The Effect of Dryer Air Temperature on The Moisture Content of Cassava Flour in The Pneumatic Drying Process

Drying method that is applied in flour manufacturing industry, one of which is pneumatic drying. Variable types of both the properties of the dried material and the conditions of the drying process greatly affect the quality of the results of drying. Water content is an important variable in determining the quality of flour. The purpose of this study was to find the effect of drying air temperature on the moisture content of cassava flour under the conditions of the pneumatic drying process. Drying of cassava flour at desiccant air temperatures of 145oC and 160oC with 2 drying cycles produced a moisture content of 11.3 and 8.7% wb and had fulfilled SNI for flour water content, which was a maximum of 12% wb. The higher the temperature of the drying air, the lower the moisture content.

Simulation Planting Pattern (Palawija) Based on Potential Water Availability in Kweel Village, Elikobel Distric, Merauke

Agriculture is one of the sectors that play a role in deciding the rural poverty chain. Agriculture is a productive sector for rural communities in increasing household incomes through cultivation of crops and livestock. The purpose of this study is to plan, establish or simulate appropriate planting pattern based on the potential availability of water resources and land, so that the production or productivity of plants and land can be obtained optimally and can improve the rural economy. The method used in this research is descriptive analytic method. Based on the results obtained that the potential of available water resources in Kampung Kweel is able to be used as an irrigation water source in both monoculture and polyculture (tumpangsari).

Conservation of Soil Moisture Using Mulch of Green Bean Plants (Vigna Radiata)

The aim to this study was to determine the effect of plastic silver mulch and rice straw mulch on soil moisture conservation of green bean so that the plant can grow in dry season with enough water. The method used in this study was a randomized block design with three treatments: no mulch (T0), plastic silver mulch (T1) and rice straw mulch (T2). The parameters observed were physical soil of initial and final research, soil moisture measurements every 3 days, as well as growth and crop production parameters including plant height, number of seeds in pods, 100 seeds weight, sample plant production and total production. The results showed that the physical of soil analyzed were clay textured soil, preliminary porosity 60.77 and at the end of the study increased to 77.50%, organic matter 1.52%, initial bulk density 1.04 g/cm3 at the end of the study decreased to 0.60 g/cm3, soil permeability of 7.77 cm / hour and available water is 13.95%. The use of rice straw mulch from the beginning to the end of the study showed the best water content while the use of plastic silver mulch and no mulch showed water content not much different. The use of palstic silver mulch gives the highest yield of the best crops on 14 HST measurements where the plastic silver mulch differs markedly by the rice straw mulch and no mulch. The yield of green beans produced in the treatment of plastic silver mulch using the best results with a total production of 2.00 tons/ha, this result is significantly different from no mulch but not significantly different of rice straw mulch. Rice straw mulch is better used for soil conservation because it can improve soil aeration, retain water, prevent soil erosion, and increase organic matter on the soil.

Aplications of Liquid Organic Fertilizer From Agricultural Waste in Wati Plants (Piper methysticum Forst).

Custom reflects the personality and soul of a society or nation, is hereditary and contains belief values ​​in it. The Wati plant (Piper methysticum Forst) is one of the parts or tools used in a Marind tribal in Merauke Regency. As part of custom, it is necessary to develop so that the custom can be maintained. Therefore, most to find simple propagation and cultivation techniques of Wati plants and later can be applied to the community. This study aim to analyze the utilization of agricultural waste into liquid fertilizer which is applied to wati plants. The metode of study with randomized block design (RBD) with five treatments, is P0 (2 l of water) as a control, P1 (10 mL), P2 (20 mL), P3 (30 mL), and P4 (40 mL). Each treatment was repeated as many as five times, so that 25 experimental units. The parameters observed were the content of N, K, and P2O5, from agricultural waste, stem diameter, number of leaves and stem length. The results showed that the N and P2O5 contents were low, whereas K had met the minimum technical requirements for POC. The results of the POC application showed that the best growth of wati plant seeds for plant height and number of leaves with a dose of 40 mL/L water.

Design to Build A Shallots Drying House with Fumigation in District Tanah Miring

The purpose of this study was to make a simple shallots drying house design with fumigation so that dried shallots were obtained in accordance with the Standar Nasional Indonesia (SNI). The method used in this study is the temperature measurement in the smoke house. The benchmark in testing the smoking house is the temperature used in the room at the smoke house with the construction of a small scale permanent building. The temperature that shallots have to accept is 35-40oC. Temperature data obtained from measurements at 3 observation points in the smoke house for heat transfer analysis. The test results on the design of the smoke house with a shelf design located 2 meters from the ground floor showed that convection heat transfer in the fumigation chamber was stable so as to produce dry shallots with a weight loss of 30%.
