Abstract

Produksi tanaman kopi telah mendominasi menjadi produk utama perkebunan di wilayah kecamatan Gemawang. Permasalahan petani kopi adalah kurangnya pengetahuan tentang upaya pengembangan dari hasil kualitas dan produksi tanaman kopi. Pada kegiatan pengabdian ini bertujuan untuk melakukan pengabdian kepada masyarakat dalam mengatasi masalah tersebut dapat dilakukan melalui penyebaran informasi tertulis tentang praktik budidaya kopi yang baik dan informasi tentang teknik budidaya dan bibit yang digunakan, melalui perawatan tanaman dan rekayasa penyiraman ototmatis pada masa pembungaan. Pelaksanaan kegiatan pengabdian masyarakat dilaksanakan mulai bulan  Juni 2021 sampai tanggal 19 Nopember 2021. Sasaran dalam kegiatan ini adalah para petani kopi yang berlokasi di dusun Mandang, desa Sucen, kecamatan Gemawang, Kabupaten Temanggung. Hasil kegiatan yang telah terlaksana berupa kegiatan penyuluhan dan pendampingan tentang teknis budidaya kopi perawatan tanaman, diskusi tentang hama, penyuluhan pemasaran digital, penyuluhan materi organisasi kelembagaan, dan pemasang serta peragaan alat instalansi penyiraman otomatis. Kesimpulan kegiatan inia dalah kegiatan berjalan lancar petani kopi sangat antusias dan berpartisipasi aktif dalam kegiatan ini, sehingga hasil kegiatan menunjukkan adanya peningkatan ke arah yang positif setelah dilakukan kegiatan pengabdian kepada masyarakat ini.

Abstract

Palm oil mills used sand cyclones to reduce the sand content in sludge. High sand content (>5% in samples) and low efficiency caused pipe erosion, potential damage to decanter machines, increased maintenance costs, and reduced equipment lifespan. This study aimed to analyze the impact of flushing periodicity on the sand content in the sand cyclone outputs and to determine the optimal flushing periodicity. The experiment was conducted with six flushing time variations (P0 to P5) tested on sand cyclone 1 (SC1) and sand cyclone 2 (SC2). For SC1: P0 had a flushing time of 3.75 minutes, while P1, P2, and P3 were set at 4.25 minutes, and P4 and P5 at 4.75 minutes. For SC2, P0 had 7.50 minutes, P1 was 7.00 minutes, P2 was 7.50 minutes, P3 was 8 minutes, P4 was 7.50 minutes, and P5 was 8.00 minutes. Each treatment was replicated six times. The observed parameters included flushing water requirement, residual oil content, emulsion, moisture content, non-oil solids (NOS), and sand content. The results indicated that flushing periodicity significantly affected flushing water consumption, residual oil levels, emulsion formation, moisture content, NOS, and sand separation. The optimal flushing periodicity was able to reduce sand content in the sand cyclone overflow to 2.50%. To achieve maximum efficiency, a flushing frequency of 15 times per hour with a duration of 4.25 minutes is required for SC1, while for SC2 a flushing frequency of 8 times per hour with a duration of 7.50 minutes is required.
