Abstract

Cycloseris vaughani is a mushroom coral from the stony coral group (Scleractinia). It is usually found free-living or colony-formed. C. vaughani can adapt to the environment through differences in body size that varies in each individual. The research aims to determine the variations in body size of C. vaughani in Kabung Island waters. Data were collected by using the belt transect method at 3 research stations. The average body size of C. vaughani individuals shown from 3 research stations was 1.1±3.7 cm, 7.1±1.3 cm and 6.3±1.2 cm. There was a significant difference in body size of the mushroom coral C. vaughani in Kabung Island waters.

Abstract

Long-term consumption or overdose of paracetamol can induce liver damage characterized by increased measure of liver malondialdehyde (MDA). The methanol extract of laban tree bark (Vitex pubescens Vahl) contains antioxidant compounds such as flavonoids, tannins, and saponins that have potential as hepatoprotectors. This study aims to determine the optimal dose of methanol extract of V. pubescens tree bark to reduce liver MDA levels of mice after being induced by toxic dose of paracetamol (TDP). This study uses a completely randomized design (CRD) and 35 male Swiss strain mice aged 2,5-3 months. The treatments given consisted of normal control (aquades); negative control (TDP 105 mg/kg weight); positive control (vitamin E 48.6 mg/kg weight) and methanol extract of V. pubescens tree bark (75 mg/kg weight; 150 mg/Kg weight; 300 mg/kg weight and 600 mg/kg weight). Based on the research results, mice that were given an extract dose of 600 mg/kg weight showed a liver MDA levels of 0.68±0.24 nmol/mL which was close to the liver MDA levels of positive control mice, which was 0.62±0.12 nmol/mL.

Abstract

The cultivation of Namalycastis rhodochorde nypa worms is still experiencing obstacles due to the high mortality rate of larvae, which can be caused by unsuitable conditions for the maintenance media. This study aims to obtain data on the conditions of environmental factors during larval rearing in the laboratory. This study observed environmental factors in 5 larval rearing treatments, namely 50, 100, 150, 200, 250 individuals/L with the size of the rearing tub (37×26×14 cm3). During rearing larvae are given 0.3×10-3 Chlorella vulgaris feed and fermented palm fronds. Data were collected every 10 days for 3 months. The parameters for observing environmental factors were water pH, water temperature, air temperature and salinity.  The results showed that the average water pH was 7.6 with a range between 7.3-7.9, an average water temperature of 25.6 °C with a range between 24-28 °C, an average air temperature of 25.9 °C with a range between 24-29 °C, and the mean salinity of 13.7 ppt with a range between 13-16 ppt. The results of the research on water quality during maintenance were relatively standard, thus supporting survival and growth of N. rhodochorde nipah worms.

Abstract

Hortaea werneckii is a fungus causes of tinea nigra. Plants that are known to have antifungal compounds are bay leaves (Syzygium polyanthum). This study was aimed to determine the best concentration of the methanol extract from bay leaves (S. polyanthum) can inhibit the growth of Hortaea werneckii (T1) in vitro. This study used a completely randomized design (CRD) with treatment levels that consisted of concentrations of 20, 25, 30, 35 and 40%, negative control (sterile distilled water) and positive control (ketoconazole 2%). The antifungal activity test was carried out using the Kirby-Bauer method. Based on the results study showed that concentration 30% is the best concentration in inhibit fungal growth Hortaea werneckii (T1).

Abstract

Weed is a plant that grow in undesirable places, especially in the location of cultivated plants. Alelochemical use as bioherbicide is one of the ways in weed control and is safe for the environment. The study was conducted to test the potential of P. jiringa fruit peel extract as bioherbicide on the germination and growth ofA .spinosus and P.conjugatum weeds. The study used a completely randomized design (RAL) with the concentration of extract (P) used consisting of 6 treatments, namely P1 = 0 (control), P2 = 0.1; P3 = 0.2; P4 = 0.3; P5 = 0.4; and P6 = 0.5 g / ml. each treatment was repeated 5 times. The results of the study showed that the concentration extract of 0.5 g / ml was an inverse concentration to inhibit the weed seeds germination ofA.spinosus and P. conjugatum. Good concentration extract to inhibit growth A. spinosus and P. conjugatum is 0.3 g / ml which results in inhibition of plant height, root length, wet weight and dry weight. Based on research conducted on fruit peel extract P. jiringa has the potential as a bioherbicide.

