Abstract

Investment analysis needs to be done to determine the feasibility of a project from an economic perspective. In this research, an investment analysis were applied in a coal mine project. The analysis were considering the results of NPV and IRR. NPV is the result of subtracting discounted costs [8]. IRR is an interest rate that shows the net present value is equal to the total amount of business investment [9]. The methods used in the analysis are the conventional method and the Fuzzy method. Conventional method is done by using NPV and IRR formula in Ms.Excel while Matlab for Fuzzy. The Fuzzy method apply a membership functions, namely triangular fuzzy number. The results of the analysis using conventional methods show an NPV value of $ 14,900,691 or IDR 223 Million with an IRR value of 69.8%. The results of the analysis using the fuzzy method with triangular membership functions showed the NPV values of IDR 232 Million and IRR 40.1 %. From the analysis, it can be seen that the fuzzy method is able to produce a larger NPV but a smaller IRR value whose value is close to conventional methods with the same input variables. So it can be concluded that the fuzzy method is quite well applied in investment analysis and it can help for the final decision of a project

Abstract

Luapan air ke tambang terbuka merupakan tantangan signifikan dalam operasi penambangan, karena berpotensi menyebabkan gangguan teknis dan peningkatan biaya. Tujuan dari studi ini adalah untuk memperkirakan total aliran masuk tambang melalui dua pendekatan. Pertama, Metode Rasional digunakan untuk menghitung limpasan permukaan. Kedua, Hukum Darcy digunakan untuk memperkirakan rembesan air tanah. Data yang digunakan mencakup parameter seperti curah hujan maksimum, daerah tangkapan air, koefisien limpasan, konduktivitas hidrolik, gradien hidrolik, dan luas penampang akuifer. Analisis menghasilkan debit limpasan permukaan maksimum sebesar 0,81 m³/detik dan rembesan air tanah sebesar 0,16 m³/detik. Total debit yang diperkirakan ke lantai tambang adalah 0,778 m³/detik, sedangkan total potensi ke seluruh area tambang mencapai 0,97 m³/detik. Perkiraan ini dapat menjadi dasar untuk perencanaan sistem drainase tambang yang efektif yang mendukung keberlanjutan operasional.

Abstract

Landslides in tropical regions are often triggered by intense rainfall, causing significant impacts. This study assesses the feasibility of rainfall thresholds for landslide early warning in Kapanewon Samigaluh, Kulon Progo. The objectives include characterizing the rainfall regime, testing the relationship between rainfall and landslide events, evaluating spatial consistency with the landslide hazard map, and establishing and verifying operational thresholds. Landslide data from the BPBD and daily rainfall data from BMKG were processed by aligning the dates and performing quality checks, followed by quantitative analysis. The number of landslide events analysed was 197, with rainfall data collected from a single measurement station. Thresholds were set using the median approach for daily rainfall (CH0) and three-day accumulation (CH−2) from the 2014–2023 series. Verification was conducted on 213 days of the 2024 rainy season using Proportion Correct. Characterization shows a consistent monsoonal pattern with notable interannual variability. A positive tendency is observed between annual rainfall accumulation and landslide frequency. Spatially, around 93% of events occur in high-hazard zones. The median-based thresholds obtained are 31 mm for CH0 and 81 mm for CH−2. Operational verification results in PC values of 84.0% for CH0 and 83.6% for CH−2, indicating acceptable performance. Physically, the intensity of rainfall on event days effectively distinguishes landslide from nonlandslide days, while three-day rainfall accumulation increases risk through soil saturation. These findings support the implementation of locally calibrated thresholds for strengthening early warning, with a focus on monitoring during the rainy season. However, the potential for false alarms related to geological conditions and land-use variability may affect model accuracy. Furthermore, periodic recalibration of thresholds is necessary to address uncertainties resulting from changing hydrometeorological conditions and land-use dynamics.

