Abstract

Peningkatan permintaan global terhadap energi telah meningkatkan penggunaan bahan bakar fosil, yang tidak terbarukan dan berdampak negatif pada lingkungan. Di Indonesia, limbah tempurung kelapa sering diabaikan padahal memiliki potensi menjadi produk yang lebih bernilai dan bermanfaat yaitu diolah menjadi briket sebagai bahan bakar alternatif yang lebih ramah lingkungan dan juga dapat membuka peluang ekonomi. Pengabdian masyarakat di Kelurahan Noborejo, Kecamatan Argomulyo, Kota Salatiga, bertujuan untuk memberikan pelatihan kepada masyarakat setempat tentang cara mengolah limbah tempurung kelapa menjadi briket. Kegiatan ini menggunakan metode partisipatif dengan tiga tahap: persiapan, sosialisasi, dan pelatihan. Peserta, terutama ibu-ibu PKK, dilatih untuk memproduksi briket dengan alat dan bahan sederhana seperti tepung tapioka sebagai perekat alami. Hasilnya menunjukkan bahwa masyarakat dapat memproduksi briket secara mandiri, meskipun terdapat tantangan seperti keterbatasan peralatan. Program ini berhasil meningkatkan keterampilan masyarakat, membuka peluang ekonomi baru, mengurangi polusi lingkungan, dan mendukung upaya global untuk mengurangi emisi karbon. Pengelolaan limbah kelapa yang lebih baik memberikan manfaat ekonomi dan lingkungan yang signifikan bagi masyarakat setempat.

In Indonesia, coconut shell waste is often overlooked, although it has the potential to be converted into a more valuable and useful product, namely briquettes, as a more environmentally friendly alternative fuel that can also open up economic opportunities. A community service project in Kelurahan Noborejo, Kecamatan Argomulyo, Kota Salatiga, aims to provide training to local residents on how to process coconut shell waste into briquettes. This activity uses a participatory method with three stages: preparation, socialization, and training. Participants, especially members of the local women's organization (PKK), are trained to produce briquettes using simple tools and materials, such as tapioca flour as a natural adhesive. The results show that the community can produce briquettes independently, although there are challenges such as limited equipment. This program successfully enhances community skills, opens up new economic opportunities, reduces environmental pollution, and supports global efforts to reduce carbon emissions. Better management of coconut waste provides significant economic and environmental benefits for the local community. Keywords: bioenergy, briquettes, waste, shell, coconut

Abstract

This research examines the influence of first language (L1) interference on the speaking ability of Indonesian EFL learners at the higher education level, focusing on English Education students. Using a mixed method approach, data were gathered through questionnaires (closed-ended and open-ended) and semi-structured interviews with intermediate-level learners in English. The findings identify two dominant forms of L1 interference: grammatical and phonological. Grammatical interference involves the transfer of Indonesian sentence structures and tense usage into English, while phonological interference appears in the mispronunciation of unfamiliar English sounds. Four key factors contribute to this interference: linguistic background, proficiency level, psychological barriers, and learning strategies. The interference significantly hinders both accuracy and fluency, often due to mental translation habits, lack of confidence, and overreliance on grammar-based instruction. The study concludes that L1 interference is a complex issue requiring communicative, confidence-oriented teaching methods and greater exposure to authentic English use. This insight offers practical implications such as the implementation of short lessons that give EFL students space to study or practice without pressure so that they can improve their English as a foreign language skill.
