Abstract

Blora and Grobogan are regions with higher production capacity of corn commodity compared to other regions in Central Java province. However, low number of technical irrigation and el-nino phenomenon have become the main threat for the sustainability of corn farming in both regions. During dry session, the top soil of the land are solidified which lead to higher difficulty for planting the corn seed using traditional tool. An improved design of the traditional seeder is then required to solve this problem to enable farmers plant corn seed during dry session. The objective of this research was to develop seeder prototype with “Tugal Dalam” type in Blora and Grobogan regions where the land have been categorized as marginal land during dry session. The proposed design is based on technical, ergonomic, economical, and social aspect. The qualitative approach was used to obtain the technical, ergonomical, economical and social aspect required by the farmer. Kansei Engineering is used to translate and evaluate the proposed design through some tests conducted on several group of farmers where they were requested to use 4 seeder design options and write their preference on each design option based on the mentioned aspects. Tests confirmed that the proposed design can be used to plant a corn seed at farmers desired characteristics. Kansei engineering also confirmed that ‘high speed’, ‘easy to operate’, ‘low price’, ‘easy to handle’ and ‘has a watering system’ were preferred by the farmers and determined their decision on buying and using the seeder tool. Keywords: kansei engineering,  marginal land, seeder development, tugal dalam

Abstract

Plant cultivation with a closed hydroponic system needs to be developed as a food production solution in the future. With this technology, plant growth parameters (including light parameters) can be adjusted according to needs so that plants can grow optimally. Red and blue light are needed for sorghum cultivation. This study aims to analyze the effect of the combination of red and blue LED lights on the growth of sorghum plants and determine the optimal ratio between the two light sources based on the plant growth rate in a closed hydroponic system. The plant growth parameters measured included plant height, stem diameter, number of leaves, leaf area, leaf color, wet weight, dry weight, water consumption, and morphology of sorghum plants. This research is conducted by constructing the nine combination of red and blue LED light with the control system placed inside each closed hydroponic box. The results confirmed that the use of red and blue LED light combinations has a significant effect on the growth rate of sorghum. The optimum combination of red and blue LED light is obtained from combination of R7:B1 with the conversion ratio of 9.53 kg fresh product per kg sorghum seed. Keywords: Closed Hydroponic System, Control Systems, Growth Optimization, Sorghum Plant, Red And Blue LED Light

Abstract

Cassava is one of the superior commodities in Selopamioro Village, Imogiri District, Bantul Regency, Special Region of Yogyakarta. Cassava’s high productivity in the Selopamioro Village is up to 2,75 tons/ha with total land area of 415 ha. However, this potential condition still faces various challenges in the sectors of farmers, production, quality, low selling prices, limited market accessibility. Processing cassava into modified cassava flour (Mocaf) is implemented innovation at Selopamioro Food Production House (FHP) for increasing cassava added value and its diversification products. The Selopamioro is also jointly managed by the farmer groups. However, mocaf production could produce wastewater which cause odor problems in the community and environmental pollution due to improper treatment. The mocaf wastewater is acidic and contains high organic matter. The community empowerment aimed to solve odor problems in the community, implement biodigester as sustainable wastewater treatment technology, create the Selopamioro FHP as a transferring knowledge center regarding food processing with environmentally sound, implement sustainable community empowerment model. The activity was carried out in July - September 2022 with periodic monitoring. Biodigester implementation has treated the mocaf waste water with removal percentages of BOD, COD, TDS, cyanide, total ammonia were 97,47; 96,53; 1,.94; 93,75; 97,17%, respectively and increased DO up to 614,29%. The community empowerment has successfully solved odor and environmental problems since biodigester implementation, in which no more complaints from the public. Sustainable community empowerment model and local food processing center with environmentally sound also have been implemented in the Selopamioro Village.

Abstract

Tea plantation biomass wastes, such as tea plantation pruning, shade trees, and woody weeds have not been utilized. The waste can be used as renewable energy in the form of wood pellets. The problem is the feasibility of biomass waste to be used as material for making wood pellets as energy. This paper aims to analyze the potential of tea plantation biomass waste as wood pellet material to meet energy needs. The research was conducted in a tea plantation owned by the Tea and Kina Research Center (PPTK). Quantification of biomass waste potential per unit area was conducted in the plantation using direct measurement method. Proximate analysis of each wood pellet variant of biomass waste was conducted to match the quality of Indonesian Wood Pellet Standard. The biomass waste potential in PPTK is 14,281 tons per year which can produce 8,186 tons of wood pellets per year. This potential can meet the needs of wood pellet consumption from the tea production process at PPTK which is around 1.8 tons / day for the tea processing process of 13 tons/day. Based on proximate analysis, the wood pellets produced have a calorific value of 4425 cal/gram, density of 1.35 grams/cm3, fixed carbon content of 85.2%, and volatile matter of 3.72%. These results confirm that the wood pellets comply with the National Wood Pellet Standard (SNI 8021:2014). This can be a model for the application of the Green Circular Economy concept in the plantation sector. Keywords:   Biomass pellets; Green circular economy; Renewable energy; Tea plantation waste; Wood pellets

Abstract

The decrease in sugar productivity was due to insufficient process of the sugar production process such as the low efficiency of boiler machine input energy. This study aims to analyze the potential use of Bagasse Briquetting Fuel (BBF) made from sugarcane milling waste at PT Madubaru as an attempt to obtain the optimal efficiency of boiler machine. Analysis of the effect of the adhesive concentration on the BBF quality was carried out to determine the optimal composition of the use of adhesive materials. Economic analysis was also conducted to determine the economic potential of BBF development. The analysis revealed that the BBF from Sugarcane milling waste has Calorific Value of 17,367-19,497 KJ/kg and density of 0.740-0.915 g/cm3. BBF with an adhesive variation of 1.25% is the BBF with the highest efficiency because it meets the needs of boiler fuel with the least amount of 100.8 tons/day for the operation of 1 boiler machine. The development of BBF from sugarcane milling waste has a selling value of Rp1.390.5,-/kg much lower than the existing biomass fuels found in the market. Keywords: Bagasse briquetting fuel; Boiler machine; Energy efficiency; Renewable energy; Sugarcane milling waste.
