Regional development can be carried out with an emphasis on the basic sectors and leading commodities. The purpose of this study is twofold. The first is to determine the basic sectors, sub-sectors, and leading commodities, and the second is to analyze the suitability and allocation directives of land for leading commodities. The data used include gross regional domestic product (GDP) of West Java and the harvested area in 2011-2013.The other data are land suitability requirement, map soil types, rainfall, temperature, grade slope, erosion, map of soil units, land use, spatial plans, and administrative maps. Location Quotient (LQ) method is used to determine the basic sectors and sub-sectors. Meanwhile, the LQ and Differential Shift and Share are used to determine the leading commodities. The land suitability of leading commodities is spatially analyzed using Geographical Information System (GIS). The results have shown that the agriculture is the basic sector and food crop agriculture is and the basic sub-sector. The leading commodities are soybean, peanut, and rice. The land suitability classes are S2 and S3. The available allocation areas are 27.984 Hectares for wet-field paddy, 17.984 Hectares for peanuts, and 38.835 Hectares for soybean.

Land carrying capacity is important to be considered in spatial planning. This study was aimed to evaluate the land carrying capacity of the spatial planning of Blitar Regency using land capability evaluation. Evaluation was done by assesing the conformity between the actual land utilization and land allocation of the Official spatial planning of Blitar Regency toward the land capability. The class of land capability was evaluated for each land unit, which was combined from landforms and soil survey from the previuos research. The actual land use analysis was done by updating land use maps that have been provided by the SPOT-6 images acquired in 2015. The result showed that land capablity in Blitar Regency was consist of class II, III, IV, VI, VII and class VIII. The area with land capablity class of II to IV which supported agricultural cultivation were only 39.0% of total area, meanwhile 61.0% of total area should not be used for agricultural cultivation (class VI to VIII). The actual land carrying capacity based on the conformity between the actual land use and land capability were only 69.662 ha (43,8%), while the land carrying capacity of planning aspect based on the conformity between the official spatial planning and land capability was reached 79.498 ha (50,0%).

A sensitivity analysis of SWAT parameters was conducted on different spatial resolutions. The sensitivity analysis aimed to determine the input parameters that have the most impact on the of output of the model. Resolution of different inputs in the SWAT analysis can produce different input parameters that can affect the output. The purpose of this study was to identify the level of sensitivity of the parameters used in the SWAT model simulated on two different resolutions, i.e. 1: 100,000 and 1: 250,000. A sensitivity test was conducted manually using the absolute sensitivity method, i.e. a method to test the sensitivity of the parameters of SWAT model that can change (either increase or decrease) one by one while the other parameters are constant. The results show that the Nash-Sutcliffe Efficiency (NSE) coefficients derived after calibration of the SWAT models on both resolutions of maps indicate similar performance of the models, with the category for the daily simulation of excellent (NSE coefficients of 0.55 and 0.54), while the monthly simulation is categorized as very satisfactory (NSE coefficients of 0.80 and 0.82). The sensitive parameters of the SWAT model identified in the current study include CN2 (initial SCS runoff curve number for moisture condition II), Alpha_BNK (flow recession constant or recession proportional to the banks of the river), CH_K2 (effective hydraulic conductivity in main channel alluvium), CH_N2 (Manning’s “n” value for the main channel), ESCO (soil evaporation compensation factor), GW_Delay (groundwater delay), and GW_Revap (groundwater “revap” coefficient).

