Abstract

The control of Colletotrichum gloeosporioides, the causal agent of anthracnose in chili, is typically achieved through synthetic fungicides, which pose risks to both the environment and consumers. As a safer alternative, microbial-derived biopesticides offer an environmentally friendly solution. This study aimed to evaluate the potential of secondary metabolites produced by Trichoderma viride T1sk, extracted using organic solvents with different polarities (ethyl acetate and butanol), to inhibit the growth of C. gloeosporioides in vitro. A Completely Randomized Design (CRD) was used, comprising three treatments with six replications, each consisting of two petri dish units. The treatments included: (A) ethyl acetate extract, (B) butanol extract, and (C) a control. The media poisoning method was employed to assess the antifungal activity of the extracts. Key parameters observed were colony area, conidial count, conidial germination rate, and propagule density of C. gloeosporioides. The results demonstrated that both ethyl acetate and butanol effectively extracted antifungal secondary metabolites from T. viride T1sk. In general, these metabolites significantly suppressed the growth of C. gloeosporioides. Among the solvents tested, butanol exhibited the highest efficacy in extracting antifungal compounds and consistently achieving the strongest inhibition across all observed variables.

Abstract

Pembukaan lahan merupakan kegiatan membuka atau membersihkan lahan yang awalnya hutan atau ditanami pepohonan menjadi lahan yang akan digunakan untuk berbagai kegiatan. Pembukaan lahan dilakukan oleh petani untuk membuka lahan yang akan dipakai untuk lahan pertanian. Pembukaan lahan penting bagi sebagian orang apalagi yang bekerja sebagai pekebun ataupun petani, banyaknya masyarakat yang bekerja sebagai pekebun menimbulkan tumbuh pesatnya pemanfaatan lahan. Penggunaan lahan tersebut jarang sekali memperhatikan kondisi lahan untuk diolah, banyak juga kondisi lahan yang mempunyai keterbatasan fisik maupun kimia namun masih saja diolah dan ini mengakibatkan rusaknya lahan, salah satu contohnya adalah kebakaran lahan. Masyarakat di Nagari Sungai Dareh dalam pengelolaan SDA (Sumber Daya Alam) masih banyak diakukan dengan menggunakan media api, salah satu kegiatan masyarakat yang berhubungan dengan penggunaan media api antara lain: pembukaan lahan untuk persiapan sawah/kebun/ternak, pencarian lokasi ikan di rawa-rawa dengan cara membakar semak-semak yang menutupi permukaan air, pemberantasan hama tikus/babi, dan sebagainya. Penyiapan lahan tanpa bakar adalah teknik pembuatan rintisan dan pembagian petak tanaman dengan menggunakan alat. Keuntungan dari teknik mengolah lahan tanpa bakar yaitu dalam aplikasinya tidak terlalu tergantung pada kondisi cuaca, kecuali kondisi yang terlalu basah karena dapat menghambat mobilitas alat berat. Selain itu, kelebihan utama teknik ini adalah jauh lebih ramah lingkungan dibandingkan dengan teknik pembakaran. Selain manfaat lingkungan dan agronomis, pembukaan lahan tanpa bakar juga memberikan nilai tambah ekonomis.

Abstract

The Tunas Harapan Women Farmers Group, Limau Manis Village, Pauh District, Padang City is one of the farmer groups that has various problems such as drought, high amount of unused land and far access. The main crop planted during the rainy season is lowland rice, but most of the land becomes idle land during the dry season. Another problem that is often faced during the implementation of cultivation is the problem of pests and diseases which are the cause of low production yields. In terms of fertilization, farmers in this location still use artificial fertilizers (chemical fertilizers) and in terms of pest control, they still use chemical pesticides. One of the main components of the IPM program that can be used to control plant pests and diseases is the use of biological agents. The purpose of this community service activity is to increase public knowledge about pests and diseases that often attack rice plants, resulting in decreased yields and crop failure. The method used is the method of socialization, counseling and direct discussion with farmer groups about pests and diseases that often attack rice plants in the field. The results obtained from this empowerment activity are that the Tunas Harapan KWT farmer group understands various plant-disturbing organisms that attack rice plants, the community knows better how to control it properly, so that it can increase production better

Abstract

Sugar palm is a plant that has high economic potential, but its cultivation in Indonesia is still lacking in attention. The demand for palm sugar will continue to increase, so it is important to develop the cultivation of this plant with environmentally friendly methods. Through the Community Partnership Helping Businesses Grow (PKM MUB) program, a community service team consisting of academics and students from Andalas University collaborated with the Bukik Kandang Forest Farmers Group. Identification of problems includes slow growth of sugar palm plants due to lack of proper maintenance and fertilization. Therefore, this community service proposes the use of organic fertilizers, such as buffalo manure, palm oil mill liquid waste, and solid decanters, to increase plant growth. The methods used include socialization, training, and assistance to farmers in implementing efficient cultivation technology by observing all activities in the field that include aspects of sugar palm cultivation. The stages carried out in this activity include: Location survey, demonstration socialization, land clearing, preparation of organic materials, application of organic fertilizers, preparation of seeds, planting, and maintenance. The target output of this community service is an accredited scientific article and increased productivity and farmer welfare. These expected steps can improve food security and contribute to local economic development as well as environmental preservation and the application of sugar palm cultivation technology by utilizing several types of organic fertilizers, which have been proven to improve plant growth and farmer welfare in Nagari Sungai Dareh. Through socialization, training, and mentoring methods, farmers gain a better understanding of environmentally friendly plant maintenance techniques.
