Abstract

Nickel laterite deposit is a result of weathering processes of  ultramafic rocks which carry Ni-Silicate. Generally the deposit is found from tropical to subtropical climates. The aim of this research was to find out the influence of the ground slope to the thickness zone of the nickel laterite based on the cross-section of the drill hole. The research method was to create the cross-section nickel laterite. The data ware obtained from assay data, coordinate, drilling points distribution, and cross-section of the drill hole. From cross-section of the drill hole, the data regarding the level of Ni and Fe were obtained. From the hole id 5A_0171, the lowest Ni level for limonite was 0.19%, and the highest level was 1.17% and for the Fe level, the lowest was 32.13% and the highest was 49.84% with the depth ranging from 0 to 18 metres. The lowest Ni level for the saprolite was 0.79% and the highest was 2.04% whereas for the Fe  level, the lowest was 9.97% and the highest was 15.77% with the depth ranging from 18 to 25 metres. The lowest Ni level for the bedrock was 0.29% and the highest was 0.56% whereas for its Fe level, the lowest was 6.91% and the highest was 8.67% with the depth ranging from 25 to 27 metres. The concluding data for the sloppy areas from the steep to slightslopes was that the limonite zone tended to follow the surface morphology pattern with the thickening occurrence in the steep slopes however the saprolite zone did not follow the surface morphology but it became thick in the steep slopes.

Abstract

One of the most frequent problems in open pit mining methods is the presence of water puddles in the lowest elevation of the pit. This often causesthe delay of production activities.Therefore, it is a need to design a good drainage system planning to deal with it. In this regard, pumps were needed. The aim of this research was to determine the of needed pumps and the best type of pumps to remove water in the pit effectively. This research used maps of mining sequence planningwhich would be then analysed with software Surpac 6.5.1.This was to identifythe width of catchment area. Furthermore, the rainfall data wasanalysed using polygon Thiessen method. The next process is to determine the rainfall plan with Gumbel method. Next was to determine the rainfall intensity plan by using Mononobe equations. Following this was determine the total discharge using rational method. Finally, the process was ended with the determining of the pumps type and pumps spesification to dry the water puddles in the pit. the result indicated that in the sump of the 3rd quarter 2020 with 100 l / sec pumping flow, pumping time 14 hours, total head 76.26 m, recommended pump type is a Multiflo MFC 385 with a rotation speed of recommendation per minute of 1400-1500, and an efficiency of 60% -65%. For 4th quarter sump 2020 with 105l / sec pumping discharge, 20 hour pumping time, total head 105,91 m, recommended type of pump is Multiflo MFC 385 with rotation speed recommendation permenit 1600-1700, with efficiency 60%. For the 1st quarter sump 2021 with a pumping rate of 102 l/sec, the pumping time is 20 hours, total head is 122.26 m, the recommended type of pump is Multiflo MFC 385 with a rotation speed of recommendation per minute 1700-1800, with 50% -60% efficiency. It can be suggested that it is  necessary to add one more pump, Multiflo MFC 385, for the dewatering pit process.

Abstract

Penelitian ini bertujuan menganalisis perbedaan perhitungan volume overburden antara metode survey dan truck count di PT Jaga Aman Sejahtera selama periode Januari-Maret 2025. Data survey menggunakan real time kinematic untuk area pit dan disposal diolah dengan software Surpac 2020 metode cut and fill, sedangkan perhitungan truck count berdasarkan ritase dikali volume vessel. Hasil penelitian menunjukkan volume overburden berdasarkan survey area pit untuk bulan Januari, Februari, dan Maret berturut-turut adalah 140.326,82 m³, 174.175,59 m³, dan 118.678,75 m³, sedangkan berdasarkan survey area disposal adalah 139.715,34 m³, 174.861,58 m³, dan 109.275,08 m³. Volume berdasarkan truck count menunjukkan angka 148.508,00 m³, 194.679,90 m³, dan 133.848,30 m³. Selisih terbesar terjadi antara survey area pit dengan truck count pada bulan Februari sebesar 20.504,31 m³, dan antara survey area disposal dengan truck count pada bulan Maret sebesar 24.573,22 m³. Faktor-faktor penyebab perbedaan meliputi material yang menempel pada bucket excavator, ketidaksesuaian prosedur operasional dimana operator hanya mengisi empat bucket dari standar lima bucket, kurangnya akurasi data survey, material overburden yang kembali ke vessel karena sifat basah dan lengket, distribusi material yang melampaui batas area disposal, dan adanya longsoran di area disposal. Untuk mengatasi permasalahan ini, penelitian merekomendasikan perbaikan prosedur pengambilan data survey, penerapan pengawasan yang lebih ketat dan pemberian batasan area disposal yang jelas.

Abstract

Penelitian ini bertujuan untuk membandingkan karakteristik batubara dari daerah Sorong, Papua Barat Daya, dan Kalimantan Selatan melalui analisis proksimat. Sampel batubara diambil dari Desa Ninjemur, Distrik Moi Segen, Kabupaten Sorong, serta Desa Bilas, Kecamatan Upau, Kabupaten Tabalong, Kalimantan Selatan. Tahapan penelitian meliputi preparasi sampel dengan kominusi hingga ukuran 65 mesh, kemudian dilakukan pengujian laboratorium terhadap kadar air (moisture), kadar abu (ash), zat terbang (volatile matter), karbon tetap (fixed carbon), serta nilai kalor (calorific value). Hasil penelitian menunjukkan bahwa batubara Kalimantan Selatan memiliki kandungan air 9,027%, kandungan abu 43,997%, zat terbang 38,870%, nilai karbon 8,106%, dan nilai kalori 4.408,2 btu/lb. Sementara itu, batubara Sorong memiliki kandungan air 10,054%, kandungan abu 48,011%, zat terbang 37,188%, karbon tetap 4,747%, dan nilai kalori 4.120,2 btu/lb. Berdasarkan klasifikasi ASTM D388, kedua sampel termasuk dalam rank lignit. Meskipun demikian, batubara Kalimantan Selatan menunjukkan kualitas lebih baik dibandingkan Sorong karena memiliki kadar air dan abu lebih rendah, serta nilai kalor lebih tinggi. Oleh karena itu, kedua jenis batubara berpotensi dimanfaatkan sebagai bahan bakar pembangkit listrik, dengan batubara Kalimantan Selatan relatif lebih efisien.
