens. The biological test used twenty broiler chickens of four weeks of age and using after Sibbald method (1980). The treatments were P0 (Jatropha curcas meal without treatment), P1 (extracted Jatropha curcas meal using methanol), P2 (fermented Jatropha curcas meal using Rhizopus oryzae), and P3 (fermented Jatropha curcas meal using Trichoderma viride). Design of this study was completely randomized design, with four treatments and four replications. The data were analyzed using Analysis of Variance (ANOVA), and differences among treatments were further tested using Duncan Multiple Range test. The parameters observed were dry matter digestion, nitrogen retention, Apparent Metabolizable Energy (AME), calcium and phosporus absorption. The P1, P2 and P3 treatments highly significantly (P<0.01) reduced the dry matter digestion, AME and phosphorus absorption. The treatments significantly (P<0.05) reduced nitrogen retention, however its did not affect the calcium absorption. The values of dry matter digestion were 21.92% (P1), 8.88% (P2) and 21.88% (P3). The values of nitrogen retention were 36.39% (P1), 12.71% (P2) and 40.14% (P3). The values of apparent metabolizable energy were 1299.23 kcal/kg (P1), 1009.62 kcal/kg (P2) dan 1593.72 kcal/kg (P3). The values of calcium absorption were 41.04% (P1), 22,71% (P2) and 64.63% (P3). The values of absorptin phosphorus were -27.26% (P1), -95.4% (P2) and -3.94% (P3). These low values because of crude fiber contained in the treated Jatropha curcas meal. The conclusion of this experiment was Jatropha curcas meal as a single feedstuff of broiler chickens had low dry matter digestion, nitrogen retention, Apparent Metabolizable Energy, calcium and phosporus absorption. The usage of treated Jatropha curcas meal should be mixed.

Judul: Komposisi warna harmonis dalam suatu karya lansekap
Abstrak: Ilmu Arsitektur Pertamanan merupakan satu bidang disi- plin ilmu yang harus memenuhi kaedah secara fungsional berdaya guna dan secara estetis indah. Karya lansekap yang secara estetis indah dapat diwujudkan dengan adanya suatu perencanaan dan perancangan yang terkomposisi secara harmonis. Dalam suatu perancangan harus diperhatikan prinsip-prinsip perancangan, pengaturan elemen-elemen perancangan dan memahami aspek dan faktor disain yang ada. Elemen-elemen perancangan yang harus diperhatikan adalah bagaimana kesera- sian pengaturan warna, ukuran, bentuk, tekstur, garis serta elemen-elemen perancangan lainnya. Warna sebagai salah satu elemen disain mempunyai peranan yang sangat penting dalam mewujudkan suatu karya lansekap yang memuaskan. Pemilihan topik ini disebabkan oleh suatu fenomena yang menunjukkan bahwa pada umumnya warna merupakan daya tarik utama pada saat kita melewati suatu karya seni (3). Dengan demikian diharapkan penampilan suatu karya lansekap yang membosankan atau tidak teratur dapat dihindarkan dengan dikompilasikannya teori-teori komposisi warna-warna harmonis. Kemudian diadakan pengujian pada sekelompok populasi untuk melihat sampai sejauh mana pengetahuan terhadap komposisi warna yang harmonis. Warna pada hakekatnya adalah cahaya, dimana cahaya tersebut dapat terbias menghasilkan deretan warna merah, jingga, kuning, hijau, biru indigo, dan ungu. Sehingga sesungguhnya warna yang kita lihat sehari-hari merupakan hasil gelombang cahaya yang dipantulkan, dan penyerapan gelombang cahaya lainnya. Penampilan suatu warna sangat ditentukan. oleh tiga hal, yakni kondisi cahaya, pigmen pemantul dan keadaan alat mata dan emosi penglihat…dst
