Abstract

Water treatment faces challenges in determining the right coagulant dosage due to the slow and manual Jar Test method. It cannot respond quickly to changing natural conditions affecting raw water quality. If turbidity increases and the coagulant dosage relies on outdated data, water quality suffers. Conversely, reduced turbidity with the same coagulant dose results in wasteful spending. To tackle this challenge, this research develops an IoT-based system solution for monitoring and controlling the system. Real-time sensors continuously monitor raw water conditions and relay data to a microcontroller. The microcontroller, in turn, adjusts the coagulant pump via a relay. This innovative system offers a solution for water treatment plants to enhance efficiency and adapt to dynamic environmental factors, ultimately improving the quality and cost-effectiveness of water treatment processes.

Abstract

The state of population growth, which is increasing every year and is not balanced by adequate waste processing facilities, has resulted in many illegal waste dumps. The direction for developing a waste system is carried out as an effort to reduce the burden of waste processing and extend the life of the landfill. The aim of this research is to plan TPS 3R as an effort to manage waste and can be used as material for consideration in planning the construction of TPS 3R in the future. The emergent sampling method refers to 19-3964-1994. Meanwhile, planning is being carried out based on the 3R TPS Technical Instructions by the Director General of PUPR in 2020. The average waste generation is 0.285 Kg/org/d with a volume of 0.00136 m3/org/d. The composition of the waste is 53.48% inorganic and 46.52% organic. The 3R TPS to be built will require a floor area of 588.19 m2. The capacity of waste to be treated is 20.4 m3/day. The 3R TPS is planned to use an open windrow composting process with the help of a bamboo aerator to process organic waste. Meanwhile, inorganic waste will be managed by sorting and grouping by type, which will then be transferred to a third party.

Abstract

The rapid failure of long links in EBF structures occurs at the ends of the links due to the influence of the dominant moment. The use of long links is still very relevant due to the large space openings and meeting the AISC 341 requirements is very easy compared to other links. One of the efforts made to overcome this weakness is to increase the stiffness at the ends of the standard long links. The design of the perforated plate aims to reduce the influence of residual stresses due to wider welds and to control the critical variables. The control arm with the confirmation holes is called the modified control arm. The numerical test variables for the modified long link specimens were the plate thickness (ts) and the vertical distance from the flanges to the edge of the hole in the stiffener plate (Th). The research was carried out numerically to determine the criteria for the initiation of ductile fracture based on the performance indicators of the test specimens using the comparison of failure index and PEEQ index values. The results showed that the initiation of fracture in the flanges at the ends of the beam can be delayed by the addition of double-edged stiffener plates, this can be seen from the decrease in MRI and PEEQ index values in the critical zone of the modified long beam test specimen compared to the standard long beam.

Abstract

The morphology of Rice Husk Ash (RHA) geopolymer microstructure particles obtained by using a kiln at a temperature of 700oC produces a grain shape that is different from the RHA material burned by hand. Theshape of the microstructure particles for geopolymer concrete paste determines the strength of the geopolymer range. The research results show that the shape of the granules obtained by firing in a kiln has a crystalline shape Meanwhile, the shape of the particles obtained by manual firing is amorphous. Theresults of compressive strength tests with amorphous particle structures have greater compressive strength than those in crystalline form. This is demonstrated by testing the RHA furnace material and manually using SEM (Scanning Electron Microscopy) and XRD (X-Ray Diffraction) tests, which show that the granules obtained from furnace burning are crystalline and those obtained from manual burning are amorphous. Crystalline particles are more difficult to react with than amorphous particles in geopolymer concrete mixes. The XRD test results show the highest diffraction by the silica element. The chemical content of silica elements in rice husk ash was found to be 94.9%.

Abstract

The redesign of the die design in the blank-pierce process for the RH/LH quarter panel extension reinforcement product was carried out using field observations to obtain actual data. The production process consists of five stages: blanking, piercing, restriking, bending and forming. Meanwhile, in the redesign process, the RH/LH quarter panel extension reinforcement product is evaluated in the blanking and piercing die processes. Cycle time analysis after the tool design has been redesigned shows the potential for increasing efficiency by reducing process time. MPP data is used as a guide for die design with relevant machine specifications, die size and materials. Machine pressure and tonnage calculations were carried out for the current die design and the revised version, showing significant improvements in production efficiency. The die redesign was carried out to increase output per stroke and to use more sophisticated automation processes. The results of this research show that improved die design can increase production efficiency and productivity by reducing the number of strokes required and properly adjusting machine capacity.

