Abstract

Community empowerment and household waste processing are two issues that need to be resolved by the government. An independent and educated society is an important pillar to support the development of country. Meanwhile, waste that continues to accumulate without processing has a negative impact on health and the environment. Public education about household waste processing can be a solution to the two problems above. Education was carried out at Junior High School YBPK Surabaya and residents of Dukuh Kupang Surabaya, and other participants who joined in a hibrid meeting with a total of 116 participants. Activities at YBPK Surabaya took place on 25 March and 5 August 2023 and activities at Dukuh Kupang Surabaya took place on 27 May and 26 August 2023. The types of waste processed are organic waste and used cooking oil, which are then converted into eco-enzymes and used cooking oil Activities are divided into 2 stages. there are community education activities and program sustainability monitoring activities. The community education activities includes presentation and workshop were hold in March 2023 at YBPK Surabaya Middle School and May 2023 at Dukuh Kupang Surabaya. The evaluation of sustainability program including individual practice and monitoring of activities was carried out in August 2023 at Dukuh Kupang Surabaya. Methods for implementing activities include presentation, practice accompanied by a mentor, individual practice, and monitoring program sustainability. Based on the analysis of participants' ability, the participant scores before and after the activity was increase. It means that this training succeeded in increasing participants' knowledge and skills in processing waste, especially organic waste and used cooking oil waste. A total of 72 out of 116 participants (62%) had processed household waste either individually or in groups. Activity evaluation data shows that these activities are necessary and on target to create an independent and creative society.

Abstract

Carbon paste electrode-modified imprinted zeolite X has been developed as a potentiometry and voltammetry sensor to monitor cholesterol levels in the body. This is crucial to detect early health risks caused by high cholesterol levels. The modified electrode was fabricated with a mass ratio of activated carbon, paraffin, and imprinted zeolite X of 12:7:1. Potentiometric measurement produced a linear dynamic range of 10−6–10−3 M, Nernst factor of 27.12 mV/decade, a detection limit of 1.12 × 10−6 M, precision of 99.7% (n = 3), and accuracy of 99.8% (n = 5). Using the electrode for up to 56 measurements over 6 weeks did not significantly decrease its performance. The presence of glucose did not interfere with cholesterol analysis by potentiometry. The modified electrode was applied to analyze cholesterol voltammetrically at the optimum deposition potential of 0.4 V, deposition time of 60 s, and a scan rate of 100 mV/s. Voltammetric analysis of cholesterol resulted in a detection limit of 7.2 mg/L (1.86 µM), precision of 96–99%, accuracy of 74–114%, sensitivity of 7.1 nA.L/mg/cm2, and recovery of 87.2% (n = 3). The glucose and urea in various concentrations cause less than 5% current deviations.

Abstract

Superhydrophobic silica coatings have gained enormous attention due to their significant contribution to self-cleaning, anti-fouling, anti-icing, anti-corrosion, and moisture-resistance. This mini-review provides an overview of silica surface modification, including functionalization, roughness control, and deposition methods. Functionalization aims to reach hydrophobic properties by the application of low surface energy compounds. Surface roughness control at the micro- and nano-scale across different scales also results in various surface topographies. The type of deposition technique also influences the coating surface properties, including roughness texture, adhesion, and coating thickness. This paper also explains the challenges and gaps of research rarely reported by previous studies, such as the stability of coating in harsh environments, scalability, cost-effectiveness, and sustainability. Furthermore, this article also addresses promising future innovations in developing long-lasting coatings, multifunctional properties, and economic points of view.

Abstract

The coastal community of Sine Beach, Kalibatur Village, Tulungagung, Indonesia, has long thrived on fishing activities. In response to this, a community development service explores the alternative utilization of coconut, particularly the production of Virgin Coconut Oil (VCO), as a means of economic diversification. By integrating scientific principles with local traditions, the community learned to extract VCO and create various coconut-based products. This initiative not only broadened economic horizons but also fostered environmental sustainability. The programs aims to give economic impact to residents in Pantai Sine Tulungagung.

Abstract

Pellets Sapu Grow merupakan hasil inovasi terapan dalam pengolahan ikan sapu-sapu (Pterygoplichthys pardalis) menjadi pakan ternak. Ikan sapu-sapu merupakan salah satu jenis spesies invasif terbesar di Kabupaten Gresik yang belum termanfaatkan dan menjadi hama bagi petani tambak, namun ikan ini berpotensi besar apabila di jadikan pakan ternak. Tujuan kegiatan ini adalah untuk menyelesaikan permasalahan masyarakat pesisir Gresik terkait pengelolaan populasi ikan sapu-sapu yang tidak dapat dijual. Kegiatan dilaksanakan di Desa Jambu, Kabupaten Gresik pada Bulan Agustus 2025 dengan sasaran petambak, peternak ikan lele, dan ibu rumah tangga. Metode pemberdayaan masyarakat dilakukan dalam tiga tahap yaitu sosialisasi dan edukasi, pelatihan teknis, dan praktik langsung (hands-on). Sosialisasi dan edukasi dilakukan di balai warga dengan pemaparan materi terkait cara pengolahan ikan sapu-sapu menjadi pakan pellet. Hasil kegiatan menunjukkan   bahwa   ikan   sapu   sapu mampu dimanfaatkan dengan baik menjadi inovasi alternatif untuk pakan ternak dan menjadi solusi dalam meningkatkan perekonomian masyarakat sekitar. Selain itu, masyarakat mendapatkan ilmu pengetahuan, motivasi dalam memanfaatkan ikan sapu-sapu sebagai sumber bahan baku bernilai ekonomi dan pendampingan kegiatan dalam memasarkan pakan secara komersial. Pemberdayaan yang diberikan ini diharapkan dapat dikembangkan oleh masyarakat Kabupaten Gresik khususnya Desa Jambu untuk menjadi kawasan mandiri dalam membuat pakan ternak berbasis ikan sapu-sapu.

Abstract

This community service aims to assist by disseminating technology related to production equipment, which will help increase both the quantity and quality of products. Additionally, the program offers training on oil quality and teaches how to process waste cooking oil into soap. This community service activity is a way to achieve SDGs in the Decent Work and Economic Growth category through Small Entrepreneur and the Rural Economy. The activities were held in Ngelom Pesantren Village from April until September 2023 to overcome the priority problems that exist in the cracker entrepreneur group. The participants of this activity were a group of cracker entrepreneurs in Ngelom Pesantren Village, totaling 30 participants. Activities were carried out through research methods, workshops, and procurement of tools to improve the production process and quality of cracker products. The workshop topics covered halal certification of food products, oil quality standards, and making soap from waste cooking oil. The survey results showed that participants had a satisfaction level of 92% towards the activities and 93% towards the procurement of tools provided, and the production increased by 202.78%. In addition, the crackers are less greasy and the packaging is well-sealed, which can improve the quality of cracker products.
