Abstract

Abstract. 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 village

Abstract

Abstract. 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 island

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh dan konsentrasi optimum pemberian tepung cangkang dan kepala udang vaname (Litopenaeus vannamei) terhadap penurunan hiperkolesterolemia pada mencit (Mus musculus). Penelitian ini terdiri dari 4 kelompok perlakuan yaitu P0 (pakan hiperkolesterol dicampur tepung cangkang dan kepala udang sebesar 0%), P1 (pakan hiperkolesterol dicampur tepung cangkang dan kepala udang sebesar 5%), P2 (pakan hiperkolesterol dicampur tepung cangkang dan kepala udang sebesar 7%), dan P3 (pakan hiperkolesterol dicampur tepung cangkang dan kepala udang sebesar 9%). Metode penelitian terdiri dari beberapa tahap yaitu pembuatan pakan hiperkolesterol, pembuatan tepung cangkang dan kepala udang, pembuatan pakan perlakuan hewan uji, perlakuan hewan uji, serta pengukuran kadar kolesterol. Analisis data menggunakan uji One Way ANOVA dan uji lanjut Duncan. Hasil penelitian menunjukkan nilai rata-rata kadar kolesterol awal kelompok perlakuan P3 berbeda sangat nyata terhadap kelompok perlakuan P0, P1, dan P2. Nilai rata-rata kadar kolesterol akhir kelompok perlakuan P2 berbeda sangat nyata terhadap P0 dan berbeda nyata terhadap P1 dan P3. Hasil penelitian menunjukkan bahwa konsentrasi tepung cangkang dan kepala udang paling optimum ialah 7% (P2) yang mampu menurunkan hiperkolesterolemia pada mencit (Mus musculus) sebesar 0.29%.

Abstract

Nata is a biotechnology product that utilizes Acetobacter xylinum in the fermentation process. Making nata requires materials that contain carbohydrates and nitrogen. The raw materials for making nata generally use coconut water, fruit extracts, and sago waste. Sago liquid waste can be used because it contains starch as a carbon source to form polysaccharides. In addition to starch content, making nata also requires nitrogen supply. Increased nitrogen supply can increase the amount of polysaccharide formed. This study aims to determine the effect of giving different types of nitrogen sources, namely urea, ZA, and touge extract and control without the addition of nitrogen on the characteristics of nata de sago. This study used the RAL method (Completely Randomized Design) which consisted of 4 treatments and 3 repetitions. The results showed that the addition of 1.5 g of urea produced the best nata characteristics based on thickness, color, and aroma, but based on texture characteristics the best value was obtained in the bean sprout extract treatment. The results of this study become an alternative to the use of sago leachate as a raw material for making nata and an alternative to the use of natural nitrogen sources from bean sprout extract which is organic and has no residue in the final product of nata.Key words: Nata de sago, nitrogen, organoleptic

Meningkatnya kejadian resistensi bakteri terhadap antibiotik, mendorong pemanfaatan obat herbal dalam mengobati penyakit infeksi. Daun Acacia auriculiformis diketahui memiliki senyawa metabolit yang dapat menghambat pertumbuhan bakteri Gram positif dan negatif. Penelitian ini bertujuan untuk mengetahui aktivitas antibakteri ekstrak daun A. auriculiformis terhadap pertumbuhan bakteri Bacilus sp., Staphylococcus aureus dan Escherichia coli secara in vitro. Penelitian ini dilakukan dengan mengekstrak daun A. auriculiformis menggunakan pelarut etanol. Uji daya hambat ekstrak daun A. auriculiformis dilakukan dengan metode difusi sumur. Adanya aktivitas antibakteri ditunjukkan dengan adanya zona bening di sekitar sumur. Hasil penelitian menunjukkan bahwa ekstrak daun A. auriculiformis memiliki kemampuan menghambat pertumbuhan bakteri Bacillus sp. dan Staphylococcus aureus dengan kategori daya hambat tergolong kuat. Ekstrak daun A. auriculiformis tidak mampu menghambat pertumbuhan bakteri Escherichia coli. Uji golongan senyawa dengan metode skrining fitokimia menunjukkan bahwa daun akasia mengandung senyawa flavonoid dan tanin yang bersifat antibakteri.

Abstract

Biosurfactants 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.
