Abstract

The process of sugar cane into sugar which is carried out in the sugar mill produces bagasse obtained from the milling process around 32% of the total cane processed. Sugarcane production in Indonesia in 2007 amounted to 21 million tons, the potential of bagasse produced about 6 million tons of bagasse per year. Up untill now almost every cane sugar mills uses bagasse as boiler fuel, animal feed mixes and the rest are burned or thrown away. One of alternative solid waste management is to turn solid waste into compost.The purpose of this research is to understand the effect of bagasse fertilizer on growth and progress of peanut plants (Arachis hypogaea L.). Bagasse fertilizer made using cow dung as bioactivator. Bagasse obtained from several places in Semarang mashed with finely enough size. Then, with a ratio of cow dung and bagasse 1: 3. Placed in a container then mix and sealed until there is no incoming air. Every 4 or 5 days in 4 weeks is being inverted. After 4 weeks it will get bagasse fertilizer with characteristic brown color, odorless and slightly moist. This research uses three treatments there are peanuts with mixed bagasse fertilizer on the soil medium, compost on the soil medium, and without fertilizer then measured the progress for 14 days. After 14 days, so it obtained an average of plants height and number of leaves. Respectively, are 2.10; 1.38; 2.24 while the number of leaves are 2.55; 2.66; 3.22

Abstract

Increased phenotypic diversity is needed to increase the economic value of Aglaonema. However, information on increasing phenotypic diversity of Aglaonema using gamma-ray irradiation has not been widely known. This study aimed to investigate the effect of gamma ray irradiation treatment to the performances of two varieties of Aglaonema. This research was arranged factorially using randomized group design (RKLT) of two factors consisting of 8 combinations of treatments that are 4 level of irradiation dose and 2 Aglaonema varieties. The results showed that the induction of gamma ray irradiation decreased the % viable of the plants, the number of leaves, leaf length, leaf width, and the % green color as well as increased the % blue on the leaves of Aglaonema Butterfly and Aglaonema Siam Aurora. The interaction between dose of irradiation and aglaonema varieties was obtained in the % red of leaf color. Both of Aglaonema varieties had a high radiosensitivity with LD50 values ranged of 16.70 - 17.14 Gy

Abstract

Insecticidal properties of fractioned extracts from Pangium edule Reinw seed and Annona muricata seed against Plutella xylostella larvae were investigated in the laboratory. The study was initiated to investigate the possibility of using botanical pesticides to control P.xylostella, a serious cosmopolitan pest of crucifer plants. The study aims to determine the most effective concentration and the most active extract;  to evaluate the different extract concentrations on the treated larvae; and to characterize the phytochemical contents of the most effective extracts fraction. The study was an experiment initiated by test of phytochemical screening test in order to discover the presence of secondary metabolites in the extracts. It was followed by the test of mortality of the diamondback moth larvae. Furthermore, the extracts hexane fraction and etanol fraction, were conducted with completely randomized design; The LC50 values were determined following probit analysis, the data were treated in the software programme IBM Statistic SPSS 20. Results showed that n-hexane fraction is the most effective againts larvae (LC50-48h = 12,71 mg/L) from P.edule seed extract, (LC50-48h = 50,81 mg/L) from A.muricata seed extract. Larva mortality was highest using 1000 ppm n-hexane fraction (96,6%) derived from P.edule seed extract, (93,3%) derived from A.muricata seed extract. The ethanol fraction tested positive for alkaloid, saponins, flavonoids, terpenoids, phenol and tannins. N-hexane fraction of P.edule seed extract, and A.muricata seed extract are an effective botanical insecticides exhibiting larvicidal and antifeedant properties against P.xylostella thus it can be alternative to synthethic insecticides.

