Published: June 2020

Abstract
Bogor is one of trading centers of salted fish for Bogor and surrounding areas. Salted fish products are marine fishery products that are salted and dried. Consumers like the products, but in the market, we could find harmful additives in them. The purpose of this research is to analyze the policy of salted fish supply chain from supplier to final consumer and formulate recommendation related to supervision and improvement of salted fish quality in Lawang Seketeng market, Bogor in order to assure that the salted fish products in the market are safe for people’s health. The results show that there are four types of salted fish products supply chain in Lawang Seketeng Bogor market. Based on the results analysis, it shows that the largest marketing margin does not mean the biggest profits for business actors. The choice of supply chain also depends on sales volume, lead-time, capital and warehouse capacity. The results based on confusion matrix also indicate that not all business actors could confirm the existence of dangerous additive content in their products. Based on SMiE-BAG model, monitoring and coaching system need to be implemented by the Bogor City Office of Industry in order to improve the safe supply chain performance for consumers.

Abstract
The number of corn production and consumption in Indonesia has increased every year. One of the activities in achieving the production target is by supplying high-quality corn seeds. The water content of harvested sweet corn was ranging from 60% to70%. In order to produce a high quality of seeds, drying should perform with a standard drying temperature for seeds which is between 38°C and 43°C. A performance test of a tray drying machine with an air dehumidifying process was conducted. The air dehumidifying process was conducted by an air conditioning system. Drying was carried out until the corn seeds reach 10-11% moisture content with observations every two hours. This drying machine provided lower relative humidity air drying than conventional sun-drying with a 75% relative humidity reduction from the environment. Therefore, drying with optimal temperature can be conducted faster and higher efficiency. The average dehumidified air temperature was 41.1±0.6°C and the average relative humidity was 15.9±0.7% was used for drying air. It took 44 hours 25 minutes to reach 11% of sweet corn’s moisture content while the sun drying process took 89 hours of drying. The seed germination could reach 85.7% by using this method which was a 1% difference from a sun-drying method which was 86.7%.

Abstract
Fertilization for maize plants so far does not use the appropriate calculation of crop needs, thus it causes continuous soil damage. Another technique to predict nitrogen content in maize plants is using a leaf color chart. But it has some disadvantages, such as depending on sunlight for color plant reading, and inconsistent accuracy interpretation of leaf color by the eye. Based on problems, the research was aim to design a nitrogen content prediction system based on digital images with an RGB color index. RGB digital image and nitrogen content are used as a database system to predict nitrogen need for maize plants. Arduino UNO is used for data processor and the TCS3200 color sensor is used as a substitute for a camera on image processing. The performance test uses 40 leaves of maize plants with the age of 15, 30 and 40 days. The results show that the device can detect nitrogen content in maize plants based on the RGB database with a 90% success rate. For R value 447,4-601,6, G value 384,7-510, and B value 519,95-625,16, we obtain that nitrogen need for plant about 175 kg/ha. For R value 325,9-377,5, G value 285,6-311,5, and B value 426,4-456,1, we obtain that nitrogen need for plant about 150 kg/ha. And for R value 290,37, G value 239,12, and B value 385,62, the nitrogen need for plant about 125 kg/ha. The greener the color of maize leaf, the lower the nitrogen fertilizer need, conversely the lower the green color on the leaf, the higher the level of nitrogen fertilizer needs.

Abstract
Efforts to study ecosystems have been carried out by humans since ancient times in various ways or approaches. The approach of using a computer model and simulation nowadays is one of the increasingly possible alternatives, especially with the rapid advancement of information and communication technology. There are several ways to build computer models of an ecosystem to be used in simulations. Composite modeling is one method that can be used where several computer programs (main, sub-routines, functions, sub-programs) written using a procedural programming language, which as a whole are integrated into one final program that can be run on a computer. The approach in this research is different from what was explained earlier. Composite models are still used but each component of the model is kept separate which is not combined into one module when the simulation process of the ecosystem model is formed. Each module remains separate but will operate side by side and communicate with one another through an auxiliary module to allow conditions to work (Molenaar, 1998). This research was conducted to make a prototype of a composite computer simulation infrastructure model of an ecosystem. The outputs of this research proved that the approach seemed working well and able to be used as computer simulation infrastructure in studying various existing system start your abstract here.

