Abstract

Air merupakan sumber daya alam yang menjadi salah satu kebutuhan utama dalam kehidupan dan sampai saat ini belum ada senyawa lain yang dapat menggantikannya. Sulitnya mendapatkan air yang berkualitas saat ini masih menjadi problem di beberapa daerah. Masyarakat yang memanfaatkan sumur sebagai sumber kebutuhan air pun terkadang masih mengalami masalah pada kualitas air yang dihasilkan sumur tersebut. Air yang belum layak digunakan khususnya dikonsumsi harus diproses terlebih dahulu, misalnya proses filtrasi. Penelitian ini merancang bangun sebuah sistem penjernih air menggunakan sistem filtrasi yang dapat secara otomatis memfiltrasi secara berulang jika air hasil filtrasi masih melebihi batas nilai kekeruhannya. Sistem filtrasi menggunakan bahan pipa PVC sebagai tabung reaktor filtrasinya dan beberapa bahan penjernihnya yaitu karbon aktif, pasir manganese dan kapas. Sistem penjernih dilengkapi dengan sistem monitoring yang dapat menampilkan nilai kekeruhan air melalui aplikasi Blynk. Beberapa perangkat elektronik yang digunakan yaitu esp32 sebagai kontroler, sensor turbidity untuk mengukur kekeruhan air, sensor ultrasonik untuk mengukur level air pada bak penampung serta pompa DC untuk mengalirkan air dari bak penampung ke reaktor filtrasi. Berdasarkan pengujian sistem filtrasi, menunjukkan bahwa sistem penjernih dapat menjernihkan air dengan tingkat penjernihan sampai dengan 47,56 %. Status air yang diproses filtrasi dapat dimonitoring melalui aplikasi Blynk sesuai dengan perancangan. Informasi bak penampungan air dan nilai kekeruhan air dapat ditampilkan pada aplikasi Blynk dengan baik. Selain itu, pompa air yang terdapat sistem penjernih dapat dikontrol secara manual melalui aplikasi Blynk yang digunakan.

Abstract

Hydroponic system is a technique of cultivating plants without using soil as a growing medium, but using water that is given nutrients and oxygen as a growing medium. Cultivation with hydroponic techniques must be able to pay attention and control nutrients, water content, and water ph. This research aims to create a lettuce cultivation system with intelligent hydroponic techniques using the ATmega2560 microcontroller. This system uses Arduino Mega as the control center, TDS sensor to monitor nutrition, PH sensor to monitor water acidity, and ultrasonic sensor to monitor water level. The optimal growth characteristic of lettuce is that the acidity level must be at pH 5.5-6.5 with the nutrients provided at 685-950 ppm. This system can help lettuce cultivation with hydroponic techniques by monitoring and controlling nutrients, pH, and water content in cultivated plants in real time to optimize lettuce growth.

Abstract

  Abstract— Masalah sampah merupakan masalah yang cukup berpotensi menyebabkan dampak buruk bagi lingkungan di perkotaan maupun di pedesaan. Penumpukan sampah berpotensi terhadap adanya banjir yaitu penumpukan sampah pada saluran air ataupun di sungai. Pada mayoritas masyarakat perkotaan, sampah secara illegal dibuang pada badan sungai atau pun sengaja ditunpuk pada bantaran sungai. Hal tersebut akan menyebabkan pencemaran pada air sungai dan mengurangi ketinggian irigasi sungai. Berdasarkan data dari Kementerian Lingkungan Hidup dan Kehutanan tercatat sampah nasional mencapai 67,8 juta ton per tahun 2020. Hal tersebut berarti sampah penduduk Indonesia mencapai 185.753 ton per hari. Perancangan prototipe alat konveyor pembersih sampah pada air sungai didesain dengan notifikasi SMS berbasis arduino uno. Alat ini dilengkapi dengan pengaturan sudut atau tinggi ujung konveyor yang digunakan untuk mengambil sampah berdasarkan ketinggian air sungai. Mekanisme pengaturan sudut konveyor menggunakan sebuah motor stepper. Notifikasi SMS ke nomer tujuan berisi informasi status bak penampungan sampah yang telah penuh menggunakan modul SIM800L. Pengangkatan sampah jenis kotak karton dan kayu, diketahui memiliki rata-rata tingkat keberhasilan sebesar 66% untuk jenis sampah kotak karton dan 76% untuk sampah jenis kayu. Terdapat perbedaan tingkat keberhasilan konveyor dalam mengangkat sampah, jenis sampah kotak karton memiliki keberhasilan pembersihan lebih rendah tingkat dibanding dengan jenis sampah kayu. Pengangkutan sampah mendapatkan rata-rata durasi waktu pengangkatan sampah sebesar 17,4 detik. Lama durasi ini dipengaruhi oleh proses pengangkatan sampah oleh konveyor 1 yang lebih banyak memakan waktu, dikarenakan antara sampah dengan bel konveyor cukup licin sehingga sampah terkadang cukup sulit untuk dapat terangkat.

Abstract

Banjarwaru Village is located in Nusa Wungu District and has several hamlets connected to the main road as access to transportation facilities. The lack of street lighting hampers the activities of village residents, especially at night. Road points that do not have public street lighting are far from residents' homes, so they cannot use PLN electricity sources. Seeing the conditions explained above, the need for technology with energy sources that utilize renewable energy such as solar power to supply power to public street lights has been widely implemented. Making street lights with a solar power supply with the application of modern technology is the main priority in this community service activity. The main target objective of this Community Service is the Public Street Lighting Program through the manufacture of street lights with power supply from solar energy. The implementation method in this service is through observation and experiments in the field in the process of designing and manufacturing public street lights and handing over technology transfer to the community. The results of making public street lights with solar energy supply using Arduino Mega which functions to receive data from the LDR sensor and is continued with testing battery charging with solar power. The installation of the LDR sensor will help the efficiency of the lights because it will control the lights to turn on automatically. The results of the manufacture of public street lights also provided assistance and training to the Banjarwaru Village community regarding how the equipment works and the repair process if problems arise in the future.

