Abstract

The main product of the palm plant is sap, which results from tapping the male flowers into palm sugar, soft drinks, vinegar, and alcohol. Apart from that, sugar palm plants can also produce food products such as palm fruit from female fruit, sugar palm flour for food in the form of cakes, bread, and biscuits, which comes from processing the pith of the plant stem and can be used as a source of bioethanol production.  However, there is limited research on how sugar palm agroecosystems influence the dynamics of herbivorous pests and predatory insect populations, making it essential to understand these interactions for sustainable plantation management. This research aimed to study the influence of sugar palm agroecosystems on the presence of herbivorous insect pests and predatory. The research was conducted in Nagari Labuah Gunung, Lima Puluh Kota Regency, West Sumatra Province. Observations were conducted on stretches of sugar palm plants aged 7-8 years or already producing. The sample plants were determined using purposive sampling, and labels were given to each tree that was part of the sample plants. Identify herbivorous and predatory insects obtained from the field and calculate the attack level. From the research carried out, it was found that management of sugar palm plants affects the presence of herbivorous and predatory insect pests, where no herbivorous insect pests were found on sugar palm plantations, and no herbivorous insect pest attacks were found on sugar palm plants on people's plantation land. Many types of predatory insects are found in sugar palm plantations, including Hymenoptera, Coleoptera, Orthoptera, Mantodea, Dermaptera, and Diptera.  These findings contribute to a deeper understanding of the ecological balance within sugar palm agroecosystems, emphasizing the potential role of natural predators in maintaining pest-free plantations and supporting sustainable agricultural practices.

Abstract

Termite are pests that often attack oil palm plantations. Information on the diversity of termite species that attack oil palm plants is needed in an effort to save oil palm yields. The method in this study used an observation plot measuring 50 m x 10 m. One observation plot was divided into observation sub-plots with a size of 5 m x 5 m in order to obtain 20 observation sub-plots. Each observation plot was carried out in eleven sub-districts in Dharmasraya Regency. Termite samples in each observation plot were identified in the laboratory.  Every termite found in the observation sub-plot was collected. The termites collected were from the caste of soldiers and workers. The termites were put into a collection bottle containing 70% alcohol and labeled, then identified descriptively by observing the characteristics of the termites including the shape and size of the head, mandible, and the antenna segments of the soldier caste. Identification was carried out using a Leica M205 C microscope and photographed with a Leica DFC450 camera. In this study there are 8 species of termites found viz Coptotermes curvignathus, Schedorhinotermes longirostris, Schedorhinotermes javanicus, Heterotermes indicola, Globitermes globosus, Dicuspiditermes nemorosus, Pericapritermes mohri, Macrotermes gilvus.

Abstract

Kecamatan Sembilan Koto merupakan daerah dengan mayoritas penduduknya sebagai petani sawah dan tanaman hortikultura. Permasalahan di Nagari Silago dari tahun ke tahun terkait praktik budidaya tanaman hortikultura adalah adanya serangan hama dari kelompok serangga lalat buah yang menyebabkan rusaknya buah dan tanaman sayuran masyarakat sehingga turunnya pendapatan masyarakat dan bahkan gagal panen. Selain itu permasalahan yang ada di Nagari Silago adalah masih minimnya pengetahuan masyarakat dalam memanfaatkan bahan-bahan yang mudah didapatkan dalam pengendalian hama lalat buah tersebut. Masyarakat biasanya lebih sering menggunakan insektisida kimia dalam bentuk formulasi instan yang dibeli dengan harga yang cukup mahal. Tujuan kegiatan pengabdian ini adalah untuk memberikan pengetahuan kepada masyarakat dalam membuat perangkap lalat buah yang ramah lingkungan dengan memanfaatkan botol bekas dan diberi atraktan metil eugenol sebagai zat pemikat agar hama lalat buah masuk dalam perangkap. Adapun manfaat dari kegiatan ini diharapkan masyarakat  di Nagari Silago dapat membuat perangkap lalat buah secara mandiri dan dapat membantu masyarakat dalam pengurangan pengeluaran biaya dalam pengendalian hama lalat buah tersebut.

