Abstract

In this research, it is intended to identify the concentration of soot in the exhaust emissions of the L-300 diesel engine by adding an additional substance in the form of methanol CH3OH. The research method in this study used an experimental method with the help of a smoke tester used to test the soot concentration in exhaust emissions of diesel motorized vehicles. The experiment was carried out at night using different mixtures and where each mixture will be carried out 8 times to collect data. Experiments used a smoke tester to test soot emissions on: fuel not mixed with methanol additive (M0D100), 5% methanol mixture (M5D95), 10% methanol (M10D90), 15% methanol mixture (M15D85). After carrying out the research and data processing, it was obtained that the M0D100 mixture had a soot emission concentration of 36.52%. The M5D95 mixture decreased the concentration of exhaust emissions to 31.05%. Then in the M10D90 mixture, the soot emission concentration decreased to 27.17%. whereas in the M15D85 mixture the soot concentration increased to 33.76%.

Abstract

The habit of pedestrians in using the road when crossing the road is in the spotlight because it will cause traffic jams so that they are prone to accidents. No road user wants to experience such an accident, whether it is a minor accident or an accident that is fatal and leads to death. Pelican crossings are made to minimize pedestrian accidents, but this facility does not guarantee that accidents will not occur. Problems arise when pressing the crossing button will create congestion and noise due to the notification sound of the crossing. When someone wants to cross it will result in the accumulation of vehicles around because they are waiting for irregular pedestrians to cross. The purpose of this research is to design a pedestrian Puffin Crossing advance simulation that is more adaptive and safe. The research was conducted by making a prototype using a microcontroller and several sensors which will later be used as a medium for interaction between drivers and pedestrians. The results of the prototype research can work well and in accordance with the function of each component. The recommended minimum number of pedestrians is 4 waders, the minimum required waiting time is 5 seconds, while the crossing time is conditioned based on pedestrian sensor readings at the zebra cross.

Abstract

The real estate sector's economic resilience, which is essential for the recovery of the economy following the COVID-19 epidemic, is significantly influenced by financing. However, COVID-19's effects mean that financing cannot operate as previously agreed upon within the allotted time, which causes many debtors to go into default and produce bad debts or non-performing financing. Errors in the application of financing procedures might also result in non-performing financing. Problem funding is attempted to be saved by enforcing bank policies that currently exist. The goal of this discussion is to determine how the bank BSI Bank KCP Bogor Pajajaran Bantarjati's procedures, comparative financing conditions during and after COVID-19, and the resolution of problematic financing have shown a positive trend because it has been successful in lowering the number of customers who restructured from 30% to 0%, non-performing financing from 14% to 7%, and current financing from 56% to 93% during post-COVID-19. The number of customers whose financial situations improved and they were able to pay off their loans also contributed to the upward trend. This demonstrates the efficacy of the financing guidelines and practices put in place by Bank BSI KCP Bogor Pajajaran Bantarjati in an effort to keep the bank in good standing following COVID-19.
