Corn production in Indonesia is quite high, namely 18,364,430 tons with a total harvest area of 4,131,676 ha and productivity of 41.18% (BPS, 2010). One type of corn that is potential and widely developed is pulut corn. This type of corn is very suitable in making corn chips because it has a high amylopectin content (> 80%). Pulut corn chips are produced by many small to medium scale industries as snack food products. The problem that then occurs is the handling of post-production, corn chips have a high ability of water absorption so that when fried, it does not bloom perfectly so that it is less tasty to consume. The aim of this research is to test the sorption isotherm equations of corn chips that provide the approximate balance of water content that is closest to the measured equilibrium water content. By using temperatures of 25°C, 30°C and 35°C with a combination of 40%, 60% and 80% RH, this study shows that the Henderson equation provides an estimate of the behavior of isotermic soring sorut corn chips that is at a temperature condition of 30°C closer to the results experiment and also at a temperature of 35˚C. Whereas the Chung & Pfost equation best describes the behavior of isothermic absorption at 25OC. In addition, this study also aims to determine the fragility (fracture) of pulut corn chips in various storage conditions. Research shows that the higher the RH environment, the higher the fracture value.

Clove (Syzygium aromaticum), belongs to the Myrtaceae family and is one of Indonesia's native spice plants originating from the Maluku Islands. Clove post-harvest handling at the farm level is still done manually, one of which is the separation of flowers from the stems that are still using their hands. Flowers and clove stems need to be separated because they have different prices and qualities. The purpose of this study was to determine the attachment of cloves to their stems and physical characteristics (dimensions, weight and moisture content) of clove flowers in the varieties of Zanzibar, Si-Putih and Si-Kotok. Adhesiveness is intended as the force needed to release the clove flower from the stem so that it can be a reference and basic reference in the design of the clove flower separator from the stem or other processing equipment. This study used samples of clove flower varieties of Zanzibar, Si-Putih and Si-Kotok based on the color of the flower (level of maturity). The results of this study indicate that the adhesiveness of the clove Si-Kotok variety is 0.22 kg, the Zanzibar variety is 0.17 kg and the Si-Putih variety is 0.15 kg. In terms of color, the adhesiveness of red clove flowers is 0.22 kg, red green is 0.17 kg and green is 0.16 kg. The adhesiveness of cloves does not have a consistent correlation with the parameters of the physical properties of cloves.

Sustainable groundwater extraction can be achieved if there is a balance between the amount of groundwater extracted and recharge. The ability of aquifers to release groundwater that affects groundwater extraction and recharge depends on aquifer characteristics. Therefore, aquifer characteristics need to be known so that the amount of extraction does not exceed groundwater recharge. This study aims to determine the position, thickness, type, specific yield and hydraulic conductivity of aquifers and identify catchment areas as sources of groundwater and groundwater potential. This research was conducted by interpolating lithology data and measuring aquifer hydraulic conductivity by pumping test methods. Hydraulic conductivity values were processed using Solver Add Ins in Microsoft Excel to get optimal conductivity values. The source of groundwater recharge was predicted based on a flownet of groundwater surface contour data and groundwater potential calculated using the Darcy’s approach. The results showed that the hydraulic conductivity in the study area was 16.13 m / day, the specific result was 0.32 with aquifer in the form of sand. Based on the flownet, the source of recharge comes from the western side of the watershed which flows eastward with a potential of 14,517 m3 / day ≈ 168.02 lt / sec.

Bantimurung watershed is the resource of irrigation water for the surrounding communities and the last few years the change in the magnitude of the maximum discharge and the minimum discharge fluctuates considerably. This study aimed to predict the flow discharge and investigate the validity of HEC-HMS model (Hydrologic Engineering Center's Hydrologic Modeling System) in predicting the flow discharge in the Bantimurung watershed of Maros Regency. The method used in this study was a quantitative method which included data collection of the research data in the field, such as rainfall data, discharge flow rate, soil texture and land use as well as the characteristics of Bantimurung watershed. Data analysis was done using HEC-HMS software. This software performed empirical simulation using rainfall, land slope, land use, soil physical characteristics and generate predicted discharge flow rate. The HEC-HMS model was calibrated using data from Public Work (PU) which were collected in 2006. The calibrated model was then validated using 2014 data. The calibration and validation results indicated that the predicted data were in good agreement with measured data R2 and NSE value of 0,546 and 0,595 respectively from the calibration process and 0,512 and 0,490 from the validation process. These results suggest that the HEC-HMS model can predict the measured discharge flow rate adequately
