Abstract

The application of multibeam echosounder for seabed topography has been developing rapidly. Multibeam echosounder is a very efficient way to get a wide seabed topography coverage for each ping, so it can produce high-resolution seabed topography maps. These maps can be used as a reference for further investigation or exploration, for example geological studies, marine habitats and others. RV Baruna Jaya IV is operated by Laboratory for Marine Survey Technology – BPPT that have been hull mounted equipped a Germany technology multibeam echosunder Seabeam 1050D system. The Seabeam 1050D allow to sweep measuring the seabed topography using 126 beams simultaneously from port to starboard sites. R.V. Baruna Jaya IV and the Okeanos Explorer of NOAA have been conducted joint Indonesia - U.S. Expedition to Sangihe Talaud waters (INDEX SATAL) in the north area of the North Sulawesi Province during July - August, 2010. Seabed topography of less than 2000 metres were recorded by Seabeam 1050D system, the area of larger depths of 2000 metres to 6000 metres recorded by Simrad EM-302 from Okeanos Explorer. The seabed topography in Sangihe Talaud waters has a varied seabed topography. The new discovery that showed on the map is a 1600 m height of seamount, risen up from the depth of 2300m to 710m. Others geological seabed can be identified according to high resolution bathymetry map resulted from this study.Keywords: multibeam echosounder, seabed topography, seamount, Sangihe Talaud

Abstract

Sistem navigasi merupakan sistem yang memandu wahana gerak dari satu tempat ke tempat lainnya. Ada banyak sistem navigasi yang digunakan baik untuk kepentingan survei maupun untuk kepentingan umum. Sistem navigasi yang sudah dikenal luas adalah sistem navigasi berbasis satelit menggunakan global navigation satellite system (GNSS) atau global positioning system (GPS). GPS mempunyai kelemahan akibat faktor eksternal yakni sangat tergantung pada perambatan sinyal gelombang elektromagnetik dari satelit GPS ke receiver GPS. Sistem navigasi yang lainnya dan belum banyak dikenal namun sudah banyak digunakan adalah sistem navigasi inersial atau INS (inertial navigation system). INS ini merupakan sistem navigasi yang tidak terpengaruh oleh faktor eksternal, karena dibuat dengan mengikuti hukum gerak Newton, dan terdiri dari sensor accelerometer dan gyroscope. Biasanya INS ini dikombinasikan dengan sistem navigasi GPS untuk mendapatkan informasi navigasi yang lengkap dan akurat, yaitu posisi absolut, percepatan, kecepatan, arah, dan kelabilan (attitude) dengan frekuensi pengambilan data yang tinggi. Tulisan ini membahas tentang model dasar INS dari buku “Inertial Navigation Systems with Geodetic Applications” [Jekeli].Kata kunci:navigasi, accelerometer, gyroscope, inersial, GPS, Kalman filter

Abstract

Wilayah laut Indonesia bagian tengah dan timur merupakan perairan laut dalam dengan informasi batimetri yang masih terbatas. Data batimetri laut dalam dapat diperoleh menggunakan alat survei khusus, yaitu Multibeam Echosounder (MBES). MBES laut dalam pada Kapal Riset (KR) Baruna Jaya I mampu menghasilkan data batimetri hingga kedalaman 11 km. MBES laut dalam tersebut mempunyai dimensi fisik yang relatif besar, sehingga transducer MBES harus dipasang secara permanen pada tunas kapal. Sistem MBES laut dalam terdiri dari beberapa sensor yang terintegrasi dalam satu sistem akuisisi MBES. Agar menghasilkan data batimetri berkualitas tinggi, perlu dilakukan survei dimensional untuk memperoleh informasi sudut miss-alignment transducer MBES dan posisi secara 3D (tiga dimensi) sensor sistem MBES laut dalam secara akurat dalam satu referensi sistem koordinat. Paper ini bertujuan untuk memperoleh nilai ketidaklurusan (miss-alignment) transducer MBES dan nilai offset sensor - sensor yang terpasang pada KR Baruna Jaya I terhadap suatu sistem koordinat kapal menggunakan metode survei dimensional. Selain itu, hasil survei dimensional tersebut diverifikasi secara dinamis menggunakan metode kalibrasi patch test. Hasil survei dimensional menunjukkan pemasangan fairing sebagai rumah transducer MBES memenuhi toleransi dengan nilai roll: -0,089˚ dan yaw: 0,292˚ sedangkan nilai pitch (-0,120˚) tidak memenuhi toleransi. Hasil pemasangan transducer MBES menunjukkan nilai roll dan yaw memenuhi toleransi (roll: 0,012˚ dan yaw: 0,200˚), sedangkan nilai pitch di atas ambang toleransi (pitch: 0,698˚). Nilai kesalahan pemasangan transducer diverifikasi dengan hasil kalibrasi Patch Test MBES dan mendapatkan nilai roll: 0,20°, pitch: 0,45°, dan yaw: -1,43°.

