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

Jackfruit has a short shelf life, can only last between 2-3 days at room temperature. Several ways can be done to maintain the shelf life of jackfruits, such as storage in the cold room, pressurized space, or modification of the atmosphere of the room. But this method requires expensive operational costs. The purpose of this study was to examine the effect of using aloe vera gel as an edible coating to be applied to the jackfruit. The study was conducted with the stages of making aloe vera gel as an edible coating, coating the edible coating on the sample, then the sample was stored at 10 and 29oC for 10 days. The research parameters observed were water content, texture, and color. The results showed that the water content of jackfruit could be maintained using an edible coating. The shelf life of jackfruit was longer stored at 10oC than stored at 29oC. The best edible coating results obtained on the treatment of aloe vera gel with a concentration of 0.5% CMC because it can inhibit the increase in water content, maintain texture, and the color of jackfruit is still like fresh fruit. To improve the results of this study, it is necessary to conduct further research by examining the effect of aloe vera gel on the taste and aroma of jackfruit.

ABSTRACT Passive drying is a drying mechanism that utilizes sunlight in a drying chamber with natural air flow mechanism. The tool used is direct passive solar box dryer. Direct type passive drying is a drying mechanism in a drying chamber with an air flow mechanism where direct sunlight enters the drying chamber. This study was intended to determine the pattern of decreasing water content and moisture ratio of yum (Dioscorea alata L.) and the appropriate drying model. Passive drying of yum tuber slices is done in two stages. The first drying data is used to determine the most suitable drying model (biggest R2). While the second drying data is used to validate the accuracy of the model predictions obtained. The drying process is carried out by placing the sample at the top, middle, and bottom of the drying chamber. The samples used are two types of yum namely white yum and purple yum with a size of 3x3x1 cm. The models evaluated for compatibility are Newton, Henderson & Pabis, and Page. The results of the analysis show that the Page model with the equation MR = exp (-ktn) is the most suitable model to describe the pattern of decreasing water content and moisture ratio of yum. The values of the Page equation constants are obtained as follows: k = 0.187249, n = 1.17272 and R2 = 0.999403. Keywords: Yum, Drying, Drying Model, Water Content

One of the efforts to accelerate the achievement of corn self-sufficiency is the efficiency of farming through the use of agricultural machinery. The use of agricultural machinery at the farm level especially in planting and fertilizingis still scarcely done, while the availability of agricultural labor is decreasing recently. Innovations will be adopted by farmers based on its performance in the field which should be applicable and efficient. The study aims to determine the performance of seed planters as planting and fertilizing tool on dry land in Sigi Regency. The research method uses agro technical studies that measure theoretical work capacity (Kt), actual work capacity (Ka), as well as the efficiency of seed planter and tugal performance. The results shows that seed planter’s performance is higher than tugal. The seed planter has an average theoretical field capacity 1.92 ha/hour with an advanced speed of 6.42 km/hour and has an actual field capacity 0.625 ha/hour, whiletugal toolhas theoretical capacity 0.50 ha/hour with an average actual field capacity 0.167 ha/hour. However, the accuracy of the volume of seed and fertilizer fallfrom the seed planter have to be improved.
