Dam is one of the essential man-made buildings which was developed to various beneficialy purposes such as irrigation, fresh water supply, flooding and drying control, and also tourism. Due to those mentioned functions, condition of the dam has to be maintained continuously especially from sedimentation. Sedimentation is being a serious threat for the continuity of dam services. Protecting dam from sedimentation is not only managing dam area, but also we have to care all watershed area, because the sedimentation is caused by erotion on the area. In order to know the rate of the sedimentation within the dam, measurement and prediction must be done. One of methods to predict and measure the sedimentation is by analyzing geospatial data using USLE Approach, and analyzing suspended sediment in river’s water toward to the dam. By those both analysis, rate of sedimentation happened within the dam can be calculated. This paper try to use geospatial (GIS) based analysis to estimate the sedimentation rate using USLE approach within Ngrancah Watershed. The USLE Formula requires four types of maps, they are soil type, slope, land cover, and rain erosivity maps. Each of maps is classified to the specific standards, then will be analized by overlaying to another map. Another method will be used to estimate these dimentation rate is the suspended sediment measurement. This method was determined using sediment transport formula. The data used are samples of river water ing Ngerancah Watershed that was flow toward to the Sermo Dam, and daily volume of inflow water. Those resulted values, then were compared each other. Based on the calculation, sedimentation rate resulted using USLE Approach is 276.100,917 m3 per year or 8,675 mm thickness per year. While the calculation based on the measurement of suspended sediment in river’s water is 270.206,363 m3 per year or 8,490 mm thickness per year. The difference value between the both methods is 5894,555 m3 per year or 0,185 mm thickness per year. Based on the watershed monitoring guidelines published by The Ministry of Forestry of Indoensia, the Sermo Dam sedimentation rate is categorized in poor class, because the sedimentation rate is exceeding 5 mm per year, as the safe limit of dam sedimentation rate.

Obesity is not concerned as specific congenital disorder or derived lipid metabolism disorder recently, but more to bod yinability to handle the increase of nutrition intake caused by behavioral changes. Langerhans Islet is a section in the pancreas which play crucial role in producing and regulating metabolism hormones, insulin and glucagon. This research was conducted to observe blood glucose and lipid profile and to visualize Langerhans Islet in rat pancreas which were induced obesity and compared it with normal ones. Ten of male non-genetic obese four weeks old Winstar rats were divided into two groups, normal (K) and induced with obesity (O). Blood plasma samples were collected to determine blood glucose and blood lipid profile. Pancreas (regio splenic) samples were collected and fixated with Bouin solution, blocked by paraffin and cut with 5 μm thickness. Histology preparats were stained with Hematoxylin-Eosin and Immunohistochemistry (IHC) is determined with Labeled Sterptavidin-Biotin (LSAB) method. Staining is act as visual detector with will be analyzed descriptively and quantitatively. The data of Obesity group showed that blood glucose level is 88.59 ± 1.77 mg/dl, blood cholesterol level is 160.62±3.52 mg/dl, triglycerides level is 98.61±2.66 mg/dl, HDL level is 44.68±2.25 mg/dl and LDL level is 67.51±1.81. Pancreas’s topography in obese group spread into three regions, which are: gastrium, duodenum and lien. Langerhans Islet morphology shaped oval and polygonal also surrounded by fine filaments and blood capillary. Insulin and glucagon immunoreactive cell’s morphology in obesity group shaped irregular polygonal with round/oval nucleus placed in central/peripheral. Langerhans Islet’s in obesity group has diameter (154.38±65.56) μm, circumference (373,51±146,69) μm and volume 3241105.96 μm3. Obesity induced rat showed the increase in cholesterol level, triglycerides level, LDL level, blood glucose level and Langerhans Islet’s diameter, volume and circumference compared to normal ones (P<0.05). Decrease of HDL, topography and morphology of pancreas in obesity induced rat did’t showed significant changes compared to normal ones.

