Abstract

Pollination is an essential part of increasing crop production. One insect that acts as a pollinator on plants is the Galo-galo bee. Stingless bee cultivation can help in the pollination process and serve as a producer of pure honey, which also has the potential to increase farmers' income. This activity aims to enable partner groups at the Andalas University campus to cultivate stingless bees on agricultural land. The methods used in this service are counseling, mentoring, training, and piloting. Extension materials were carried out to increase farmers' knowledge about the potential of stingless bees, the introduction of natural colony trapping methods, and bee food sources. The service team has brought several Galo-galo bee colonies that farmer groups in Sungkai will maintain. By bringing the colony bees, farmers are given other material, namely how to transfer the colony to the cultivation box, install the honey box, and harvest. The results of this activity are as follows: 1) Increased knowledge, interest, and skills of partners in raising Galo-galo, which is integrated with agriculture. 2) Partner has a new business unit in the form of Galo-galo cattle. 3) Partners have a new commodity produced, namely Galo-galo honey. 4) Partners know and can cultivate bee food plants. This activity ran smoothly, and the target of the movement was achieved well. Farmers participating in the service have cultivated stingless bees on managed agricultural land.

Abstract

Nagari Lubuk Karak is administratively located in the District of Nine Koto, Dharmasraya Regency, West Sumatra Province. Nagari is located in a sloping hill area with relatively good forest cover. However, today's environmental conditions in Nagari Lubuk Karak are constantly facing various threats that can damage the sustainability of the ecosystem, which are often caused by economic factors. This activity aims to provide education to the community in synergizing ecological and economic aspects so that the sustainability of the ecosystem in Nagari Lubuk Karak, which is in the upstream area, can always be maintained without compromising the community's welfare. This can be done by integrating reforestation activities using tree seeds that have economic value while at the same time intensifying rice cultivation owned by farmers by implementing the jajar legowo cropping system. This activity was carried out from 08 to 09 October 2022 in Nagari Lubuk Karak, Sembilan Koto District, Dharmasraya Regency. The implementation of the activity consisted of several stages, namely the socialization of reforestation activities and the application of the jajar legowo rice planting system, focus group discussions, and demonstrations of planting tree seedlings. The results of this activity can increase the knowledge and skills of the community regarding the importance of reforestation using tree seeds that have economic value while at the same time intensifying rice cultivation belonging to farmers by implementing the jajar legowo cropping system to increase farmers' income so that the economic and ecological aspects can work synergistically.

Abstract

Sugar palm (Arenga pinnata Merr.) is a high-value commodity whose reproductive success depends heavily on insect-mediated pollination. However, empirical data regarding insect diversity and their activity patterns across different altitudinal gradients remain scarce. This study aimed to identify the diversity of pollinator and visitor insects and evaluate their correlation with abiotic factors across three altitude strata: 500–700 masl, 700–1000 masl, and 1000 masl in Lintau Buo Utara, West Sumatra. Using a survey method with purposive sampling, observations were conducted over four weeks utilizing malaise traps, yellow sticky traps, and visual counts. A total of 857 individuals were recorded, consisting of 712 pollinators (dominated by Apis, Vespa, Episyrphus, and Polyrhachis) and 145 visitors (including Aphrophora, Macroglossum, and Spodoptera). Ecological analysis revealed a moderate overall diversity index (H' = 2.04), with pollinators showing higher evenness (E = 0.92) compared to visitors (E = 0.89). The most optimal pollination activity was consistently observed at elevations of 700–1000 masl. Pearson correlation analysis demonstrated that rainfall and relative humidity were the primary environmental drivers, exhibiting significant and robust negative correlations with insect presence (r = -0.94, p 0.05 for rainfall; r = -0.64, p 0.05 for humidity), whereas air temperature showed a non-significant moderate influence (p 0.05). Furthermore, a perfect positive correlation was found between pollinator and visitor patterns (r = 1.00, p 0.01). These findings suggest that medium-altitude agroecosystems provide the most supportive microclimate for sugar palm pollinators, though high precipitation remains a critical limiting factor for their foraging efficiency.

