Abstract

ABSTRAK Di Indonesia, operasional penambangan batubara umumnya melibatkan tenaga kerja dengan jumlah yang besar. Kondisi ini memberikan tantangan tersendiri dalam pengelolaan dampak lingkungan yang berpotensi timbul dari aktivitas manusia. Salah satu potensi tersebut yakni air limbah domestik. Air limbah domestik merupakan air limbah yang berasal dari aktivitas hidup sehari-hari manusia yang berhubungan dengan pemakaian air. Di area operasional pertambangan, air limbah domestik dapat timbul dari area pemukiman karyawan dan perkantoran. Karena potensi dampaknya terhadap lingkungan, air limbah domestik harus diolah sebelum dialirkan ke badan air penerima. Sejak tahun 1990an, diawal operasi penambangan, Kaltim Prima Coal (KPC) telah membangun dan mengoperasiokan Instalasi Pengolahan Air Limbah Domestik (IPALD) untuk mengolah air limbah domestik yang bersumber dari pemukiman karyawan dan perkantoran. Terdapat 12 IPALD dengan teknologi lumpur aktif yang beroperasi di area KPC. Lumpur aktif merupakan salah satu teknologi pengolahan air limbah domestik dengan memanfaatkan peran bakteri aerob untuk mendegradasi material organik yang terkandung didalam air limbah domestik. Makalah ini disajikan untuk mendeskripsikan performa teknologi lumpur aktif yang digunakan dalam IPALD KPC dan tantangan yang dihadapi dalam pengoperasiannya. Salah satu tantangan yang dihadapi yakni pemenuhan baku mutu yang tertuang dalam Keputusan Menteri Lingkungan Hidup dan Kehutanan No. P. 68 Tahun 2016 tentang Baku Mutu Air Limbah Domestik. Baku mutu terbaru mengatur konsentrasi efluen IPALD lebih ketat dari sebelumnya dan terdapat paramater baru, diantaranya amoniak yang memerlukan perhatian dalam pengoperasian IPALD. Kata kunci: air limbah domestik, lumpur aktif, ipald  ABSTRACT In Indonesia, coal mining operations generally involve a huge number of workers. This condition causes its own challenges in managing environmental impacts that potentially generated from human activities. One of them is domestic wastewater. Domestic waste water is waste water that comes from activities of daily living of humans related to water usage. In mining operations, domestic wastewater is generated from office and residential areas. Because of the potential impact on the environment, domestic wastewater must be treated before flowing to natural water bodies. Since the beginning of mining operations in 1990s, PT Kaltim Prima Coal has been building and operating Domestic Wastewater Treatment Plant (IPALD) to treat domestic wastewater resulting from offices and residential areas. There are 12 IPALDs with activated sludge technology operating in the KPC area. Active sludge is one of the domestic wastewater treatment technologies by utilizing the role of aerobic bacteria to degrade organic material contained in domestic wastewater. This paper is presented to describe the performance of activated sludge technology used in the KPC’s IPALD and the challenges faced in its operation. One of the challenges faced is the fulfillment of water quality standards in Minister of Environment and Forestry Decree No. P. 68 of 2016 concerning Domestic Wastewater Quality Standards. The latest quality standards regulate the effluent concentration of IPALD more stringent than before and there are new parameters, including ammonia which requires attention in the operation of IPALD. Keywords: domestic waste water, activated sludge, ipald

Abstract

The waters of the Bengalon River, Sangatta and surrounding areas are affected by community activities as well as coal mining and oil palm plantations. Fish are one of the aquatic biota affected by these activities. The unavailability of river fish species data is a particular concern in evaluating the condition of river waters. The availability of fish species data is considered important for decision-making considerations that will be applied in an area. As a sustainability effort, monitoring, identification and inventory of river fish in the East Kutai Regency area were carried out. This research was conducted in November 2021-May 2022 in Bengalon River, Sangatta and surrounding areas. Fish identification was carried out at the Hydroceanography Laboratory, Faculty of Fisheries and Marine Science, Mulawarman University. Fish data were analyzed descriptively. Based on the research data, rivers in East Kutai district are dominated by the Cyprinidae family. A total of 43 fish species were identified, 10 of which were marine fish species, generally fishes that live around estuaries (brackish water), including species that live in the sea.
