IDENTIFIKASI CENDAWAN YANG BERPOTENSI MENYEBABKAN PENYAKIT BUSUK KUNING PADA BATANG TANAMAN BUAH NAGA

The attack of pathogenic fungi on dragon fruit plants in Penyak Village causes severe damage and shows symptoms of yellow rot on the trunk of dragon fruit. The research method used is exploration and identification. This study aims to explore fungi that have the potential to cause yellow rot based on the symptoms of yellow rot on the stems of dragon fruit plants in Penyak Village, Koba District, Central Bangka Regency. The results of 16 stem samples obtained 64 isolates and based on macroscopic and microscopic identification results of each isolate obtained seven genera namely Acremonium, Alternaria, Aspergillus, Cladosporium, Geotrichum, Fusarium, and Pestalotiopsis. The most common pathogenic fungi at mild symptoms are Pestalotiopsis, Alternaria, and Fusarium. Environmental factors (abiotic) such as soil moisture and air humidity that are high enough to affect the genus present, especially Fusarium.

PERTUMBUHAN DAN KADAR KLOROFIL DAUN Acacia mangium PADA LAHAN BEKAS TAMBANG TIMAH DI PULAU BANGKA

Tin-mined land has sandy characteristics (more than 95%), is very porous, low KTK, acidic pH and nutrient poor. Revegetation programs have been carried out to improve soil fertility using local and exotic species (Acacia mangium). Rapid growth, tolerance to various environmental conditions and high economic value are the reasons for choosing A. mangium as a revegetation plant. This study aims to analyze the growth and chlorophyll content of A. mangium leaves which grow in two locations of tin-mined land (Tanjung Ratu Village and Rebo Village). The results showed that A. mangium which was grown on a younger tin mined land (in Tanjung Ratu Village) showed an increase in root dry weight, root length, number of root nodules, and decreased leaf chlorophyll levels. On older tin mined land (in Rebo Village), root dry weight, root length, and number of root nodules were lower, but chlorophyll content increased. The characters affected can be used to determine the ability of tolerance and adaptation of A. mangium in tin mined land.

KEANEKARAMAGAN JAMUR MAKROSKOPIK DI KAWASAN TAMAN WISATA ALAM PERMISAN, KABUPATEN BANGKA SELATAN

Fungus is one of the main biotics component in ecosystem, included forest. The played a significant role in organic material decomposition.

STUDI ETNOBOTANI TANAMAN PANGAN SUKU JERIENG DI KECAMATAN SIMPANG TERITIP, KABUPATEN BANGKA BARAT

Plant has many benefit in life, one of example is etnic’s edible food. Jerieng etnic is origin etnic living in the west Bangka district, Bangka Beltung province. Food is everything that grows, lives, has stem, roots, and leaves are eaten directly or need to be processed. The purpose of this research is to record the diversity of food crops (types of edible plant based food, number of species, parts used, processing. This research was conducted from January to November 2018. The research in 13 villages in Simpang Teritip District, West Bangka Regency. Locations include Pelangas Village, Simpang Gong, Air Nyatoh, Pangek, Peradong, Kundi, Air Menduyung, Rambat, Simpang Tiga, Terak Hill, Ibul, Berang, and Mayang. This research aims to do interview and direct observation with the key informant using purposive sampling method. The result of this research found that there are 79 species from 34 families of edible plant-based food in Jerieng etnic. Solanaceae is the most numerous family found including 9 species. The most often used plant part is fruit (39%), meanwhile the less often used plant part is bud (1%). Edible plant based food by Jerieng etnic is divided into two groups, those are processed food and unprocessed food. Example of unprocessed food is local salad (known as “lalapan”) and the processed food such as lempah darat and lempah kuning.

PENGARUH PERBEDAAN JENIS MEDIA TANAM TERHADAP PERTUMBUHAN SETEK Hoya coronaria BERBUNGA KUNING DARI KAWASAN HUTAN KERANGAS AIR ANYIR, BANGKA

The research to study the influence of the growing media on the growth of Hoya coronaria yellow flowered from Air Anyir heath forest, Bangka was carried out to know the best growing media. It is a first step to cultivate H. coronaria from the wild of the area. This research was done on September 2015 until January 2016 at trial house on Gabek II, Pangkalpinang. Growing media chemical analysis was done at Biology and MIPA laboratorium, Faculty of Agriculture, Fishery and Biology, Bangka Belitung University. This research used completely randomized factorial pattern using a single factor with 7 levels. The experiment was used seven different growing media podsol, red yellow podsolic (ultisol), moss, coco peat, podsol + ultisol, podsol + coco peat and podsol + moss. This research applied 3 replications with 3 Hoya cutting each of replication. Observed parameters were the establishment of cuttings (life cutting persentation), cutting growth persentation, shoot length, shoot diameter, roots total number, root length, leaves total numberand leaf wide. The result showed all growth parameters did not significantly different by the influence of different growing media. The best root growth is on PPMK (podsol+ultisol), while the best shoot growth and the best leaves growth are on the moss.

FAG Salmonella ASAL LIMBAH PASAR IKAN DAN AIR SUNGAI DI SEKITAR KAMPUS UNIVERSITAS BANGKA BELITUNG

Seven Salmonella lytic phages found in water sample of river near UBB campus building. Phages were characterized by plaque morphology (plaque diameter size and shape) and phage host range. Phages formed plaques with diameter size ranges from 1.06 mm to 4.90 mm, and form shape such as small dot, circle, elongated, or irregular. Factors effect plaque forming by phages are phage titer number and incubation time. All phage isolates have broad host range include Gram negative and positive.

PEMANFAATAN TANAMAN OBAT OLEH SUKU JERIENG DI KABUPATEN BANGKA BARAT

Indonesia has been know as own high diversity of flora and fauna. In addition, Indonesia has been know high diversity of ethnics which has various distinctive traditions, including local knowledge.
