Abstract

The cassava's production arm was quite abundant. Human ratings generally revolved around plantations and in rungs industries, much of which was said in cassava commodities. Most people consume cassava in the simple way of being boiled, fried, made in chips, and so on. In order not to dull the flavor of traditional foods but to be increasingly ogled by the styrofoampurvets, it is possible to make the products of the Singkong processed innovation into cassava frozen. The public's devoted activity is to helping people improve the economy, providing added insight and skill to processing cassava through cassava frozen and helping people form a group of tapioca women (KWT). The method used in this dedicated activity is by counseling between socializing and training and by demonstrations of Singkong frozen production. This activity involves women of family welfare development and housewives in three neighborhood associations is number 01, 02, and 03 at citizens association 12, Mentangor village districts,Tenayan Raya city districts. The result of this activity is that the target public seems enthusiastic about the material presented and has increased participants' knowledge and insight on assava frocenas are 100%.

Abstract

Fly ash is one of the byproducts of palm oil mill. The silica extracted from fly ash can be utilized for the synthesis of ZSM-5 by hydrothermal methods after fusion pre-treatment with NaOH. This study aimed to obtain ZSM-5 and determine the characteristic of the synthesized ZSM-5. The synthesis was performed at various composition molar ratio of SiO2/Al2O3 with addition of PEG-400 as template on temperature 100°C during hydrothermal process. The analysis using XRD showed that the two of three synthesized zeolites were ZSM-5 with crystallinity 67.63% and 28.53%. Analysis using FTIR spectroscopy on synthesized ZSM-5 detected many groups including T-OH hydroxyl groups (Si-OH/Al-OH), TO groups (O-Si-O/O-Al-O) and pentasil groups are typical of ZSM-5. From analysis using pyridine adsorption, it can be concluded that the increases ratio of SiO2/Al2O3 causes the number total acid side of the sample increased.

Abstract

Mini biopori is an innovative and efficient technique for producing biocompost. This technique utilizes used containers that are environmentally friendly, allowing the community to independently process household organic waste. In addition to reducing waste, this technique also produces fertilizer that is beneficial for horticultural plants. The purpose of this community service activity is to provide knowledge and insights to the community about the application of mini biopori technology in used containers for horticultural plant production, enhance the community's skills in applying mini biopori technology, utilize the biocompost produced from biopori infiltration holes for planting horticultural crops, and assist the community from an economic aspect (increasing community income) by using simple and inexpensive materials to produce high-value horticultural plants. This activity is conducted in Sungai Berbari Village, Pusako District, Siak Regency. The methods of this community service consist of several stages, including preparation, training through lectures and discussions, practical implementation of the mini biopori technique, and evaluation, which considers the conditions before and after the training activities. The results of this activity indicate that the participants have a better understanding of the biocompost production process and the benefits of the mini biopori technique. All participants (100%) considered the mini biopore technique training to be very beneficial, indicating that this training has successfully provided added value to the participants. A total of 70% of the participants showed an interest in applying the mini biopore technique in their homes. The mini biopore technique is considered effective in managing organic waste, producing beneficial fertilizer, and has the potential to reduce dependence on chemical fertilizers. Additionally, implementing this technique can lower agricultural production costs, increase crop yields, and contribute to long-term economic well-being in the community.

Abstract

Plastic waste originating from commercial sources presents significant environmental challenges, leading to the creation of biodegradable alternatives derived from renewable materials. This research investigates the feasibility of utilizing cassava peel starch (CPS), an agro-industrial by-product, as a foundational material for bioplastic manufacturing. To overcome the limitations of pure starch, such as brittleness and insufficient water resistance, a bioplastic was produced through solvent casting by combining a blend of chitosan, a natural biopolymer, and polyvinyl alcohol (PVA), a synthetic polymer, to improve its mechanical and physical properties. CPS was extracted and then analyzed for yield, moisture, and starch content. The interactions among components in bioplastics were examined utilizing FTIR and SEM techniques. FTIR analysis revealed physical interactions devoid of chemical bonding, whereas SEM demonstrated heterogeneous surfaces characterized by cracks. Among the five formulations, the formulation containing 5.0 g of PVA and 1.5 g of chitosan (F5) exhibited optimal performance, characterized by a thickness of 0.25 mm, a tensile strength of 11.95%, an elongation of 17.83%, and a biodegradation rate of 49.16% after 12 days.  The material met JIS Z 1707:1997 standards for mechanical properties, although it did not fully comply with biodegradation requirements. The novelty of this research presents to the valorization of cassava peel starch as local-agro industrial waste into bioplastics enhanced with chitosan and PVA, revealing a cost-effective, renewable alternative that meets key mechanical standards while advancing sustainable plastic innovation. The results indicate that CPS-based bioplastics, when combined with suitable polymer matrices, offer a feasible and sustainable substitute for conventional plastics.
