Abstract

Ginger is a horticultural plant that can be used as a spice or medicine. Slicing is the process of reducing the size by using a knife to get the length of the pieces that are smaller and thinner in a transverse, oblique or parallel direction to the material to be cut. The traditional slicing process is still relatively time consuming so it is not practical and cannot meet the needs. This study aims to design and performance test slicing machine type horizontal for red ginger and elephant ginger. The design is carried out on the hopper component and slicing system. The slicing performance test was carried out at rotational speeds of 46.67 rpm, 56 rpm and 65.33 rpm using 2 and 4 slicing blades with three replications. The results of the design show that the hopper using a clamping system can accommodate 13 kg of ginger. The testing results of the slicing system got the largest machine performance efficiency of 87.4% at rotational speed of 56 rpm with 2 blades with a slicing of 262 kg/hour. This slicing is very large compared to traditional slicing (3 kg/hour) and greater than previous studies with a slicing machine that uses a pressing mechanism (128 kg/hour).

Abstract

Analog rice can be used as a diversification and substitution of rice, in order to overcome the shortage of rice production, breadfruit become the choice in making analog rice because of its very much growth in Indonesia. The purpose of this study was to determine the effect of tapioca flour concentration in making analog rice which is the main raw material for breadfruit flour. The process of making analog rice includes weighing the ingredients, mixing the ingredients, granulating the ingredients, and giving water. This research method is mixing breadfruit flour with tapioca flour with five levels, namely 0%, 5%, 10%, 15%, and 20% tapioca flour with the testing stage is analog rice steaming, rice drying, measurement of test parameters, data and test results parameters, then the parameters observed were (water absorption, grain diameter, water absorption, bulk density and proximate). The more tapioca flour additions, the analog rice water content increased ie the first treatment was 7.11% while the fifth treatment was 7.91%. The more tapioca flour is added, the less weight percentage with grain size <2 mm while the percentage weight with 4.7 mm grain size is getting higher. Then the addition of tapioca flour to water absorption decreased the first treatment by 102.69% and the fifth treatment was 88.01%.

Abstract

The performance of the irrigation network can be seen from several aspects such as the condition of the door and the suitability of the discharge coming out of the measuring instrument or door opening that is operated. This is used as information and input in the management of irrigation networks so that the distribution of water can be precise and even as well as a benchmark in evaluating water distribution. The performance of the tertiary irrigation network is measured based on six parameters. This parameter will determine whether or not there is an error in the management of the irrigation network. Good irrigation network performance will produce water discharge in accordance with irrigation water needs in each tertiary plot. The performance of the tertiary irrigation network on the Crump De Gruyter type has a very good performance. The level of efficiency of water use in the downstream area is higher than in the middle and upstream areas. Water distribution was 1.07 l/sec/ha during treatment, 0.82 l/sec/ha during plant growth and 0.4 l/sec/ha plant ripening.

Abstract

Biomass is organic material produced from the process of photosynthesis. Biomass can be produced directly as a product or waste from processing agricultural or plantation products. One of the most abundant biomass is the waste generated from oil palm processing, including oil palm empty fruit bunches (OPEFB). Basically, OPEFB waste is only used as natural mulch or only disposed of in oil palm plantations. There are very few processing methods that convert into uniform shape and size biomass pellets, biomass pellets require an additional process called torrefaction, this is done to make bioenergy utilization more optimal. The quality of biomass pellets can be improved through torrefaction, which is a heat treatment process at a temperature range of 200°C–300°C under limited oxygen conditions. This study aims to examine the effect of torrefaction on the characteristics of OPEFB pellets. Pellet torrefaction uses a rotary reactor tube, a device that performs torrefaction with a tube that rotates 360º on a support shaft with the help of a transformer. Torrefaction temperatures applied were 220°C, 240°C, and 260°C with 15, 25, and 35 minutes. Pellet testing includes changes in chemical composition. The results showed that the water content of the pellets decreased from 10.57% to 1.64%. The water absorption test also showed that the torrefaction pellets were more resistant to water, so it would be very beneficial when the pellets were stored in humid conditions. Torrefaction causes a decrease in cellulose content, hemicellulose, and an increase in lignin content. Torrefaction with reactor tubes can improve the quality of EPEFB pellets and increase the added value of the product.
