Abstract

Heat exchange causes cold water to change temperature where the cooling water temperature to rise because the resulting heat is carried by a fluid which is absorbed by the water. To overcome that we need some cooling to reduce the temperature of the water is by using a cooling tower. The goal is to find out and determine "the effect of adding a cooling tower to decrease the water temperature in the cooling bath steam distillation process of (Cymbopogon citratus) leaves ". Measure the temperature every 30 minutes after the distillate water dripping, and the process of repeated measurements simultaneously on a water bath cooler, condenser, cooling tower (cooling tower) and the distillate water. The process of measuring the temperature using a cooling tower with a water tank initial temperature was 270C with the old process for 3 hours. From this research can be concluded that: 1)At the time of the process without using an intermediary Cooling Tower For media water cooler during the 3 hour difference between 2-30C temperature rise to a maximum temperature ranging between 41-430C. 2) Cooling Tower Process using water as a cooling medium for 3 hours process, the maximum temperature ranges between 31-340C and the difference in temperature rise between 1-20C. 3)Comparison of the temperature of the process without the use of Cooling Tower and Cooling Tower using cooling water as its medium very different temperature difference is 34 : 430C with a temperature difference of 90C without using the Cooling Tower to use the Cooling Tower.

Abstract

Land is an important aspect in the planning of construction. Because the land has the standing of a building. Therefore, it is important to take into account the stability of the soil. One of the ways used to control the stability of the ground so as nor to experience sliding is to build a retaining wall. Planning retaining wall is located on the Weybolar River, West Southeast Maluku District and located on seismic zone 5. On this plan, the data used comes from the Public Works Department of Mining and Energy, West Southeast Maluku District. The planned retaining wall is a kind of gravity. So this building can function properly, then the stability of the building should also be good. Therefore, the author tries to analyze the stability of the retaining wall against the danger of rolling and sliding with normal water level condition without the earthquake, with the earthquake and flood water level condition without the earthquake, and with earthquake. Analyze using the Rankine formula. The result is SFsliding 1,77 > 1,5 and 1,38 > 1,2, SFbolters 2,5 > 1,5 and 1,2 ≥ 1,2 (for normal condition without and with the earthquake) and SFsliding 1,93 > 1,5 and 1,38 > 1,2, SFbolters 2,97 > 1,5 and 1,56 > 1,2 (for flood condition without and with the earthquake), it turns out safely.

Abstract

Retaining wall is one of the structures that serves to maintain the stability of a landfill, so the heap is not moving or landslides. This building is mostly used in irrigation projects, highways, ports and others. In general, the use of retaining walls in the field consists of two types of gravity type and cantilever type. The main difference between the construction of these two types of retaining walls is that of the cantilever type, whereas the type of gravity does not use reinforcement. In terms of use, the cantilever type is more widely used for slopes that have a height of more than 6 meters, while the gravity type is used for altitudes less than 6 meters. The stability of the retaining wall can be expressed by the value of Fs (safety factor). The value of the security factor under consideration is Fs Overtuning which is the security factor to the rolling force, Fs Slading is the safety factor of the shear, Fs bearing capacity is the safety factor to the collapse of carrying capacity. Therefore, the purpose of this study is to know the efficiency of the base width of cantilever type cantilever wall on Abd.Manan Wijaya Road which is located in Kaweden Village, Ngantang District, Malang Regency so that it is stable to the style of bolsters, shear and soil bearing capacity. After the calculation, the result of stability factor to shear 1.61> 1.5 (safe), stability to bolsters 2.0> 1.5 (safe), Stability Against soil bearing capacity 142,795> qa = 123.39 kN / M2. Then it can be concluded that the condition of cantilever cantilever wall stability is safe against danger of bolsters, shear and soil bearing capacity.
