Abstract

The open mining method has the potential for the formation of mine water. Mine water is characterized by a high degree of acidity which affects the life of organisms and the quality of the environment indirectly or directly, therefore it needs to be managed. This study examines mine water management at PT Adaro Indonesia. The methods used in the research were field studies and laboratory experiments. Grab sampling is used to take water samples, with the test parameters being pH, Fe and Mn metals and total suspended solid (TSS). Data analysis was carried out quantitatively and descriptively. The mine water management used is in the form of a settling pond. The settling pond consists of several compartments, namely sedimentation pond, safety pond, treatment pond and mud pond. The quality of mine water management through a series of settling ponds obtained changes in pH to 6.07, Fe metal 0.0465 mg/l, Mn metal 1.3513, and TSS 35 mg/l with an efficiency of more than 50%. The quality of mine water produced after going through management has met the established regulations, namely Decree of the Minister of Environment and Forestry No. 1347/MENLHK/SETJEN/PLA.4/12/2022.

Abstract

Way Tuba sub-district, Way Kanan is one of the areas where the majority of people work as farmers. This profession is very vulnerable to direct sunlight exposure which has a negative impact on human health, especially the skin and eyes. The worst danger due to UV exposure that most often occurs is Non-Melanoma Skin Cancer (NMSC). Awareness of these dangers is still not fully understood by the community, so a program is needed that can increase understanding of the risks of direct sun exposure and skin health. Lecturers of the Cosmetic engineering, ITERA organized a program to increase skin health awareness through several activities such as counseling for PKK groups, training in making simple skin care from natural ingredients around the house and initiating the planting of a family cosmetic garden in the yard. Utilization of natural ingredients around the house can overcome skin damage at a low cost. In addition, with the cultivation of plants that maintain skin health in the home yard, it can be used at any time as prevention not just as treatment. Therefore, it is necessary to understand the types and ways of using natural ingredients around the house for the community, especially the PKK Group as a driving cadre in each village. Based on the results of the questionnaire, this community service program can increase community understanding up to 90% of representatives from 13 PKK groups in each village in Way Tuba District. Some plants were also cultivated directly through the initiation of a family cosmetic garden in one of the residents' yards. This is expected to be a trigger for other PKK groups in utilizing yard land in caring for skin health.

Abstract

Increased antibiotic consumption has exposed bacterial communities and environmental ecosystems to large amounts of antibiotic residues derived from the excretion of irrationally consumed antibiotics. This study provides an overview of antibiotic consumption patterns in hospital inpatients and the distribution of residues released into the environment. Medical record data was used to calculate the amount of consumption from hospital inpatients, and based on the type of antibiotics that have a DU90% value, ecotoxicological risk calculations were carried out to estimate the level of danger that occurs in the environment. A total of 27 types of antibiotics were prescribed, with a total consumption of 20504.42 Kg/year. Antibiotics such as ceftriaxone, cefixime, cefadroxil, and levofloxacin are the most widely used antibiotics based on medical record data. The results of estimating the release of antibiotic residues in wastewater obtained ecotoxicological risk values for algae, invertebrates, and fish greater than one (RQs>1). This condition indicates an ecotoxicological risk at the health facility site due to the release of antibiotic residues into the river water body from the WWTP outlet. The release of antibiotic residues into the water can result in ecosystem damage and pollution of the aquatic environment.

Abstract

The persistent presence of organic dyes like Congo Red (CR) in wastewater poses a significant environmental challenge. In this study, CeO2 nanofibers (CeO2-NF) were successfully synthesized via electrospinning followed by calcination as potential photocatalysts for the degradation of CR pollutants in aqueous solutions. The synthesized nanofibers were characterized using field emission scanning electron microscopy coupled with energy dispersive X-Ray Spectroscopy (FESEM-EDS) for morphological and elemental analyses, X-Ray Diffraction (XRD) for crystalline structure, and Fourier transform infrared (FTIR) spectroscopy for molecular properties. Photocatalytic degradation experiments were conducted under UVC light irradiation, with the CeO2-NF1, CeO2-NF2, and CeO2-NF3 samples achieving CR degradation percentages of 95.6%, 96.9%, and 95.2%, respectively, after 130 minutes of reaction time. Kinetic analysis revealed that the photocatalytic degradation followed pseudo-first-order kinetics, with rate constants of 0.020 min-1, 0.024 min-1, and 0.025 min-1 for CeO2-NF1, CeO2-NF2, and CeO2-NF3, respectively, highlighting the superior performance of CeO2-NF3. These results indicate that CeO2NF could serve as an effective material for the photocatalytic degradation of organic dyes, offering a promising approach for wastewater treatment applications.

