Abstract

Telah dilakukan penelitian yang mengkaji tentang sintesis hidroksiapatit berbasis tulang sapi lokal Aceh. Kandungan kalsium (CaO) di dalam tulang sapi dapat dimanfaatkan untuk mensintesis hidroksiapatit. Pada penelitian ini, hidroksiapatit disintesis dari tulang sapi yang telah dicuci bersih dan dihilangkan dari lemak  dengan menggunakan NaOH. Tulang sapi dikeringkan dan dikalsinasi terlebih dahulu pada temperatur 1000oC selama 2 jam. Tulang sapi kering kemudian ditumbuk hingga dihasilkan serbuk. Untuk mendapatkan ukuran partikel yang seragam, serbuk tulang sapi dimilling dengan kecepatan putaran 250 rpm selama 5 jam sehingga dihasilkan serbuk tulang sapi murni yang berukuran nano. Kemudian serbuk dikarakterisasi menggunakan XRD (X-Ray Diffraction) untuk membuktikan terbentuknya fasa CaO. Serbuk CaO yang telah terbentuk disintesa menjadi hidroksiapatit menggunakan metode solid statereaction dengan cara menambah asam posfat. Selanjutnya, serbuk CaO dan asam posfat disintering pada temperatur 900oC selama 2 jam. Penentuan fasa hidroksiapatit ini dilakukan dengan melakukan pengujian XRD. Berdasarkan hasil pengujian XRD, fasa CaO dan hidroksiapatit telah berhasil terbentuk sempurna. The research that examines the synthesis hydroxyapatite of Aceh’s bovine bone has been done.

Abstract

It has been an explosion at the Fukushima Daiichi NPP caused by the fusion reaction between hydrogen and oxygen. Hydrogen is believed to be generated one of which comes from the oxidation reaction between the fuel cladding and water vapor in the reactor core due to the failure of coolant (LOCA=Loos of Coolant Accident). This study aims to estimate the amount of hydrogen gas that accumulates in the reactor core theoretically by using a model based on equilibrium mole of a chemical reaction. The zirconium cladding material is set as a limiting reagent that limits the formation of hydrogen in the reactor core. The estimation results show that the amount of hydrogen accumulated in the reactor is directly proportional to the mass of the oxidized zirconium with water vapor. The amount of hydrogen that accumulates for one fuel rod reaches 0.018 kg, for one assembly is 1.10 kg and for overall at Unit One reaches 441 kg, which these results have been enough to blow up the reactor.

Abstract

Sediment distribution in the river of Gampong Leungah was conducted to describe the sediment condition in the river bottom. Samples were taken at 10 stations which were divided into river stream and estuary area. Coring method was applied to collect sediment samples using modified 2.5 inch of PVC tube. Approximately of 10 cm of sediment thickness from surface were used for further processed using sieving analysis. We found that river stream area has a coarser sediment particle with better sorted sediment compared to estuary area. The input sediment materials from shore area resulting mixed sediment condition as generated to the poorer sortation condition in estuary. Distribusi sedimen sungai di Gampong Leungah dilakukan untuk menggambarkan pola sebaran sedimen yang terjadi di daerah tersebut. Pengambilan sampel sedimen dilakukan pada 10 stasiun yang terbagi pada daerah aliran sungai dan daerah muara Pengambilan sampel sedimen dilakukan dengan metode coring yang menggunakan pipa paralon berdiameter 2,5 inch dengan panjang 40 cm. Sampel yang digunakan dalam identifikasi adalah lapisan sedimen dengan ketebalan 10 cm dari permukaan. Karakteristik sedimen pada daerah aliran sungai lebih kasar dan sortasi yang lebih baik di bandingkan dengan sedimen yang berada di daerah muara. Adanya percampuran dengan sedimen pantai membuat daerah muara memiliki kondisi sortasi yang lebih buruk.

Abstract

ABSTRACTThe study of the utilization rate of the fishery port in Sawang Ba'u, Sawang subdistrict, Aceh Selatan District has been conducted, Aceh province. The research aims were to determine the level of utilization of the fishery facilities. The research scope was examining the utilization rate of basic facilities with three facilities namely the pier, swimming and land. The research was conducted in April 2018 using a direct survey method through primary data retrieval and secondary data. The Data obtained is analyzed by comparison of the classification available in PP Sawang Ba'u with regulation of Maritime Minister and Fisheries No. 8 year 2012 and the formula of General fisheries capture year 1984. In this research also made several frameworks of thought and various trees beginning analysis of each facility that is in the analysis includes Port dock data, the vast data of the port pool also land port that reference data sources originating from the port Fisheries and Marine Service and fisheries. The results showed that the utilization rate of landing docks and high-stirreed pools (105.25%) On the landing dock and on the swimming pool (≥ 100%), while the land utilization is still low (39.4%). Based on the results it needs to be done development of main facilities, especially the jetty and swimming pool because it exceeds the existing capacity to facilitate the activity of the movement of the ship in order not the occurrence of demolition delays. So that it can cause a decrease of the quality of fish until the fishermen lose on the catch, while on the port land is still needed optimization to be more optimal and done development gradually by formalizing the land. Owned by local residents must be claimed by the government and allocate new developments for local residents.Keywords: Sawang Ba’u fishing port, utilization rate, basic facilities, level of needs ABSTRAKTelah dilakukan penelitian tentang studi tingkat pemanfaatan fasilitas pokok Pelabuhan perikanan di Sawang Ba’u, Kecamatan Sawang, Kabupaten Aceh Selatan, Provinsi Aceh.

Abstract

The main obstacle which hinders the application of fuel cell fuels in motor vehicles today is the hydrogen storage tubes. One of the latest efforts in hydrogen storage research is to insert hydrogen in certain metals or called solid state hydrogen storage. Magnesium (Mg) is regarded as one of the material potential candidates absorbing hydrogen, because theoretically, it has the ability to absorb hydrogen in the large quantities of (7.6 wt%). This amount exceeds the minimum limit which is targeted Badan Energi Dunia (IEA), that is equal 5 wt%. However Mg has shortage, namely its kinetic reaction is very slow, it takes time to absorb hydrogen at least 60 minutes with very high operating temperatures (300-400 °C). The aim of this study is to improve the hydrogen desorption temperature hydrogen storage material based MgH2. In this method, milling of material is done in the time of 10 h with the variation of catalyst inserts a for 6wt%, 10wt% and 12 wt%. The results from XRD measurements in mind that the sample was reduced to scale nanocrystal. Phase that appears of the observation of result XRD is MgH2 phase as the main phase, and followed by Ni phase as minor phase. The result of observations with DSC, to the lowest temperature obtained on the sample with a weight of catalyst 12 wt% Ni catalyst that is equal to 376 °C. These results successfully repair pure temperature of Mg-based hydrides.
