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.

The village of Sungai Nanam, Lembah Gumanti, is an area in Solok Regency, West Sumatra, that produces significant organic waste from horticultural agriculture. If not managed properly, this waste can cause environmental and aesthetic issues. However, this waste can be converted into an eco-enzyme. An eco-enzyme is a liquid enzyme produced by fermenting organic waste. Eco-enzyme has many benefits, including being used as a liquid organic fertilizer, cleaner, and pest repellent. This community service aims to educate and train the community, especially the women farmers group, named Kelompok Wanita Tani (KWT) Rimbo Data Sejahtera, on converting organic waste into eco-enzymes. The program used three methods: socialization, demonstration, and mentoring. It has been proven to be an effective way to educate and train the community, particularly KWT Rimbo Data Sejahtera, on proper waste management. This program is a perfect fit for their needs and is very useful in reducing the impact of pollution.

Kegiatan penambangan memberikan nilai keuntungan ekonomi yang cukup besar bagi suatu negara, salah satunya tambang batu bara. Akan tetapi, dampak kerusakan lingkungan yang ditimbulkan juga relatif besar. Upaya revegetasi lahan dapat dicapai antara lain dengan penggunaan fungi mikoriza arbuskular (FMA). Penelitian ini bertujuan untuk memperoleh FMA indigen dari lahan bekas tambang batu bara di Kecamatan Talawi, Kota Sawahlunto untuk dikembangkan sebagai sumber inokulum, sehingga dapat diaplikasikan dalam upaya revegetasi lahan. Penelitian dilakukan dengan mengambil sampel tanah dari lahan bekas tambang batu bara sebanyak sepuluh titik yang dibedakan menjadi lima macam tipe kelerangan yaitu datar, landai, curam, agak curam, dan sangat curam. Hasil analisis tanah menunjukkan bahwa lahan bekas tambang batu bara tergolong tanah marginal dengan tingkat kesuburan rendah ditandai dengan dominasi fraksi pasir, pH rendah, kadar hara P, N, K, Ca, Mg, dan KTK yang rendah serta memiliki kandungan unsur logam Al dan Pb yang tinggi. Adapun dari lima kategori kelerengan ditemukan empat jenis spora FAM yaitu Glomus sp., Acaulospora sp., Gigaspora sp., dan Sclerocystis sp. Lereng datar memberikan jumlah spora tertinggi dibanding lereng lainnya. Glomus sp. memiliki kemampuan adaptasi yang lebih tinggi di semua tipe lereng dibandingkan jenis lain. Semakin tinggi pH dan kadar P dalam tanah, jumlah dan keanekaragaman spora akan semakin menurun. Sementara itu, semakin tinggi nilai KTK tanah, jumlah dan keanekaragaman spora akan semakin tinggi sampai batas optimal tertentu bergantung dari kemampuan adaptasi masing-masing spora FMA.

The Nagari Manggopoh is a central area for agricultural product corn, mainly corn for livestock, in Lubuk Basung District, Agam Regency, West Sumatra, Indonesia. The corn kernels produced are sold to animal feed processing factories. However, the corn stalk waste left after harvest is typically burned, leading to land biota damage and air pollution. This community service project aims to raise awareness and demonstrate the process of converting corn plant waste into compost. The project involved socializing, training, and practical demonstrations on composting corn crop waste. These activities have been conducted through counseling sessions, focus group discussions, and hands-on training from June to August 2022. Following the activities, an evaluation was conducted through discussions with the participants. The project's initial result was that ten stakeholders participated in the socialization of using corn crop waste for composting. Additionally, 15 Batang Piarau Jorong Sago farmer group members in Kenagarian Manggopoh have received training and successfully produced compost from corn stalk waste generated from animal feed crops.

Sugar-palm is an industrial crop whose almost all parts can be utilized, potentially improving the wealth of the society and the national economy. Despite its great potential, the development of sugar palm in Indonesia is still low, so it is necessary to do breeding through exploration and morphological characterization of germ plasm. In Talamau, West Pasaman, sugar palm still comes from wild forest, there is potential for superior individuals that have not been optimally utilized. The purpose of this study was to obtain information on the character and germ plasm of sugar palm in Talamau, West Pasaman. The research was conducted in May-July 2024 in Talamau, West Pasaman. The method used was survey with descriptive data presentation. The sampling technique used was purposive sampling. The plants used as samples are plants that meet the specified criteria, namely having entered the generative phase and tapped by farmers. The results showed that there were 14 accessions of sugar palm trees in Talamau. From the accessions, the characters that have wide diversity are plant height, stem circumference, number of leaflets, leaflet length, male bunch distance, fruit diameter, fruit weight, and sap yield. While narrow diversity in the character of midrib length, rachis length, stalk length, number of female flower bunches, seed diameter, number of seeds, and soluble sugar content. Then based on cluster analysis, the accessions of sugar palm in Talamau are divided into two clusters separated by the surface character of palm fiber with a level of 0-35% dissimilarity.

This study aimed to determine the interaction between the best AMF types and doses, the best AMF types, and the best doses on the growth of cocoa seedlings planted in after-lime mine soil. The experimental study was conducted from February to June 2025. This research was conducted at the Wire House, Faculty of Agriculture, Andalas University, Padang City, West Sumatra, in the Seed Science and Technology Laboratory, Faculty of Agriculture, Andalas University. Root colonization observations were conducted at the Plant Physiology Laboratory, Faculty of Agriculture, Andalas University, Padang. The study used a factorial completely randomized design (CRD) consisting of two factors. The first factor was the type of AMF, with three levels: Glomus sp., Gigaspora sp., and Acaulospora sp. The second factor was the AMF dosage, with four levels: 0 g/seedling, 10 g/seedling, 20 g/seedling, and 30 g/seedling. Data were analyzed statistically using the F-test at a 5% significance level. If the calculated F-test was greater than the table F-test, the analysis was continued with Duncan's New Multiple Range Test (DNMRT) at a 5% significance level. The results of this study indicate that there was no interaction between the type and dosage of AMF on the growth of cocoa seedlings planted in ex-lime mining soil. The Glomus sp. AMF was the best AMF for enhancing the growth of cocoa seedlings planted in ex-lime mining soil. Meanwhile, the AMF dosage of 30 g/seedling was the best for enhancing the growth of cocoa seedlings planted in ex-lime mining soil.
