Oil palm plants are the belle of the community in the Dharmasraya Regency today. One of the causes of the low productivity of community plantations is caused by the production technology that is applied relatively simple, starting from seeding to harvesting. With the application of appropriate cultivation technology, it will be directed to increase palm oil production. The activity objectives are to 1) increase the understanding and knowledge of the Nagari Silago community about oil palm production technology, 2) improve the community's knowledge and skills in processing agricultural waste to be more useful 3) encourage the enthusiasm of farmers so that they can better utilize Nagari Silago's agricultural potential. This community service activity was carried out in Nagari Silago District IX Koto Dharmasraya Regency on 26-27 October 2019. This community service activity was carried out using the lecture, discussion method. The number of students involved numbered 150 people. Previously, the community service participants only followed the coconut cultivation technique, which was carried out by the farmers before, even though the cultivation technique was not correct. The Nagari Silago community is very enthusiastic about welcoming and discussing about the technology of oil palm cultivation. Many people ask questions, and good discussions are starting from the origin of seedlings and oil palm nursery techniques, land clearing, fertilizing, castration, pest control, and diseases of oil palm plants. Farmers can consider the concept of 5 T, which is the right way, the proper dosage, the right time, the right type and the right quality that is important in providing that which is not suitable enough for vegetative and generative growth of oil palm.

Nagari Sungai Dareh, Pulau Punjung District, Dharmasraya Regency is an area located on the banks of the Batang Hari River. Rivers must be protected and conserved, and their functions and benefits must be improved for the health and sustainability of the ecosystem. Planting sugar palm on the river banks is one way that can be done to preserve the river. Besides being useful for conservation, sugar palm also has a high economic value. This activity aims to empower the community by 1) Conservation activities on the banks of the Batang Hari river, and 2) Introduction of sugar palm plants and increasing community knowledge and skills in sugar palm cultivation. This activity was carried out in Jorong Sungai Kilangan Nagari Sungai Dareh, Dharmasraya Regency, with lectures, discussions, and demonstrations of planting sugar palm on the banks of the river. The number of students involved was five people. The people of Nagari Sungai Dareh are very enthusiastic about listening and discussing sugar palm cultivation and the importance of river conservation. Most of the participants are very interested and will immediately plant sugar palm on their land, but some are still learning more. As a form of our hope that the planting of sugar palm on the river banks can be successful, we assist ± 200 sugar palm seeds for the people of Nagari Sungai Dareh. Community empowerment through sugar palm cultivation has been able to increase community knowledge and skills about the importance of maintaining river sustainability and the prospects and challenges of sugar palm cultivation.

The present study was conducted in Tebing Tinggi Village, Pulau Punjung Sub-district, Dharmasraya District was motivated by a desire to exploit land resources, especially open access land that was formerly a gold mine by cultivating oil palm plants. The objectives of this study were to determine the characteristics of soil chemical properties, the soil fertility level, and the level of mercury (Hg) contamination in former gold mining land by compared with the soil chemical fertility of oil palm plantations. The research method was a survey by purposive sampling. The Soil sampling for analysis of soil chemical properties was carried out by drilling of 0-40 cm deep with 12 sample points divided into 4 locations, where 3 locations in the former gold mine area that were grouped into three segments, namely segments 1, 2 and 3 and one location was in oil palm land. The parameters of soil chemical properties observed were pH, Al-dd, C-organic, C / N Ratio, N, P, K and Hg (Mercury). The results of this research, shows that the characteristics of soil chemical properties in the former gold mining area have decreased the level of soil fertility, characterized by the very low pH value and C-organic content, so that the nutrients contained in the land are very limited when compared to the soil fertility in oil palm land. This is indicated by the fact that the oil palm land has a high C-organic content and a moderate level of N-total content. The utilization of the land resources of the former gold mine, it is necessary to do land improvementsin terms of soil physically, chemically and biologically.

Cameroon and Angola, accession palms oil, were two plants with different flower architectures such as bunch size, bunch length, number of spikelets and flowers, and volatile compounds produced. The difference in flower characteristics was thought to affect the presence of flower-visiting insects in the two palm oil accessions. The study aimed to determine the insects that visit Cameroon and Angola palm oil flower accessions. Insects that visit flowers were collected directly, using yellow pan traps, swing nets, and aspirators. Collected flower-visiting insects were identified as species. Diversity and evenness were calculated using the Shannon diversity index and the Simpsons’ evenness. The total number of flower-visiting insects collected was 2039 individuals. In the Angola accession, 150 individuals were found consisting of 5 orders, 10 families, and 14 species. Insects that visited Cameroon’s accession of palm oil flowers were 1889 individuals consisting of 8 orders, 16 families, and 22 species. Angola accessions’ diversity and evenness index were higher than Cameroon’s, namely 1.50; 1.14 and 1.14; 0.52. Flower-visiting insects that act as pollinators were Elaeidobius kamerunicus, Pyroderces Sp, and Thrips hawaiiensis.

