Co-Digestion of Organic Waste Products with Wastewater Solids: Final Report with Economic Model

Rambutan (Nephelium lappaceum L.) is a seasonal fruit and is a native plant from Indonesia. No wonder if it's in the rambutan season, a lot of rambutan skin trash piles up on the road. This is certainly a problem if not addressed immediately. The purpose of this PKM is to save the environment from a pile of organic waste with new breakthroughs that are worth selling in increasing the growth of the creative economy. The new breakthrough is by processing rambutan skin into SUBKUTAN. The method of implementation in this PKM includes the planning, preparation of materials and materials, manufacturing of products, stages of promotion, marketing, and the evaluation phase with an implementation period of 5 months. The results of this PKM are SUBKUTAN candied products. We have marketed SUBKUTAN products both online and offline around Madiun, then we have also worked with various pharmacies, shops, and small shops. This product has various benefits that are good for health, specifically can reduce cholesterol, besides that this product has a fairly affordable price of Rp. 15,000.00. The output of our PKM is SUBKUTAN candied products, the publication of articles in the National Scientific Journal, final report, and progress report.

Biomass Stove

The stove is one technology that plays an important role in the utilization of energy at the household scale. The biomass stove studied was a blower system gasification stove. In the blower system, oxygen entering the combustion chamber flows continuously according to the needs of combustion. In this biomass gasification stove study, researchers will also use the biomass stove wall or thermal energy into kinetic energy for grinding blowers and charging systems. This study aims to obtain fuel by utilizing biomass or organic waste as biomass stove fuel and get the energy driving the blower and charging system by utilizing a thermoelectric generator system. biomass stoves used in this study use the principle method of Top-Lif Up Draft (T-LUD) Gasifier, a type of gasifier that matches the characteristics of biomass that has high volatile matter, where the stove is designed intended for biomass fuel from agricultural waste products and industry, boiling 1 kg of water is done using wood chips by varying the area of the air flow door, which is 50%, 75%, and 100%. Can be analyzed Comparison of the performance of the biomass cooker stove and the power generated by the thermoelectric generator, at each door width of the air flow results are different, this is due to the mass of fuel consumption and fire temperature. After calculating the highest thermal efficiency results obtained in the area of 50% air flow ventilation and obtained power generated 1.83 watts with 100% ventilation flow door area using wood chips.

The bioeconomy includes all sectors and systems that rely on biological resources (animals, plants, micro-organisms and biomass, including organic waste), their functions and principles. The use of new technologies in the national economy is a key moment, which will create opportunities for the production of high - quality products from bioeconomy represented by the different types of activities. In the paper presents some of the basic indicators (socio-economic) applicable in the regional economy of the country, based on the principles and factors specific to each region. The transformation of indicators towards the bioeconomy will give greater opportunities for social and economic prosperity in each region of the country according to its specific characteristics. Biomass is a kind of solar energy conserved in plant and animal organisms. Biomass as a resource includes waste products from animals and human activities. On earth, there is a certain amount of "dead" organic matter that can be used once as a non-renewable resource from organic fuels.

Rearing Conditions

Bioconversion is the process whereby nutrients are recovered from organic waste products, often by flies, to produce value-added products such as protein for animal feed and lipids for biodiesel production. Currently, research and industry focus on a select few fly species for use in bioconversion that are generalists in their feeding behaviour, the black soldier fly, Hermetia illucens L., and the housefly, Musca domestica L. More investigation is needed on species of flies that are more suited to underutilised waste streams, including meat processing waste. Species of flies that breed in carrion, such as blowflies (Calliphoridae) and flesh flies (Sarcophagidae) can be used to reduce meat processing waste and produce a valuable source of protein. In this review, we propose more investigation and use of a wider range of fly species for bioconversion of organic waste. Four blowfly species are recommended for use in the bioconversion of meat processing waste or a mixture of manure waste and meat processing waste. Chrysomya chloropyga (Wiedemann) is a large mammal carcass specialist and has been found to be effective at recovering nutrients from abattoir waste within four days and producing large larvae in the process. Chrysomya putoria (Wiedemann) and Chrysomya megacephala (Wiedemann) naturally breed in carrion and faeces, are associated with pit latrines and respond well under mass rearing conditions, with high egg production. These species would be recommended for a large-scale bioconversion facility that receives mixed waste streams including manure and animal remains. Lucilia sericata is known to produce antimicrobial compounds that assist in wound healing and has been frequently bred and studied and responds well to lab and mass rearing conditions. We recognise the potential obstacles to using alternative species in industrial-scale bioconversion facilities and pose future directions for research to overcome these challenges.