Abstract

—  Design a web-based cotton Inventory System at PT. Argo manunggal TriastaPT. Argo Manunggal Triasta is an industrial company engaged in the field of Textile. This company is one of the many companies in Indonesia that has obstacles in the delivery of information, especially information data about reports in and out of goods, reports of final stock of goods and all problems related to inventory. This makes the data management process slow, as does the provision of information when needed so that it hinders the process ofselling / releasing goods. By designing a better system, it is expected to be able to assist and facilitate the ongoing system processes in managing data, including processing, compiling, and storing data which ultimately produces accurate data that can be used for company needs. The results of the analysis are described using the UML (Unified Modeling Language) modeling language. Implementation inthe form of the final results achieved is the formation of a web-based information system that can facilitate users in managing data.—  Design a web-based cotton Inventory System at PT.

Abstract

System failure in nuclear reactors can cause degradation of a reactor core, allowing melting and relocation of the corium to the lower plenum in the nuclear reactor system. In this study, a severe accident simulation was carried out using the Moving Particle Semi-Implicit (MPS) method. In this method, we model the relocation of molten corium on the reactor core (support plate) to the lower plenum for several conditions with variations: corium material, lower plenum conditions, temperature, viscosity, and density. Those treatments were carried out in order to be able to compare and analyze the characteristics of the corium melt by reviewing the velocity profiles. The formation of a corium pool and debris bed can result in significant temperature differences and high heat flux against the walls of the reactor vessel, causing a decrease in the integrity of the reactor vessel and reactor failure.Keywords: Corium, Uranium Dioxide (UO2), Zirconium Dioxide (ZrO2), Fluid Relocation, Moving Particle Semi-Implicit (MPS).

Abstract

The phenomenon of female converts marrying under the guardianship of religious leaders in Batu Ampar District presents a unique issue, as it does not entirely align with national legal procedures, yet enjoys broad acceptance within the local community. While earlier studies have focused on court-appointed guardians (wali hakim) or the role of wali muhakkam in emergencies, limited research has analyzed this phenomenon through the lens of hearing shari'ah. This study seeks to address that gap by exploring the underlying factors, examining the validity of the marriage process according to classical Islamic jurisprudence, and interpreting it through the objectives of Islamic law. Using a qualitative descriptive method, data were collected through interviews and field observations. The findings reveal that the factors prompting the use of religious leaders as marriage guardians include the absence of a Muslim lineage guardian, economic limitations in accessing formal legal procedures, social pressure to maintain family honour, and the high legitimacy of religious leaders within the community. From the perspective of fiqh procedures, the marriage fulfilled all the essential pillars and conditions, such as the presence of acceptance (offer and acceptance), two just witnesses, a guardian (still), and a dowry (mahar). From the viewpoint of maqashid syari’ah, the marriage achieved the protection of religion (hifzh al-din), life (hifzh al-nafs), honor (hifzh al-‘ird), lineage (hifzh al-nasl), and property (hifzh al-mal).
