Abstract

Waste water utilization in palm oil mills (POMs) in Indonesia is limited only for land application and in some palm oil mills the waste water is unutilized and it is only discharged to a river. The technology of methane gas utilization produced from waste water have been developed, unfortunately economical barrier is a big problem to implement it in the POMs. Since Clean Development Mechanism (CDM) have been being introducing in Indonesia, many foreign investors who looking for Certified Emission Reduction (CER) visit and investigate potential reductions in Indonesia. Using CDM Mechanism, it will change feasibility of an activity of methane gas capture. An income from selling CER makes theeconomical feasibility of methane gas capture increase. The purpose of this study is to investigate the potential methane gas produced in waste water pond in all POM owned by PTPN V, located in Riau Province. Area of own plantation, amount of processed (Fresh Fruit Bunch (FFB) and distance of the location are proposed as a consideration for selecting candidate locations. The potentialmethane gas captured was calculated. It was known that four POMs have a potential methane gas amount produced from waste water pond, and the investment in those locations were feasible based on the NPV calculation result. Utilization of captured methane gas as a fuel for power generation is inconsiderate, because negotiation is predicted will be takes a long time.Key words: green house gasses, palm oil mill, empty fruit bunch, fresh fruit bunch, palm mill oil effluent, clean development mechanism

Abstract

Sampah yang tidak dipilah dengan baik disumber akan memiliki komposisi sampah beragam dan tinggi kadar air. Kondisi ini menimbulkan permasalahan kesehatan baik bagi masyarakat yang tinggal dekat dengan pembuangan akhir maupun yang tidak. Sampah dengan criteria seperti ini, dapat diolah dengan teknologi hidrotermal. Teknologi hidrotermal memanfaatkan sifat air yang unik dan hanya berlangsung pada suhu dan tekanan yang tinggi. Hasil pengolahan sampah campuran dengan teknologi hidrotermal, menghasilkan produk yaitu bahan bakar padat. Bahan bakar padat ini memiliki nilai kalor yang setara dengan batubara batubara sub-bituminus grade rendah. Tantangan pengembangan teknologi hidrotermal untuk mengolah sampah datang dari segi pembiayaan, proses pengeringan produk, dan modeling pembakaran bahan bakar produk.  kata kunci : sampah, campuran, kadar air tinggi, hidrotermal, bahan bakar padat

Abstract

The northern part of java coastline in particular in Dadap Valley and Limbangannearby to Indramayu was heavily destroyed by erosion affected by strong wavecoming from opensea.It showed that some areas such as in Pamanukan coastline seemed to be heavily threated by erosion. This study was carried out by scientist of BPPT with the Objective of understanding the characteristic of sediments affected by erosion in Indramayu coast areas. According to information from local people living nearby coast and beach of Indramayu, The erosion destroyed coastline approximately 10-20 meter every year. Based on grain size analysis the sediments reveald 3 catagories of environment covered a long coast areas in Indramayu as follow :1. Coast sediments ; consisting of fein coastal sand, Silt.2. Delta sediments ; Siltig sand with Mollusca fragments.3. Flood upland sediments; Humous clay, silt, middle to coarse sands.The Occurrence of fein sand sediment deposition on the upper layer of coastalareas indicated that areas may influenced directly also with strong long shorecurrent.Keywords: sediment characteristic, coast, delta sediments, flood upland sediments, Delta , sediment abrasion

Abstract

Industrial parks play a signifi cant role in the production and use of goods and services. The proper management of solid waste is a major challenge for industrial parks due to the large quantity of wastes and the variability of waste characteristics from these types of developments. Therefore, integrated solid waste management has become very crucial to the industrial park managers. Such an approach requires industrial park managers to assess the overall use of resources, and to seek waste reduction, reuse and recycling opportunities both at the individual company level and among different tenant companies. The adoption of this method can bring both economic and environmental benefits.Key words : SWM, Industrial Park, 3R

Abstract

Generally, wastewater of nata de coco industry contains suspended solids and COD were high, ranging from 90,000 mg / l. The high level of of the wastewater pollutants, resulting in nata de coco industry can not be directly disposed of its wastewater into the environment agency. Appropriate technology required in order to process the waste water so that the treated water can meet the environmental quality standards that are allowed. Designing the waste water treatment plant that is suitable and efficient for treating industrial wastewater nata de coco is the activated sludge process. Wastewater treatment using activated sludge process of conventional (standard) generally consists of initial sedimentation, aeration and final sedimentation.Keywords : Activated Sludge, Design, IPAL

Abstract

An evaluation of the water quality at the hatchery of Tanjung Riau was conducted to understand the water quality status at the several place of the hatchery unit such as brood stock tanks, larva rearing tank, water storage tank, fi ngerling tank as well as the source of the water supply. The water quality status of Tanjung Riau generally is in a good condition to support the hatchery activities, but for turbidity and salinity were in the exceed and below the normal status and its infl uence on the spawning activity. To overcome the problem on the spawning of the brood stock, the improving of water supply with higher salinity and low turbidity should be set up to ensure the succeeded of the spawning.Key words : Water quality, grouper brood stock, hatchery,Tanjung Riau Batam

Abstract

Land is limited and non-renewable resource, on the other hand, people who need the land for development grow quickly. This paper discuss about the evaluation of land resource for plantation estate development planning in Banyuwangi District. General information regarding to physical environment are presented in order to know an overview of the study area. The Methodology of land suitability classifi cation corresponding to the selected plantation crops are briefl y explained, then, the results of the study are discussed. The study area consist of 9 physiographic spread from the fl at slope near the cost and verysteep slope near the mountain. Based on the land physical evaluation shows that the parent materials of the land are dominated by volcanic and lime stone. The results of the suitability classifi cation indicate that coconut crop could grow well in most of the plain up to undulating area. The land which suitable for coffee, clove and Vanilla cultivation are very small compared to the total of the study area and they are mostly located in the middle of the study area. Limiting factors of land suitability are mainly very diffi cult to upgrade, such us steep slope, soil effective depth, soil porosity, and drainage. In general, Banyuwangi District has a high potency of land for plantation estate extension.Keywords: land suitability, plantation estate, GIS, agriculture

Abstract

Abstrak Pembangunan rel kereta api memberi dampak positif dalam peningkatan transportasi tetapi disisi lain ada dampak negatif pada waktu proses pembangunannya yaitu pada waktu pembersihan lahan. Dampak ini berupapencemaran udara yang diakibatkan adanya kegiatan pembersihan lahandan transportasi material untuk melaksanakan pembersihan lahan maupunhasil dari kegiatan ini. Gangguan kesehatan misalnya ISPA (Infeksi SaluranPernafasan Atas), kanker pada paru-paru atau organ tubuh lainnya, penyakitpada saluran tenggorokan yang bersifat akut maupun kronis. Survei kuesioner dan wawancara tentang kesehatan masyarakat dan kesehatan lingkungan yang terdiri atas pola penyakit, tempat berobat responden, sumber air bersih, kepemilikan MCK (Mandi Cuci Kakus) dan kebiasaan membuang sampah telah dilakukan terhadap 420 responden masyarakat yang bertempat tinggal disepanjang jalur rel koridor Jakarta-Surabaya. Berdasarkan hasil survai tersebut dan konsentrasi pencemar di udara maka telah dihitung penambahan jumlah penderita ISPA akibat pencemaran udara dari kegiatan pembersihan lahan dalam pembangunan rel kereta api.Kata kunci : pencemaran udara, ISPA (infeksi saluran pernafasan atas),MCK (mandi cuci kakus)
