Abstract

Customer satisfaction is a crucial indicator in assessing the quality of a company's products, services and overall experience. This research aims to identify the level of customer satisfaction and optimize the available data for effective use in sentiment analysis. In this study, we analyzed 4,353 customer reviews collected over the past year, with 3,481 reviews used as training data and 871 reviews as testing data. The analysis process was conducted using the Cross-Industry Standard Process for Data Mining (CRISP-DM) approach and leveraged the Logistic Regression algorithm to build a predictive model. Model evaluation using the confusion matrix yielded an accuracy of 94.60%, a precision of 94.26%, and a recall of 94.60%. The analysis was conducted using Jupyter Notebook and the Python programming language. The results indicate that sentiment analysis is effective in identifying and predicting customer satisfaction levels, which in turn can help a company’s products improve its service strategies. The optimization of previously underutilized data now provides deeper insights into customer perceptions and expectations, enabling the company to make more targeted decisions and enhance overall customer satisfaction.

Abstract

Lemahnya sinyal wireless yang digunakan sebagai link transmisi gelombang radio akan menyebabkan kinerja yang kurang baik pada perangkat pendukung komunikasi jaringan internet. Kondisi ini sering terjadi pada daerah daerah tertentu dimana lokasinya berada jauh dari jangkauan sinyal yag dipancarkan oleh BTS. Jika hasil pengukuran kekuatan sinyal transmisi wireless berada diantara -100dBm s/d -9,0dBm maka sinyal transmisi dikategorikan pada kondisi yang lemah, sehingga kemungkinan terjadinya error dalam transmisi data menjadi tinggi. Sedangkan sinyal yang memiliki kekuatan diatas -80dBm dapat dikategorikan sebagai sinyal transmisi yang kuat. Maka untuk meningkatkan kualitas sinyal transmisi wireless dapat diwujudkan dengan melakukan rancang bangun perangkat berupa prototipe Antena-Grid yang mampu memfokuskan kekuatan sinyal transmisi pada suatu titik fokus sehingga sinyal yang dikumpulkan pada titik fokus antena mengalami pengingkatan gain, sehingga kapasitas data yang dapat disalurkan mengalami peningkatan , baik pada arah uplink maupun arah downlink. Pengukuran dilakukan dengan 2 Aplikasi berbasis wireless , yaitu Network Cell Info dan Open signal , masing masing percobaan dilakukan selama 5 hari untuk mendapatkan data pengukuran kekuatan sinyal yang terbaik , Hasil yang diperoleh adalah adanya peningkatan dalam dalam kekuatan sinyal trasmisi yang diperoleh berada dalam range -80dBm sampai -70dBm, yang merupakan sinyal yang dapat dikategorikan kuat. Selain itu kecepatan transfer data berada dalam range 2,8 Mbps sampai 4,8 Mbps, yang merupakan kecepatan yang cukup baik jika digunakan untuk mentransmisikan data internet.

Abstract

Irrigation is one of the important factors in the agricultural and plantation industries. In addition, irrigation is also important for watering city parks and urban forests. Irrigation is needed to maintain water availability. Based on this, proper water management efforts are needed, especially for irrigation that is carried out conventionally because it is inefficient so that it requires a lot of water that does not match the needs. Conventional irrigation also takes a lot of time just to irrigate plants so that it is less effective for large and relatively large areas. For this reason, technology is needed that automatically carries out irrigation effectively and efficiently. This community service aims to be implemented in the Pondok Labu city forest which currently requires automatic watering to make it easier to carry out irrigation which can later be monitored. The system used in this study is automatic irrigation based on the Internet of Things (IoT). Automation uses Arduino Mega Pro Mini and other supporting components. Watering can be done automatically according to schedule or if the soil conditions are dry and stop watering on soil that shows moisture. Automatic irrigation can also be monitored using a smartphone by utilizing a smartphone application.

Abstract

Barrel temperature stability is a crucial factor in the polymer extrusion process, as temperature fluctuations directly affect melt viscosity and final product quality. This study designed a temperature control system for a single-screw extruder using an ESP32 microcontroller to compare the performance of the Proportional-Integral-Derivative (PID) method against a system without control (open loop). The research methodology involved testing various screw rotation speeds from 50 to 200 RPM to observe barrel temperature stability and melt homogeneity. The determination of the PID parameters in this study was based on the evaluation of the open-loop system's thermal response mapping, yielding optimal tuning values of Kp = 4.8, Ki = 0.09, and Kd = 55. The test results showed that the system without control experienced temperature fluctuations of ±8–12°C, while the PID controller successfully maintained temperature stability with a low deviation of ±1–3°C. Furthermore, the PID system was able to automatically compensate for temperature increases caused by material friction at high speeds. The implementation of PID control was proven to increase thermal stability by up to 80% compared to conventional systems. These results demonstrate that the use of PID algorithms on microcontrollers ensures a more precise and stable plastic extrusion process compared to traditional methods.
