Abstract

The poultry industry in Indonesia is growing rapidly, but still relies heavily on the supply of seeds and feed raw materials from abroad. The abundant meat production leaves innards or chicken carcasses in large quantities.  The use of chicken innards into animal feed is one of the fulfillments of the supply of animal feed availability because it contains enough protein.  Because the period of decomposition of meat occurs quickly, so to overcome this, it is necessary to dry the dried innards in order to stay durable.  This study aims to determine the characteristic value and water content of the equilibrium drying of chicken innards thin-layer as well as observe the color changes of chicken innards.  The study was conducted by an experimental method with two treatments, namely drying temperature and innards type.  The analyses carried out are water content, equilibrium water content (Me), drying constant (k), protein, and color. From the results of the study, it was found that the type of innards (gizzard, liver, and intestine) affects the drying time, final water content, protein, and color but does not affect the equilibrium water content (Me), and the drying constant.  While the drying temperature used affects all observed parameters.  High temperatures (90°C) produce brighter colors because the drying process is shorter. Keywords: Chicken innards, Color, Layer Drying, Thin Protein.

Abstract

This research is about the effect of temperature and thickness level of carrot slices on the quality of carrot flour. Processing and consumption of carrots is still limited to fresh carrots and carrot juice. The advance of technology makes people demand alternatives to fresh materials that have a short shelf life and are less practical in processing them into a product. Carrot shelf life is short resulting in many carrots wasted. Therefore, an alternative is needed to process carrots into flour. The purpose of this study was to study the effect of temperature and thickness level of slices on the quality of carrot flour on water content, color, vitamin C content, and flour density. This research uses factorial completely randomized design (RAL) consisting of 2 treatments and 3 replications. First factor is temperatures of 50 ° C (T1), 70 ° C (T2), and 90 ° C (T3). The second factor is the thickness of the slices of 2 mm (A1), 4 mm (A2), and 6 mm (A3). The parameters observed were water content, color, vitamin C content, and density. The results obtained in this study were the water content obtained ranged from 13.15% - 18.74%. The resulting color resembles fresh carrots that is orange with a color value of 95.087. The content of vitamin C in carrot flour ranges from 0.4425 mg/g - 0.5508 mg/g. The density of carrot flour produced is close to each other in the range of 0.5133 g/cm3 - 0.5142 g/cm3. The difference in temperature and thickness affects the level of concentration and does not affect the content of vitamin C and flour density. The difference in thickness does not affect the color. Keyword: Carrot, Drying, Temperature, Thickness.

Abstract

Preparation of cassava seedlings (cuttings) is usually done manually by farmers using slash or hand saws which are considered less effective today. With these problems, TEP-1 Type Cassava Seed Cutting Tool was made as a solution in the effort to meet the needs of cassava seedlings whose performance needs to be tested on several types and varieties of cassava plants. In this study a completely factorial completely randomized design (RALF) method was used using two treatment factors. The first treatment factor is the cutting machine RPM tested at three levels including the RPM 3500, RPM 4000, and RPM 4500. The second treatment factor is the cassava plant varieties tested at three levels, namely by using Kasetsart varieties, Thailand varieties, and Garuda varieties. The test results were analyzed by analysis of variance using the SAS program. The working capacity of Petokong tools in the Kasetsart variety is 9900 seedlings / hour at RPM 3500, 10620 seeds / hour at 4000 RPM, and 11340 seedlings / hour at RPM 4500. While in Thailand varieties, the working capacity of Petokong tools is 5500 seedlings / hour at RPM 3500 , 8250 seedlings / hour at 4000 RPM, and 8700 seedlings / hour at 45,000 RPM. The working capacity of the Butters in the Garuda variety is 5220 seeds / hour at 3500 RPM, 6300 seedlings / hour at 4000 RPM, and 7020 seeds / hour at 4500 RPM. Based on analysis of variance, the interaction between engine RPM factors and cassava varieties did not significantly affect work capacity, fuel consumption, and the level of uniformity of the performance results of the Supporting Equipment. Keywords: Cassava, Cassava Seedlings, Petokong, Work Capacity.

Abstract

This study aims to determine the effect of pressing duration and particle size on the pellet characteristics of sawdust. The study was conducted in a factorial completely randomized design using two factors. The first factor is the duration of the suppression which consists of four levels, namely 60, 120, 180, and 240 seconds. The second factor is particle size which consists of 40 mesh (fine), 30 mesh (medium), 20 mesh (coarse), and mixed. Sawdust is taken from a furniture industry in Bandar Lampung, then dried in the sun to a moisture content of about 12%, then sieved. Pellet molding was carried out with a mass of about 3 grams of material using a hydraulic press with a mold diameter of 12 mm. Sawdust is fed into the mould, then pressed by a hydraulic system at a pressure of 2 tons (172 Mpa). Parameters observed included density, moisture content, water absorption, pellet strength, pellet color, ash content and durability index. Each measurement was carried out with three replications. The results showed that the pressing duration and particle size affected the pellet characteristics. Biomass pellet made from sawdust had characteristics such as density of 0.813-0.856 g/cm3, moisture content of 8.19-12.15 %, maximum water absorption of 7.06-9.32 %, drop resistance of 99.41-99.66 %, and ash content of 1.087-2.082 %. Keywords: Density, Durability Index, Duration of Compression, Particle Size, Moisture Content.

Abstract

Tomatoes are agricultural commodities that are very susceptible to post-harvest damage. The main problem experienced by farmers is to maintain the shelf life of tomatoes which are not durable and are easily damaged by physical and chemical damage. The purpose of this study was to determine the effect of the depth of the storage pit from the surface of the sand on the shelf life of tomatoes during storage. This study uses a Single Factor Completely Randomized Design (CRD) which has a different depth factor (20 cm, 30 cm, and 40 cm). The observations made were three observations, the first observation was the characteristics of the sand, the second observation was the measurement of temperature in the storage environment, and the third observation was the observation of the fruit characteristics consisting of changes in weight loss, hardness, water content, total dissolved solids and color. The experiment was repeated three times. The results showed that the depth level had a significant effect on fruit color during storage, but the depth level had no significant effect on weight loss, hardness, water content, and total dissolved solids. The shelf life has a significant effect on hardness, moisture content, and total dissolved solids. The shelf life of tomatoes at a depth of 20 cm, 30 cm, and 40 cm is up to 18 days while the shelf life at room temperature which is no longer suitable for sale, starting on the 12th day because the tomatoes have changed color to dark red and the hardness of the fruit has decreased to become soft or criticized with a hardness value of 02,1 kg.mm/s. Keywords: Depth Level, Shelf Life, Tomato.
