Abstract

Daerah Gambut di Kabupaten Banjar, Kalimantan Selatan merupakan lumbung padi untuk daerah Kalimantan. Setelah panen, gabah perlu dikeringkan agar dapat disimpan  dan siap untuk digiling menjadi beras. Masyarakat mengeringkan gabah secara tradisional yaitu dijemur langsung di terik matahari. Hal ini sangat bergantung terhadap cuaca. Pengabdian masyarakat ini bertujuan membuat alat pengering gabah berbahan bakar briket sekam padi. Pada saat uji coba, alat pengering gabah berbahan bakar briket dapat menaikkan suhu dalam kotak pengering dari 40oC menjadi 56oC dalam waktu 20 menit. Untuk menaikkan suhu dalam kotak pengering, kita hanya perlu menambah bahan bakar pada tungku pemanas.Abstract. The peat area in Banjar Regency, South Kalimantan is a rice granary for the Kalimantan area. After harvesting, the grain needs to be dried so it can be stored and ready to be milled into rice. People dry grain traditionally, namely drying it directly in the hot sun. This really depends on the weather. This community service aims to make a grain dryer powered by rice husk briquettes. During the trial, the briquette-fueled grain dryer was able to increase the temperature in the drying box from 40oC to 56oC in 20 minutes. To increase the temperature in the drying box, we only need to add fuel to the heating furnace. Keyword: Peat; Rice husk; Briquettes; Grain dryer

Abstract

This paper explains and demonstrates how to synthesize Cadmium Sulphide (CdS) nanoparticles (NPs) using brimstone. The brimstone is obtained from Ijen volcanic crater in East Java Indonesia and used as the source of sulfur gas (S2) instead of Na2S. The brimstone was crushed and dissolved in potassium hydroxide (KOH) solution while heated. Acetic acid (CH3COOH) was added, to release the S2 gas. The liquid-gas method was used to prepare the CdS colloid solution. In this study, the effect of variations in the concentration and volume of CH3COOH, temperature variation, and exposure time on the synthesis of colloidal solutions of CdS NPs will be investigated. The absorption edge of the CdS colloidal solution compared to the bulk material experienced a blue shift. This is the evidence of the formation of NPs in solution. It is confirmed by FTIR which shows a CdS absorption peak at 467 cm-1. The radius of CdS NPs was calculated using the Efros equation to obtain a result of approximately 2 nm. Particle size analyzer (PSA) provides a much larger particle size of 20.8 nm. It is assumed that the NPs were agglomerated. Several treatments given, such as varying the volume of CH3COOH, varying temperature, stirring, and varying synthesis time, did not affect the size of the NPs.  The cadmium sulfide produced would be used as photocatalist in water treatment application.

Abstract

Daerah Gambut di Kabupaten Banjar, Kalimantan Selatan memiliki lahan pertanian yang luas. Setiap kali panen, sekam padi akan terlihat menimbun di sekitar penggilingan padi. Biasanya sekam ini dibiarkan teronggok atau dibakar menjadi abu gosok. Pengabdian masyarakat ini bertujuan melatih masyarakat untuk membuat briket dari limbah biomassa yang ada di sekitar secara sederhana. Briket sekam padi tersebut dapat dimanfaatkan sebagai energi alternatif yang dapat dimanfaatkan untuk keperluan rumah tangga. Mengingat masyarakat yang tidak mau berbelit-belit maka briket dibuat dari sekam padi yang tidak dikarbonisasi. Untuk meningkatkan nilai kalor briket dibuat dengan damar sebagai perekat. Untuk alasan efisiensi briket dicetak dengan bentuk lempengan tipis. Pada saat sosialisasi, respon masyarakat sangat positif karena proses pembuatan briket yang mudah dan murah. Pada saat uji coba, masyarakat juga tertarik karena briket mudah terbakar dengan sedikit asap.Abstract. The Peat area in Banjar Regency, South Kalimantan has a large area of agricultural land. Every time it is harvested, rice husks will be seen piled up around the rice mill. Usually this husk is left sitting or burned to become ashes. This community service aims to train the community to make briquettes from biomass waste around them in a simple way. The rice husk briquettes can be used as an alternative energy that can be used for household needs. Considering that people don't want to be complicated, briquettes are made from uncarbonized rice husks. To increase the calorific value, briquettes are made with resin as an adhesive. For efficiency reasons, the briquettes are printed in the form of thin plates. During the socialization, the public's response was very positive because the process of making briquettes was easy and cheap. During the trial, people were also interested because the briquettes burned easily with little smoke. Keyword: Peat; Rice husks; Resin; Briquettes