Land use changes from forest to non forest on a large scale causing environmental damage and decrease the hydrologycal function of a watershed. The problem of forest change can be reduced by identifying, assessing and mapping of high coservation value areas based on requirements that led an area to be important outside the protected areas. This study was conducted at Ciliwung Upper Watershed. The aim of the research were identify the high conservation value areas base on environmental services aspect with erosion and sedimentation control (HCV 4.2), and b) analyze the consistency of HCV 4.2 to land capability class and Goverment Rule No 26 year 2008. The RUSLE equation to identify the area of HCV 4.2 is modified in HCV Toolkit that ignore the land management and conservation practice aspect. Land capability is classified base on Klingibel and Montgomary, but there are just 4 criteria which is used in this research (erosion, slope, depth of solum, and drainage). The result showed that 90% of total area of research was identified as area of HCV 4.2. There are 7 class of land capability (class I, II, III, IV, VI, VII and VIII) where the class IV and VIII are dominant in the area. From consistency analysis, it is known that 75% of area of HCV 4.2 is inconsistent with land capability class and Goverment Rule No 26 year 2008.

The research is aimed to analyze leachate, surface water and ground water characteristics around Galuga landfill site, Bogor District. Water samples had been taken in dry season of 2014 and in the end of rainy season of 2015 from several sites in areas around Galuga landfills which included leachate water, surface water, and ground water. Leachate, surface water and ground water had temperature and pH in normal ranges; whereas nitrate and Pb contents were high to very high levels, especially in site adjacent to waste piles. The concentrations decreased in line with increasing distance from waste piles. Higher content of nitrate in leachate occurred in dry season, but in well water it was found in rainy season. Meanwhile, Pb content in well water were high, both in dry and rainy seasons. Concentrations of nitrate and Pb in leachate water were higher than wastewater quality standard, so that the leachate water were not safe to be discharged directly to natural water body. The high content of nitrate and Pb caused the well water unsuitable to be consumed without water treatment processing.

Pemerintah berencana membangun embung sebanyak 30.000 pada tahun 2017. Embung merupakan salah satu metode konservasi tanah dan air untuk menurunkan aliran permukaan, meningkatkan retensi air permukaan dan meningkatkan air yang masuk ke dalam tanah (infiltrasi), yang berakibat langsung terhadap nilai Koefisien Regim Aliran (KRA) atau Koefisien Aliran Tahunan (KAT) suatu DAS. Penelitian tentang pengaruh embung dan kombinasinya dengan teknik konservasi tanah dan air lainnya (strip cropping dan agroforestri) terhadap KRA dan KAT pada DAS Cilemer dengan menggunakan metode SWAT ini dilakukan tahun 2017. Hasil penelitian menunjukkan bahwa Skenario 1 (teknik KTA embung) mampu menurunkan KRA dan KAT masing-masing sebesar 25.45% (dari 119.70 menjadi 94.25) dan 32% (dari 0.25 menjadi 0.17). Skenario 2 (teknik KTA gabungan antara embung dan strip cropping) mampu menurunkan KRA dan KAT masing-masing sebesar 40.92% (dari 119.70 menjadi 78.78) dan 32% (dari 0.25 menjadi 0.17). Sementara Skenario 3 (gabungan teknik KTA embung dan agroforestry) mampu menurunkan KRA dan KAT masing-masing sebesar 41.38% (dari 119.70 menjadi 78.31) dan 36% (dari 0.25 menjadi 0.16). Penerapan embung beserta kombinasinya dengan teknik KTA lainnya mampu menurunkan KRA dan KAT secara cukup berarti.Kata kunci: Agroforestri, embung, koefisien aliran tahunan, koefisien rejim aliran, strip croppingDOI: http://dx.doi.org/10.7454/jglitrop.v2i2.45

