2013 Characterization of External Morphology on Various Seeds in Purwodadi Botanic Garden. Dewi Ayu Lestari Seed is a form of mini plants (embryos), endosperm and other food reserves, with protection that consist skin seed and in the certain seeds contain additional structure. Basic knowledge about seed characterization is very important to be able deal with various problems in the field of seed technology. Seed characterization is needed on the process of species identification.Aim of this study is to know external morphology character of various seeds in Purwodadi Botanic Garden, which can be used for basic identification of certain seeds. Several parameters were observed in external morphology seeds characterization include size (length and width), diameter or… Lihat
2013 DEVELOPING A COMPUTER BASED AUDIOMETER FORHEARING LOSS SCREENING Ahmad Suandi & Denny Hermawanto AbstractAudiometric test is an ongoing task in almost all human activities. It presents a fundamental demand related to safety and health. Due to that, there is a need for sophisticated instrument to measure accurately the hearing loss within the human activities, especially for the people who work in noisy fields. The objective of this work is to develop the hearing loss screening system by invoving the computer software based audiometer. A friendly user interface has been conducted in order to evaluate the performance of audiometer software. From the practical result, it can be said that the designed computer based audiometer… Lihat

2013 Koleksi kultur in vitro ubi kayu (Manihot Esculenta Crantz) sebagai material perakitan bibit unggul N. Sri Hartati, N. Rahman, H. Fitriani, E. Sudarmonowati Penyediaan bibit ubi kayu unggul sangat diperlukan untuk memenuhi produksi ubi kayu nasional sebagai bahan pangan maupun bahan baku industri. Teknik kultur in vitro dapat diaplikasikan untuk propagasi bibit ubi kayu unggul maupun untuk penyediaan material tanaman guna pemuliaan lebih lanjut. Pada penelitian ini telah dilakukan pengembangan koleksi kultur in vitro 10 genotip ubi kayu unggul (Apuy, Iding, Kristal Merah, Mentega 1, Mentega 2, Manggu, Roti, dan Ubi Kuning) dan varitas unggul nasional (Adira 1 dan Adira 4). Optimasi metoda sterilisasi meliputi jenis dan variasi waktu perendaman dalam sterilan serta sumber eksplan (asal koleksi lapang dan rumah kaca) juga dilakukan… Lihat

2013 Electricity Generation from Tapioca Wastewater Using Dual Chamber Microbial Fuel Cell (DCMFC) with Saccharomyces cerevisiae as Biocatalysts Source Dani Permana, Herlian Eriska Putra, Djaenudin, Diana Rahayuningwulan, and Hari Rom Hariyadi Microbial fuel cell (MFC) is one of alternative renewable fuel cell technologies. MFC utilizes oxidation processes of chemical compounds by biocatalyst to produce low power electricity energy. Although the generation of the electricity is still in mW scale, MFC has a great potential and promising technology for the future application. MFC is not only used for electricity generation, but also for removal of the organic matter in wastewater so it can decrease the Chemical Oxygen Demand (COD) parameter of wastewater. The aims of this study are to decrease the concentration of organic matter and to generate electricity from tapioca wastewater… Lihat
2013 Pressing Problems: Distribution, Threats, and Conservation Status of the Monitor Lizards (Varanidae: Varanus spp.) of Southeast Asia and the Indo-Australian Archipelago Koch, Andr, T. Ziegler, W. Bhme, E. Arida, and M. Auliya We update an earlier review (Mertens 1959) of the monitor lizards of Southeast Asia and the Indo- Australian Archipelago, emphasizing the importance of this island region as a center of varanid diversity and endemism. Currently, 44 monitor lizard species (i.e., 60 persen of the known global varanid diversity) are recognized from this vast study region. New Guinea and the surrounding offshore islands harbor the highest diversity in terms of species (15) and subgenera (four). We provide a detailed identification key to all monitor lizards found in the study area. Moreover, we critically review the conservation status of all monitor lizard… Lihat
2013 Development of a New phase Change Biogas for Renewable Energy storage system Muhammad Kismurtono, Satriyo Krido Wahono , Roni Maryana dan Wahyu Anggo Rizal The presence of CO2 in biogas does not give to contribute to the calorific or heating value and are often washed out in purification plant in order to obtain a gas with almost 100 persen (volume/volume) and dangerous effect on environment. Therefore, CO2 must be eliminated from the biogas and the corresponding phenomena of mass transfer with chemical reaction of packed column have to be studied. The purpose of this research is to analyze theoretically mass transfer phenomena of CO2 chemical absorption in biogas using aqueous NaOH. 1.5 M in packed column and to support procurement of energy alternative in… Lihat
