Abstract

Streptomyces merupakan bakteri dari kelompok Actinomycetes. Genus ini diketahui dapat memproduksi berbagai senyawa aktif diantaranya antibiotik, antiviral, dan enzim. Enzim yang dapat ditemukan pada bakteri dan jamur yaitu salah satunya enzim kitinase. Enzim kitinase yang diproduksi oleh bakteri lebih baik dibandingkan kitinase dari sumber lain karena dengan waktu yang relatif singkat dapat melakukan proses perkembangbiakan. Bakteri kitinolitik merupakan agen pengendalian hayati terhadap jamur patogen maupun serangga hama yang sangat potensial karena aktivitas kitinase yang dimiliki. Penelitian ini bertujuan untuk mengisolasi, mengetahui karakteristik Streptomyces spp. dari lumpur selokan dan uji aktivitas enzim kitinase. Aktivitas enzim kitinase diketahui melalui zona bening yang terbentuk pada media uji. Hasil penelitian diperoleh lima spesies Streptomyces spp. dari sampel lumpur selokan yang diisolasi dengan karakteristik yang berbeda-beda. Hasil penelitian juga menunjukkan bahwa dari lima spesies Streptomyces spp., dua spesies yaitu Streptomyces sp.3 dan Streptomyces sp.5 mampu memproduksi enzim kitinase, sementara tiga spesies Streptomyces lainnya tidak memproduksi enzim kitinase. Streptomyces sp.3 memproduksi enzim kitinase dengan terbentuknya zona bening sebesar 1,85±0,07 cm dan pada Streptomyces sp.5 terbentuk zona bening sebesar 0,65 ±0,14 cm . Berdasarkan data tersebut Streptomyces sp.3 dan Streptomyces sp.5 memiliki potensi sebagai bakteri kitinolitik yang memiliki manfaat sebagai agen pengendalian hayati.

Abstract

This study aims to determine the diversity of insects and plants used as a habitat in unburned and previously burned peat land forests in Palangkaraya, Central Kalimantan. Insects were collected by beating the branches of plants, aerial sweeping, pitfall traps and light traps. Plants were identified in situ or plant samples were collected and identified later in the Lab. The diversity of insects were compared between unburned and previously burned peat forests by analyzing its index diversity (H’) and index of similarity (IS). In total, the insects collected from unburned peat forest were 551 individual, belongs to 12 order and 51 families, and 431 individual insects were collected from previously burned peat forest which belongs to 10 order and 38 families. The family of insects that most frequently found at both areas was Formicidae (Hymenoptera). The insects diversity of both forests were still high, that is H' = 3,45 of unburned peat forest and H '= 3,11 of previously burned peat forest, with the similarity index IS > 50% of both peat forests. The number of plant species found was higher in unburned peat forest (38 species) than in previously burned peat forest (9 species). The previously burned forest was dominated by Acacia plants, while in unburned peat forest the plants seem to evenly spread.

Abstract

Taman Nasional Way Kambas Lampung (TNWK) berlokasi di Ujung Selatan Pulau Sumatera dimana Gajah Sumatera dikonservasi. Gajah Sumatera (Elephas maximus sumatranus) merupakan satwa yang dilindungi dan terdaftar dalam red list book International Union for Conservation of Nature (IUCN), dengan status terancam punah. Penelitian ini bertujuan untuk mengetahui perilaku harian anak Gajah Sumatera (Elephas maximus sumatranus) di Pusat Konservasi Gajah tersebut. Pengambilan dan pengumpulan data perilaku harian dilakukan dengan metode “fokal animal scan sampling” yaitu masing-masing individu hewan di luar kandang diikuti selama satu hari dan data diambil dengan interval 5 menit. Pengambilan data dilakukan pada pagi hingga malam hari pukul 08:00 - 21:20 WIB. Penelitian dilakukan dari tanggal 25 Januari 2016 hingga 3 Maret 2016. Dari hasil pengamatan didapatkan bahwa sebagian besar waktu anak Gajah Sumatera digunakan untuk makan, mencari makan dan bergerak, dan hanya sebagian kecil waktunya untuk beristirahat, bermain, minum, mandi, buang air kecil, dan buang air besar. Misalnya, 34,2% waktu harian anak gajah digunakan untuk makan, 21,8% untuk bergerak dan hanya 4,8% untuk beristirahat. Jenis makanan yang paling sering ditemukan dimakan oleh gajah adalah rumput ilalang (Imperata cylindrica).

