Organic waste is waste that contains carbon compounds that come from living things, such as fruit and vegetable waste. However, the community is still not able to manage it optimally, even though organic and non-organic waste can still be processed into useful products. This effective way can be realized through the manufacture of eco-enzymes that can be applied at the household level. Eco-enzyme is a liquid extract produced from the fermentation of vegetable and fruit residues with brown sugar as a substrate. The eco-enzyme has a strong sweet and sour fermented aroma due to the peels of oranges, pineapples, and papayas. This environmentally friendly enzyme can be produced using fruit peel, brown sugar, and water. Eco-enzyme solution when mixed with water, will react and can be used as a liquid disinfectant. Disinfectants commonly used are generally derived from synthetic chemicals in the form of artificial chemicals. One of the natural ingredients that can be used as a disinfectant is eco-enzyme liquid. This study aims to make a disinfectant using an environmentally friendly enzyme liquid, namely eco-enzyme. The method used in this research is a mixed method of fermentation of orange peel waste, pineapple and papaya, brown sugar, and water with a ratio of 3:1:10. Analysis for eco-enzyme pH, and Phytochemicals, while for disinfectants include pH, total phenol content with UV-Vis Spectrophotometer, hard water emulsion stability, and antibacterial test. All samples of the disinfectant product met the requirements of SNI 06 – 1842 of 1995, besides that, the best disinfectant product was found in a ratio of 1:10 which could reduce bacterial growth.

This study uses orange peel waste to create a biopolymer that can be used for different purposes. In order to achieve this, we evaluated various technologies for the production of the biopolymer, and tried to design the most environmentally friendly process possible. One of the reasons why this bioplastic should be manufactured is to participate in the replacement of common environmental hazardous plastic, which has been banned in many places. On the other hand, using orange peel as the main ingredient is an alternative and gives value to an organic waste that has limited use in circular economy solutions. In this research we present a methodology to create a bioplastic of orange peels. As a result, we obtained a biodegradable, flexible and resistant material to be used in the manufacture of containers, utensils, etc. In addition, it is a material that, given the raw materials used, is considered GRAS (Generally Recognized As Save), implying a non-toxic product that is safe for the consumer.

Wide application of nanoparticles motivates the need for synthesising them. Here, a nontoxic, eco-friendly, and cost-effective method has been established for the synthesis of silver nanoparticles using extracts of lemon peel (Citrus limon), green orange peel (Citrus sinensis), and orange peel (Citrus tangerina). The synthesised nanoparticles have been characterised using UV-visible absorptionspectroscopy, Fourier transform infrared spectroscopy, and transmission electron microscopy (TEM). The UV-visible absorption spectrum of these synthesised silver nanoparticles shows an absorption peak at around 440 nm. TEM images show different shaped particles with various sizes. Furthermore, the antibacterial activity of silver nanoparticles was appraised by a well-diffusion method and it was observed that the green synthesised silver nanoparticles have an effective antibacterial activity against Escherichia coli and Staphylococcus aureus. The outcome of this study could be beneficial for nanotechnology-based biomedical applications.

