Abstract

This research was motivated by the abundance of biomass plantations in Indonesia. Accumulated biomass waste will cause environmental problems. Biomass processing can resolve this issue, by producing functionally and economically valuable products. The purpose of this research was to increase the value of biomass by processing it as liquid smoke through pyrolysis and then proceeding to the purification stage. The purification method applied in this research was a combination of distillation and adsorption processes using natural zeolite. The variables of this research were: two types of biomass, namely coconut shells and palm kernel shells, and liquid smoke grade variations. The analysis parameters were: pH, viscosity, density, acid content, and phenol analysis as well as GC-MS. The characteristics analysis results showed that all liquid smoke samples met the Japanese liquid smoke standard. Based on pH, acid, and phenol analysis, the liquid smoke from the coconut shells sample had better quality compared to the liquid smoke from palm kernel shells, namely with pH 2.36, acid content 0.26 mg/mL, and phenol 2,368.75 ppm. The GC-MS test results indicated that grade-1 liquid smoke from both samples contained antibacterial compounds, such as phosphonic acid, formic acid, and carbamic acid, which have the potential to inhibit bacterial growth.

Abstract

Ampas kopi merupakan residu dari proses penyeduhan kopi yang dapat menjadi limbah padat jika tidak dimanfaatkan dengan baik. Penumpukan ampas kopi dapat mencemari lingkungan, terutama di daerah yang memiliki banyak kedai kopi, seperti di Kabupaten Ogan Ilir. Oleh karena itu, diperlukan solusi untuk mengelola limbah ini menjadi produk yang bernilai. Pengabdian ini bertujuan untuk memberikan pembinaan kepada siswa/i SMK Negeri 1 Tanjung Batu mengenai pemanfaatan ampas kopi menjadi sabun, guna mengurangi limbah ampas kopi di Kabupaten Ogan Ilir dan memberikan pengetahuan tentang cara membuat produk bernilai tambah dari limbah kopi. Metode yang digunakan dalam pengabdian ini adalah penyuluhan dan demonstrasi. Proses pembuatan sabun dimulai dari preparasi bahan baku, saponifikasi, pencetakan, framing, dan pengujian. Kegiatan ini dilakukan di SMK Negeri 1 Tanjung Batu dengan melibatkan siswa/i dan guru dalam proses demonstrasi.Pelaksanaan pengabdian menunjukkan respon positif dari peserta. Dari 52 peserta, 47 orang menyatakan bahwa mereka telah memahami dan mengerti setiap langkah dalam pembuatan sabun dari ampas kopi. Berdasarkan kuesioner yang diisi, 90% peserta mengerti dan memberikan respon positif terhadap materi yang disampaikan.Kegiatan pengabdian ini berhasil meningkatkan pemahaman siswa/i SMK Negeri 1 Tanjung Batu tentang cara mengolah limbah ampas kopi menjadi produk yang bermanfaat, yaitu sabun. Melalui pelatihan ini, peserta tidak hanya memperoleh pengetahuan baru, tetapi juga dapat memanfaatkan ampas kopi yang sebelumnya dibuang menjadi produk bernilai yang dapat meningkatkan kesadaran tentang pentingnya pengelolaan limbah di lingkungan sekitar.

Abstract

Consumption of fuel energy continues to increase every year. Still, the fuel used today is almost entirely derived from fossil materials that are toxic to the environment and not renewable, so they need renewability to be guaranteed. One solution to this problem is ethyl ester based on catfish (Pangasius Hypothalamus) tallow waste. The catfish fish tallow is extracted first and then in a liquid phase and then reacted with the help of a KOH catalyst (1%; 1.5%; 2%) by electrolysis method using copper electrodes with a transesterification reaction. The research was conducted on the ratio of raw materials to ethanol of 1:5, 1:6, and 1:7 with a power supply voltage of 20V. It can be seen from the research results that the mole ratio of raw material and ethanol at 1:6 produces ethyl esters with a tendency to be of better quality. The best ethyl ester yield was obtained at a ratio of 1:6 raw material and 1.5% catalyst amount, and the resulting yield was 92.4058%.
