Abstract

This study conducted to get drying equipment a moringa leaf using air temperature from an air conditioning condenser. The first steps taken were collecting research literature, formulating problems, and design a drying equipment moringa leaf (moringa oleifera) using air temperature from an air conditioning condenser. Drying equipment tool made from plywood, wood, aluminum foil, styrofoam, and pipe channel to drying equipment. It works by utilizing air from the air conditioning condenser which is channeled through a pipe channel to drying equipment. The test was carried with modification intake channel to drying equipment without suction fan and using suction fan. Data collection is carried out every 30 minutes for 7 hours which starting from 10.00 AM to 05.00 PM. A sample of 800 grams of wet moringa leaf was placed on each drying rack. The result study without suction fan in the drying equipment show average temperature air from the condenser of 31.17 °C, average humidity of 68.8%, and a reduction in water content of moringa leaf of 35.5%. Meanwhile, the test using an air suction fan in the drying equipment was average temperature air from the condenser 34.10 °C, average humidity was 62.30% and the reduction in water content of moringa leaf was 40.8%. The drying rate of moringa leaf in the test using an exhaust fan is 0.0138 kg/hour, while the drying rate of moringa leaf in the test without using an exhaust fan is 0.01 kg/hour.

Abstract

Palm shell is a waste from palm oil production which is shaped like a shell with a hard layer character that aims to protect the palm kernels. The addition of palm shells to concrete is an innovation and breakthrough in the more productive use of palm oil waste. In this study, the percentage of addition of palm shells was used, among others, 0%, 7% and 14% by weight of cement with variations in the cement water factor (FAS) of 0.35, 0.45 and 0.50. The test object used was a cube (15 x 15 x 15) cm with a total of 9 test objects for each FAS with a test time of 28 days. The results of the concrete compressive strength test obtained data for FAS 0.35, the average compressive strength for BTCS was 348.15 kg/cm2, BDCSA (7%) was 363.07 kg/cm2 and BDCSB (14%) was 302.90 kg/cm2. FAS 0. 45 the average compressive strength for BTCS was 292.59 kg/cm2, BDCSA (7%) was 303.20 kg/cm2 and BDCSB (14%) was 249.27 kg/cm2. FAS 0.50 average compressive strength for BTCS was 273.09 kg/cm2, BDCSA (7%) was 271.53 kg/cm2 and BDCSB (14%) was 219.47 kg/cm2. The test results show that the average concrete compressive strength is influenced by the cement water factor (FAS) and the percentage of addition of palm shells in the concrete mix.
