Abstract

This research is undermined by the dynamics of the current patterns of the Mahakam River, which is a crucial element in understanding the waters including the safety of the river transportation. The method used in this study is to take field data horizontally using the Current Meter tool, which is then continued with the analysis process with the help of ArcGIS software. The results of the research show that the speed patterns and direction of the flow of the river have different significance in each depth, as for the direction pattern of the current of the Mahakam River dominates from top to bottom, the cause of the occurrence of different direction of flow due to the topographic factors of the base river.

Abstract

The purpose of this research is to explain the method of calculating coal volume using Gemcom Surpac 6.3 software. This research also aims to present the amount of coal tonnage in comparison to volume calculations for the period of November 2022. Calculating coal volume is crucial in determining the quantity of mineral deposits. This volume calculation is done as accurately and precisely as possible to produce accurate volume and tonnage. The method used in this research is net volume calculation (grid/borrow pit), where the excavation volume is the difference between cut and fill during a specific period. The data used in this research is secondary data. The results of this research are in the form of coal volume calculation and coal tonnage for one month of excavation in November 2022 using Gemcom Surpac software with the net volume method. From the calculation results, the coal volume is 139,309.26 tons, with each seam M being 66,116.02 tons, seam Q1 being 33,563.89 tons, and seam Q3 being 39,629.35 tons. For the density of newly excavated coal seams, it is 1.00, so it can be said that whatever the calculated coal volume using Gemcom Surpac software is the result of the tonnage itself. The result of coal volume calculation also has a standard deviation value of 1.96%. The calculation result does not exceed the standard deviation set by PT Ansaf Inti Resources, which is ≤ 3%

Abstract

Survei Batimetri adalah kegiatan survei lapangan untuk mendapatkan kondisi topografi dasar perairan, data kedalaman, data pasang surut, maupun lokasi obyek yang membahayakan pelayaran. Survei batimetri pada penelitian ini berlokasi di Sungai Mahakam untuk mengetahui kondisi topografi dasar perairan dan data hidrografi lainnya. Kecelakaan sering terjadi di jalur lalu lintas sungai Mahakam (di bawah jembatan Mahakam Kembar). Selama tahun 2019 sampai 2021, kapal tongkang menabrak jembatan Mahakam Samarinda sebanyak 4 kali di pilar sisi jembatan Mahakam yang lama. Permasalahan tersebut melatarbelakangi penelitian ini untuk mengetahui kedalaman dan arus sungai sebagai salah satu faktor penyebab kecelakaan. Metode yang digunakan adalah metode lapangan dan permodelan arus sungai. Metode lapangan dilakukan untuk memperoleh data primer berupa data kedalaman, pasang surut serta data arus yang dibutuhkan untuk membuat permodelan pola arus sungai. Permodelan arus sungai menggunakan software HEC-RAS dengan menggabungkan data debit rata-rata, kondisi topografi dan objek jembatan yang berpengaruh. Asumsi aliran sungai Mahakam adalah aliran sungai tak tunak (unsteady flow) dengan debit hulu dan debit hilir sama. Hasil dari penelitian ini, kedalaman di sekitar bawah jembatan berkisar antara -42 sampai -10 m. Hasil pemodelan pola arus melingkar di bawah jembatan dengan kecepatan 0,330 - 0,420 m/s. Kecepatan dan debit rata-rata dari sungai Mahakam berkisar 0,339 m/s dengan debit sebesar 1070,84 m3/s. Hasil simulasi permodelan menunjukkan di pondasi tengah jembatan Mahakam lama dan jembatan Mahakam baru memiliki nilai kecepatan arus yang lebih tinggi daripada sekitarnya. Kecepatan arus ini yang dapat menyebabkan kapal hilang haluan. Pada tiang pondasi tengah jembatan Mahakam lama, daerah dekat fender pengaman jembatan, tersimulasikan arus yang memutar. Pada kasus kecelakaan kapal, pondasi jembatan yang ditabrak berada disisi pengaman fender dan pondasi tengah. Kejadian tersebut bisa disebabkan karena arus memutar tersebut.

Abstract

As a maritime country, Indonesia has a comparative advantage in the potential of marine and fishery resources. The parameters of the distribution of sea surface temperature and the distribution of chlorophyll-a can be used for the determination of the fish catch zone in the Mahakam Delta waters area. By knowing the fishing ground, fishermen can maximize the potentiallity of the fish capture. The purpose of this study was to determine the spatial distribution of ground and chlorophyll-a temperatures and to map potential fishing ground zones. The analysis in this study was determined from the distribution of chlorophyll-a obtained with ATBD 19 MODIS band 10 and 12 algorithms and sea surface temperature distribution on ATBD 25 MODIS bands 20, 31 and 32 using images in March, April, July, September and October 2016. Image processing results obtained, sea surface temperature in March, April, July, September and October averaged 27 ° C to 30 ° C. Only in March the average sea surface temperature has a low temperature. Distribution of chlorophyll-a in 2016 was little identified in September, April and March, whereas in October and July chlorophyll-a was many identified. Determination of high potential catchment zone was having a sea surface temperature of about 27 ° C -30 ° C with high chlorophyll-a value, so that if sea surface temperature and chlorophyll-a conditions were not suitable, it was called a low catchment zone. The low zone of fish catch is scattered to the north and center of the Mahakam delta, as well as in the middle of the makasar strait. The high zone of fish catch is scattered to the south of the Mahakam delta, as well as in the middle of the makasar strait.