Abstract

This research was aimed to find out the genetic structures of three generations of Balinese population, in order to determine the best loci used for paternity testing among this population, and observed the mutation rate of these loci. The DNA samples were taken from the epithelium cell of 25 families which were collected from the children, father, mother, grandfather and grandmother of the children, from both mother and father sides (family with three generations). The DNA was extracted in Phenol-Chloroform method with modifications. DNA amplification was conducted in PCR method using pairs of primer 5, namely: FGA, D18S51, D2S1338, TPOX, and D16S539, and its products were electrophoresed and visualized in 10% of PAGE, stained in silver nitrate. The genetic structures of the three family generations showed 30 variants with different frequencies in each locus. The highest heterozygosity value was detected in FGA (8 alleles), then followed by D18S51 (7 alleles), TPOX (6 alleles), D16S539 (5 alleles), and the lowest was in D2S1338 (4 alleles). The highest value of heterozigosity and Power of Discrimination were found in FGA, followed by TPOX, D18S51, D2S1338, and the lowest was in D16S539. Therefore, it can be concluded that out of five loci tested, 4 of them can be recommended to be used for paternity testing of Balinese population, except D16S539.

Abstract

Pollination is the most important live processes for plant especially for seedling plant. Some previous research results show that insects play an important role in helping the pollination process both in wild plants and in productive plants. The eggplant (Solanum melongena L.) is one of the important agricultural commodities. However, the eggplant production in the local farming system today often experiences obstacles when its production is not in sufficient quantities. The potential of Apis cerana L. as a pollinator is a chance solve the productions problems. The purpose of this study was to determine the role of honey bees (Apis cerana L.) in increasing yield of eggplant (Solanum melongena L.).This study obtained the eggplant productivity data. All data was collected and analyzed with SPSS 17 statistical program. Before analysis, all data normality were tested and it was analyzed by One-way ANOVA and when significant differences were found, analysis was continued with the Tuckey Test to find out the difference within treatment with a significance value ???? <0.05 .The results of this study note that bees have a certain amount of time to carry out their activities and the addition of bees colony to the experimental field produced two times more of yield compared with the other groups that were not treated with he colony.

Abstract

Sungai Telagawaja adalah salah satu sungai alami dengan panorama alam dan persawahan yang menarik, sehingga beberapa bagian lahan mulai beralih fungsi menjadi kawasan penunjang pariwisata maupun pemukiman. Akibat dari alih fungsi lahan ini menyebabkan penurunan kualitas air dari Sungai Telagawaja. Penurunan kualitas air ini menyebabkan menurunya daya guna, hasil guna, produktivitas, daya dukung dan daya tampung dari Sungai Telagawaja. Selain dari alih fungi lahan, kegiatan pertanian yang menggunkan pupuk pada lahan pertanian secara berlebihan, serta pemeliharaan hewan ternak disekitar sungai yang membuang limbah kotorannya langsung tanpa pengolahan limbah, memperburuk kondisi air Sungai Telagawaja. Sehingga diperlukan kajian mengenai kondisi Sungai Telagawaja terkini. Penelitian ini dilaksanakan pada bulan Febuari 2021. Lokasi pengambilan data bertempat di perairan Sungai Telagawaja dengan 3 tiitk pengambilan sampel. Paramater yang diamati meliputi suhu, TSS, TDS, ph, DO, COD, BOD, dan fecal coli. Hasil parameter yang didapat dianalisis dengan metode STORET untuk baku mutu kelas 1 untuk peruntukan air minum berdasarkan Peraturan Peraturan Gubernur Bali Nomor 16 Tahun 2016 Tentang Standar Baku Mutu Lingkungan (Baku Mutu Kualitas Air Berdasarkan Kelas). Hasil yang didapatkan di ketiga titik pengambilan sampel Sungai Telagawaja termasuk pada kondisi buruk. Nilai untuk masing bagian sungai yaitu pada bagian hulu Sungai Telagawaja dengan skor -40, pada bagian tengah Sungai Telagawaja dengan skor -38, dan pada bagian hilir Sungai Telagawaja dengan skor -40. Ketiga skor yang didapat melebih nilai skor 31 yang artinya kondisi air di Sungai Telagawaja dalam kondisi buruk atau dalam kondisi tercemar berat.
