Abstract

The growth of the dairy industry in Indonesia is expected to be an attraction for the local farmers. The increasing number of breeders will have a negative impact on the increase of waste generated.Waste from the farm business can be a solid waste, gas and liquid waste. Animal husbandary waste can be processed to produce biogas as an energy alternative to oil burner and premium drive electricgenerators. From the measurement of CH4 content ranged from (56.67 - 62.8 %), while the CO2 content ranged between (36.36 - 42.64 %). This value is between methane and carbon dioxide content of the theoretical limit. Gasbio volume generated during the 24 hours ranged of 4.218 - 6.198M3, or the average of the gas produced as much: 5,096 M3 per day. Electricity generated = 3.822 kWh. Electricity power genset of 500 watt can burn for 7 hours. The results of laboratory analysis of sludge solids can be seen that the C / N ratio is still relatively high at 42.6, whereas the C / N ratio, which allowed ranged of 15-25. The C value is very high due to the organic composting process is too short, the element N is very low because the nitrogen is still in the complex chain that required the administration of N fastening bacteria such as : Azotobacter, Azotomonas, Pseudomonas.Keywords: cattle manure, biogas, energy listrk, compostAbstrakPertumbuhan industri susu olahan di Indonesia diharapkan akan mampu menjadi daya tarik bagi peternak lokal. Meningkatnya jumlah peternak akan berdampak negatif terhadap meningkatkanlimbah yang dihasilkan. Limbah dari usaha peternakan tersebut dapat berupa limbah padat, gas dan limbah cair. Limbah peternakana dapat diproses untuk menghasilkan biogas sebagai energi alternatif pengganti minyak kompor dan premium menggerakan generator listrik. Dari hasil pengukuran kandungan CH4 berkisar antara (56,67 – 62.8%), sedang kandungan CO2 berkisar antara (36.36 – 42,64%). Nilai tersebut berada diantara kandungan metan dan karbon dioksida pada batas secara teori. Volume gasbio yang dihasilkan selama 24 jam berkisar antara (4,218 - 6,198) M3,atau rata-rata gas yang dihasilkan sebanyak : 5,096 M3 perhari. Listrik yang dihasilkan = 3,822 kWh. Genset dengan daya 500 Watt maka listrik bisa menyala selama 7 jam. Dari hasil analisislaboratorium terhadap padatan sludge dapat diketahui bahwa C/N ratio tergolong masih tinggi yaitu 42,6, padahal C/N ratio yang diizinkan berkisar antara 15 – 25. Hal ini disebabkan karena Corganiknya sangat tinggi akibat proses komposing masih terlalu singkat, unsur N sangat rendah karena nitrogen masih dalam rantai yang kompleks sehingga diperlukan pemberian bakteripenambat N, diantaranya adalah: bakteri Azotobacter, Azotomonas, Pseudomonas.

Abstract

Maluku province is also famous as a producer of cajeput oil in Indonesia’s number one, but its potential until now have not been optimally utilized in accordance with the carrying capacity of land for public welfare. Melaleuca Cajeputi Roxb have not managed intensively as industrial plants, consequently low production. Based on the results of land suitability assessment, pewilayahan eucalyptus trees on the island of Buru include areas that are not so large, that is 188,743 ha or 20.60% of the total area of the island of Buru, with the details:Land is very suitable (S1) covering 54,832 hectares, or 6 percent of the total land area,mainly scattered in the northern part of Buru District, the floodplain physiography. Enough suitable land class (S2) on Buru Island reached a total area of 45,404 hectares of territory, with the main limiting factor is the rainfall and slope. Class marginal land suitable (S3) with severe limiting factor on regional conditions and slope roots reach a total area of 88,507 hectares.Class of land not available for this moment (N1) reached 513,937 hectares with a very heavy barrier so that if the current efforts will be made to harm the environment or very costly. Spread primarily on physiography tectonics with sloping hills more than 25 percent and its height more than 400 m above sea level. Land Not Available forever (N2) are lands that have very severe limiting factor, so for good both physically and economically impossible to be undertaken.Keywords: capability, suitability, land, cajuput oil

Abstract

In general, coastal areas have the physical and chemical properties of lessfertile land with an extreme dry climate, so that only a few plants that can live,including Jatropha curcas L. To enhance fertility and improve soil physicalproperties, need the addition of organic fertilizer. Source of compost canbe derived from a variety of wastes, including household waste and landfill.Quality compost landfill taken from Piyungan, Yogyakarta, has a high content of organic C, pH neutral, low N concentration, with the ratio C/N is very high. But compost landfill has an obstacle in the form of heavy metal containing high Cu and Pb. To prevent accumulation heavy metals into plant tissue or clean up heavy metals from the soil it was attempted by phytoremediation using jatropha plantation and bio-fertilizer that contains bacteria Azotobacter sp and Pseudomonas sp.From the research results can be informed that: (1) The city compost and biological fertilizers, can increase soil fertility with increasing nutrient content in soil. (2) Biofertilizers could inhibit the accumulation of copper (Cu) and lead (Pb) into Jatropha curcas L., (3)Jatropha plant can be classified as phytoremediation plants, because it can absorption heavy metals into leaf tissue.Key words: landfill compost , bio fertilizer, jatropha plants, heavy metals
