Abstract

Produksi dan konsumsi masyarakat yang tidak dikelola dengan bijak telah menjadi pemicu utama timbulnya permasalahan sampah, baik di Indonesia maupun di dunia. Untuk mengurangi volume sampah sekaligus memberikan nilai tambah secara ekonomi, konsep 3R (reduce, reuse, recycle) menjadi solusi yang relevan. Sampah nonorganik dapat didaur ulang menjadi kerajinan atau produk daur ulang, sedangkan sampah organik dapat diolah menjadi pakan ternak, biogas, dan pupuk kompos. Kegiatan pengabdian kepada masyarakat ini dilaksanakan di wilayah RW 22 Notoyudan, Kelurahan Pringgokusuman, Kecamatan Gedongtengen, Kota Yogyakarta dengan tujuan memberikan edukasi kepada warga dalam mengelola sampah rumah tangga melalui pendirian bank sampah berbasis konsep 3R. Melalui kegiatan ini, diharapkan dapat meningkatkan kesadaran masyarakat terhadap pentingnya menjaga kualitas lingkungan serta mendorong pemberdayaan ekonomi melalui pemanfaatan sampah. Kontribusi konkret dari kegiatan ini antara lain adalah terbentuknya bank sampah dan tersampaikannya edukasi mengenai pengelolaan sampah kepada warga, yang diperkuat dengan bantuan mesin pencacah sampah untuk mendukung keberlanjutan program. Secara keseluruhan, kegiatan ini diharapkan dapat menciptakan lingkungan yang bersih, sehat, dan berdaya secara ekonomi.

Abstract

This study examines the effects of heat treatment on the hardness, tensile strength, and surface roughness of AISI 1045 steel during turning operations. The material was tested under three conditions: untreated, hardened (with water and oil quenching), and tempered. Results reveal that heat treatment transformed the microstructure from ferrite-pearlite to a combination of martensite, bainite, ferrite, and pearlite. Hardness increased from 52.83 HRC (untreated) to 80.17 HRC (water-quenching hardening) and 68.33 HRC (oil-quenching hardening). Tempering achieved the highest tensile strength at 1231.73 MPa with a hardness of 65 HRC. Surface roughness was lowest for tempered specimens at 700 RPM (3.6 µm), while water-quenching hardening at 1000 RPM resulted in the highest roughness (35.35 µm). Tempering is recommended for machine components such as shafts due to its optimal balance of mechanical properties, hardness, and surface quality.

Abstract

Streptococcus mutans is the prior bacteria causing dental caries. Suruhan (Peperomia pellucida) may prevent dental caries due to its antibacterial bioactive content. This study aims to identify the bioactive profile of Suruhan ethanol extract and its antibacterial activity against Streptococcus mutans. Bioactive compounds were analyzed using Gas Chromatography-Mass Spectrometry (GC-MS). Antibacterial activity was tested through an inhibition test using the well-diffusion method, the Minimum Inhibitory Concentration (MIC) test, and the Minimum Bactericidal Concentration (MBC) test. The most detected compounds in Suruhan ethanol extract were n-eicosane, n-hexadecane, and glycerol. There are also antibacterial bioactives such as phenols, flavonoids, alkaloids, and terpenoids. Inhibition test of 500 mg/mL extract showed a clear zone of 8.25 mm diameter. The MIC and MBC values were 50 mg/mL and 100 mg/mL, respectively. Based on the results, Suruhan ethanol extract shows potential as an antibacterial, although its inhibitory effectiveness could be better.

Abstract

One of the skills that needs to be equipped to prepare a quality generation that meets the criteria of the 21st century is scientific literacy skills and high-level thinking skills, including thinking skills. Scientific literacy skills and critical thinking skills in students can be built through local wisdom which is used as a learning resource. The use of teaching materials in the form of e-modules can encourage students to learn more actively. The aim of this research is to produce a science e-module based on local wisdom to improve scientific literacy and valid critical thinking skills of junior high school students.  The method used is of the research and development type by adapting the 4D model developed by Thiagarajan. In the 4D model there are 4, namely definition, design, development and dissemination.  The validation results which included aspects of content suitability, presentation aspects, language aspects, graphic aspects by three validators obtained an average percentage of 93% with a very valid category. This shows that the e-module that has been developed has the qualifications to be suitable for use.

Abstract

Staphylococcus epidermidis is increasingly recognized for its resistance to certain antibiotics, posing a significant threat due to its potential to cause infections. Plant extracts have emerged as promising alternatives owing to their diverse phytochemical composition. This study aimed to evaluate the antibacterial efficacy of the ethanolic extract of Arumanis mango leaves (Mangifera indica L. var. arumanis) against S. epidermidis and to characterize its metabolite profile using Gas Chromatography-Mass Spectrometry (GC-MS). Employing the disc diffusion method, the extract demonstrated inhibitory activity against S. epidermidis at a concentration of 2% (2 mg/ml). Subsequent GC-MS analysis identified phenols, flavonoids, and alcohols as the predominant bioactive compounds, consistent with their known antibacterial properties. These findings suggest that Arumanis mango leaf extract holds potential as a natural antibacterial agent against S. epidermidis and warrants further investigation for incorporation into natural antibacterial formulations.

Abstract

The issue of waste management in the Special Region of Yogyakarta has become increasingly complex following the closure of the Piyungan Final Disposal Site (TPA) in early 2024. One of the impacts is the increased burden of waste management at the community level. The Margo Rukun Association in Bantul is a self-reliant community that actively manages waste independently. The existing issues include limited resources and the lack of appropriate technology (TTG) in waste management. This community service activity aims to implement TTG to enhance the effectiveness of waste processing production processes, such as organic waste shredders, plastic press machines, and digital-based production management systems. The implementation methods include socialization, TTG application, and TTG usage training. The expected outcomes include significant improvements in waste management, particularly for recyclable waste. This initiative can positively impact community self-reliance and promote circular economy practices at the local level.

Abstract

Corruption is a phenomenon not easy to observe. Corruption theory and existing definitions are ambivalent, both in size and level. Mathematical models, and econometrics are prone to statistical errors. Fuzzy logic facilitates more humane modeling and analysis. Fuzzy logic is not bound by strong assumptions, as a solution to solve complex problems, and not precise, including corruption analysis. The main objective of this study is to measure corruption in Indonesia. The research method used fuzzy logic by specifying the Mamdani fuzzy inference system (FIS) model. FIS Mamdani was chosen because it is more human manner. Sources of secondary data used in this research from various institutions. The results show that corruption time series data can be produced. During the research year (1995-2020), corruption that occurred in Indonesia was 36.14 percent of real GDP per capita.
