Abstract

Apis cerana became a common species for beekeeping activities in Indonesia. The sustainability of beekeeping activities depended on the availability of feeds in forests with various plant species, which served as honey bee forage. Therefore, this study aimed to determine the forage plant diversity for A. cerana beekeeping in Wanagama Education Forest, Gunungkidul, from November 2018 to April 2019. Data collection was done through the inventory of trees and understorey plant species around the apiary locations to measure their abundance, flowering conditions, and the number of honey bees on the flower. The analysis indicated that 20 species (10 families) of trees and 60 species (19 families) of understorey plants had potential forage. The observation revealed that honey bees collected nectar and pollen from seven species of trees and 12 species of understorey plants. The highest visitation intensity was in the morning from two trees (Acacia mangium and Eucalyptus grandis) and three understoreys (Oxalis barrelieri, Passiflora suberosa, and Zea mays). Information on potential plant species for honey bee forage could improve beekeeping development in Wanagama Education Forest.

Abstract

ABSTRAKPengelolaan lahan gambut untuk pengembangan HTI Acacia crassicarpa diawali dengan pembuatan saluran drainase dan pembukaan lahan (land clearing) yang kemudian dilanjutkan dengan penyiapan lahan untuk penanaman, sedangkan kegiatan pemeliharaan meliputi pemberantasan gulma dengan menggunakan herbisida dan pemupukan. Kegiatan pengelolaan dan pemeliharaan tentunya mempunyai dampak bagi kondisi ekologis lahan gambut. Perubahan kondisi ekologis terjadi karena perubahan lahan yang selanjutnya berpengaruh terhadap kelimpahan dan keragaman fauna tanah.Kelimpahan dan keragaman fauna tanah serta fungsi ekosistem menunjukkan hubungan yang sangat kompleks dan belum banyak diketahui dengan pasti. Kecenderungan fauna tanah untuk memilih suatu habitat dipengaruhi oleh beberapa faktor lingkungan baik biotik maupun abiotik. Tujuan dari penelitian ini adalah untuk mengkaji kedekatan ekologis antara karakteristik tanah gambut yang didrainase untuk HTI A. crassicarpa dengan kelimpahan fauna tanahnya. Penelitian dilakukan di HTI lahan gambut  PT. Arara Abadi, Distrik Rasau Kuning, Kabupaten Siak, Riau.  Pengambilan sampel fauna tanah dengan metode pencuplikan contoh tanah yang berukuran 25 x 25 x 25 cm3, pemisahan fauna tanah dengan tanah dilakukan dengan menggunakan modifikasi corong barlese.  Parameter yang diamati adalah kelimpahan dan keragaman fauna tanah, kematangan gambut (C/N), kadar air gambut, dan kedalaman muka air tanah gambut. Untuk menilai kedekatan ekologis digunakan analisis hirarki.  Hasil penelitian menunjukkan bahwa kelimpahan fauna tanah tertinggi terdapat pada tegakan A. crassicarpa umur 2 tahun. Keragaman jenis fauna tanah di lokasi penelitian termasuk melimpah sedang dengan nilai H’ 1,2. Formicidae berpotensi sebagai bioindikator kelembaban tanah gambut yang rendah yang dicirikan dengan kandungan kadar air yang rendah dan mempunyai tingkat kematangan gambut yang lebih tinggi. Entomobryidae berpotensi sebagai bioindikator kadar air yang tinggi dan mempunyai tingkat kematangan yang masih rendah. ABSTRACTManagement of peatlands for HTI cultivation of Acacia crassicarpa begins by making drainage ditches and land clearing, followed by the preparation of land for planting. As for the maintenance activity, it includes weed control using herbicides and fertilizer. Management and maintenance activities certainly have implications for the ecological condition of peatlands, where the changes in ecological conditions due to land conversion will impact the abundance and diversity of soil fauna. Abundance and diversity of soil fauna and ecosystem function showed a very complex relationship not widely known this far.  Soil fauna tendency to select certain habitat is affected by several ecological factors, both biotic and abiotic. The study aims to assess the ecological proximity between the characteristics of peatland drained for HTI cultivation of A. crassicarpa and the abundance of soil fauna. The study was conducted in HTI peatlands of PT. Arara Abadi, Rasau Kuning District, Siak Regency, Riau. Soil fauna sampling was conducted by taking soil sample of 25 x 25 x 25 cm in size.  Separation of soil fauna from the soil was performed by a modification to a barlese funnel. Observed variables were the abundance and the diversity of soil fauna, peat maturity (C/N), water contentof peatand ground water table.  For observing ecological proximity, hierarchical analysis was used.  Result showed that the highest of soil fauna abundance was found in A. crassicarpa stand, 2 year’s old of age. The species diversity of soil fauna in research location included as medium abundant by H’ value 1,2. Formicidae was potential become a low level-humidity bioindicators of peatsoil, which described by those pattern : low water content and higher level of peat maturity. Entomobryidae was potential become a high water content  bioindicator and low level of peat maturity.

