Abstract

Making sweet chicken eggs using a sugar solution takes 5 days. This study aims to study the effect of the concentration of the sugar solution and the immersion temperature level on the sugar content in broiler eggs after soaking. This study was designed using a Factorial Completely Randomized Design (CRD) consisting of 2 factors, namely the concentration of sugar solution (15%, 20%, and 25%) and temperature (40 oC, 50 oC, 60 oC, and 70 oC) respectively. Based on this research, each treatment was soaked for 120 hours and repeated three times. The results of this study indicate that the concentration and temperature of immersion affect the sugar content and organoleptic content of sweet chicken eggs. The higher the concentration given, the higher the total sugar content produced in sweet chicken eggs and the higher the immersion temperature, the faster the diffusion of sugar into the eggs. Keywods: diffusion, sugar concentration, Sweet egg, temperature.

Abstract

Curly red chili (Capsicum annuum L.) is a horticultural plant that is widely used for food needs. Its use in the industry makes chili as a commodity of high economic value. In general, one of the problems in post-harvest handling of chili is its relatively short shelf life. The aim of the research was to study the effect of stalks on the quality of cayenne pepper during storage. The studies that only used two treatments, namely without stems and with stalks, the study was added to the harvest treatment with the addition of stems from 1 cm stems. This study used a completely randomized design (CRD). This storage uses room temperature with a storage period of 12 days. Each factor and treatment was repeated 3 times so that 9 experimental units were obtained. Parameters observed in this study were weight loss, hardness, moisture content, color, and organoleptic tests. The results showed that the effect of cutting chili stalks at harvest had a significant effect on the moisture content of the material, while weight loss and hardness had no effect. The RGB values of the three treatments showed a continuous decrease for the green color index (Green) and for the red index (Red) showed an increase until the 4th day and decreased until the 12th day. The organoleptic test showed that the texture and freshness parameters had a significant effect on the organoleptic test. Keywords: Add 1 cm Stem, Curly Red Chili, With Stem, Without Stem.

Abstract

Mosquito repellent are drugs used to repel or kill mosquitoes. Eco-friendly mosquito repellent or vegetable mosquito repellent can be made from various types of vegetable raw materials that contain mosquito-killer / repellent compounds such as cassava stem powder waste and citronella.  This cassava stem waste is very potential to be used because it is being one of the environmental problems in Indonesia. This research aims to establish the formation of mosquito repellent made from cassava stem powder and citronella, determine the suitability of quality based on the specifications of mosquito coils produced against SII No.1113-84 and organoleptic testing of mosquito coils. This research was conducted using a completely randomized design (CRD) with five treatments and three replications. The experiment consisted of 5 levels of mixed composition, namely 30% cassava stalks: 70% citronella (P1), 40% cassava stalks 60% lemongrass fragrant (P2), 50% cassava stalks: 50% citronella (P3), 60% cassava stalks.  40% citronella (P4), and 70% cassava stalks: 30% lemongrass (P5). The results showed that the mosquito repellent formed had a circle dimension of 81 cm, a diameter of 12 cm, a light brown color, a width of 7 mm, and a thickness of 4 mm. The quality of mosquito repellent based on the specifications is as follows: the moisture content range from 5.36 - 9.41% which fulfill the 80% quality standard, the burning time range from 3 - 4 hours, and the weight per seed range from 9.35 - 9, 77 grams. Judging from the quality based on these specifications, the mosquito repellent that is made does not fulfill the quality based on the specifications and quality requirements of SII. However, the mosquito repellent made is suitable for use as natural mosquito repellent because it is close to SII. Meanwhile, based on the organoleptic test with aroma parameters, the best natural mosquito repellent are treatment 1, formed by a mixture of 30% cassava stalks and 70% citronella.  Panelists gave an average score of 4.7 with the criteria being fragrant to very fragrant. Keywods: Cassava Stem Powder, Citronella Powder, Mosquito Repellent.

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.
