Abstract

Fruit flies (Drosophila melanogaster) generally have four phases in their life cycle, namely eggs, larvae, pupae and imago. In general, Drosophila melanogaster experiences a life cycle of 8-11 days at optimal temperatures. At lower temperatures the time required to complete its life cycle is relatively longer and slower which is around 18-20 days. Whereas at higher temperatures adult flies that grow will be sterile. The development period of Drosophila melanogaster in its life cycle is influenced by several factors, namely ambient temperature, food availability, level of maintenance density and light intensity. This study aims to determine the effect of temperature on the life cycle of fruit flies (Drosophila melanogaster). The study will be analyzed using quantitative analysis using randomized block design (RBD) with six temperature difference treatments for each treatment and repeated 4 times so that there are 24 experiments. The results showed the development in the Drosophila melanogaster cycle starting from Egg - Larva (Instar I) - Larva (Instar II) - Larva (Instar III) - Pre Pupa - Pupa - Imago. The life cycle of Drosophila melanogaster has an average of 42.08 hours or 1.75 days up to 79.96 hours or 3.33 days in each treatment. And obtained a fast time during the life cycle of Drosophila melanogaster at a temperature of 30°C is 10.47 days and the longest at a temperature of 18°C is 18.35 days.

Abstract

The native bacteria have a wide life habitat and have an important role as agents in the bioremediation process of waste. Batik as one of the products of Indonesian character, has become a contributor of liquid waste that can reduce water quality. Besides being rich in dyes, batik waste is also rich in fat content. The fat content in batik waste comes from the processing (coating the fabric with a layer of wax) and washing is done repeatedly. Fat has properties that are not soluble in water and is an organic material, which if high concentrations can reduce water quality. This study aims to isolate, identify, and measure the ability of indigenous bacteria to reduce fat content in liquid waste in vitro. The method used is experimental research. Isolation and culture using Busnall Hass media enriched with 1% olive oil, then proceed with a series of biochemical tests for the purpose of characterizing indigenous bacterial isolates. The results showed that Bacillus subtilis and Pseudomonas fluorescens have the potential to reduce the fat content of batik liquid waste.

Abstract

The growth of mushroom requires nutrients such as cellulose, hemicellulose and lignin which can be obtained from rice straw. However, the availability of rice straw at certain times is difficult to obtain. Dried banana leaves and corn husk have the potential to be used as alternative growing media because they contain cellulose, hemicellulose and lignin for the growth of mushrooms. This research was conducted to determine the productivity of straw mushrooms on a mixture of dried banana leaf media and corn husk planted in a basked. The method used RAL (Completely Randomized Design) which consisted of one factor, namely a mixture of 500gr, 375gr, 250gr, 125gr, and 0gr corn shells with Ogr dried banana leaves, 125gr, 250gr, 375gr, and 500gr. Data were tested by one-way Anova analysis. The result showed that there was no effect of the mixture of dried banana leaves and corn husk on the productivity of straw mushrroms. Mushroom can grow on all treatments.

Abstract

Above Ground Biomass (AGB) forest ecosystem is one of the fundamental parameters to describe each of its functions. Carbon in the forest ecosystem accumulates through absorption of CO2 in the atmosphere and is assimilated into biomass. The study of forest vegetation biomass is important for determining carbon storage in dominant tree components and calculating carbon cycles at regional and global levels. Kalibiru Forest carbon storage information is not yet available, so it is necessary to calculate carbon potential. This study aims to calculate aboveground biomass and estimate carbon stocks in the Kalibiru Forest. The study was conducted in Kalibiru Hamlet, Hargowilis Village, Kokap District, Kulon Progo Regency. The research conducted the indirect method (non-destructed) to calculate biomass and carbon by using the allometric equation. Base on the calculation, Kalibiru Forest has 5.086,52 tons of biomass or 175,40 tons per hectare in average. The potential for carbon storage in the Kalibiru Forest is 2.543,26 tons of carbon or 87,7 tons per hectare in average. This figure means that preserving 1 hectare of Kalibiru Forest can avoid the impact of atmospheric damage due to the greenhouse gas effect as many as 87,70 tons per year. Results of this study provide an insight for the surrounding community about the importance of the existence of the Kalibiru Forest as an absorber of CO2 gas in the atmosphere. As another benefit, it provides motivation for the surrounding community to continue in preserving the forest.

Abstract

High plastic demand has the potential to cause problems because plastic is a synthetic polymer made from petroleum that is difficult to decipher. Therefore, saving the current development of biodegradable plastics that can be decomposed by microorganisms naturally. Cassava rubber tubers are rarely used because they contain HCN toxin but have a carbohydrate content of 98.4674%, so it has the potential as a bio-plastic material. The purpose of this study was to determine the Bioplastic Quality of Cassava Rubber with the addition of a combination of Plasticizer Glycerol with Sorbitol and Chitosan. The study was conducted in the lab. Biology FKIP UMS, research methods used are experimental research methods. The study design used was completely randomized design with 2 treatment factors, namely: treatment factor 1 volume of glycerol (G), G 1 = 3ml; G 2 = 5ml; G 3 = 7ml. Treatment factors are 2 types of Plasticizer (P), P1 = Sorbitol and; P2 = Chitosan. The analysis used is descriptive qualitative used to test tensile resistance, elongation at break. Based on the results of the study showed the strongest spacer resistance, G1P1 which is 17.20N / mm², and the highest breaking length, G3P1 which is 24.00%. with sorbitol and chitosan.

Abstract

The development of teak clones (Tectona grandis L.f.) is currently being done by industry and farmers to increase productivity. The use of superior teak clones will determine the success of planting; therefore, the superior clones need to be developed. Knowledge of variations in growth and fruiting in the seed orchard of teak clones is important to determine the reproductive capacity of a plant. Therefore, study on variations in the growth and fruiting of teak clones was undertaken. The study was conducted at 11 years old of teak clones, located in Alas Ketu Wonogiri, Central Java. The teak plants measured were planted with a spacing of 2 x 6 m, using a randomized block design, with 100 clones; 3 ramet per clone and consists of 5 blocks as replications. The clones originated from Gunung Kidul, Madiun, Cepu, Wonogiri, Randublatung, Rembang, Muna, Matakidi, Kendari, Buton, and Thailand. All individual tress in the plots were examine for collecting data. Parameters were measured including height of trees, diameter breast height, flower and fruit production. The results showed that height and diameter growth varied significantly between clones, as well as between replications; while flower and fruit production did not show significant differences between clones and between replications. When the clones grouped in height class and diameter class, it showed that the production of flowers and fruits of teak clones were differs significantly. Moreover, the reproductive success of this teak clone seed orchard was very low at 2.15%, suggested due to very little rainfall during the flowering season which causes many flowers to fall out.
