Abstract

Background: Salah satu faktor penentu kualitas dan produktivitas kopi yang dihasilkan adalah kualitas lahan kebun kopi. Diharapkan para petani dapat menjaga kualitas tanaman dengan perawatan melalui dukungan peningkatan unsur hara tanah pada lahan dengan bantuan pupuk kompos. Kegiatan ini dapat dilaksanakan dengan dukungan penuh dari kepala desa Kenine Bener Meriah dengan jumlah peserta sebanyak 26 orang masyarakat desa Kenine. Metode: Pada tahap pertama dilakukan pembuatan alat biopori dan alat sensor pH berbasis IoT yang kemudian di praktekkan langsung pada salah satu lahan kenun kopi masyarakat desa Kenine. Tim penyuluhan juga mengarahkan masyarakat untuk terjun langsung ke lapangan untuk melakukan simulasi penggunaan alat biopori ini. Selanjutnya tim memberikan pengarahan dan manfaat penggunaan alat biopori di bandingkan dengan kegiatan yang biasa dilakukan masyarakat untuk menyuburkan kebun mereka. Selanjutnya pada tahap evaluasi tim juga memantau hasil yang di dapat setelah penerapan biopori serta memantau pemakaian sensor pada kebun warga. Hasil: Peningkatan pada tumbuhan kopi yang dipakai alat biopori dan diharapkan produktivitas kopi juga meningkat seiring dengan pertumbuhan pokok kopi tersebut. Kesimpulan: Penggunaan pipa biopori untuk pembusukan limbah kulit kopi bermanfaat untuk menggemburkan tanah, menjadi pupuk kompos dan dapat menambah volume penyerapan air hujan.

Abstract

Geomembranes are thin geosynthetic materials composed of polymeric layers that function as barriers in direct contact with soil. The properties of HDPE geomembranes suitable for application as vannamei shrimp (Litopenaeus vannamei) aquaculture. HDPE geomembranes applied in vannamei shrimp aquaculture are subjected to thermal loads (UV radiation), oxidative agents, and mechanical force such as interfacial friction and tensile loading in surface wear.  This study aims to improve the mechanical properties of the material by incorporating natural fibers as reinforcement into HDPE–ramie fiber biocomposite. The process of making HDPE–ramie fiber biocomposite uses an single screw extruder with a temperature of 170 oC, a rotation of 20 rpm with a ratio of HDPE waste and ramie fiber of 97.5:2.5, 95:5, and 92.5:7.5. The results of tensile and impact tests show the highest strength and toughness are shown in the HDPE sample and ramie fiber 92.5:7.5 with a value of 5.23 MPa and 96.17 kJ/m2. The highest material ductility was demonstrated in the HDPE and ramie fiber composite 97.5:2.5 with a value of 1.32%. In addition, the highest stiffness was demonstrated in the HDPE and ramie fiber composite 95:5 with a value of 845.40 MPa. The results of the morphological investigation showed that the bond between the matrix and filler was partially formed and the smallest fiber diameter was 4 µm.Keywords: HDPE, Ramie, Composite, Geomembrane, Vanamei
