Abstract

An evaluation of the suitability of land for sugar palm cultivation was conducted to assess the land's ability to support maximum growth and production. Palm cultivation in Nagari Labuah Gunuang, Limapuluh Kota Regency, has not been optimal because the plants still grow wild without regard to land suitability. This study aims to determine the actual and potential land suitability classes and map land suitability for palm cultivation development. This study employed a field survey using the purposive sampling method on four land units, with sample point criteria selected based on overlay results and representing each land map unit. Additionally, soil sampling was conducted at a depth of 0–60 cm, followed by laboratory analysis. Land suitability was evaluated using a matching method that matched land characteristics with the requirements for palm tree growth. Spatial analysis was then performed using ArcGIS software to produce a land suitability map. The results showed that land suitability classes in Nagari Labuah Gunuang varied. Land units 1 and 4 were classified as unsuitable because they had a slope of more than 40%, while land units 2 and 3 were classified as marginally suitable with a slope of 15–25%. The main limiting factor on land units 2 and 3 is the risk of erosion. After improvement measures such as terrace construction and planting of ground cover crops, the potential suitability class of land units 2 and 3 can be upgraded to moderately suitable. The development of sugar palm cultivation in Nagari Labuah Gunuang can be carried out on land units 2 and 3.

Abstract

Pest attacks on rice plants can cause a detrimental decrease in production. Hymenoptera has many important roles in ecosystems, including as parasitoids and predators of pests. The purpose of this study was to determine the presence of Hymenoptera around tidal swamp rice in Indragiri Hilir Regency, Indonesia. Sampling used four traps, namely: 1) swing net; 2) yellow pan trap; 3) malaise trap; and 4) pitfall traps. The analysis was carried out by calculating the Shannon-Wiener diversity index (H'), the Margalef species richness index (D), the Pielou species evenness index (J). Hymenoptera found around tidal swamp rice areas of Indragiri Hilir Regency were 15.253 Hymenoptera insects consisting of 11 superfamilies, 37 families, and 304 morphospecies. Hymenoptera parasitoid had the highest diversity index value (4,80), followed by Hymenoptera pollinator (3,13) and Hymenoptera predator (3,11). The number of species of Hymenoptera parasitoid, pollinator, and predator obtained was 243; 31 and 76 species. The high diversity of Hymenoptera around tidal agricultural land optimizes its ecological role in the rice plantation ecosystem.

Abstract

Spodoptera exigua is the primary pest attacking shallot plants from the vegetative to the generative phase. Yield loss caused by S. exigua attack can reach 57%. Rhizobacteria have been known to be used as biocontrol agents for controlling insect pests. The research objectives were to determine and compare the effectiveness of Yuyaos and BPTPH rhizobacteria formula (Bacillus sp.) in suppressing the attack of S. exigua on shallot-growing areas. The study used a completely randomized design (CRD) of 3 treatments and five replications. The treatment consisted of shallot seedlings treated with two types of rhizobacteria (Yuyaos and BPTPH) and water (without rhizobacteria) as control before planting. Beneficial effects of the rhizobacteria on shallot plants were observed in the following variables, including the development of the S. exigua population, damage level of S. exigua, and shallot growth. The results showed that introducing Yuyaos rhizobacteria (RZ2.1AG1, Bacillus thuringiensis), which originated from the rhizosphere of the chili plant, was the best way to protect shallot plants from S.exigua. Effectively reduced the population of S.exigua (78.90%), leaf damage (62.12%), and damage intensity (38.88%). On the other hand, Yuyaos was also influential in increasing tuber growth (11.11%), plant height (43.29%), number of leaves (58.33%), and number of tillers (22.22%).

Abstract

Cacao (Theobroma cacao L.) is a key tropical commodity whose productivity is significantly constrained by insect pests, particularly mirid bugs such as Helopeltis theivora. This study aimed to quantify the population abundance and infestation intensity of H. theivora and to analyze their association with agroecosystem management practices in cocoa plantations of Lima Puluh Kota Regency, West Sumatra, Indonesia. Field surveys were conducted across six villages using purposive site selection followed by random sampling of plants. Pest populations were assessed through chemical knockdown and manual collection, while infestation levels were determined using standard percentage and intensity indices. A total of 206 individuals were recorded, with nymphs (63.6%) dominating the population structure. Pest abundance ranged from 0.05 to 0.35 individuals per stem. Infestation levels varied significantly across locations, with the highest infestation percentage (51.76%) and intensity (41.13%) observed in poorly managed plantations, while the lowest values (35.89% and 31.88%) occurred in well-maintained systems. Variations in pest dynamics were strongly associated with differences in sanitation, pruning, and pesticide application. The findings highlight the critical role of agroecological management and natural enemy conservation in regulating H. theivora populations. This study provides an empirical basis for developing location-specific integrated pest management (IPM) strategies to enhance cocoa productivity in tropical agroecosystems.

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

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.

Abstract

Orange is one of the horticultural commodities that deserve to be developed because it can be used as a good source of income for farmers. Efforts to increase the production of citrus plants cannot be separated from the problem of pest, which results in decreased production. Fruit flies are the most important pests that interfere with the production of citrus cultivation in Sungkai. Extension activities and monitoring of integrated pest management of fruit flies in citrus plantations in the Sungkai area of Padang City. The method applied in the extension of integrated pest management (IPM) for fruit flies is through training and Focus Group Discussions and making pilot demonstration plots. Participants in fruit flies' integrated pest management counseling activity are members of the P4S Sungkai Permai, Sungkai Permai Farmers Group, Bukik Bulek, and Pulau Indah, and all communities in the Sungkai area. The IPM technique used to reduce fruit fly pests in Sungkai is land clearing (sanitation). Prevention of fruit fly pests with sanitation has the advantage of low operating costs and low impact or hazard to worker health and the environment. Cleaning the remains of these plants means that we break the life cycle of pests, thereby reducing the pest population. Through this counseling, farmers know and understand how to implement land sanitation to control fruit fly pests. In addition, citrus farmers in Sungkai also have field demonstration plots of land sanitation techniques for citrus plantations to reduce fruit fly pests.
