Abstract

The influence of high temperature and exposure to ultraviolet (UV) radiation from sunlight, rain, and humidity causes damage to the composite material and consequently, reduces its mechanical performance. Weathering experiments can be carried out outdoors or under laboratory conditions. Material degradation tests can be carried out directly using natural conditions or laboratory test equipment that artificially simulates natural conditions. An automatic temperature control system is needed to keep the setpoint stable during the degradation test. The controller on the system uses Arduino based on Proportional, Interval, and Derivative (PID). The test was carried out by running the system with different PID parameter values three times to obtain the most optimize-tingling results in maintaining the setpoint at steady state conditions. Based on the results of tests that have been carried out with a setpoint of 40⁰C, the most optimal results are obtained with values of Kp=10, Ki=20, and Kd=30. The average temperature is 40.02⁰C with an average error percentage of 2% and an average accuracy rate of 98%.

The use of a manual bottle labelling tool also results in the production results being unmeasurable. This study aims to develop a manual bottle labeling tool into a semi-automatic labeling tool by creating a control system that can control the tool. The tool control system that will be made is based on the Arduino Uno microcontroller. The use of the Arduino Uno microcontroller can make it easier to control some of the electronic components needed in the manufacture of control systems. Arduino microcontroller is programmed using Arduino IDE software with C++ language. In this study the programming logic used is the logic of the if else condition function. The programming logic of the if else condition is used to refer to the control system that will be made to contain many decision-making statements from a condition. Before developing the tool, this research started from the observation process which aims to find out the basic working principle of the manual bottle labeling tool. Furthermore, from the results of these observations, a program or control system is made which aims to obtain the results of tools that work semi-automatically. The result of this research is an Arduino program that can control ultrasonic sensors, TCS3200 color sensors and stepper motors on semi-automatic bottle labeling tools. The average time for labeling semi-automatic tools is 3.262 seconds and the average time for labeling manual tools is 5.088 seconds. Based on the results of the production carried out, the manual bottle labeling device is capable of producing 707 bottles per hour and the semi-automatic bottle labeling device is capable of producing 1,103 bottles per hour.

Abstract

Drum Roller adalah mesin yang dirancang untuk pengujian ketahanan ban mobil setelah proses produksi. Peralatan  berputar, dan realisasi diagnosis waktu nyata dari kesalahan getaran frekuensi umum sangat penting untuk memantau kondisi Drum Roller. Getaran yang tinggi dapat merusak bagian-bagian penting mesin dan mempengaruhi kualitas ban. Maka dengan itu, dilakukannya analisis getaran untuk mengidentifikasi kerusakan dengan Metode Fast Fourier Transform (FFT)  dan Metode Short Time Fourier Transform (STFT). Pemrosesan sinyal dilakukan dari input hasil pengukuran getaran berupa data domain waktu pada MATLAB kemudian metode FFT dan STFT diterapkan menggunakan fungsi filter jendela Hanning. Selanjutnya memvalidasi hasil analisis kerusakan. Berdasarkan hasil pengukuran getaran didapatkan sumber getaran terbesar pada posisi radial yaitu getaran yang dihasilkan sebesar 96 μm RMS. Dari grafik spektrum dan spektogram Fourier transform radial dan axial keduanya dapat disimpulkan bahwa adanya indikasi unbalance pada impeller dengan frekuensi 6.7 Hz yang menunjukkan satu kalinya frekuensi Drum Roller. Berdasarkan standar analisis getaran Displacement (ISO 10816-3), getaran Drum Roller masuk pada Zona C, bermakna mesin hanya diizinkan beroperasi dalam waktu singkat. Hasil analisis bahwa Drum Roller mengalami unbalance terbukti benar dengan turunnya nilai getaran menjadi 18 μm RMS.

Abstract

Low Temperature Economizer (LTE) is a support system for boilers with a capacity of 1000 MW at unit 1 PLTU in Serang which serves to increase the temperature of the feed water by utilizing the heat from the exhaust gases. In 2021, LTE in boiler unit 1 experienced a disruption so that LTE had to stop operating. This has an impact on boiler efficiency and production costs at unit 1 PLTU in Serang, especially on fuel costs. This research was carried out by collecting data on DCS and collecting data in the field, then data processing was carried out. The efficiency calculation method used is direct efficiency calculation, with boiler data retrieval when LTE leaks occur so that LTE stops operating compared to boiler operating conditions with LTE after repair. The coal used is lignite type coal which has a calorific value below 4500 kCal. Boiler efficiency when LTE stops is only 76.04%. This value is smaller than when the boiler operates with LTE which reaches 85.12%. The repair of LTE pipeline leaks can save coal usage by more than 4 tons per hour. Production costs on the use of coal can be reduced to more than Rp. 80,000,000 per day.Keywords: Low Temperature Economizer, Boiler Efficiency, Production Cost

