Abstract

Pada 26 Desember 2004, gempa bumi dahsyat dan gelombang tsunami melanda Banda Aceh dan pesisir pantai Aceh lainnya. Selama masa rehabilitasi dan rekonstruksi akibat bencana alam ini, telah menghasilkan begitu banyak informasi dan dokumentasi yang sangat bernilai dilihat dari konteks sejarah, saintis, pendidikan dan mitigasi bencana. Berbagai informasi dan dokumentasi berupa rekaman kejadian, data serta kajian saintifik, data korban, lessons learned, model manajemen dan aktivitas rehab/rekons serta pelakunya, dan beragam informasi lain, akan hilang bila tidak dipreservasi dan dikelola dengan baik. Di sisi lain, informasi tersebut juga akan tak berarti bila tidak terdiseminasi untuk khalayak. Untuk itu, Pusat Riset Tsunami dan Mitigasi Bencana Universitas Syiah Kuala (TDMRC-Unsyiah) telah melakukan proses preservasi terhadap dokumentasi tersebut melalui program yang disebut Aceh Tsunami Digital Repository (ATDR). Aplikasi berbasis web DSpace telah dipertimbangkan untuk implementasi ATDR yang saat ini dapat diakses online dengan alamat http://atdr.tdmrc.org. BRR (Badan Rehabilitasi dan Rekonstruksi) NAD-Nias yang telah menuntaskan proses rehabilitasi dan rekonstruksi, meninggalkan pelajaran yang berharga dalam bentuk informasi dan dokumentasi digital. Saat ini informasi tersebut telah masuk menjadi salah satu segmen yang memperkaya koleksi dalam database ATDR. Lebih lanjut, ATDR akan mampu mendorong kolaborasi riset dan analisa data dari berbagai disisplin ilmu. Dengan menjaga keberlangsungan informasi, data akan terus tersedia untuk pengetahuan dimasa yang akan datang.

Abstract

The aim of this work is to determine the concentration of mercury in body lotion from several brands that are available in Banda Aceh. This research expected to provide information for the public and government related to the negative effects of harmful cosmetics that widely circulated. This information is useful into consideration of policy-making and monitoring the use of Hg metal. This study determined the type of body lotion cosmetics containing Hg metal by using Cold Vapor Atomic Absorption Spectroscopy (CVAAS) method. There are 22 samples and 11 of them have been selected by purposive sampling. The standard Hg calibration curve produces a linear line with the equation y = 0.0874x + 0.0729, and the correlation coefficient (R2) value of 0.9726. LOD value is 0.004854 ppb, and LOQ is 0.01681 ppb. The positive results were obtained from samples code TB3= 0.046, TB6= 0.01, and TB13= 0.004 ppb respectively. These results indicated the mercury level was still lower than 1 mg/L the threshold by drug and food control centers (BPOM).

Abstract

Effective and efficient information management can be achieved through the use of information technology. The emergence of the dengue virus is related to the uncontrolled breeding of the Aedes mosquito, also related to low levels of environmental hygiene. Control and prevention of the breeding of Aedes mosquitoes have been carried out in recent years, and still focused on eradication of the cases of Dengue Hemorrhagic Fever and Dengue Hemorrhagic Fever (DD & DDB). To prevent DD & DDB cases, the prevention action in decreasing number of DD & DDB is a major factor in controlling the spread of the disease and the breeding of Aedes mosquitoes. Accurate information is needed to provide a fast and accurate location notification of potential breeding areas for Aedes mosquitoes. This study aims to develop a framework for developing the Aedes (e-Aedes) mosquito warning system based on GIS (Geographic Information System), to identify a high-risk area for the Aedes mosquito breeding in residential area of Malaysia. Here, the expert interviews were conducted to confirm the initial framework of the study. This study chose qualitative and quantitative models as the research methodology. Thus, this study aimed to identify the awareness of community on DD &DDB issue. In order to achieve this study; we chose qualitative and quantitative models as the research methodology. This framework is verified through readiness, effectiveness and efficiency. The research results show a positive result, especially for effectiveness and efficiency which is can provide high reliability. This is shown from positive acceptance of respondents (the community) towards the framework of developing a GIS-based Aedes mosquito warning system (e-Aedes).

Abstract

Kajian ini mempresentasikan hubungan antara bebanan mekanis material Stainless Steel (SS) AISI 304 dengan kelakuan polarisasi. Lingkungan air laut buatan berupa 3.5% NaCl diasumsikan sebagai lingkungan korosif. Beban mekanis yang diaplikasikan adalah tegangan elastis pada spesimen C-Ring yang telah dipersiapkan. Hubungan antara nilai tegangan yang terjadi dan perilaku polarisasi direpresentasikan dalam kurva polarisasi dan laju korosi yang terjadi pada saat pengukuran. Korosi sumuran yang terjadi akibat adanya tegangan yang diberikan terhadap spesimen turut diperhatikan. Hasil penelitian menunjukkan bahwa laju korosi dipengaruhi oleh tingkat tegangan yang diterima oleh material SS AISI-304. Semakin tinggi tegangan yang diterima, maka semakin laju polarisasi yang terjadi pada kawasan yang di ekspos. Sehingga berimpak pada tingginya jumlah korosi sumuran pada area kajian. Didapati beban mekanis memberikan pengaruh yang konsisten terhadap kemunculan korosi tegang retak (SCC) dengan nilai laju korosi maksimum 4.662 mm/yr pada beban 868.380 N dibandingkan 3.975 mm/yr ketika spesimen tidak mendapat bebanan mekanis. Namun melalui kecenderungan grafik yaitu -0.0005 mm/yrN menunjukkan beban mekanis tidak secara signifikan dalam mempengaruhi laju korosi secara mutlak.

Abstract

This study aims to predict corrosion in water distribution pipes at the Bukit Indah Unimal campus. Corrosion is the damage to chemical elements in a metal that changes the original properties of the metal. There are four kinds of processes for corrosion, namely, one anode loses electrons, two cathodes accept electrons, three liquids and four metals connect the cathode and anode. The geoelectric resistivity method is used to determine the soil resistance properties of the subsurface layer. The wenner 4 pin method is a geoelectric data retrieval that is often used with the same pin spacing arrangement. Res2Dinv is software that is on a computer to generate 2-dimensional images from the resistivity data obtained and determine the layer below the surface. From the inverse results, the smallest error value can be obtained when iterating up to 4 times, namely Java Road 45.3%, Sulawesi Road 49.6%, Kalimantan Road 30.6%, Sumatra II Road 46.1%, Main Gate 41.1% Sumatra I 23.4%. Based on the data, the measurable results below the surface range from 0.05 m to 5 m.