Abstract

ABSTRAKPembangunan hutan tanaman di lahan gambut tidak terlepas dari sorotan isu negatif lingkungan terkait dengan penurunan kedalaman muka air tanah, sehingga terjadi perubahan ekosistem asli. Kegiatan reklamasi lahan untuk HTI Acacia crassicarpa dalam jangka panjang disinyalir akan menimbulkan dampak negatif terhadap perubahan karakteristik tanah gambutnya seperti tingkat kematangan dan laju penurunan permukaan tanah gambut (subsiden). Kajian mengenai dampak pembangunan HTI di lahan gambut terhadap tingkat kematangan dan laju subsiden perlu dilakukan untuk memberikan informasi mengenai kondisi exsisting daya dukung lahannya. Penelitian ini bertujuan untuk mengevaluasi tingkat kematangan gambut baik secara vertikal (berdasarkan kedalaman gambut) maupun secara horizontal (berdasarkan jarak dari bibir kanal) dan mengetahui laju subsiden sebagai dampak dari reklamasi lahan gambut menjadi HTI A. crassicarpa. Penelitian dilakukan di PT AA, Distrik Rasau Kuning, Kabupaten Siak, Riau. Plot penelitian ditempatkan dalam satu transek sepanjang 100 m yang dibuat tegak lurus dengan kanal tersier, terdapat 12 plot dan dalam satu transek terdapat 3 titik pengamatan sehingga total titik pengamatan adalah 36 titik. Parameter yang diamati adalah dinamika kedalaman muka air tanah, nilai kadar serat tanah gambut dan laju subsiden. Hasil penelitian menunjukkan bahwa dampak perubahan kedalaman muka air tanah gambut di lokasi penelitian hanya mempengaruhi tingkat kematangan gambut pada kedalaman kurang dari 2 m, sedangkan jarak kanal tersier sebesar 125 m tidak berpengaruh secara nyata terhadap tingkat kematangan gambut. Pada kedalaman kurang dari 2 m tingkat kematangan gambut lebih tinggi dibandingkan dengan lapisan di bawahnya. Pembangunan HTI A. crassicarpa di lokasi penelitian menyebabkan laju subsiden sebesar rata-rata 5,5 cm/tahun. ABSTRACTThe establishment of forest on peat areas is insepatable from the glare of the negative environmental issues associated with a decrease in the depth of water table which then result in a change of the original ecosystem. Long-term land reclamation activities for HTI Acacia crassicarpa is supposed to give a negative impact on changes in the peat soil characteristics such as level of maturity and the rate of decrease in surface peat soil (subsidence). Studies on the impact of HTI development in peat areas particularly on the level of maturity and rate of subsidence need to be done in order to provide information regarding the carrying capacity of the land exsisting condition. This study aims at evaluating the maturity level of the peat either vertically (based on the depth of peat) or horizontally (based on the distance from the lips of the canal) and determining the rate of subsidence as a result of reclamation of peatlands into plantations A. crassicarpa. The study was conducted in PT. AA, Rasau Kuning District, Siak, Riau. Research plots were placed in a 100 m long transects that were perpendicular to the tertiary canal. There are 12 plots and, transects consist of 3 observation points, so the total observation point is 36 points. Parameters measured were the dynamics of groundwater depth, the value of peat fiber content and the rate of subsidence. The results show that the impact of changes in the water table depth of peat soil in the study area only affects the level of maturity of peat at depths less than 2 m, whereas the tertiary canals distance of 125 m did not significantly affect the level of maturity of peat. At a depth of less than 2 m of peat maturity level is higher than the layer below it. A. crassicarpa plantation development in the study area leads to subsidence rate by an average of 5.5 cm / year.
