Abstract

Pada era saat ini hampir semua kegiatan tidak terkecuali bidang pendidikan sudah menerapkan penggunaan teknologi dalam menjalankan kegiatan pembelajaran. Yayasan Islam Nurus Sunnah yang terletak di Kelurahan Bulusan Kecamatan Tembalang Kota Semarang belum menerapkan teknologi informasi untuk sistem penilaian guru. Permasalah utama yang ada Yayasan Nurus Sunnah ini adalah melakukan penilaian guru mitra masih dilakukan secara manual sehingga mengalami beberapa kendala. Kendala yang dihadapi yaitu data yang tidak terintegrasi, kurangnya aksesibilitas terhadap data, proses penilaian yang tidak fleksibel dan keamanan data yang kurang terjamin. Alternatif solusi yang akan diterapkan pada mitra tersebut adalah menyediakan sistem online berbasis web untuk proses penilaian kinerja guru. Proses digitalisai penilaian guru diharapkan dapat mengintegrasikan data dan mempermudah proses penilaian guru. Kegiatan ini terdiri dari empat tahapan, tahapan pertama adalah identifikasi kebutuhan untuk kegiatan observasi lapangan, diskusi dengan mitra, dan analisis situasi untuk menetapkan permasalahan yang dihadapi mitra. Tahapan  kedua adalah perencanan dilakukan dengan proses desain aplikasi dan database aplikasi online berbasis web serta pembuatan aplikasi web dan database. Tahapan ketiga digunakan untuk pelatihan SDM agar terampil dalam mengoperasikan sistem aplikasi berbasis web dan sekaligus dilakukan uji coba (trial and error) penerapan dan koreksi sistem aplikasi web. Tahapan keempat adalah evaluasi terkait kerja sistem. Impelementasi hasil kegiatan menunjukkan meningkatkan performansi kegiatan penilaian guru yang dilakukan setiap periode menjadi lebih cepat dan akurat. Mitra mendapatkan dampak positif dengan diterapkannya sistem digitalisasi sistem penilaian guru. Solusi ini yang diberikan terbukti bisa efektif untuk membantu dalam manajemen penilaian guru pada mitra.   Nowadays, almost all educational activities are conducted online unless the field of education has already adopted the use of technology in teaching. The Nurus Sunnah of Islam that is practiced in the Kelurahan Bulusan Kecamatan Tembalang Kota Semarang does not use information technology for its guru certification system. The primary problem with this Yayasan Nurus Sunnah is that the mitra penilaian is mostly done manually, resulting in a few kendals. The data that is being handled include incomplete data, inconsistent data accessibility, non-flexible data processing procedures, and inconsistent data quality. Offering these partners a web-based online system for the teacher performance assessment procedure is an alternate approach that will be used. It is anticipated that the digitization process for teacher assessments will facilitate data integration and streamline the process. There are four stages to this activity. The first is determining the need for field observation exercises, partner discussions, and situation analysis to ascertain the issues that partners are facing. The creation of web applications and databases, along with the application design process and web-based online application database, comprise the second stage of planning. In the third stage, HR personnel receive training on how to effectively operate web-based application systems and conduct trial-and-error procedures for the purpose of implementing and optimizing web application systems. The assessment of the system's functionality is the fourth step. The application of the activity results demonstrates that there has been an increase in the speed and accuracy of the teacher assessment tasks completed each period. Partners' implementation of the teacher assessment system's digitalization has produced positive results. It has been demonstrated that this solution works well to help partners manage teacher assessments.

Abstract

Vegetable farmers in Bebengan Village, Kendal Regency, still mostly water their crops manually, resulting in inefficient water usage and inconsistent watering timing. Additionally, the water quality for irrigation has not been monitored regularly, even though pH and PPM parameters affect nutrient availability and plant growth. This service activity aims to implement an Internet of Things (IoT)-based automatic plant watering technology that can monitor pH and PPM and provide easy control through Google Assistant. The implementation methods include observing partner needs, designing and assembling an Arduino ATmega 2560 and ESP8266-based system with pH and PPM sensors, installing it on a 200 m² cultivation area, integrating remote monitoring and control, and training farmers on operating and maintaining the equipment. Implementing the system allows for more scheduled/controlled watering and provides real-time pH and PPM information as a basis for decision-making. In conclusion, the implementation of this IoT system improves the effectiveness of the watering process, supports water quality monitoring, and simplifies operations through voice-based control, thus potentially increasing cultivation efficiency at the farmer level.

Abstract

This study compares the performance of Gain Scheduling Proportional–Integral–Derivative (GS-PID) control and Fuzzy Mamdani control applied to an air heating module. The system was implemented using an STM32 microcontroller and evaluated experimentally under temperature setpoints of 50 °C, 60 °C, 70 °C, and 80 °C. Performance was assessed based on dynamic response parameters, including rise time, overshoot, steady-state error (SSE), Integral of Absolute Error (IAE), Integral of Squared Error (ISE), and Integral of Time-weighted Absolute Error (ITAE). The experimental results show distinct characteristics between the Gain Scheduling PID (GS-PID) and Fuzzy Mamdani controllers under varying setpoints. The GS-PID controller exhibits a rise time of approximately 4.0–4.9 s with relatively small overshoot in the range of 1.18–2.87%, while maintaining a very low steady-state error of about 0.001–0.24%. In contrast, the Fuzzy Mamdani controller achieves a faster rise time of around 2.0–2.6 s at low to medium setpoints, which increases to approximately 5 s at higher temperatures. The overshoot produced by the Fuzzy Mamdani method ranges from 0–4.78%, decreasing as the setpoint increases, with zero overshoot observed at high setpoints due to incomplete setpoint tracking. Moreover, the Fuzzy Mamdani controller yields higher performance index values (IAE, ISE, and ITAE), indicating larger accumulated error over time. Overall, GS-PID control is more effective in ensuring steady-state accuracy and stability, whereas Fuzzy Mamdani control provides a faster transient response at lower operating temperatures.
