Abstract

To reduced losses in rice farming requires the application of modern agricultural machinery in harvesting equipment, postharvest and processing. Varying knowledge of farmers and entrepreneur rice milling unit (RMU) in yield loss as well as the impacts of global climate change research should be conducted through a structured survey of farmers and entrepreneurs RMU in Yogyakarta. Results obtained demonstrate the preferred use of new type variety among farmers so that the tool is suitable harvest sickle cutting down system in districts of Bantul and Gunungkidul more popular as straw used for animal feed. More than 70% of farmers do at harvest time by looking at the panicle and leaf color. Utilization of power threshers more developed in Sleman because of such preferred cut up and threshing by stampede way. With the limitations of manpower, the farmer was forced to delay harvest in Gunungkidul. The thickness of the grain is dried in the sun need to be added so as not too thin and can produce more rice intact during milling. Entrepreneur RMU need to complete with seed cleaner to increase the yield, as well as using double-pass system so that quality and yield of rice produced would be better.

Abstract

The successful development of agriculture depends on the success in optimizing the utilization of natural resources owned. Potential sources of forage availability based on land resources is possible in each area there will be a difference, this difference is very important to be in the know as it will determine the further development model farm. From the results of the identification of problems in dryland farm development include (1) The availability of food in the dry season is very less; (2) Distance birth (calving interval) long; (3) low soil fertility and limited manpower. Fermented corn husk and rice straw fermentation can increase the protein content and improve digestibility. Provision of forage with corn planting pattern thinning meeting four times to get forage 22.5 tonnes / ha and corn dry as much as 4.2 tons / ha. Improvements pattern plants can guarantee the availability of forage throughout the year. Hermada grass planting in dry soil can produce forage 35.56 tonnes / ha or can accommodate 3.3 livestock units / year. Increased production of rice straw IP 300 and IP 400 can increase the production of rice straw up to 30%. Feed quality improvements at the farm level by fermenting corn husks with curing for 14 days plus 2% urea may contain crude protein ranged from 4.8% to 8.4%. Fermented rice straw by addition of 1 kg of probiotics and 2 kg of urea to 500 kg of dry rice straw can produce quality hay-scented and soft textured.

Abstract

The study was held inSimo village, Boyolali, Central Java.The study used field experiments with a single factor that arranged in randomized completely block design.The treatments were control (P0), Alang-alang as mulch (P1), Kirinyu as mulch (P2), and Kenikir as mulch (P3), each treatment was repeated three times.The parameters were plant height, number of leaf, fresh weight of plant, dry weight of plant, number of tuberper hill, weight of tuber per hill, yield, fresh weight and dry weight of weeds. The results showed that mulch grass, kirinyu and kenikir was not significantly affect plant height, leaf number, number of tubers per hill and yield per hectare.Mulching grass, and kenikir kirinyu affected on plant fresh weight, dry weight and plant weight of tubers per hill.Mulching kenikir improved the plant fresh weight, dry weight of plants and weight of tubers per hill.Morover, Alang-alang, Kirinyu, and Kenikir as organic mulch significanly decreased the growth and abundant of weed and improved the growth of shallot plant. Alang-alang was the most highest decreasing the growth of weed.

Abstract

A research to determine the effects of liquid organic fertilizer as a decomposer and nutrition source on the growth of rice plant (Oriza sativa L.). This research was conducted in Wirokerten, Botokenceng, Bantul, Yogyakarta. Field experiment was  arranged using Randomized Completely Block Design with 2 factors and three replications. The first factor was liquid organic fertilizer, consist of liquid organic fertilizer and witout liquid organic fertilizer. The second factor was the doses of SRI, consist of 25% SRI, 50% SRI, 75% SRI and 100% SRI (urea fertilizer 350 kg/ha, 150 kg/ha of SP-36 fertilizer and 150 kg/ha of KCl fertilizer). The result showed that the liquid organic fertilizer with dose 10 l/ha macro fertilizer and 5 l/ha micro fertilizer were not significantly increased the growth and yield of rice plant. Liquid organic fertilizer with dose 75% SRI was significantly increased the leaf number than dose of 25% and 100% SRI. Doses 25% and 100% of SRI with application the liquid organic fertilizer was significantly increased the weight of 1000 seeds. Doses of SRI was not significantly increased the rice yield per hectar.

Abstract

The development of urban area gives negative impact on the environmental aspects, such as the decreasing of areas for green open space. Therefore, it is necessary to implement the research about evaluation of green open space. This research aims to evaluate availability, form and create green open space structuring model in the district of Sleman. The research was conducted by survey method which technical implementation was done by observation, questionnaires, and primary and secondary data collection. The choice of location observations made purposively. The data that has been collected was analyzed descriptively. The results of this research showed that the district of Sleman have public green open space which is less that 35.84 hectares or 1.14% of the area that 624.4 hectares, was referred to UU RI No. 26 year 2007. A green open space structuring model as a reference model to increased the value of aesthetic, functional and to increast the existing green open spaces in the district of Sleman can be done with the developing of city parks, city forests, roadside plants and water fountains that have a functional and aesthetic value.

Abstract

This research was addressed to study the effect of plant growth media composition and nutrients concentration on yield of Cucumis melo L. The research was designed in complete factorial test of 4x4 with three replicates. Mixed growth media of bokashi:cocopeat:husk charcoal were tested in four compositions, i.e. 90%:5%:5% (M1), 80%:10%:10%(M2), 70%:15%:15% (M3) and 60%:20%:20% (M4) respectively. The other tested factor was nutrients concentraion that consists of four levels, i.e. control/no nutrient given (K0), 2 g/L (K1), 4 g/L (K2) and 6 g/L (K3). The Action 434 variety of Cucumis melo L. seedlings were then transplanted into 10 kg’s polybag and allowed to grow till harvested. The results showed that Chlorophyll content of M1 plants were higher than others, but the highest sugar content was resulted by M3 plants, and the highest thick of flesh fruit was resulted by interaction 60% bokashi:20% cocopeat:20% husk charcoal with 4 g/L nutrient concentration.

Abstract

A study examines the effect of moss removal and inorganic fertilizers on the growth of the tea (Camellia sinensis (L.) O.Kuntze) derived from seed after pruning. This research was conducted at the Research Center of Tea and Quinine in Gambung, Ciwidey.The research was managed using factorial experiment that arranged in Completely Randomized Design 4 x 4 with three replications. The first factor was the concentration of moss removal i.e. 0%, 1%, 2% and 3%. The second factor was the dose of inorganic fertilizer i.e. 100%, 80%, 60% and 40%. The result showed that there was no interaction between moss removal and inorganic fertilizer. In 2 % of moss removal showed the better result than 1% and 3% of moss removal in shoot numbers, shoot fresh weight, shoot dry weight. Inorganic fertilizer with 80% doses showed better result than doses 100%, 60% and 40% in shoot numbers, shoot fresh weight, shoot dry weight.
