Abstract

Kehilangan orang tua memberikan dampak yang signifikan terhadap perkembangan psikologis remaja, yang mempengaruhi rasa diri dan problem traumatis tetapi banyak dari mereka yang bisa bangkit dan menunjukkan prestasti yang lebih baik. Tujuan dari penelitian ini adalah untuk mengetahui motivasi belajar pada remaja yang orangtuanya telah meninggal dunia. Penelitian ini menggunakan studi kasus dengan subjek sebanyak tiga orang yang memiliki karakterisik remaja hingga dewasa awal yang memiliki prestasi dan salah satu orangtuanya telah meninggal dunia, pengambilan sampel dilakukan dengan teknik purposive sampling. Pengumpulan data pada penelitian ini menggunakan wawancara semi terstruktur yang kemudian dianalisis menggunakan analisis tematik. Penelitian ini mengungkapkan bahwa remaja yang mengalami kematian orang tua mengalami kesedihan dan keadaan trauma yang buruk, kehilangan sosok orang yang dicintai yang menghilangkan dukungan sumber motivasi utama serta hilangnya kenyamanan. Menghadapi berbagai situasi masalah yang menyebabkan stress, dalam beberapa waktu membutuhkan kemampuan untuk mengelola permasalahan dan resiliensi yang mampu membuat mereka bertahan. Mereka juga memiliki sumber motivasi yang tinggi baik internal dan eksternal sehingga mampu memberikan prestasi yang terbaik

Abstract

Laptops are essential devices that support various academic activities for university students, such as writing assignments, programming, graphic design, and attending online classes. However, the wide range of available laptops with varying specifications and prices often makes it difficult for students to choose one that fits their needs and budget. This study aims to develop a Decision Support System (DSS) using the Simple Additive Weighting (SAW) method to assist students in selecting the most suitable laptop based on several relevant criteria. This research is a quantitative descriptive study. Data was collected using questionnaires and literature studies. The test results show that the system can accurately and efficiently generate laptop recommendations that align with user preferences. The conclusion of this study indicates that the application of the SAW method in a DSS is effective in simplifying the decision-making process for selecting laptops for academic purposes.

Abstract

Water baths are commonly used in scientific fields to incubate samples at specific temperatures. The temperature of the water bath must be controlled precisely, because even the slightest temperature variation can affect the results of the experiment. It can handle imprecise, uncertain and incomplete information, making it suitable for temperature control in water baths. This research aims to determine the distribution and stability of fuzzy logic control to control the temperature of a water bath with four heaters. Even heat distribution from the four heaters will ensure consistent water bath temperature throughout the bath. This research uses an Arduino microcontroller to process the temperature sensor output from the DS18B20, then the processed temperature value will be displayed on the TFT LCD. The independent variable in this research is the temperature value, while the dependent variable is the DS18B20 temperature sensor. The largest error value from the module measurements is at a temperature setting of 30 ºC on the 2nd temperature sensor with an error value of 1.43%. Meanwhile, the smallest error value is found at a temperature setting of 35 ºC on the 1st and 4th temperature sensors with an error value of 0.01%. Data collection used a digital thermometer comparison tool with 10 repetitions as a temperature sensor reference tool. The results obtained using this sensor are more stable and have a high accuracy value. The results of the research show that the temperature difference between points 1 to 4 when viewed from the error percentage is very small, or it can be said that the temperature distribution is even. The conclusion from these results is that the module has a stable temperature value and the error value is low and is still within the tolerance limit. permitted is ±5%.