Abstract

Area penambangan PT PPA site PT MLP tepatnya di Blok Sawit terdapat genangan di Jalan. Masalah tersebut muncul didukung dengan fakta bahwa intensitas hujan di lokasi penelitian tergolong lebat (25,61 mm/jam). Saluran terbuka menjadi salah satu infrastruktur paling penting untuk mengalirkan air limpasan. Namun terdapat lokasi yang belum terdapat saluran terbuka dan kapasitas saluran yang belum memadai. Hal tersebut menandakan sistem penyaliran tambang yang ada belum optimal. Oleh karena itu, diperlukan kajian dan rancangan saluran terbuka area Blok Sawit. Penelitian ini, estimasi debit aliran air permukaan menggunakan metode rasional dengan memperhatikan intensitas hujan (mononobe), karakteristik DTH, dan koefisien limpasan (Gautama). Nilai debit air limpasan, digunakan acuan dalam mengkaji dan merancang dimensi saluran terbuka (persamaan manning). Lalu dilakukan simulasi potensi genangan di HEC-RAS sebagai bentuk validasi atas dimensi saluran hasil perhitungan. Didapatkan nilai intensitas curah hujan sebesar 25,61 mm/jam dengan PUH 2 tahun, serta resiko hidrologi 88%. Berdasarkan perhitungan menggunakan persamaan manning dan simulasi di HEC-RAS diperlukan rancangan pada saluran terbuka 1 di DTH 4 serta perluasan pada saluran terbuka 4 di DTH 6. Adapun pada saluran terbuka 2 dan 3 kapasitas secara aktual sudah memadai.

Abstract

Information technology has emerged to make various activities easier. One of the important roles of information technology is in providing disaster information. River Care Communities (KPS) which are currently spread across several regions in Indonesia, one of which is River Care Communities Opak Gajah Wong. River Care Communities have an important role in helping reduce disaster risks along river flows. There are various kinds of events that have the potential to cause disasters along river flows, including accumulation of rubbish, landslides on river walls, narrowing and shallowing of rivers, rising water discharge above normal limits and the growth of wild plants that can obstruct river flow. Currently the River Care Community only reports its activities conventionally and has not maximized the existence of information technology. With this conventional method, the delivery of incident reports along the river which is their area of ​​activity is often late, the coordinates are inaccurate and confusing because they are not accompanied by visual images. The conventional pattern of submitting reports means that these reports are too late to be followed up by the relevant agencies and are often simply overlooked. To answer the problems mentioned above, the author conducted research by developing an E-Report application based on Android mobile application using the prototyping method. Currently, there are already several similar complaint applications, but they are not specific to problems that exist along the river flow. The form of complaints and reports in river basins has unique characteristics, where the reporter must enter certain values ​​to determine the level of urgency of the report. With this application, it is hoped that every report from River Care Communities Opak Gajah Wong can be conveyed in real time and immediately receive follow-up from the relevant agencies.

Abstract

Abstrak Kajian mengenai pengaruh perubahan daerah tangkapan hujan akibat pengembangan disposal terhadap kebutuhan kapasitas sump masih sangat terbatas, khususnya pada tambang emas terbuka di Indonesia. Penelitian terdahulu umumnya mengkaji aspek sistem penyaliran, sedimentasi, dan hidrologi disposal secara terpisah, sehingga belum terdapat kajian yang mengintegrasikan perubahan daerah tangkapan hujan akibat ekspansi disposal dengan evaluasi kebutuhan kapasitas sump secara komprehensif. Penelitian ini bertujuan menganalisis pengaruh perubahan daerah tangkapan hujan akibat pengembangan disposal terhadap debit limpasan, potensi sedimentasi, dan kebutuhan kapasitas sump Penelitian dilakukan menggunakan metode kuantitatif deskriptif berdasarkan data curah hujan periode 2016–2025. Curah hujan rencana dihitung menggunakan distribusi Gumbel, intensitas hujan dengan metode Mononobe, dan debit limpasan dengan metode Rasional. Daerah tangkapan hujan didelineasi menggunakan data Digital Elevation Model (DEM) melalui perangkat lunak Global Mapper, sedangkan potensi erosi dan sedimentasi dihitung menggunakan metode USLE dan pendekatan Sediment Delivery Ratio (SDR). Analisis menunjukkan bahwa pengembangan disposal menyebabkan perubahan distribusi daerah tangkapan hujan yang mengakibatkan dominasi aliran menuju sump eksisting dengan debit limpasan sebesar 16,81 m³/detik, dibandingkan 8,04 m³/detik pada sump baru. Potensi sedimentasi tahunan pada sump eksisting dan sump baru masing-masing sebesar 11.631 ton/tahun dan 8.189 ton/tahun. Perubahan daerah tangkapan hujan tersebut mengakibatkan kebutuhan kapasitas tampungan sebesar 218.856 m³ untuk sump eksisting dan 51.463 m³ untuk sump baru. Kebaruan penelitian ini terletak pada pendekatan integratif yang menghubungkan secara kuantitatif perubahan daerah tangkapan hujan akibat ekspansi disposal dengan evaluasi kebutuhan kapasitas sump sebagai acuan teknis perencanaan sistem penyaliran tambang yang adaptif terhadap perubahan topografi.