Blockage of septic tanks is one of the problems in the community related to the discharge of toilet waste produced. The use of synthetic toilet cleaners that are not environmentally friendly is one of the factors that can inhibit the process of decomposing organic waste. The existence of microbial killer ingredients in toilet cleaning materials that come into the septic tank will actually inhibit the growth of essential microbes that play a role in the perfection of the decomposition process. Lack of understanding of the community related to microbial processes in the processing of toilet waste is one of the factors inability of the community to overcome these problems. This community service aims to disseminate information related to the processing of organic waste, the role of microbes in the processing of toilet waste, how to make microbial formulas that play a role in the processing of toilet waste, as well as efforts to increase the creativity of the community to process their own waste to improve environmental sanitation and improve community welfare. The results of the training showed that the average pretest and post test scores of the cadres of Tenggilis Surabaya village experienced a significant increase in value with a mean value of 37.78 (pretest) to 62.22 (post-test). Toilet waste processing cadres have been able to make biotoilet products that can be used to process limbat toilets in their homes. The informationand insights they receive can be passed on to the community from each cadre.AbstrakPenyumbatan septic tank merupakan salah satu permasalahan di masyarakat terkait dengan buangan limbah toilet yang dihasilkan. Penggunaan pembersih toilet yang berbahan sintetik yang tidak ramah lingkungan merupakan salah satu faktor yang dapat menghambat proses penguraian limbah organik. Keberadaan bahan pembunuh mikroba dalam bahan-bahan pembersih toilet yang ikut masuk ke dalam septik tank justru akan menghambat pertumbuhan mikroba esensial yang berperan dalam kesempurnaan proses dekomposisi. Kurangnya pemahaman masyarakat terkait dengan proses mikroba dalam pengolahan limbah toilet merupakan salah satu faktor ketidakmampuan masyarakat dalam mengatasi permasalahan tersebut. Pengabdian masyarakat ini bertujuanuntuk mensosialisasikan informasi terkait proses pengolahan limbah organik, peran mikroba dalam pengolahan limbah toilet, cara membuat formula mikroba yang berperan dalam pengolahan limbah toilet, serta upaya meningkatkan kreativitas masyarakat untuk mengolah limbahnya sendiri guna meningkatkan sanitasi lingkungan dan meningkatkan kesejahteraan masyarakat. Hasil pelatihan menunjukkan bahwa rerata nilai pretest dan post test kader kelurahan Tenggilis Surabaya mengalami peningkatan nilai yang cukup signifi kan dengan rerata nilai dari 37,78 (pretest) menjadi 62,22 (post test). Kader pengolahan limbah toilet telah mampu membuat produk biotoilet yang dapat dimanfaatkan untuk mengolah limbat toilet di rumah masing-masing. Informasi dan wawasan yang mereka terima dapat di teruskan kepada komunitas asal masing-masing kader.

In 2007 and 2008 the field experiment was conducted to test the efficacy of three environmentally friendly insecticides against the Colorado potato beetle (Leptinotarsa decemlineata), with the aim of evaluating their effect on the yield of potato. 0.25 % water emulsion of Neem-Azal (active ingredient azadirachtin) was applied twice, while 3 % water emulsion of Aktiv (a.i. potassium salt of fatty acids) and 1 % water emulsion of Prima (a.i. refined rape oil) were applied eight times. In 2007, the potato yield was higher (25.3±3.2 t ha-1) than in 2008 (8.2 ± 0.8 t ha-1). In 2007 there were no significant differences in potato yield at different control measures and the yield ranged from 7.5 ± 1.3 t ha-1 (Aktiv) to 9.4 ± 1.8 t ha-1 (Prima). In 2008, the highest potato yield was recorded in Neem-Azal treatment (3.5 ± 0.7 t ha-1), while in two other insecticide treatments the potato yield did not differ significantly with control treatment neither with the Neem-Azal treatment. Potato tubers were classified into three fractions: fraction 1 (tubers <4 cm), fraction 2 (tubers between 4 and 5 cm), and fraction 3 (tubers > 5 cm). On average we produce 2.11 ± 0.06 t ha-1, 9.93 ± 0.53 t ha-1, and 13.17 ± 0.70 t ha-1 of potato in 2007, and 2.11 ± 0.20 t ha-1, 4.68 ± 0.37 t ha-1, 0.84 ± 0.29 t ha-1 of potato in 2008, respectivelly.

The industrialization process of oranges generates waste, which is inadequately disposed of; this produces adverse effects on the environment. Among the alternatives for valorization is the vermicomposting process, which consists of the degradation of organic waste through the action of earthworms and microorganisms. Therefore, this research aimed to study this process using orange peel (OP) waste at the laboratory level. For this purpose, it was necessary to determine the degradation conditions through the monitoring of physicochemical parameters (temperature, pH, humidity, organic matter (OM), total organic carbon (TOC), total nitrogen (TN) and the carbon/nitrogen (C/N) ratio). To balance the substrate’s nutrients, load material (LM) that included vegetable waste and eggshells was added to three different mixtures: M1 (50% OP + 50% LM), M2 (40% OP + 60% LM) and M3 (60% OP + 40% LM). To condition the substrate for earthworm (Eisenia fetida) activity, a previous precomposting process was performed. The results showed that all the mixtures fulfilled the requirements for a quality and mature vermicompost; however, the highest concentrations for TN were in the mixtures M1 and M2. The total time required for degradation of the OP waste was 13 weeks.
