Abstract

Biobriket cangkang dan pelepah kelapa sawit merupakan salah satu energi alternatif untuk menanggulangi krisis energi. Studi ini bertujuan untuk mengetahui bagaimana pengaruh komposisi bahan dasar briket cangkang dan pelepah kelapa sawit terhadap kualitas briket yang difabrikasi. Fabrikasi briket dalam penelitian ini dilakukan dengan tiga variasi campuran yaitu 700g CKS + 300g PKS, 600g CKS + 400g PKS, dan 500g CKS + 500g PKS. Pengujian dilakukan untuk mengetahui lama waktu pemakaian dan nilai kalor dari briket, dari tiga variasi campuran  didapatkan waktu pembakaran terlama mencapai 150 menit dengan lama waktu penyalaan awal, yaitu   2 menit. Hal ini dapat dipengaruhi oleh kerapatan dan kandungan air pada briket. Nilai kalor juga mempengaruhi kualitas dari briket. Berdasarkan Hasil analisis nilai kalor, diketahui briket yang telah difabrikasi dengan campuran cangkang dan pelepah kelapa sawit berkisar 1,746 kalori hingga 2,521 kalori. Hal ini disebabkan oleh komposisi campurannya dimana, briket dengan campuran cangkang kelapa sawit lebih banyak dari pelepah kelapa sawit memiliki nilai kalori lebih besar.

Abstract

Dalam penelitian ini, telah dilakukan penumbuhan grafena dengan menggunakan metode Hotwire-Plasma Enhanced Chemical Vapor Deposition (HW-PECVD). Metode ini merupakan metode kombinasi antara metode PECVD konvensional dan metode CVD termal dengan menambahkan elemen hot-wire. Plasma dibangkitkan dengan menggunakan frekuensi radio pada spektrum Very High Frequency (VHF) sebesar 70 MHz. Sampel grafena ditumbuhkan di atas substrat kaca SiO2 yang telah dilapisi lapisan katalis nikel dengan temperatur penumbuhan 300°C. Grafena yang dihasilkan dianalisis dengan menggunakan spektroskopi Raman. Spektrum Raman sampel menunjukkan bahwa sampel yang dihasilkan telah mengandung struktur grafitik yang ditunjukkan oleh keberadaan pita G yang tajam, disertai dengan pita D yang menunjukkan bahwa sampel tersebut juga mengandung sejumlah cacat pada struktur grafitiknya. Sementara itu, pita 2D yang tampak dalam spektra Raman masih relatif lemah yang memberi indikasi kualitas sampel yang buruk, mengandung banyak cacat, dan berukuran nanokristalin. Walaupun demikian, hasil ini menunjukkan adanya potensi besar untuk dapat menumbuhkan grafena pada temperatur rendah melalui metode HW-PECVD yang digunakan melalui optimasi parameter-parameter penumbuhan lebih lanjut seperti tekanan penumbuhan dan laju alir gas sumber termasuk mengoptimasi ketebalan lapisan katalis nikelnya.

Abstract

Clean fresh water is one of the basic needs that is difficult to obtain by the Suli-suli community, so the local community collects rainwater or buys it to get fresh water. . The dominant service location is close to the coast and Karst mountain so that the local community is increasingly difficult to obtain fresh water. So to help the Suli-suli community obtain fresh water, a groundwater search service was carried out. The service provider conducted measurements using a geoelectric resistivity tool with the Wenner-Schlumberger method approach with a span of 147 m per measurement path. The results obtained that the presence of groundwater was obtained at a depth of 2-15 meters. However, there are several points where there is also brackish water, this is because the service location is close to the coast so that seawater intrusion occurs which forms brackish water, but after a depth of 5 meters down the brackish water is no longer visible. From the results of this service, it is hoped that it will be a reference for the community in finding and making freshwater wells, in order to meet the need for clean water.

Abstract

Landslides are a type of natural disaster that often occurs in areas with hilly and mountainous topography with high rainfall. Tamalalang Timur Hamlet, Gowa Regency, South Sulawesi is a geomorphologically located area in a hilly area with high rainfall, so it has a significant potential for landslides. This community service activity aims to analyze the structure of the soil layers in Tamalalang Timur Hamlet using the Wenner-Schlumberger configuration geoelectric resistivity method and provide socialization to the community about the categories of landslide-prone areas. Measurements were carried out in areas that represent the topographic and geological conditions that are the target of the service. The results of resistivity data inversion indicate that the soil layers in the area are dominated by water-saturated clay with a low resistivity value of 1–12 Ωm, followed by sandy clay soil layers (12.7–50 Ωm) and bedrock (>100 Ωm). From the interpretation, it provides a strong indication of the existence of a tiered rock layer system, with the potential for aquifers located in the middle layer with moderate to low resistivity, while the base layer is made of hard, impermeable rock. On the one hand, the public needs easy-to-understand information about the early signs of landslides. Some people are more familiar with the dangers of flooding than local landslides or land subsidence. Therefore, this activity provides practical benefits in the form of increased disaster literacy.

Abstract

Environmental sanitation and unhealthy dietary patterns can increase school-age children’s vulnerability to infection, micronutrient deficiencies, and excessive weight, ultimately affecting growth, development, and learning readiness. This community service program aimed to improve children’s knowledge and skills in environmental sanitation and balanced nutritious food consumption through SANITA-GIZI. The program was implemented at UPT SDN 179 INP Balang Desa Mangadu, Kecamatan Mangarabombang, Takalar Regency, involving 30 school-age children. An educational and participatory approach was applied through interactive learning, handwashing demonstrations, waste-sorting simulations, food-grouping games, balanced-plate practice, and teacher-assisted mentoring. Evaluation used pretest–posttest questionnaires, skill observation sheets, and participant response forms. Data show that the mean knowledge score increased from 58.3 to 86.7, equivalent to a 28.4-point improvement and an N-gain of 0.68 (moderate category). Correct handwashing practice increased from 26.7% to 90.0%, while the ability to arrange a balanced nutritious plate increased from 23.3% to 86.7%. The program received a very positive response from 93.3% of participants. SANITA-GIZI may serve as a simple, contextual, and replicable school education model. Nevertheless, claims concerning growth and developmental optimization require sustained mentoring and longer-term anthropometric and dietary-behavior assessments.

Abstract

Riverbank erosion is a significant environmental issue that affects ecological systems, socioeconomic conditions, public health, and community resilience. Despite its widespread impacts, its potential as a contextual learning resource in environmental education has received limited scholarly attention. This study aims to synthesize existing evidence on the impacts of riverbank erosion and examine how the phenomenon can be reframed as a contextual learning medium within environmental education. A Systematic Literature Review (SLR) adapted from the PRISMA guidelines was conducted using articles retrieved through Publish or Perish from the Scopus database. Using the keywords “riverbank erosion,” “contextual learning,” and “environmental education,” the selection process resulted in 10 relevant articles, which were analyzed through qualitative descriptive techniques. The findings reveal that riverbank erosion contributes to environmental degradation, damage to land and settlements, population displacement, and increased socioeconomic vulnerability. More importantly, this review highlights the educational value of riverbank erosion as an authentic environmental context that supports contextual learning, place-based learning, and environment-based learning approaches. By synthesizing evidence across environmental and educational studies, this review provides a conceptual linkage between local environmental challenges and meaningful learning experiences. The findings suggest that integrating riverbank erosion issues into environmental education can foster environmental literacy, critical thinking, and students’ awareness of sustainability challenges, while offering educators a framework for connecting real-world environmental problems with classroom learning.
