"One of the most controversial issues of the water sector in recent years has been the impacts of large dams. Proponents have claimed that such structures are essential to meet the increasing water demands of the world and that their overall societal benefits far outweight the costs. In contrast, the opponents claim that social and environmental costs of large dams far exceed their benefits, and that the era of construction of large dams is over. A major reason as to why there is no consensus on the overall benefits of large dams is because objective, authoritative and comprehensive evaluations. "

"ABSTRAKPenelitian ini menguji pengaruh bendungan besar di Indonesia terhadap kesejahteraan rumah tangga. Penelitian ini bertujuan mengungkap potensi penurunan kesejahteraan khususnya pada rumah tangga yang tinggal relatif dekat lokasi bendungan. Hal ini penting sebagai upaya mitigasi masalah sosial ekonomi terhadap kebijakan pembangunan bendungan besar. Sampel rumah tangga didapatkan dari Survei Sosial Ekonomi Rumah Tangga (SUSENAS) tahun 2013-2018 serta Indonesia Family Life Survey (IFLS) gelombang 4 dan 5 pada 997 kecamatan terpilih. Hasil pengujian dengan menggunakan regresi ordinary least square dengan fixed effect menunjukkan korelasi negatif antara penambahan bendungan terhadap kesejahteraan rumah tangga yang tinggal relatif dekat lokasi bendungan dari sisi produksi, dan pengeluaran rumah tangga serta tidak signifikannya terhadap aktivitas kerja. Hasil ini mengindikasikan terjadinya potensi penurunan kesejahteraan khususnya pada rumah tangga yang tinggal dekat dengan bendungan besar.

ABSTRACTThis research aims to study effect of large dams development to the household-welfare in Indonesia. The purpose is to reveal potential welfare loss particularly to the household living in sub-district close to the dams placement. This is important to mitigate social and economic problem from dams policy perpective. Household sample data selected from National Social Economy Survey (SUSENAS) 2013-2018 and Indonesia Family Life Survey (IFLS) waves 4 and 5 in 997 sub-district sample. Using ordinary least square with fixed effect, this result show negative correlation both household-welfare and farm-productivity. In addition, the result have insignificance effect to work-activity. This result indicates potential welfare-disjunction to the household close to the large dams placement."

"this aim of this research is to develop an assessment method for hazardous substance value in automotive components for supporting green manufacturing. basically, the green manufacturing focuses od reducing environmental risks and impacts of industrial activities through elimination of resource waste, pollution and use of material containing hazardous substances. in this research, the method will be used to assess the the hazardous substance contained automotive components quantitatively. based on the values, the hazard level of components could be compared relatively. this research has retrieved hazardous substances were assessed based on the hazardous materials identification system (HMIS). furthermore, the more information would be processed using a weighting method to obtain a single value. this research has assessed several automotive components by using the method as care studies. the result of assessments are brake pad 6.6, brake pad with asbetos 7.6, brake shoes with asbetos 13.2, clutch disc 9.2, and clutch disc with asbetos 8.6."

"The onset of climate change has resulted in the development of strategies which try to mitigate the excessive generation of carbon dioxide (CO2). The trasnport sector for example, which contributes more than 10% of the global CO2 emmision, is promoting the use of biofuels in order to improve a nation's energy security and to reduce the sector's carbon footprint. Biofuels which are sourced from agricultural feedstocks will require more water resources than their fossil fuel counterparts and with climate change affecting rainfall patterns, it is expected that water resources will become more scarce. A fuzzy multi-objjective mathematical model for optimizing the biofuel supply chain in consideration of multiple regions is developed in this paper. The model seeks to identify how resources should be allocated in the presence of regional water constraints to satisfy the growing demand for biofuels. A case study on bioethanol produced from different indigenous feedstocks in three Asian countries is presented to demonstratee the capabilities of the model. "

"The Great East Japan Earthquake on March 11,2011 that left 20,000 people dead or missing have brought strong emosional impact of earthquake and tsunami throughout the whole world. Recently, Japanese government reported that an M9 Nankai Trough earthquake may result in as high as 323,000 deaths and devastate wide area of the coastline in Japan. In the March earthquake, the damages such as death, missing persons, and collapse became serious because of the disruption in information communication systems such as telephone network, local area network, cellular phone, etc. Therefore, disaster resistant information communication systems have become one of the major challenges for the researchers and engineers. in this paper, we discuss our proposed "Never Die Network" which is one of the disaster-resistant information communication systems and site examples based on our painful experiences of the Great East Japan Earhquake that had a great impact not only on ways of our lives but also on the future science and technology."
