Abstract

Penimbunan kembali tanah penutup lahan bukaan bekas tambang harus dilakukan secara matang dan terencana, perencanaan penimbunan mencakup tahapan – tahapan yang sequential dan terukur jumlah volume dan waktunya. Hal ini dilakukan agar kegiatan penimbunan dapat meminimalisir dampak terhadap lingkungan serta menyesuaikan pada Peraturan Pemerintah (PP) No. 78 Tahun 2010 tentang Reklamasi dan Pascatambang. Perencanaan sequence backfill perlu mengetahui luas area penimbunan, elevasi awal sebelum penimbunan, kinerja alat yang digunakan untuk penimbunan, volume material penimbunan yang tersedia serta jam bekerja perusahaan yang tersedia. Pengolahan data dilakukan dengan menggunakan software Surpac dan AutoCAD. Hasil dari analisis yang dilakukan maka produktivitas alat penimbunan berupa 2 excavator adalah 440,77 LCM/Jam dan dibuat 3 sequence penimbunan backfill yang total volume penimbunannya adalah 143.807 LCM (Loose Cubic Meters) dan total volume topsoil 8.658,16 LCM . Masing – masing sequence terdiri dari, besar volume sequence I 52.418 LCM, besar volume sequence II 52.375 LCM, dan besar volume sequence III 39.014 LCM. Dengan jumlah waktu penimbunan 19,15 hari.

Abstract

PT Antareja Mahada Makmur Jobsite MHU berlokasi di Loa Kulu, Kutai Kartanegara, Kalimantan Timur. Berdasarkan penelitian di lapangan terdapat banyak segmen jalan yang memiliki grade yang tinggi dan rolling resistance yang besar, sehingga produktivitas dan konsumsi bahan bakar tidak optimal. Tujuan dari penelitian ini adalah untuk memperbaiki geometri serta kondisi jalan angkut agar produktivitas dan konsumsi bahan bakar lebih optimal, serta mengetahui pengaruh geoemtri dan kondisi jalan angkut terhadap produktivitas dan konsumsi bahan bakar hauler. Penelitian ini menggunakan metode analisis kuantitatif, data primer yang diambil adalah cycle time hauler, geometri jalan angkut, uji menggunakan Dynamic Cone Penetrometer, dan data amblasan. Perhitungan produktivitas alat angkut dihitung dengan mengetahui berapa lama siklus dari alat angkut, sedangkan perhitungan konsumsi bahan bakar dilakukan menggunakan parameter load factor dengan pendekatan Rimpull. Produktivitas alat angkut pada lokasi penelitian sebesar 102.33 BCM/jam dan konsumsi bahan bakar alat angkut sebesar 70.3 liter/jam. Setelah dilakukan perbaikan yaitu membuat jalan Integritas baru dengan lebar jalan sesuai standar (30 meter) dan grade lebih landai, serta rolling resistance < 2%. Produktivitas alat angkut menjadi bertambah dan konsumsi bahan bakar menurun. Berdasarkan perhitungan produktivitas alat angkut setelah perbaikan menjadi 111.2 BCM/jam dan konsumsi bahan bakar hauler menjadi 59.4 BCM/jam. Hal tersebut membuat fuel ratio alat angkut juga ikut menurun yaitu menjadi 0.53 L/BCM.

Abstract

This research was conducted because the material absorption capacity needs to be maximized, so it is necessary to make a mining slope geometry with an optimal safety factor value so that there is no potential for landslides in the research area. The method used is the morgenstern price method, this method was chosen because it has considered the stability of moments and forces.The actual slope geometry that has not been tested for safety needs to be changed. The physical and mechanical properties data collection is processed to produce a geometric model with a safety factor in accordance with applicable regulations. The actual slope geometry of the Cijurey block is 20m with a slope of 85o, 8m with a slope of 88o, 5m with a slope of 83o and 4m with a slope of 85o with a safety factor value of 1.01. A geometric change was made with a slope height of 6 m and a ladder width of 3m which was made multi-level with an overall angle of 80o having a safety factor of 1.302 which means that it has met the slope safety criteria.Keywords: safety factor, geometry, slope

Abstract

Effective software development planning is vital across various industries, and inadequate planning can lead to project failures. A key part of this planning is accurately estimating effort and costs, which is crucial for staying within budget and meeting deadlines. This research compares two methods – Use Case Point Activity Based Costing (with 21 complexity factors) and Adjusted Function Point (with 16 complexity factors) – for estimating costs versus actual values. The analysis reveals that the Use Case Point method had a 23.52% deviation from actual costs, while the Adjusted Function Point method had a 33.35% deviation. These findings provide essential reference points during software project planning, ensuring estimates closely align with actual values based on project-specific attributes. This deviation underscores the importance of precision and selecting appropriate methodologies tailored to each project’s unique characteristics. Ultimately, this research equips businesses and project managers with a robust financial prudence framework and enhances the likelihood of project success.
