PROCESSING OF ORGANIC AND INORGANIC WASTE CAN INCREASE INCOME DURING THE COVID-19 PANDEMIC

The study aims to find out how far the waste management process in University of Muhammadiyah Mataram. The waste in University of Muhammadiyah Mataram has not been handled as well as possible. It can be seen that there are still many landfills that are not handled properly and waste is simply dumped beside the river which is next to University of Muhammadiyah Mataram. The research used a quantitative approach and observations were made from January 2021 to March 2021. The results of the researcher' observations found that all types of waste were simply thrown away. After the researcher conducted socialization and training for all janitors at the University of Muhammadiyah Mataram, plastic wastes such as plastic bottles from beverage packaging and others have been collected and then the Bintang Sejahtera waste bank came to buy the inorganic waste, while organic waste from food scraps, especially the largest organic waste contributor came from canteen of University of Muhammadiyah Mataram, and the organic waste is used for maggot caterpillars or maggots.


INTRODUCTION
Waste is an important problem that has not been resolved in Indonesia until now.
The number of additional wastes is increasing as the human population increases.
According to the Central Statistics Agency (BPS), plastic waste in Indonesia reaches 72 million tons/year (Febriadi, 2019). The number of the population continues to increase day by day, including the number of the population in Indonesia. Based on data from Worldometer, the population growth rate in Indonesia reaches 1.07%, which is considered high. The rapid population growth resulted in increasing economic, sociocultural, and industrial growth. This can also result in a shift in the quality and function of the environment that is not in accordance with its designation (Kusumaningrum 2020.) The waste has always been a problem until now. Currently, it is only collected for disposal in Final Disposal Sites (FDS), then piled up or simply burned. Seeing the various problems regarding waste, it is very necessary for us to process and utilize waste to make waste more useful. One of them is the potential for waste to be used as a basic material for making cement, bricks, maggot caterpillar cultivation, and other goods of high economic value.
However, this time researcher will conduct research on organic waste transformed into maggot caterpillars. The maggot caterpillar or immature fly is the larva of a butterfly.
Maggots are larvae derived from Black Soldier Fly (Hermatia Illucens, Stratimydae, Diptera) or BSF larvae (Putra & Ariesmayana, 2020 Processing of Organic ….. 169 Based on the problems above, the researcher and partners agreed to plan several activities, including: 1) Conduct socialization and training on waste sorting and processing of organic and inorganic waste so that it can become material of economic value; 2) Conducting a massive campaign on "waste is rupiah" within University of Muhammadiyah Mataram.

Waste
According to the definition of the World Health Organization (WHO) "waste is something that is not used, not used, not liked, or something that is thrown away that comes from human activities and does not happen by itself (Handayani, 2019).
In Law No. 18 of 2008 concerning waste management, it is stated that the definition of waste is the remainder of human daily activities and/or from natural processes in the form of solid or liquid (Waluyo et al., 2019).
Based on this description, waste has clear boundaries as something that is unwanted and comes from human activities and does not occur by itself (Rosmala et al., 2020).
Therefore, the waste contains the following principles: a) The presence of an object or solid material; b) There is a direct relationship with human activities; c) The object or material is no longer used.

Organic and Inorganic Waste
Organic waste is waste that can decompose or can be decomposed again with the help of other bacteria. However, untreated organic waste can also cause environmental disturbances in the form of unpleasant odors that interfere with comfort and cause the environment to look shabby. Therefore, although it can be decomposed easily, organic waste also needs to be considered carefully. Inorganic waste is waste that comes from the rest of human activities that are difficult to decompose by bacteria, so it takes a long time to be decomposed. The nature of inorganic waste that is difficult to decompose causes various problems because some waste will decompose in a period of hundreds of years while the amount of waste is increasing every day (Yogiesti et al., 2010).
The concept of this waste bank is not much different from the concept of 3R (Reduce, Reuse, Recycle). If in the 3R concept it is emphasized how to reduce the amount Processing of Organic ….. 170 of waste generated by using or recycling it, in this waste bank concept, the most emphasis is how to make waste that is considered useless and has no benefits can provide its own benefits in the form of money, so that people are motivated to sort the waste they produce (Samudi et al., 2018).
Waste management according to Law No. 18 of 2008 is a systematic, comprehensive, and sustainable activity that includes waste reduction and handling (Sekarsari et al., 2020). The impact of waste on the environment is that the liquid seepage of waste that enters the drainage or river will pollute the water. Various organisms including fish can die so that some species will disappear this causes changes in biological aquatic ecosystems.
Then in social and economic conditions, it will form an unpleasant environment for the community, for example: bad smells and bad views because waste is scattered everywhere.

