Abstract

Diesel fuel is used for diesel-engined vehicles containing sulfur, where the quality of diesel oil is expressed by the cetane number, as it is known that the cetane number for diesel fuel is 48. Water content is a parameter that affects the quality of diesel and biodiesel fuel which often increases during the stockpiling process. If the water content value is too high, it can damage the engine and accelerate corrosion. Hoarding for diesel and biodiesel products in this test was carried out with 2 variations, namely temperature variations (outside temperature and inside temperature) and also time variations. The length of the stockpiling process used in this study was 6 hours, where the results obtained from the water content test were also different. From the water content research for biodiesel products, the results were 0.1595% vol, 0.1621% vol for inside temperature, 0.1839% vol, and 0.1845% vol for outside temperature, while for solar products the results were 0.0344% vol, 0.0339% vol at inside temperature and 0.0502% vol and 0.0495 vol % for the outside temperature. It can be concluded that the higher the temperature in the process of storing diesel and biodiesel, the greater the value of the water content

Abstract

Biodegradable Foam is used as an alternative to environmentally friendly food packaging or containers. Starch is the main ingredient in making biodegradable foam because it is cheap, easy to find, low density, and has high biodegradability. However, biodegradable foam from starch has a high water absorption ability, therefore the addition of beeswax is expected as a coating agent to reduce water absorption. This study aims to see the results of the addition of beeswax concentration and the length of time of immersion of the coating to the characteristics of biodegradable foam. This study used starch from cassava skin. The concentration of beeswax used was 5%, and 6% w/t by weight, while the coating time was varied from 1.5; 2, 2,5 ; 3 to 3.5 minutes. The application of beeswax on biodegradable foam produced the best results at a beeswax concentration of 6% with a time of 3 minutes, with a water absorption test result of 3.33%, a biodegradability test of 57.142% and a tensile strength test of 9.14 MPa.

Abstract

Synthesis of resin composites with Gd2O3 filler for neutron radiation shielding applications has been carried out. The material used as a neutron shield is a resin which is added 10%, 20%, and 30% Gd2O3. Resin and Gd2O3 were mixed using a mixer for 1 hour and then a catalyst was added as a resin hardener. The mixture is then put into a mold with an inner diameter of 24.5 mm, an outer diameter of 30 mm, and a height of 25 mm. The prints were dried for 3 hours. The results of characterization with SEM at 1000x magnification show that the sample surface is quite compact and dense and does not show pores. The results of the EDS test showed that in the resin sample with the addition of higher Gd2O3, there was an increase in the percentage of Gd in the sample. The results of the compressive test using the Universal Tensile Machine showed that the compressive strength on pure resin without Gd2O3 was 5167 N, on resin with the addition of 10% Gd2O3 was 5088 N and on resin with the addition of 20% Gd2O3 was 1088 N while on resin with the addition of 30% Gd2O3 of 612 N. It can be seen that with the addition of Gd2O3 to the resin there is a decrease in its ability to withstand pressure.

Abstract

The use of chemical pesticides to control grasshopper attacks harms the environment and people. Therefore, botanical pesticide as an alternative to a safer environment is needed. This study aims to determine the effectiveness of papaya leaves (Carica papaya) and lemongrass (Cymbopogon citratus) combination extracts against Javanese grasshopper based on maceration time and concentration variations, and to determine its compounds. The maceration time was 3, 5, and 7 days, and 30, 50, and 70% concentrations were used. The study showed that a 7 days maceration with 70% extract concentrations is the most effective to kill the Javanese grasshopper with an average mortality rate of 100%. Botanical pesticides are known to contain tannins, flavonoids, terpenoids, steroids, and citronellal. The presence of these compounds in the botanical pesticides causes Javanese grasshoppers which eat plants that have been sprayed to experience death due to poisoning and continuous loss of fluid.
