Abstract

Zeolite is a hydrated aluminosilicate mineral (solid) in which silicate ions (SiO44-) and tetrahedral alumina (AlO45-) combine to form a porous/hollow and negatively charged crystal structure. Natural zeolite can be isolated from several sources, such as volcanic ash, sand, rocks, and rice husks, to industrial organic waste. Zeolite catalysts can be synthesized through various methods such as sol-gel, hydrothermal, ionothermal, and alkaline fusion. The purpose of modifying zeolite catalyst material is to improve its catalytic capabilities and physical and chemical properties, which can be done by various methods, including sol-gel, hydrothermal, ionothermal, and alkaline fusion. The use of zeolite-based catalysts and their derivatives has been widely used in various chemical reactions and industries such as isomerization processes, molecular cracking, to the manufacture of biodiesel. The conclusion is that zeolite is a widely developed material because of its abundant quantity in nature, and it is relatively cheaper and can be modified so that it can be used in various chemical reactions.

Abstract

School-age children are classified as a critical age group, because at that age an individual is more susceptible to experiencing health problems. The health problems experienced by school-age children are very complex and varied, but according to many children who are sick today because of a lack of knowledge about personal hygiene. Socialization regarding the application of Clean and Healthy Living Behavior to students is a response to problems that occur which is carried out in order to increase students' awareness and knowledge so they can practice Clean and Healthy Living Behavior. This outreach was carried out to students of SDN 1 Masaran and SMPN 5 Kapuas Tengah, in Masaran Village, Kapuas Tengah District, Kapuas Regency, Central Kalimantan Province. The implementation method uses a qualitative method to identify the Clean and Healthy Lifestyle of school children at the elementary and junior high school levels. The activity was carried out in two stages, namely planning and implementation through lectures, questions and answers, and hand washing demonstrations. The PHBS socialization activities went smoothly and well, all students enthusiastically took part in the socialization activities regarding PHBS. The results of the service include an increase in students' knowledge regarding PHBS which is proven through the understanding of PHBS and the implementation carried out by students

Abstract

Food security starts from availability on a small scale, namely households. Utilizing the function of the yard as a medium used by the community to grow their daily needs of vegetables. Urban farming as a strategic concept in meeting household needs and food security for village communities. Urban farming is an implementation of the Community Empowerment Assistant Lecturer Program of the Faculty of Engineering of Palangka Raya University in partnership with the Religious Women of RW 02/RW 03, Pahandut Seberang Subdistrict. Urban farming is located in a residential area on the banks of the Pahandut Seberang River, Pahandut District, Palangka Raya City. The service aims to stimulate riverside communities to use the area in their yards to grow vegetables as a pilot project carried out in the courtyard of the Daruth Tayyibah Mosque. The method uses qualitative methods from the results of interviews with residents' needs and consultations with residents. The result of the service was the implementation of urban farming in the courtyard of the Daruth Tayyibah Mosque, Pahandut Seberang Subdistrict, from the initial stage, discussion activities were carried out with the Head of RT.03/RW. 02 and the community, conducting outreach to the women of Koran regarding the introduction of hydroponics through, and it is hoped that the results of the urban farming pilot project can be used by women in their home gardens to grow vegetables for daily needs, and in the long term as a business opportunity for riverside communities.

Abstract

This community service aims to improve the knowledge and skills of Posyandu cadres in stimulating the motor and sensory development of early childhood, especially during the golden period of development (age 0-6 years). This activity was carried out at Posyandu Rajawali, Kp. Dukuh Pinang, Baros, Serang Regency, involving 10 active Posyandu cadres. The methods applied in this program include counseling and training carried out for three consecutive meetings. The results of the activity showed that 80% of participants stated that this program was very good and provided significant benefits. The level of participant satisfaction was also quite high, with 40% stating that they were very satisfied, 50% satisfied, and only 10% feeling less satisfied. This program has proven effective in improving the competence and expertise of Posyandu cadres in supporting and stimulating the motor and sensory development of children at an early age. It is hoped that with the increased knowledge and skills obtained, Posyandu cadres can contribute more optimally in monitoring, stimulating, and supporting the development of early childhood in their environment.

Abstract

Metabolomics has emerged as a critical field in understanding biological processes and disease mechanisms, necessitating advancements in analytical techniques to handle complex biological samples. This review explores the global landscape of metabolomics, with a focus on the use of spectroscopy and spectrometry. Techniques such as UV-Vis and Fourier Transform InfraRed (FTIR) spectroscopy offer fast and cost-effective metabolite tracing but are limited by their sensitivity, particularly for low-abundance metabolites. Nuclear Magnetic Resonance (NMR) spectroscopy, despite being less sensitive than mass spectrometry (MS), provides unparalleled structural information, distinguishing metabolites with similar mass-to-charge ratios. NMR's capability to detect metabolites in the 1-10 µM range highlights its effectiveness in metabolomics. This review categorizes advancements in these techniques, starting with global contributions to spectroscopy, followed by detailed discussions on FTIR strategies for metabolite tracing, and concluding with NMR's qualitative and quantitative applications in metabolomics and disease diagnostics. The review underscores the continuous development in sample preparation and data integration, enhancing the accuracy and applicability of these techniques, positioning NMR and FTIR as essential tools in modern metabolomic research.

Abstract

Vitamin B3 mengacu pada dua senyawa utama, niasin dan nikotinamida, yang secara alami ditemukan dalam berbagai sumber makanan seperti daging, ikan, jeroan, dan biji-bijian. Kedua senyawa tersebut berfungsi sebagai prekursor penting dalam biosintesis koenzim NAD dan NADP, yang penting untuk hampir semua proses metabolisme dalam sel hidup. Meskipun sering dianggap dapat dipertukarkan dalam perannya sebagai vitamin, niasin dan niasinamida menunjukkan efek farmakologis yang berbeda. Studi klinis telah menunjukkan bahwa niasin dosis tinggi dapat meningkatkan profil lipid pada pasien dengan penyakit kardiovaskular, tetapi penggunaannya terbatas karena efek sampingnya. Sebaliknya, niasinamida banyak digunakan untuk mengatasi masalah kesehatan seperti jerawat, diabetes, dan gangguan neurologis, dengan profil keamanan yang lebih baik. Baru-baru ini, NR, bentuk baru vitamin B3, telah mendapat perhatian karena kemampuannya untuk secara signifikan meningkatkan kadar NAD intraseluler dengan toksisitas minimal. Tinjauan naratif ini bertujuan untuk mengeksplorasi perbedaan struktural dan fungsional, manfaat kesehatan, efek samping niasin dan niacinamide, serta peran NR yang muncul sebagai vitamin B3 generasi berikutnya.