Organic matter has a very important role in determining the level of soil fertility, especially in marginal soils such as Oxisol which is widespread in Indonesia. Organic matter that is commonly used requires large amounts and has the ability to react relatively slowly in the soil. Therefore, it is necessary to make efforts to obtain organic material that reacts quickly in the soil, such as humic material extracted from lignite. In this study, cocoa (Theobroma cacao) was used as an indicator plant. Cocoa is one of the plantation commodities that has a fairly important role in the national economy, especially as foreign exchange for the country and has a relatively stable price. This research was conducted in the form of a pot experiment using a 2 x 4 x 4 factorial design with 3 replications in a divided plot design, so that 32 treatments and 96 experimental units were obtained. From the research results obtained data that the addition of humic materials and compost up to a dose of 4% C-organic combined with artificial fertilizers can increase the availability of nutrients for cocoa seedlings in Oxisol. The best dose of each treatment was the addition of humic material at a dose of 4% C-organic combined with artificial fertilizer 50% of the recommendation and the addition of compost at a dose of 4% C-organic combined with artificial fertilizer 50% of the recommendation. The addition of organic matter can reduce the use of artificial fertilizers up to 50% of the recommendation. The addition of humic materials from unproductive coal can increase the availability of nutrients in Oxisol. Unproductive coal has the potential to increase Oxisol soil fertility.

Dharmasraya merupakan salah satu kabupaten di Sumatera Barat yang potensial untuk pengembangan komoditi kopi, sejak mulai dikembangkan tahun 2002 produksi kopi di Kabupaten Dharmasaraya menurun. Hal ini disebabkan budidaya kopi yang dilakukan selama ini tidak intensif. Rendahnya perhatian petani selama budidaya kopi juga dipicu pertumbuhan kopi yang ditanam tidak optimal. Bibit yang baik merupakan modal keberhasilan pertumbuhan tanaman di lapangan karena mampu berproduksi secara optimal. Perbanyakan tanaman kopi dapat dilakukan secara generatif dan vegetatif. Perbanyakan secara generatif menggunakan biji. Kendala dalam perbanyakan kopi secara generatif adalah biji kopi memerlukan waktu cukup lama untuk berkecambah.. Penelitian ini dilakukan di Laboratorium Teknologi Benih Fakultas Pertanian Universitas Andalas Kampus 3 Dharmasraya dari bulan Juli sampai dengan September 2022. Parameter yang diamati adalah bobot benih awal (g), bobot benih setelah perlakuan (g), kadar air benih awal (%), kadar air benih setelah perlakuan (%). Hasil penelitian menyatakan bahwa pengamatan bobot benih awal, kadar air benih awal menunjukkan tidak berpengaruh nyata. Sedangkan data berpengaruh nyata terdapat pada pengamatan bobot benih setelah perlakuan pada perlakuan konsentrasi hormon giberelin dan kadar air benih setelah perlakuan pada perlakuan hormon giberelin dan lama perlakuan yang mana pada pengamatan bobot benih setelah perlakuan tertinggi yakni pada perlakuan konsentrasi hormon giberelin 300 ppm dengan lama perendaman 24 jam (G3L3) sebesar 4.28 g dan pada pengamatan kadar air benih setelah perlakuan tertinggi yakni pada perlakuan konsentrasi hormon giberelin 300 ppm dengan lama perlakuan (G3L3) yakni 50.54 %.Kata Kunci: Kopi Robusta, Air, Waktu

