Abstract

Industri pertambangan di Indonesia memegang peranan penting sebagai sumber pendapatan negara dan bagian dari kemajuan industri suatu bangsa. Mayoritas industri pertambangan di Indonesia adalah tambang terbuka. Salah satu faktor cuaca yang bisa menjadi hambatan dalam penambangan terbuka ialah curah hujan. Penelitian ini berfokus pada pemodelan data dari curah hujan, jam kerja, dan hasil produksi. Pada penelitian ini menggunakan Algoritma Artificial Neural Network Backpropagation dengan input layer yang terdiri dari dua neuron, satu hidden layer dengan dua neuron, serta satu output layer. Data curah hujan, jam kerja, dan hasil produksi di-training sehingga menghasilkan sebuah model yang nantinya model ini akan digunakan untuk memprediksi nilai untuk hasil produksi. Untuk pengujian model, penelitian ini menggunakan dua parameter, yaitu learning rate dan epoch. Dari 90 kali pengujian didapatkan model terbaik dengan nilai learning rate bernilai 0,3 dan epoch bernilai 1000 yang menghasilkan error RMSE sebesar 0,004838259401280330

Abstract

Identification and interpretation of landscape lineaments and measurements of geological structural components in rock outcrops have been carried out in order to reveal the development of rock sequence deformation in the study area. This research was conducted in Tanjung Kurung Village and its surroundings. The regional observation area is included in the Manna Enggano Sheet Geological Map (Amin, T, C. et al, 1993), while tectonically it is located in the Bengkulu basin which previous researchers categorized as a fore-arc basin (Sapiie et al ., 2015). This study uses two approaches, namely lineament analysis with national digital elevation model (DEMNas) image interpretation and surface geological mapping with observation of rock outcrops or structures. The DEMNas image used in this research has been accessed from https://tanahair.indonesia.go.id/portal-web which is owned by the Geospatial Information Agency (BIG). The geological structure of the Bengkulu Basin is divided into two general directions, namely the North-West-Southeast and North-East-Southwest directions. Structures that trend northwest-southeast are the Tanjung Sakti fault and the Ketaun fault. These faults are directly related to the Semangko Fault pattern and the Mentawai Fault pattern (Yulihanto et al., 1995).

Abstract

The Mining industry in Indonesia plays a vital role as a source of state income and an integral part of the industrial progress of the nation. The majority of the mining industry in Indonesia employs open-pit mining. One of the weather factors that can be an obstacle in open-pit mining is rainfall. Therefore, this research focused on modelling data from rainfall, working hours and production outcomes. It applied the Artificial Neural Network algorithm with an input layer consisting of two neurons, a hidden layer with two neurons, and an output layer. The data on Rainfall working hours, and production results were trained to produce a model that, later on, will be used to predict the value of production results. For model testing, this study uses two parameters, namely learning rate and epoch. From 90 times of testing, the best model was obtained with a learning rate value of 0.3 and an epoch of 1000 which resulted in an RMSE error of 0.004838259401280330
