Performance Evaluation of Floating Solar Power Plant in Sidobandung Bojonegoro
Full text linkSidobandung Village is a village that will develop the potential as a tourism village. One of the potentials that has been successfully built is a reservoir. With the construction of the reservoir in this village, tourism activities began to be seen. The number of visitors who came increases the village's income. Yet, Currently it only open on daytime conditions. Therefore, in its development, there is a desire to open services at night. The problem is how to reduce electricity costs. One of the facilities to support this is to build a floating generator (PLTS) which was built in collaboration with one of the expert vocational colleges in the field of floating buildings located in Surabaya. This floating PLTS is a renewable energy source, in accordance with the village's wish to become an educational tourism village. This floating PLTS is expected to be able to supply 30 lamps which each having a power of 50 watts for street lighting around the reservoir. The total lamp load is about 100 watts. The PLTS system that was built consists of 10 solar cell panels, each solar cell panel has a capacity of 330 WP. With a total of 4 batteries with specifications of 12 Volt 200 Ah. This system is being evaluated. The evaluation results show that the battery capacity is only able to supply 15 lamps for 12 hours. So to supply all the required load, 12 batteries are needed
Asphalt Mixing Performance Evaluation at Province Road Junction Sta 1+700 - 2+300
Full text linkAsphalt mixture is a very important component that needs to be taken into account in flexible pavement construction to achieve the durability of a highway construction. In order to achieve the durability of road construction, it is necessary to control the quality of the mixture used to determine the quality of the mixture used in road construction. Evaluation of the mixture is carried out in the laboratory to check asphalt content, aggregate gradation and field density which must meet the required tolerances for the working mixture (JMF). Evaluation of the asphalt mixture can be done by the extraction method. The extraction method used in this study is the centrifugal extraction method. With this extraction method, the composition of a mixture can be known so that it can be compared with the mixture required in the Job Mix Formula (JMF). In conclusion, there is a decrease in the extracted asphalt content with the planned asphalt content, that is, with an average asphalt content value of extraction results of 6. 58% while the planned asphalt content value is 7.10% with the required tolerance of ±0.3%. In addition to the value of asphalt content, the field density also decreased from that which was planned in the work mix. It is known that the density value in the work mixture is 2,250 g/mm3 while the average field density value is 2,095g/mm3 so that the Job Standard Density (JSD) value is 93.108% and this value is below the tolerance limit. Then the aggregate gradation of the semi-gap HRS WC mixture at the Intersection section of the Lito province on average underwent a gradation change, namely a decrease in the percentage of passing on each sieve
An Analysis of Loss Cost due to Road Clock on the Road Construction (Rigid Pavement) Reviewed by the Use of Oil Fuel
Full text linkThis research was conducted against the background of road improvements on the road section in Ambeng-Ambeng Watangrejo village, Duduksampeyan, Gresik Regency along ± 1.5 km which caused traffic jams due to narrowing of road capacity. Vehicle travel time is very influential on the level of fuel consumption, because the longer the travel time experienced by a vehicle, the more fuel consumption will be. The length of congestion will affect the temperature of the vehicle engine which will get hotter which will eventually affect fuel consumption which will be more wasteful and this will result in a considerable material loss value. This study used quantitative research methods and direct surveys. The primary data used in this study included vehicle travel time and vehicle volume. The types of vehicles analyzed are several types of cars fueled by pertalite. Then the data is processed using references from the Indonesian Road Capacity Guidelines (PKJI 2014) and LAPI-ITB. The results showed that the loss of private cars (KR) fueled by the pertalite type was quite large, namely on Monday, the total loss during the 6 hours of research amounted to Rp.13.575.702 with an average hourly loss of Rp.2.262.617. As for Tuesday, the total loss during the 6 hours of research amounted to Rp.15.942.725 with an average hourly loss of Rp.2.657.121. And for Wednesday, the total loss during the 6 hours of research amounted to Rp.12.182.256 with an average hourly loss of Rp.2.030.37
