Abstract

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

Nurseries are one of the essential agronomic activities in oil palm cultivation. Oil palm seedlings are cultivated on a large scale, different from nurseries for other plantation commodities. The nursery expanse comprises various biotic components, one of which is Arthropods. This study aims to determine the Artropod community and its function in oil palm nurseries. The research was carried out at two nurseries, Nagari Gunung Medan and Nagari Kurnia Selatan, Dharmasraya Regency, West Sumatra Province. Sampling using the pitfall trap, yellow pan trap, insect nets, and direct collection methods. The results showed that the Arthropods that make up the oil palm nursery ecosystem were insects and spiders. Arthropods in oil palm nurseries act as phytophages, predators, parasitoids, and detrivores. Phytophage insects found in oil palm nurseries were 700 individuals consisting of 4 orders, nine families, and 14 genera/species. Predatory insects, parasitoids, and detritivores were found in as many as 466 individuals consisting of 5 orders, 14 families, and 16 genera/species. There are two species of spiders in oil palm nurseries: Pardosa sp and Oxyopes javanus. Valanga sp was the species with the highest number of individuals in oil palm nurseries.

Abstract

Nagari Sungai Abang is one of the areas in Lubuk Alung District, one of the rice production centers in Padang Pariaman Regency. One farming group that intensively cultivates rice is the Farming Business group. The problem with the farmer groups is their ignorance of the benefits of straw as a source of organic matter in the soil. The composting process is long, so farmers always burn rice straw after harvest in preparation for planting the following season. If the burning of straw is carried out continuously, it is feared that nutrients will be deficient in the soil. This activity aims to empower Farming Business groups in Nagari Sungai Abang, Lubuk Alung District, to utilize Plant Growth Promoting Rhizobacteria (PGPR) as a bio activator in making straw compost as organic fertilizer and an alternative to addressing the problem of straw waste in Nagari Sungai Abang, Lubuk Alung. This activity has been carried out in the Farming Group of Farmers in Sungai Abang Dalam Nagari Sungai Abang, Lubuk Alung District, Padang Pariaman Regency. The method used is outreach, counseling, and training to demonstrate making PGPR suspension and compost from straw. From the activities that have been carried out, ready-to-use PGPR is obtained as a bio activator reproduced in coconut water media and used as a bio activator to speed up the composting process. The conclusion of this activity is increasing farmers' understanding of the benefits of straw as a raw material for compost and the use of PGPR as a bioactivator in making straw compost.

Abstract

Cocoa pod borer (CPB) is one of the important pests of cacao crops in Indonesia. The percentage of plants attacked by CPB pests at Dharmasraya Regency in 2019 reached 59.93%. Therefore, it is necessary to have appropriate control measures in order to reduce the percentage of plants attacked by CPB pests. One of the controls that are considered capable to controlling CPB pests is the condomization method. The objectives of this research wereto study the effectiveness of cacao pods condomization against C. cramerella attack, and to determine the appropriate cacao pods size for condomization in controlling C. cramerella. The researchwas designed by a Completely Randomized Design (CRD) consisted of 3 treatments and 5 replications, each replication consisted of 2 samples. The treatments used were condomization of cacao pods sized 5-8 cm and 9-12 cm with plastic sized30 cm x 20 cm x 0.5 mm, and the controls. The data were analyzed ofvariance and Duncan's New Multiple Range Test (DNMRT) at 5% level significantly. The results showed that the cacao pods sized5-8 cm that were condomed could reduce the percentage of pod attacked by CPB pests from 89.96% to 40.00% and the percentage of cocoa beans damage from 35.45% to 2.46%. The average of cocoa beans dry weight   in this results showed a not too significant difference, ranging from 31.6 g - 47.7 g. CPB pest control using the condomization method on cacao pods is quite effective in controlling CPB pests. The best size for cacao pods to be condomed is 5-8 cm.Keywords: cacao, condomization, Cocoa Pod Borer, pods size 5-8 cm, and 9-12 cm

Abstract

Forest conversion to oil palm plantations forms a unique agroecosystem. Forests known as a source of biodiversity are bordered by oil palm plantations with low diversity. The location of the oil palm plantation, which is directly adjacent to the forest, is thought to affect the diversity of spiders found in the agroecosystem. This study aimed to determine the effect of the distance between oil palm plantations and forests on spider diversity. The research was conducted at oil palm production centers in West Sumatra Province, Indonesia, namely Dharmasraya Regency, Pulau Punjung District, Nagari Gunung Selasih, and Sungai Kambut. In oil palm plantations, 10 sample plots (1 m x 1m) were determined along the transect line, 1 km from the forest's edge. Spiders were collected using the pitfall trap, knockdown, and hand collection methods. The spider diversity was analyzed by applying the diversity and evenness index by Shannon-Wiener. The results showed that the distance of the oil palm plantation from the forest affected the diversity of spiders. The closer the oil palm plantation is to the forest, the higher the diversity of spiders. The results of this study can be one of the considerations for oil palm business actors to maintain forests as conservation areas for organisms that provide various ecosystem services, including spiders as predators of oil palm pests.

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.
