Agricultural areas in Western Bandung Regency continue to face the threat due to land area reduction. Development of rural community-based agritourism is expected to benefit not only for rural communities but also urban communities to better understand, providing appreciation, as well as being a means of agriculture education. The factors that determine the development of agritourism, integrated farming systems, local institutional patterns, and the existing program would give a formulation of community-based agritourism development model that is oriented to added value and sustainability of agricultural systems. Assessment on sustainability of the communities in Cikahuripan and Cihideung villages in terms of social and spiritual aspects show good values towards sustainability while the ecological aspects requires corrective actions.

Development of sorghum processing industries is essential in expanding sorghum market as wells as it’s an economic value. Fertilizer is needed in planting. Nitrogen, phosphorus, and potassium availabilities are the most limiting factors for maximum growth and yield. Sorghum (Numbu Variety) was planted to evaluate the maximum and optimum rates of N, P, and K fertilizers. The research was conducted in Cikarawang field, Darmaga, Bogor from MarchJuly 2015 with multi-nutrient response method. Each experiment evaluated different rates of N, P, and K fertilizer with randomized complete block design and three replications. The fertilizer rates were 0, 50, 100, 150, and 200% of recommendation rate (100% N = 120 kg N ha-1, 100% P = 36 kg P2O5 ha-1, and 100% K = 90 kg K2O ha-1). The result showed relative yields of sorghum increased quadratically based on y = -0,0015x2 + 0,4011x + 67,571 for N, y = -0,0012x2 + 0,2917x + 78,457 for P2O5, and y = -0,001x2 + 0,2777x + 74,457 for K2O. The maximum rate for each nutrient was 160,4-43,7-124,9 kg N-P2O5-K2O ha-1. Fertilizer recommendation based on P threshold (no P) was 36,7-0,0-13,7 kg N-P2O5-K2O ha-1, K threshold (no K) was 22,0-0,0-0,0 kg N-P2O5-K2O ha-1, and no fertilizer needed on N threshold. The optimum rate fertilizer based on the yield vs. cost rule, therefore, the most economical recommendation would be 160,4-43,7-124,9 kg N-P2O5-K2O ha-1.

Cassava has been cultivated in almost the all region of Indonesia as a raw material of food, feed, and industries. The productivity of cassava was varied among the region due to the variation of varieties used and growth environment, especially rainfall or water availability. Water deficit or drought stress will decrease the growth and yield of cassava. Selecting tolerant variety to drought will be important to get high productivity. An experimental pot in the greenhouse has been conducted to know the growth and yield response to drought. Three varieties of cassava i.e Adira-1, Gajah, and Mangu were planted in the pot at three level of soil moisture content (SMC) 40-60, 60-80, and 80-100% of field capacity (FC). The cassava growth traits were influenced by SMC starting at 6 weeks after planting (WAP) for a number of leaves, at 8 WAP for stem girth, at 10 WAP for plant height, at 14 WAP for lobus width, and 15 WAP for lobus length. Root, stem, and leaves dry weight in the SMC of 40-60% FC were 64.4; 43.98, and 31.19% of the dry weight in 80-00% FC. Roots yield in the soil moisture content of 40-60% FC decreased by 76.2% and in the SMC of 40-60%, FC decreased by 38.4% compared to in the SMC of 80-100% FC. The water use efficiency and roots yield of Gajah variety were highest.

Studi Pengembangan Jagung Berkelanjutan melalui Integrasi dengan Sapi di Tuban, Jawa Timur Suwarto Suwarto; Iwan Prihantoro

Biji-bijian dan daging adalah dua komoditas penting di Indonesia. Jawa Timur adalah sentra produksi utama kedua komoditas tersebut sehingga perlu diusahakan keberlanjutannya. Permasalahan dalam produksi jagung adalah peningkatan harga input pupuk anorganik dan keterbatasan ketersediaan bahan tersebut. Permasalahan produksi ternak adalah keterbatasan pakan. Biomas batang, daun, kelobot, dan tongkol sebagai produk samping jagung dapat digunakan menjadi pakan ternak. Sebaliknya, kotoran sapi dapat digunakan sebagai sumber pupuk. Integrasi kedua sistem ini menjadi peluang untuk keberlanjutan produksi. Studi ini dilakukan untuk mengetahui keberlanjutan produksi jagung dan sapi di Tuban, Jawa Timur melalui penentuan skala dan tingkat keterpaduan integrasi. Survei terhadap 23 orang petani anggota Kelompok Tani Makaryo, Desa Waleran, Kecamatan Grabagan dilakukan untuk mengetahui pengusahaan jagung dan sapi. Untuk mengetahui efisiensi pemupukan, di lahan kelompok tani dilakukan penelitian dengan menggunakan empat dosis urea, yaitu 0, 100, 200, dan 300 kg/ha, dengan pupuk dasar 300 kg NPK Phonska dan 10 ton pupuk kandang. Skala integrasi yang dapat dilaksanakan oleh satu rumah tangga petani adalah 1 ha jagung dengan 2 ekor sapi dengan tingkat keterpaduan ekologis 1,1; ternak sapi memasok pupuk kandang untuk 1,1 ha kebun jagung. Penggunaan urea sebanyak 200 kg menghasilkan biji sebanyak 6.890 kg dan penerimaan tertinggi sebesar Rp21.288.000. Urea dihemat 100 kg ha-1 atau 9.651 ton untuk luas tanaman jagung 96.505 ha/tahun di Tuban. Secara ekonomis, integrasi peternakan sapi dengan kebun jagung dapat menghemat input luar sebanyak Rp230.000/ha atau Rp20.651 miliar/tahun. Pertanian jagung yang terintegrasi dengan sapi dapat mewujudkan pertanian berkelanjutan bermasukan luar rendah. Kata kunci: bermasukan luar rendah, biomas, integrasi, pakan, pupuk kandang

Sorghum is a potential crop as feed forage. The objective of the research was to obtain optimum dose of liming to improve the growth and productivity of sorghum (Sorghum bicolor (L.) Moench) biomass as feed forage. A completely randomized design with 4 treatments and 4 replications were applied for the research. The treatments were doses of dolomite lime addition i.e., 1) SD0 (dolomite lime addition at a dose of 0 ton/ha) as a control, 2) SD1 (dolomite lime addition at a dose of 1 ton/ha), 3) SD2 (dolomite lime addition at a dose of 2 ton/ha), and 4) SD3 (dolomite lime addition at a dose of 3 ton/ha). The result shows that supplementation of dolomite lime at doses of 2‒3 tons ha-1 can increase soil pH after a week of incubation. The dolomite lime addition at a dose of 3 tons ha-1 significantly increases (P<0.05) the plant height (2 weeks after planting) and the number of leaves from a week after planting until the end of the research (10 weeks after planting). In addition, this dose of dolomite addition (3 tons/ha) can increase fresh biomass productivity as well as dry biomass compared to control (SD0). In conclusion, supplementation of dolomite lime at a dose of 3 tons ha-1 was effective to increase the pH value of soil, plant height, leaves number, as well as fresh and dry biomass of sorghum plant. In addition, this dose of dolomite lime produces better green color of sorghum plant leaf compared to without liming. Keywords: biomass production, dolomite lime, feed forage, Sorghum bicolor (L.) Moench
