"The infrastructure of the transportation system plays an important and strategic part in the development of a country and serves to support economic progress by enabling the mobility of citizens and the distribution of goods from one region to another. However, communities have unequal access to the system and there are gaps in the regional infrastructure in Indonesia, leading to the requirement for a mapping of all 33 provincial capitals. In this study, we reviewed provisions for road, sea, air, and rail travel. The mapping result is expected to determine the pattern and the prioritization needed for future infrastructure development. A literature review was performed to establish assessment indicators for the mapping. The weighting of each indicator was based on a survey of stakeholders in transportation sectors, which was then analyzed using the Analytical Hierarchy Process. After weighting was completed, the infrastructure of each provincial capital was assessed to determine ratings from the highest to the lowest rank. Jakarta, Medan, Bandung, Surabaya, and Semarang obtained the highest rankings, while Manokwari, Serang, Mamuju, Ternate, and Palangkaraya were at the bottom. This result shows that provincial capitals in western Indonesia had better assessment results than those in the east. Therefore, improvements to the transportation infrastructure of the latter cities should be prioritized."

"The findings of numerousstudies on the responses of stream quality indicatorsto different levels of watershed development have been integrated into an impervious cover model. The focus on one development stressor, namely theimpervious cover, allows the decision makers to use the impervious cover model as a watershed planning toolto forecast stream response. In evaluating streamquality, the studies used various indicators such as pollutant loads, habitatquality, aquatic species diversity and abundance, and others. This studyaims to test the applicability of the imperviouscover model as a tool to set the threshold of catchment area developmentbased on the targeted water quality index. Themodel is represented by a linear relationship between the water quality indexas a response variable and catchment area imperviousness as an explanatoryvariable. The study area is an urbanized catchment area of a cascade-pondsystem located at the campus of Universitas Indonesia, Depok, West Java.Estimation of catchment area imperviousness is based on digital globe imageryand digitized based on identified rooftops. The water quality data to computethe water quality indices are collected from previous studies and relatedreports. The targeted water quality index is determinedbased on water use suitability referring to the Indonesian governmentregulation number 82/2001. Basedon the available data, an increasing tendency of temporal variation ofcatchment area imperviousness for each pond can be recognized, while waterquality index of each pond tends to decrease over time. In accordance with landcover distribution, spatial tendency indicates that imperviousness isdecreasing in downstream direction, while water quality index is increasing indownstream direction, in line with the characteristics of cascade ponds. Theresults demonstrate that despite the fact that the available data are verylimited, it is possible to use the linear relationship between catchment areaimperviousness and water quality index as a tool to set the threshold forfuture development on the catchment area of the cascade-pond system at thecampus of Universitas Indonesia with a minimum water quality index suitablejust for recreation activities."

"Cold formedsteel has relatively high width-to-thickness ratio elements, which causes it tobuckle easily. Combining it with timber laminas would be an effective solutionfor reducing this buckling problem. This research focuses on the connectionsystem of a cold formed steel-timber composite, which was obtainedby attaching several timber laminas to the web part of cold formedsteel using screws. The connection used two bolts that were 8 mm in diameter,as well as two different kinds of side plates: steel and plywood. Cold formedsteel 75Z08 and Swietenia mahagoni(moisture content 12.2%; specific gravity 0.77) were used for connections andwere loaded in parallel and perpendicular directions. In addition, theconnections of cold formed steel (without timber laminas) usingself-drilling screw fasteners were tested until failure. Numerical analysispredicting the load-slip curve and apparent yield load of the composite joints wascarried out using the DOWEL program and the European Yield Theory,respectively. The test results showed that the connection system with steelside plates is capable of accommodating the strength increase of compositemember, as it has a maximum load carrying capacity and initial slip modulus ofabout 4.5 and 2 times larger than those of the cold formed steel connections, respectively. In the caseof a connection system with plywood side plates, its joint properties aresimilar to those of the cold formed steel connection, except that it has largerjoint deformation."

