Abstract

Keamanan adalah aspek yang sangat penting untuk mencegah terjadinya tindak kejahatan di dalam lingkungan, terutama tempat tinggal masyarakat itu sendiri. Permasalahan yang terjadi dalam masyarakat adalah sama yaitu pencurian atau pembobolan pintu rumah yang mengakibatkan kerugian yang sangat besar bagi masyarakat. Salah satu kerugian masyarakat karena kejahatan pencurian adalah hilangnya barang-barang pribadi seperti: laptop, hp, uang dan lain-lain. Teknologi untuk mengindari pencurian di rumah diperlukan teknologi pengaman salah satunya kunci pintu rumah itu sendiri. Berdasarkan hasil percobaan yang dilakukan Pembacaan sensor sidik jari ( fingerprint ) bekerja dengan baik, dari 100 kali percobaan didapat tingkat kegagalan sebesar 3.91 % persen ini disebabkan oleh posisi jari yang tidak tepat atau permukaan fingerprint kotor. Dan tingkat keberhasilan pembacaan fingerprint ialah 97.69 % persen. Perangkat android dan perangkat wifi esp8266 dapat terkoneksi dengan baik pada rentang jarak antara 0 hingga 23 meter. Hasil pengujian yang dilakukan sebanyak 100 kali untuk membuka pintu terjadi kegagalan sebanyak 6 kali dan berhasil sebanyak 94 kali, hal ini membuktikan bahwa alat yang dirancang ini bekerja dengan baik.

Abstract

Pengolahan Tandan Buah Segar (TBS) menjadi Crude Palm Oil (CPO), merupakan suatu proses ekstraksi minyak kelapa sawit yang dilakukan PT. Perkebunan Nusantara V Pabrik kelapa Sawit (PKS) Sei Pagar. Kegiatan pengolahan TBS di PKS dengan kapasitas terpasang 30 ton TBS per jam berlangsung 24 jam per hari. Dengan beban kinerja yang begitu panjang aktivitas pengolahan sering mengalami hambatan yang disebabkan oleh gagalnya mesin produksi steam dalam menjalankan fungsinya hingga menyebabkan menurunya hasil pengolahan. Penelitian ini bertujuan untuk mengetahui analisa keandalan sistem instrumentasi boiler dan penerapan jadwal perawatan bagi komponen yang mengalami kegagalan terutama komponen yang kritis untuk memperkecil waktu down time. Hasil analisa dari kedua boiler yaitu pada boiler No. 1 nilai keandalan sebesar 99,78 % dan pada boiler No 2 sebesar 99,96 %. Dari analisa nilai MTBF dapat diketahui bahwa waktu operasi semua komponen yang dapat menyebabkan kerusakan yang paling sering terjadi pada boiler No. 1 terdapat pada komponen electric pump dengan nilai MTBF sebesar 454,73 dengan 7 kali mengalami kegagalan, maka jadwal perawatanya setiap 19 hari kerja kerja, sedangkan pada boiler No. 2 terdapat pada komponen electric pump dengan nilai MTBF sebesar 216 dengan 14 kali mengalami kegagalan, maka jadwal perawatanya setiap 9 hari kerja kerja.

Abstract

The pull-up and push-up counter device is designed to automatically count the number of pull-up and push-up repetitions performed by an individual. The problem faced is errors in performing pull-up and push-up movements and the limitation of manual counting, which solely relies on remembering the total count of movements from the previous day. This can lead to uncertainty in monitoring the progress of the exercise. The purpose of this research is to develop a pull-up and push-up counter device that utilizes the Internet of Things (IoT) and is connected to the Blynk application on a smartphone to provide ease and accuracy in recording exercise repetitions, eliminate the difficulties of manual counting, and provide real-time data to users for monitoring and tracking their exercise progress. This device is equipped with an MPU 6050 sensor that can detect changes in angular acceleration in the arms. The methodology applied in this research is the Research and Development (R&D) method, which includes product efficiency testing and product development. The research results show that this device can connect to Wi-Fi networks effectively, and its status can be viewed through the LCD display on the device as well as the Blynk application, which displays an online status when the device is connected and an offline status when it is not. The MPU 6050 sensor works effectively in detecting the user's inclination at the specified angles, forming a 70 angle for pull-up movements and a 90 angle for push-up movements. Testing was conducted using a comparative method between manual counting and counting using the device. In the tests conducted at three different movement speeds, it was found that fast movements in pull-ups resulted in a difference in counting of 7.6%, while in push-ups, there was a difference in counting of 6.8%. These differences were due to the device's inability to detect the intended angles of inclination accurately. On the other hand, movements at moderate and slow speeds showed a 0% difference in counting for both pull-ups and push-ups.

