Abstract

Sodium tantalum oxide doping lanthanum (La-NaTaO3) compounds were successfully synthesized by a sol-gel method and calcined at different temperatures. Tantalum chloride (TaCl5) was used as starting material and lanthanum nitrate (La(NO3)3.6H2O) as lanthanum source. X-ray diffraction (XRD) revealed that the calcination temperature strongly influenced the crystallinity of the prepared samples.The crystallite sizes of the resultant La-NaTaO3were in the range of 27-46 nm. The photocatalytic activities of the samples were examined for hydrogen production from an aqueous methanol solution under UV light irradiation. It was found that the photocatalytic activity of the La-NaTaO3 depended strongly on the calcination temperature. The range of calcination temperatures were 500, 700, and 900°C. The La-NaTaO3 sample calcined at 900°C showed the highest photocatalytic activity compared to the samplescalcined at the other temperatures. The rate of hydrogen production reached a value of 6.16 mmol h-1 g-1 catalyst.

Abstract

Transforming household organic waste (such as leftover food, fruits, vegetables, and other organic materials) into eco-enzymes represents a pioneering community service initiative in Luthu Lamweu Village, Sukamakmur District, Aceh Besar, Aceh Province, Indonesia. This project aims to enhance environmental awareness and improve community welfare. The villagers of Luthu Lamweu possess significant potential in converting organic waste into valuable products. The research methodology employed a participatory approach, actively engaging the community in all stages, including awareness campaigns (socialization), training sessions, technical support for eco-enzyme production, and evaluation. The strategy involved collaboration with village authorities, facilitated through the Program Bakti Mahasiswa Teknik (PBMT) and lecturer-led community service (PkM) to ensure program sustainability. The community service outcomes indicated a substantial increase in the communitys knowledge, interest, and skills in managing household organic waste into eco-enzymes, with a success rate of 96.25% (rated from sufficient to very good). Furthermore, the program positively impacted the villages environmental quality by converting organic waste into valuable eco-enzymes.

Abstract

Daun kelor (Moringa oleifera L.) adalah salah satu sumber minyak atsiri yang kaya akan senyawa bioaktif dan memiliki potensi besar untuk dimanfaatkan dalam berbagai industri, seperti farmasi maupun pangan. Oleh karena itu, pemilihan metode dan parameter ekstraksi yang tepat menjadi faktor penting dalam menentukan kualitas dan kuantitas minyak atsiri yang dihasilkan. Penelitian ini bertujuan untuk menginvestigasi pengaruh variasi massa bahan dan daya microwave terhadap rendemen ekstraksi minyak daun kelor melalui metode Microwave-Assisted-Extraction (MAE). Pada penelitian ini, proses ekstraksi dilakukan dengan menggunakan 300 mL akuades (pelarut); variasi massa daun kelor 20, 30, dan 40 gram; daya microwave 300, 450, dan 600 watt; dan proses ekstraksi selama 30 menit. Hasil penelitian menunjukkan bahwa peningkatan massa daun kalor secara signifikan meningkatkan rendemen minyak, sedangkan variasi daya microwave tidak memberikan pengaruh yang cukup berarti terhadap jumlah rendemen minyak. Rendemen minyak tertinggi diperoleh sebesar 37,90% dengan penggunaan massa daun kelor sebesar 40 grams dan daya microwave 350 watt. Hasil analisis GC-MS mengidentifikasikan bahwa komponen utama dari minyak hasil ekstraksi mengandung senyawa asam oleat dengan konsentrasi yang tinggi, yaitu sebesar 15.48%. Hasil analisis FT-IR menunjukkan keberadaan senyawa dengan gugus karboksilat pada panjang gelombang 3280.92 cm-1. Lebih lanjut, hasil uji sifat fisik produk, seperti densitas dan viskositas kinematik

Abstract

Luthu Lamweu Village, located in Sukamakmur Subdistrict, Aceh Besar Regency, holds great potential for sustainable agricultural development but still faces challenges in managing household organic waste. Fruit peels, which are abundantly available, are often discarded without proper treatment, leading to potential environmental pollution. This community service program aimed to enhance the communitys understanding and skills in processing fruit peel waste into liquid organic fertilizer (LOF) beneficial for agriculture. The activities consisted of four main stages: preparation of materials and tools, participant education, hands-on LOF production practice, and monitoring of the fermentation process. Participants, mainly women from the PKK community group, were actively involved in each stage of the program. The results showed that the participants successfully produced LOF independently using simple materials and a two-week fermentation process, yielding a yellowish-brown liquid with a mild fermentation aroma. The final product was distributed to the participants and applied to home garden plants. This program effectively increased community awareness of organic waste management and supported environmentally friendly agricultural practices in Luthu Lamweu Village.
