Parasitoids play an important role in controlling pests, including pests of oil palm. To maximize biological control technique using parasitoids, interactions between pests and parasitoids need to be studied. This research aimed to study parasitoid diversity and host-parasitoid interaction in oil palm plantation with the different management system. The field research was conducted in oil palm plantation own by smallholder and company (PT Humusindo) in Jambi. Sampling insects was conducted by collecting pests (parasitoid host) on oil palm trees with age of four years old. Eggs, larvae, and pupae of the pests were taken directly by hand then reared in the laboratory to know their parasitoids. Pests and parasitoids emerged were identified up to morphospecies or species level. A total of 176 lepidopteran pests consisting of 15 morphospecies and 6 families, and 650 parasitoids consisting of 21 morphospecies and 12 families have been collected. Nine morphospecies of pests from 25 individuals were found in smallholder plantation and 14 morphospecies of pests from 151 individuals in company plantation. Eight morphospecies of 26 parasitoids were found in smallholder plantations and 8 morphospecies of 624 parasitoids in the company plantation. The interaction structure between pests and parasitoids is more complex in the company plantation than in smallholder plantations. Family Braconidae and Ichneumonidae are the most parasitoids found and associated with nettle caterpillars. The different of the management system of oil palm plantation did not affect the diversity and abundance of pests as well as their parasitoids in oil palm plantations.

Malaysia oil palm industry is the leading commodities and one of the major contributors to the Malaysia economic after oil and gas sector. Malaysia and Indonesia palm oil plantations are the major commodity producer with Malaysia currently being the world’s second-largest area of oil palm after Indonesia. Together these two countries account about 84% of total world production and 88% of global exports. With the increasing price and demands for the Crude Palm Oil (CPO) and with the 4.69 million hectares that were planted with oil palm trees, plantation industry and estate managers has to look into the most crucial factor that will decide the yield and quality of the CPO that is being sent to the mill. Typically, palm oil plantations include production areas requiring supporting infrastructure such as buildings, roads and services/management. When there is a better management of the roads in the estates, better Fresh fruit Bunch (FFB) and CPO quality will be sent to mill and processed. Road transport has a fundamental meaning for the sustainable agriculture. Poor quality and inadequate coverage of roads, lack of maintenance operations and outdated road maps continue to hinder economic development in the plantation. This work focuses on studying the present state of road infrastructure and its mapping in Felda Trolak Utara, Perak. The road infrastructure of the study area is studied by GPS and GIS based methodology. Data of road infrastructure characteristics were collected from GPS device and road infrastructure of the test sites then analyzed in GIS environment. The results of this study may be applied to road infrastructure mapping in oil palm plantation in general context, although with certain limits. In particular, the “noise” of road network occurred and need to rectify the topologies of the network.

Ants are social insects which widespread and play many important roles in an ecosystem. Myopopone castanea ants are a predator for the pre-adult stage of pest Oryctes rhinoceros which is one of the important pests in oil palm plantations. At the oil palm plantations, M. castanea and pre-mature stadia from pests O. rhinoceros live on decaying palm oil stems. This study aimed to explore the presence and the microhabitat characteristics of M. castanea ant in oil palm plantation so that mass rearing of M. castanea ants can be carried out in the laboratory to support the natural enemy augmentation program in biological control of O. rhinoceros pest. The exploration of ant nests was carried out in two plantation locations: smallholder oil palm plantations in Tanah Merah sub-district, Binjai Selatan Subdistrict, Binjai and PTPN 2 and PTPN 4 in Deli Serdang and Serdang Bedagai districts, North Sumatra Province. The results showed that the colonies of M. castanea in both of plantations vary greatly in the size of the number and stage of the ant development stage. Average of abiotic factors in the microhabitat of M. castanea ants in PTPN plantation (t = 29.7 0C, Rh = 70%, pH = 6.03 and C / N ratio = 66.18%), while for smallholder plantation (t = 29.1 0C, Rh = 70.9%, pH = 6.39 and C / N ratio = 69.01%). A suitable abiotic environment will support life and mass rearing of M. castanea ant colonies.

Surveillance and Mapping of Basal Stem Rot Disease in Oil Palm Plantation Using Unmanned Aerial Vehicle (UAV) and Multispectral Camera Basal stem rot (BSR) disease caused by Ganoderma boninensis is still a major disease in oil palm plantations both in Indonesia and Malaysia. In some countries, remote sensing approach has been used for monitoring BSR in oil palm plantation. However, the utilization of satellite imagery in remote sensing especially in vegetation study on the tropical region was often limited by cloud cover. A drone or unmanned aerial vehicle (UAV) utilization is the best way to deal with cloud cover in the tropic region. Machine learning of random forest (RF) and satellite imagery used in the BSR study produced good accuracy. This research was aimed to identify and monitor the BSR infection on individual oil palm trees using an UAV and multispectral camera and RF classification. The results showed that the data acquired from UAV was affected by cloud shadows. The RF classification of healthy and infected oil palm trees by BSR disease and the spreading map of BSR infection was affected by cloud shadows. The highest accuracy of healthy and infected oil palm by BSR was 79.49%. Reflectance calibrator, digital to reflectance conversion, and model implications to build spreading map of BSR infection need to be conducted both on the clear area and the cloud shadow-covered area. Moreover, the UAV-based data should be considering the cloud view on the coverage area.

