Abstract

This research leads to monitor condition of cleanliness and suitability of clean water is very important to support human life daily. Clean water will make us feel safe and comfortable when using it. There are several particles and materials contained in water, even in the clean water category. Several parameters that are often measured as benchmarks for the level of water cleanliness include the acidity level of the water (pH level), the number of particles or substances in the form of organic and non-organic compounds in the water or often called TDS (Total Dissolve Solid) and the level of water turbidity or often called turbidity. In this research, monitoring will be carried out on water located on the coast, for example brackish water, on the levels of these three water parameters so that the water can be categorized as suitable for use at least for MCK (Bathing Washing Toilet) for people who use this water. In this research, a filter method was used to purify water using palm fiber, silica sand, zeolite stone and activated charcoal. Several test results carried out showed an increase in the acidity level of the water from 6.4 NTU to 6.78 NTU, a decrease in the level of impurities in the water or TDS from 1180 ppm to 1104 ppm and a decrease in the level of water turbidity or turbidity from 3.2 to 1.16. The test data shows that the filter can work quite well even though the decrease that occurs is not very significant, especially in the TDS level value and this value can be monitored well on the LCD or on the smartphone application.

Abstract

Photovoltaic power plants have drawbacks, one of which is that it is very dependent on the ntensity of sunlight and the surface temperature of the solar panels. In this case it takes a battery to be able to cope with photovoltaic at night.The battery has a function as a means of storing electrical power generated by photovoltaic and supplying power to the load. Therefore, we need a tool that ican regulate the power generated from several solar panels to fulfill the required load power.n this test the Arduino Mega2560 icontrol device was used with the PID control method as the brain of the design that regulates the output power of the solar panel so that it remains stable in fulfilling the load power. From the results of this test, the results show that this tool can share power and regulate ipower ias needed with pid control using the Trial and Error method in each solar panel with a percentage of 60% and 40% in stable power with set point i 1 14V and set point 2 10V with.the maximum power of 10mW obtained from each solar panel is then used as a graph ifrom ithe test results.

Abstract

Based on the increasing need for electricity for the community, especially in the Bangka Belitung region, which still uses a lot of expensive fossil energy (generators), so it is still a cost constraint for people living in remote areas that have not been electrified. So it is necessary to innovate in making electricity that utilises natural resources (water). However, the problem is that water sources in some places have erratic water discharge. Therefore, in this research it is proposed to make a portable hydropower plant so that it can be moved in a place that has a high water discharge that can monitor the rpm, voltage and current of the generator and battery and is expected to be used as a cheap and environmentally friendly alternative power plant. The methodology in making this hydropower plant uses a 100Watt DC generator with a 12-bladed breadshot turbine type and is controlled using LM393 sensors and INA219 sensors with a monitoring system using the Blynk application by utilising IoT-based technology. The test was conducted by testing the effect of generator rpm speed on generator current and voltage, battery charging and discharging time, and testing the monitoring system using the Blynk application. From the test results, it is obtained that the minimum generator rpm that must be achieved when charging the battery is 425 rpm with the power obtained of 12.19Watt. Charging a 50 Ah capacity battery at the hydropower plant takes 6 hour and 38 minutes with a charging current of 6,7A. While for battery discharge using a 12V 75Watt lamp load takes 7 hours 25 minutes. The generator monitoring system using the Blynk application works well in displaying the same measurement results on the LCD screen with an accuracy value of 100%.

Abstract

Public Street Lighting (LPJU) is a source of lighting that helps road users when crossing the road at night. But there are still many LPJUs that light up during the day in the absence of a control system. Therefore, this study will discuss the LPJU automatic monitoring and control system using LoRa as a remote communication device. The methodology on this system uses LDR sensors as input and is processed by esp32 devkit v1 with lora communication as data transmission, and the monitoring system uses the website display on localhost phpmyadmin. The results of LoRa communication testing in LOS conditions with a distance of 100 m to 2000 m were successfully sent and received well from LPJU to a laptop even though there was a delay in data reception, while in Non-LOS conditions LoRa communication was less than optimal because there were delays and obstructions when receiving data with a distance of 1 meter to 30 meters. LPJU can be activated and disabled automatically using LDR as an automatic salkar contact, and monitoring results can be displayed on a website page with an internet connection.

Abstract

Livestock farming is one of five agricultural subsectors. Animal husbandry is the activity of keeping livestock for cultivation and gaining profits from this activity. Broiler chickens are a type of commodity in the livestock sector that produces food from livestock and has quite potential economic value. The aim of this research is to help breeders' activities in controlling and monitoring livestock continuity. Apart from that, this research is also to produce ideal temperatures in the chick cage so that heat stress conditions do not occur in the chicks. Based on the sensor and thermometer test results for temperature measurements in the table, it can be concluded that the average percentage of measurement results is normal. The data that has been taken shows that the LM35 and DHT11 sensors have good temperature detection capabilities. Therefore, this sensor can be used well to detect the temperature needed in this final project.

Abstract

 A system for detecting the presence of mosquito larvae can be used as a solution to find out whether the air reservoir is healthy or not. This mosquito larva detection system uses several measuring parameters, including the distance between the object of the mosquito larva and the camera, air turbidity/light conditions, and the number of mosquito larvae in the air protector. From the results of tests carried out on the detection distance parameters, the results showed that the system could detect the presence of mosquito larvae within a distance of 5-15 cm in clear air/bright light conditions with a detection success rate above 80%. In the same test, but with cloudy air/dark light conditions, detection went well but a detection error occurred at a distance of 15 cm, namely the system detected objects other than mosquito larvae as mosquito larvae. This is due to several factors, including the lack of variation in the dataset, the detection system is carried out in real-time (in the form of video capture) and the camera specifications used do not meet the minimum value required by the computing system.

Abstract

Dump truck LGMG CMT 96 is employed by PT Ansaf Inti Resources for overburden transportation, operating up to 22 hours per day. In the unit coded DT 060-032, a transmission failure was detected at 2,143.5 hours, significantly below the company's target of 20,000 hours. The symptoms of the failure included the activation of the transmission warning indicator, fault codes, excessive jolts during operation, transmission overheating, and gear shifting failures. This study identifies the primary causes of the failure through monitor checks, visual inspections, historical maintenance data, the Machine Inspection Program (PPM), the Lubricant Analysis Program (PAP), and transmission overhaul results. The applied failure analysis method revealed brittle fracture of the lock-up clutch and excessive clutch wear due to deformation, heat spots, and blue temper. Operational errors were concluded to be the main cause of the transmission failure, leading to clutch slip and the appearance of fault code F:191 S:8.

Abstract

Fire, smoke, and gas leak detection systems are among the most influential aspects of security, including on Tugboats. This detection system usually cannot detect in real-time. With the development of Internet of Things (IoT) technology, it is expected to be used for a more accurate and real-time detection system. The purpose of this final project is to create a system that uses the Internet of Things (IoT) as an early warning message in the event of a fire, smoke, and gas leak on a Tugboat. The methodology for completing this final project is data collection and literature study in the initial stages carried out in making hardware with the selection of components used by the function of this final project tool. In the programming process, the radius method is used to detect how far the sensor distance can be detected in detecting using the Internet of Things (IoT) as a warning message in case of fire, smoke, and gas leakage. Thus, this final project produces a fire, smoke, and gas leak detection system in real-time and monitors using a smartphone. This system can be used in various environmental places on the ship, such as the kitchen, capt room, mess room, and command room, to detect early accidents on the Tugboat.