Abstract

The SN Multi-Business Cooperative (KSU) is located in Getasan District, Semarang Regency. This cooperative collect cow's milk which is cooled to a certain temperature and sent to milk factories and restaurants and cafes. The problem that often arises is that milk that has been sent to the milk factory can be rejected for various reasons. To carry processed milk, every motorbike rider uses a basket bag made of thick cloth which is mounted on the back of the motorbike. Using this basket bag is less practical because if the driver wants to refuel, the basket bag must be removed first. The design of the portable cool box mounting frame makes it easier for drivers to refuel. The portable cool box's mounting frame is designed to transport milk more effectively, using a cooling stand that can be removed, which is more ergonomic, making it easier to refuel.

Abstract

The intersection of Jl. Yos Sudarso - Jl. Galaxy is a 3-phase intersection with commercial land use, so on several approaches there are side obstacles in the form of parked vehicles that prevent road users from crossing the intersection, causing frequent queues. The aim of this research is to find out how the signalised junction is performing and to provide alternative applications so that the junction can operate optimally. This data collection is then used in the analysis to determine the performance of the junction using the Indonesian Road Capacity Manual (MKJI 1997). The results obtained from the research show that the performance of the signalised intersection Jl. Yos Sudarso - Jl. Galaxy for the existing conditions is in the ITP F category with a value of the average intersection delay = 258 smp / sec, the value of the degree of saturation on the south approach = 1.377, on the east approach = 0.663 and on the west approach = 0.893. The degree of saturation exceeds the value recommended by MKJI, which is <0.85. On the basis of this study, the recommended solution is to change the 3-phase arrangement to 2-phase and to prohibit right turns on the western approach, as well as to rearrange the time in the intersection traffic cycle at the intersection of Jl. Yos Sudarso - Jl. Galaxy in order to achieve the ITP (C) value.

Abstract

The Service Entrance (SE) is the end of the power distribution system to the customer, from where the quality of the voltage distributed by PT PLN (Persero) can be seen. At PT PLN Rayon Pedan, there are many report from customers as well as inspection teams and technical services about the voltage drop in customers' homes. One of them is from Dukuh Nanggulan, Cawas Klaten. After being inspected by the technical department of PLN Rayon Pedan, there were many house connections that did not comply with PLN Standard 56-1 in 1993. The house connection can cause voltage drop and carrier loss. According to the measurement at the time of the peak load, the voltage at the end of the line dropped by 178.21 volts. This violates the tolerance limits specified by PLN in SPLN 1 1995 regarding the standard voltage, which is -10% for the lower limit or as much as 198 volts from the nominal voltage standard PLN 220 V. To overcome the voltage drop and loss caused by the service entrance, the authors of the series perform improved planning by adding new low voltage networks as well are configuring old service entrancesusing ETAP 12.6.0 software to compare results before and after reconfiguration of the service entrance.

Abstract

Sugar factories (PG) can contribute to efforts to reduce greenhouse gas (GHG) emissions in accordance with the obligations of the Kyoto Protocol and the Paris Agreement. Closed PG systems have the potential to minimise waste and reuse production residues, making them a sustainable solution for reducing environmental impacts and increasing economic benefits. This study models the yield and economic benefits of closed system PG using Life Cycle Assessment (LCA). The aim of this research is to analyse the economic benefits and carbon credits of closed-system sugar production using LCA. The research methodology is descriptive, involving the calculation of carbon credits based on the Kyoto and Paris Agreements. The LCA method is used to assess carbon emissions. The use of bagasse as cogeneration fuel produces an excess of 5 GWh/milling season of electricity, which can meet the electricity needs of 6944 households during the milling season or 3472 households per year. PG X produces 667.5 million liters of clean water during the milling season, which can meet the drinking water needs of 61,805 people throughout the year.
