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.

This study was conducted to determine the composition of weed vegetation in Acacia mangium plants and to see differences in the composition of weed vegetation in several age classes of Acacia mangium plants in industrial plantations (HTI). This research was conducted in June to August 2018 in the industrial plantation of PT. Bukit Raya Mudisa (BRM) main road Km 13.7, Jorong Lubuk Mansagu, Kenagarian Koto Nan IV Di Bawah, Sub-district IX Koto, Regency Dharmasraya, Province of West Sumatra. The method used in this research is survey method by laying out the plot by purposive sampling in A. mangium gardens that are 2, 3 and 4 years old. At each age of the plant 2 observation plots were made measuring 40m × 40m in the plot. There were observational sub-plots measuring 1m ×1m in 10 plots of observation on a diagonal line with a total of 60 plots of observation. Based on the results of the analysis, there were 15 species belonging to 10 families. The number of weed species found in class 2, 3 and 4 respectively were 11, 9 and 11 species. The family of weeds that have the most species is the family Poaceae. Weeds are dominant under A. mangim plantations age 2, namely A. gangetica (38.26%), P. crinitum (14.81%) and I. cylindica (14.37%), almost the same as weeds under A.mangium plantations age 3 years namely A. gangetica (31.54%), A. compressus (20.49%), A.sessilis (19.50%), and P. crinitum (14.41%). The dominant age of 4 years weeds are A.gangetica (43.11%), A. sessilis (15.50%), and P. crinitum (15.36%). Weeds that dominate the A.mangium plantations are included in the group of broad-leaved weeds, so weed control is recommended in A. mangium plantations against broadleaf weeds.

One of the obstacles faced in oil palm cultivation, especially in the immature plant phase, is weeds, weeds can inhibit oil palm growth. So that weeds require special attention during cultivation, the presence of these weeds will become competitors for oil palm plants in fulfilling nutrients, light and water. This study aims to determine the composition of the types and vegetation structure of weeds in immature oil palm plants in large plantations so that the dose of herbicide with active ingredient Methyl Metsulfuron 20% is effective in controlling weeds in immature oil palm plantations in large plantations and studying the phytotoxicity of herbicides made from 20% active Methyl Metsulfuron in immature oil palm trees in large plantations. This study used a randomized block design (RBD), which consisted of 7 levels of treatment, 5 of which used the herbicide methyl metsulfuron 20% at a dose of 87.50 g / ha, 75.00 g / ha, 62.50 g / ha, 50.00 g / ha, 37.50 g / ha. ha and 2 including mechanical and control weeding which is repeated 4 times. Data analysis was performed with the F test, followed by the DMRT test at 5% level. The results showed that there were two species of weeds that dominated the research area, namely B. mutica and A. gangetica weeds with SDR values of 33.13% and 24.73%. The application of herbicides made from 20% methyl metsulfuron as active ingredients in controlling weeds in immature oil palm plantations is able to control 2 types of weeds, namely weeds including Melastoma malabathricum, Clidemia hirta with the best dose of 50.00 g / ha and 37.50 g / ha from the first 4 weeks up to 12 Weeks After Application (MSA).

Introduction: The availability of food sources influences the abundance of insect pollinators. The interaction between plants and insect pollinators is a symbiotic mutualism. In addition, the use of a plant barrier could attract insect pollinators in foraging activities. The study aimed to determine the effect of plant barrier on the abundance of insect pollinators and the yield of chili pepper. This research was carried out on agricultural land in Lumpoknyo village, North Luwuk, Banggai Regency, in July - December 2020. Methods: The research was carried out using a randomized block design, and four treatments, namely chili plants without barriers and covered with nets (P0 or control), eggplant plant barriers (P1), plant barriers with Zinnia sp and Cosmos caudatus (P2), and tomato plant barrier (P3). Observations were made every day at the time of flowering for 14 days. Sample collection of insect pollinators is done by taking insects that visit chili flowers using a sweep net. Results: Three species of insect pollinators were collected, namely Bembecinius sp, Ceratina sp, and Nomia sp. 730 individuals were found on eggplant barriers, 660 individuals on Zinnia sp and Cosmos caudatus barriers and 592 on tomato barriers. The highest individual is Ceratina sp (810 individuals), followed by Nomia sp. (799 individuals), and Bembecinius sp (373 individuals). Chili pepper cultivation using eggplant barrier yielded 4,93 kg/plot, Zinnia sp and Cosmos caudatus barriers 3,96 kg/plot, tomato barrier 3,62 kg/plot, and the lowest yield was shown in chili pepper fields covered with insect nets. of 2,00 kg/plot. Conclusion: The barrier system using eggplant is considered effective for increasing the abundance of insect pollinators and the yield of chili pepper.

Deforestation or functional change from forest to non-forest plays a role in changing ecosystems and species within it. Insects as one of the faunas in it is an interesting aspect to be studied, especially ants. The research was conducted in Nagari Gunung Selasih and Sungai Kambut, Pulau Punjung District, Dharmasraya Regency, West Sumatra from November 2017 to January 2018. This study aims to determine the diversity of ants in the palm oil plantation ecosystem bordering the forest ecosystem. This research takes the form of a survey where the Purposive Random Sampling method was used for points sampling. Hand Collecting, Bait Trap, and Pitfall Trap sampling methods were applied for each plant. Identification of the samples obtained was carried out at the Animal Taxonomy Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences, Andalas University, Padang. Total ants (Hymenoptera: Formicidae) collected during the study were 3,046 individuals consisting of 5 subfamilies, 15 genera, and 29 species. The most dominant species was Anoplolepis graciliphes, followed by Odontoponera denticulate and Odontomachus simillimus. Based on the results of the study, it can be concluded that the level of abundance and diversity of ant species is not directly affected by the distance from the forest ecosystem, but it is strongly influenced by the composition of environmental factors such as temperature, humidity, light intensity, altitude, and management of existing habitats and vegetation.

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.
