Abstract

Cocoa is a plantation commodity that is essential to the Indonesian economy. There are still many problems in cocoa cultivation found in the field, such as using poor-quality seedlings. One of the ways to do this is by taking preventive action by providing immunity induction from the seedling stage. Immunity induction can be done by utilizing Rhizobacteria, arbuscular mycorrhizal fungi, Entomopathogenic fungi, and vegetable pesticides. The Faculty of Agriculture of Universitas Andalas collaborated with the entrepreneurs through a Ministry of Education and Culture program, Matching Fund 2022, to make an innovation, namely the Teaching Farm for superior cocoa nurseries. This activity aims to socialize the cocoa nursery teaching farm in the hope of helping farmers prepare high-quality and sustainable cocoa seeds. This community service activity has been carried out at the Padang City Agriculture Office. The conclusions of this activity include: a) The community service program made by the Teaching Farm Team of Universitas Andalas is by the needs of the farmer group; the farmer group is satisfied and feels this service activity was helpful for the development of the Cocoa farmer group in the future, b) enrichment of understanding of farmer group members regarding biofertilizers and vegetable pesticides.

Abstract

The excessive and improper use of synthetic pesticides triggers ecosystem damage. The negative impacts of pesticide use can result in pest resistance, resurgence, the death of natural enemies, residue left on crop yields, and environmental pollution. Aside from the negative impacts on the environment, the use of synthetic pesticides burdens farmers due to their relatively high cost. Botanical pesticides become an alternative for controlling plant pests (Pests). Thus, a socialization on making botanical pesticides was conducted in Cubadak Air Village, North Pariaman Subdistrict, Pariaman City. The objective of creating botanical pesticides was to reduce the use of synthetic pesticides, decrease control costs, and maintain agricultural ecosystems. The botanical pesticide-making activity was carried out on July 19-20, 2023, in Cubadak Air Village, North Pariaman Subdistrict, Pariaman City. The method used was a direct demonstration of botanical pesticide production to farmer groups and the community in Cubadak Air Village. The results obtained after empowering the community in making botanical pesticides were that farmers could directly produce these pesticides, thereby aiding in the farmers' economy by reducing pesticide purchasing costs, utilizing wild plants like weeds to be used as botanical pesticides. The training on making botanical pesticides proceeded smoothly, and participants showed enthusiasm for the presented material. The use of environmentally friendly botanical pesticides, utilizing available natural resources, helps to maintain ecosystem balance.

Abstract

Meloidogyne spp. is responsible of root swelling, one of the primary disease in tomato plants. Controlling this nematode is challenging due to its wide host range. The use of synthetic nematicides harms the environment; therefore, alternative controls, such as biological methods, are necessary. Among the biological agents, one group includes endophytic bacteria that reside in plant tissues and do not cause harm to plants. These bacteria enhance plant resistance to pests and pathogens while promoting plant growth. The study aimed to acquire endophytes, Bacillus spp. strains capable of controlling Meloidogyne sp. while stimulating the growth of tomato plants. The research employed a completely randomized design (CRD) comprising seven treatments and five replications. The treatments consisted of B. cereus strain SNE 2.2, TLE 2.3 and TLE 1.1, B. pseudomycoides strain EPL 1.1.3, B. toyonensis strain EPL 1.1.4, positive control (without the introduction of Bacillus spp. and inoculation with Meloidogyne sp.) and negative control (without Bacillus spp. and without Meloidogyne sp.). Bacillus spp. endophyites were introduced in two stages: into the seeds and into the roots of tomato seedlings for 15 min. The observed variables were the development of Meloidogyne sp., endophytic colonization of Bacillus spp., and plant growth. The results demonstrated that all Bacillus spp. were effective in controlling Meloidogyne sp. and enhancing the growth of tomato plants. The best isolate in controlling Meloidogyne sp. and increasing the growth of tomato plants was B. cereus strain SNE2.2.

Abstract. Nagari Sungai Talang is one of the villages in Payakumbuh District, Lima Puluh Kota Regency which seeks to cultivate ginger plants. Ginger (Zingiber officinale Rosc.) is a spice plant native to Indonesia. Ginger has long been cultivated and consumed by the community. The part of the ginger plant that is consumed is the rhizome. One of the problems in ginger cultivation in Indonesia is the low productivity and quality of ginger. Ginger seeds in the form of rhizomes must be processed and stored as well as possible so that their quality can be maintained longer by inhibiting the rate of seedling decline. The purpose of this service activity is to invite farmers, especially the Innovation farmer group in order to sort ginger seeds with government assistance (selection of good and healthy ginger seeds) so that the production of ginger plants can increase even better than the previous cultivation. The method of implementing this service is Community Education. Community education in this activity by carrying out socialization and counseling aimed at increasing knowledge and understanding of the community, especially ginger farmers about good and healthy ginger to be used as seeds for the implementation of further cultivation in the field. The results obtained from this empowerment activity are that the farmer group understands the type of rhizome that is chosen to be used as the next seed. The selection of the type of rhizome can be seen from the number of good buds, uniform shoot height, age of rhizome, and appearance of ginger rhizome. Abstrak. Nagari Sungai Talang merupakan salah satu nagari di Kecamatan Payakumbuh, Kabupaten Lima Puluh Kota yang mengupayakan budidaya tanaman jahe. Jahe (Zingiber officinale Rosc.) merupakan salah satu tanaman rempah asli Indonesia. Jahe sudah lama dibudidayakan dan dikonsumsi oleh masyarakat. Bagian tanaman jahe yang dikonsumsi adalah bagian rimpangnya. Salah satu permasalahan dalam budidaya jahe di Indonesia adalah masih rendahnya produktivitas dan mutu jahe. Bibit jahe berupa rimpang harus diproses dan disimpan sebaik mungkin agar mutunya dapat dipertahankan lebih lama dengan menghambat laju kemunduran bibit. Tujuan kegiatan pengabdian ini yaitu untuk mengajak para petani khususnya kelompok tani Inovasi dalam rangka penyortiran bibit jahe bantuan pemerintah (pemilihan bibit jahe yang baik dan sehat) sehingga hasil produksi dari tanaman jahe dapat meningkat lebih baik lagi dari budidaya sebelumnya. Metode pelaksanaan pengabdian ini adalah Pendidikan Masyarakat. Pendidikan masyarakat dalam kegiatan ini dengan melaksanakan sosialisasi dan penyuluhan yang bertujuan meningkatkan pengetahuan dan pemahaman masyarakat khususnya petani jahe tentang jahe yang bagus dan sehat yang baik untuk dijadikan sebagai bibit untuk pelaksanaan budidaya selanjutnya dilapangan. Hasil yang diperoleh dari kegiatan pemberdayaan ini adalah kelompok tani memahami jenis rimpang yang dipilih untuk dijadikan bakal benih selanjutnya. Pemilihan jenis rimpang dapat dilihat dari jumlah bakal mata tunas yang baik, tinggi tunas yang seragam, umur rimpang, serta penampilan rimpang jahe.
