Abstract

Electricity plays a crucial role in the operations of companies and offices, as highlighted in the 2022 data from the Ministry of Energy and Mineral Resources. The commercial sector recorded an energy usage of 49.65 million BOE (Barrel Oil Equivalent) and 68.891 GWh of electricity consumption. Excessive use of electrical equipment leads to wastage, resulting in higher electricity bills. Thus, there is a need for an efficient system in both lighting and other areas, with efforts focused on enhancing energy efficiency through conservation.This Final Project aims to determine and analyze Energy Consumption Intensity (IKE) values, lighting systems, and identify opportunities for electricity consumption savings at the PT. X Lampung Office Building. The research method involves an initial energy audit and brief measurements on the lighting system. Results indicate that, out of 13 rooms on all three floors, only 5 meet the standards. The analysis identifies opportunities for electricity consumption savings, with a no-cost method at 8.1% and a low-cost method at 9.1%. These findings are expected to serve as recommendations for identifying energy-saving opportunities in Indonesian office buildings.

Abstract

Proses pengeringan merupakan hal penting dalam penanganan bahan pertanian pasca panen, akan tetapi proses pengeringan yang dilakukan para petani di Gorontalo khususnya di Gororontalo Utara masih menggunakan metode pengeringan manual yang masih bergantung pada intensitas cahaya matahari dan masih membutuhkan waktu yang lama untuk proses pengeringannya. Hal ini yang membuat peneliti megambil inisiatif untuk merancang model alat pengering indoor otomatis hasil pertanian berbasis arduino uno yang bertujuan untuk mempercepat proses pengeringan dan tidak bergantung pada intensitas cahaya matahari. Metode yang digunakan dalam penelitian ini adalah metode eksperimen dimana peneliti membuat model alat pengering otomatis dan melakukan percobaan menggunakan jagung, gabah dan kedelai terhadap kerja alat yang dibuat. Alat ini bekerja di kontrol langsung oleh arduino yang menerima sinyal dari sensor DHT11 sebagai moniroring suhu dan soil moisture sensor sebagai monitoring kadar air yang terkandung pada bahan hasil pertanian.  Alat ini dapat mengeringkan bahan pertanian biji-bijian 2 sampai 3 jam tergantung jumlah kadar air yang terkandung dalam produk bahan pertanian. Hasil penelitian menunjukan bahwa alat yang dibuat sudah berhasil dan sudah bekerja sesuai dengan perancangan yang direncanakan.The drying process is important in handling post-harvest agricultural materials, however the drying process carried out by farmers in Gorontalo, especially in North Gororntalo, still uses manual drying methods which still depend on the intensity of sunlight and still require a long time for the drying process. This is what made researchers take the initiative to design a model of an automatic indoor dryer for agricultural products based on Arduino Uno which aims to speed up the drying process and does not depend on the intensity of sunlight. The method used in this research is an experimental method where the researcher makes a model of an automatic drying tool and carries out experiments using corn, grain and soybeans on the working of the tool made. This tool works under direct control by Arduino which receives signals from the DHT11 sensor for temperature monitoring and the soil moisture sensor for monitoring the water content contained in agricultural produce. This tool can dry grain agricultural materials for 2 to 3 hours depending on the amount of water content contained in the agricultural product. The research results show that the tool created has been successful and has worked according to the planned design.

