Abstract:
Abstrak: Perkebunan damar yang berada di Kabupaten Pesisir Barat ini adalah perkebunan rakyat yang diusahakan secara turun-temurun, bahkan ada yang mencapai usia 70 tahun dan kawasan Taman Nasional Bukit Barisan Selatan (TNBBS). Menurut Dinas Perindustrian Lampung Barat di Krui terdapat sekitar 1.750.000 pohon damar produktif dengan luas 17.500 ha. Getah damar menjadi komoditas unggulan Lampung dari Hasil Hutan Bukan Kayu (HHBK). Budidaya damar punya dua manfaat sekaligus yaitu pelestarian hutan dan ekonomi. Getah damar mata kucing banyak digunakan untuk bahan emulsi (campuran) pewarna, cat, tinta, aromatik untuk makanan, bahkan juga untuk kosmetik dan lain sebagainya. Metode yang digunakan dalam artikel ini adalah studi dokumentasi dengan menelaah atau mengkaji beberapa teori dan artikel yang berhubungan dengan Damar Mata Kucing. Pihak masyarakat sangat menantikan inovasi dari berbagai pihak yang melibatkan masyarakat dan menguntungkan daya jual damar. Inovasi yang saat ini diharapkan oleh petani adalah alat pengolah damar menjadi bahan setengah jadi sehingga harga jual akan lebih tinggi yang berdampak kepada pendapatan masyarakat. Optimalisasi obyek wisata Hutan damar perlu ditingkatkan dengan memberikan papan informasi edukatif, sejarah dan gambar penunjang lainnya. This damar plantation in Pesisir Barat Regency is a community plantation that has been cultivated from generation to generation, some even reached the age of 70 and the Bukit Barisan Selatan National Park (TNBBS) area. According to the West Lampung Industry Service in Krui there are about 1,750,000 productive resin trees covering an area of ​​17,500 ha. Dammar sap is Lampung's leading commodity from Non-Timber Forest Products (HHBK). The cultivation of resin has two benefits, namely forest conservation and the economy. Cat's eye resin is widely used for emulsion (mixture) of dyes, paints, inks, aromatics for food, even for cosmetics and so on. The method used in this article is a documentary study by examining or examining several theories and articles related to cat's eye resin. The community is looking forward to innovations from various parties that involve the community and benefit the selling power of resin. The innovation that is currently expected by farmers is a means of processing resin into semi-finished materials so that the selling price will be higher which will have an impact on people's income. Optimization of the Damar Forest tourism object needs to be improved by providing educational information boards, history and other supporting images.

Abstract:
Abstrak: Bakteri pereduksi sulfat atau Sulfate-reducing bacteria (SRB) adalah jenis bakteri obligat anaerob kemolitrotof memanfaatkan donor electron H2. Kemampuan SRB mereduksi sulfat menjadi sulfida mampu mengendapkan logam toksik meliputi Cd, Cu, dan Zn sebagai logam sulfida. SRB memerlukan substrat organik seperti asam piruvat yang dihasilkan oleh aktivitas anaerob lainnya. Mekanisme SRB dalam melakukan reduksi sulfat, sulfat digunakan sebagai sumber energi sebagai akseptor elektron dan menggunakan sumber karbon (C) sebagai donor elekton dalam metabolisme dan bahan penyusun sel. Pada kondisi anaerob bahan organik akan berperan sebagai donor elektron. Pembentukan senyawa sulfida melalui proses reduksi yang ditandai oleh penambahan elektron dari bahan organik yang menyebabkan turunnya konsentrasi sulfat dan naiknya pH lingkungan. SRB pada kawah air panas nirwana ini hidup secara anaerob pada suhu lingkungan 600C - 1000C dengan pH 7,4 tingkat kekeruhan air cukup keruh dan kandungan air yang mengandung blerang dengan indikator bau seperti telur busuk dan lingkungan sekitar terdiri dari sedimen batu kapur. Abstract : Sulfate-reducing bacteria (BPS) is a type of chemolithotroph obligate anaerobic bacteria that utilize H2 electron donors. The ability of BPS to reduce sulfate to sulfide is able to precipitate toxic metals including Cd, Cu, and Zn as metal sulfides. BPS requires organic substrates such as pyruvic acid which is produced by other anaerobic activities. The BPS mechanism in reducing sulfate, sulfate is used as an energy source as an electron acceptor and uses a carbon source (C) as an electron donor in metabolism and cell building material. Under anaerobic conditions, organic matter will act as an electron donor. The formation of sulfide compounds through a reduction process is characterized by the addition of electrons from organic matter which causes a decrease in sulfate concentration and an increase in environmental pH. BPS in this nirvana hot spring crater lives anaerobically at an environmental temperature of 600C - 1000C with a pH of 7.4 the level of turbidity of the water is quite cloudy and the water content contains sulfur with an indicator of smell like rotten eggs and the surrounding environment consists of limestone sediments
