Abstract

This research aims to study the effect of temperature and banana varieties on changes in physical and chemical properties of banana’s sale after drying.  The study was conducted by an experimental method with two treatments namely drying temperature and banana varieties.  The parameters observed were initial water content, equilibrium water content (Me), drying constants (k), vitamin C, and color.  The results showed that the banana varieties (Green Ambon and White Ambon) did not affect the drying time, equilibrium water content (Me), and drying constants but did affect the final water content, vitamin C, and the panelists' preference level towards the sale colors of bananas produced.  While the drying temperature used affects all observed parameters.  Low temperature (± 50 ℃) is the optimal temperature because the temperature produces yellowish-brown banana color (Cinnamon) on both banana varieties with a preference level of 44.45% very like, the final water content of 15.28% bb with a long drying time of 38.67 hours on Green Ambon bananas, while on White Ambon bananas are 55.56% like, the final water content of 16.55% bb and drying time of 38.50 hours. Keywords: Banana Sale, Chemical Properties, Drying, Physical, Thin Layer.

Abstract

The aim of this research were to analyze the  RPM effect on the Petokong Type TEP 1 cutting capacity. The tools used include TEP-1 Type Cassava Stem Cutter, tachometer, stopwatch, 1000 ml measuring cylinder, 3.4 and 6 inch pulleys. The amount of bait used in this study was 2, 3, 4 cassava stalks. Revolutions per Minute (RPM) modification is done by using different pulley diameters. Pulleys with a diameter of 3 inches produce 3500 RPM, a diameter of 4 inches produces 2625 RPM, and a diameter of 6 inches produces 1750 RPM. Parameters observed in this study included working capacity, fuel consumption, and seed size uniformity. The best working capacity is owned by the B2R1 treatment combination of 9,900 seedlings/hour with the feed amount of 3 cassava stalks and 3500 RPM, while the lowest capacity is 6,000 seeds/hour produced in the B1R3 treatment with the feed amount of 2 cassava stems and 1750 RPM. Measuring fuel consumption is necessary using methods that are accurate and of long duration. In this study, the measurement of fuel consumption only lasted for 2 minutes using the method of adding fuel volume. This will cause a high error in the calculation. The use of Petokong produces a uniformity of above 95% which causes low seedling damage due to cutting.Keywords: Cassava Seeds, Cultivation of cassava, Lampung, Cutting machine, Pulley

Abstract

Sugarcane bagasse is the remaining solid waste from sugarcane (Sacharum officinarum) milling which has the potential to be developed as solid fuel in the form of pellets. The purpose of this study was to determine the effect of variations in pressure and particle size on the characteristics of pellets from sugarcane bagasse. The research was carried out with a combination of variations in particle size (fine, medium, and coarse) and pressure (1, 2, and 3 tons). The results showed that sugarcane bagasse has the potential to be developed as a pellet fuel because it has a relatively high calorific value, an average of 16.53 MJ/kg. Sugarcane bagasse pellets meet SNI 8675-2018 standards in terms of moisture content, density, and ash content. The results showed that although the ash content of the pellets was affected by the particle size, in general, the characteristics of the pellets were not significantly affected by the treatment factors (pressure and particle size as well as their interactions). Sugarcane bagasse pellets have a high water absorption capacity, so they require a good storage method. Keywords: Densification, Density, Pressure, Particl Size, Strength

Abstract

Preparation of cassava seeds is usually done manually so it takes a relatively long time. TEP-1 type cassava stem cutter (Petokong) is a solution to meet the needs of cassava seeds in large quantities and quickly. This study aims to determine the performance of TEP-1 type Petokong and to compare it with manual cutting using a machete and saw, as well as to find out the cuttings of the seeds produced. The research was conducted in May 2019, at the Integrated Field Laboratory, Faculty of Agriculture, University of Lampung. The research was conducted by cutting cassava seeds using 3 different cutting tools, namely machetes, saws and TEP-1 type petokong. The research parameters consisted of cutting capacity, seedling size uniformity, seedling damage and growth test. The results showed that the highest cutting capacity of cassava stems was TEP-1 type petokong which produced 9720 seeds/hour while cutting using a saw produced 3600 seeds/hour and the lowest was cutting using a machete, as many as 1800 seeds/hour. The uniformity of cassava seeds cut using a TEP-1 type petokong is 99%, while cutting using a saw is 95%, and using a machete is 40%. The lowest percentage of damage to seedlings resulting from cutting was using TEP-1 type petokong which was 2%, damage to seedlings using saw was 10%, and using machetes was 20%. The results of testing the growth of seedlings up to the roots explained that cutting using a TEP-1 type of petokong had perfect and spreading root growth, cutting with a saw showed uneven root growth and cutting using a machete the root growth only occurred on several sides of the cassava seedlings. Keywords: Capacity, Cassava Stems, Cutting Tools.

