SISTEM PAKAR UNTUK MENDETEKSI GANGGUAN PENCERNAAN DENGAN METODE BACKWARD CHAINING
Full text linkGangguan pencernaan adalah berbagai jenis masalah yang terjadi pada sistem pencernaan tubuh, mulai dari mulut, kerongkongan, lambung, usus halus, usus besar, dan anus. Gangguan pencernaan yang terjadi bisa sangat menyulitkan dan sebaiknya tidak diabaikan.
Permasalahan yang saat ini sering terjadi yaitu masih banyak masyarakat awam yang kurang memahami dan pengetahui gejala-gejala dari jenis gangguan pencernaan dan terlambat menangani. Apabila terjadi gangguan pencernaan maka mereka lebih mempercayakan kepada dokter ahli tanpa memperdulikan apakah gangguan tersebut masih dalam tingkat rendah atau kronis.Untuk itu perlu mengetahui gejala-gejala, penyebab dan pencegahan dari jenis gangguan pencernaan, agar gangguan yang diderita tidak berdampak dan dapat segera diobati. Diperlukan sebuah Sistem Pakar yang dapat membantu masyarakat dalam mengetahui gejala-gejala, penyebab dan pencegahan dari jenis gangguan pencernaan.
Untuk itu penulis tertarik melakukan penelitian Sistem Pakar untuk mendeteksi gangguan pencernaan dengan metode Backward Chaining. Sistem Pakar itu sendiri dirancang dengan berbasis web, karena dengan aplikasi berbasis web dapat membantu proses penyebaran informasi dan pengetahuan dengan daerah penyebaran yang lebih luas

No full textWater is used as one of the primary needs for humans and is also an exemplary process for the human body and other living things, so that clean water is needed when it is consumed. There are various ways to purify water, starting from using natural ingredients to using artificial materials. One method of purification that can be done is by finely grinding the moringa seeds so that the dirt in the water becomes a coagulant. This process is called the coagulation-flocculation method. The purpose of this method is that the purified water has a pH value of around seven and also has a high clarity level value. In order for the data collection process to be accurate, pH and turbidity sensors are needed to measure directly. The pH sensor is used as a measure of acidity and turbidity as a measure of clarity. Based on the results of research and testing tools in the field, the more biocoagulant powder given, namely moringa seeds, can increase the pH value and can reduce the turbidity value in water, with research evidence that in Experiment 1, the pH and turbidity values before purification were 7, 00 and 2940.70 NTU so that when entering Tube 2 and Tube 3 the pH and turbidity values become 7.38 and 2876.30 NTU. In Experiment 2, the pH and turbidity values before purification were 7.0 and 2940.70 NTU so that when entering Tube 2 and Tube 3, the pH and turbidity values were 8.08 and 2789.5 NTU. In Experiment 3, the pH and turbidity values before purification were 7.0 and 2940.70 NTU, and after being purified through Tube 2 and Tube 3, the pH and turbidity values were 8.25 and 2394.63 NTU
