RANCANG BANGUN SISTEM PAKAR UNTUK MENDIAGNOSA PENYAKIT PADA KULIT DENGAN METODE FOWARD CHAINING
Get PDFThis study aims to develop an artificial intelligence-based expert system to help diagnose skin diseases. This system is designed to help users, especially the general public, identify the type of skin disease based on the symptoms they experience. By collecting data from dermatologists and medical literature, this system is built using the forward chaining method. The system's knowledge base contains rules that link symptoms to certain skin diseases. System testing shows high accuracy in diagnosing various types of skin diseases, such as psoriasis, eczema, and fungal infections. With this expert system, it is expected to increase public access to skin health information and help early detection of skin diseases
PENGEMBANGAN APLIKASI GAME IQRO’ SEBAGAI MEDIA EDUKASI PADA ANAK MENGGUNAKAN CONSTRUCT 2
Get PDFLearning to read the Qur’an is a fundamental component of early Islamic education, with the Iqro’ method being one of the most widely used approaches in Indonesia. However, traditional implementations often lack interactivity and engagement, which can reduce their appeal to young learners. In response to this challenge and the increasing digital exposure among children, this study aims to develop an educational game application using Construct 2 as a supplementary medium for teaching Iqro’ reading skills to first-grade students at SD IT Al-Jauharotunnaqiyah Ciajeng. The application presents material from Iqro’ Volume 1 in an interactive format, incorporating audio pronunciation, multiple-choice quizzes, writing simulations, and immediate visual and auditory feedback. The implementation results indicate that the application fulfills both functional and non-functional requirements. Furthermore, black-box testing confirms that all features perform as intended. This application is considered a suitable and engaging tool to support early Qur’anic literacy and has the potential to redirect children’s screen time toward educational and spiritually enriching activities.Learning to read the Qur'an is a fundamental aspect of early Islamic education for children, with the Iqro’ method being one of the most widely adopted approaches in Indonesia.

Analisis Tingkat Kelelahan Pada Mahasiswa yang Bekerja di Batam
Get PDFThe phenomenon of students choosing to work while completing their studies has become increasingly common in recent years. The decision to work while studying often presents unique challenges for students. Fatigue resulting from academic and work pressures is a common risk faced by students who are employed. On the one hand, students must fulfill their academic obligations, such as assignments, exams, and projects, which require significant time and concentration. On the other hand, work demands additional time and energy, often involving heavy targets and responsibilities. The combination of academic and professional demands can lead to fatigue among students who are not working. In this context, analyzing fatigue among working students is crucial. This study was conducted on students at one of the universities in Batam. Fatigue was measured using the Fatigue Assessment Scale (FAS) questionnaire. The results of data processing and analysis showed that 2.57% of students were in the very low fatigue category, 9.65% experienced low fatigue, 27.33% experienced moderate fatigue, 47.27% experienced high fatigue, and 13.18% experienced very high fatigue. The results of the Chi-Square test showed that only the level of education had an effect on fatigue, while gender, age, and program of study did not have a significant relationship. The results of the ANOVA test showed that the fatigue experienced by students who were working and studying did not differ by gender and program of study, while for age groups and levels of education, the fatigue experienced by students differe
Studi Pengaruh Berbagai Metode Treatment Pada Karakteristik Tepung Rumput Laut Sargassum Sp.
Get PDFThis research aims to determine the effect of the Sargassum sp soaking method. using fresh water, salt water and distilled water to determine the characteristics of the flour produced. The analysis results showed that the highest flour yield was obtained by soaking using distilled water at 4.6%, followed by salt water at 4%, and fresh water at 3.73%. The highest protein content of flour was found in fresh water treatment at 30.6%, while the highest fat content was found in flour soaked in salt water reaching 20.59%, much higher than fresh water (5.03%) and distilled water (10.57%). The highest ash content was also observed in the saltwater treatment (32.57%). Soaking in fresh water produces the highest crude fiber content, namely 17.16%, followed by salt water 11.24% and distilled water 5.3%. The carbohydrate content in flour varies between 32.84% to 39.6%. This difference in composition is thought to be caused by variations in salinity and water chemical properties which affect the extraction of nutrients and fiber in seaweed. This research provides important insights in optimizing the Sargassum sp flour processing process. for food and feed industry applications, as well as the potential for maximum utilization of seaweed as an alternative nutritional source