Abstract

This research study aims to determine proper composition of biochar, to find out the efficiency of fertilizer used, and to evaluate the effect of interaction between biochar and urea fertilizer used on the cultivation of green mustard.  This study used Complete Randomized Design (CRD) consisting of 2 factors with factorial arrangement.  The first factor was biochar dosage consisting of: control (without biochar), 5 tons/ha, 7.5 tons/ha, and 10 tons/ha.  The second factor was urea dosage consisting of: control (without urea), 75 kg/ha, 125 kg/ha, and 200 kg/ha.  All treatment combinations were replicated 3 times so there were 48 experimental units obtained.  The parameters observed were: soil properties, biochar properties, plant height, leaf width, number of leaves, canopy area, shoot fresh weight, shoot dry weight, root fresh weight, root dry weight, total fresh weight, water consumption, water productivity, and fertilizer productivity.The addition of biochar is proven to increase the productivity of mustard plants. The use of urea fertilizer had no significant effect, presumably because of the low soil organic matter content. The interaction between biochar doses and urea fertilizer doses was not significant and only significant for the fertilizer productivity parameters. Research also revealed that the optimal dose of biochar for mustard greens is 5 tons/ha, giving an average yield of 88.25 g/plant and fertilizer productivity of 210.41%. Keywords: Biochar, Dose, Green Mustard, Oil Palm Empty Fruit Bunch (OPEFB), Urea Fertilizer.

Abstract

Formulation of specialty robusta coffee added with crystalline coconut sugar is carried out to develop archipelago coffee products. The purpose of this study was to examine the conditions for the production of the best Robusta specialty coffee-crystalline coconut sugar based on physicochemical and organoleptic characteristics. The formulation for specialty robusta coffee crystal coconut sugar uses 3 temperature ranges, namely 60-70 ℃, 70-80 ℃ and 80-90 ℃, and a combination of specialty robusta coffee: sugar 10:0, 9:1, 8:2, 7 :3 g. The analysis carried out included moisture content, pH, yield, and organoleptic tests. The results showed that the highest pH in the specialty robusta coffee:sugar formulation was 7:3, because the more coconut sugar was added to the specialty robusta coffee formulation, the higher the pH obtained. And the yield obtained is mostly produced in the temperature range of 60-70℃. Based on the preference test for color and aroma, it was preferred that without the addition of crystalline coconut sugar, while for the flavor the formulation with the most addition of crystalline coconut sugar was preferred. Keywords: Characterization, Crystal Coconut Sugar, Formulation, Specialty Robusta Coffee, Quality.

Abstract

Corn sheller is a tool designed to improve the results of shelled corn. Based on previous research tests, several obstacles and weaknesses were found in the tool, namely the large corn cobs were stuck and the lever rotation felt heavy. To overcome this problem, it is necessary to modify the corn sheller. The method in this study included modification of a semi-mechanical corn sheller and experiments on a semi-mechanical corn sheller. Testing the performance of the corn sheller was carried out by calculating the value of the parameters including the working capacity of the machine (kg/hour), the amount of shelled corn (%), and the amount of corn that was not shelled (%) which was tested on a semi-mechanical corn sheller with 3 Repeat and add different amounts of corn. The semi-mechanical corn sheller was successfully modified and a prototype of a semi-mechanical corn sheller with dimensions of 30 cm x 30 cm x 171cm was made, by reducing the sheller gear cylinder to 34.16 inches before modifying it to 73.3 inches and changing the sheller teeth to 4 before being modified. 8 gear modification. The sheller with 4 teeth with input of 2 cobs is the sheller with the most shelled results, namely 94% and only 6% is not shelled. The sheller with 1 corn cob was the sheller with the lowest yield, namely only 71.48% and the sheller with 3 corn cobs was 77.40%. The highest work capacity in this semi-mechanical corn sheller is found in 4 teeth, which is 45.81 kg / hour Keywords:  Corn, Machine Sheller, Modifications, and Serration.
