Abstract

The main cause of decline in banana production is fusarium wilt caused by the fungus Fusarium oxysporum f.sp.cubense (Foc). This disease is systemic, it is very dangerous because it can kill plants. Fusarium wilt disease ranks first in the list of diseases of bananas in Indonesia, fusarium wilt very difficult to control because it has not found a commercial banana cultivars resistant. Integrated Pest Management (Biological Control) using biological agents, one of which is the rhizosphere that has the ability to suppress the growth of Fusarium wilt (Fusarium oxysporumf.sp.cubense) in vitro. The purpose of this study was to determine the ability of an antagonist of the rhizosphere fungus to fungus fusarium. This research method is a rhizosphere fungal activity test against fusarium fungus. The results showed that 12 isolates the rhizosphere has the potential to inhibit the growth of fungi fusarium the percentage inhibition ie 82% of isolates A1, B2 D3 by 83% and 80%, A2 isolates the isolates that produce inhibition of the smallest amounting to 15%. Based on identification consists of rhizosphere fungi genus Trichoderma sp., Aspergillus sp., And Penicillium sp.

Abstract

Antimicrobial test was conducted on plant root extract som jawa (Talinum paniculatum, jacq. (Gaertn)). Five hundred gram simplicia of som jawa root was macerated using methanol and n-heksana, and coagulated. The screening of extract methanol and n-heksana was done to get metabolic secunder; flavonoid, alkaloid, terpenoid, and saponin. The result of phytochemistry secreening test to extract methanol to metabolic secunder was negative. Antimicrobial test result showed that the extract of som jawa root  is active againts microbes E.coli. Measurement is based on the test zone diameter of the clear zone generated, where . coli has the highest diameter of the clear zone compared with the others microbes such as Staphylococus aureus, Bacillus sp, Serratia sp, and Candida albicans. The values of the clear zone of each microbe  in order are 1,1 cm, 1 cm, 0,95cm, and 0,9 cm. These value were obtain at a concentration of 10%.

Abstract

The title of  this study is the utilization of chitosan from shellfish waste as water purifier. The purpose of the study is to utilize coagulant of shellfish waste in water treatment proes into clear water. The research variabel are the concentration of chitosan 1,3,5,7, and 9 g/l. The particle size of chitosan used in this research is 150 mesh. The time consume  8 hours for purification process. The result showed that 9 g/l chitosan shell waste is effective to water purification process. At a concentration of 9 g/l. Chitosan shellfish waste can produce clean water in complianee with health minister No. 416/MENKES/PER/IX/1990 about  water quality treatment.

Abstract

Efforts to increase the income of the PKK KWT group in Sei Rotan village are carried out by the Tridarma activity of higher education. The objectives of the service activities include increasing efforts to maximize house yard land management efforts by cultivating horticultural plants in the yard, and increasing the knowledge, understanding and skills of the community on hydrophonic plant cultivation techniques in the PKK KWT group community, Sei Rattan Village, Percut Sei Tuan District, and to improve community income which is classified as fitting to meet daily life, the implementation method applied is by conducting training and mentoring, in the training activities training is carried out: Hydrophonic Cultivation Training vertically and horizontally, Technical culture training for HEALTHY Horticulture plants through hydrophonic seeds, while in Mentoring: Guidance and Community Development who have started to apply technology, Discussion and Evaluation. the results of the activities based on the transfer of knowledge obtained a statement 60% of the community's responses strongly agree, 30% agree, increasing community knowledge after training obtained very good data 25%, good 60% and good enough 9%, and not good 0% and responses Satisfaction with PKM activities shows the data is very useful 42% and useful 52% and quite useful 2% and 0% which states not useful. The three categories of community responses show that the activities that have been carried out show that it is very important for the community to consider community knowledge and skills that are very useful for improving the quality of these farmer groups.

Abstract

The effort of Indonesian people to fulfill their protein intake in an economically accessible way is by producing and consuming oyster mushrooms, because their protein content was viable as an alternative to animal-based products. Combination of sugarcane bagasse, palm fronds (PKS), and sawdust can be used as growing medium for oyster mushrooms. The aim of this study was: (1) to analyze the change in the pH of the combination media formulation of Palm Oil Frond Waste (PKS), sugarcane bagasse, and sawdust; (2) identifying the composition of nutrients in the aforementioned agricultural waste as a growing medium for oyster mushroom. This study was composed of two steps: 1) Preparing the composition of the growing medium from agricultural waste; and 2) Analyzing nutrient composition of the growing medium of oyster mushroom. The research was conducted by using Analysis of Variance (ANOVA) with a Non-Factorial Completely Randomized Design (RAL). The combination of oyster mushroom growing medium from palm fronds, sugarcane bagasse, and sawdust has different pH levels and nutritional contents. The combination of M0 – M8 oyster mushroom growing medium has the suitable level of pH to grow the mushrooms at 6,5 – 8,0 pH. From the formulation analysis of nutrient in the combination of M0 – M8, it can be used as a reference for the nutrient content of oyster mushrooms growing medium from palm fronds and sugarcane bagasse.