Factors Affecting Waste Management
The current reality is that waste becomes difficult to manage due to various reasons: a) The rapid development of technology; b) Increasing the standard of living of the community which is not accompanied by a harmony of knowledge about solid waste; c) Increased operating; d) Inefficient and incorrect waste management habits cause water, air and soil pollution, thereby increasing the population of disease-carrying vectors such as flies and rats; e) Failure to recycle and reuse used; f) It is increasingly difficult to obtain land as a landfill for waste (Purwaningrum, 2016). The waste management in the past and present does not pay attention to non-technical factors such as community participation and counseling about healthy and clean living.

Barriers to Waste Management
The problem of waste management in Indonesia is a complicated problem because (Handayani, 2019): a) More and more people object that their area is used as a waste dump;

Maggot caterpillar
If you hear the word caterpillar or maggot, many will feel disgusted because these animals are considered pests and carry diseases. However, this one caterpillar, turned out to be a unique and useful caterpillar, different from caterpillars or maggots in general. These maggots are not ordinary maggots, but the larvae of the Black Soldier Fly (BSF). In the body, BSF contains natural antibiotic substances so that it does not carry disease agents (Putra & Ariesmayana, 2020).
Although classified as flies, BSF does not land in the waste and does not carry disease. Maggot BSF is an exciting and profitable innovation for breeders, farmers, and the wider community. BSF maggot can be used as fish and poultry feed and so forth. The use of maggot as fish feed can further excite consumption fish cultivation because the price is relatively cheap. For animal feed, maggot can accelerate the increase in livestock weight.

RESEARCH METHOD
The research approach uses qualitative method. The main tool is human, meaning that it involves the researcher himself as an instrument by paying attention to the researcher's ability in terms of asking, tracking, observing, understanding, and abstracting as an important tool that cannot be replaced by other means.  (Satori & Komariah, 2009). Informants were selected and assigned while in the field, using the "snowball sampling" technique. At last, the qualitative analysis techniques used data reduction, data display and draw conclusions.

RESULTS AND DISCUSSION
The existing waste must be managed in such a way so as not to cause unfavorable

Inorganic Waste
For inorganic waste, mineral water packaging is dominant, such as bottled and glass packaging. Since the socialization was carried out by researcher to students and janitors, the  After the construction of the cages and containers was completed, the pupae from BSF flies were transferred into the cages and the maggots and organic waste into the containers. After being transferred, the pupae of BSF flies that were already in the cage were given water regularly and fruit or orange peels to get water nutrition. After one week, The training was carried out at the same time as the practice of maggot caterpillar cultivation, where equipment and equipment for maggot caterpillar cultivation had been provided by the researcher. Alhamdulillah, the trial of the maggot caterpillar was successful, although the cocoons produced were not too much, only 2 kg, the cocoons were marketed at the bird market, there are those on Jalan Gelantik Cakranegara, Mataram City, West Nusa Tenggara. 83239 and sold for IDR 25,000 per kg.
Data analysis in this study begins with: Firstly, data reduction. Miles and Huberman explain that data reduction is a process of selecting, deciding, paying attention to simplification, abstraction, and transformation of raw data that emerges from written notes in the field. Secondly, the presentation of data (display) by Ardhana in Lexy J. Meleong.
Namely the process of organizing data, organizing it into a pattern, category, and a basic description. Thirdly, the researcher conducted further analysis of data reduction and data display to draw a conclusion.(Diah, Muawanah 2018)

CONCLUSION
Never underestimate waste because waste can connect other people's lives when it is difficult. Inorganic waste can be sold directly to junk collectors. It can have a higher selling value, so we need to polish it a bit as handicrafts so that it will have a good selling value. Likewise, inorganic waste, the smell is very strong from leftover food waste, but the waste can be used as maggot caterpillar cultivation which is very useful for farmers as a food mixture and can be given to poultry because it has excellent nutrition
