Abstract

Water pollution caused by heavy metal mercury is a serious problem today. This study aims to utilise jackfruit wood waste as a natural adsorbent in overcoming the problem of water pollution due to heavy metal mercury. The methods in this research include jackfruit wood preparation, hydrochar synthesis through pyrolysis, hydrochar activation, wastewater preparation, batch adsorbent optimum conditions, and dynamic adsorption process (Fixed-Bed Column). The results showed that the optimum adsorption condition was reached at 0.4 M HCl concentration, pH 3 and 80minutes contact time. The study also showed that the adsorption kinetics followed a second-order pseudo model with a rate constant of 1.712 x 10-2 g/mg.min. The research data also showed conformity with the Langmuir isotherm model, with an adsorption capacity of 63.036 mg/g. The results of this study prove that jackfruit wood waste is effectively used as raw material for making activated carbon for wastewater treatment applications in removing heavy metal mercury.

Abstrak: Pelatihan pembuatan lilin aromaterapi memiliki peran penting dalam meningkatkan keterampilan praktis dan kreativitas siswa. Kegiatan ini bertujuan untuk meningkatkan kemampuan hardskill siswa dalam pembuatan lilin aromaterapi, sehingga mereka memiliki bekal keterampilan yang dapat diterapkan dalam kehidupan sehari-hari maupun sebagai peluang wirausaha. Metode pelatihan yang digunakan meliputi pemberian materi secara ceramah dan praktik langsung pembuatan lilin aromaterapi. Peserta kegiatan ini adalah 80 siswa/i dari SMAN 1 Kasongan. Diakhir kegiatan pelatihan dilakukan evaluasi dengan pengisian angket oleh peserta untuk menilai pemahaman dan keterampilan yang diperoleh selama pelatihan. Hasil evaluasi menunjukkan bahwa 81,25% peserta memahami metode pembuatan lilin aromaterapi, sedangkan 90% peserta mampu membuat lilin aromaterapi secara mandiri. Dengan demikian, pelatihan ini terbukti efektif dalam meningkatkan keterampilan praktis dan kreativitas siswa.Abstract: The aromatherapy candle-making training plays an important role in enhancing students' practical skills and creativity. This activity aims to enhance students' hard skills in making aromatherapy candles, so they have a set of skills that can be applied in daily life as well as entrepreneurial opportunities. The training methods used include lectures and hands-on practice in making aromatherapy candles. The participants of this activity are 80 students from SMAN 1 Kasongan. At the end of the training activities, an evaluation was conducted with participants filling out a questionnaire to assess the understanding and skills acquired during the training. The evaluation results show that 81.25% of the participants understand the method of making aromatherapy candles, while 90% of the participants are able to make aromatherapy candles independently. Thus, this training has proven effective in enhancing students' practical skills and creativity.

Abstract

A community service activity entitled "Socialization and Education on the Dangers of Drugs for Students of SMPN 4 Tewah, Gunung Mas Regency, Central Kalimantan Province" was conducted as an early prevention effort against drug abuse among students. This outreach program aimed to provide a comprehensive understanding of the negative impacts of drugs from a health, social, educational, and legal perspective. The method used was interactive delivery of material through presentations, discussions, and question-and-answer sessions, enabling students to participate more actively and relate the knowledge gained to their daily lives. The results of the program demonstrated that it was well-run and effective. This was evidenced by a significant increase in student understanding based on pre- and post-test evaluations, with an understanding score of 94.8%. These findings demonstrate that the outreach and education on the dangers of drugs can positively contribute to raising student awareness of the importance of staying away from drugs. Thus, this activity serves not only as a learning tool but also as a strategic step in developing a healthy, productive, and integrated young generation.
