Abstract

The community in Habaring Hurung Urban Village, Bukit Batu District, Palangka Raya City, is grappling with the issue of accumulating household waste, primarily composed of organic waste. The prevalent practices of managing this waste, such as landfilling, burning, or haphazardly piling it around residential areas and roadsides, pose environmental and health risks. In response to this challenge, an initiative was undertaken to empower families in Habaring Hurung Urban Village through training sessions on creating disinfectants using eco enzymes derived from fermented organic waste. The method of implementing community service consists of the preparation stage, namely digging up information on training needs, and preparing materials and teaching aids; the implementation stage in the form of pre-final tests and training; and the last stage in the form of evaluation and reporting, took place on September 4, 2023, at the office hall of Habaring Hurung Urban Village. A total of 39 participants actively engaged in the training, displaying enthusiasm and a positive response. The results of the questionnaire also showed a fairly good level of satisfaction of all participants regarding the theme of the activity, the presentation was easy to understand, the participants' knowledge increased, and this activity should be continued by all participants where the percentage of participants who agreed showed a value of 56.4%. 51.3%, 66.7%, and 53% respectively. The ultimate goal of this initiative is to educate the local community on transforming organic waste into multifunction products for everyday use.

Abstract

Tuwung Village, Pulang Pisau Regency, possesses significant potential in the fisheries sector. However, the development of this sector is hindered by the reliance on expensive commercial fish feed, which limits profit margins from fish sales. Furthermore, organic waste generated from agricultural and livestock activities remains underutilized, posing a potential environmental pollution problem. To address these challenges, a training program on independent fish feed production utilizing organic waste and local resources has been implemented. This program aims to equip the KUPS Fisheries Group in Tuwung Village with the knowledge and skills to produce high-quality fish feed at a more affordable cost. Through this training, participants were introduced to the concept of utilizing household vegetable waste and motan fish from Lake Sabuah as alternative feed ingredients. Additionally, they received training in both conventional and mechanical fish feed production processes, employing a specially designed mixer unit. The program outcomes indicate that participants successfully grasped the concept of waste and local resource utilization and are now capable of producing fish feed independently. It is anticipated that this program will enhance the productivity and efficiency of fish farming businesses in Tuwung Village, while simultaneously mitigating the environmental impact of organic waste.

Abstract

Teknik elektrodeposisi umumnya diterapkan untuk memperoleh penampilan fisik, kekuatan struktural, dan keawetan logam yang baik. Tujuan penelitian ini untuk mengetahui potensial optimum pada elektrodeposisi tembaga(II). Elektrodeposisi menggunakan larutan elektrolit CuSO4 sebagai sumber ion tembaga(II), H2SO4 sebagai elektrolit pendukung, dan HNO3 sebagai depolarisator. Lempeng platina digunakan sebagai elektroda (katoda dan anoda) dengan variasi beda potensial yaitu 2, 3, 4, 5, dan 6 Volt selama 25 menit. Selama proses elektrodeposisi, peningkatan beda potensial larutan CuSO4 mempercepat pengendapan logam Cu, namun deposit yang dihasilkan kualitasnya semakin menurun (banyak yang terbakar dan tidak menempel kuat di katoda). Hasil penelitian menunjukkan bahwa kondisi elektrodeposisi optimum dicapai pada beda potensial 2 Volt yang ditunjukkan dengan tampilan deposit yang cemerlang, menempel kuat di katoda, dan memiliki permukaan rata.

