Abstract

Improving the quality of liquid smoke is carried out by purification (adsorption and distillation) usingvariations in column length and type of adsorbent. This study aims to determine the effect of the type ofadsorbent (activated charcoal, silica gel, and zeolite) and the length of the column (5 cm, column 10 cm,and column 15 cm) on the duration required to purify liquid smoke. Parameters analyzed consisted of aroma, color, long purification time, and compound content. The liquid smoke compound content test by the GC-MS test. The results showed that the column with a length of 5 cm and the type of silica gel adsorbent was the fastest purification time at 138 minutes. The length column of 15 cm and the type of activated charcoal adsorbent were the longest purification time at 207 minutes. The results of the GC-MS test show that activated charcoal adsorbent is the best liquid smoke with specifications of a whitish yellow color and clear, not strong aroma, and a phenolic compound content of 12.88% in accordance with the quality standard of liquid smoke according to FAO 2001 which is allowed for use as a food preservative.

Abstract

Microgreen has the potential to be developed in urban farming systems because of the ease of obtaining planting media and tools to use and can be cultivated on a limited land space. Microgreen radish (Raphanus sativus) is an antioxidant that is good for health and acts as a source of polyphenols. This study aims to determine the growth characteristics of microgreen radish on the effect of variations in planting media and LED grow light and determine the treatment that produces the best growth. The experimental design used in this study was a completely randomized design (CRD) with two factors: the planting media and irradiation with a factorial pattern of 3 x 3 with three replications, so there were 27 treatments. The results showed no significant effect (P>0.05) between the growing media and grow light on several microgreen growth parameters. However, using grow light and sand media visually showed the best results in several growth parameters. The image acquisition on the whole microgreen planting tray is needed instead of randomly picking a single microgreen for analysis to get more accurate data in determining the effect of planting media and grow light on microgreen growth parameters.

Abstract

A Erodibility of the soil is the sensitivity of the soil to erosion, the higher erodibility value of the soil the easier the soil erodes. One way to reduce the rate of erosion is by covering the soil with mulch. The purpose of this study were (1) to determi ne the level of soil erodibility in various types of plastic mulch and straw planted with tomato plants, and (2) to determine the type of mulch that gives the lowest level of soil erodibility planted with tomato plants. The design in this study used a Completely Randomized Design with treatment consisting of tomato plants planted without mulch, tomato plants planted using black plastic mulch, tomato plants planted using silver plastic mulch, tomato plants planted using transparent and tomato plants planted using straw. The results showed that treatment without mulch and treatment with straw had a higher erodibility value than the beginning of the cultivation. While treatment using black plastic and using silver plastic had a lower erodibility value than the initial cultivation. In treatment with transparent mulch there was no change in the value of erodibility. Each treatment had different values but had the same level of category, which was very high. The type of mulch who had the lowest value was the treatment silver plastic mulch with an erodibilitas value of 0,58 at the beginning of cultivation and 0,55 at threemonths of planting age

Abstract

This study aimed to determine the marketing distribution channel and analyze the absorption of paprika from the farmer in Baturiti district to the last costumers and calculate the marketing margins obtained in each distribution channel. This research was conducted in July-August 2018. This study used purposive sampling survey. There are five distribution channels of paprika from the farmers in Baturiti regency to the last costumers namely: 1st line (Farmers → Traditional Markets → Consumers), 2nd line (Farmers →Collectors → Suppliers → Consumers), 3rd line (Farmers → Collectors → Suppliers → Costumers), 4th line (Farmers → Collectors → Consumers), 5th line (Farmers → Suppliers → Consumers). The distribution shows that the market level of paprika and farmers’ production is 2655 monthly. The absorption of paprika distributed by farmers to collectors, suppliers, and traditional markets are 25.6 percent, 38.8 percent, and 35.6 percent. Paprika that is distributed by collectors to suppliers andtraditional markets are 19.6 percent and 6 percent. Suppliers obtain 58.4 percent paprika for farmers and is distributed to hotel or restaurant, supermarket and traditional markets each at 29.8 percent, 21.5 percent, and 7.1 percent. Based on the five channels obtained in this study, line III is the longest distribution channel, and lines III and V produce the highest marketing margins and profit margins. While line I is the shortest distribution channel and has the lowest marketing margins and profits. This is because the marketing costs incurred are small and the selling price at the last consumer level is also the lowest compared to the other five channels

Abstract

Rice is a staple food for the people of Indonesia. Even though Indonesia is an agrarian country, Indonesia currently imports rice. In producing rice from rice there are obstacles. One of the main obstacles is post-harvest handling of rice with high yield loss during post-harvest. The amount of post-harvest loss occursbecause most farmers still use traditional method or the handling is not good and right. The purpose of this study was to determine the relationship between the capacity of the grinding machine and the quality of sosoh rice produced by the mill and to know the quality comparison of various types of grinding machine capacity. The research was carried out in the area of Wanasari Village, Tabanan - Bali to find out the quality of sosoh rice in the region. Head Rice is broken rice grains, both healthy and defective, which have a size greater than or equal to 6/10 part of the average length size of whole rice grains that can pass through the surface of the indented plate basin with a requirement of 4.2 mm hole size. Rice hull is a protective cover from rice grains which is separated from seeds during the grinding process. In the grinding process, there is rice which remains the husk which is caused by the power / rpm of the grinding machine which is too low because the friction force produced by the engine is not sufficient for the overall release of rice hull

Abstract

The purpose of this study was to maintain minimum moisture content for switchgrass bales that were inoculated with Pleurotus ostreatus, a white-rot fungus, in order to start the breakdown of lignin for conversion to ethanol. The moisture content was to be maintained above 50%, which would be monitored using load cells to determine the weight. Three bales were used, and thermocouple wires and hose system were placed at four points inside each bale. In addition, the ambient temperature and relative humidity inside the building were monitored. Bales were inoculated with 1%, 2%, and 3% grain spawn by mass. The inoculation was carried out by taking the bale apart in four places and sprinkling or spreading the fungal spawn over the bale. In order to continuously record the voltage readings from the strain gauges, NI USB-6225 data logger and National Instruments’ LabVIEW program was used to record and control the system. The develop automatic weighing and watering system had been able to maintain the bale moisture within the acceptable range and the fungus were observed growing. Some issues related to voltage readings and uniformity of water distribution must be addressed for future work