Abstract

Parkir merupakan kegiatan yang selalu kita lakukan dan wajib bagi kita yang memiliki kendaraan apalagi kendaraan roda empat untuk dalam memakirkan kendaraan dibutuhkan kepresisian, terutama adalah tidak menabrak sesuatu. Nah ini merupakan menjadi tantangan tersendiri bagi supir mobil terlebih mobil yang besar tentunya memiliki blind-spot atau titik buta yang lebih tinggi. Kadang setiap orang yang ingin memakirkan kendaraan tersebut harus menengok ke kaca spion walaupun,memiliki kaca spion tetap saja kita tidak bisa mengetahui jarak yang pasti antara objek dibelakang dan mobil dan kadang kita pun berbalik ke belakang untuk mengetahui apakah ada objek di belakang atau tidak tentu ini dapat menjadi masalah yang cukup serius dikarenakan dapa membahayakan orang di sekitar ataupun merugikan kita sendiri jika terjadi tabrakan yang mana terjadi dikarenakan blind-spot. Dalam masalah tersebut kami membuat prototipe, “Rancang Bangun Sistem Sensor Parkir Kendaraan Roda Empat Berbasis Mikrokontroler” Sistem Sensor Parkir ini merupakan sistem yang digunakan untuk mendeteksi objek di belakang dengan memanfaatkan sensor HC-SR04, dengan pengaturan jarak yang bisa diatur. Bila sensor mendeteksi ada benda di belakang kendaraan ada lampu indikator (Led) yang menyala dan alarm / buzzer yang ada berbunyi, kemudian dari bunyi peringatan ini pengemudi dapat mengetahui dan sadar bahwa kendaraannya dekat dan hampir menabrak objek yang ada di belakangnya dengan adanya sensor parkir ini dapat meminimalisir terjadi tabrakan bagi orang, objek, dan lain-lain. Metode yang digunakan yaitu prototipe pengembangan. Hasil pengujian sistem menunjukkan bahwa sistem sensor parkir ini berfungsi dan memiliki akurasi yang baik dalam mendeteksi objek dan meningkatkan efisiensi pengendara dalam memarkirkan mobilnya.Parking is an activity that we frequently engage in and is mandatory for those of us who own vehicles, especially four-wheeled ones. Precision is required when parking, particularly to avoid collisions. This becomes a significant challenge, especially for drivers of larger vehicles that may have higher blind spots. Often, individuals who wish to park their vehicles must check their rearview mirrors. However, even with rearview mirrors, it's challenging to ascertain the precise distance between objects behind the vehicle. At times, we need to turn around to determine whether there are objects behind us, which can be a serious issue as it may endanger people in the vicinity or result in accidents due to blind spots.To address this issue, we have developed a prototype titled "Design and Construction of a Four-Wheeled Vehicle Parking Sensor Sistem Based on Microcontroller." The Parking Sensor Sistem is designed to detect objects behind the vehicle using an HC-SR04 sensor with adjustable distance settings. When the sensor detects an object behind the vehicle, indicator lights (LEDs) illuminate, and an alarm/buzzer sounds. Through this warning signal, the driver becomes aware that their vehicle is approaching and is close to colliding with an object behind it. The parking sensor sistem helps minimize the risk of collisions with people, objects, and other obstacles. The methodology used for development is a prototype. The results of the sistem testing demonstrate that the parking sensor sistem functions effectively and provides good accuracy in detecting objects, thereby enhancing driver efficiency in parking their vehicles.

Abstract

An inverter is an electrical device that converts direct current (DC) into alternating current (AC). Typically, a standard inverter operates at three voltage levels: +Vdc, -Vdc, and 0. However, a multilevel inverter consists of several smaller inverters connected in a series to produce multiple voltage levels at the output. The primary advantage of this type of inverter lies in its ability to produce a much lower harmonic distortion compared to traditional, non-multilevel inverters. Additionally, the switching components of a multilevel inverter operate at lower frequencies, which makes it more suitable for highpower applications. This research focuses on a threephase cascaded multilevel inverter, specifically generating output waveforms with up to seven levels. The study involves conducting experiments using RL loads, to observe how these variations affect the output waveforms and their harmonic distortions. The result, THDi values are much lower, with the 3rd harmonic contributing 0.02%, the 5th contributing 0.006%, the 7th contributing 0.004%, the 9th contributing 0.002%, the 11th contributing 0.002%, and the 13th harmonic contributing just 0.001%. These results suggest that the voltage harmonic more significant harmonic distortion than the current, particularly at the 13th harmonic order. This increase highlights the effect of inductive loads on the performance of the inverter, particularly in terms of harmonic content. These findings are crucial for optimizing multilevel inverters in practical applications, ensuring improved performance and efficiency.

Abstract

Quality measurement consists of three stages: data collection, data testing, and data processing. In general, each of these stages requires a significant amount of time. The process starts with the data collection stage, which may involve questionnaires. Distributing, completing, and collecting questionnaires will take a considerable amount of time. Similarly, the second stage, data testing, is carried out to validate whether the data obtained in the previous stage is accurate or not. The third stage will only take place once the data from the first two stages is deemed valid. Data processing itself also requires a significant amount of time because the data must be entered individually. Based on this issue, a system is needed that can integrate all three stages to expedite the overall process. The objective of this research is to design a web-based service quality measurement application that can integrate all three stages simultaneously. The data processing stage in this research uses the Service Quality method, also known as the SERVQUAL method. The application design is carried out using the Systems Development Life Cycle (SDLC) development method with the prototype model. Application testing is conducted using three stages: alpha testing, beta testing, and usability testing. Alpha testing refers to internal testing of the application. Beta testing, using the black-box method, resulted in a score of 83.33%. Usability testing, using the System Usability Scale (SUS), obtained a score of 81, which falls within the Acceptability Range. In the Adjective Range category, the application was rated as excellent, and on the grade scale, it was rated as B.Pengukuran kualitas memiliki 3 tahapan, yakni pengumpulan data, pengujian data, dan pengolahan data. Secara umum, setiap tahapan ini dilalui dengan durasi waktu yang lama. Berawal dari tahapan pengumpulan data misalnya dengan kuesioner. Penyebaran, pengisian maupun pengumpulan kuesioner akan memerlukan waktu yang tidak singkat. Demikian pula, menuju ke tapanan yang kedua yaitu pengujian data, dimana tahapan ini dilakukan untuk menguji apakah data yang diperoleh pada tahapan sebelumnya valid atau tidak.  Tahapan ketiga akan dilakukan jika data yang diperoleh pada dua tahapan sebelumnya sudah valid. Proses pengolahan data pun akan memerlukan waktu yang cukup lama karena datanya akan dimasukan satu per satu. Berdasarkan permasalahan ini maka diperlukan sebuah sistem yang dapat mengintegrasikan ketiga tahapan tersebut untuk mempercepat keseluruhan proses. Tujuan penelitian ini adalah merancang sebuah aplikasi pengukuran kualitas layanan berbasis web yang dapat mengintegrasikan ketiga tahapan ini sekaligus. Tahapan pengolahan data pada penelitian ini menggunakan metode Service Quality atau lebih dikenal dengan metode SERVQUAL. Perancangan aplikasi dilakukan menggunakan metode pengembangan Systems Development Life Cycle (SDLC) dengan model prototype. Pengujian aplikasi dilakukan menggunakan tiga tahapan, yaitu alpha testing, beta testing, dan tes usabilitas. Alpha testing yaitu pengujian aplikasi secara internal. Beta testing menggunakan metode blackbox mendapatkan hasil sebesar 83,33%. Pengujian tes usabilitas menggunakan System Usability Scale (SUS) dan mendapatkan skor 81, yang masuk pada tingkat Acceptability Range. Pada kategori Adjective Range, aplikasi dinilai berada pada tingkatan excellent, dan pada grade scale berada pada tingkatan B.

