Abstract

The use of chemical fertilizers that are not equalized with organic fertilizers can damage the soil fertility and it is not environmentally friendly, because the microorganisms which have a role in decompose process will not develop. On the other hand, the high prices of organic fertilizers make farmers reluctant to use organic fertilizers. To solve this problem, farmers could be used microorganism with culturing process. The purpose of this research is to determine the comparison of EM4 with culturing process and EM4 in commercial liquid organic fertilizer that applied in mustard plants. This study used a completely randomized design with three treatments, where the treatment was explained as P0 (control), P1 (EM4 commercial), P2( EM4 by culturing process ). The data were taken in the form of plant height, leaf width, and number of leaves of mustard plants. The conclusion of this study was the application of EM4 with culturing process can accelerate the growth of new leaves, the length and width compared with commercial EM4 and control plants.

Abstract

Red cooking oil is one of the oleofood products derived from CPO whose carotene content is maintained. Carotene is an important compound for the body because it can act as provitamin A. In addition, carotene is also a natural antioxidant for the body. The process of making RPO goes through several stages, one of which is the deodorization process. The deodorization process in making palm cooking oil is different from the deodorization in making RPO. Deodorization in making RPO is no longer intended to reduce ALB but only to improve the aroma of the oil. While deodorization at high temperatures can actually reduce the carotene content in RPO. This study was conducted by varying the deodorization temperature so that the optimal temperature was obtained to eliminate the odor in the oil but still had high carotene and the aroma was still preferred. This study was conducted in the Palm Oil Processing Engineering Laboratory by varying the deodorization temperature, namely 900C, 1200C, and 1500C with a pressure of 36 mmHg.

Abstract

Biodiesel is an alternative diesel fuel made from renewable materials such as vegetable and animal sources. Used cooking oil is waste cooking oil that is often found in households, very easy to obtain and always available all the time. Used cooking oil can be used as raw material for making biodiesel because it contains triglycerides through a transesterification process with the addition of a base catalyst, one of which is the ash of empty palm fruit bunches. This research aims to determine the effect of adding ash from empty palm fruit bunches on making biodiesel from used cooking oil. The method used in this research is transesterification with the addition of a catalyst of empty palm fruit bunch ash varied at concentrations of 1%, 2%, 3%, 4%, 5% with a mole ratio of 1: 6 (oil: methanol). The tests on the biodiesel produced consist of acid number, viscosity and density.