Abstract

The growth of technology has an important role in supporting medical equipment facilities, especially for tools for providing compression or cardiopulmonary resuscitation (CPR). CPR is a first aid measure for victims of sudden cardiac arrest in which cardiac compression is carried out for 4 cycles, each cycle consisting of 30 compressions. CPR given manually can endanger the victim due to certain factors such as insufficient or excessive pressure applied. So that the above can be realized, a tool is needed that can make it easier for someone to check their heart rate on their skin quickly and effectively. The MAX30102 sensor is a sensor that can calculate heart rate. This research aims to create an optimal automatic cardiopulmonary resuscitation device to help victims continue to breathe. This RJP tool uses a Nema 23 stepper motor as the driving motor, the motor driver uses a TB6600 driver as the motor controller. During testing, 1 minute produced 103 compressions and 30 compressions in 18 seconds. The torque strength of the stepper motor is only capable of lifting a load of 7 kg, the torque produced is 2.06 Nm. This research also uses sensors to detect heartbeats. This allows the device user to monitor the patient's heartbeat while undergoing RPJ.

Abstract

PT. Indah Kiat Pulp and Paper Perawang is a company that prioritizes paper production. There is a crucial unit known as the lime kiln within the company. Issues occurring within this unit often disrupt the overall production process. Therefore, conducting reliability analysis on the instrumentation of this unit is highly important. This research utilizes the Reliability Centered Maintenance (RCM) method. The objective of this study is to determine which devices within the lime kiln are most vulnerable to problems by calculating the Risk Priority Number (RPN) for each component, evaluating the reliability level of these devices, and providing optimal maintenance schedule recommendations. The research findings indicate the sequence of RPN values for lime kiln instrumentation from highest to lowest as follows: temperature sensor 336, on-off valve 288, flow transmitter 252, control valve 245, proximity sensor 240, pressure gauge 216, sensor indication of motorized damper 210. Furthermore, the reliability values of each instrumentation did not meet the threshold set by the Indonesian Industry Standard (SII), which is 0.7. Therefore, it can be concluded that maintenance action is required for these instrumentation devices. Maintenance schedule recommendations for temperature sensor are 252 days, on-off valve 294 days, flow transmitter 293 days, control valve 251 days, proximity sensor 293 days, pressure gauge 352 days, and sensor indication of motorized damper 353 days.Keywords – Keandalan, Instrumentasi, Maintenance, Lime kiln, RCM.

Abstract

 PT. PLN Nusantara Power UP Tenayan is a company operating in the power generation sector and focuses on operating PLTUs Tenayan, Indonesia. One part of the machine that influences the operation of the generator is the boiler feed pump. Lack of optimal boiler feed pump instrumentation often results in failure in operating activities. This research uses the Failure Mode and Effect Analysis (FMEA) method with the research objective of finding out the causes of failures that occur, identifying the type of failure, and determining the RPN value and the impact that occurs. The analysis results, it shows that the Boiler Feed Pump instrumentation components still meet operating standards because the Risk Priority Number (RPN) value is below 200, even though the Speed Sensor has a fairly high RPN value but is still in the reliable category, the result of identifying the type of failure that occurs is that the indicator reading is not actual, the component is not functioning, the highest RPN value for the Boiler Feed Pump component is the Speed Sensor component with an RPN value of 160 and the lowest RPN value is for the pressure indicator component with an RPN value of 30. The most important recommended action for the Speed Sensor component is to carry out maintenance for 1 month very.Keywords – Boiler Feed Pump, FMEA, Keandalan, Pembangkit, RPN.