Abstract

Abstrak SMK Kesehatan Muhammadiah merupakan sekolah farmasi yang didirikan pada maret 2017 dan mulai menerima siswa awal tahun pelajaran 2017/ 2018. Sebagai sekolah baru, SMK Kesehatan Muhammadiyah telah terakreditasi oleh Badan Akreditasi Nasional (BAN) pada 2019. Materi asam basa menjadi pilar penting dalam titrasi yang sering ditemui dalam bidang kefarmasian. Namun, kurangnya sumber belajar terutama prasarana menyebabkan praktikum di sekolah tidak terlaksana. Kendala praktikum yang sering dialami yaitu keterbatasan indikator kimia karena harganya mahal. Tujuan pengabdian ini adalah memberikan alternatif indikator asam-basa alami dari ekstrak bahan alam sebagai pengganti indikator kimia. Selain harganya lebih murah, bahan alam mudah diolah dan jumlanya melimpah. Beberapa jenis bunga seperti bunga sepatu, asoka merah, bougenville (bunga kertas) merah, bunga kencana ungu, dan kunyit diekstrak dengan etanol, selanjunya kertas saring seukuran kertas lakmus dimaserasi ke dalam ekstrak tersebut. Setelah kering dapat disimpan dan digunakan langsung untuk penguijian larutan asam – basa. Kegiatan pengabdian ini diikuti oleh 22 siswa pada tanggal 26 Januari 2023 di ruang aula SMK Kesehatan Muhammadiah. Kegiatan pengabdian yang diberikan berupa pemaparan indikator dan pembuatan, ciri bahan sebagai indikator alami, demontrasi dan pembimbingan pembuatan indikator alami. Hasil kuesioner menunjukkan tingkat pemahaman peserta dalam kategori baik (76,5 %). Kegiatan ini memberi tambahan pengetahuan bagi siswa dalam pemanfaatan bahan alam sebagai pengganti indikator sintetik. Abstract SMK Kesehatan Muhammadiah is a pharmacy school that was founded in March 2017 and began accepting students at the beginning of the 2017/2018 academic year. As a new school, SMK Kesehatan Muhammadiyah has been accredited by the National Accreditation Board (BAN) in 2019. Acid-base matter is an important pillar in titration that is often found in the pharmaceutical field. However, the lack of learning resources, especially infrastructure, caused practicum in schools to not be carried out. The practicum obstacle that is often experienced is the limitation of chemical indicators because they are expensive. Several types of flowers such as shoe flowers, red asoka, red bougenville (paper flowers), purple datea flowers, and turmeric are extracted with ethanol, and then filter paper the size of litmus paper is macerated into the extract. After drying, it can be stored and used directly for the presentation of acid-base solutions. This service activity was attended by 22 students on January 26,2023 in the hall room of SMK Kesehatan Muhammadiah. The service activities provided are in the form of exposure to indicators and manufacture, characteristics of materials as natural indicators, demonstration, and guidance on making natural indicators. The results of the questionnaire showed the level of understanding of participants in the good category (76.5 %). This activity provides additional knowledge for students in the use of natural materials as a substitute for synthetic indicators.

Abstract

Biofouling commonly occurred due to the accumulation of bacteria that blocked membrane pores, especially in fungal-derived membrane technology. Surface modification of Cerrena caperata fungal membrane was carried out in this study to enhance its antibacterial activity, which can be expected to prevent biofouling on the membrane surface. This modification is crucial to ensure the ability of the membrane to inhibit or kill pathogenic bacteria during water purification, ultimately producing safer water in the future. The membrane was synthesized from C. caperata mycelium cultured in potato dextrose broth for 4 weeks. Two modification treatments were applied: 1) deacetylation with 50% NaOH and 2) coating the membrane surface with 1% stearic acid. Both unmodified and modified membranes were characterized using Fourier Transform Infrared Spectroscopy. Antibacterial activity was tested against Escherichia coli, Bacillus cereus, and Staphylococcus aureus. The results showed that the most effective treatment for improving the antibacterial activity of membranes was deacetylation with 50% NaOH for 90 min, it might be caused the structure transformation of chitin to chitosan which have ability for antimicrobial efficacy. This research is expected to highlight the potential of fungi as a natural and sustainable raw material in the production of filtration membranes that are not only effective in water purification but also safer for both the environment and human health.

Abstract

Stunting is defined as a disruption in a child's growth and development. The prevalence of stunting must be continuously reduced. Therefore, various efforts are being made, such as providing adequate nutrition. One food source that is high in protein and high in calcium is the seluang fish (Rasbora Argyrotaenia). The majority of residents living along the river in Palangka Raya earn their living as fishermen. This fish is widely found and sold in the market, making it quite affordable. To increase the market value of this fish, innovations have been made in processing seluang fish, namely by making seluang fish powder. The processing method involves boiling the fish in a pressure cooker, drying it in an oven, and then grinding it into a powder. The resulting fish powder is blackish in color and has a distinctive odor. Training on making fish powder was conducted for residents living along the river, attended by 30 residents, and the participants were very enthusiastic about the activity.
