Abstract

Kegiatan pengabdian masyarakat ini bertujuan untuk meningkatkan pemanfaatan limbah pertanian, khususnya cangkang kemiri, sebagai sumber energi alternatif melalui pelatihan pembuatan briket biomassa. Kegiatan dilaksanakan oleh Tim Pengabdian Masyarakat Politeknik Negeri Lampung (Polinela) di Desa Kedaung, Kecamatan Pardasuka, Kabupaten Pringsewu, yang melibatkan Kelompok Wanita Tani (KWT) Makmur Lestari dan anggota Dharma Wanita KPH Pematang Neba. Pelatihan dilakukan melalui metode edukasi, sosialisasi, demonstrasi, dan praktik langsung, yang mencakup proses karbonisasi, penggilingan, pencampuran perekat, pencetakan, hingga pengeringan briket. Berdasarkan hasil kegiatan, peserta mampu memahami dan mempraktikkan teknik pembuatan briket dari limbah cangkang kemiri secara mandiri. Cangkang kemiri yang sebelumnya hanya menjadi limbah, kini dapat diolah menjadi produk briket dengan nilai kalor tinggi setara batubara sehingga berpotensi mendukung ketahanan energi di tingkat pedesaan. Selain itu, kegiatan ini juga mendorong peningkatan kesadaran masyarakat terhadap pentingnya pemanfaatan energi terbarukan serta memberikan peluang peningkatan ekonomi melalui pemanfaatan limbah bernilai tambah. Dengan demikian, program ini diharapkan menjadi langkah awal dalam pengembangan inovasi energi berkelanjutan berbasis potensi lokal di wilayah pedesaan.

Abstract

The palm oil industry produces POME (Palm Oil Mill Effluent) liquid waste. POME is generally brownish, has an odor, and contains dissolved and suspended solids in the form of colloids and oil residue with a high Chemical Oxygen Demand (COD) content. Currently, the POME processing system still uses a conventional system known as the open pond system. This research aims to reduce the burden of organic materials related to removing COD levels, and color. It can solve the technical and operational obstacles of conventional processing systems. One of the extensive efforts to process POME is to develop Fenton-based photocatalytic technology, namely the Fenton-TiO2-UV method. Photocatalytic technology has several general processes involving semiconductor photocatalysts such as TiO2 and photon (UV) energy sources. In this study, the Fenton-TiO2-UV method was used with variations in the Fenton molar ratio of 1:100, 1:200, 1:300 (v/v), reaction times of 30, 60, and 90 minutes with TiO2 concentration 0.6% and uses 2 UV lamps (15 watts). This study achieved the maximum color degradation percentage at a Fenton molar ratio of 1:100 with a reaction time of 30 minutes, namely 95.28%. Meanwhile, the maximum COD degradation percentage was achieved at a Fenton molar ratio of 1:100 with a reaction time of 90 minutes, namely 98.88%.

Abstract

The Metaverse has emerged as a promising digital technology in education due to its ability to create immersive, interactive, and collaborative learning environments. This study aims to analyze the development of research on the integration of the Metaverse in education through a bibliometric approach. The research data were collected from the Dimensions database using the keywords “Metaverse” and “Education,” resulting in a total of 636 publications published between 2015 and 2025. Bibliometric analysis was conducted and visualized using VOSviewer software to identify publication trends, productive authors, leading contributing countries, and emerging research themes. The findings reveal a significant increase in the number of publications since 2021, with the highest publication output recorded in 2024. China, South Korea, and the United States were identified as the leading contributors to the field, while Hwang G.J. was recognized as one of the most prolific authors. Keyword network analysis indicates that the dominant research themes focus on the Metaverse, Virtual Reality, Augmented Reality, learning, and immersive learning experiences. Furthermore, emerging topics such as digital twins, artificial intelligence, and technology acceptance have begun to gain attention as potential directions for future research. These findings suggest that Metaverse research in education is developing in a multidisciplinary manner and holds significant potential to support the transformation of digital learning in the future.
