Abstract

This research uses coconut shell ash and glass powder to replace part of the cement aims to find out the compressive strength value of concrete and also the value of water absorption. The use of coconut shell ash as much as 5%, 7% and 9% and glass powder as much as 10% of the weight of cement. And also use additive Sikafume as much as 5% of the weight of concrete. For Normal Concrete, the compressive strength value is 12.39 MPa and the water absorption value is 1%. For the compressive strength value of concrete variation BAS1 with 5% ATK is equal to 11.44 MPa and 1.35% absorption, BAS2 with 7% ATK of 10.32 MPa 1.38% absorption, BAS3 with 9% ATK of 7.50 MPa and 1.38% absorption, BAS4 with 5% ATK with 5% Sikafume of 10.32 MPa and 1.22% absorption, BAS5 with 7% ATK with 5% Sikafume of 10.32 MPa and 1.24% absorption, BAS6 with 9% ATK with 5% Sikafume of 8.82 MPa and 1.37% absorption. The optimal concrete compressive strength value is in the BAS1 variation od 11.44 MPa and the optimal  water absorption is in the BAS4 variation of 1.22%. from the results of tis study, it can be seen that the more coconut shell ash used, the lower the compressive strength of concrete and the more water absorbed. This is because coconut shell ash in fine form reacts with free lime Ca(OH)2 and water into a solid mass that is insoluble in water, namely CSH and CAH.

Abstract

PT PLN Unit Layanan Pelanggan (ULP) Langsa is one of the implementing sub-units under the Customer Service Implementation Unit (UP3). The increase in the amount of electricity consumption is soaring high and fast, this has made the standard level of community satisfaction higher as a result of the increasing income of a modern society. A service is considered satisfactory if the service can meet the desires, expectations and needs of customers. The purpose of this study was to determine the gap between customer expectations and perceptions about the services of PT PLN ULP Langsa and the order of priority for service quality improvement that must be corrected first. One of the methods used to measure service quality is the Service Quality (Servqual) method. The results of calculating the servqual value obtained a gap value with all statement items, namely -2.23, this indicates that the services provided by PLN are currently still unable to provide optimal service to customers. Based on measurements of the 5 dimensions of Servqual, the results show that the five dimensions of service quality have values below 0 in order of priority for improvement, namely the Reliability dimension with a gap of -1.01, the Responsiveness dimension with a gap of -0.86, the Tangible dimension) with a gap of -0.62, the Assurance dimension with a gap of -0.56, and the Empathy dimension with a gap of -0.55. Based on the results of the SWOT analysis, the main improvement strategy proposed is the SO (Strength - Opportunity) strategy.

Abstract

Data from the Geological Agency, Ministry of Energy and Mineral Resources (ESDM) in 2018, Indonesia has 37 billion tons of coal with proven reserves of 20.11 billion tons and estimated reserves of 17.02 billion tons. The total reserves increased by 12 billion tons compared to the previous year. To increase production and reserve coal, it is necessary to build mine roads to connect other mining areas. One of them is the work of transporting soil material for road embankment work. The constraints that are often encountered are limited resources and high cost of equipment. Therefore it is necessary to optimize the need for heavy equipment using Quantitative Methods Software (QM) for Windows V5. The data used in this study are primary data taken from the interview process and data in the form of related secondary documents, namely the RAB, Scheduling, SPK and other documents. The tools that will be used and optimized are a lot of digging and loading equipment such as Excavator PC400 with a bucket capacity of 2.6 m3, Excavator PC300 with a bucket capacity of 1.8 m3, Excavator with a bucket capacity of 0.8 m3 and a Dump Truck with a body capacity of 22.3 m3 as transportation equipment. The results of the research data analysis show that the most optimal number of tools needed for the road works is 1 PC300 Excavator unit, 1 PC200 unit and 3 Dump Truck (ADT) units for a work volume of 99.626 m3 and the optimal work duration is 814 hours and the labor cost is Rp. 2,781,227,681.

Abstract

Zircon sand has the major component of ZrO2 with impurities SiO2, Fe2O2, and TiO2. Zircon sand can be synthesized using various methods, such as caustic fusion method. This research purposed to determine the effect of the mass composition of NaOH on fusion process of zircon sand and to find the optimal mass ration of NaOH on yield and characteristics of nano zircon produced. This research was conducted using caustic fusion and precipitation process to obtain the mass ration of NaOH in best zircon sand fusion (melting) process. The nano zircon obtained was analyzed its size using SEM and chemical composition using FTIR. The result show that the correlation between NaOH ration and yield following the equation y = 0.42x2-2.532x+3.908 and R2 =0.9696. It showed that the higher NaOH composition will reduce the size of nano zircon. The optimum NaOH ratio is 1 : 3.6 with size od 41.983 nm and yield 1.84% which in white, odorless and powder texture. The FTIR spectrum showed the presence of the -Zr-O2 functional groups at wave numbers 600 – 700 cm-1.

Abstract

Satellite communication technology in aircraft is used for long-distance communication between aircraft and outside parties, This study uses NS-3 as software to simulate satellite communication process and analyze QoS based on DVB-RCS and DVB-S2 technology looking at  throughput, delay, PDR parameter values. This simulation aims to obtain QoS value of data sent from the user terminal to gateway based on variations in antenna gain and to determine the effect of  interference level caused by noise on user's device on quality of data reception. Results of running from UT to GW five variations of antenna gain, namely 28, 29, 30, 33, 35 Dbi, Average throughput is 29.9301 Kbps, delay is 48.9212 s, and PDR is 29.7322%. For the results of running from GW to UT with same five variations of antenna gain and five variations of noise, is 0 db, 24.7 db, 49, 7db, the throughtput results are 203.549 Kbps with delay of 0, 263834 s, and PDR is 99.91%. The conclusion obtained is that simulation using NS-3 simulator tool with an antenna amplifier has increased throughput, delay, and PDR as well as service quality and level of user interference is stable and doesn’t experience a decrease in package delivery.
