Abstract

The impact of drought can affect various aspects of life. One that is threatened by the effects of drought is agricultural land and rice fields, which are threatened with failure due to reduced water supply. South Lampung Regency is one of the largest rice producing districts in Lampung Province, with rice fields covering an area of 38,688 ha, South Lampung Regency is capable of producing 321,822 tons of rice. While Candipuro District is the largest producing district in South Lampung Regency with a total rice production of 55,192 tons of rice. From the magnitude of the potential Candipuro District has drought constraints in utilizing the potential of paddy fields optimally. One of the efforts that can be done to anticipate drought is by mapping the rice fields in Candipuro district which is prone to drought. One of the technologies that can be used in mapping is application-shaped technology called GIS (Geographic Information System) Application. The purpose of research on the level of drought based on Geographic Information System in Candipuro District is (1) to obtain a map of the distribution of drought-prone rice fields in Candipuro District, (2) to determine the level of drought-prone rice fields in Candipuro District, (3) to analyze the dominant factors that affect the level of drought-prone rice fields in Candipuro District. The method used in this study is the method of overlap (overlay) and scoring (scoring) with GIS analysts. Overlay and scoring methods were performed on 5 drought parameters, namely rice field irrigation, slope slope, soil texture, soil solum and rainfall. The results of research on rice field drought in Candipuro district obtained two levels of drought prone, namely, medium and high. Paddy land with a classification of medium vulnerability level has an area of 4,050.43 or comparable to 61.8% of the total area of paddy land in Candipuro district, while the classification of high vulnerability level has an area of 2,503. 3 ha or comparable to 38.2% of the total area of paddy land in Candipuro District. Keywords: Drought, Paddy Field, Candipuro District, Geographic Information System

Abstract

Indonesia is an agrarian country because it has abundant agricultural products, one of its mainstay is corn. Besides rice, corn is one of the staple foods consumed by Indonesian people, but only the corn’s grain are used in corn. The cornhusk and corn cobs are usually thrown away or just burned because they are not used. One of the way to process corncobs waste is by chopped corncobs to be used as animal feed. Corncobs that have been separated from the grains of corn were chopped using a chopper machine (Chopper). All this time, these machines have been widely used by society. However, it still raises problems related to the chopper machine. This study uses the observed parameters, namely the enumeration work capacity, fuel consumption, the uniformity of the enumeration results, and the yield. Based on the result of the study, the effect of treatment on yield was not significantly different, with an average yield value of 94.89%. The highest chopping results of corn cobs is at high rotational speed of 1245 rpm with an engine working capacity of 332.88 kg/hour. The lowest fuel consumption is at a rotating speed of 890 rpm with a fuel requirement of 0.74 liters/hour. The effect of treatment on the distribution of chopped results was not significantly different, with the average value for fine chopping 67.29% and 32.71% for coarse chopping. Based on the ANOVA test, the effect of treatment on fuel productivity was not significantly different, with an average fuel productivity value of 301.61 kg/liter. Keywords: Chopper, Chopper Machine, Corn, Corncobs, Rotating Speed.

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 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

The aims of this research were to determine the effect of temperature and duration of blanching to the characteristics of breadfruit flour and to test the level of consumer preference of cake made from breadfruit flour. Completely randomized factorial design with two factors: temperature (60°C, 70°C, 80°C) and duration of blanching (4 and 6 minutes) was conducted. The parameters measured are fineness modulus, grain size distribution, bulk density, color index and organoleptic score of cake made from breadfruit flour as a part or overall materials. The results showed that the temperature and blanching time affect the fineness modulus and of breadfruit flour granules. The higher the temperature, the longer the blanching time, and the smoother the fineness modulus, the finer the breadfruit flour granules. While, the lower the temperature and the duration of blanching, the color index of breadfruit flour is getting closer to white. The cakes made from 100% of breadfruit flour still have lower preference score compared with the cakes made from 100%  of wheat flour in terms of taste, aroma, texture and color. Keywords: Blanching, Breadfruit, Flour.
