Extensive utilization of fragile tropical peatlands ecosystem encourages a better understanding of spatiotemporal micronutrients distribution. The distribution of total Fe, Cu, and Zn in peat and their relationship with environmental factors were studied under oil palm plantation, Pangkalan Pisang, Koto Gasib, Riau, Indonesia. Peat samples were taken compositely inside the block using a combination of six factors, including a) the oil palm age (<6, 6-15, >15 years old), b) the peat thickness (< 3 and >3 m), c) season (rainy and dry), d) the distances from the secondary canal (10, 25, 50, 75, 100, and 150 m), e) the distances from an oil palm tree (1, 2, 3, and 4 m), and f) the depth of sample collection (0-20, 20-40, and 40-70 cm from the peat surface). Total Fe, Cu, and Zn were determined by the wet digestion method. These micronutrients observed in this study possessed high variability; however, they were within the expected range in tropical peatland. The entire micronutrients were statistically different by oil palm age, peat thickness, and distance from canal. Meanwhile, total Cu and Zn were also significantly different at each season. The oil palm age, peat thickness, and distance from the canal were the common factors controlling total Fe, Cu, and Zn in peat significantly. Moreover, total Cu and Zn were also dictated by season, distance from the oil palm tree, and depth of sample collection. Based on visual interpretation in PCA (principal component analysis), all micronutrients were categorized into two groups, separated by 2 m distance from the oil palm tree and 20 cm depth from the soil surface. Our study also highlights the dominance of the dilution over the enrichment process in peat, which requires further research to formulate micronutrients fertilization, especially for an extended cultivation time.

The amount of CO2 gas emissions in drained peatland for oil palm cultivation has been widely reported. However, the research addressing the contribution of litter respiration to peat and total respiration and its relationship with several environmental factors is found rare. The aim of this study was to measure peat and heterogeneous litter respiration of drained tropical peat in one year at a distance of 2.25 m and 4.50 m from mature oil palm trees of 14 years using the chamber method (Licor Li-830). In addition to CO2 efflux, we measured other environmental parameters, including peat temperature (10 cm depth), air temperature, groundwater table (GWL), and rainfall. Results showed that the mean total peat respiration (Rt) was 12.06 g CO2 m-2day-1, which consisted of 68% (8.24 g CO2 m-2day-1) peat (Rp) and root (Rr) respiration and 32% (3.84 g CO2 m-2day-1) of litter respiration (Rl) at the distance of 2.25 m from the palm tree. Meanwhile, at a farther distance, the Rt was 12.49 g CO2m-2day-1, the contribution of Rp was 56% (6.78 g CO2 m-2day-1), and Rl was higher than the closest distance (46%; 5.71 g CO2 m-2day-1). Thus, one-year observation resulting the mean Rt and Rr was 0.07–0.08 Mg CO2 ha-1 day-1, while Rl was 0.04–0.06 Mg CO2 ha-1 day-1. The means of Rt, Rp, and Rl were significantly different in the dry season than those recorded in the rainy season. The climatic-related variable such as peat and air temperature were chiefly governing respiration in peat under mature oil palm plantation, whereas the importance of other variables present at particular conditions. This paper provides valuable information concerning respiration in peat, especially for litter contribution and its relationship with environmental factors in peatland, contributing to global CO2 emission.

The study was conducted in the river system located at Wilmar oil palm plantation in Miri, Sarawak. The objective of the study is to determine the fish species diversity and composition in the streams and rivers in the oil palm plantations. Fish were sampled using a variety of fishing methods, including, scoop nets, cast net, and gill nets of different mesh sizes (1.0, 1.5, 2.0, 2.5, 3.75 and 4.0 cm) from 2 to 7 of February 2014. A total of 326 individual fish including 32 species of native fishes and one species of non-native fish from 19 genera, seven families and five orders were collected from seven locations. The cyprinid fish represented 62.20% of the total fish caught and was found in all the rivers surveyed. About six endemic species in Borneo such as Barbonymus collingwoodii, Barbodes banksi, Barbodes sealei, Hampala bimaculata Nematabramis borneensis and Nematabramis everetti were identified. However, only one species from families Bagridae, Balitoridae, Clariidae, and Hemiramphidae was sampled from the study sites. The higher fish species composition found in streams and rivers of the oil palm plantation landscapes could be attributed to the conservation of some areas of the plantation as high conservation value forest (HCVF) status, which have provided suitable habitat for fish species within the plantation aquatic environments.

Abstract: Oil palm was one of profitable industrial crops. Oil palm high demand in industries encouraged new plantation field opening as oil palm plantation by means of forest conversion method. From land acquisition to oil palm plantation management, tenurial conflict often occurs. This article aimed to map some existing researches concerning conflict of palm oil companies with indigenous and surrounding forest community in Indonesia. This article uses systematic review method by using conflict-related keywords as assisting tool in filtering the data in order to acquire matching articles. Conflict of palm oil companies with indigenous people and surrounding forest community was distributed into four types. Type 1 was the conflict related to land acquisition and HGU permit. Type 2 was the conflict related to plasma plantation development and land compensation which would be used for plasma plantation. Type 3 was the conflict related to Broken Promises and Unfulfilled CSR Commitment. Type 4 was the conflict which occurred during plasma plantation management by cooperatives and companies for oil palm production (TBS and CPO). Keywords: conflict, plantation, palm oil, indigenous people, people surrounding society   Intisari : Kelapa sawit merupakan salah satu produk tanaman industri yang menguntungkan. Tingginya permintaan kelapa sawit oleh pasar industri mendorong pembukaan lahan perkebunan baru untuk perkebunan kelapa sawit melalui konversi hutan. Konversi lahan sering terjadi konflik tenurial. Artikel ini bertujuan untuk memetakan penelitian-penelitian terdahulu mengenai konflik antara perusahaan perkebunan kelapa sawit dengan masyarakat adat/masyarakat sekitar hutan di Indonesia. Penelitian ini menggunakan metode sistematik review dengan menggunakan kata kunci sebagai alat bantu dalam proses penyaringan untuk mendapatkan artikel yang sesuai. Konflik antara perusahaan perkebunan kelapa sawit dengan masyarakat adat/masyarakat sekitar hutan dibagi menjadi empat tipe. Tipe 1 adalah konflik terkait akuisisi lahan dan perizinan HGU. Tipe 2 adalah konflik yang terjadi terkait pengembangan perkebunan plasma dan ganti rugi lahan yang akan digunakan untuk perkebunan plasma. Tipe 3 adalah konflik yang terjadi terkait janji yang tidak ditepati dan komitmen dari CSR yang tidak dipenuhi. Tipe 4 adalah konflik yang terjadi dalam pengelolaan kebun plasma oleh koperasi dan perusahaan untuk menghasilkan kelapa sawit (TBS dan CPO). Kata Kunci: kelapa sawit, konflik, masyarakat adat, masyarakat sekitar hutan perkebunan

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.
