Abstract

Post-Traumatic Stress Disorder (PTSD) is a serious mental health condition that can develop after an individual experiences a traumatic event. Early diagnosis of PTSD symptoms is crucial to prevent more severe psychological and social impacts. This study aims to develop a mobile-based expert system application that implements the Dempster-Shafer method to independently diagnose the confidence level of PTSD symptoms. The system is designed with three main components: biodata input, a symptom selection interface based on 9 indicator questions, and an inference engine utilizing the Dempster-Shafer method with a Likert scale to assess the severity of trauma experienced by respondents. Testing was conducted on 47 respondents, and the analysis results showed that 19.1% were in the safe category, 4.3% in mild PTSD, 12.8% in moderate PTSD, and 63.8% in severe PTSD. Validity testing indicated that all symptom items had correlation values (r-calculated) greater than 0.2876, confirming their validity, and the instrument’s reliability was measured at α = 0.806. The application is capable of providing an initial diagnosis along with recommended actions based on the severity level of PTSD. This study demonstrates that applying the Dempster-Shafer method in a mobile application offers an effective, efficient, and accessible alternative solution for early PTSD diagnosis, especially for individuals with limited access to professional mental health services.

Abstract

Rice is the staple food source for the Indonesian nation. Quality rice is produced from superior rice seeds which have a high yield quantity. At present the agricultural sector is growing with many rice varieties emerging. Superior rice seeds are very important for farmers because rice seeds are the main factor that determine the success of rice cultivation. The existence of many choices makes farmers more careful in choosing the type of rice varieties that suit the soil structure and climatic conditions of the local agricultural environment. The Analytical Hierarchy Process (AHP) method is applied to determine the important criteria for rice varieties and to obtain alternatives that are in accordance with the environmental conditions of agricultural land. The alternatives used are the types of rice seeds in Indonesia, namely Inpari45, Baroma, Jeliteng, Pamelan, and Pamera. This Decision Support System was created to provide information and assist farmers in making decisions regarding the selection of rice seeds to be planted with the criteria of Upright Rice Height, Planting Age, Productive Saplings, and Yield Potential. By applying the AHP method to this Decision Support System, it is found that the best alternative has the highest value of 0.247.

Abstract

Gangguan kesehatan mental seperti depresi, kecemasan, dan stres merupakan permasalahan yang terus meningkat, khususnya pada kelompok usia produktif seperti mahasiswa. Deteksi dini gangguan mental masih menghadapi berbagai kendala, antara lain keterbatasan akses layanan profesional, stigma sosial, serta ketidakpastian gejala psikologis yang bersifat subjektif dan saling tumpang tindih. Penelitian ini bertujuan untuk mengembangkan model klasifikasi gangguan kesehatan mental berbasis sistem pakar menggunakan metode Dempster–Shafer dengan memanfaatkan evidence psikologis dari instrumen standar PHQ-9, GAD-7, dan DASS-21. Pendekatan yang digunakan adalah penelitian terapan dengan metode kuantitatif, di mana skor kuesioner dikonversi menjadi nilai belief dan dikombinasikan menggunakan teori Dempster–Shafer. Penelitian melibatkan 35 responden mahasiswa sebagai subjek penelitian. Hasil analisis menunjukkan bahwa metode Dempster–Shafer mampu menggabungkan evidence psikologis yang tidak pasti dan tumpang tindih untuk menghasilkan nilai keyakinan gangguan mental secara terukur. Hasil klasifikasi menunjukkan dominasi gangguan depresi dengan persentase 75,43% tingkat keyakinan tinggi dibandingkan gangguan kecemasan dan stres. Penelitian ini menyimpulkan bahwa integrasi instrumen psikologi standar dengan metode Dempster–Shafer efektif digunakan sebagai alat skrining dini gangguan kesehatan mental, namun tidak dimaksudkan sebagai pengganti diagnosis klinis.