Cocoa powder is usually used to be a raw material in the chocolate products. In the large scale production, cocoa powder must be stored at specific time period before it was used. The quality of cocoa powder can decrease during storage period hence shelf life analysis of cocoa powder is needed. The aim of this study was to determine the shelf life of cocoa powder by Accelerated Shelf Life Testing (ASLT) Method with Arrhenius Model Approach. Cocoa powder was stored at different temperature (30, 40, and 50oC) and different packaging type (plastic with zipper and paper craft with zipper) to simul atedacceleration of damage as a result of temperature increase. Cocoa powder contained high level of fat so it more easily gone rancid. Moisture content and peroxide value were observed periodically that shown the quality parameters of cocoa powder. Initial moisture content and fat content of cocoa powder were analyzed by gravimetric method. Degree of rancidity which was shown with peroxide value was analyzed by iodometric titration method. According to the change of peroxide value, the shelf life of cocoa powder can be estimated.

Monitoring of deformation on Sermo Dam has been widely practiced. One of them is by installing the monitoring point, locate dinside the Sermo Dam area called the micro network, and outside the dam called macro network. The installation of the micro network monitoring point aims to monitor the deformation of the dam due to the volume of water. The macro network monitoring point aims to monitor the effect of the existence of an active fault under the dam. In the last few years, monitoring in Sermo Dam has been done using GNSS technology. This paper intends to present the results of the accuracy represented by the deviation standard value of the measurement point at the macro net on the GNSS observation in 2016 and 2017. The objective is to compare the accuracy resulting from various GNSS processing strategies in observation 2016 and 2017, evaluation of GNSS measurements that can be used as guidance in subsequent GNSS measurements. The result shows that GNSS measurement in 2017 using two IGS reference points (BAKO and COCO) has a better standard deviation value compared to the 2016 measurement by the difference 1-5 mm on the X axis, 1-9 mm on the Y axis, and 1-2 mm on the Z axis. In the GNSS data processing using seven IGS reference points (BAKO, COCO, KARR, DARW, GUUG, PIMO, SHAO) in 2016 mostly has a better standard deviation compared to 2017 measurement except in MAK5 with the difference 0-4 mm on the X axis, 1-10 mm on Y axis, and 0-2 mm on Z axis. As for the value of coordinate data processing in 2016 and 2017on the two processing strategies there are differences in coordinate values that indicate the movement of monitoring points of macro network. However, the vector of the point movement that occurs in the two strategies has a different direction. This requires verification in-depth research and focused on the deformation of the Sermo Dam monitoring point.

Indonesia has large area of marginal land including coast sandy soil and post coal mining soil areas. Reclamation process for marginal land needs long time and high cost, hence, strategic treatments are necessary to reduce both time and cost. This research aims to analyze the effects of media (coast sandy soil, alluvial deposit, and post coal mining soil) and legume over crop Centrocema pubescens on the growth of mahogany seedlings. This research was conducted at green house for 3 months using Completely Randomized Design (CRD) with 3 x 2 factorials and 3 replications. The first factor was marginal soil (three levels: coast sandy soil, post coal mining soil, and alluvial deposit as reference) while the second factor was the application of legume cover crop (two levels: apply and not apply). Variables observed were the height, diameter, biomass, and nutrient content of mahogany seedlings. The results showed that the growth of mahogany in sandy soil media is the best though nutrient content in that media is the lowest. It was caused reduction of salinity from that media. While, up to 3 months old, C. pubescens grew competitively.

Spatial data is a very important role in emergency command and disaster management, before, during or post disasters. When a disaster occurs, the currently geospatial information is very needed: where the center of the disaster, the area affected, the volumetric of the landslide, what facilities are damaged, and determine the location of temporary shelters. This study examines and analyze the landslide in Banjarnegara 2014 before and after the landslide using Peta Rupa Bumi Indonesia (RBI) and the UAV Aerial Photos (Unmanned Aerial Vehicle). Data before the landslide obtained from RBI, while data after landslide obtained by performing aerial photography using fixed-wing UAV in December 2014 and August 2015. These aerial photos processing with photogrammetry to produce digital orthophoto and DEM (Digital Elevation Model). Orthophoto and DEM data is used to perform geospatial analysis in both 2D and 3D. 3D analysis obtained from the extraction of DEM elevation map data values appearance of the earth (RBI) and the UAV Aerial Photo. Analysis was conducted on the four components: contouring, terrain profile/cross section, slope/gradient, and volumetric (cut and fill). Readiness management of geospatial data and information is necessary to minimize losses and speed up the process of rehabilitation and reconstruction in the areas affected by the disaster. With this spatial analysis, the estimated of volume of landslides, mapping the facility affected, and the manufacture of the soil profile (high landslide, landslide affected area) can be performed quickly and accurately.