Abstract

Ultisols have a very high P sorption capacity, which limits the availability of P to plants. Therefore, it is necessary to understand the P sorption-desorption mechanism after humic substances (HS) amelioration to improve fertilizer efficiency and land productivity. This study has examined the complexity of phosphorus fixation and the potential of HS in modifying the surface charge of Ultisols. This study used the batch equilibrium method and the Freundlich and Langmuir isotherm model approaches. Meanwhile, the surface charge characteristics of Ultisols, amended with humic substances (HS) from various potential ameliorants (control, HS-chicken manure, HS-black soldier fly, HS-wet decanter solid, and HS-peat), were evaluated using a completely randomized design with three replications. The HS from potential ameliorants significantly increases pH, PZC, electrical conductivity (EC), mineral and organic matter composition, CEC, and reduces potential redox (Eh), thereby increasing the soil's negative charge and buffering capacity. The HS—wet decanter solid and chicken manure were most effective, as they were proven to remove Al-exchange to unmeasurable levels through strong complexation between Al³⁺ and carboxylate and phenolic groups. The HS—wet decanter solid and chicken manure also drastically reduce P sorption and increase desorption through ligand competition and blocking of Al/Fe reactive sites, which resulted in increased P availability up to >600 mg kg-1 P2O5 at a concentration of 1000 mg L-1 P or 2290 mg kg⁻¹ P₂O₅ or 6.37g SP-36 per liter or 6.37 kg SP-36 per hectare for an application volume of 1,000 liters per hectare.

Abstract

Increasing the production of robusta coffee plants (Coffea canephora) can begin with selecting quality seeds. Improving seed quality can be done through fertilization using ameliorants and organic materials. Volcanic ash and goat manure are ameliorants and organic materials used in improving the planting medium. This study used a completely randomized design (CRD) with two factors: volcanic ash (25, 50, 75 g/polybag) and goat manure (15, 30, 45 g/polybag). The results of this study showed an interaction between volcanic ash and goat manure on the growth in height, shoot dry weight, and the root crown ratio of robusta coffee seedlings. The application of volcanic ash affects plant height, stem diameter, and the root crown ratio of robusta coffee seedlings. The application of goat manure affected plant height, leaf number, and the root-to-shoot ratio of Robusta coffee seedlings. The best ratio was 50 g volcanic ash per polybag and 45 g goat manure per polybag, which optimally increased the growth of Robusta coffee seedlings compared to other treatments. These results indicate that using volcanic ash with goat manure can be an effective alternative organic fertilizer to support coffee seedling growth and improve the fertility of the growing medium.

Abstract. Ikhsan Z, Hidrayani, Yaherwandi, Hamid H. 2020. The diversity and abundance of Hymenoptera insects on tidal swamp rice field in Indragiri Hilir District, Indonesia. Biodiversitas 21: 1020-1026. Hymenoptera is one of the four largest insect orders and it plays a vital role in human life as pollinators, parasitoids, and predators. Hymenoptera parasitoids are particularly important as agents of biological control of pest. The objective of this research was to study the diversity and abundance of Hymenoptera on tidal swamp rice field in Indragiri Hilir District, Riau Province, Indonesia. Samplings were conducted in 3 sub-districts of rice production centers, namely Batang Tuaka, Keritang and Reteh, using four trapping techniques (i.e. insect net, malaise trap, pitfall trap, and yellow pan trap). Shannon diversity index (H '), Krebs evenness index (E), and Jaccard similarity index (Is) were calculated. We found 4,701 individuals consisting of 39 families and 319 species of Hymenoptera at the three studied areas. Tidal swamp rice in Indragiri Hilir District had a high species diversity of Hymenoptera parasitoids and Hymenoptera predators, but a moderate species diversity of Hymenoptera pollinators. Species diversity and evenness of Hymenoptera parasitoids and predators were higher in Keritang than in Batang Tuaka and Reteh. The families of Formicidae, Braconidae, Ichneumonidae, and Scelionidae had the highest number of species, while Formicidae, Scelionidae, Diapriidae, and Braconidae had the highest number of individuals. Based on these findings, the abundance and diversity of Hymenoptera insects in Indragiri Hilir District have the potentials to be developed as biological agents to control pests on tidal swamp rice in this area.

