Abstract

The aims of this research was to determine the heat conductivity of river sand with different diameters as a heat transfer medium in the crackers roasting process. This research is experiment research using two types of sand diameter is big diameter sand and small diameter sand at three (3) temperature variations of 120, 140 and 160OC, and four (4) variations long of roasting is 10, 15, 20 and 25 seconds. During the roasting process do temperature measuremen on the sand and crackers, calculating the value of thermal conductivity of the sand and measurement of moisture content. The results showed that the smaller diameter of the sand cause heat transfer the faster so thermal conductivity value higher. The higher the temperature and the longer roasting process using small sand cause the heat transfer faster so the evaporation of water content in the crackers is greater. The higher the thermal conductivity value of the sand, so heat transfer is getting better.

Abstract

The purpose of this research is to know the conductivity and coefficient of heat transfer in drying process of gabah (unhulled rice) by using cabinet dryer. This research is a type of experimental research done by drying "gabah" with temperature variations 50OC, 60OC and 70OC while the duration of drying 160 minutes, 170 minutes and 180 minutes. then to know the temperature change during the drying process used thermocouple, while to know the change of  "gabah"  water  level  is  done  by  water  content  test  before  and  after  drying  by  using  ov en  method. The results show that the higher the drying temperature, the "gabah" temperature will be close to the temperature of hot air, while the moisture content the higher the temperature and drying in a long time will cause the "gabah" water content decreases. The value of the  "gabah" conductivity and the heat transfer coefficient of the"gabah" is 0.32 W/m.OC and 31.77 W/m2.OC.

Abstract

The processing of fruits by frying are interesting to be developed. One of the potential fruit processed and fruit chips are developed  papaya (Carica papaya L.). This study aimed to determine changes in water content and volume of papaya chips during frying, and test results hedonic papaya chips. The study was conducted by using the experimental method completely randomized design (CRD) with observation every 15 minutes, for 90 minutes during frying using vacuum fryer. Observations moisture content, volume, and the level of preference (hedonic), performed before and after frying. Analysis of the data by analysis of variance (ANOVA) followed by Tukkey test at 5%. The results showed that the decrease in water content and volume reduction papaya chips tend to stop in a frying for 60 minutes. To test hedonic color and flavor, crispy papaya highly preferred is frying for 60 minutes. As for the hedonic test on the texture, chips are the most preferred frying for 90 minutes

Abstract

Estimation of soil erosion 3D (E3D) provides basic information that can help manage agricultural areas sustainably, which has not been sufficiently conducted in Indonesia. Sumani watershed is main rice production area in West Sumatra which has experienced environmental problem such as soil erosion and production problem in recent years. 3D Agro-ecological land use planning based on soil erosion 3D hazard and economic feasibility analyses consist of production cost and prize data for each crop. Using a kriging method in Surfer tool program, have been developed data base from topographic map, Landsat TM image, climatic data and soil psychochemical properties. Using these data, the Universal Soil Loss Equation was used for spatial map of soil erosion 3D and proposed a 3D agro-ecological land use planning for sustainable land management in Sumani watershed. A 3D Agro-ecological land use planning was planned under which the land use type would not cause more than tolerable soil erosion (TER) and would be economically feasible. The study revealed that the annual average soil erosion from Sumani watershed was approximately 76.70 Mg ha-1yr-1 in 2011 where more than 100 Mg ha-1yr-1 was found on the cultivated sloping lands at agricultural field, which constitutes large portion of soil erosion in the watershed. Modification of land use with high CP values to one with lower CP values such as erosion control practices by reforestation, combination of mixed garden+beef+chicken (MBC), terrace (TBC) or contour cropping+beef+chicken (CBC) and sawah+buffalo+chicken (SBC) could reduce soil erosion rate by 83.2%, from 76.70 to 12.9 Mg ha-1 yr-1, with an increase in total profit from agricultural production of about 9.2% in whole Sumani watershed.Key words: CP-values, Erosion 3D, land use, Surfer Tool, USLE [How to Cite: Aflizar, AC Idowu, R Afrizal, Jamaluddin, E Syafri, Muzakir, Husnain and T Masunaga. 2013. 3D Agro-ecological Land Use Planning Using Surfer Tool for Sustainable Land Management in Sumani Watershed, West Sumatra Indonesia.

Abstract

Expansion and puffing are specific characteristics of fried products critical for consumer preferences. To obtain expanded and puffed dried products that fit well with consumer acceptance criteria, it is necessary to pay attention to the process conditions which change the raw material characteristics during frying. The important changes include volume and density ratio of the products during frying. Hypothetically, these changes are due to water vaporization and the decrease dry matter in the products. The objective of this research is to develop a mathematical model of volume and density ratio changes for jack fruit during vacuum frying as a function of water and starch content reductions. Samples were vacuum fried at 70–100OC and pressure of 80-90 kPa for 15–60 min. The parameters observed were volume and density as well as water and starch contents of samples before and after vacuum frying. The results showed that the developed model can be used to predict changes in volume and density ratio of jack fruit during vacuum frying.
