Manufacturing of biodegradable plastic has been conducted by blending polypropylene plastic waste and durian seed starch. Polypropylene plastic waste was refluxed by xylene solvent and durian seeds starch was prepared by precipitation method with hard water and aquadest. The composition of blends were 94:6, 92:8, and 90:10 (%w/w). The mechanical and thermal properties of the resulting plastics were characterized. Based on the test result, biodegradable plastics with the ratio of 94:6 met the expectation. The mechanical properties obtained were tensile strength of 25.722 N/m2 and elongation at break of 5.292%. Thermal properties analysis showed that the melting point temperature was 163.68Â°C and the decomposition temperature was 445.62oC.Keywords: biodegradable plastic, polypropylene plastic waste, durian seeds starch, characteristic.ABSTRAKPembuatan plastik biodegradabel dari limbah plastik polipropilena dan pati biji durian dilakukan dengan membuat serbuk limbah plastik polipropilena dengan metode refluks dengan pelarut xilena dan pemisahan pati biji durian dengan metode perendaman dengan air sadah dan akuades.

This research aimed to overcome the issue of plastic packaging waste that accumulates in nature because synthetic polymers cannot be easily unraveled by bacteria. Biodegradable plastics were produced by mixing waste of plastics of the low density polyethylene (LDPE) with starch of empty palm fruit bunches, modified with the addition of maleic anhydride as a crosslinking agent. To produce biodegradable plastics, different compositions of LDPE waste, starch of empty palm fruit bunch, maleic anhydride, and benzoyl peroxide were used, namely (90: 10: 1: 1), (80: 20: 1: 1), (70: 30: 1: 1), and (60: 40: 1: 1). Research stages consisted of extraction of starch from palm empty fruit bunch (PEFB); preparation of biodegradable plastic powder with the reflux method and xylene solvents; and making of biodegradable plastics using the press molding method. Based on the results of characterization, it was revealed that the optimum condition was generated by biodegradable plastics with the composition of LDPE waste, starch of empty palm bunches, maleic anhydride, and benzoyl peroxide was equal to 60: 40: 1: 1, which generated the tensile strength value of 6.9410 N/m2, the elongation at break of 3.1875%, the the melting point temperature of 103oC, and the decomposition temperature of 384oC. Besides, the thermal gravimetric test generated a residue of 12.6% and results of the analysis on morphological properties suggested that the starch distributed evenly.Keywords: Biodegradable plastics, LDPE waste, LDPE-g-MA, starch, palm empty fruit bunch.

This research was conducted with the aim to produce a biodegradable plastic from waste plastic polypropylene mixing with the starch of durian seeds by adding maleic anhydride as a crosslinking agent, and benzoyl peroxide as initiator. In this study, carried out with a variety of ingredients are added with a certain ratio that is successively waste Polypropylene, starch from durian seeds, maleic anhydride and benzoyl peroxide are (94:6:1), (94:6:1:1), (94:6:2:1), (94:6:3:1). Biodegradable plastic in the characterization of the analysis with the ability to decompose in nature biodegradable test, with embedding samples of biodegradable plastic produced into three types of soil, namely normal soil, ground litter and sand for 1 month. Each sample was observed a decrease in mass every 10 days. From Biodegradabel in nature results obtained mass loss that has been grown for 1 month is on the ground litter by 9.08% in the sample by varying the composition (94:6:1:1).

Batik Jembatan Akar Small and Medium Industry (IKM) endeavors to produce Root Bridge batik fabric, which is a defining feature of the IV Nagari Bayang Utara sub-district. In its production process, IKM Batik Jembatan Akar still relies on rudimentary and traditional equipment and lacks the means to handle textile waste, leading to its disposal in nearby ditches. While the current waste output may not be significant, its continuation poses a threat to the local environment. Insufficient awareness of the environmental impact of textile waste can result in environmental pollution issues and disrupt community harmony around IKM Jembatan Akar. Additionally, IKM Batik Jembatan Akar struggles to stimulate consumer interest in traditional batik amidst the abundance of low-priced printed alternatives. The limited demand for production means that this SME has yet to invest in technology and waste processing equipment for its batik cloth production. Politeknik ATI Padang Community Service initiative seeks to educate all IKM Batik Jembatan Akar employees on the importance of waste processing and online marketing strategies, while providing training on donated textile waste processing equipment to enhance sales value and mitigate environmental harm. The approaches employed in this community service endeavor include (1) comprehensive activity planning, encompassing location surveys, production assessments, and inventory checks; (2) the fabrication and testing of waste processing machinery; (3) educational workshops covering waste management in batik production and its environmental implications, alongside practical training in equipment usage; (4) evaluation of activity outcomes. The outcomes of this Community Service initiative include the provision of textile waste processing equipment and a heightened awareness of environmental conservation, facilitating the integration of waste processing equipment into batik production at IKM Batik Jembatan Akar.

Talang is a village in Gunung Talang District, Solok Regency, West Sumatera. Nagari Talang, which is located ± 15 km from the city of Solok and ± 50 km from the city of Padang, is the administrative center of Gunung Talang District. The livelihood of the population, in general, is farming, and a small part as traders (entrepreneurs) and government employees. With limited employment opportunities, it is very necessary to provide counseling and training to create jobs and advance industry in the trade sector in the Talang area by utilizing housewives to be able to have their income by producing superior products, namely liquid detergent, fabric softener, and deodorizer. These three products are the main products used in washing and ironing clothes. It is hoped that by producing these products, the community can be helped in terms of the economy, and in particular it can be used as a source of income for housewive organizations in opening laundry. In addition to making these products, the community service team also provides ideas and product marketing systems that can be developed in the Talang community.

Several MSMEs in Padang Panjang City are engaged in livestock and processed meat and poultry products. These MSMEs can still be said to be small businesses because they implement a pre-order (PO) system for marketing, the variety of products offered is quite diverse, but limited knowledge about quality meat processing and market demands related to food products that comply with halal principles, and effective marketing strategies are not yet well understood as seen from the product packaging which still looks simple. The purpose of this community service activity is for MSMEs to be able to develop and improve product quality, increase competitiveness in the market, and contribute to local economic growth. The ATI Padang Polytechnic Team provided assistance including the introduction of meat processing techniques to create new product variations such as good and halal sausages, selection of quality raw materials, and the right marketing strategies to increase product competitiveness. The activity was carried out on August 20, 2024. The results of the Community Service activities were shown from the questionnaire given to participants. It is known that MSMEs in Padang Panjang city have been able to understand about natural and artificial food additives, healthy and halal meat processing processes, halal certification, shelf life of processed meat products and effective marketing methods.
