Abstract

Ikan nila (Nile tilapia) Oreochromis niloticus adalah spesies ikan air tawar asal Afrika yang saat ini telah dibudidayakan di lebih 100 negara di dunia. Tahun 2004 produksinya hanya mencapai 97.116 ton, tetapi pada tahun 2009 produksinya dapat mencapai 378.300 ton atau terjadi peningkatan sebesar 289%. Mudahnya ikan nila berkembang biak menyebabkan ikan ini menjadi prioritas untuk pengembangan usaha dan industri budidaya ikan dan dikenal dengan julukan aquatic chicken atau ikan yang dapat dikembangkan seperti industri ternak ayam. Tujuan dari perekayasaan dan pengembangan ikan nila SALINA adalah untuk menghasilkan benih hibrida ikan nila SALINA toleran salinitas tinggi untuk mendukung pengembangan usaha budidaya perikanan, peningkatan produksi dan pemanfaatan lahan tambak idle yang luasnya mencapai 60 % dari 1,4 juta lahan tambak idle yang terbengkalai tidak termanfaatkan akibat kerusakan lingkungan dari program intensifikasi budidaya udang pada periode tahun 1980 an. kata kunci : rekayasa produksi ikan nila salina, perairan payau, wilayah pesisir

Abstract

Indonesia’s disaster potential is very high and varied. Natural conditions, population and cultural diversity in Indonesia cause in increased risks due to natural disasters, man-made disasters and emergencies to be complex, on the other side Indonesia is rich in natural resources. Disaster relief should be directed from pre-disaster phase, during emergency response and post disaster. The initial phase of this effort is the need for understanding of all stakeholders (mainly institutions) about the development of the concept and paradigm change mitigation. By knowing the concept and development of this paradigm is expected that all stakeholders can do things from the smallest to the larger and synergies will occur from all stakeholders to minimize the impact of a disaster. From ancient times until now the concept of a paradigm in disaster management shift very rapidly starting from the conventional to the holistic paradigm. In general, the development paradigm is the conventional paradigm (relief & emergency), mitigation paradigm, development paradigm and paradigm of risk reduction. Paradigm that is now growing and effective enough to minimize the risk mitigation is the analogy of mitigation for diseases caused by poor environmental sanitation. The analogy with disease problems mentioned above, there are disasters which can now be viewed in the same perspective, where the current disaster is something that is not predictable and it is destiny or part of the risks of everyday life. The concentration of people and higher population levels worldwide would increase the risk of disasters and multiply the consequences of natural hazards as dangers that arise. However, based on science “of epidemiology disaster” actually most of these disasters can be prevented or at least many ways to reduce the impact of a disaster (mitigation actions). Like the war against disease, warfare should be fought against disaster by any person jointly and involve society as well as changes in social behavior as well as improvements in individual practices.Keywords : mitigation, disease, environmental sanitation, disaster

Abstract

Babon Watershed (DAS) is one of the watersheds which one located are Central Java. It has been used as a source of raw water for agriculture, industry, drinking water and other household needs. That needs to be assessed the level of sustainability in watershed management of the raw water. This study aims to analyze the sustainability index and the status of management of raw water from the three dimensions of sustainability. Analysis methods used “multidimensional scaling” (MDS) called Rap WARESMA. The results are expressed in index form and the status of sustainability. The analysis showed that the ecological dimension ofsustainability are at less status (26.54%), dimension less sustainable economicstatus (43.18%) and socio-cultural dimension to the status of sustainable enough(50.83%). Of the 30 attributes that were analyzed contained 15 attributes influencing sensitive to the index and the status of sustainability with a verysmall error at 95% confidence level.keywords: watershed, multidimensional scaling, water, sustainability watershed management

Abstract

The objectives of the research is to obtain upland data and information especially for extensifi cation of sugarcane development through optimal land fertilization. Furthermore, the impacts of this action are to increase the planting area of sugarcane and productivity. The research use Geographical Information System (GIS) in Brebes Regency, starting from June until October 2007 and the field survey was done at the end of August 2007. The results of the research showed that the suitable, conditionally suitable, and not suitable land for sugarcane cultivation in Brebes Regency reach to a high of 40,148 ha, 7,555 ha, and 124,071 ha respectively. The potential upland for sugarcane cultivation reach to a high of 38,264 ha. Based on the soil condition with low contents of N, P and K, the recommended dosage calculation of N, P, and K fertilizers for optimal sugarcane cultivation reach to a high of: N (ZA) = 575 kg/ha, P (SP-36) = 170 kg/ha, and K (KCl) = 600 kg/ha.Key words : sugarcane, upland for sugarcane

Abstract

The importance of exergy analysis in preliminary design of geothermal power has been proven. An exergy analysis was carried out and the locations and quantities of exergy losses, wastes and destructions in the different processes of the plan were pinpointed. The obtained results show that the total exergy available from production wells KMJ 68 was calculated to be 6967.55 kW. The total exergy received from wells which is connected during the analysis and enter into the separator was found to be 6337.91 kW in which 5808.8 kW is contained in the steam phase. The overall exergy efficiency for the power plant is 43.06% and the overall energy efficiency is 13.05 %, in both cases with respect to the exergy from the connected wells. The parts of the system with largest exergy destruction are the condenser, the turbine, and the disposed waste brinekeywords: exergy, irreversibility, geothermal power plant, KMJ 68