Abstract

Coastal communities play an important role in marine and fisheries development, as well as forming a culture in coastal areas. The socio-economic life of coastal communities in Kolakaasi Sub-District of Kolaka District is far from prosperous as the data obtained from Badan Pusat Statistik  of Kolaka (2015), the number of poor population in Kolaka reached 27,210 with the percentage of 14.68%. Partners in this IbM activity are teenagers who drop out of school environments and groups of housewives living in coastal areas. The problem of partners in the activities of IbM is the number of teenagers dropping out of school in the partner environment due to the low level of welfare of coastal communities so that the average level of the highest education is junior high school where the young women have to help the family economy by working as laborers in traditional markets of Kolaka or only help parents at home while the men work at sea. Fishing is highly dependence to the nature, so that if the weather is bad then the fishermen cannot gain  income. IbM-Integrated Farm by making "POC-FISH" is the manufacture of liquid organic fertilizer that combines agricultural activities with fisheries. POC-FISH is mad of small fish, commonly called lure fish (teri) by Kolaka community. This type of fish is abundant in Kolaka and sold cheaply (R.p 5,000/Kg). The purpose of this IbM activity was the empowerment of coastal communities through the transfer of science and technology by utilizing local potentials so that the partners involved can begin to be productive and economically independent by conducting business on a household scale. The method of making POC - FISH will be carried out simply so that technology transfer can be easily understood by partners. The process of transfer of science and technology was carried out with the pattern of 1) the education of the partner group on the importance of technology adoption by utilizing the potential and local wisdom that will be able to produce a product with higher economic/selling value 2) POC-FISH making training 3) mentoring partner group in marketing 4) monitoring and evaluation. The outgoing plan of this IbM activity is the publication of the ISSN national journal published in 2017 and POC-FISH Products

Abstract

Whey waste contains organic materials, particularly high complex proteins and amino acids in the form of suspended and dissolved solids, however the utilization of whey as a organic liquid fertilizer still has a less attention. Thus the Utilization of the whey waste through anaerobic process to be used as a organic liquid fertilizer is the purpose of the research. This research was conducted using factorial design with completely randomized design (CRD) which consists of two factors: the yeast concentration (without yeast; 0.25 and 0.50 g/500 ml of whey waste) and the fermentation time (0, 3, and 5 days). The variables measured were the content of organic C, C/N Ratio, and Total N, P2O5 and K2O contents. The results showed that the fermented whey waste on the different fermentation time and yeast concentration had increased the organic C and C/N ratio, but decreased P2O5 and K2O contents. The utilization of whey combined with solid or other liquid wastes gave a chance to produce a quality organic liquid fertilizer

Abstract

Kolaka is known as "Kolaka Cocoa City". Cocoa is the main commodity of Kolaka Regency. Kolaka is one of the cities in Southeast Sulawesi. Southeast Sulawesi is one of the provisions in Sulawesi which is the center of cocoa production after South Sulawesi with total area of 260,458 ha and with production 142,156 tons (Ditjenbun, 2012). Cocoa production centers in southeast sulawesi are located in Latambaga and Samaturu Sub-districts. Partners in the IbM program are cocoa farmers of Induha Urban Village, Latambaga Sub-district and cocoa farmer in Samaturu Sub-district. Various cooperation programs have been conducted to improve the quality of cocoa commodities in Kolaka District. In its development, classical problems remain faced by partner farmers both in terms of production and business management. In terms of production, pre-harvest problems faced by farmers are cocoa pests and diseases, which cause the farmers’ dependence on pesticides and chemical fungicides as well as the age of plants, therefore, it is important to reduce the use of pesticides and chemical fungicides because in the long term it can have adverse impact on environmental sustainability and health. The problem of post-harvest for partner farmers is a low quality of cocoa production. Most cocoa farmers process cocoa fruits to be dried beans in a rough way so that ± 90% of the cocoa beans produced by farmers have a low quality with the main characteristic is not fermented. The problem faced by farmers  in the marketing chain is the oligopsoni market structure, where farmers are at the lowest position so that farmers do not have bargaining position. The objectives of IbM program were to 1) Reduce farmers’ dependence on pesticides and chemical fungicides with the utilization of environmentally friendly pesticides 2) Design the fermentor to improve the quality of cocoa beans 3) Enhance the bargaining position of farmers through the active role of Farmer group (Gapoktan)  in the marketing chain of cocoa