Abstract. Ikhsan Z. 2022. Diversity of Hymenoptera parasitoid species in rice cultivation and their correlation with environmental factors in tidal swamp land. Biodiversitas 23: 2262-2269. Environmental factors can affect biodiversity in a landscape. Differences in microclimate conditions can affect the presence of parasitic Hymenoptera in rice cultivation. This study investigated: (i) Landscape structure and microclimate on tidal swamp rice; (ii) Diversity and abundance of parasitic Hymenoptera; (iii) Correlation of parasitic Hymenoptera with their landscapes and microclimate. Determination of sample plots was made using the line transect method in rice cultivation in four tidal swampland landscapes. Data analysis was performed by calculating the Shannon-Wiener diversity index (H'), the Margalef species richness index (D), and the Pielou species evenness index. The relationship between parasitic Hymenoptera and environmental factors was analyzed using Pearson correlation analysis, principal component analysis, and canonical correlation analysis. Based on the diversity index (H'), three rice fields in complex landscapes had a higher diversity of Hymenoptera parasitoid species than simple landscapes. The presence of Parasitic Hymenoptera on tidal swamp rice can be affected by the landscape's structure and microclimates. Humidity is the microclimate variable that most influences the abundance of Parasitic Hymenoptera in the tidal swamp landscape. Good microclimate management is needed to increase the presence of Parasitic Hymenoptera in tidal swamp rice.

Abstract. Anggraini E, Sinaga TM, Irsan C, Herlinda S, Muslim A, Hamidson H, Sefrila M, Kurnianingsih A, Aryani D, Antoni M, Ikhsan Z. 2024. Insects found in different ages of coconut viridis variety in Sri Tiga Village, Banyuasin District, South Sumatra, Indonesia. Biodiversitas 25: 2637-2647. Coconut (Cocos nucifera L.) is a high-value export commodity and has promising potential on the global market. The existence of insect species is very important in coconut cultivation. The coexistence of insects and plants is interconnected because plants provide habitat and food sources for insects. However, the correlation between plants and insects still needs to be discovered to many people. Therefore, a comprehensive assessment of insect biodiversity in an environment is important to be carried out. This study revealed the structure of the insect community associated with coconut plants and weeds around coconut trees. Therefore, this is a novel and pioneering study that aims to determine the insects associated with coconut plants. This study was conducted by surveying community-owned coconut plantations in Sri Tiga Village, Sumber Marga Telang Sub-district, Banyuasin District, South Sumatera, Indonesia. The observation was carried out during July and September of 2023. The data-gathering process involved identifying three coconut plantations with varying ages of coconut trees (8, 5, and 2 years old). Data collection was carried out using the purposive sampling method by direct observations and using traps such as insect nets, light traps, and pheromone traps. Collected specimens were identified using a microscope in the Laboratory of Entomology, Department of Plant Pests and Disease, Faculty of Agriculture, Universitas Sriwijaya. The results of this study found 12 insect species in coconut trees, namely Oryctes rhinoceros Linnaeus 1758, Aspidiotus sp., Nipaecoccus nipae Maskell 1893, Aleurocanthus sp., Apis cerana Fabricius 1793, Cotesia congregata Say 1836, Dolichoderus thoracicus Smith 1860, Oecophylla smaragdina Fabricus 1775, Provespa sp., Pteroma pendula de Joannis 1929, Metura sp., Metisa plana Walker 1883. The predominant insect pests identified were Aspidiotus sp., N. nipae, and Aleurocanthus sp. Furthermore, the most predominant insects that served as insect scavengers were Polyrhachis sp. and O. smaragdina. Meanwhile, in the weeds around coconut trees, there were found six insect species, namely Aulacophora lewisii Baly 1866, Eumorphus westwoodi Guérin 1858, Mactrotermes sp., Conocephalus sp., Dianemobius sp., and Tettigidea sp.

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.
