Abstract

Abstrak Kegiatan arisan merupakan tradisi sosial-ekonomi yang telah mengakar dalam masyarakat Indonesia, khususnya di komunitas keluarga. Arisan berpotensi menjadi media pemberdayaan ekonomi keluarga, namun praktiknya seringkali hanya bersifat konsumtif dan belum didukung oleh pemahaman manajemen keuangan yang memadai. Pengabdian ini menyasar Komunitas Ikatan Keluarga di Kelurahan Air Dingin, Kecamatan Bukit Raya, yang aktif melakukan arisan namun masih menghadapi berbagai kendala dalam pengelolaan keuangan pribadi dan usaha rumahan. Tujuan kegiatan ini adalah: (1) meningkatkan literasi dan keterampilan manajemen keuangan keluarga dan usaha kecil; (2) mendorong pemanfaatan dana arisan untuk kegiatan produktif seperti modal usaha atau tabungan; dan (3) membangun sistem pencatatan keuangan sederhana untuk anggota komunitas. Metode yang digunakan adalah Participatory Action Research (PAR) dengan pendekatan pelatihan dan pendampingan partisipatif, termasuk ceramah, simulasi, diskusi kelompok, dan refleksi. Evaluasi dilakukan melalui pre-test dan post-test serta umpan balik peserta. Dengan pendekatan yang kontekstual dan praktis, kegiatan ini diharapkan dapat menumbuhkan kesadaran finansial, meningkatkan kemampuan pengelolaan dana arisan secara produktif, dan memperkuat ketahanan ekonomi rumah tangga melalui model edukasi yang mudah direplikasi di komunitas lainnya. Kata kunci: manajemen keuangan keluarga; arisan produktif; literasi keuangan; usaha rumahan; pemberdayaan komunitas Financial Management Education in Family-Based Rotating Savings Practices: Enhancing Financial Literacy within Kinship Communities Abstract The activity of “arisan” (rotating savings and credit association) is a socio-economic tradition deeply rooted in Indonesian society, particularly within family communities. Arisan has the potential to serve as a medium for family economic empowerment; however, in practice, it often remains consumptive in nature and lacks adequate understanding of financial management. This community service program targets the Family Association Community in Air Dingin Village, Bukit Raya District, which actively conducts arisan but still faces various challenges in managing personal and home-based business finances. The objectives of this activity are: (1) to enhance family and small business financial literacy; (2) to encourage the productive use of arisan funds for activities such as business capital or savings; and (3) to develop a simple financial recording system for community members. Using a participatory approach that includes lectures, simulations, group discussions, and reflection, this activity is expected to raise financial awareness, improve the ability to manage arisan funds productively, and strengthen household economic resilience through an educational model that is practical and replicable in other communities. Keywords: family financial management; productive arisan; financial literacy; home-based business; community empowerment.

Abstract

The use of conventional solvents in the oil paint industry often leads to volatile organic compound (VOC) emissions and toxicity, so this study aims to evaluate the potential of Fatty Acid Methyl Ester (FAME) as an environmentally friendly alternative solvent. FAME is synthesised from vegetable oil through a transesterification reaction, then formulated into alkyd resin-based paints with varying binder content (40%, 50%, and 60%) to be compared with acetone solvent. The paint performance evaluation includes tests on drying time, gloss level, hiding power, and Whiteness and Yellowness Index. The results show that FAME-based paints have a much higher gloss level (10–26 GU) than acetone (3–6 GU) because their slower evaporation rate provides optimal levelling time, though this results in much longer drying time, namely 780–819 minutes. In addition, FAME has been proven to produce better covering power and a lower Yellowness Index (1.39–4.15) than acetone (4.09–5.74). This superiority is influenced by the nature of FAME, which minimises damage to the polymer binder and uniformly disperses pigments, preventing agglomeration. Overall, FAME has great potential as a sustainable paint solvent that can improve optical and physical properties, although its formulation still requires optimisation to accelerate drying.

Abstract

Peatlands in Riau Province have great potential as a water source, but their quality often fails to meet standards due to high organic matter content and levels of heavy metals such as iron (Fe), which can pose health risks. This study aims to evaluate the effectiveness of various types of activated carbon derived from agricultural waste and biomass in reducing iron (Fe) levels in peat water through a Systematic Literature Review (SLR) based on the PRISMA 2020. A total of 8 relevant articles from the Google Scholar and ScienceDirect databases were analyzed, covering the use of materials such as empty oil palm fruit bunches, bintaro fruit shells, bamboo stalks, tofu residue, shrimp shells, corn cobs, coffee grounds, and natural zeolite. The results of the study indicate that the activation process, whether physical or chemical (using activators such as H₃PO₄, HCl, or KOH), is crucial in enhancing the porosity and surface area of activated carbon to optimize adsorption capacity. The highest iron (Fe) reduction efficiency reached 99.66% and was achieved using corn cob activated carbon activated with 0.25 M HCl at 400°C. Overall, the use of biomass waste as an adsorbent is not only effective and economical in improving peat water quality but also supports sustainable waste management.

Abstract

Abstract. Industrial wastewater containing heavy metals such as Zn²⁺ ions is one of the hazardous pollutants that can pose serious risks to the environment and human health. The presence of Zn²⁺ in aquatic systems at high concentrations can lead to acute toxicity, thus requiring effective and sustainable treatment methods. Adsorption has become one of the most widely developed treatment approaches due to its advantages, including high efficiency, low operational cost, and environmental friendliness. This study aims to synthesize and characterize Fe₃O₄/activated carbon composites as adsorbents for the removal of Zn²⁺ ions from wastewater. Fe₃O₄ was synthesized through a coprecipitation method using FeCl₃·6H₂O and FeSO₄·7H₂O precursors, and subsequently combined with thermally activated coconut-shell carbon to enhance surface area and adsorption capacity. The composite was characterized using X-Ray Diffraction (XRD). Adsorption tests were conducted using various composite masses 0.04 g, 0.05 g, 0.06 g, 0.07 g, and 0.08 g to examine the effect of adsorbent dosage. The best performance was obtained at an adsorbent mass of 0.08 g with an optimum contact time of 75 minutes. Under these conditions, an initial Zn²⁺ concentration of 30 ppm decreased significantly, achieving a maximum removal efficiency of 91% and 84.63% under other test conditions. These findings indicate that the Fe₃O₄/activated carbon composite exhibits high effectiveness and selectivity in adsorbing Zn²⁺ ions and holds strong potential for development as a wastewater treatment material based on renewable and environmentally friendly local resources.Keywords: Activated Carbon, Adsorption, Coconut Shell, Fe₃O₄ Composite, Zn²⁺ Ions
