BIOPROSES PENGURAIAN LIMBAH CAIR BUANGAN INDUSTRI PANGAN DAN NON-PANGAN BERBASIS BIOSURFAKTAN
Full text linkBiosurfactants are microbial metabolites that may be utilized to replace synthetic chemical surfactant in overcoming the problem of industrial wastewater pollution. Indications of the presence of biosurfactant activity may be determined through measurement of emulsification and enzymatic activity of the tested microorganisms on their growth media, which is indicated by decreasing the BOD and COD of the tested growth media containing wastewater material as an inducer added to the microbial growth medium. This research was conducted to examine several potential microbial isolates that produce biosurfactants on growth media containing mixed waste water. The results showed that some of the microbial cultures tested showed the potential to produce biosurfactants as indicated by the emulsification and enzymatic activity of the tested microbial culture. Trial on mixed industrial wastewater showed that the tested biosurfactants were able to reduce the levels of BOD (440-1300 mg/l) and COD (1240-1760 mg/l) of the wastewater samples up to low BOD levels (82 mg/l) and COD (116 mg/l), respectively, thus that it meets the requirements of the established wastewater quality standards according to the Indonesian Standard regarding with the respective BOD (50-100 mg/l, 06-6989.9-2004 SNI) and COD (100-250 mg /l, 06-6989.2-2004 SNI).Key words : biosurfactant, emulsification, microbial enzyme, wastewater, BOD, COD
Inventarisasi, Hubungan Kekerabatan, dan Pemanfaatan Bambu (Poaceae: Bambusoideae) di Kawasan Hutan Desa Tompobulu Kabupaten Pangkep
Full text linkAbstract. An inventory of bamboo species in various regions is carried out to explore its potential in the local community so that each type can be utilized and conserved optimally. This study aims to determine the types of bamboo found in Tompobulu Village, the status of kinship between species, and the benefits of bamboo for people's lives. Exploration has been carried out using the tracking method. The species found were identified morphologically on the culm, culm sheath, branches, and leaves. Data were analyzed quantitatively using cluster analysis with UPGMA. PCA was used to determine the role of each morphological character in accession grouping. This study identified eight bamboo species from five genera, namely Bambusa striata, B. vulgaris, Dendrocalamus asper, Gigantochloa atter, Gigantochloa sp., Schizostacyum brachycladum, Schizostacyum sp., and Nastus sp. The kinship dendrogram shows the cluster separation between Nastus and Schizostacyum with Bambusa, Dendrocalamus, and Gigantochloa. All species identified have been used by the community, Gigantochloa atter has the most benefits than other types of bamboo. The results of this study further enrich the biodiversity of bamboo in Indonesia and strengthen the current taxonomic position of bamboo.Keywords: bamboo, bulusaraung mountain, inventory, pangkep, tompobulu villag

Petunjuk Penggunaan Alat Laboratorium Tanah dan Agroklimat dengan Fitur Stiker Quick Respone Code (Qr Code)
Full text linkAbstract. Laboratory management is an important thing where the laboratory is a facility or as a place that can be used to apply a scientific theory. Labor managers usually print documents on A4- size paper and paste them next to laboratory tools. This causes documents to be damaged quickly, can reduce aesthetics, and not suitable for small laboratory tools. The purpose of making this QR- Code sticker, the author was designed to serve laboratory users and may provide digital information and materials to laboratory users to acquire knowledge.The process of making QR-Code was conducted for 2 months, from August to September 2021.QR-Code manufacturing stages were inventory of laboratory tools, inputting documents into Google drive, testing with blackbox methods and attaching QR-Code stickers to laboratory tools. The results obtained of QR-Code stickers are fliyer and QR-Code stickers taped to several soil and agroclimat laboratory tools, it is hoped that the laboratory management system can be improved bette

Full text linkAbstract. One of the countries that has the largest mangrove forest is Indonesia, the area of mangrove forests in Indonesia reaches 3.1 million ha. Mangroves can live in tropical and subtropical climates, mangroves have so many benefits, one of which is to prevent disasters such as tsunamis and protect beaches from erosion. This research was conducted in the Pulau Dua Nature Reserve in the Banten area. This study uses a linear quadratic transect method by determining the location of the study as many as 2 station points. Data analysis was carried out quantitatively using vegetation analysis. Based on the results of the research conducted, it shows that the value of the mangrove flora diversity index is classified as low, namely H'<1. The species of mangrove flora were found such as Avicennia germinans, Avicennia marina, Avicennia officinalis, Bruguiera parviflora, and Rhizophora apiculata. The condition of the mangrove forest in the Pulau Dua Banten Nature Reserve is still relatively natural, because it is still very well preserved and the diversity of flora and fauna is still high.Keywords: mangrove, nature reserve, dua banten islan