The soil physical properties are one of the components of soil fertility that function as a place for roots to penetrate. Different types of land uses affect the soil physical properties, especially on the availability of water and soil aeration which indirectly affects the availability of nutrients in the soil. Research on the soil physical properties of ex-gold mining, oil palm plantations and forests was carried out on Ultisol located in Tebing Tinggi Village, Dharmasraya Regency from April until October 2021. The objective of this study was to obtain the comparison of soil physics properties in ex-gold mining land with oil palm and forest land on Ultisol. The method on this study was a survey with purposive sampling on three different land uses (ex- gold mining land, oil palm land and forest) at a depth of 0-20 cm and 20-40 cm and it was replicated 3 times. The observed parameters were soil texture, organic matter, volume weight, soil pore space, soil water content, permeability, and soil aggregate stability. Based on soil analysis in the laboratory, it was obtained that the physical conditions of the soil in three different land uses, i.e the physical condition of the oil palm land and forest were better than the ex-gold mining land. The soil texture on ex-gold mining land was classified on sandy clay loam and sandy loam with a very low organic matter content (0,20-1,72 %) if compared with oil palm and forest land. The volume weight in each land use was relatively high with the total soil pore space was low except in oil palm land depths of 0-20 cm, which is 69,93 % vol (moderate). Permeability was slow to moderate with the soil aggregate stability classified as unstable to steady. Soil water content was relatively low except in forest land depths of 20-40 cm which very high criteria (33,93 %).

Pertumbuhan tanaman kakao sangat dipengaruhi oleh ketersediaan unsur hara di dalam tanah. Ketersediaan unsur hara ditentukan oleh sifat fisik, kimia dan biologi tanah. Pada tanah marginal seperti Ultisol memiliki tingkat ketersediaan unsur hara yang sangat rendah. Hal ini disebabkan oleh proses pelapukan yang intensif. Oleh karena itu, perlu dilakukan perbaikan kesuburan tanahnya. Salah satu upaya yang bisa dilakukan untuk memperbaiki kesuburan tanah Ultisol agar kakao dapat tumbuh dengan baik adalah dengan melakukan penambahan pupuk alam. Pupuk alam dapat berasal dari pemanfaatan sisa-sisa tanaman atau hewan. Salah satu diantaranya yaitu pemanfaatan limbah darah sapi, limbah ini belum banyak digunakan sebagai sumber pupuk alam. Penelitian ini dilaksanakan pada bulan November 2019 hingga April 2020, yang bertempat di kebun percobaan kampus 3 Universitas Andalas, Dharmasraya. Penelitian ini merupakan penelitian eksperimen yang disusun dalam Rancangan Acak Lengkap (RAL). Perlakuan yang dicobakan terdiri dari 5 taraf perlakuan yaitu: P0: 0 ml darah/L air P1: 40 ml darah/L air, P2: 60 ml darah/L air, P3: 80 ml darah/L air, P4: 100 ml darah/L air. Dari hasil penelitian diketahui bahwa penambahan pupuk cair darah sapi memberikan pengaruh terhadap pertumbuhan bibit kakao pada ultisol. Aplikasi pupuk cair darah sapi dengan dosis 40 ml – 100 ml pada tanaman kakao memberikan respon pertumbuhan yang lebih baik pada tanah ultisol, jika dibandingkan dengan tanaman yang tidak ditambahkan pupuk cair darah sapi. Hal ini dapat dilihat pada variabel pengamatan jumlah daun dan diameter batang. Dengan demikian pemanfaatan limbah darah sapi dapat dipertimbangkan sebagai salah satu sumber pupuk cair alami.

Abstract The lecturers and community-based science and technology service activities are carried out as an effort to control white root fungal disease caused by Rigidiporus microporus or Rigidoporus lignosus which is difficult to control by farmers because it attacks the root system of rubber plants. One effort that can be done to control this JAP disease is the application of Trichoderma sp in the nursery of rubber plants, so that the rubber seedlings that will be planted fries have been protected by Trichoderma sp. The partner in this service activity is the True Nursery Breeder farmer group which is a group of rubber seed breeder farmers. Farmers are trained to be able to propagate Trichoderma sp and utilize agricultural waste into compost using Trichoderma sp as a decomposer. This activity was held in Kenagarian Sungai Dareh, Pulau Punjung District, Dharmasraya Regency. The result of this activity is that the farmers succeeded in propagating Trichoderma sp using bran as a growing medium, farmers have also made compost from agricultural waste around their environment. After isolating the soil of rubber seed media that has been applied Trichoderma sp, it is known that Trichoderma sp successfully grows well in the soil media and the root system of rubber seedlings. Thus, farmers have been able to do nurseries usingTrichoderma sp as an initial effort to overcome the attacks of white root fungus. Rubber seeds with Trichoderma sp, compost and Trichoderma sp produced by the True Nursery breeders have been marketed to farmers and the community around Kenagarian Sungai Dareh, so that this activity can help improve the welfare of farmers.
