Abstract

Rivers are one of the important water sources for life on earth. Both humans,animals and plants, all need water to maintain life. Rivers flow from upstream todownstream, moving from high places to low places. Microhydro, or MicrohydroPower Plant (PLTM), is a small-scale power plant that uses water power as itsdriving force, such as irrigation canals, rivers or natural waterfalls, by utilizing theheight of the waterfall (head) and the amount of water discharge. The Cianten Riverhas sufficient water potential throughout the year, reliable discharge, suitablecontours, and has been utilized for PLTM.Data collection techniques in this research include observation and data collectionin the field by observing and recording data on the area of each watershed and thearea of civil building planning. Several models used for hydrological analysis are theTank Model, FJ Mock Model, and Markov Lag 1 Model. Apart from that,researchers also carried out financial evaluations of Microhydro Power Plants(PLTM).The results obtained for the Cianten I PLTM scheme/layout include the dam andintake building, sand trap, waterway, headpond, penstock, powerhouse, and exhaustchannels (tailrace). The generation discharge that can be selected based on the plantfactor value is in the probability range of 35% - 55%. The Cianten I PLTM project isconsidered feasible to be realized if it is in a condition of normal value andincreasing benefits. Under normal conditions, financial analysis and sensitivityanalysis show the Project FIRR results are 9.88%, FIRR on Equity is 36.52%, NPVis IDR. 2,916,937,135, and a BCR of 1.03 with an investment payback period of10.87 years.

Abstract

Semarang is one of the major cities in Indonesia with a population that continues to increase every year. The policy on urban density is not a transportation policy, but this policy has an impact, directly and indirectly, on the city's transportation system. The existence of public transportation facilities serving various urban areas is currently of poor quality, causing various impacts on the community. As a result, many people underutilize these modes and prefer to use private vehicles. The research method that will be used in this research is descriptive quantitative method with a rationalistic approach. The ratio used is a simple statistical method. The data used for the assessment of effectiveness and efficiency is seen from the ratio of Accessibility, Capacity, Punctuality, Ticket Prices, Organizational Characteristics, Environmental Characteristics, Worker Characteristics and Management Practices. The results of this study can be concluded that the pattern of movement of public transport users in the Penggaron-Kalibanteng route area of Semarang City (Trans Semarang Corridor 1) falls into the category of evenly accessible to public transport users easily and effectively by meeting all indicators of the effectiveness and efficiency of public transportation. The effectiveness level of the Penggaron-Kalibanteng route in Semarang City (Trans Semarang Corridor 1) has an average percentage value of 96.23% and is classified as very effective. Easy accessibility, bus capacity is in accordance with the number of passengers, and ticket prices are in accordance with the facilities. SPSS calculation of the effectiveness of public transportation services where what is considered effective is from the assessment characteristics of the elements of Capacity, Ticket prices, Organizational characteristics, Environmental characteristics, Worker characteristics and Management characteristics. Meanwhile, the efficiency level has an average percentage value of 94.50% (Vehicle Utility and Load Factor) which is classified as good and efficient. The results of the SPSS calculation of the efficiency of public transportation services where what is considered efficient consists of assessing accessibility, ticket prices, environmental characteristics and management characteristics.

Abstract

The inconsistency in the quality of paving blocks can result in uneven road surfaces, thereby increasing the risk of traffic accidents. This study aims to determine the compressive strength quality of Holland-type paving blocks from several producers in the city of Semarang, both those made manually and by machine, as well as to understand the reasons behind the dimensional inconsistencies of Holland-type paving blocks from various producers in the city. The research samples were taken from four paving block producers located in Semarang. The test results show that all paving block products from the four different producers meet or exceed the minimum compressive strength values set in SNI 03-0691-1998. This indicates that the products are theoretically capable of withstanding the applied compressive loads. The compressive strength test shows the lowest average value from producer AB at 17.21 MPa, while the highest average value was achieved by producer ADS at 19.3369 MPa. The dimensional inconsistencies of Holland-type paving blocks from several producers in Semarang can be attributed to various factors, including differences in production processes between producers, variations in the raw materials used, and differences in the settings of machines or production equipment.

Abstract

This study aims to analyze road users' perceptions of pedestrian facilities in the Pemuda Corridor (Lawang Sewu – Mall Paragon), Semarang City. Variables such as safety, comfort, accessibility, and infrastructure quality are the focus of this research. Data were collected through questionnaires with a sample of 400 people, field observations, and interviews. Field study results indicate that despite many positive aspects of the current pedestrian pathways in the Pemuda Corridor, there are still deficiencies that need improvement. Certain areas require additional zebra crossings and traffic lights to enhance safety. Furthermore, cleanliness and maintenance of the sidewalks in some spots are still suboptimal. Accessibility for people with disabilities also needs enhancement, as there are still obstacles such as vehicles and vendors occupying the pedestrian paths. The physical condition of the pedestrian pathways is generally good, but some areas require upgrades. These findings imply the need for municipal government intervention to improve the safety, comfort, and accessibility of pedestrian pathways through the addition of safety facilities, stricter enforcement of regulations, and regular maintenance programs. Involving the local community in the planning and management process of pedestrian pathways is also recommended to identify problems more effectively and develop solutions that meet community needs. With these steps, it is expected that pedestrian facilities in the Pemuda Corridor and other areas in Semarang City can be improved to create a safer, more comfortable, and inclusive environment for all pedestrians.
