Published: December 2020

Abstract
This study aims to determine whether the lights on street lighting can be optimized by changing the lamp housing, LED electronic drivers and even the use of optical lenses to make lighting brighter and save energy. Assisted by a partner making street lighting by providing a few examples of experiments that have been carried out by these partners to be able to do an analysis of the products that have been produced and made by these partners. Its production is CSL14 code which has a tendency to use glass as a function to protect the LED chip, but it turns out the glass actually reduces the intensity of light. CSL19 code is starting to appear there is an update by using optical lenses with anti-dust and waterproof materials, it seems that the intensity of street lighting can be more optimally. CSL19 product is proven better than CSL14. Based on measurements it was found that the use of optics can increase optimization and lighting can be more scattered. The use of glass lampshades actually also proved to have worse consequences than the measurement of light intensity on CSL19. CSL19 products are equipped with LED driver technology that is able to do adjustable dimming so that the light intensity is proportional to the desired power.

Published: December 2020

Abstract
The increasing population in Indonesia affects the increase in private and public vehicles. This increase in vehicles causes various problems, one of which is the need for parking space. The need for parking space raises various other problems, namely, the reduction in green open land and rampant illegal parking on the side of the road which often causes congestion. Then we designed and implemented a model of the rotary parking system using Wi-Fi as transmission media. This model is expected to be developed further in solving the problem of parking space requirements. This system begins to work when a user logs in using a previously registered ID and password. The user then selects a particular deck through the built application on the smartphone. The user-selected deck will spin and stop so that the user’s vehicle can enter into. After the vehicle is parked, the user reconfirms the control device and the security password will automatically be sent to the user’s smartphone. To pick up the vehicle again, the user will enter the given password into the control device.

Published: December 2020

Abstract
Of the various types of construction projects, contractors often encounter repetitive projects. Many methods have been used for scheduling repetitive projects, but most repetitive scheduling methods have the basis that they are composed of many identical production units. Scheduling repetitive projects using unit-based methods has several constraints such as modeling and applying them to construction projects requiring simplification of repetitive activities to have a single duration and in a fixed production sequence. Therefore, a non-unit-based scheduling method is developed. In this analysis, the project data was obtained from a housing project. Based on the data, an analysis was conducted to look for the effect of changes in the factors used in the non- unit-based scheduling method on the final duration of the project. From the analysis it was found that the factors used in the non-unit-based scheduling method such as duration, priority order of activities, number of resource groups, and relationships between activities greatly influenced the final duration of the project.

Abstract
Changes in sea weather, especially the strait facing the open sea, will greatly affect inter-island underwater drinking water pipelines, which can cause damage to pipelines made from Height Density Polyetheline (HDPE). Damage that often occurs is broken or folded, so repairs will be difficult given the position of the damaged pipe is at the bottom of the sea, so that special needs to be repaired. Repairing underwater drinking water pipes is done by lifting pipes from the seabed with floats made of plastic drums. After the pipe is lifted from the seabed to the surface of the sea water the pipe will be connected in accordance with the connection procedure and subsequently drowned again by installing ballast. The length of the pipe raised to the surface of the sea is taken at least 1.5 depth of the sea on the damaged pipe making it easier to repair or reconnect. To lift one side of an underwater drinking water pipe type HDPE PN.10 bar with a diameter of 110 mm that breaks at a depth of 42 m requires a float of 13 units to be installed on a ballast concrete 6 m apart.
