Abstract

Plastic is the dominant packaging used by the public, so it has the potential to damage the environment. It is necessary to synthesize raw materials for making plastics that are degraded by microorganisms, namely bioplastics. Bioplastics are packaging materials that are synthesized from natural raw materials so that they can be degraded in the environment. The raw material used is corncob because it is abundant and the benefits are not maximized. Research is needed to examine the stages of the production process and the characterization of bioplastics from corncob waste. The purpose of this study was to examine the stages of the production process and the characterization of bioplastics from corncob waste. This study used a laboratory experimental method with descriptive analysis. The production of bioplastics consists of the stages of making cellulose, cellulose acetate, and bioplastics using the solution casting method. The stages of cellulose isolation include hydrolysis, delignification, pulping, and bleaching, which showed an increase in cellulose content from 32.14% to 79.36%. Cellulose is acetylated to become cellulose acetate and has an acetyl content of 11.70 ± 0.40% with a yield of 121.16 ± 0.98%. The production of bioplastics uses a composition of cellulose acetate and chitosan at 50%:50% (w/w) successively. The resulting bioplastic has a thickness of 0.345 ± 0.024 mm, a density of 0.83 ± 0.03 g/cm3, a moisture content of 13.13%, a biodegradation value of 95.19%, a water resistance of 205.57%, and is transparent. The mechanical properties of bioplastics include a tensile strength of 22.3 N/m, an elongation of 21.11%, and a modulus of elasticity of 0.307 Mpa.

Abstract

Sugarcane (Saccharum officinarum L.) is a plantation commodity that has an important role in the economy in Indonesia. The demand for sugar increases with the increase in population. Therefore efforts to increase sugar production by increasing the productivity of sugarcane, one of which is through the use of high quality seeds. Sugarcane Bud Chip seeds have the potential to produce sugarcane with high yields, but efforts to stimulate seedling growth really need to be increased. The use of Biostimulant from shallot extract needs to be tested on sugarcane seedlings because shallots contain the hormone auxin and vitamin B1 which are very necessary to increase the growth of sugarcane seedlings. Therefore this study aims to determine the effect of shallot extract concentration on the initial growth of sugarcane plants using the bud chip method and determine the best concentration. This study was conducted for 2.5 months and was designed using a non-factorial randomized block design with 5 concentrations of shallot extract including B0 (control/no extract); B1 (20%); B2 (40%); B3 (60%); B4 (80%). The parameters include the number of tillers, plant height, number of leaves, and root length. The results of this study indicated that the shallot extract gave a significantly different response to the growth of sugar cane seedlings, as seen in the parameters of the number of tillers, the number of leaves and root length. From the data obtained, shallot extract at a concentration of 40% was the best concentration for all parameters.

Abstract

Seed is an important component in increasing crop production and productivity. The availability of superior seeds of lowland rice nationally, including Central Sulawesi Province, is still very limited so that it becomes an obstacle in supporting the achievement of rice production. For this reason, an assessment of the seed supply model in the form of farmer groups is expected to be an alternative way to provide superior and quality rice seeds according to the wishes and preferences of farmers and available according to time. The research was carried out in three centers of lowland rice whose farmer groups have not been facilitated by the Department of Agriculture, both district and provincial. This study aims to 1. Determine the problem of fulfilling seeds at the field level and 2. To obtain a model of the seed production system at the level of farmers and farmer groups for the fulfillment of superior and quality seeds appropriately. The implementation of the activity consists of two stages: the first stage is the identification and characterization of seed potential and constraints and the second stage is the assessment of innovation and seed production technology at the level of breeder farmers and farmer groups. The results showed that farmers did not know about new high-yielding varieties including the procedures and requirements for plants to become seeds and difficulties in obtaining information related to seeds, so farmers planted existing varieties or expected for seed assistance. Yields and seed production at the three activity locations showed quite high yields, reaching 4.2 – 5.1 tons of seed/ha where in one ha production for seeds can supply seeds covering an area of ​​100 – 120 ha and can increase profits 2 to 3 times compared to grain production. In addition, the farmer group scale captive system can see the appearance of the plants that will be used as seeds

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

The soaring level of public consumption and the decrease in the area of ​​cultivated land forced farmers to innovate. One of the efforts to increase healthy food production is to utilize functional rice with soilless cultivation methods. This study aimed to examine the best water and husk ratio in soilless cultivation of two functional rice varieties. This study used a completely randomized factorial design (RALF) with 2 factors and 3 replications. The first factor was water and husk soilless media with a ratio of 6:1, 8:1, 10:1, 12:1, and 14:1, while the second factor was the Watu dodol A3 and Merah A2 varieties. The results showed that the 8:1 soilless water and husk media gave the highest performance on the number of panicle grains (231,5 grains) and the number of rice panicle grains (205,67 grains). In addition, there were significant differences in plant height, productive tillers, and panicle length between Watu dodol A3 and Merah A2.

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

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.
