Abstract

Currently, the public's tendency to consume traditional medicines is quite high, based on the existing potential, the medicinal product that can be widely developed is the turmeric plant. Turmeric stored in dry powder form has a lower curcumin content than fresh turmeric, namely containing 3-5% curcumin. Therefore, storing turmeric in powder form with a low water content is one way to maintain the quality of turmeric. This research was carried out with three treatments with three repetitions, including drying with a tool using solar energy, drying with a tool using electrical energy, drying with a tool using solar energy and electrical energy (hybrid), and drying using a winch (as a control). . Observations carried out to determine the physical properties of the turmeric flour produced were in the form of color measurements, bulk density measurements, air absorption measurements, stack angle measurements, and measurements of the degree of fineness of the material. Based on the results of the tests carried out, drying using solar and electric energy (hybrid) takes 8 hours, followed by testing using electric energy which takes 10 hours. The flouring process is carried out by blending dried turmeric for 5 minutes. The temperature and type of treatment carried out during the turmeric drying process did not have a significant effect on the turmeric flour produced. Keywords: drying, hybrid, flour, turmeric.

Abstract

Catfish nurseries are required to be able to see the appropriate needs for catfish larvae, especially in pond water quality. However, in its application, generally adjustments to the needs of water quality are only carried out without any special treatment, so that the survival obtained is still low. The purpose of this research is to make a machine that can control the quality of catfish breeding water, test the performance of the machine and the effect of its use. This study used the method of formulating and evaluating the design and testing the performance of the machine which consisted of several stages, including: formulating and evaluating the design, manufacturing the machine, functional testing, performance testing, and the influence of the machine performance. The results obtained after testing were the performance of the machine affecting the speed of hatching eggs, the growth rate and survival of catfish larvae. The speed of hatching catfish eggs is 4 hours faster using a machine. The growth rate using a machine is 0.061g/head, while without using a machine it is 0.053g/head. The survival of fish larvae using machine was 80.3%, while without using machine was 63.1%. Keywords: Control, Fish Larvae, Growth Survival, Water Quality.

Abstract

Rice straw is a potential agricultural waste biomass for alternative energy sources in the form of pellets. This study aimed to determine the effect of particle size and the addition of rice bran on the characteristics of rice straw pellets. The study was arranged in a completely randomized design with two factors. The first factor was the particle size with four levels, namely P1 (passed a 25 mesh sieve), P2 (between 10 and 25 mesh), P3 (did not pass 10 mesh), and P4 (not sieved). The second factor was the addition of bran which consisted of B0 (0%), B1 (5%), B2 (10%), and B3 (15%). All treatment combinations were carried out with 3 replications. Parameters observed includeded moisture content, ash content, density, and pellet strength. Rice straw has a calorific value of 17.96 MJ/kg so it is potential as a fuel. The results showed that the particle size and the addition of rice bran significantly affected the parameters of moisture content, density, and pellet strength. Moisture content, density, and strength (durability) of pellets increased with decreasing particle size. The addition of rice bran showed inconsistent effects: it increased the strength of the pellets but decreased the density of the pellets. Good rice straw pellets were obtained from fine (passing 25 mesh) to medium (between 10 to 25 mesh) sized particles.