Rachman LM, Baskoro DPT, Wahjunie ED, Nurmilah A, Astriani T, Dewi NM. 2019. Evaluation of the physical properties of controlling soil capabilities holding water and supplying water for plants and its association with agricultural management on sub-optimal lands. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal 2019, Palembang 4-5 September 2019. pp. 111-120. Palembang: Unsri Press. Utilization and optimization of marginal land or sub-optimal land is needed to support the government's food security program. Rainfed sub-optimal land, although quite extensive (2,247,527 ha) and still potential enough to be utilized. However, the current low productivity due to a variety of biophysical constraints, required input and recommendation technology appropriate land management to increase productivity. Sub optimal rainfed land including dry land. One serious obstacle faced is often experiencing water shortages or droughts during the dry season. However, the current low productivity due to a variety of biophysical constraints, required input and recommendation technology appropriate land management to increase productivity. Sub optimal rainfed land including dry land. One serious obstacle faced is often experiencing water shortages or droughts during the dry season. The lack of water in the plant root zone can basically be caused by: 1) lack of water supply, 2) low soil capacity to hold and supply water for plants, or 3) a combination of both. For this reason, it is necessary to have accurate and comprehensive data and information about the ability or capacity of the soil to hold and store soil water holding capacity. The purpose of this study is to examine the characteristics of physical properties of land in sub-optimal land that controls the ability or capacity of the soil to hold or hold and store water so that directions can be arranged for agricultural management in sub-optimal lands to increase productivity. The location of the study whose data was reviewed in this study included the areas of Bogor, Lebak, Pandeglang and Serang. Some of the soil physical properties studied were soil bulk density, soil texture, stability of soil aggregate stability index, total soil porosity, distribution of soil pores, and soil organic matter content. Evaluation results indicate that in general the characteristics of the physical properties of the soil associated with its ability to supply water are available to plants and hold and store water are classified as moderate. Directions for recommendations for processing and managing soil for agricultural management are adjusted to the conditions and characteristics of the soil.Keywords: agricultural management, land management, soil physical properties, sub- optimal land, soil water holding capacity

The concept of sustainable development is very important to increase our quality of life. Measurement of development based on specific indicators is one of the approaches to describe sustainable development. At the local level, measuring sustainable development using specific indicators is still rare. Since each location has their own unique characteristics, measuring sustainability at the regional level could not always be applied locally. The availability of data at the village level strongly encourages the local measurement of sustainable development index. The economic, social, and environmental dimensions of Mandailing Natal Regency's development are still constrained. Using 21 variables that can reflect economic, social, and environmental aspects, this study aims to measure the sustainable development index at the local level. The Local Sustainable Development Index will be generated by analyzing these variables using the Factor Analysis (FA) method and Local Indicator of Spatial Autocorrelation (LISA) analysis. This index measurement is useful in considering the direction of location-based (spatial) development for decision makers at the local level and describe development sustainability. In general, IPBL economic value was in the medium category in 2011, and several villages in the low category were able to enhance their economic development sustainability in 2018. In the northwest, IPBL environment cluster type High-high (HH). In 2018, the percentage spatial distribution pattern of villages with the Low-low (LL) cluster type of IPBL economic and IPBL environment decreased. However, as can be seen from the spatial distribution pattern of IPBL social with cluster type LL, the percentage increased in 2018.

Clove is a scented dried flower stalk from the Myrtaceae tree family. Farmers in Paninggaran Village experienced a problem, namely a decrease in clove production and even crop death. Dead molt is one of the diseases that are affected by clove plants and is related to the cultivation carried out by farmers in treating clove plants. Therefore, it is necessary to do a rapid assessment and checking to identify diseases in cloves and provide an explanation to farmers regarding symptoms and efforts to overcome this problem. The purpose of the rapid assessment and clove inspection activities is to analyze the knowledge, attitudes and actions of farmers in clove cultivation and to find out the right solution that can be done as an effort to respond to the incidence of molting on cloves. The method used is interviews and direct observation. Interviews were conducted with 9 farmers with direct observation of 20 clove trees. The result of this activity is the use of organic fertilizer by farmers still needs to be increased. Percentage of trees showing symptoms of stem and twigs by 4%, while trees showing symptoms of stem cancer by 96%. Farmers replace their commodities into tea as a solution so that the borers do not attack again. Knowledge, attitudes and actions of farmers in clove cultivation still need to be improved in order to minimize the negative impacts that will occur. Keywords: borers, clove cultivation, farmers, molt death, rapid assessment