Abstract

Coliform bacteria can contaminate food and lead to intoxication causing symptoms of human digestive tract disorders. Food which is vulnerable to the contamination coliform bacteria is traditional food which is processed in a simple. One of Pontianak traditional food is sotong pangkong. The purpose of this research is to study the contamination of coliform bacteria on sotong pangkong sold on Jalan Merdeka, Pontianak. The research was conducted for three months from September to November 2016 it the Microbiology Laboratory of the Faculty of Mathematics and Natural Sciences, Tanjungpura University, Pontianak. This research was observative and descriptive in nature,the data were tabulated by presenting table. The result showed that the sample of sotong pangkong was contaminated by coliform bacteria in which the MPN values was above the maximum limit, except for sample which had been roasted from seller IV (<3 MPN/gram). The highest contamination sample before and after roasted were gathered from seller I and seller III where the value was >1100 MPN/gram. Meanwhile the lowest contamination on the sample before-roasted sample was recorded from seller II by 11 MPN/gram. The bacteria contamination was above the limit of bacterial contamination based on BPOM No. HK.00.06.1.52.4011 Year 2009 by <3/gram.

Abstract

Shallots (Allium cepa var. Bauji) are plants that are included in the Liliaceae family. The dominance of peatlands in West Kalimantan is one of the factors causing the low production of shallot plants. This study aims to determine the effect and concentration of duck manure tricho-compost (TKB) on the growth of shallot plants in peatlands. The research was conducted from July to October 2019. The compositions used included distilled water, bran, dolomite, sugar, potato, duck dung, urea, TSP and KCL, Trichoderma harzianum isolates, liquid Trichoderma starter, peat soil, and shallot bulbs (Allium cepa var. Bauji). The study used a completely randomized design with six treatments in the form of negative control (-); 50 g of TKB; 100 g of TKB; 200 g TKB; 400 g TKB and positive control (+). The results showed that there was a significant effect between the application of tricho-compost duck manure on growth parameters. Tricho compost treatment with 100 g of duck manure was the concentration with the best results on the growth of shallots, with a height of 28.88 cm, number of leaves 19.88, total wetness of 15.99 g, wet tuber weight 5.37 g and wet root weight 0.69 g.

Abstract

Soil Organic carbon is an organic matter contained in or on the soil surface which derives from natural carbon compounds. Soil becomes an important representation of organic carbon stock in long-term period of land ecosystem, because soil accumulates carbon larger than those in plant biomass and atmosphere. This research aims to study the correlation between soil density, soil organic carbon, and soil organic carbon stock in tembawang agroforestry area Nanga Pemubuh Sekadau Hulu West Kalimantan. The results show that soil density has a negative correlation and a real effect on soil organic carbon, and it has positive correlation and a real effect on soil organic carbon stock.

Abstract

Shorea leprosula has high economic and ecological value. Shorea leprosula population decreases due to increased illegal logging activities, especially in Gunung Palung National Park. This research aims to find out the density and spreading pattern of Shorea leprosula Miq. at Research Stasiun Cabang Panti, Gunung Palung National Park, West Kalimantan. The research was conducted from June to August 2020. The research method used is random sampling in 3 different locations, namely alluvial habitats, sandy rocks and freshwater swamps. Sampling using a squared method with a plot size of 20 x 20 m and made 10 plots on each habitat. The results showed that the density of S. leprosula is highest in freshwater swamp habitat of 170 individuals/Ha and the lowest in sandy rock habitat of 103 individuals/Ha. Spreading pattern S. leprosula is aggregate.
