Sodium-bearing Waste Treatment Technology Evaluation Report

Objectives : Black soldier fly larvae (BSFL) are organisms that effectively decompose various types of organic waste including food waste, and food waste treatment using BSFL is attracting attention as a sustainable waste treatment method. However, food waste discharged from Korea has a wide variety of properties, and its high salt concentration limits its treatment by BSFL. Therefore, to increase the efficiency of food waste treatment using BSFL, it is necessary to increase the quality of food waste as a production medium for BSFL. In this study, the ratio of protein and fat was adjusted by adding bean sprouts and wheat brans to food wastes treated at high temperature under vacuum, and whether such medium is suitable for rearing BSFL was investigated.Methods : To improve the medium, the ratio of protein and fat was adjusted to approximately 2:1 by adding bean sprouts and bran residue to food waste. Subsequently, the growth and development rate of BSFL reared on chicken feed, food waste, food waste + bean sprouts, food waste + wheat bran were measured. Also, the decomposition rate of each medium was analyzed.Results and Discussion : The growth rate of BSFL grown on food waste + wheat bran medium was similar to that of BSFL reared on chicken feed. The speed of development at day 7 was also the fastest for BSFL reared with food waste + wheat bran medium and chicken feed. These results suggest that the mixed medium to which wheat bran has been added to food waste has the potential to be used as a commercial medium for BSFL production. The survival rate of BSFL was 89% or higher in all media.Conclusions : When food waste was used alone, BSFL development was poor compared to that in media combined with agricultural by-products such as bean sprouts and wheat bran. Therefore, to use food waste as a rearing medium of BSFL, it is necessary to adjust the ratio of protein and fat by adding various agricultural by-products and reduce salinity. For the improvement of food waste treatment technology using BSFL, mass rearing of useful insects such as BSFL, and promotion of the use of agricultural by-products, additional research is needed to optimize the composition of rearing medium based on food waste.

The Center for Home Industry chips on Bandar Lampung. The problem of this is the waste that has not been managed properly, the chip waste IRT waste in the form of fruit peels, leaves, fruit stalks, humps has the potential to be made of high-selling value products, diversification can be in the form of hand sanitizer products. The purpose of this activity is to solve the Partner's problem by disseminating research results in the form of transfer of waste treatment technology into a hand sanitizer. The method used is lectures and discussions on the dissemination of research results, assistance in processing wastewater into hand sanitizer products. The need for partners to process waste products into products that have value in the form of making herbal solid soap, followed by liquid soap, hand sanitizer, natural anti-microbial, feed making, composting and liquid fertilizer. The percentage increase in knowledge and understanding of the material after the service activities is the utilization of waste (40%), making feed (50%), making hand sanitizer (70%).

Direct Use

Anaerobic Digestion (AD) is a waste treatment technology widely used for wastewater and solid waste treatment, with the advantage of being a source of renewable energy in the form of biogas. Anaerobic digestion model number 1 (ADM1) is the most common mathematical model available for AD modelling. Commercial software implementations of ADM1 are available but have limited flexibility and availability due to the closed sources and licensing fees. Python is the fastest growing programming language and is open source freely available. Python implementation of ADM1 makes this AD model available to the mass user base of the Python ecosystem and it [prime]s libraries. The open easy to use implementation in PyADM1 makes it more accessible and provides possibilities for flexible direct use of the model linked to other software, e.g. machine learning libraries or Linux operating system on embedded hardware.

Waste treatment technology is not less important for the business of Slaughterhouse (RPH). Various businesses and technologies have been done to handle this waste problem, especially for the rumen waste in RPH. One of them is utilizing the waste as an organic fertilizer. Bovine rumen bacteria are bacteria that originate from the contents of bovine rumen, with simple and inexpensive development techniques. This bacterium helps farmers in improving and developing an insightful agriculture on the preservation of soil fertility and natural resources. The study aims to identify bacteria and find out the diversity, properties, and characteristics of bacteria from the liquid organic content of rumen cows. Methods undertaken by observing colony morphology, colony selection and purification, Gram staining, spores staining, and biochemical testing. Of the four isolates identified there are two bacterial genus, three isolates RS1a, RS2a, RS2b including the genus Bacillus sp. aerobic and an isolates of RS1b including the genus Lactobacillus sp. the facultative of anaerobic. The four isolates of bacteria are able to grow optimum at pH 6.5 and the temperature of 370C is homofermentative.

This research aims to analyze the sustainability of two types of fishery pond polyculture of milkfish-tiger shrimp with and without mangrove integration on small-scale farms. Sustainability dimensions considered in this research included are the ecology, economy, social-culture, technology-infrastructure, and laws-institutions as the dimensions analyzed. The performance of each aspect was analyzed by using Multi-dimensional scaling (Rapfish) and leverage analysis. The result shows that the current multidimensional sustainability status of the fishery pond polyculture both with and without mangrove integration was less sustainable (sustainability index of 44.98 and 36.18 respectively). The result of leverage analysis indicates that out of 73 attributes, there were 16 and 23 sensitive attributes respectively that affect the sustainability of polyculture fishpond with and without mangrove integration. These attributes should be managed immediately in order to improve the sustainability index of fishery pond polyculture, this includes organic pesticides application, source of capital, the availability of seeds of milkfish and tiger shrimp, market location, selling price, waste treatment technology, availability of agribusiness facilities and infrastructure, aquaculture technology, information technology, standardizing the quality of fishery products, availability of micro finance institution and others.
