Abstract

Composites are one of the material engineering technologies developed today because composites can combine several material properties that differ in characteristics into new properties by the planned design. The purpose of this study was to determine the mechanical properties of the influence of the combined arrangement of lamina angle variations and the composition of fiber and matrix mixtures. This study uses polyester resin, catalyst, and sisal fiber as materials in the manufacture of composite materials. In specimen manufacturing refers to ASTM D 638-02 type 3 test standard for tensile tests. The tensile test results of sisal fiber lamina composite materials assuming a composition ratio of 5% fiber and 95% resin produce maximum tensile stress of m = 16.9854 N/mm2 and a maximum strain of ɛ = 4.5232% while assuming a composition ratio of 15% fiber 85% resin produces maximum tensile stress of sm = 40.1422 N/mm2 and maximum strain of ɛ = 8.9744 %, Based on the test results, the addition of fiber mixture composition increases the tensile strength and toughness of the material. The composition of 5% fiber 95% and 15% fiber 85% resin (15S-85R)produces a maximum tensile stress of sm =  45.1823 N/mm2 and a maximum strain of ɛ = 9.6849 % with a maximum load Fm = 10902.4996 N. The more fiber contained in the sisal fiber lamina composite material, the higher the tensile stress produced, this shows the tension is directly proportional to the number of fibers contained in the composite.

Abstract

Implementasi kebun percontohan sebagai sarana edukatif terkait pertanian organik di Lembang Toyasa Akung, Toraja Utara. Kebun percontohan ditujukan untuk mendemonstrasikan praktik pertanian organik yang berkelanjutan dan sebagai pusat pembelajaran bagi masyarakat setempat. Metode inovatif yang diintegrasikan dalam kebun percontohan adalah sistem terbas mekanis, dimana mesin rumput digunakan untuk mengelola biomassa dan menjaga kesuburan tanah. Metode terbas mekanis dipilih karena efektivitasnya dalam mengendalikan pertumbuhan rumput dan sebagai alternatif mekanis yang ramah lingkungan dalam mengurangi penggunaan herbisida. Penerapan sistem ini diharapkan dapat mendorong kesuburan tanah secara alami serta mempertahankan kesehatan ekosistem pertanian dengan memanfaatkan hasil terbasan sebagai mulsa organik, yang mendukung siklus nutrisi tanah. Pengabdian masyarakat yang berfokus pada penyiapan lahan dan pendidikan tentang pertanian organik di lembang ini telah menghasilkan kemajuan dalam pengetahuan dan keterampilan bertani organik di kalangan masyarakat. Dengan kegiatan yang dilaksanakan pada 31 Agustus 2023, keberhasilan kebun percontohan ini menjadi titik awal penting dalam praktek pertanian berkelanjutan di TorajaUtara, dan diharapkan dapat diadopsi lebih luas.

Abstract

Organic farming is increasingly in demand because it prioritizes sustainability and environmentally friendly principles. Liquid organic fertilizer made from banana tubers and leri water is an alternative that is environmentally friendly and easy to produce. However, knowledge and skills in making liquid organic fertilizer still need to be improved among the community, especially in areas such as Lembang Rantedada. This study was carried out through direct assistance and training activities for the community in Lembang Rantedada with a practical and participatory approach, involving the community in every stage of fertilizer production, from raw material preparation to the fermentation and storage process. The result of this mentoring activity is an increase in community knowledge and skills in making liquid organic fertilizer. Communities can use locally available banana stems and water to produce organic fertilizer that is beneficial for their agriculture. Apart from that, awareness is also created about the importance of using organic fertilizer in supporting sustainable agriculture and environmental preservation. Assistance in making liquid organic fertilizer from banana stems and leri water to the community in Lembang Rantedada is an effective step in increasing the independence and sustainability of local agriculture. By increasing knowledge and skills, communities can utilize local resources more optimally and support environmentally friendly agricultural practices
