Abstract

The apple cider vinegar fermentation process requires careful monitoring and control of variables such as pH, alcohol content, and amount of acetic acid. This research adopts Fuzzy Logic Control by utilizing the MQTT communication protocol, pH, alcohol and water pump sensors, as well as solenoid valves and DC motors as actuators. This Internet of Things (IoT) based solution provides real-time monitoring information on the fermentation process. The results showed that the test system succeeded in maintaining a stable pH of around 3.9-4.0 during the initial stages of fermentation, while industrial data showed greater variations. Alcohol content increased consistently in the test system, in contrast to the spike on day 7 in industry data. At the formulation stage, the pH dropped to 3.68 in the test system, while the industry maintained 3.70. At medium and slow mixing stages, the test system showed a significant decrease in pH and a consistent increase in alcohol. At the harvest stage, the pH was lower in the test system compared to industrial, with slightly higher alcohol content. Test results show that the implementation of this system can reduce the fermentation process time by up to 2 days faster compared to conventional methods. This conclusion shows that IoT-based systems are able to provide better control and monitoring than conventional systems, so they have great potential for wider adoption in the apple vinegar fermentation industry to increase production effectiveness.

Abstract

Porous concrete is commonly used in road linings with minimal traffic, parking areas, pedestrian paths, and parks. The strength of porous concrete depends on the size of the aggregate and the correct composition of water and cement. The objective of the study was to analyse the effect of cement water factor in uniformly graded porous concrete on compressive strength and permeability in uniformly graded porous concrete on permeability values. The relationship between the compressive strength of concrete tends to decrease as the value of cement water factor increases. The water-cement factor strongly influences the permeability value. The greater the value of cement water factor, the smaller the permeability of uniformly graded porous concrete, this is due to the deposition of cement water at the base of the slab. The use of super plasticizer (SP) in porous concrete accelerates the pavement process, but does not improve permeability. cement water factor 0.35 with a 28-day treatment period obtained a Slump test value of 178 mm, cement water factor 0.5 of 192 mm, cement water factor 0.6 with a 28-day treatment period obtained a Slump test value of 196 mm. while porous concrete with a cement water factor of 0.35 has an average compressive strength of 6.13 Mpa, while a cement water factor of 0.50 has an average compressive strength of 5.47 Mpa, and a cement water factor of 0.60 has an average compressive strength of 5.00 Mpa.

Abstract

This qualitative study investigates the challenges faced by new engine officers in maritime settings, focusing on their transition from theoretical learning to practical engine maintenance. Through semi-structured interviews with experts in marine engineering and engine management, the research identifies significant gaps between theoretical knowledge acquired in classrooms and the practical skills required aboard ships. Key findings highlight the need for educational reforms, including increased practical training hours, curriculum adjustments to enhance relevance, and integration of simulation technologies. Participants, comprising professional engine masters, endurance managers, and maritime educators, unanimously advocate for a more hands-on approach to training that prepares cadets to handle complex engine maintenance tasks effectively. Simulation technologies, particularly virtual reality simulations, emerge as crucial tools for bridging the gap between theory and practice. They provide realistic environments for cadets to simulate diverse operational scenarios and develop critical decision-making skills without exposing them to actual risks. The study concludes with recommendations for collaborative efforts between educational institutions and industry stakeholders to implement these reforms, ensuring a competent and prepared workforce capable of meeting the dynamic challenges of modern maritime operations.

Abstract

The Raya Blega Street intersection is one of the intersections with a relatively high vehicle volume in Bangkalan Regency. There is no APILL (Traffic Signaling Device) available at this intersection, so it has an impact on traffic flow at the intersection. The existence of the market causes many side obstacles which reduce the optimal performance of the intersection. This condition causes the intersection to experience traffic delays, especially during peak hours such as when leaving work or when leaving. In this research, researchers want to identify the problem of congestion at the Raya Blega street-Rajawali street intersection by calculating and analyzing the performance of the Raya Blega street-Rajawali street intersection using the PKJI 2023 method so that it can be used as a benchmark for assessing the performance of unsignalized intersections and assisting related parties in handle problems at the intersection and it is hoped that they can handle the problems that occur at the intersection so that it can create security and safety for passing users.In this study, the highest value was obtained for existing conditions on Monday, April 29 2024, at morning peak hours (07.00-08.00) at approach point A (east Raya Blega street) with an intersection capacity value of 2297,96 smp/hour and the value obtained The degree of saturation is 0,36 and the delay value is 8.44 sec/smp so it is included in Level of Service B. So the status of the Raya Blega street-Rajawali street Bangkalan Regency intersection is still suitable to be maintained.

Abstract

Semarangan vernacular houses mostly have acceptable thermal performance, primarily related to the roof design and its elements. However, some developments associated with the quality of comfort have already been in progress. We found modifications with an alternative opening in the roof. Testing is needed to determine whether this alteration of a vernacular house with roof modifications is suitable to synchronize to nature and culture for its sustainability. This research aims to assess the quality of the modification for the thermal and energy performance of Semarangan vernacular houses in responding to climate change based on innovation. We utilize an energy audit simulation using the SketchUp software and the Sefaira plugin extension to measure thermal shape and variables. The focused study analyzes the thermal performance of buildings through analysis of the building envelope and building shape from a conceptual model. We discover that vernacular modifications do not reveal any extreme differences. Further research is needed to examine some other types of modifications further. We have to ensure that any modification maintains the quality of the house's performance and even have to increase it.

Abstract

PT Mass Rapid Transit Jakarta operates a mass transportation system from Lebak Bulus Station to Bundaran HI. One of the traction substations is located in Cipete Raya, with a voltage rating of 20kV/1.2kV. A critical piece of equipment in this substation is the traction transformer, with a capacity of 4850 kVA/2x2500 kVA. The purpose of this study is to predict the service life of the Cipete Raya traction transformer based on temperature and load using the linear regression method. This study employs direct observation, analyzing load data from traction transformers 1 and 2 at Cipete Raya from January 2022 to June 2024, along with transformer temperature measurements. Secondary data include the technical specifications of the Cipete Raya traction transformer. The linear regression analysis for transformer 1 yields the equation y = 687.42 + 11.97x, indicating a 5.75% annual increase over the next 5 years, with a very strong correlation coefficient of R = 0.919. For transformer 2, the equation is y = 815.4543 + 6.488x, showing a 3% annual increase, with a strong correlation coefficient of R = 0.814. Based on the transformer aging calculations for June 2024, Transformer 1 has a per unit aging value (V) of 0.0014 and an estimated service life (n) of 407.689 years, while Transformer 2 has a V of 0.0012 and an estimated service life of 496.77 years. The aging model evaluation using MAPE shows that the prediction accuracy for transformers 1 and 2 is 6% and 3%, respectively, indicating excellent modeling performance.

Abstract

Many rivers in Indonesia had very poor water clarity due to a mixture of dirt and mud in the water. Polluted rivers were often found in areas near settlements, where household waste that flowing into rivers made the water look dirty and turbid. Pollutants dissolved in water will bind to small particles and settle at the bottom of the river, due to sedimentation. This research designed a device to detect sediment volume in the rivers. This device used an ultrasonic sensor type DYP-L04 and a rotary encoder for calculating volume, with Arduino Mega 2560 R3 as a processor. There is a PG45 motor that was used to set the motor speed to be constant. This ultrasonic sensor works based on the Arduino programming algorithm that has been designed, so that the device can measure sediment volume optimally. The results of this research showed that the device could determine the volume of sediment with the average error score less than 10 %.
