Abstract

Abstrak – Energi surya merupakan suatu energi alternatif yang tersedia dalam jangka waktu yang lama, sementara sumber energi utama yang digunakan saat ini mempunyai keterbatasan. Divais elektronik yang digunakan yaitu panel surya, panel surya adalah komponen semikonduktor yang dapat mengkonversi energi surya menjadi energi listrik. Namun, karena tingkat penyinaran energi surya yang berbeda-beda menyebabkan daya keluaran dari panel surya bervariasi dan tidak maksimal, maka dari itu diperlukannya model yang menyerupai karakteristik sel surya sebenarnya, sehingga kita dapat melakukan percobaan sederhana dari beberapa data untuk mencari tahu bagaimana untuk mendapatkan performa semaksimal mungkin dan mempertahankannya. Panel surya memiliki karakteristik yang non-linear, hal ini membuat kita sulit untuk mendapatkan titik maksimum dari panel surya tersebut, sehingga diperlukan pemodelan dari panel surya untuk mendesain dan mensimulasikan algoritma Maximum Power Point Tracking (MPPT) untuk menjaga titik kerja panel surya. Sebagai pendukung sistem MPPT, digunakan DC-DC Boost Converter sebagai pengatur tegangan keluaran dari panel surya untuk menjaga titik kerja panel surya tetap pada titik MPP. Adapun hasil dari penelitian yang dilakukan sistem yang dirancang berjalan dengan baik. Terjadi kenaikan rata-rata nilai tegangan keluaran sebesar 51.22 %, dari rata-rata sebesar 19.84 Volt sebelum pemasangan sistem MPPT menjadi 40.67 Volt setelah pemasangan sistem MPPT saat kondisi iradiasi matahari dan temperatur yang berubah-ubah, dan juga dapat mempertahankan tegangan keluaran dari modul panel surya disekitar nilai maksimum yang diinginkan yaitu sebesar 40 Volt. Kata Kunci : DC-DC Boost Converter,MPPT, Panel Surya, Sliding Mode Control

Abstract

Teknologi yang tepat diperlukan manusia agar dapat meningkatkan efisiensi kerja serta keselamatan sumber daya manusia itu sendiri. Kendali PID tidak dapat bekerja dengan baik apabila terjadi ketidakpastian dan ketidaklinieran pada sistem. Rotary inverter pendulumu adalah sistem non linear orde tinggi, multivariabel dan sistem dinamik yang sangat tidak stabil. Untuk mengatasi kekurangan pada kendali PID maka kendali PID digabungkan dengan kendali fuzzy yang diterapkan pada sistem rotary inverter pendulum. Pada penelitian ini yang menjadi fokus bahasan adalah analisis kendali hybrid PID-Fuzzy dalam menjaga keseimbangan pendulum sehingga dapat tetap seimbang pada posisi atas. Berdasarkan hasil pengujian dengan memberikan sudut awal 0.1 radian pada pendulum, kendali hybrid PID-Fuzzy dapat menjaga pendulum tetap berada pada posisi seimbang dengan settling time sebesar 0.7 detik dan kendali hybrid PID-Fuzzy dapat meredam gangguan pada detik ke 3 sampai detik ke 5 serta gangguan pada detik ke 6 sampai ke 8 dengan recovery time yang baik.

Abstract

Induction motor has a weakness in the speed settings, the speed will change when there is a change in load or control signal disturbance, it takes a controller that is able to overcome the shortcomings of the induction motor, one of the controller is fuzzy. Fuzzy controllers have the advantage of modeling a complex non-linear function. But fuzzy controllers have weaknesses in the form of overshoot and system oscillation. One of the controllers that is able to overcome the weakness of overshoot and oscillation of the system from the fuzzy controller is the Sliding Mode Control (SMC) controller. SMC has the advantage of being robust and able to work on non-linear system systems that have model or parameter uncertainty. Based on simulation results from fuzzy hybrid controller and SMC able to cover the weakness of fuzzy and robust controller in overcoming the load and disturbance changes. Proven with time response analysis on overshoot and steady state error better than fuzzy controller with longer transient time value at maximum load with steady state error 0,0085 Rpm with Maximum overshoot 0,38% and without system oscillation.

