Penelitian bertujuan mengkaji anasir lingkungan yang menentukan produksi kubis di lahan pasir pantai.Percobaan lapangan dilaksanakan di Samas, Bantul, Daerah Istimewa Yogyakarta pada musim hujan dan kemaraudari Januari-Agustus 2005. Musim hujan memiliki intensitas cahaya, suhu udara, dan suhu tanah lebih tinggi daripadamusim kemarau. Air pengatusan musim hujan lebih rendah daripada musim kemarau. Kadar prolin daun tidak berbedanyata antarmusim, yaitu 6,58 Î¼mol/g. Laju pertumbuhan tanaman minggu ke-8-10 ditentukan oleh intensitas cahaya(ISMH) dan air pengatusan sesuai persamaan Ylpt 8-10 = 211,73-0,151 X ismh -0,244 Xatus (R2=0,923**). Bobot segarhasil kubis ditentukan oleh suhu tanah dan air pengatusan mengikuti model Ybsh= 151,66 -2,96X stnh -0,0171 X atus(R2=0,612*). Tanaman kubis dapat tumbuh baik di lahan pasir pantai pada musim hujan maupun musim kemaraudengan hasil berkisar 37-40 t/ha.ABSTRACT. Saparso, Tohari, D. Shiddieq, and B. Setiadi. 2009. Environment Elements Determinant forCabbage Yield in Coastal Sandy Land. The objective of this study was to examine environmental determinant forcabbage yield in coastal sandy land. Field experiment was carried out in Samas, Bantul, Yogyakarta Special Provincein the rainy and dry season from January up to August 2005. The rainy season had higher radiation intensity, airtemperature, and soil temperature than the dry season. Drainage water, therefore, was smaller than those drainagewater at the dry season. Proline leaf content was not significantly different between season, of 6,58 Î¼mol/g. Plantgrowth rate was determined by radiation intensity and drainage according to equation Ylpt 8-10 = 211,73-0,151 Xismh -0,244 Xatus (R2=0,923**). The cabbage productiviy was determined by soil temperature and drainage as Ybsh =151,66 -2,96X stnh -0,0171 X atus (R2=0,612*). The cabbage crop grown well either in the rainy or dry season and itproduced 37,0-40,0 t/ha.

The experiment was conducted in Cilebut Experiment Station, Bogor, with the aim to improve the productivity of Kacang goats. Twenty male goats, 9-10 months old, with an average initial liveweight of 16.27 kg were used. The goats were randomly divided into four treatments with five animals each, and were kept by grouped pen system. The dietary treatments were: (R0) = Elephant grass (EG) + concentrate (C0), (R1) = EG + (95% C0 + 5% molasses), (R2) = EG + (90% C0 + 10% molasses), (R3) = EG + (85% C0 + 15% molasses), respectively. The Elephant grass was offered ad libitum while the concentrate was offered at 3% of total body weight per treatment group. The experiment was carried out for 14 weeks. Feed intake per treatment group, individual weight gain, and feed conversion were analyzed. Average daily gain was analyzed in a completely randomized design. The results indicated that R0 (0% molasses), R1 (5% molasses), R2 (10% molasses) and R3 (15% molasses), did not significantly affect the average daily weight gain (P>0.05) with an overall mean of ADG to be 55.6 g/head/day. Feed intake and feed conversion were not significantly different among dietary treatments with an average dry matter intake of 2,621 g/5 heads/day or 524 g/head/day; protein intake was 370 g/5 heads/day or 74.0 g/head/day with energy intake of 10.929 Mcal/5 heads/day or 2.186 Mcal/head/day, and feed conversion of 9.43. In conclusion, the fact that molasses addition to rations did not affect feed intake, daily weight gain and feed conversion indicating that the molasses addition did not improve the Kacang goats fattening productivity. Â Key words : Productivity, goats, molasses

An experiment was done to evaluate the protein-energy requirement for growing Kacang goats. Twelve males and 18 female goats, seven to eight months old were used in this study and randomized into three treatment groups, with four and six animals each, and were kept in individual pens. The treatments used were: R1= Elephant grass (E.G.) + concentrate C1 (21% CP; 3.9 Mcal GE/kg), R2 = E.G. + concentrate C2 (17% CP; 3.7 Mcal GE/kg), and R3 = E.G. + concentrate C3 (12% CP; 3.5 Mcal GE/kg), respectively. Fresh Elephant grass was offered in restricted, and concentrate was offered at 3% of body weight. The experiment was carried out for 12 weeks. Data were analysed by using factorial completely randomized design 2x3 (3 rations and 2 sexes). Parameters measured were: feed intake; average daily gain and feed conversion. The results indicated that among treatments there was no significant difference on dry matter (DM) and gross energy (GE) intake (P>0.05), but crude protein (CP) intake of R1 was 23,6% higher than treatment R2; treatment R2 was 38.1% higher than R3 (P<0.01). Average daily gain (ADG) between treatment R1 and R2, and between R2 and R3 were not significantly different (P>0.05), but treatment R1 was 36.9% and significantly higher than R3 (P<0.01). Feed conversion (FC) between R1 and R2, and between R2 and R3 were not significantly different (P>0.05), but ration R1 was more efficient than R3 (P<0.01). DM intake, GE intake, and ADG of male goats each were 19.4% (P<0.05); 19.0% (P<0.01), and 28.2% (P<0.01) significantly higher than the female goats. Feed conversion between male and female goats was not significantly different (P>0.05). It was concluded that protein intake and average daily gain were increased, and feed conversion was more efficient as the crude protein-energy levels increased in the ration. Feed intake and average daily gain of male goats were higher and feed conversion was more efficient than the female goats. Â Key words : Protein-energy, Kacang goat