Abstract

Nila merupakan ikan air tawar yang banyak dibudidayakan karena memiliki beberapa kelebihan dibanding jenis ikan lainnya, ikan ini unggul dalam pertumbuhan cepat, kemudahan berkembang biak, serta kemampuan adaptasi yang baik terhadap lingkungan. Meskipun demikian, budidaya ikan ini tidak lepas dari ancaman hama yang dapat mengganggu, khususnya predator biawak yang dapat menghancurkan populasi ikan dalam kolam dengan cepat. Kemajuan perkembangan teknologi IoT dapat dimanfaatkan dalam pembuatan prototipe perangkap otomatis dengan notifikasi berbasis smartphone. Dengan demikian, pemilik kolam dapat mengetahui jika biawak telah berhasil terperangkap tanpa harus berada di area kolam sepanjang waktu. Penelitian ini menggunakan metode eksperimen, metode ini melibatkan pengamatan dari suatu eksperimen dengan membuat suatu alat serta melakukan uji coba prototipe yang telah selesai dibuat. Alat ini menggunakan sensor PIR sebagai masukan yang akan diproses oleh mikrokontroller ESP32 dengan keluaran berupa pintu otomatis dan notifikasi aplikasi Blynk pada smartphone secara bersamaan. Hasil pengujian pertama menunjukkan penggunaan ESP32 dengan koneksi hotspot mendapatkan perolehan waktu rata-rata 0.76 detik yang dapat dikatakan sangat responsif. Sedangkan untuk pengujian kedua, yaitu  kecepatan reaksi setelah sensor berhasil mendeteksi objek hingga pintu tertutup secara otomatis memperoleh waktu rata-rata 2.33 detik yang tergolong cukup baik meskipun masih ada jeda waktu. Pada pengujian ketiga, perangkap ini berhasil menjebak biawak pada hari ke-3. Meskipun masih terdapat beberapa kekurangan, penelitian ini sangat bermanfaat bagi pembudidaya ikan, terutama pada kolam tanah karena perangkap ini membantu pemilik kolam mengatasi potensi kerugian akibat biawak yang kerap memangsa ikan  hasil budidaya. Selain itu, pemilik kolam juga mendapat penghasilan tambahan dari hasil menjual biawak hidup dibanding menjual biawak mati.Tilapia is a freshwater fish that is widely cultivated because it has several advantages over other types of fish, this fish excels in fast growth, ease of breeding, and good adaptability to the environment. However, this fish farming is not free from the threat of pests that can interfere, especially predatory lizards that can destroy fish populations in ponds quickly. The advancement of IoT technology development can be utilized in making automatic trap prototypes with smartphone-based notifications. Thus, the pond owner can know if the monitor lizard has been successfully trapped without having to be in the pond area all the time. This research uses the experimental method, this method involves observing an experiment by making a tool and testing the prototype that has been completed. This tool uses a PIR sensor as input that will be processed by the ESP32 microcontroller with the output in the form of an automatic door and notification of the Blynk application on the smartphone simultaneously. The first test results show the use of ESP32 with a hotspot connection getting an average time of 0.76 seconds which can be said to be very responsive. As for the second test, which is the speed of reaction after the sensor successfully detects the object until the door is automatically closed, the average time is 2.33 seconds which is quite good even though there is still a delay. In the third test, this trap successfully trapped monitor lizards on the 3rd day. Although there are still some shortcomings, this research is very useful for fish farmers, especially in earthen ponds because this trap helps pond owners overcome potential losses due to lizards that often prey on cultured fish. In addition, the pond owner also gets additional income from selling live monitor lizards instead of selling dead lizards.
