Abstract

Latar Belakang: Salah satu kelainan rongga mulut yang sering terjadi adalah Stomatitis Aftosa Rekuren (SAR). SAR adalah kelainan yang ditandai dengan ulser berulang pada mukosa rongga mulut tanpa tanda-tanda penyakit lain. Gambaran klinis dari SAR yaitu bulat atau oval berbatas jelas kemerahan dengan dasar berwarna kekuningan sampai abu-abu.  Etilogi SAR adalah multifaktorial dikaitkan dengan trauma, stres, ketidakseimbangan hormon, genetik, kelainan imun, beberapa penyakit sistemik serta defisiensi mineral, namun etiologi sebenarnya masih belum pasti. Stres adalah respon terhadap stimulus dan stressor. Dental education dapat menyebabkan stres yang cukup besar pada mahasiswa kedokteran gigi. Tingginya tingkat stres yang dirasakan mahasiswa profesi dokter gigi sering dikaitkan dengan kelelahan emosi dan tekanan psikologis sehingga dapat menyebabkan SAR. Tujuan: Penelitian ini bertujuan untuk mengetahui pengaruh stres terhadap kejadian stomatitis aftosa rekuren pada mahasiswa profesi dokter gigi IIK Bhakta. Metode: Analitik observasional  dengan pendekatan cross sectional, untuk menguji hipotesis dilakukan uji chi square. Hasil: Berdasarkan uji chi square didapatkan nilai p=0,000 nilai tersebut lebih kecil dari 0,05 maka hal tersebut menunjukkan hubungan yang signifikan. Kesimpulan: Stres berpengaruh terhadap kejadian stomatitis aftosa rekuren pada mahasiswa profesi dokter gigi IIK Bhakta.

Abstract

ABSTRACT Sludge worm (Tubifex sp.) as natural feed on catfish (Pangasionodon sp.) larvae rearing is available in limited amount especially during rainy season. It becomes a constraint factor for larvae rearing sector. This research was conducted to evaluate the appropriate initial age of catfish larvae to get artificial feed as sludge worm replacement. Evaluation was conducted on the growth and survival of catfish larvae in 14 days of culture. There were four treatments of feeding in triplicates i.e. larvae were given natural feed without artificial feed, given artificial feed started from d3, d6, and d9) with three replications. The results showed that larvae fed on artificial feed on d3 had the lowest growth compared to the other treatments, whereas the survival was not significantly different (P>0.05) among the treatments. As a conclusion, artificial feed could be used to replace natural feed for catfish larvae started at the age of nine days. Keywords: sludge worm, catfish larvae, artificial feed  ABSTRAK Cacing sutra (Tubifex sp.) tersedia dalam jumlah terbatas terutama pada musim penghujan sebagai pakan alami dalam usaha pembenihan ikan patin (Pangasionodon sp.). Ini menjadi kendala dalam usaha pembenihan. Penelitian ini dilakukan untuk mengevaluasi umur larva ikan patin yang tepat untuk mulai diberi pakan buatan menggantikan cacing sutra. Evaluasi dilakukan pada pertumbuhan dan kelangsungan hidup larva ikan patin umur 14 hari. Selama pemeliharaan, larva diberi pakan dengan empat perlakuan; pemberian pakan alami tanpa pakan buatan, pemberian pakan buatan mulai d3, d6, dan d9 dengan tiga ulangan untuk masing-masing perlakuan. Hasil penelitian menunjukkan bahwa perlakuan pemberian pakan buatan mulai d3 memiliki pertumbuhan panjang yang terkecil dibandingkan perlakuan lain, sedangkan tingkat kelangsungan hidup larva tidak berbeda nyata (P>0,05) antarperlakuan. Berdasarkan hasil penelitian, dapat disimpulkan bahwa pakan buatan dapat digunakan sebagai pengganti pakan alami mulai larva ikan patin umur sembilan hari. Kata kunci: cacing sutra, larva ikan patin, pakan buatan

Abstract

Modern technology has developed rapidly, providing various solutions to facilitate activities and work. The Medan City Cooperatives and Small and Medium Enterprises (UKM) Service, which handles various complaints from the public regarding SME services, still uses manual methods in its complaint process. This manual method often causes various problems, such as delays in handling complaints and difficulties in monitoring complaint status. To overcome these problems, this study aims to design and build a website-based virtual public complaint service system application. This study uses data collection methods through observation, interviews, and documentation. In developing the application, the Personal Home Page (PHP) method is applied because of its flexibility in handling changing needs during the development process. Direct communication with clients is the main focus in this method. This application was developed using Visual Studio Code as an editor, and MySQL as a database, thus accelerating the application development process. The results of this study are in the form of a public complaint information system application that can facilitate the public and the Medan City Cooperatives and Small and Medium Enterprises Service in managing and responding to complaints effectively
