Abstract

Kalimantan is one of the largest coal producing regions in Indonesia. With abundant mining products, mining companies in Kalimantan need transportation media that can cover most of the mining areas. Water transportation is the answer that mining company need to transport mining products such a coal product. The Mahakam River is the main water transportation medium used to connect areas that can not be traversed by land in Kalimantan. In order to get safe transportation a cruise line must be developed. The cruise line is made from bathymetry survey using Multibeam Echosounder. The purpose of this study is to provide a safe cruise line for ships to pass the Mahakam River. A path will be made from bathymetry data and built from two specification. First specification is indonesian standard from kramadibrata and second is from ship specification itself. The data used for this research is from PT. Seascape Surveys Indonesia. Because the bathymetry data is the property of PT.Seascape Surveys Indonesia, the coordinates of this research area can not be mentioned and local coordinates are used to maintain the confidentiality of the company's data. Bathymetric data were corrected with survey error parameters consisting  of  tidal correction  correction, sound velocity profiler, gradient, water level and patch test. The depth of bathymetry data has reference to EGM96 during data retrieval and LLWL with reference EGM08 for Map. From the analysis of bathymetry maps of the Mahakam River, there will be recommendation which ship can pass the mahakam river and which ship is can’t.

Abstract

Surabaya is the second largest city in Indonesia and has been categorized as a metropolitan. The development of Surabaya is quite fast in terms of physical development. That condition can be observed from the number of high rise buildings at the city centre corridors. One of the corridors in Surabaya city centre is Jalan Pang-lima Sudirman. The corridor is a high density mixed-used area, dominated by commercial and service such as office retails and hotels. From the measurement, it was found that land subsidence happened at Jalan Panglima Sudirman which in the future will impact on environmental physical condition at the location. Therefore, observation of certain items mainly related to urban physical element impact on land subsidence was important. The result expected is the visibility of urban physical element impact in land subsidence at the corridor of Jalan Panglima Sudirman Surabaya.

Abstract

Altimetry satellite technology is used to regulate sea level. Observations are carried out every year to study the dynamics of sea level in the world. Sea level anomalies (SLA) in each region have different values and vary greatly. The main cause that increases from sea level is the thermal increase that increases from the mass of water from melting ice and glaciers on the surface of the earth. Therefore, this research aims to calculate the SLA from the SARAL / AltiKa satellite data and Jason's satellite series to study the variability of sea level in Indonesia's western sea, namely: the Java Sea, Karimata Strait and the South China Sea. From the research conducted, sea level rise obtained using SARAL / AltiKa satellite data in the range of -10 mm to 8 mm at a rate of decline of 0,459 mm / year. Meanwhile, Jason's series satellite data produces sea surface variations of around -2 mm to 11 mm at a rate of decline of 0,817 mm / year. From these two satellite observations, sea level decreases occur in the Java Sea, while in the Karimata Strait and parts of the South China Sea increasing sea level rise. In addition, this study uses research analysis to study the association of SLA data from SARAL / AltiKa and Jason satellite observations. The results of comparative analysis are very strong and in line with the estimated coefficient value of 0,9332.Keywords: Altimetri, Jason, Perairan Indonesia, SARAL/AltiKa, Sea Level Anomaly, Trend

Abstract

Desa Ngepung, Kecamatan Lengkong, Kabupaten Nganjuk merupakan salah satu desa tertinggal di Propinsi Jawa Timur. Beberapa permasalahan yang ada seperti: kurangnya air bersih, sanitasi dan akses jalan yang sangat minim. Dibutuhkan perencanaan pembangunan agar desa dapat mandiri dan lepas dari ketertinggalan. Diperlukan data yang digunakan dalam perencanaan pembangunan, salah satunya informasi geospasial atau diseput peta. Dalam Program Pengabdian kepada Masyarakat ini, kegiatan bertujuan untuk membuat Peta Desa dengan menggunakan wahana Drone. Peta desa juga mengfasilitasi keinginan masyarakat dalam perencanaan pembangunan dengan cara melibatkan masyarakat dalam pembuatan peta tersebut (metode partisipatif).

Abstract

Gunung Semeru merupakan gunung api paling aktif di Indonesia dengan riwayat letusan sejak tahun 1800. Letusan gunung api dapat memengaruhi lapisan atmosfer akibat pelepasan abu dan gas dalam jumlah besar, yang berdampak pada lapisan troposfer. Penelitian ini bertujuan untuk mengamati variasi kandungan uap air atau precipitable water vapor (PWV) di lapisan troposfer akibat erupsi Gunung Semeru pada periode 2020–2023. Analisis dilakukan menggunakan data PWV dari beberapa stasiun Global Positioning System (GPS) kontinu di sekitar Gunung Semeru, dengan estimasi PWV berbasis pengolahan data GPS menggunakan perangkat lunak GIPSY-X 2.1. Hasil penelitian menunjukkan adanya hubungan positif antara peristiwa erupsi Gunung Semeru dan peningkatan kandungan uap air. Secara umum, pola variasi PWV selama erupsi menunjukkan peningkatan beberapa hari sebelum puncak erupsi, diikuti oleh penurunan bertahap pascaerupsi. Namun, dalam beberapa kejadian erupsi, pola yang berlawanan teramati, kemungkinan akibat pengaruh partikel SO₂ dan aerosol. Secara rata-rata, kandungan PWV meningkat sebesar 3,039% dalam tiga hari sebelum erupsi dan menurun sebesar 3,854% dalam tiga hari setelah erupsi pada periode 2020–2023.