Abstract
The effectiveness of citronella oil distillers with one and two furnaces was studied. The parameters measured were the ability of the distiller to extract essential oils, distillation time, and the cost of the fuel used. The ability of the distiller to extract essential oils was measured based on the amount of essential oil produced. The distillation time was calculated from the time the distiller was operated until no oil was observed in the condensate. Fuel costs were calculated based on the amount of fuel used. The results showed that compared to single furnace distillers; two furnace distillers have faster and more effective extraction capabilities. The yield of citronella oil that could be extracted by distillers one and two furnaces was respectively 0.73 and 0.77%. Activation of the second furnace in the two-furnace distiller caused an increase in production costs of Rp.5416.67 for the distillation of 25 kg of raw material. The increase in production costs contributed to a decrease in processing time of 15.16% (from 296.33 to 257.33 minutes), an increase in the amount of oil that could be extracted by 5.44% (from 186.00 to 193.67 ml), an increase in effective capacity by 19.92% (from 37.66 to 45.16 ml / hour), and increased distillation effectiveness by 4.12% (from 85.52% to 89.04%).

Abstract
Computer technology has revolutionized the study of hydrological systems and management of water resources. Several computer-based hydrological models have been developed for applications in hydrological modeling and water resource studies. Geographic Information Systems (GIS) Interface models help create input data files, analyze and display results in a more efficient way. One interface GIS model available for water resources analysis is the Arc - Soil and Water Assessment Tool (ArcSWAT), a distributed parameter model developed by the United States Department of Agriculture. ArcSWAT has been applied, validated and calibrated for analyzing surface runoff in Air Dingin Watershed in Padang City - West Sumatra Indonesia. Validation was conducted to test the accuracy of the model in representing the real situation of the Air Dingin Watershed. Furthermore, calibration was performed to enhance the accuracy of the model. The results of ArcSWAT validation indicated that the Nash–Sutcliffe Efficiency (NSE) value was 0.12 and Coefficient of Determination (R2) was 0.4. After the calibration was carried out by changing the value of some parameters in the model, the NSE value becomes 0.68 and R2 becomes 0.66. This accepted model furthermore could be used to simulate water balance in the Air Dingin watershed.

Study of Tempe Production from Dried Peeled Soybeans
Authors: Hasbullah  , Silvy D 
Published: June 2020

Abstract
Soybean seeds that will be fermented into tempeh must be peeled by tearing the skin from soybeans that have been previously boiled and soaked in water (for 24-48 hours). Tearing apart causes the seed coat to separate and the seed cotyledon to separate into two. This method is called wet peel, which requires more water, time from energy to separate the skin from cotyledons. In this study, the processing of tempeh made from raw soy peel is dried. Soybeans to be peeled were treated with drying at 50, 60 and 70oC for 12 hours. Tempeh made from dry peeled soybeans compared to the quality of the sensor is tempeh made from raw wet peeled soybeans, and tempeh made from dried peeled soybeans whose soaking process is added with soybean skin. Dry stripping of soybeans that are dried at a temperature of 70°C will produce a better peel than soybeans that are not dried, or which are dried at 50 and 60oC. The yield is 82%, seeds are not peeled 1% and seeds are damaged 1%. However, dry stripping that is done twice on un-dried soybeans can produce peels that are almost as good as soybeans that are dried first at 70oC. This method is more efficient in terms of energy and time used to get dry peel seeds, the process of making tempeh from dried peeled soybeans will save water usage by 40% and time for washing soybeans after soaking as much as 50%. The sensory quality of tempeh made from dry peeled soybeans is the same as tempeh made from wet peeled soybeans as is commonly done by tempeh producers in Indonesia.