Abstract

Dalam dunia industri kimia, Coupled Tank sangat penting terutama untuk proses-proses pencampuran beberapa fluida. Coupled Tank merupakan tangki yang terdiri atas dua atau lebih tangki yang saling terhubung. Ada berbagai macam sistem pengendali diataranya Proportional Integral Derivative (PID), Sliding Mode Control (SMC), dan sebagainya. Pada tugas akhir ini membandingkan pengendali SMC, PID, dan SMC hybrid PID pada sistem level Coupled Tank. Simulasi dilakukan dengan parameter yang sama. Untuk nilai parameter PID digunakan nilai Kp= 10000, Ki= 0.1, Kd= 0.1 sedangkan SMC digunakan konstanta K=80 dan =0,15. Penggunaan parameter yang sama membuat hasil simulasi pengendali SMC hybrid PID tidak mampu mendapatkan nilai set point yang diinginkan.. Namun penggunaan nilai parameter yang berbeda mampu memberikan nilai respon transien yang lebih cepat dibandingkan pengendali PID dan SMC, dengan menggunakan nilai parameter Kp= 3, Ki= 0.1, Kd= 0.1, dan parameter K=320 dan =0,05. Kata Kunci: Coupled Tank, Level, Proportional Integral Derivative (PID), Sliding Mode Control (SMC)

Abstract

Seaweed cultivation activities in Jeneponto Regency have been practised for a long time and have become the main livelihood for most of the Mallasoro Bay community. In cultivating seaweed, obstacles often arise in the form of failures experienced by seaweed farmers or poor-quality yields. This study was aimed to develop alternative planting calendars for Eucheuma sp. in Mallasoro Bay, Jeneponto Regency based on sea surface temperature and distribution of chlorophyll-a obtained from Landsat-8 imagery. Image Processing Sea Surface Temperature and Chlorophyll-a were processed using ENVI 4.8 AND 5.3 software, the satellite images used were clean and without cloud disturbance. In this study, data analysis was carried out descriptively. The water temperature that is good for seaweed growth is 27-30˚C, for Mallasoro Bay Sea Surface Temperature which is suitable for seaweed cultivation, namely April, May, June, July, August, September, October and November. While the classification is based on the criteria for chlorophyll-a trophic status in marine waters, namely the range < 1 mg/L is classified as Oligotrophic, ≥ 1–3 mg/L is classified as Mesotrophic, ≥ 3–5 mg/L is classified as Eutrophic, and > 5 mg/L is classified as Hypertrophic. , from the results of image analysis for the distribution of chlorophyll-a in Mallasoro Bay, it shows that Mallasoro Bay is at the Mesotrophic level throughout the year or the fertility level of the waters is quite fertile because it is in the range of ≥ 1–3 mg/L. so that a seaweed planting calendar can be obtained in Mallasoro Bay, namely in January, February and December, preparation of tools such as cleaning and repair of seaweed planting tools can be carried out, then at the end of March, the end of May, the end of July and the end of September, the procurement of seaweed seeds is carried out. , in early April, early June, early August, and early October, seaweed seeds can be spread, then in mid-May, mid-July, mid-September, and mid-November, harvesting can be carried out, so that seaweed cultivation can be carried out 4 times in one year. cycle.

Abstract

Abstract- Libraries generally provide lockers for users to store their luggage. Lockers in general still use conventional security by using manual locks. Currently, UIN Suska Riau Central Library still uses conventional key security which is considered easy to duplicate, lose, and damage. The purpose of this research is to improve locker security for user convenience and security through a system integrated with RFID, dual camera monitoring, and telegram notification. This tool has a CRUD (Create, Read, Update, Delete) system embedded in the telegram application managed by the admin. Admin can register, delete, and monitor locker user activities. This tool can identify registered and unregistered RFID tags properly. When a registered user accesses the locker, the system will send a picture of the user and a message to the telegram. Meanwhile, when an unregistered user accesses the locker 3 times incorrectly, the device will send the user's picture and message to the telegram and an alarm will sound for 3 seconds as an indication of an attempted locker break-in. The speed of information notification from the Internet of Things system has a delay in sending images with stability in the range of 3 - 4 seconds with relatively strong internet provider speed stability. Keywords— locker security, internet of things, RFID, dual camera monitoring, telegram

Abstract

Abstract—PT PLN Nusantara Power UP Tenayan is a steam power plant (PLTU) with a capacity of 2 x 110 MW which is a buffer for the electricity system in the Central Sumatra section. In the production process of PT PLN Nusantara Power UP Tenayan it does not always go well,. So that it will have an impact on the production stages of the power plant. One of the production machines that often fails and disrupts the production stage is the steam condenser. This research uses the Failure Mode And Effect Analysis Method which aims to identify the type of failure, cause of failure, effect of failure, and determine the RPN value. The research phase begins with data collection from literature studies, interviews, field observations, data analysis, FMEA analysis, results and discussion, conclusions. Based on the results of the RPN calculation, each component of the steam condenser instrumentation does not exceed the RPN standard limit of less than 200, although the temperature indicator has the highest RPN value but is still categorized as reliable and not recommended for immediate maintenance action. The results of identifying the type of failure are that there are inaccurate indications, there are switches with sticky conditions, there are displays that are unclear or blurry, and there is a mismatch between the data displayed in the DCS and the data displayed in the local area. For recommended actions on the steam condenser instrumentation components, among others, carry out more incentive maintenance every 3 months, make improvements to the specifications of the switch according to the amount of pressure to be measured, move the sensor to a safer area and protected from water exposure, carry out a zero calibration process on the steam condenser instrumentation components every six months.
