MANGROVE FOREST CONDITION IN PIRU BAY, WEST SERAM, MOLUCCAS
Get PDFInformation on condition and biodiversity of mangrove ecosystem to support a sustainable management of mangrove ecosystem is very important in the coastal region of Eti village, Piru Bay, West Seram, Molluccas. The purposes of this study were to determine the condition and biodiversity of mangrove ecosystem in the village of Eti, Gulf Piru. Filed data collection was conducted in November 2010 using the line transect method. The box size along the transects was made in accordance with its purposes such as 10 x 10 m2 for trees, 5 x 5 m2 for sapling, and 1 x 1 m2 for seed. The distance between the box transect was 25 m. Number of individuals of each species were counted and the diameter at the chest-height was also measured. Results showed that sixteen species were found within ten genera. There were 9 species of tree categories, 10 species of sapling categories, and 8 species of seed categories. The highest density and frequency of occurrence for the three categories was represented by Rhizophora apiculata, while the largest coverage percentage was represented by Sonneratia alba. The highest important value was also represented by Rhizophora apiculata. In general, the condition of mangrove forests in the village of Eti, Piru Bay was still relatively good, but the local community was very active to take advantage of these mangrove forests products such as charcoal, fencing, and wood that they sold every week. Therfore, it is necessary for local government efforts to protect the mangrove ecosystem from destructed activities of the local community.Keywords: mangrove forest, Rhizophora apiculata, Sonneratia alba, Teluk Piru, Molluuca
DISTRIBUTION AND PREDICTION ON HEAVY METALS POLLUTION LEVEL (Pb, Cd, Cu, Zn, and Ni) IN SEDIMENT IN BANGKA ISLAND WATERS USING LOAD POLLUTION INDEX AND GEOACCUMULATION INDEX
Get PDFBangka Island is rich in natural resources particularly tin minerals. The increasing of tin mining has elevated various wastes such as tailings, oil, and fuel coming from the sand scraper tin boat. These wastes containing toxic heavy metals may harmful to marine organism. Measurement of Pb, Cd, Cu, Zn, and Ni were carried out in September 2010. The purpose of this research was to predict the pollution degree of Pb, Cd, Cu, Zn, and Ni in sediment using two different methods namely geoaccumulation index (I_geo) and pollution load index (PLI). The samples of sediments were collected at 20 stations using Gravity Core. The content of heavy metals in all samples was determined using Atomic Absorption Spectrophotometer with a mixture of air and acetylene flame. The results showed that there was a different of prediction on sediment pollution level between Load Pollution Index with Geoaccumulation Index. According to Load Pollution Index, sediments in this waters were not polluted by Pb, Cd, Cu, Zn, and Ni (PLI<1). Based on Geoaccumulation Index, sediment were also not polluted by Pb, Cu, Zn, and Ni (Igeo<0). While for Cd, sediments divided into three categories, namely not polluted (Igeo<0), light polluted (0<Igeo<1), and medium pollued (1<Igeo<2). The concentration of the heavy metals still lower than that sediment quality guideline values. Keywords: Bangka Island, heavy metals, geoaccumulation index, pollution load index

Flexible superconducting ceramic polymer composites and method of making same, U.S. Patent 5,108,981
No full textSuperconducting ceramic material is woven into an interconnected structure and embedded in a polymer to produce a flexible, superconducting ceramic material. The polymer also provides protection from moisture. The ceramic polymer composite is fabricated by soaking a carbon fabric in a solution of metal nitrates, ethylene glycol and citric acid to yield a nominal composition of, for example, YBa2Cu3O7-x. Heat treatment results in the decomposition of the nitrates, organics and carbon fabric to produce an interconnected structure of the superconducting ceramic material which takes the shape of the original carbon fabric on a reduced scale. In addition, the processing conditions yield significant grain orientation. The superconducting grains of the ceramic material align along the direction of the original fabric weave which provides an improvement of the critical current densities
TAFSIR DAN PEMBAHARUAN PEMIKIRAN ISLAM DI INDONESIA ERA KEMERDEKAAN: (STUDI ANALISIS KITAB TAFSIR AL-FURQAN KARYA AHMAD HASSAN)
No full textThe conflict dynamics of revivalist and traditionalist Islamic groups always colorize development of ideological contest of religious live in Indonesia. One of the important episodes of this conflict dynamic occurred in the era of independence. Through this paper, the author is interested in portraying episodes of Islamic Revivalist dynamics in the independence era through the thoughts and works of influential revivalist scholars, namely Ahmad Hassan. This study aims to reveal the form of mediation of Ahmad Hassan's Islamic renewal in his book of tafsir Al-Furqan. The author uses a descriptive method of analysis with literature study techniques in reviewing the interpretation of Al-Furqan as the main object of research. The results showed that in mediating Ahmad Hassan's Islamic renewal, Kitab tafsir Al-Furqan accommodates and mediates Islamic renewal in two ways, namely formative and substantive ways. Formative way of mediation is indicated through the form of tafsir Al-Furqan as a literal and meaningful translation of tafsir. Critically, this form of translation aimed to make Al-Furqan accessible for Indonesian people at that time when they haven’t had proper understanding on Arabic literacy so that people could understand and refer to the meaning of the Qur'an directly. This is in line with Ahmad Hassan's renewal though about the Qur'an and hadith as the main sources of muslims. As for the substantive ways of mediation, tafsir Al-Furqan contains and expresses the thoughts of Ahmad Hassan's renewal as a substance in interpreting the verses of the Qur'an

Jakarta Bay receives various kinds of waste both from land and waters, including Polycyclic Aromatic Hydrocarbons organic compounds (PAH). These organic compounds are toxic to marine life. This study determines the content of PAH in sea water and sediments in relation to marine life and to find out the source of the PAH compounds in the Bay of Jakarta. Measurement of Polycyclic Aromatic Hydrocarbon levels were carried out in March 2011. Sea water samples were taken by using a water sampler and sediment samples taken using a grab at 15 sites. PAH content were analyzed using gas chromatography–Flame Ionization Detector. The results showed that the content of PAH in seawater in the western part of Jakarta Bay > middle > east. The content of PAH in the western of Jakarta Bay ranged from 201,57 to 474,68 ppb with PAH total 1404,68 ppb, in the middle area ranged from 104,61 to 337,07 ppb with PAH total 825,63 ppb, and in the eastern part ranged from 8.72 to 115,39 ppb with PAH total 806,73 ppb. This means that seawater in the western part receives the PAH compound more than the others. However, the content of PAH in sediments in the western part < middle < eastern. This means that sediment in the western part of Jakarta Bay accumulates PAH compound less than the others areas. The content of PAH in the western part of Jakarta Bay ranged from 1.92 to 64.241 ppm with PAH total 107,931 ppm, in middle part ranged from 16.14 to 77.71 ppb with PAH total 170,61 ppm, and in the eastern part range 8,72 to 115.39 ppm with PAH total 252,25 ppm. This means that sediment in the western area of Jakarta Bay accumulates the PAH compound less than the others. Sources of PAH in seawater and sediment came from several sources namely from combustion of organic material, combustion of petroleum, and from petroleum. PAH content in seawater has passed the Threshold Limit Value stated by KMNLH for marine life and also has passed the threshold value stated the Ministry of Environment and Handbook for Sediment Quality Assessment for marine organism.
