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

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

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.
