Abstract

One of the government's efforts to protect the environment in the Indonesian industrial sector is by establishing laws and regulations that become a reference for the public and business actors and/or activities related to the environment. The government, through the Ministry of the Environment, issued regulations in the form of PROPER as an evaluation of industrial performance in environmental management. Based on the PROPER program mentioned above, the East Java Provincial Government is implementing the Environmental Trust Business/Activity Development Program or known as PUSAKA, which aims to provide environmental management guidelines based on environmental permits held by businesses and/activities (non-PROPER) in East Java. The PUSAKA mentoring program is used to prepare business actors and/or activities in East Java to achieve PROPER. Apart from that, it can also improve environmental management performance in business entities and/or activities in East Java Province, especially PT X. The PUSAKA development program has been successful in becoming a trigger for evaluating PT X's environmental management. Because it succeeded in increasing compliance with PPA and PLB3 by 85.7% and 3.75%.

Abstract

The movement of the Sumatran fault is triggered by plate activity in the western subduction zone of Sumatra, namely the Indo-Australian plate which moves down the Eurasian plate, causing pressure to push the Sumatra region towards the north. The purpose of this study is for the results of Ascending and Descending data on the impact of faults that occur on the Semangko Segment Sianok fault from 2020-2023 and to map the Land Displacement of the Semangko Segment Sianok fault from 2020-2023. Based on the results of data processing in this study, it can be concluded that in this study using ascending and descending direction data that experienced land movement (Land Displacement) due to this movement the impact of faults that occurred due to seismic activity along the segment resulted in the impact of natural disasters such as landslides, and earthquakes. This impact was triggered due to land movement because the effects of surface faults and ground shaking did cause most of the damage in several events. The ascending data explains the annual uplift of 15.28 mm marked in dark blue and the red color on the map shows the subsidence of -30.55 mm per year, while the light bitu color dominates in urban areas or areas inhabited by many people. While in the descending data, changes in land movement show an annual uplift of 6.74 mm and the red color shows subsidence of -13.47 mm per year. From the color change of each data shows ascending and descending data experiencing land subsidence uplift and subsidence.

Abstract

Idle time or disturbing time is time wasted while the ship is moored is a classic problem that has not been solved in Indonesia. Tanjung Emas Port is the busiest port in Semarang City, Central Java, which is a stopover center for providers of sea transportation facilities and infrastructure in the context of loading and unloading means the transfer of cargo from and onto ships to be stockpiled into or directly transported to the place of the owner of the goods through the port dock using loading and unloading complementary equipment. This study aims to determine the effect of port services, ship engine tools, and loading and unloading productivity, on Idle Time at Tanjung Emas Port Semarang. The population in this study were ship crews from the deck departement division and the sample used in this study was 119 respondents. And do not use the sampling technique because the number of samples is the same as the population, then the data is analyzed using multiple liniar regression with the help of (software) Statistical Package (SPSS) Version 26. The formulation of the regression in this study is as follows: Y= 0,597 + 0,368X1 + 0,356X2 + 0,213X3 + m. From this equation it is know that the most dominant variable influencing Idle Time is the port Service variable with a regression coeffient of 0.368. The R2 test ( R The ) obtained a result of 0.443 or 44.3%, which means that Idle Time is influenced by the variable port Services, Loading and Unloadng Speed, and Ship Machinery Equipment which is equal to 44,3% and other factors that affect Idle Time Tanjung Emas Port Semarang, namely 100%.

