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 study was conducted to identify the optimum Zn formula that could be added to dose 300 kg/ha NPK fertilizer with the additional 200 kg/ha urea, organic fertilizer 500 kg/ha and its implication on Zn nutrient uptake and paddy production.  Generally, paddy cultivation practices applied macro-synthetic fertilizers without returning crop residues and organic materials as a soil conditioner as well as to provide micronutrients. In addition, the accumulation of P in the soil is pressing the availability of Zn, at neutral pH to alkaline Zn is not available and relatively mobile, when the soil is waterlogged Zn would be settled, and usually Zn is never be fertilized. Moreover, the land is intensively used for the manufacture of bricks and tiles indicate experiencing Zn depletion will cause symptoms on leaves of rice plants reduced toughness, pale green after 2-4 days later on flooded would be krotik and dried up. The research of fertilization innovation on micronutrients were conducted on July 2014 – January 2015 in Green House Agriculture Faculty, the University of Gajah Mada where the planting media of this research was Inceptisol which taken from Kebumen. The treatment were 10 treatments with a dose of NPK Plus Zn 0.25% Zn content ranges from 0% to 2% Zn repeated 3 times using a complete randomized design (CRD). The results showed that the land was given an additional 1.75% Zn has provided the highest Zn content of 0.16 mg/kg with a content of Trubus tissues Zn 68,38 mg/kg. Whereas in the control treatment had the lowest score is 0.07 mg/kg with Zn content of trubus tissue was 47.85 mg/kg. Not seen an increase in yield due to the additional provision of 2% Zn to the dose of NPK fertilizer plus Zn were given, but the tendency dose of 1.75% Zn gives the highest production yield with and extrapolated enough to the total population reached 9.96 tons/ha while in control was only 3.45 tons/ha.

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

This research aims to examine the composition of the green belt and its ability to adsorb particles of lead (Pb), determine the amount of particulate emissions of lead in the ambient air resulting from vehicle traffic activities and evaluate the composition of green belt some streets. The research was conducted using a survey method, the technical implementation is done by observation, questionnaires and secondary data collection. Sampling was done by purposive sampling is the selection of the sample with certain considerations deemed relevant according to the research objectives. Data were analyzed descriptively. The result showed that the green belt in three streets was dominated by Angsana trees (Pterocarpus indicus) form a line 1 (one) row crops. The composition of the green belt type, quantity, function, size, and distribution of plants available have not been able to reduce the concentration of lead (Pb) and thus require rearrangement. The roads planted with tree of Angsana (Pterocarpus indicus) and Tanjung (Mimusops elengi) had concentrations of lead (Pb) lower, as much as 1,39 µg/m3 at Urip Sumoharjo and as much as 1,11 µg/m3 at Laksda Adisucipto compared the road that only planted tree of Angsana (Pterocarpus indicus) is contained at Ahmad Dahlan with (Pb) concentration as much as 1,56 µg/m3. Concentrations of lead (Pb) in the third road was approaching the threshold value, but still below the quality standards specified.

Abstract

One of the problems related to the establishment of mangosteen plantation is to obtain seedlings throughout the year, which can be solved by micropropagation.   The propagation of Mangosteen was done through somatic embryogenesis. The objective of this study was to determine the effect of Thidiazuron concentration in ½ MS medium to achieve somatic embryo stages of mangosteen seed. The study consisted of two experiments. Experiment 1: The embryogenic callus c.a.1 g derived from MS solid medium containing of Thidiazuron (0,1; 0,5; dan 1 mg/l) and 2,4-Dichlorophenoxy acetic acid (4,6,8 dan 10 mg/l) was subcultured into ½ MS0 liquid medium. 2). The embryogenic callus from the previous medium were subcultured into ½ MS liquid medium containing Thidiazuron (0, 1, 2, 4 dan 8 mg/L) and Casein hydrolysate 500 mg/L. The results showed that cell suspension were developed after mangosteen embryogenic callus subcultured into ½ MS0 liquid medium.  Somatic embryo stages such as globular, heart and torpedo were formed after the calli derived from the previous ½ MS solid medium containing 10 mg/L 2,4-D and 1 mg/L Thidiazuron were subcultured into ½ MS0 liquid medium in 8 weeks.  Cell suspension in ½ MS liquid medium with or without the addition of  Thidiazuron and Casein hydrolysate has induced the formation of embryo somatic stages such as globular, heart and torpedo after 6 months of incubation.

Abstract

Dange is a traditional food made from delicate wet sago starch and further roasted in forna. Dange has rectangle form, flat with approximately 0,5 cm thickness. In addition, dange is also well known for its light, tasteless, hardness and relatively not hygroscopy. To increase the quality of dange and improve its flavour, a research was performed to study the quality of dange substituted with mackerel fish meat. The treatment was arranged in two classifications factorial completely randomized design. The classifications were variation of mackerel fish meat (0%, 2%, 5% and 8%) and time of grill (1 minute, 2 minutes and 3 minutes). Furthermore, the dange product quality was tested chemical and sensory analysis. The chemical analysis consisted of moisture, protein, fat, ash and starch content. Whereas the different of dange product quality was tested sensory analysis using scoring test method and the consumers acceptance was tested by hedonic scale test method. It was found that the most liked dange was made from 5% substitute of mackerel fish meat at 1 minute grill. This dange had slightly brittle texture, yellow-white colour, fishy taste and relatively strong fishy flavour with 27.84% moisture, 3.98% protein, 0.50%fat, 2.48% ash and 57,78% starch content.