Abstract

Fluff tea is the residual solid waste generated in the green tea industry and holds the potential for development as a solid fuel in bio-briquettes. This study transformed fluff tea into bio-briquettes utilizing biochar produced through slow pyrolysis. The study aimed to optimize bio-briquettes production from fluff tea using the Response Surface Methodology (RSM) approach through proximate analysis. The cylindrical bio-briquettes were produced using biochar particle sizes of 850, 500, and 150 μm, resin gum adhesive concentrations of 10%, 15%, and 20%, and immersion times in cooking oil of 0, 3, and 6 minutes. The results showed that the overall response by the p-value was <0.05, and the lack of fit was insignificant (p-value >0.05). The findings indicated that the calorific value of tea fluff rose from 4,482.56 cal/g to 6,374.98 cal/g after conversion to biochar. The optimum conditions for producing tea fluff bio-briquettes were a particle size of 850 μm, adhesive concentration of 11%, and immersion time of 5 minutes. The bio-briquettes exhibited a moisture content of 3.53%, ash content of 5.65%, volatile matter of 14.75%, fixed carbon of 76.14%, calorific value of 7,796.37 cal/g, combustion rate of 0.11 g/min, density of 1.22 g/cm3, and compressive strength of 35.57 N/cm2. Most tea fluff briquettes' properties had met Indonesia's briquettes standard. The production of bio-briquettes from tea fluff waste is a viable alternative fuel for both industrial and domestic applications.

Abstract

This research aims to investigate the performance of activated carbon from water chestnut (WC) as an Fe adsorbent on river water samples in South Kalimantan. The WC was carbonized at a temperature of 400 °C. Then the carbon was activated with two types of activators, KOH and H2SO4 solutions. The carbonization and the activation time were also varied in two different times, 1 and 2 hours. The electrical conductivity of Martapura River water was measured to investigate its condition or quality, and yielded about 0.56   or 5600 µS/cm. It is quite large compared to the standard 1000 µS/cm. After activated carbon treatment, the electrical conductivity is reduced by about 6.67 – 13.81%. For Fe adsorption, the reduction efficiency and adsorption capacity were in the range of 7.73 % – 22.94 % and 0.50 – 1.47 mg/g. The results showed that the prepared activated carbon is effective in adsorption and decreases the Fe metal content at room temperature.

Abstract

This study aims to develop innovative science teaching materials based on higher-order thinking skills (HOTS) to enhance students’ critical thinking skills on the topic of object classification. The research adopted the ADDIE development model, which consists of five stages: Analysis, Design, Development, Implementation, and Evaluation. The study involved 60 seventh-grade junior high school students as research subjects. Data were collected using expert validation sheets, student response questionnaires, and pretest-posttest instruments to assess students’ critical thinking skills. The results of expert validation indicated that the developed teaching materials were categorized as “highly valid,” with an average score of 92.5%, reflecting the quality in terms of content, presentation, language, and design. During implementation, students showed an increase in critical thinking performance. The average pretest score was 58.3, which improved to 78.7 in the posttest. A paired sample t-test analysis revealed a statistically significant difference between pretest and posttest scores (t = 8.624; p < 0.001), indicating the effectiveness of the developed material in improving critical thinking skills. Furthermore, student responses to the teaching materials were very positive, with an average score of 88.4%, suggesting that the materials were well-received and engaging. This study provides empirical support for integrating innovative HOTS-oriented learning materials into science instruction, particularly for foundational topics such as object classification. The findings contribute to the field of science education research and offer practical implications for the development of curriculum materials that foster critical thinking in junior high school students. These results can be used as a reference for educators and curriculum developers in designing effective, student-centered science learning tools.    Keywords: ADDIE model, critical thinking, instructional design, object classification, science teaching materials.
