Abstract

The research was motivated by the implementation of Complete Systematic Land Registration (PTSL) activities in Lendiang Liang Nayuq Village in 2022 to provide guarantees of legal certainty or rights to land owned by the community. PTSL activities have an impact on land use in Lendiang Liang Nayuq Village. Thus, it is necessary to utilize the results of these measurements to map land use. The aim of this research is to determine the area of Lendiang Liang Nayuq Village, the area of land that has been developed in the form of settlements, public facilities, plantations, and Cultivation Rights (HGU) in Lendiang Liang Nayuq Village, Siluq Nurai District, West Kutai Regency. The method used in this research is direct measurements in the field using GPS Geodetic HI-target v60 to obtain measuring field coordinates in the form of land use and village administrative boundaries. Next, digitization is carried out using GIS software. The results of this research showed that the number of fields measuring PTSL 2022 results in Lendiang Liang Nayuq Village, Siluq Ngurai District, West Kutai Regency was 314 fields, consisting of housing, public facilities, and plantations. Meanwhile, the land use area is 0.03% of the built-up land area in the form of settlements, 0.66% plantations, 0.09% public facilities, 25.51% Cultivation Rights and the remaining 73.71% is non-PTSL 2022 land.

Abstract

Coal is a mineral resource with high economic value. Demand for coal commodities is increasing to meet energy needs. Therefore, calculating coal reserves is an important thing to do in coal exploration activities. Coal that has been mined will be stacked in a storage area (stockpile) or temporary storage (temporary stock) before being transported to consumers. Periodic volume monitoring is one of the most important things in stockpile management control which aims to determine the volume of coal in the stockpile. The cut and fill method is a coal volume calculation method that is often used in mining activities by calculating the area of ​​two cross-sections and the distance between the top and bottom cross-sections. The data used in this research are coordinate data (x, y, and z) stock taking measurements, base/bedding data (base), weighing data, density data (density), and ortho photos of Port SBJ obtained indirectly from the location research at PT Insani Baraperkasa, Tani Bhakti Village, Loa Janan District, Kutai Kartanegara Regency. The results of this research are the total BCM (Bank Cubic Meter) volume of the coal stockpile, which is then converted into tonnage value (kg/m³), namely by multiplying the density (kg/m³) of coal to obtain the tonnage value in Raw Coal Room 1, namely 33,012.52 (tons) and the Crushed Coal tonnage is 8,080.07 (tons). The tonnage value adds up to 41,092.59 (tons) in the SBJ Port stockpile tonnage for the period February 2022.

Abstract

This study aims to compare and evaluate the accuracy of land area measurement through aerial photo identification with direct field/ terestrial measurements using Geodetic GPS. This is useful for determining the most efficient and accurate method to support the acceleration of the Complete Systematic Land Registration (PTSL) program. Based on the measurement activities and data analysis, the largest coordinate discrepancy between aerial photo identification and direct measurement using Geodetic GPS was found in land parcel 10, with a difference of 0.88031550. The smallest discrepancy was observed in land parcel 7, with a difference of 0.06694568. The total coordinate discrepancy across the measurement of 10 land parcels was 3.92, with an average discrepancy of 0.35. The Root Mean Square Error (RMSE) value was 0.59. Furthermore, the field measurement results showed that direct field measurement using Geodetic GPS produced highly accurate land area data. The discrepancy between the land area proposed by the applicant and the direct measurement results had an average difference of only 0.7 m². Meanwhile, the measurement results of land area through aerial photo identification showed a larger average discrepancy compared to the land area proposed by PTSL applicants, with an average difference of 10.8 m².

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

Tembang writers typically employ words that are not literal but rather words have figurative meanings. One of those is metaphor. This study aims to analyze metaphors in Nyidham Sari songs and reveal their role in conveying cultural values and moral messages in language learning, as well as understand how traditional Javanese songs can serve as an educational tool to transmit knowledge and cultural values to contemporary learners. The data of the research are metaphors within the Nyidham Sari tembang. To analyse the data the researcher identified metaphors to understand the metaphor meaning and the function in the context of the tembang. This study employs the basic theory of the Conceptual Metaphor by Lakoff and Johnson. This study shows that Nyidham Sari tembang uses natural metaphors, journey metaphors, and cultural value metaphors to describe abstract concepts and convey deep messages. The research results indicate that metaphors in Nyidham Sari tembang play an important role in conveying cultural values and moral messages. The result of this study also has implication on language teaching, namely, teaching metaphor, interpretation skill development, teaching material, and critical thinking development. Finally, this study is expected to inspire other researchers who interest to explore metaphors in different cultural.

Abstract

This study was conducted to determine land cover changes in Baubau City, Southeast Sulawesi Province, in 2015, 2019, and 2023. As a center of economic and social activity, Baubau City is experiencing rapid regional development, necessitating an analysis of changes in its land use. This study also aims to identify the types of land that have undergone changes and the factors influencing these changes. The method used in this study is spatial analysis using Landsat 8 satellite imagery with a supervised classification technique using the Support Vector Machine (SVM) algorithm. The land cover types analyzed include clouds, forest land, agricultural land, open land, and settlements. The data used is Landsat 8 satellite imagery from 2015, 2019, and 2023. The imagery data was then processed using ArcGIS software to identify and map changes that occurred between years. The research process included data collection, image processing, classification, change analysis, and map creation. The results of the study indicate that from 2015 to 2023, there were significant changes in land cover in Baubau City. In 2019, some areas were covered by clouds, affecting land interpretation results, but a trend of change was still visible. Agricultural land showed a decreasing trend in area from 76.99 km² in 2015 to 68.51 km² in 2019, and continued to shrink to 34.53 km² in 2023, so that agricultural land showed a narrowing. In 2015, the area of residential land was recorded at 21.51 km², then shrank to 14.01 km² in 2019, and increased sharply to 36.33 km² in 2023, so that residential land showed an increase. Forest land has consistently increased, from 116.16 km² in 2015 to 121.09 km² in 2019, and continues to grow to 138.95 km² in 2023, resulting in forest land shrinking. Based on these results, it can be concluded that the direction of Baubau City's development tends towards residential expansion, displacing agricultural land. Therefore, sustainable spatial management is needed to maintain ecological functions.
