Abstract

ABSTRACTDesignation of forest area in Bangka Island region, Bangka Belitung Province according to Kepmenhut 357/Menhut-II/2004 has provoked a conflict between the various interested parties. Boundary demarcation process as the next stage from designation forest area had a conflict with local communities. This study had purpose to identifylanduse and landcover condition of forest area and the type of conflict. The applied methode was image intepretation and classification and alsoRaTA (Rapid Land Tenure Asessment). The study showed that landuse and landcover condition was dominated with grassland and the form of occupied local people is cropland, palm oil plantation, open field, and the settlement. Tke kind of conflict in the field study was strugle of access and withdrawall rights of land resources in the forest area that causes by different persepsion between local peoples and the Goverment as the parties has management and demarcation boundary authorithy of forest area with the problem is illegal activity and land convertion from other use area into forest area. Forest Management based by The Community would be ideal conflict resolution and those need the socialisation, intensive and effective communication between the parties that had a conflict.Keywords: forest land tenure conflict, landuse and landcover, conflict resolutionABSTRAKPenunjukan kawasan hutan di wilayah Pulau Bangka Provinsi Kepulauan Bangka Belitung berdasarkan Keputusan Menteri Kehutanan Nomor 357/Menhut-II/2004 menimbulkan konflik bagi para pihak yang berkepentingan. Proses penataan batas sebagai tahapan berikutnya dari penunjukan kawasan hutan mengalami penolakan dan konflik dengan masyarakat lokal. Penelitian ini memiliki tujuan untuk mengetahui kondisi penutupan dan penggunaan lahan kawasan hutan serta tipe konflik yang terjadi melalui intepretasi dan klasifikasi citra satelit serta analisis RaTA (Rapid Land Tenure Asessment). Hasil penelitian menunjukkan bahwa kondisi penutupan lahan wilayah penelitian didominasi oleh semak belukar dan bentuk okupasi lahan masyarakat berupa lahan terbuka, kebun sawit, kebun campuran dan pemukiman. Tipologi konflik yang terjadi lebih kepada konflik perebutan hak akses dan hak pengelolaan sumber daya lahan yang terdapat di dalam kawasan hutan yang disebabkan karena perbedaan persepsi antara masyarakat dengan Pemerintah sebagai pemegang wewenang pengelolaan dan penataan batas kawasan hutan dengan bentuk permasalahan berupa perambahan kawasan hutan dan adanya alih fungsi lahan dari Areal Penggunaan Lain (APL) menjadi kawasan hutan. Program Pengelolaan Hutan Berbasis Masyarakat (PHBM) menjadi resolusi konflik yang ideal dan perlu dilakukan sosialisasi dan komunikasi yang intensif dan efektif antar para pihak.Kata kunci: konflik penguasaan lahan, penutupan dan penggunaan lahan, resolusi konflik

Abstract

Crop and management factor value is significantly corelated with outputs of ANSWERS model especially on soil erosion.   Using daily crop and management factors (daily C factors), the ANSWERS model performs well in predicting soil erosion which is showed by determination coeffient (R2 = 0.89), model efficiency (0.86), and average of percentage model deviations (24.1 %).  Whereas using USLE C factor (2 cropping systems), predicted is much higher than measured soil erosion (over estimate).  Output of the model is not statisfy, it is represented by model coefficient (0.40) and average of percentage model deviations (63.6 %).

Abstract

Way Betung watershed is one of the important water resources in Lampung Province and it provides a clean water for Bandar Lampung City through a regional water supply company (PDAM). By the increase of population and economical activities of Bandar Lampung City, the need of clean water also increase, however by the time, the conditions of Way Betung watershed as water resources are declining. Therefore, to improve or to restore WayBetung watershed, a high cost is needed. The research was aimed: (a) to study the effects of Way Betung watershed land use change on the water resources of Bandar Lampung City, (b) to arrange the sustainable development of Way Betung watershed in order to maintain the availability of water resources. The sustainable developments of water resources of Way Betung watershed were arranged in five alternatives/scenarios and each alternative was related toits erosion (USLE method) and its run off volume (SCS method). The results showed that land use changes of Way Betung watershed (1991-2006) were likely to increase daily maximum discharge (Q max), to decrease daily minimum discharge (Q min), to increase fluctuation of river discharge, and to increase yearly run off coeffcient. The best sustainable development of water resources of Way Betung watershed, Lampung Province, was alternative/scenario-4 (forest as 30% of watershed areas + alley cropping in the mix garden). This alternative will decrease erosion to the level lower than tolerable soil loss and also decrease fluctuation of monthly run off.Keywords: Land use change, run off coefficient, water resources, watershed

Abstract

The study was aimed to quantify volume of surface runoff, soil erosion and nutrient loss from the forest-agriculture landscape (forest margins) in Lore Lindu National Park Central Sulawesi.  Surface runoff volume and soil erosion were measured daily on erosion plots. It was installed on  several land use types i.e. forest land,  maize,  young cocoa, medium cocoa, old cocoa, vanilla, shrub and bush and bareland, on the soil Typic Dystrudepts with slope ± 40%. The nutrient content in surface runoff and sediments were analyzed from selected surface runoff and sediment samples.  Surface runoff and soil erosion from agriculture land were respectively 2.1 to 3.4 and  3.6 to 5.8 times higher than from forest lands. Meanwhile, surface runoff and soil erosion from bareland were respectively 7.0 and 23.7 times greater than forest land respectively.  Sediment nutrient contents from forest land were  higher than agriculture land.  In the contrary, total nutrient lost from agriculture land were higher than forest land ones.  Nutrient losses carried by surface runoff were larger than those losses carried by sediments.  Dissolved organic carbon (DOC) loss in surface runoff was 6,1 to 8,0 times higher than total organic carbon (TOC) loss in sediments.  Likewise, nitrate (NO3-) loss in surface runoff was 1.9 to 12.1 times higher than total nitrogen (TN) in sediments as well as potassium, calcium, magnesium and sodium losses.  Potassium is dominant cation loss carried by the surface runoff, while calcium is mainly carried by sediment.Keywords:  Dissolve organic carbon; forest-agriculture landscape; nutrient loss; soil erosion; surface runoff[How to Cite: Hidayat Y, K Murtilaksono and N Sinukaban. 2012.