Abstract

Limbah tandan kosong kelapa sawit (TKKS) merupakan limbah padat yang dihasilkan dari sisa pengolahan di pabrik kelapa sawit. Seiring dengan bertambahnya luas lahan kebun kelapa sawit menyebabkan jumlah limbah TKKS semakin meningkat. Meningkatnya jumlah limbah ini secara terus menerus akan menyebabkan terjadinya pencemaran lingkungan, seperti polusi udara akibat bau yang tidak sedap. Akan tetapi, limbah TKKS dapat memberikan manfaat jika diolah dengan baik. Salah satu cara yang bisa dilakukan dalam pengolahan limbah TKKS adalah dengan merubah limbah tersebut menjadi biochar. Biochar dari TKKS dapat dimanfaatkan untuk memperbaiki kualitas lahan di kebun kelapa sawit rakyat. Kegiatan pengabdian masyarakat yang terintegrasi dengan mahasiswa Kuliah Kerja Nyata (KKN) ini bertujuan untuk memberikan pelatihan cara membuat biochar dari limbah TKKS kepada kelompok tani Semoga Jaya yang berada di Kenagarian Koto Beringin Kecamatan Tiumang Kabupaten Dharmasraya. Melalui pelatihan ini, diharapkan petani dapat mengelola limbah tersebut secara mandiri dan berkelanjutan, serta memanfaatkannya dengan baik untuk perbaikan kualitas lahan kelapa sawit rakyat. Kegiatan pelatihan diikuti dengan antusias oleh petani, hal ini dapat dilihat dari banyaknya pertanyaan yang muncul selama kegiatan pelatihan berlangsung. Hal ini menunjukkan bahwa para petani sangat tertarik untuk menerima ilmu yang disampaikan, dan ingin mencoba  dan mengaplikasikan pembuatan biochar ini pada kebun kelapa sawitnya masing-masing.

Abstract

Endophytic bacteria in a plant tissue do not cause disturbance or damage to the plant. Phytohormones produced by endophytic bacteria can increase plant growth and function as antimicrobials. The study aims to explore, select, and characterize the morphology of endophytic bacteria originating from the stems and roots of coffee plants from Solok Radjo. Morphological observations were carried out after obtaining a single isolate of endophytic bacteria, then a Gram test with 3% KOH and a hypersensitive reaction test on water henna plants were carried out to determine the pathogenicity of the endophytic bacteria. A total of 35 isolates were obtained from the isolation results, namely 23 isolates from the stem and 12 isolates from the roots. The results of morphological observations of endophytic bacterial colonies on Nutrient Agar (NA) media were dominated by irregular colony shapes, smooth and shiny surfaces, flat elevations, and yellowish-white colony colors. Gram testing with 3% KOH obtained 17 isolates classified as Gram-positive and 18 isolates as Gram-negative. Hypersensitive observations that showed symptoms of necrosis (positive reaction) were 19 isolates, and no symptoms of necrosis (negative reaction) were 16 isolates.

Abstract

Rice is a primary necessity for the Indonesian people, as it serves as a source of energy and carbohydrates. Rice cultivation requires strategic approaches to increase production, aiming to prevent threats to Indonesia's food security. One strategy that can be applied is the jajar legowo rice planting system. The jajar legowo system is a technique that manipulates planting distances to increase rice yields, resulting in a greater number of edge plants. This activity aims to enhance farmers' understanding of rice cultivation using the jajar legowo system to achieve better harvests and to boost their enthusiasm in working on their agricultural land. The activity was conducted on the rice fields owned by the Tanjung Raya farming group, located in Nagari Sungai Dareh, Pulau Punjung District, Dharmasraya Regency. The method employed involved directly practising the jajar legowo rice planting system in the farmers' rice fields. The activity proceeded smoothly, successfully increasing the farmers' understanding of *jajar legowo* rice cultivation to achieve better harvests. Both the farmers and students involved in the activity were able to perform their tasks according to the specified guidance. Looking forward, it is hoped that similar activities will be held, as this initiative by the students of Campus III Universitas Andalas Dharmasraya aims to provide benefits and positive contributions to the surrounding community.

Abstract

Termites are one of the organisms that have the potential to reduce oil palm productivity, so it is necessary to identify the species and map their distribution to support more effective and sustainable management. This study was conducted to identify termite species and map their distribution in oil palm plantations in Timpeh District, Dharmasraya Regency, Indonesia. This study used a survey method with purposive sampling based on several criteria, including the presence of plant attack symptoms, air humidity ≥ 60%, the presence of rotten wood, the presence of termite nests, and the sampling location was selected in oil palm plantation areas located on the edge of local roads at a distance of about 0-15 meters. The termite samples obtained were identified morphologically using a microscope and identification keys. Termite distribution mapping was performed using ArcGIS 10.8 software, while the relationship between termite presence and environmental factors (temperature, light intensity, and humidity) was analyzed using Redundancy Analysis (RDA). The results showed that there were six termite species in Timpeh Subdistrict, namely Macrotermes gilvus, Coptotermes curvignathus, Pericapritermes mohri, Dicuspiditermes nemorosus, Nasutitermes longinasus, and Termes propinquus. The species M. gilvus has the widest distribution throughout the subdistrict and is not significantly influenced by environmental factors, but rather by its high adaptability. Meanwhile, the other species have a more limited distribution and tend to be influenced by factors such as humidity, light intensity, and the availability of organic material. The mapping results provide a crucial basis for determining priority areas for control and termite management strategies in oil palm plantations, enabling more effective and efficient approaches to be implemented.
