Abstract

Litter decomposition ability of fungi has an important role in forest floor ecosystem. The abilities of Ganoderma sp and Trichoderma sp to decompose Acacia mangium leaf litters at laboratory scale were observed. Litters from L and F layers in the field ca. 100 g were used as substrates in plastic bags. Each fungus was inoculating onto substrates and incubates at room temperature, then observed each month during six months. Weight losses (WL) of litter, lignin and cellulose contents during decomposition were measured. Colonization of Ganoderma in litter and PDA with litter powder were also observed. The results showed that WL of litters, lignin and cellulose by Ganoderma were low. WL of L and F litters were 3.99% and 4.57% respectively, while WL of  L and F lignin were 8.17% and 7.11% respectively, and WL of  L and F cellulose were 3.63% and F 2.59% respectively. WL of L and F litters by Trichoderma were 3.20% and 3.20% respectively, while WL of  L and F lignin were 3.83% and 3.85% respectively, and WL of  L and F cellulose were 2.43% and 3.17% respectively. The growth of Ganoderma was better at PDAS than that at PDA; therefore L litter layer was suitable for growing Ganoderma.

Abstract

Tomato (Lycopersicon esculentum L.) is an important horticultural crops but very susceptive in their growth. It is known that the plant growth can be influenced by microorganisms, such as symbiosis between plants and endophytic fungi. Endophytic fungi are fungi that live in the tissues of living plants and will not cause any negative effects on its host. This study aims to determine the growth of tomato plants affected by endophytic fungi isolated from Mangrove root collected from Pulau Dua Sanctuary Serang Banten, both in vitro and in vivo. There were five isolates endophytic fungi of mangrove root (CEM), collection of biology education laboratory UNTIRTA, which is used in this study: CEM 2, CEM 3, CEM 4, CEM 7, and CEM 9. The research conducted by inoculating tomato seedlings on MS medium that has been grown by endophytic fungi for in vitro growth, while the in vivo growth carried out by inoculating tomato seedlings on zeolite medium with corn as a fungi carrier. Morphological observation and plant growth parameters measured after 5 weeks incubation. The result showed that CEM 9 is the potential endophytic fungi from roots of Mangrove Pulau Dua Sanctuary Serang to increase tomato growth.

Abstract

The aim of this research is to measure biodiversity of freshwater prawns in Danau Teluk Jambi City. This is a quantitative descriptive research, the samples were taken purposively from three stations. The collected data were analyzed to obtain biodiversity index and dominance index.  Some nvironmental parameters were also measure including temperature, water depth, pH, DO (Dissolved Oxygen), COD (Chemical Oxygen Demand), and BOD (Biochemical Oxygen Demand). The research found 170 individual freshwater prawns belonging to 3 species: Macrobrachium rosenbergi, Macrobrachium lanchesteri, and Macrobrachium sintangense. Biodiversity index (H’) in stations I, II, and III were 0.85, 1.0, and 0.74 respectively and dominance index were 0.51, 0.39, and 0.51 respecytively. The value of physical and chemical water factors of the the three station were: water depth 0.6-2.6 m, temperature 28-31°C, pH 6.49-6.72, BOD 16-20 mg/l, COD 36-43 mg/l, and DO 6.61-6.63mg/l. The result indicated that biodiversity of freshwater prawns in Danau Teluk Jambi City was relatively low  and there was species that dominated the water (Macrobrachium lanchesteri).

Abstract

This study aims to observe the response of nyamplung seedling to various of flooding levels, using a randomized block design with a single factor of five inundation treatments (control, 0 cm or equal the solil surface, 4 cm, 8 cm, 12 cm). Flooding treatment was carried out for 30 days. The observed parameters were growth rate, morphological adaptation, and injury index. Data were analyzed using ANOVA and Duncan Multi Range Taste (DMRT) in the level of 5%.  The results showed that flooding treatment reduce the growth of nyamplung seedling (fresh weight, height, stem diameter, number of leaves, leaf area, and fesh root weight). Seedling of nyamplung able to survive on equal ground flooding level and 4 cm above the soil surface, classified as moderately tolerant plants. Seedlings were not able to survive in the flooding level of 8 cm and 12 cm, classified as sensitive plants. Morphological adaptations such as lenticels formed by 20% on equal ground surface flooding level and 60%  on the flooding level of 4 cm.

Abstract

Banana (Musa sp.) is the most widely consumed fruits since the children age up to the elderly. This is because bananas have quite complete nutrient content such as carbohydrates, proteins, vitamins and minerals, making it beneficial for the human body. People normally only consume and discard any banana skin. Therefore; it needs solutions to deal with the banana peel waste. Banana peels contain high enough nutrients that are carbohydrate 18.5%, phosphorus 28 mg, water 72 g, and some other chemical substances. The high nutrient content on the banana peel is potential to be used as food, one of which is in the form of nata. Nata is a product of microbial fermentation using Acetobacter xylinum. Nata can be made from coconut water waste, liquid waste or waste bark out pineapple and banana peel waste (Nata de Banana Skin). This study aimed to determine the effect of various types of banana peels using A. xylinum on the quality of nata de banana skin. The results showed that different types of banana peel affect the quality of Nata de Banana Skin, both on its flavor and its yield of Nata de Banana Skin. The pisang raja skins give the most optimal results for nata thickness and also perform the best organoleptic values.

Abstract

The purpose of this experiment was to identified the population distribution of Azotobacter sp and organic matter on variety slope classification at experimental field, PPTK Gambung, West Java. The methode that used was exploration method. PPTK Gambung’s tea plantation has three class of slope, they are slope of <8% (flat-rather slope slighty), 8-15% (slope slighty), and 16-25% (rather steep). Total 14 composite soil sample taken from each of the class to analyze total population of Azotobacter sp, average of organic matter soil content, and water content average. Sample was taken based on sample point in Land Unit Map (SPL). Slopes <8% (flat-rather slope slighty) have total population of Azotobacter sp around 7,14x107 cfu/gram soil, water content 5,97%, and organic matter 10,68%. Slopes 8-15% (slope slighty) have total population of Azotobacter sp around 10,38x107 cfu/gram soil, water content 6,47%, and organic matter 10,91%. And slopes 16-25% (rather steep) have total population of Azotobacter sp around 11,75x107 cfu/gram soil, water content 6,34%, and organic matter 10,65%.