Abstract

ABSTRAK Madu merupakan salah satu hasil hutan bukan kayu (HHBK) potensial yang menjadi komoditas unggulan dan memiliki nilai ekonomis untuk menunjang aktivitas perekonomian masyarakat. Salah satu pelaku bisnis madu, yaitu PT. Suhita Lebah Indonesia (SLI), memiliki masalah dalam penurunan kadar air madu. Mitra menggunakan oven dengan suhu 50˚C yang lama pengeringannya dapat berhari-hari. Proses ini memerlukan waktu lama yang beresiko dapat merusak komponen dalam madu. UMKM merupakan pilar penting sektor ekonomi nasional yang membutuhkan perhatian sebelum memasuki masa mapan. Masalah pada UMKM tentunya dapat menjadi ancaman perekonomian nasional. Oleh karena itu, pengabdian kepada masyarakat ini dimaksudkan untuk menerapkan teknologi tepat guna (TTG), yaitu pembuatan alat penurun kadar air madu dengan sistem cool drying. Prinsip alat yang dibuat adalah pendinginan dimana madu yang berada didalam ruang pengeringan diaduk dengan menggunakan piringan yang diputar menggunakan motor listrik. Di dalam ruang pengering dialirkan udara dingin dari Air Conditioner (AC) yang akan membawa partikel air dari madu dan dialirkan kembali ke AC dengan siklus tertutup. Udara lembab yang mengalir keluar dari ruang pengering akan masuk kembali ke AC untuk dikondensasi menjadi tetesan air yang akan ditampung dalam wadah khusus. Alat penurun kadar air madu yang dibuat telah terbukti meningkatkan efisiensi produksi dengan menurunkan lama proses pengeringan madu yang awalnya memakan waktu 7 hari dapat direduksi menjadi 1 hari. Pengabdian kepada masyarakat ini telah berhasil meningkatkan efisiensi produksi Mitra, sehingga dapat menjadi solusi strategis dalam upaya untuk mengoptimalkan pemanfaatan sumber daya alam Indonesia serta meningkatkan kualitas dan produktivitas produk kesehatan dari Indonesia. Kata Kunci: Madu, Alat Penurun Kadar Air, Kesehatan, Hasil Hutan, Teknologi Tepat GunaABSTRACT Honey is one of the potential non-timber forest products (NTFPs) which is a superior commodity and has economic value to support community economic activities. One of the honey business actors, namely PT. Suhita Lebah Indonesia (SLI), has a problem in reducing the water content of honey. Mitra uses an oven with a temperature of 50˚C which can take days to dry. This process takes a long time which risks damaging the components in the honey. MSMEs are an important pillar of the national economic sector that requires attention before entering a stable period. Problems with MSMEs can certainly be a threat to the national economy. Therefore, this community service is intended to apply appropriate technology (TTG), namely making a tool to reduce honey water content using a cool drying system. The principle of the tool made is cooling where the honey in the drying chamber is stirred using a disc that is rotated using an electric motor. In the drying room, cold air flows from the Air Conditioner (AC), which carries water particles from the honey and flows back to the AC in a closed cycle. The moist air flowing out of the drying room will re-enter the AC to be condensed into water droplets which will be collected in a special container. The device for reducing honey water content has been proven to increase production efficiency by reducing the length of the honey drying process, which initially took 7 days, which can be reduced to 1 day. This community service has succeeded in increasing Mitra's production efficiency, so that it can become a strategic solution in an effort to optimize the use of Indonesia's natural resources and increase the quality and productivity of health products from Indonesia. Keywords: honey, water reducer, health, forest products, technology
