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.

Abstract

Penelitian ini bertujuan untuk menganalisis losstime pada kegiatan produksi pengupasan tanah penutup di Pit Diamond PT Ceria Jasatambang Pratama. Metode penelitian meliputi pengumpulan data primer berupa delay time, cycle time, serta observasi lapangan, dan data sekunder seperti laporan harian produksi, jam kerja, spesifikasi alat, serta catatan losstime. Data diolah menggunakan Microsoft Excel dengan pendekatan perhitungan produktivitas berdasarkan kapasitas bucket, swell factor, fill factor, efisiensi kerja, dan cycle time. Hasil penelitian menunjukkan bahwa losstime utama yang menghambat produksi pada Fleet 1 adalah waktu istirahat yang terlalu cepat, sedangkan pada Fleet 2 adalah keterlambatan mulai bekerja setelah istirahat. Total losstime yang terjadi pada Maret 2025 sebesar 65 jam untuk Fleet 1 dan 60 jam untuk Fleet 2. Efisiensi kerja alat gali muat rata-rata mencapai 64%, sedangkan alat angkut 72%. Nilai produktivitas menunjukkan bahwa setelah mempertimbangkan losstime, produksi Fleet 1 adalah 101,53 ton/jam atau 4.129,12 ton/minggu, sedangkan Fleet 2 mencapai 176,25 ton/jam atau 7.402,5 ton/minggu. Temuan ini menegaskan bahwa losstime memiliki pengaruh signifikan terhadap pencapaian target produksi, sehingga diperlukan upaya pengendalian melalui pengawasan disiplin kerja, penerapan pembicaraan lima menit (P5M), pemeriksaan harian (P2H), dan pengelolaan aktivitas pendukung seperti pengisian bahan bakar.

Abstract

Penelitian ini menganalisis dan merancang geometri jalan tambang di PT Pancaran Surya Abadi, Kabupaten Kutai Kartanegara, dengan memperhatikan standar teknis agar mendukung keselamatan dan efisiensi operasional alat angkut. Studi dilakukan dengan pengumpulan data lapangan meliputi lebar jalan lurus, lebar jalan tikungan, kemiringan jalan (grade), superelevasi, dan cross slope. Analisis desain mengacu pada pedoman AASHTO dan Keputusan Menteri ESDM No.1827/K/30/MEM/2018, serta memanfaatkan perangkat lunak Surpac untuk pemodelan dan perencanaan jalan tambang. Hasil evaluasi menunjukkan bahwa lebar jalan lurus aktual berkisar antara 10 sampai 13,84 meter, sedangkan lebar jalan tikungan bervariasi antara 10,95 sampai 20 meter. Kemiringan jalan aktual berada di antara 7,3% sampai 10,5%, namun sepanjang segmen pengukuran tidak ditemukan nilai superelevasi maupun cross slope yang berarti, karena elevasi sisi kiri, tengah, dan kanan jalan relatif sama. Kondisi tersebut mengindikasikan perlunya perbaikan dalam desain geometri jalan tambang untuk memastikan drainase efektif dan keselamatan alat angkut saat beroperasi, terutama pada tikungan dan area rawan banjir. Studi ini menyimpulkan bahwa jalan tambang di PT Pancaran Surya Abadi masih memerlukan penyesuaian agar memenuhi standar geometri yang ditetapkan, khususnya pada aspek kemiringan melintang dan superelevasi. Rekomendasi teknis disampaikan untuk meningkatkan umur jalan, mengurangi risiko kecelakaan, serta mendukung produktivitas tambang di wilayah dengan topografi dan kondisi iklim tropis seperti Kutai Kartanegara.
