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

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

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).
