Abstract

This paper proposed adsorbent development by synthesizing polyurethane foam (PUF) using a simple method, mixing polyol with isocyanate and adding fillers of bentonite and magnetite to the PUF matrix. The study's main objective was to produce a PUF-based adsorbent with high reactivity to removeHg2+ in wastewater. This bentonite and magnetite filler-modified polyurethane foam (BMPUF) adsorbent was fixed in a bed column for the adsorption of mercury (II) ions from an aqueous solution. The effect of initial Hg2+ concentration on the removal rate and the effect of contact time on adsorption efficiency was investigated. Langmuir, Freundlich, and BET non-linear models were taken into account to determine the best adsorption isotherm fitting and obtain adsorption capacity, intensity, and pore volume. As a result, it followed the non-linear Freundlich model, and the average adsorption capacity and intensity were 0.466 mg/g and 0.923, respectively. The average BET-based pore volume obtained was 0.782 L/mg. The kinetics study showed that the non-linear pseudo-first-order kinetics model was more suitable for describing the Hg2+ adsorption kinetics. The maximum equilibrium adsorption capacity was 1.770 mg/g with the adsorption rate of 0.0013 min-1 based on the non-linear model. The effect of varying bentonite and magnetite ratio on adsorption isotherm and kinetics was also investigated. Overall, the potential application of BMPUF adsorbent in the adsorption of mercury (II) ions was demonstrated in the current study.

Abstract

Waxing gel is included in cosmetic epilation which can damage the skin barrier. To overcome this, it is necessary to add a composition that can moisturize, prevent irritation, and maximize its lifting power. In minimizing the possibility of irritation, it is necessary to add allantoin to waxing preparations as a calming agent that is safe for sensitive skin. The purpose of this study was to determine the effect of the of Hydroxyl Propyl Methyl Cellulose (HPMC) on the resulting waxing gel preparation including aroma, thickness, and maximum hair lift in certain areas of the body and to determine the best HPMC for removing unwanted hair. This type of research is experimental research with independent variables, namely HPMC variations of 0%, 1%, 2%, 3%, and 4%. The research procedure consists of preparation of tools, preparation of raw materials, and products produced. After that, several panelists made observations by giving questionnaires regarding aroma, viscosity and lifting power. The results showed that there was a comparative effect of the HPMC s used. Based on the observations of several panelists on the aroma, thickness, and lifting power of the waxing gel that has been made, it is known that at the HPMC 0% and 1% HPMC variables, it was found that many panelists stated that the waxing gel in these variables had a fragrant aroma, had a very rich texture. viscous and has very good lifting power compared to waxing gel variables , namely 2% HPMC, 3% HPMC, and 4%.

Abstract

Transforming household organic waste (such as leftover food, fruits, vegetables, and other organic materials) into eco-enzymes represents a pioneering community service initiative in Luthu Lamweu Village, Sukamakmur District, Aceh Besar, Aceh Province, Indonesia. This project aims to enhance environmental awareness and improve community welfare. The villagers of Luthu Lamweu possess significant potential in converting organic waste into valuable products. The research methodology employed a participatory approach, actively engaging the community in all stages, including awareness campaigns (socialization), training sessions, technical support for eco-enzyme production, and evaluation. The strategy involved collaboration with village authorities, facilitated through the Program Bakti Mahasiswa Teknik (PBMT) and lecturer-led community service (PkM) to ensure program sustainability. The community service outcomes indicated a substantial increase in the communitys knowledge, interest, and skills in managing household organic waste into eco-enzymes, with a success rate of 96.25% (rated from sufficient to very good). Furthermore, the program positively impacted the villages environmental quality by converting organic waste into valuable eco-enzymes.

Abstract

Kabupaten Aceh Jaya is a very potential Aceh patchouli production center. The development of the patchouli industry sector in Aceh faces serious challenges, especially the capacity building of farmers towards good agriculture practices, and innovation and technology. This study aims to identify the level of empowerment of farmers and the affecting factors. The study employed a questionnaire survey to 88 samples from 383 populations. Data analysis used a descriptive method and chi-square test. The results show that a low level of farmer empowerment is predominantly. The weakest elements are the ability to cooperate and solidarity; meanwhile, the ability to overcome obstacles is the highest, followed by the awareness and desire to change, and the ability to increase capacity to gain access. Farmer's perceptions on the group institutions, and program intervention have a significant association with empowerment, while the perception to characteristics of the social systems has no relationship. Therefore, the role of empowerment innovation is necessary for capacity building.

Abstract

Tanaman Kopi merupakan salah satu komoditas unggulan sektor pertanian dan perkebunan di daerah dataran tinggi Aceh. Budidaya tanaman kopi di Desa Tebes Lues, Kecamatan Bies, Kabupaten Aceh Tengah dilakukan disekitar hunian penduduk. Sehingga, desa ini dinobatkan sebagai Kampung Kopi pertama di Aceh dengan konsep “Farmer’s Home Stay.” Namun, COVID-19 membuat pengembangan wisata  di desa ini berhenti total dan belum ada kegiatan lanjutan pasca COVID-19. Untuk mengatasi masalah tersebut, pemerintah desa bekerjasama dengan Universitas Syiah Kuala (USK) melaksakan kegiatan pengabdian penugasan melalui KKN Tematik. Hasil observasi tim pengabdian menyatakan kurangnya pemahaman sumber daya manusia (SDM) di desa terhadap pengembangan potensi wisata. Untuk itu, tim menyusun kegiatan pengembangan SDM yang sesuai dengan kebutuhan dan keahlian masyarakat desa. Kegiatan pengabdian mengusung tema green economy yang terdiri dari edukasi pengembangan agrowisata dan promosi melalui media digital, pelatihan pembuatan website dan sosial media desa, edukasi tentang pelestarian lingkungan melalui kegiatan pemilahan sampah, serta pelatihan pembuatan produk-produk turunan kopi dan minyak nilam. Dari kegiatan ini dihasilkan 4 produk turunan kopi dan minyak nilam diantaranya parfum aroma kopi, balsam cair aroma kopi, lilin aromatherapy kopi, dan sabun cuci piring. Kegiatan ini mendorong motivasi dan keahlian masyarakat desa dalam pengembangan Kampung Kopi Tebes Lues.