Abstract

The Pelton turbine is a type of water turbine whose working principle utilizes the potential energy of water which is converted into kinetic energy through a nozzle. The fluid coming out of the nozzle push the bucket and rotates the Pelton turbine which ultimately produces electrical energy. Micro-hydro power plants that usually use Pelton turbines need to be developed to remote villages to meet electricity needs in Indonesia. Pelton turbine buckets, which are usually made of metal, are not only difficult to manufacture so they have to be specially ordered, but also easy to rust. Therefore, in this study, the bucket was made easier and simpler using an epoxy resin composite material reinforced with palm fiber. This makes it lighter and more corrosion resistant. The results of this study indicate that the epoxy composite fiber reinforced with 9% fiber volume has a higher tensile strength than the volume fraction 0%, 3%, 5%, 7%. The maximum tensile strength for 9% fiber content is 32.6054 N/mm2 . Then the tensile strength results are applied to the Pelton turbine bucket geometry with laboratory scale sizes that have been varied into 3 different size models in: bowl width (b), bowl height (h), and bowl height (h1). Based on solidworks simulation results all bucket models in this study have a factor of safety above the minimum limit of 6, therefore this composite can be used as a Pelton turbine bucket material. The first bucket version has a minimum factor of safety 6.656, the second bucket version has a minimum factor of safety 6.756, the third bucket version has a factor of safety 6.945.

Abstract

A Microhydro Power Plant (MHP) with hydrocoil turbine in Sukajaya Lembang Village, Bandung, West Java, has been successfully designed. However, the velocity of the water flow after exiting the hydrocoil turbine is still relatively high, so there is still a lot of wasted flow energy before it can be converted. Like other reaction turbines, the hydrocoil turbine requires a draft tube in order to maximize its energy conversion process. Thus, the purpose of this research is to determine the type of draft tube based on the head recovery value and performance of the hydrocoil turbine for the MHP system. This determination process involves 3 stages: 1) evaluation of the performance of the hydrocoil turbine that has been installed with three types of draft tubes, namely conical straight, curved elbow, and simple elbow, by Computational Fluid Dynamics (CFD), 2) calculation of the head recovery of the three types of draft tubes, and 3) determination of the best draft tube based on the head recovery value and performance of the hydrocoil turbine. In stage one, the type of analysis used is steady state with the SST k-ω turbulence model, to capture turbulence in the penstock pipe and near the turbine blades. As the results, the highest hydrocoil turbine efficiency with all three types of draft tubes installed, is at a rotational speed of N=1100 rpm. The highest efficiency for the hydrocoil turbine with conical straight, curved elbow, and simple elbow draft tubes are 90.48%, 90.18%, and 91.26%, respectively. Meanwhile, the head recovery at rotational speed N=1100 rpm for conical straight, curved elbow, and simple elbow draft tubes are 1.627 m, 1.866 m, and 4.097 m, respectively. Thus, the simple elbow draft tube is the best to use in this MHP system because it has the highest head recovery and efficiency values.

Abstract

Kursi plastik merupakan furnitur yang sering dijumpai di masyarakat umum karena mudah digunakan untuk dibawa ke mana-mana dan juga menghemat penyimpanan karena dapat ditumpuk. Dalam penggunaan sehari-hari, kursi plastik sering mengalami kerusakan. Untuk kinerja konstan yang ideal, kursi plastik harus memiliki kapasitas beban maksimum yang jauh lebih besar dari beban operasi, sehingga tegangan tidak merusak kursi plastik dari waktu ke waktu. Penelitian ini mengacu pada Analisis Elemen Hingga, analisis tegangan Von-Mises, dan kegagalan desain kursi plastik. Analisis dilakukan pada struktur pembebanan statis di Solidworks 2021, dengan beban sebesar 1200N yang bekerja ke bawah (sumbu Y) di sepanjang empat kaki kursi plastik yang diposisikan tetap. Analisis dilakukan pada tiga alternatif desain, yaitu desain kursi plastik tanpa rusuk penguat, kursi plastik dengan rusuk penguat model X, dan kursi plastik dengan rusuk penguat model kotak. Analisis dilakukan dengan menggunakan bahan plastik ABS. Setelah dilakukan simulasi didapatkan nilai tegangan von-mises dari ketiga alternatif desain sebesar 38,30 MPa; 30,81 MPa; dan 8,86 MPa dengan batas tegangan yang diizinkan oleh material ABS adalah 28,00 MPa. Nilai faktor keamanan dari ketiga alternatif desain adalah 0,73; 0,91; dan 3.16. Batas aman minimum untuk beban statis adalah 1,25. Dengan demikian alternatif desain yang memenuhi persyaratan adalah kursi plastik dengan rusuk penguat model kotak dengan nilai faktor keamanan 3,16. Adapun dua desain lainnya tidak aman. Lokasi tidak aman terjadi di sudut pangkal kaki kursi plastik.