Effect of Natural Habitat on Diversity of Hemipteran Predator in Oil Palm Plantation. Utillization of natural enemies in controlling oil palm pests still encounters obstacles, in particular, how natural enemies can survive and establish in oil palm plantations. The existence of natural habitats around oil palm plantations can allegedly support the occurence of natural enemies. The objective of this study was to investigate the effect of the presence of natural habitats on diversity of hemipteran predators in oil palm plantations. Field research was conducted in oil palm plantations located in Pangkalan Bun, Central Kalimantan. The plots were oil palm plantations with different distances from natural habitat i.e. near (less than 200 m), medium (about 2 km) and far (about 5 km). Each plot was selected six trees for fogging using insecticide with active ingredient lamda cyhalothrin. Based on research result, diversity of hemipteran predator in oil palm plantion was found 19 species belong to 2 families. The most dominant hemipteran predator was Sycanus sp., Eocanthecona sp. and Reduviidae sp5. The distance of oil palm plantation from natural habitat did not affect species richness, abundance and composition as well as recolonization of hemipteran predator in oil palm plantation. Abundance of hemipteran predator tend to decrease in different observation time, except Sycanus sp. Sycanus sp was likely has ability to rapidly recolonized and their occurrence were influenced by flowering vegetation in oil palm plantation.

Abstract Dungus Iwul Nature Reserved (CADI) is a remnant patch of tropical rainforest converted into plantations with neither past data nor study in macrofungi. In this article, we explored and identified macrofungal fruitbody in CADI and PTPN VIII Oil Palm Plantation (PTPN) around the nature reserve. The inventory was carried out with the opportunistic sampling methods assisted by the line intercept. Morphological characteristics were used to identify the macrofungal fruitbodies species. We found that the species richness in the study area stood at 120, with 70 species found in CADI, 23 species in PTPN planted in 2003, and 57 species in PTPN planted in 2004. These 120 species consist of 76 genera, 41 families, 11 orders, and four classes in Subkingdom Dikarya. Schizophyllum commune and Marasmiellus candidus in CADI and S. commune in PTPN planted in 2003 and 2004 were the species found with the highest relative frequency. Neither sign of basal stem rot on oil palm trees nor Ganoderma fruitbodies were found in both PTPN study locations, even though the fruitbodies were found in CADI. Further research is needed to determine if nature reserve could be a barrier against pathogens of monoculture oil palm plantation in a similar landscape model.

Biodiversitas 21: 1326-1331. Natural habitat existence in oil palm plantation has high conservation value and plays an important role in maintaining biodiversity. However, different taxa may have different responses to the presence of natural habitats. This research was aimed to investigate the effect of natural habitat existence on ant and termite diversity in oil palm plantation. The field research was conducted in oil palm plantation located in Central Kalimantan, Indonesia. Twelve plots of oil palm plantation with different habitat characteristics were selected. Ants and termites were sampled using hand collection in six subplots for each plot. In total, 38 species of ants and 9 species of termites were collected from all research areas. The results showed that the area of natural habitats and the distance of oil palm field to natural habitats affected the diversity of termites in the oil palm plantation, but ant diversity did not show to be affected by the same conditions. Based on the generalized linear model, the area of natural habitats in the oil palm plantation had a negative relationship with the diversity of termites. In conclusion, the termite species community is more affected by natural habitats than ants in oil palm plantation.

Kelapa sawit merupakan salah satu tanaman meningkat paling pesat di dunia, dan mencakup lebih dari 13 juta ha di Asia Tenggara. Sumatera memiliki sejarah yang relatif panjang budidaya kelapa sawit komersial, dan banyak perkebunan telah menggantikan hutan hujan. Biasanya ini perkebunan monokultur mendukung spesies lebih sedikit daripada hutan, namun ada sangat sedikit informasi yang tersedia untuk kelelawar. Kami mencicipi kelelawar pemakan serangga di Sumatera Barat dalam perkebunan kelapa sawit matang di mana beberapa tutupan hutan dipertahankan di fragmen hutan di bukit-bukit dan di sepanjang sungai. Menggunakan total 180 kecapi perangkap malam kami dibandingkan dengan komunitas kelelawar dalam tiga jenis habitat: patch hutan, zona riparian dan perkebunan. Total kami ditangkap 1108 kelelawar yang mewakili 21 spesies dan 5 keluarga, dan mayoritas ini (dalam hal spesies dan kelimpahan) ditemukan di fragmen hutan. perkebunan kelapa sawit ditemukan menjadi habitat miskin untuk kelelawar - hanya empat orang dari dua spesies ditangkap. daerah pinggiran sungai didukung keanekaragaman menengah, dan mungkin penting sebagai koridor satwa liar antara fragmen hutan. Kata kunci : Biodiversitas, keleawar Microchiropteran
