Penelitian ini meningkatkan teknik backward chaining untuk diagnosis Demam Berdarah Dengue (DBD) dengan mengintegrasikan algoritma backtracking, dengan tujuan untuk meningkatkan efisiensi penelusuran gejala dan aturan dalam sistem pakar. Hasil eksperimen menunjukkan bahwa penggunaan backtracking secara signifikan mengurangi waktu pemrosesan dibandingkan dengan metode tanpa backtracking. Pada eksperimen yang melibatkan 3 aturan, waktu pemrosesan berkurang dari 168,50 ms menjadi 19,53 ms, sementara untuk 6 aturan, waktu pemrosesan turun dari 161,63 ms menjadi 20,88 ms. Demikian pula, dalam pengujian dengan 10 aturan, waktu pemrosesan menurun dari 161,68 ms menjadi 17,38 ms. Secara keseluruhan, integrasi algoritma backtracking meningkatkan efisiensi penelusuran rata-rata sebesar 88%, terbukti menjadi pendekatan yang sangat efektif, terutama dalam sistem pakar yang memiliki banyak aturan dan gejala.

Pesawat terbang adalah moda transportasi tercepat dengan jangkauan hingga antar benua, menjadikannya pilihan utama untuk perjalanan jarak jauh. Meskipun peluang kecelakaan pesawat sangat kecil, yaitu rata-rata 4 kali dalam 1 juta jam terbang dampaknya sangat fatal bagi penumpang, dengan peluang selamat hanya 24% Penyebab utama kecelakaan pesawat umumnya berasal dari tiga faktor: teknis, cuaca, dan kesalahan manusia (human error). Perawatan pesawat dilakukan secara rutin (scheduled maintenance) dan non-rutin (non-scheduled maintenance) berdasarkan interval waktu yang telah ditentukan. Ada berbagai sumber daya yang digunakan untuk sistem kelistrikan pesawat, termasuk generator mesin, unit daya tambahan (APU), daya eksternal, dan udara ram turbin. Penelitian ini bertujuan untuk mengukur tingkat bahaya dalam kondisi penerbangan saat terjadi gangguan pada sistem kelistrikan, mengevaluasi pengaruh performa pesawat terhadap keandalan sistem kelistrikan, serta menilai peran kemajuan teknologi pembangkit listrik terhadap keselamatan penerbangan. Penelitian dilakukan di Hanggar Batam Aero Teknik, Kecamatan Nongsa, Kota Batam, dengan menggunakan metode analisis data kualitatif. Hasil penelitian menunjukkan bahwa kegagalan sistem kelistrikan pada pesawat meliputi kegagalan pada sistem pembangkit dan distribusi. Terdapat komponen dalam sistem distribusi yang, jika rusak, dapat menyebabkan kegagalan kelistrikan yang signifikan. Sistem pembangkit listrik pada pesawat saling mendukung, sehingga perawatan komponen kelistrikan harus dilakukan tepat waktu dan sebaik mungkin.

 The development of COVID-19 cases in Aceh for each region based on spatio-temporal is vital information to know. Spatio-temporal mapping is carried out to knowthe distribution of cases in diversity based on regional and time conditions. The timeseries design study was used as the research design in this study. This study aims toobtain factors that influence the incidence of COVID-19 cases in Aceh using paneldata regression analysis and the GTWR model for more accurate results. There arenine variables from 23 districts/cities in Aceh Province in 2020 and 2021. Based onpartial panel data regression analysis, of the eight independent variables that arefactors for analysis, it shows that only the variable number of doctors (p < 0.000),number of Tuberculosis Cases (p < 0.000), Number of Villages with Puskesmas (p< 0.026), and Number of Poor population (p < 0.035) have a significant effect onthe increase in COVID-19 cases in Aceh. The number of Tuberculosis Cases is avery dominant variable. Then, the results of the GTWR analysis using the AdaptiveKernel Exponential weighting function show that regional and time diversity affectthe factors that cause an increase in COVID-19 cases in Aceh. These factors need tobe a concern in controlling COVID-19 cases in Aceh in the future.
