Abstract

Demand for Robusta coffee is increasing every year, but this situation is not matched with the amount of its availability. This raises problems, especially those related to guaranteeing continuity of coffee quality, limited supply availability, and timeliness of sales. Therefore, this study aims to identify the structure of the Robusta coffee supply chain and analyze the efficiency of the Robusta coffee supply chain performance in Kubu Raya Regency. The method used to identify the structure of the supply chain is descriptive analysis, while the DEA method is used to analyze the efficiency of the members performance of the supply chain. The results indicate that the structure of the supply chain consists of farmers, collectors, wholesalers, and retailers. Overall, the results of the performance efficiency measurement show that the performance of the Robusta coffee supply chain is efficient. However, there are still 4 farmers and 1 trader with inefficient performance, namely DMU1,2,6, and 7 at the farmer level, while at the trader level it is in DMU 5. Therefore, improvements are needed to improve the performance of the supply chain actors by reducing the variable input and increasing the output variable

Abstract

This study aimed to determine the effectiveness of Beauveria bassiana in controlling Plutella xylostella pests. The first stage of the experiment was conducted in vitro at the Pest and Disease Laboratory of UMSIDA by testing the ability of B. bassiana at spore densities of 100, 103, 105, and 107 CFU.mL-1 in inactivating P. xylostella caterpillars. The field application test was carried out on land endemic to leaf caterpillar pests in Seloliman Village, Mojokerto, East Java Province, Indonesia. The experiment was arranged in a Randomized Block Design with four B. bassiana spore density treatments repeated four times. Observations were made on the intensity of attack as well as wet weight and dry weight of plants. Data analysis used ANOVA followed by Duncan's test at the 5% test level to determine differences between treatments. The results showed that B. bassiana effectively deactivated the activity up to 60.2% in the application with a spore density of 107. The application of B. bassiana reduced the intensity of P. xylostella pest attack to 63.41% and increased the wet weight and dry weight of kale leaves by 246.0%. and 305.8% compared without B. bassiana application. The application of this entomopathogenic fungus can be a solution for controlling pests on land that is endemic to leaf caterpillar attacks

Abstract

Pests and diseases of maize plants have the potential to cause crop failure. Lack of information and knowledge about plant pests and diseases and limited field extension workers lead to errors in diagnosing maize pests and diseases. This results in inappropriate crop management that decreases production. Therefore, farmers need a tool to detect pest and disease attacks through physical symptoms seen on plants in the field. This research aims to produce an Agricultural Information System, namely an android-based expert system to detect pests and diseases in corn plants. The method used is software with prototyping to get an overview of the application to be built through a prototype application design and then evaluated by the user. The research stages include; gathering needs, building prototypes, evaluating protoype, coding the system, testing the system, evaluating the system, and using the system.  The result is the symptoms of pest and disease attacks on corn plants in the field, can be detected through the form of symptoms that are matched with images and characteristics of symptoms displayed on the Agricultural Information System software installed on android-based mobile phones or Tablets. Test results from 28 respondents showed that the success rate of detection of pest symptoms on corn plants was 75%, and for disease symptoms was 90%.

Abstract

Coconut meat is the part that is mostly processed into coconut milk, occult oil, and copra. Downstream processing, such as VCO, is an opportunity to increase the economic value of coconut farmers. VCO contains lots of unsaturated fatty acids and antioxidants, which are good for body health. This study aims to determine the quality and antioxidant activity of VCO and its economic feasibility as a business. This research was carried out in two stages, namely the manufacture of VCO by fermentation using the addition of starter Saccharomyces cerevisiae in amounts of 1 gram, 2 grams, and 3 grams. Then the yield was calculated and tested for antioxidant activity, organoleptic color, taste, and aroma. Then the second stage is calculated financially for the VCO business. The data obtained were then analyzed descriptively. The results of the research conducted show that the production of virgin coconut oil (VCO) is enough to be used as a business; it will reach the BEP when it has sold 13 bottles or earned as much as IDR 312,918. For every rupiah spent, a sales profit of 4.79 will be obtained, with a profit per unit of production of IDR 1,187,082, so this VCO business is feasible to develop. The VCO fermentation, according to SNI 7381:2008, is the addition of 1, 2, and 3 grams of baker's yeast. But the high yield and aroma are found in the addition of 2 grams of yeast.
