One of the crops which is mostly planted in the country of Indonesia is a rice plant. One of post-harvest process is the drying process. Growing technology in agriculture and food, created grain drying technology better and more efficient than conventional drying, on of them with a mechanical dryer. Mechanical dryer basically done using heat from combustion and air is blown through heater or di…
Composite materials are materials that are currently being developed and their use has been widespread in various industrial and household sectors. Composite is a material formed by combining several materials into one and has new mechanical properties as well. In general, composites are composed of binding materials (matrices) and reinforcing materials which are also called fillers. This resea…
Climate condition influents on various sectors of human life, such as agriculture. Climate forecasting can be done to help mapping the planting period so that agricultural productivity is optimal. Artificial neural network is a method that can be used to forecast climate in the future. In this research, backpropagation algorithm was used to forecast monthly data on minimum and maximum temperatu…
Ginger (Zingiber officinale Rosc) is a type of herb and medicinal plant that has high economic value and has been widely known by the people of Indonesia. Ginger water content at harvest ranges from 85% - 91% wet base. High levels of water cause ginger to be easily damaged if not immediately processed or dried. The purpose of this study was to determine the analysis of variations in air tempera…

Handling post grain harvest before being ground or stored for a long time is drying or reducing water content. It is intended that rice or grain that still has a high water content is not damaged due to microorganisms and other biological activities. According to the Indonesian National Standard Agency, harvested grain needs to be immediately crushed until it reaches a maximum moisture content …
Drying is one way of post-harvest handling to extend the shelf life, especially of agricultural crops. In general, post-harvest drying is only done naturally by drying using heat from solar energy or commonly called conventional drying. In the research on the grain drying process using a fluidized bed drying method in which the drying device was modified by the addition of heat exchanger pipes.…
This study examines thermoelectrics to cool the flowing coolant inside a water block. There were two identical thermoelectrics with a type of TEC2-25408 and dimension of 40 mm x 40 mm x 3.74 mm. The cold side of the thermoelectric was affixed to the top surface of water block, while the hot side of the thermoelectric was attached to the heat pipe. The mass flow rates of the coolant were varied…
There are two methods used in drying rice grain; traditional drying and artificial drying (mechanical drying). Traditional drying is drying process done by using sun rays as source of energy, while mechanical drying is done using any tools (dryer). The best temperature to dry rice grain is at a temperature of 650C. Besides, the best condition of the drying is also influenced by air flow rate an…
Pembangunan di era modern dalam bidang konstruksi menunjukkan perkembangan yang sangat pesat. Penggunaan beton ringan menjadi salah satu alternatif dengan berat sendiri yang jauh lebih ringan daripada beton normal. Kekuatan beton pada umumnya dipengaruhi oleh beberapa faktor, salah satunya perawatan (curing) beton. Curing beton pada elevated temperaturemampu menghasilkan beton dengan kekuat…
