Abstract

Project management is a process of activities to manage organizational resources owned by the company to achieve certain goals. The Terbangi Besar-Kayu Agung Lampung toll road construction project is a project that must be completed in a short time. This study has a purpose to evaluate the performance of the construction project of the Terbangi Besar-Kayu Agung Lampung toll road using the PERT and CPM methods with a toll road length of 189.2 km (117.6 miles). Based on the results obtained by using these two methods, the project completion time which was originally 238 days can be completed in just 119. There are several alternative proposals. The alternative proposal by adding work shifts that have crashed 32 times has an optimal cost of IDR 39,154,229,627.03 and an optimal time of 119 days. While the alternative of increasing the capacity of the equipment produces an optimal time of 189 days and an optimal cost of IDR 39,205,747,076.44 with the crashing process reaching 12 times of crashing. The Toll Road Development Project Planning is scheduled to have a normal time to work for 238 days at a total cost of IDR 39,349,097,164.38.

Abstract

All human activities are very easy due to the rapid development of information technology. Website is a product of information technology. Currently, the use of websites has mushroomed everywhere as a promotional medium to other uses. Cafe XYZ is one of the sellers of various processed coffee drinks in Surabaya. Before the research was conducted, the cafe cashier's transaction process was still carried out in a conventional way only by relying on a notebook which was very inefficient. Not only that, it is also very difficult in the process of managing the data recap, the possibility of the data being lost is very high. The researcher offers a website-based information system design with the Laravel framework supported by a development method, namely SDLC (System Development Life Cycle) which is connected online on the internet so that it can be accessed by anyone and anywhere. With the design of this cashier website, it is hoped that it can help and simplify the transaction process, process product data collection, and also recap transaction data to be more effective and efficient and can save time and costs.

Abstract

In the process of treating raw water into clean water, the pathogenic bacteria must be eliminated. The process of eliminating pathogenic bacteria which then cause an unpleasant odor can be carried out by disinfection. The thing that needs to be considered in the context of disinfection is how to prevent the transfer of germs to the human body through clean water by breaking the chain between the two by means of disinfection. This research begins with a laboratory test of the total coliform content in water treated by Biofilter without disinfection. The laboratory test results showed that the content of Fecal Coli was 1880/100 ml and the bacteria in the Coli group were 2060/100 ml. This parameter must be reduced to the limit according to the Environmental Quality Standard (BML) using a disinfection treatment. From the observations made on the coagulation process from raw water it can be informed that in the range of observed variables, with an increase in the dose of Calcium Hypochlorite (Ca (OCl) 2) from 1 mg / lt to 3 mg / l in the disinfection process, the number of E. coli bacteria which is being lowered more and more. At a dose of Calcium Hypochlorite Ca (OCl) 2 2.5 mg in 1 liter of raw water for the Kebon Agung Canal Drainage Channel with a stirring time of 30 minutes was able to reduce the number of E. Coli bacteria by 99, 40%.