Abstract

Sweet arum mango is one type of mango which when harvested has the highest vitamin C content of 7.53 ± 0.4 mg / 100 g. Processed sweet arum mango fruit products that have the potential to be developed are in the form of fruit juice. This is a consideration for researchers to conduct further research on the addition of eugenol preservatives with different concentrations of preservatives and storage times to produce better mango juice. Eugenol compounds have pharmacological activities as analgesics, anti-inflammatory, antimicrobial, antifungal, antiseptic, stimulant, so these compounds are widely used in the pharmaceutical industry. Based on the experimental results, optimal conditions for the use of eugenol occurred until day 2, where the addition of eugenol with treatment 3 as much as 1 ml amounted to 38.82% better when compared to other variations of eugenol addition. The addition of eugenol preservatives cannot preserve the content of vitamin C in sweet mango juice even the content of vitamin C tends to decrease. Sweet arum mango juice has a shelf life of 12 days and total dissolved solids of more than 20%, so the resulting fruit juice does not meet SNI 7382:2009.

Abstract

Regency roads are local roads which do not include roads connecting the district capital to other districts, but their network is diverse as a link for local activities, namely connector roads between villages, between sub-districts, production center roads and environmental roads in residential areas. This research focuses on roads in Kaur Selatan District and Maje District, Kaur Regency, Bengkulu Province with a total length of 128.50 km with a total of 68 sections. There are several sub-district roads which are a road network that is integrated with national roads. In general, this road section is often used by various types of vehicles, from light to heavy vehicles. Utilization of roads that do not match their class and the influence of the weather climate in areas that are quite extreme result in landslides so that the road body becomes narrow and heavily damaged. As a result of damage to existing roads, community activities are hampered. The purpose of this research is to provide information to the Bengkulu Regency government in preparing priority planning, determining the type of pavement that is appropriate to the location of the road section and determining the calculation of the costs required. The results of research and calculations show that the cost required for road repairs is IDR. 70,788,844,000 for a period of 5 years. The priority scale consists of 17 sections with a cost of Rp. 57,541,204,000.

Abstract

Self Compacting Concrete (SCC) is an innovative concrete that can compact itself (without vibrators) and flow under its own weight to saturate the shape without segregation. The SCC material is not much different from ordinary concrete, namely coarse aggregate, fine aggregate, cement, water, only SCC has additional ingredients such as superplasticizer. This research uses quantitative methods. The aim of this research is to determine the workability, compressive strength, flexural strength of SCC concrete with the addition of 2% fiberglass to each sample with added material in the form of sika visconcrete with variations of 0%, 1%, 1.5%, and 2%, % of the cement weight. Slump flow testing was carried out which was obtained from several variations of SV `0%, 1%, 1.5%, 2%, the slump flow values were obtained for 80 mm fiber concrete and 550 mm, 575 mm, 600 mm SCC concrete with the time taken to reach 500 mm of 4.25 seconds, 3.57 seconds and 2.11 for SCC concrete. The compressive strength value of the cylinder size (15 x 30) in samples BFS0, BFS1, BFS2BFS3 aged 28 days obtained a compressive strength of 30.29 Mpa, 34.44 Mpa, 31.23 Mpa, while the flexural strength test of the beam was 15 x 15 x 60 d samples BFS0, BFS1, BFS2BFS3 obtained results of 3.11 Mpa, 4.35 Mpa, 3.64 Mpa and 3.29 Mpa, excessive use of visconcrete in the concrete mixture can reduce the strength of the samples.

Abstract

Lightning has always been a dangerous threat to the equipment of electric power systems consisting of: power plants, substations, transmission lines and distribution lines. Generally, overhead high-voltage transmission lines are exposed to lightning strikes. Therefore, the degree of protection against lightning is determined based on the degree of insulation of the equipment. To prevent damage to equipment due to lightning strikes, arresters are used. In this study, three arrester models were used as comparisons, namely. IEEE arrester model. The system was simulated using Alternative Transients Program (ATP) software. The results showed that the lightning rod was declared successful in protecting the transmission system, where the three lightning rods had a Margin Protection (MP) of arresters that reached 28%. In the simulation, it is known that the IEEE arrester successfully cut off the lightning current in the transmission system so that the transient overvoltage recorded on the transformer does not exceed the Basic Insulation Level ((BIL) trafo.
