Abstract

Plastic waste is an inseparable part of human life. People's habit of burning accumulated plastic waste can release heavy metal content in plastic and toxic chemicals such as dioxins which can interfere with the respiratory process. There is another way to reduce plastic waste, namely by melting plastic waste into paving blocks. The process of melting plastic waste is carried out in a melting furnace. The purpose of this study is to analyze the heat transfer that occurs in the smelting furnace. The method used in this research is heat transfer analysis using FEM analysis and heat transfer analysis through experimental studies. The results obtained in the FEM analysis, the heat generated by the smelting furnace ranges from 212-300 ⁰C. While the heat generated in the measurement process is 280 ⁰C. Analysis of heat transfer that occurs in the smelting furnace obtained a figure of 1.95 Watt. The value of the wasted heat from the smelting furnace is 6.77 W. This means that the wasted heat is greater than the heat generated from the smelting furnace, this will result in a waste of energy. To overcome wasted heat, it is recommended to add insulating material to the furnace around smelting.

Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan kemampuan literasi digital dan keterampilan menulis takarir (caption) promosi yang menarik, etis, dan persuasif bagi pelaku UMKM Comring di Dusun Cilulumpang Desa Kertayasa kecamatan Kabupaten Ciamis. Permasalahan utama yang dihadapi peserta adalah kurangnya pemahaman terhadap konsep takarir sebagai media komunikasi pemasaran digital yang efektif. Pelatihan dilaksanakan pada 1 November 2025 oleh tim dosen Universitas Galuh Ciamis menggunakan pendekatan andragogi dan konstruktivisme sosial melalui metode ceramah interaktif, diskusi, dan praktik langsung. Evaluasi dilakukan dengan membandingkan hasil pre-test dan post-test terhadap sepuluh indikator pemahaman dan keterampilan menulis takarir. Hasil pelatihan menunjukkan adanya peningkatan signifikan pada seluruh aspek kompetensi peserta, dengan rata-rata nilai pre-test 2,48 meningkat menjadi 4,46 pada post-test, atau terjadi kenaikan sebesar 79%. Peningkatan tertinggi terdapat pada aspek pemahaman pengertian takarir dan kemampuan menyesuaikan teks dengan produk promosi (masing-masing +2,6 poin). Selain peningkatan pengetahuan, peserta juga menunjukkan kemampuan menyusun takarir dengan struktur lengkap (hook–deskripsi–CTA), menggunakan diksi persuasif, serta menerapkan prinsip etika dan kejujuran dalam penulisan teks promosi.