Abstract

Effort to Increase Oil Palm Production through Application Technique of Soil and Water Conservation (K. Murtilaksono, W. Darmosarkoro, E.S. Sutarta, H. H. Siregar, and Y. Hidayat): The study was carried out at block 375, 415, and 414 (block 1, 2, and 3) Afdeling III, Mangement Unit of Rejosari, PT Perkebunan Nusantara VII, Lampung from June 2005 until December 2007.  Objective of the study is to examine the effect of soil and water conservation measurement, namely bund terrace and silt pit that are combined with retarded-water hole on production of oil palm. Sampled trees of each block were randomly selected as much as 36 trees.  Parameters of vegetative growth (additional new frond, total of frond, number of new bunch), production (number of bunch, fresh fruit bunch (TBS)), and average of bunch weigh (RBT) were observed and recorded every two weeks.  Production of palm oil of each block was also recorded every harvesting schedule of Afdeling.  Tabular data were analyzed descriptively by logical comparison among the blocks as result of application of bund terrace and silt pit.  Although the data of sampled trees were erratic, bund terrace and silt pit generally increasing number of frond, number of bunch, average of bunch weight, and fresh fruit bunch.  Bund terrace gived the highest production of TBS (25.2 t ha-1) compared to silt pit application (23.6 t ha-1), and it has better effect on TBS than block control (20.8 t ha-1).  Aside from that, RBT is the highest (21 kg) at bund terrace block compared to silt pit block (20 kg) and control block (19 kg).

Abstract

Soil Nutrient are dynamics. Their amount and movement within soil solution can determine its fertility to accomodate plant growth. The dissolved nutrients are moving together in the form of cations and anions. This study aims to determine the amount of dissolved cation-anion in the soil solution and to evaluate its relationship. Field trial was conducted at tropical rainforest of Bukit Duabelas National Park. The Lisymeter was installed on each Typic Hapludult soil horizon to accommodate percolated water. The leached water sample was extracted and each cation (NH4+, Ca2+, Mg2+, K+) and anion (PO43-, Cl-, SO42-, NO3-) concentration were measured. Data were analyzed using independent-t stastical test, Spearman correlation, and stepwise linear regression. The results show that the total amount of cation and anion are significantly higher in the AO horizon than the AB and B horizons. The correlation analysis results show that each cation has a strong correlation to each anion (correlation value > 0.80) except PO43- ( ~ 0.70). Stepwise linear regression model shows that NH4+ has the strongest relation to NO3-, PO43-, and Cl- with R2 adj.= 0.75, Ca2+ to NO3-, PO43-, and SO42- (R2 adj.= 0.856), Mg2+ to NO3- and  PO43- (R2 adj.= 0.815), and K+ to PO43- and Cl-  (R2 adj.= 0.845). It can be concluded that NO3-, Cl-, SO42-, and PO43- are directly involved as cation co-pairing agents in the soil nutrient movement and leaching process.

Abstract

The Ground Water Level plays an important role in determining the greenhouse gas emission and, in turn, in regulating global climate system. Information on existing water levels is still using field measurements. The purpose of this study was to evaluate the best approximation model for estimating water level using drought index. This study utilizes Landsat 8 data to calculate Normalized Difference Water Index and Visible and Shortwave infrared Drought Index for 3 months (March, April and June 2016). The best estimation model is selected by the Akaike Information Criteria correction method and validated using K-Fold cross-validation. The results of this study indicate that the estimation of water level is affected by both drought indices with the TMA (mm) equation = -439,47 – 1639,7 * NDWI_Maret – 640,23 * NDWI_April + 477 * VSDI_Maret. Estimated water level began to detect hotspots ranging from 64,35 ± 36,9 6 cm (27 - 101 cm). The critical point for KHG Sei Jangkang - Sei Liong is 27 cm, thus the water level depth should be maintained less than that to avoid fire in peatlands.

Abstract

Disasters of forest and land fires are increasingly concerned. The nature of peat soil which is easy to lose water and high organic matter content causes peat soils to be very sensitive to fire. Therefore it is necessary to know indicators for early warning of fires on peatlands. The purpose of this study is to determine the critical groundwater level (GWL) as an indicator of peatland fires on the Jangkang River - Sungai Liong. Determination of the critical point of peatland fires as a fire early warning is done by calculating the difference from the value of the undefined TMA with a range of possible errors. The TMA value is obtained from the estimation of several methods, namely data on the physical properties of the soil, the drought index, and a combination of both. The TMA estimation of the physical properties of the soil has a range of fires at depths of 74.3 - 107 cm. In estimating TMA using a drought index, potential fires occur in TMA ranging from 27 - 101 cm. While the combined estimates of the physical properties of the soil and the drought index ranged from 66.8 - 98.8 cm the occurrence of fires on peatland. The results of this study show that the estimated TMA from a combination of field data and drought index provides fairly good accuracy. Thus TMA can be an early warning indicator of the danger of peatland fires. This TMA estimation can give faster results and pretty good accuracy. But this estimation model for TMA does not necessarily apply directly to other research locations. The critical point of peat soil water depth ranges from 27 to 74 cm. The depth of the peatland surface should be maintained less than the critical point, if not then the potential for peatland fires will increase.