Abstract

Before coffee products are marketed, packaging is generally carried out first. Apart from protecting against damage, the packaging also aims to make it easier to carry while traveling. The conventional packaging process is quite time and energy consuming. This results in the packaging process being less efficient. With an automatic packaging system, it is hoped that it will make things easier and save time and energy. Automatic coffee bean packaging tools are built using several electronic devices. Arduino Uno is used as a controller, a load cell sensor to weigh the coffee packaging, a DS18B20 temperature sensor to measure the temperature of the packaging sealer and a proximity sensor to detect plastic packaging. In the actuator section, a servo motor is used to open the coffee bean reservoir valve (hopper tank), a DC motor is used to pull the packaging plastic and a stepper motor is used to press the packaging plastic. The plastic press is equipped with a heating mechanism using nickel wire so that the two layers of plastic can stick together. An LCD module is used to display information on the weight value of the coffee packaging, the temperature value of the sealer and the status of the packaging process. From the test results, it is known that the coffee bean packaging tool is capable of packaging coffee beans automatically. Coffee beans can be packaged in plastic with the weight and length of the packaging according to the design with a success rate of up to 87.5%

Abstract

Indonesia merupakan negara dengan iklim tropis. Salah satu musim di Indonesia adalah musim hujan. Curah hujan yang sangat tinggi dapat menimbulkan bencana banjir di berbagai wilayah Indonesia yang menimbulkan kerugian akhir maupun korban jiwa. Sistem peringatan dini bencana banjir menjadi salah satu solusi agar masyarakat Indonesia dapat mempersiapkan diri sejak dini ketika terjadi bencana. Penelitian sebelumnya telah membuat sistem bencana banjir dengan menggunakan GSM 900, namun permasalahannya ada beberapa lokasi penempatan sistem bencana banjir yang kurang sinyal GSM atau tidak ada sinyal GSM sama sekali. ,. Nilai RSSI terkecil yang diperoleh sebesar -87 dBm dan nilai tertinggi sebesar -128 dBm. Sedangkan pada jarak Non Line of Sight, Lora hanya mampu menjangkau jarak 520 meter dengan nilai RSSI terkecil - 128 dan nilai RSSI terbesar yaitu -147 dBm. Hal ini membuktikan bahwa dibutuhkan banyak node saat menggunakan Lora karena Lora memiliki keterbatasan jarak untuk komunikasi transmisi data

Abstract

The widespread use of smartphones in public places has driven the adoption of power banks as a solution for power needs. However, power banks have several drawbacks. To address these needs in public places, charger station systems have been widely implemented, including solar panel-based charger stations as their power source. These developments have also extended to commercial applications, allowing the use of charger station facilities in public places to be subject to specific charges. In this study, a solar charger station system with coin-operated payment for electricity was developed. Additionally, for system security, a feature was added to limit the current flow to the load to a specific amount. The charger station was built using several components, including solar panels, solar charge controllers, and batteries, which are integrated to produce electricity. An inverter is used to convert DC current into AC current, which is then connected to electrical terminals via a solid-state relay switch. Arduino Uno is used to control the electrical connection from the inverter to the terminal through the solid-state relay based on data from the coin acceptor and the PZEM-004T sensor. An LCD is also used to display information required by the users. The test results showed that the solar charger station system could successfully charge smartphones using 1,000-rupiah coins with a 100% success rate. With a rate of 1,000 rupiahs per 40Wh, the charger station system can disconnect the power supply to each load after consuming 40Wh of electricity. Additionally, the system is capable of disconnecting the load when the attached load exceeds 40W.

Abstract

This study developed a predictive model based on Random Forest algorithm to predict survival rate of Vannamei shrimp using five water quality parameters: dissolved oxygen (DO), temperature, pH, salinity, and Total Dissolved Solids (TDS). The model was trained on this data and evaluated using Mean Squared Error (MSE) and R² Score, with an MSE of 0.71 and R² Score of 1.00. Endpoint testing was conducted using Postman to verify the model response, with output parameters including anomaly_detected, recommendation, and survival rate. The model successfully detected anomalous conditions and provided recommendations according to the detected water quality parameters. Test results showed that DO and salinity had the greatest influence on survival rate, while pH, TDS, and temperature made moderate contributions.

Abstract

The majority of the population of Banjarwaru Village are farmers. The price of fertilizer is getting higher from time to time while farmers need fertilizer for their plants. Problems arise when fertilizer shortages often occur. In addition, the type of fertilizer used is generally a type of chemical fertilizer that is not good for the human body because the substance can be carried into the food consumed. Organic fertilizer is one option to overcome this problem. This type of fertilizer is now starting to be widely available on the market, although the price is relatively expensive. The solution to this problem is that it can be done by making organic fertilizer independently. Another factor is that there is a lot of organic waste that can be processed into liquid organic fertilizer (POC). Therefore, to create a village that is independent in fertilizer, the PKM Team aims to create an organic fertilizer maker based on a PLTS electricity source and provide training in operating the tool. The method used is by making an organic liquid fertilizer maker, socializing it to residents of Banjarwaru Village, and training and demonstrating how to operate the tool.