"Perangkap sosial, ekonomi, budaya, dan teknologi yang memenjarakan bangsa ini terjadi akibat terobsesi pada dasar yang dianut tipologi lingkungan berbeda tentulah tidak akan menghasilkan solusi bagi tipologi lingkungan unik Indonesia. Solusi haruslah memnuhi syarat yang berwawasan lingkungan yaitu (1) secara lingkungan berlanjut (environmentally sustainable), (2) secara ekonomik menguntungkan (economically profitable), (3) secara teknologi, terkelola, dan (4) secara sosial dapat diterima. Di tengah masyarakat dunia masa depan, bangsa Indonesia harus memiliki ketahanan demi kelangsungan hidup. Visi bidang teknologi yang akan memegang peran utama bagi ketahanan dan keberlangsungan hidup bangsa adalah elektronika, sains materi, dan bioteknologi. Ketiga bidang utama ini benar-benar harus dipersiapkan agar bangsa ini tidak hanya menjadi konsumen dari produk ketiga teknologi tersebut., tetapi ikut berperan, setidaknya bagi kepentingan konsumen kita sendiri.

"The performance of a 20 MW gas turbine power plant was described by using the exergy analysis and data from the plant?s record books. The first and second laws of thermodynamics, as well as the mass and energy conservation law, were applied in each of the components. The results show that more exergy destruction occured in the combustion chamber up to 71.03% or 21.98 MW. Meanwhile, the lowest exergy occured in the compressor at 12.33% or 3.15 MW. Thermal efficiency of the gas turbine power plant, according to the first law, was 33.77%, and exergy efficiency was 32.25%."

"AbstrakPerbedaan pola penggunaan internet berhubungan erat dengan distribusi kekuasaan yang tidak setara dalam keluarga: antara suami dan istri, antara anak perempuan dan laki-laki. Teknologi internet yang mengalami domestifikasi ini berintegrasi dengan pembagian peran gender dalam keluarga dan merembes dalam praktik sosialisasi mengenai perilaku yang berkaitan dengan penggunaan komputer dan internet. Pola penggunaan komputer yang berbeda antara ayah dan ibu, melemahkan ketertarikan dan minat anak perempuan terhadap komputer dan internet (technophobia). Akan tetapi, dalam kajian Blogger Indonesia dengan menggunakan IES, dalam tulisan ini, menunjukkan bahwa perempuan dan laki-laki memiliki sikap yang sama terhadap internet apabila perempuan diberi akses dan waktu yang sama seperti laki-laki"

"East Java Province inIndonesia is the centre of the eastern Indonesia region and it has a fairlyhigh economic significance, which has contributed 14.85% to the national GrossDomestic Product (GDP). The role of Large and Medium Scale ManufacturingIndustry (LMSMI) clusters in this province is very important and strategic asone of the main drivers for economic progress and it becomes a part of theefforts to improve the society's life. Therefore, it is necessary to evaluatethe performance of LMSMI clusters continuously. The purpose of this study is toinvestigate the productivity changes of LMSMI clusters in East Java Province,Indonesia, so that they will be able to survive, grow and compete in facingglobal competition.

The result of this study indicates that 50% ofthe LMSMI clusters in East Java Province are in the category of improvedproductivity, while the remaining clusters are in the category of decliningproductivity."

"Forest destruction in Indonesia has become a very serious problem and global concern. Eco-labels aim to combat illegal logging, illegal trading, and forest conversion. Eco-labeling in the furniture industry is slower in Indonesia than in competing countries such as China and Vietnam, where China has reached more than 1000 Chain of Custody (CoC) certification industrial units and Vietnam 238 units, while Indonesia has achieved only 78 units. But eco-labeling is perceived as a pressure on the international trade of the furniture industry. This study examines how the furniture industry in Central Java and Yogyakarta understands eco-labeling and what efforts the industry is making. Eco-labeling has a positive impact on the industrial environment and sustainable forestry, and it increases credibility/corporate image, market share, and profit. But not all buyers demand eco-labeling, so some companies deal with eco-labeling either by applying for certification or by looking for buyers that do not require the eco-label. Buyers who do not require the eco-label result in companies having less motivation to seek CoC certification. Other views about eco-labeling in the industry are also counterproductive, producing further obstacles to eco-label certification. Eco-labeling is often understood as unfair competition from developed countries, implemented as a barrier to entry into trade, and as inconsistent with The General Agreement on Tariffs and Trade (GATT)/The World Trade Organization (WTO). Eco-labeling is often considered a new form of colonialism rather than an instrument of environmental management."
