Abstract

Acid Mine Drainage is one of the environmental problems most frequently faced by the mining industry. Acid mine drainage occurs when sulfide minerals such as pyrite (FeS2) and marcasite (FeS3) are exposed due to mining activities such as dismantling overburden and coal excavation, causing them to react with oxygen and water. Based on the literature review, there are several adsorbents used in the management of acid mine drainage to reduce heavy metals, one of which is coconut fiber. To reduce the impact of acid mine drainage, an effective and efficient management method is needed. An effective method for managing acid mine drainage is to reduce heavy metals using coconut fiber carbon impregnated with a solution of mercaptobenzothianol (MBT). The research results stated that the absorption of heavy metals for the optimum value in coconut fiber carbon impregnated with mercaptobenzothianol (MBT) was 99.93%, however this method was not efficient because it was quite expensive. The most efficient method is the acid mine drainage method using coconut fiber because it is economical and environmentally friendly.

Abstract

Website merupakan salah satu sarana pendidikan di sekolah yang penting dalam mendapatkan informasi terkini terkait pendidikan. Selain menampilkan data profil siswa maupun profil sekolah yang terbaru dan akurat, juga diperlukan untuk Penerimaan Peserta Didik Baru (PPDB) secara online dan perpustakaan digital online. Permasalahan yang sering terjadinya khususnya di SMA Negeri 1 Slawi Jawa Tengah adalah seringnya terjadi pemadaman listrik karena pemeliharaan maupun gangguan yang tak terduga yang menyebabkan aktifitas informasi melalui website sekolah terganggu. Pemadaman listrik yang sering terjadi berakibat rusaknya perangkat server website baik hardware maupun software. Oleh karena itu penelitian ini bertujuan untuk mendesain Pembangkit Listrik Tenaga Surya (PLTS) sebagai catudaya darurat perangkat website. Metode yang digunakan adalah perencanaan kebutuhan daya listrik, perkiraan durasi waktu backup, melakukan perhitungan komponen PLTS, pembuatan sistem kontrol, penginstalasian dan pengujian. Perancangan PLTS untuk daya 600 watt dan durasi backup selama 4 jam didapatkan komponen-komponen PLTS sebesar 600WP panel surya, 30 A solar charger regulator (SCR), 1000 watt Inverter dan 2 x 100 AH 12 volt baterai, sistem kontrol menggunakan relay dan timer. Hasil pengujian yang dilakukan, sistem kontrol dapat bekerja baik secara otomatis (interlock) memindahkan beban dari listrik PLN ke PLTS saat PLN padam, maupun sebaliknya dari PLTS ke PLN. Pengujian siang hari, PLTS dapat mensuplai beban dengan stabil lebih dari 4 jam karena daya untuk menyuplai beban merupakan kontribusi dari baterai dan sinar matahari. Pengujian malam hari, Baterai PLTS dapat mensuplai beban selama 4 jam 4 menit sebelum baterai PLTS habis.

Abstract

Reklamasi adalah kegiatan yang bertujuan memperbaiki atau menata kegunaan lahan yang terganggu akibat kegiatan usaha pertambangan agar dapat berfungsi dan berdaya guna sesuai peruntukannya. Kegiatan reklamasi yang terencana dan berkelanjutan diharapkan lahan bekas tambang dapat digunakan atau dimanfaatkan kembali sebagai lahan pertanian atau kegiatan produktif lainnya sehingga dampak negatif dari kegiatan penambangan dapat berkurang. Dengan melihat pentingnya kegiatan reklamasi ini, sehingga perlu dilakukan evaluasi tingkat keberhasilan reklamasi yang bertujuan untuk mengevaluasi pelaksanaan penatagunaan lahan, pengendalian erosi dan sedimentasi, pelaksanaan revegetasi dan penyelesaian akhir. Erosi merupakan salah satu faktor yang wajib dievaluasi. Hal ini dikarenakan pengendalian erosi dapat mengakibatkan pencemaran lingkungan di luar areal pertambangan karena air limpasan dari areal pertambangan mengalir ke sungai sekitar areal pertambangan, maka dari itu perlu dilakukan klasifikasi erosi guna mengetahui tingkat erosi yang terjadi di area reklamasi-revegetasi Blok 1. Berdasarkan data yang telah diperoleh, maka nilai erosi tanah pertahun di lokasi Reklamasi Blok 1 adalah 70.48 ton/Ha/tahun masuk dalam kategori sedang. Berdasarkan pengamatan di lapangan, hal yang mempengaruhi terjadinya erosi pada area reklamasi Blok 1 karena tidak dibuat bangunan pengendali erosi dan sedimentasi, tidak maksimalnya pertumbuhan tanaman, tidak maksimalnya pertumbuhan cover crops pada area tertentu.

Abstract

Perkembangan penduduk di Kota Cilacap semakin meningkat sejalan dengan perkembangan kota Cilacap sebagai kota industry di Jawa Tengah. Perkembangan pada sektor industri dan usaha di kota Cilacap membawa dampak positif dalam meningkatkan PAD, penyerapan tenaga kerja dan peningkatan perekonomian masyarakat. Dampak negative dari sektor industry antara lain terjadinya polusi udara, berkurangnya interaksi antar warga karena kesibukan dalam bekerja. Kurangnya interaksi masyarakat akan membuat masyarakat cenderung individulais sehingga mudah terjadi perselisihan. Ruang public (taman kota) bisa menjadi solusi untuk mengatasi polusi udara, sebagai wadah kegiatan masyarakat, juga memenuhi RTH kota Cilacap agar mencapai 30%. Perencanaan taman kota di Kota Cilacap ini menekanankan pada pendekatan fungsi social. Desain site plan taman kota terinspirasi dari bentuk bunga wijayakusuma sebagai lambang Kota Cilacap. dilengkapi fasilitas rekreasi olah raga, dan ruang terbuka untuk interaksi warga dalam semua usia.

Abstract

Handika Karya (CV. HK) is a company operating in andesite mining using an open pit mining system located in Kaliduka II Hamlet, Kalirejo Village, Kapanewon Kokap, Kulon Progo Regency, Yogyakarta Special Region Province. The mining operations create noise that can significantly impact the performance of the workers. To address this, it is crucial to effectively monitor and control the noise to optimize performance and safeguard the workers' hearing health. The purpose of this report is to definitively determine the noise level produced by the mining process at CV. Handika Karya, identify the primary sources of noise, and confidently establish the safe time for mining operations in compliance with regulations such as Permenaker No. 5 of 2018 and SNI 7570 of 2010 regarding noise level standards. The research site was precisely divided into three collection points (office, temporary workshop, and monitoring area), and comprehensive data collection was conducted on two different days to accurately reflect the varying mining conditions and intensities. The noise levels due to the mining operations at CV. Handika Karya, based on the worker gathering points, were conclusively determined: 83 dBA in the monitoring area on the first day, 89.3 dBA on the second day; 82.2 dBA in the workshop on the first day, 82.75 dBA on the second day; 76.12 dBA in the office on the first day, and 80.6 dBA on the second day. The noise levels produced by specific mining operations were unequivocally recorded as follows: 95 dBA during the loading operation, 81.9 dBA for 15 seconds during the blasting process, and 101.9 dBA during drilling operations, surpassing the established noise threshold value. To effectively address excessive noise, operators are confidently provided with APT (Active Noise Reduction Earmuffs) with an NRR (Noise Reduction Rating) value of 33 dB, eliminating the need for unnecessary operator changes every 1.28 hours.
