Abstract

Apart from ex-mining land which requires management and rehabilitation using soil microbial communities, reclamation activities require time and technology with high costs and results that are not necessarily effective and efficient. One effective way is to provide organic fertilizer which contains lots of microbes and is able to neutralize soil acidity. This type of research is experimental research with a research design using a Completely Randomized Design (CRD) 4 x 6. The population of this research is all Ruji Nut Plants (Pueraria Javanica) that grow in the PT Mine Wire House area. The main natural coal sampled in this research were 24 Ruji Nut Plants (Pueraria Javanica). The results of this research were that administering NPK solution and Micro Nano Bubbles (MNBs) was proven to help accelerate stem growth, number of leaves, number of leaf branches, root length and increase the biomass of Ruji Nut (Pueraria Javanica) plants in planting media with minimal topsoil. The dosage of Organic NPK Solution and Micro Nano Bubbles (MNBs) for optimal growth of Pueraria javanica plants was in treatment 4 (90 ml), where in treatment 4 the average stem growth, number of leaves, number of leaf branches, root length and plant biomass reached optimal point. So the use of Organic NPK solution using Micro Nano-Bubbles (MNBs) is more effective and environmentally friendly because it is formed from organic materials.

Abstract

Acid Mine Drainage (AMD) or Acidic Acidic Drainage (AAT) is a type of water runoff that happens when certain sulfide minerals in rocks come in contact with water and oxygen, triggering an oxidation process that results in water with acidic properties. To understand more about this phenomenon, a literature review was conducted using relevant keywords on online information sources. The indicators used to measure the level of acidity in mine water include pH, metal concentration, Total Suspended Solid (TSS) or turbidity level, electrical conductivity, sulfate, and sulfuric acid content. High electrical conductivity in mine water usually indicates the presence of metals such as iron (Fe) and manganese (Mn). High levels of manganese (Mn) in water can cause health problems for humans. Moreover, an increase in the concentration of Fe can cause an increase in turbidity or TSS because iron metal can dissolve in air and form solid particles that can cause turbidity. To reduce acidity and environmental pollution, passive or active treatment techniques can be used to neutralize AMD.

Abstract

Abstract. PT Bukit Asam Tbk merupakan sebuah perusahaan pertambangan milik Indonesia, mengkhususkan diri dalam berbagai aspek pertambangan batu bara, termasuk survei umum, eksplorasi, eksploitasi, pengolahan, penyulingan, transportasi, dan perdagangan. Perusahaan ini berkomitmen untuk memelihara fasilitas pelabuhan batu bara guna memenuhi permintaan internal dan eksternal. PT Bukit Asam Tbk menggunakan sistem pertambangan terbuka, dengan menggunakan metode pertambangan kontinu dengan peralatan seperti excavator roda ember (BWE), backhoe, dan truk angkut. Beberapa faktor menghambat operasi optimal sistem pengangkutan, termasuk kondisi jalan angkut yang sempit, yang mengharuskan satu sistem pengangkutan berhenti saat yang lain melewati. Selain itu, kemiringan curam memerlukan kecepatan yang dikurangi untuk navigasi yang aman, dan permukaan jalan yang tidak rata menyebabkan penyebaran material selama transportasi. Untuk mengatasi tantangan ini, evaluasi teknis terhadap geometri jalan angkut diperlukan. Evaluasi ini bertujuan untuk menyederhanakan proses transportasi dan meningkatkan keselamatan operator pengangkutan. Lebar jalan angkut bervariasi antara kondisi lurus dan belok, dengan lebar belokan secara konsisten lebih besar. Desain ini disengaja untuk mengakomodasi deviasi potensial dalam lebar pengangkutan yang disebabkan oleh sudut yang dibentuk oleh roda depan dengan badan truk saat melewati tikungan. Jalan tambang yang ideal mempertahankan kemiringan lintang antara 20 mm/m dan 40 mm/m (2% hingga 4% untuk setiap meter lebar jalan). Kasus khusus jalan AWR Pit 1 melibatkan jalan angkut sepanjang 2.375 meter, tersegmentasi menjadi empat segmen jalan lurus dan satu segmen jalan belok. Beberapa segmen jalan memenuhi nilai kemiringan lintang yang dibutuhkan, sesuai dengan standar jalan setelah perhitungan dan penilaian menyeluruh.

Abstract.  PT. Andalan Artha Primanusa (AAP) is a company engaged in coal production. In November 2022 PT. AAP set an overburden (OB) production target of 817.343 bcm/month, with actual achievement of 453.000 bcm/month or around 55,4% of the planned production target. Based on observations in the field, one of the factors that can hamper production is fleet mismatch (digging equipment waiting for loading) and the unit circulating time is quite high, the XCMG ADT's circulation time is 13.5 minutes, which causing the work of the tool to be less than optimal, as well as other aspects such as unfavorable hauling road conditions so that the operator has to reduce speed which is one of the causes of the high circulation time. The purpose of this research is to analyze the actual unit production, to analyze the value of fleet match factor and to analyze production achievement in overburden removal activities using queuing theory. Based on the results of queuing theory analysis, the number of ADT needed is in accordance with the level of excavator service, namely 7 units of ADT for each fleet and the overburden production is achieved, namely 322.513,6 bcm/month or 39,4% of the target set. Because after setting the queuing theory the production target had not been achieved, the researchers optimized production by using cycle time and the best work efficiency value of the unit, as well as adding 2 units of ADT for each fleet, so that the production of conveyance became 955.839,6 bcm/month or around 116,94% of the target that has been set.Keywords: Match Factor, Overburden, Production, Queuing Theory

Abstract

Kegiatan tambang bawah tanah tidak berhubungan dengan udara luar. Sehingga, resiko kecelakaan di tambang bawah tanah lebih besar dibandingkan tambang terbuka. Pada tambang batubara bawah tanah, terdapat bahaya gas metana yang terbentuk bersamaan dengan keberadaan batubara tersebut. Gas metana bersifat ringan, tidak berwarna, tidak berbau dan tidak berasa. Na mun, itu bisa mengakibatkan ledakan jika dipicu oleh percikan api. Percikan tersebut dapat dipicu oleh hubungan arus listrik atau jatuhan benda-benda logam. Tercatat lebih dari dua belas studi kasus mengenai ledakan gas metana di tambang bawah tanah baik dalam dan luar negeri. Oleh sebab itu diperlukan upaya pencegahan agar gas tersebut tidak meledak dan membahayakan kesela matan pekerja dan alat. Upaya pencegahan dapat dilakukan secara konvensional maupun menggunakan teknologi. Metode konvensional adalah metode lama dimana pekerja melakukan monitoring langsung ke lokasi tambang. Proses itu dilakukan secara berulang-ulang sehingga adanya kecenderungan ketidak-akuratan dalam perhitungan pada alat sensor. Dewasa ini, telah ada teknologi baru yang digunakan yaitu Internet of Things (IoT) dimana terdapat alat sensor yang dipasang di dalam tambang yang terhubung melalui internet sehingga tidak perlu dilakukan pengambilan data secara langsung oleh pekerja di lapangan, justru data tersebut dapat dengan diakses secara langsung. Sehingga, pengambilan keputusan akan adanya potensi bencana dapat segera dilakukan.
