Analysis of MSL TG-13 method by performing calibration of a 0.6% class-ranged 4,000 kPa pressure gauge had been conducted. The calibration was done by using a 0.1% class-ranged 40 bar test gauge as a standard. The purpose of the analysis was to verify the MSL TG-13 method with the widely used standard method Deutscher Kalibrierdienst (DKD-R 6-1). Parameters for the analysis were Error number (En) for the degree of equivalence of both methods, maximum error value according to the requirement in reference document BS en 837-1:1988 for each accuracy class. The result showed that MSL TG-13 method …

A simplified but effective automatic measurement system has been built to give an additional alternative to the more complicated older version apparatus for rainfall interception metering on a representative tree of a subcatchment area. The equipment was installed on Regional Clean Water Company (PDAM) Air Serkuk Sub-Basin, Kubu Watershed, Belitung in 2014. The indirect way, called water balance or weighing method, was used in this study, so that the developed gauge consisted of some gages for gross rainfall, throughfall, stemflow, and canopy area measurements respectively on the selected plan…
Pengukuran karakteristik akustik di dalam ruangan telah dilakukan untuk acara pembukaan dan penutupan pada kondisi sebelum dan setelah renovasi. Pengukuran sebelum renovasi memberi petunjuk bahwa kondisi akustik ruangan sangat buruk untuk menghasilkan kualitas akustik yang sesuai dengan peruntukannya. Oleh karena itu, ruangan tersebut direnovasi secara menyeluruh dan komprehensif. Hasil pengukuran parameter karakteristik akustik ruangan menunjukan bahwa pada kondisi ruangan sebelum renovasi menghasilkan nilai waktu dengung (reverberation time) rata-rata sangat besar, yaitu RT = 3,1 detik. Seme…
Rain gauges in Indonesia need recalibration at least twice a year, viz. at the end of dry season where the rain gauges will soon work harder and at the end of rainy season where usually there are many garbage on each rain gauge orifice. Based on the direct surveys in the fields and discussions at some rain gauge calibration laboratories in Indonesian western, central, and eastern parts, the calibration officers in the visited offices generally used manual rain gauge calibrators to recalibrate rain gauges on their fields. Therefore, the dependency of calibration results to the human beings is v…

The development of the word and the rise of acts such as the destruction of worship houses disputes between religious communities and the acts of terrorism can harm the social order that has been well tied by Bhinneka Tunggal Ika. Thus, understanding about “Bhinneka Tunggal Ika†is an important thing to be concerned and maintained by all elements of the nation. Because the diversity that has existed in Indonesia is a noble heritage deposited by the predecessors to be continued and maintained. Strengthening Bhinneka Tunggal Ika will be needed to reinforce the identity of Indonesia, …

Traditional medicine "Subur Kandungan" is a medicine that is widely used and produced in Madura. The problem to develop Madura’s herb is raw material that hasn’t the standardized medicine used for Madura’s traditional medicine, because that raw materials are mostly purchased from traditional markets. This led to the standardization of Madura’s traditional medicine is difficult to do. This condition causes didn’t known active compounds contained in the Madura’s medicine. This study was conducted to determine the content of phytochemical compounds from e…
Porang (Amarphophallus. oncophyllus) is a type of plant tubers that have the potential and prospects for development in Indonesia. In addition to readily available, plants are also capable of producing carbohydrates and high harvest index. The last few years a very large porang needs. Porang plant propagation is vegetative and generative in which to make the seeds are ready to harvest takes between 4-6 months. This study aims to determine kinds of the appropriate medium for growing plants porang network and determine the concentration of  each  medium,  so  we  get  a …
Indonesia has high biodiversity, especially plant species. There are many benefits that can be Obtained from various plants that grow in Indonesia, one of which is as a health supplement or medicinal raw material. Fast researches are important in the use of these plants so that bio-based products can be widely accepted. One of the important fast methods in analysing the benefits of plant chemical compounds is the in-silico prediction utilizing metadata spread over various pages providing scientific data about plants, their chemical compound content and biological activity. This study was focus…
Pemuliaan  tanaman  merupakan  suatu  kegiatan  yang  dilakukan  untuk memperbaiki karakter tanaman secara baka. Pemuliaan secara konvensional biasanya dilakukan melalui seleksi terhadap karakter-karakter yang menjadi target  atas dasar ciri- ciri fenotip/morfologi, namun penggunaan penanda morfologi ini kurang akurat dan tidak stabil karena karakter yang tampak bukan semata-mata menggambarkan informasi genetic tanaman tetapi sudah dipengaruhi oleh lingkungan. Seleksi yang akurat terhadap suatu karakter yang diinginkan dari tanaman  …
