Abstract

ABSTRAKPemijahan ikan merupakan salah satu proses tahapan perkembangbiakan induk ikan jantan dan betina yang yang matang gonad. Pemijahan ikan yang sering dilakukan adalah pemijahan secara semi buatan dan buatan dengan menggunakan hormone sintesis seperti ovaprim maupun mengunakan hormone secara alami yang diproduksi oleh kelenjar hipofisa pada ikan donor. Tujuan penelitian adalah untuk mengetahui pengaruh dosis ekstrak kelenjar hipofisa ikan mas dengan perlakuan dosis 0.5 ml, 1.0 ml, 1.5 ml terhadap derajat pembuahan telur (FR), derajat penetasan (HR), dan kelangsungan hidup (SR) ikan lele sangkuriang. Metode yang digunakan adalah metode eksperimen penyuntikan dosis kelenjar hormone hipofisa ikan mas untuk menganalisis pengaruhnya dalam pemijahan induk ikan lele sangkuriang secara semibuatan. Hasil penelitian terhadap penggunaan dosis kelenjar hipofisa ikan mas untuk pemijahan ikan lele sangkuriang didapat nilai rata-rata derajat pembuahan telur tertinggi pada perlakuan dosis 1.5 ml sebesar 87.1 %, nilai rata-rata derajat penetasan tertinggi pada perlakuan dosis 1.5 ml sebesar 30.7 % dan nilai rata-rata  tingkat kelangsungan hidup tertinggi pada perlakuan dosis 1.5 ml sebesar 97.4 %. Kesimpulan dari penelitian ini adalah penggunaan dosis kelenjar hipofisa ikan mas yang terbaik yaitu pada perlakuan D dengan dosis 1.5 ml.Kata kunci: Kelenjar hipofisa ikan mas, pemijahan semi buatan, ikan lele sangkuriangABSTRACTFish spawning is one of the stages breeding process of mature male and female brood fish. Fish spawning that is often done is semi-artificial and artificial spawning using synthetic hormones such as ovaprim or using natural hormones produced by the pituitary gland in donor fish. The purpose of this study was to determine the effect of carp pituitary gland extract with doses of 0.5 ml, 1.0 ml, 1.5 ml on the degree of egg fertilization (FR), hatching rate (HR), and survival (SR) of sangkuriang catfish. The method used was the experimental method of injecting doses of the pituitary gland hormone of carp to analyze its effect on the spawning of the broodstock of sangkuriang catfish in a semi-artificial manner. The results of the study on the use of the pituitary gland dose of carp for spawning sangkuriang catfish obtained the highest average degree of egg growth at the 1.5 ml dose treatment of 87.1%, the highest hatching rate average value at the 1.5 ml dose treatment of 30.7% and the average value The highest average survival rate at a dose of 1.5 ml was 97.4%. The conclusion of this study is the use of the best dose of carp pituitary gland, namely in treatment D with a dose of 1.5 ml.Keywords: Carp pituitary gland, semi artificial spawning, sangkuriang catfish

Abstract

The needed for carp in Jayapura City was greatly increasing along with the high growth and increase of population in Jayapura City. Cultivation of carp (Cyprinus carpio) can be done intensively and semi-intensively by taking into account the economic value. However, from cultivation activities, the problems that were often faced in cultivation activities were the attack of dangerous types of pathogens such as parasites. Parasite was a fish disease that occurs more frequently. Parasites were organisms that live on the body of other organisms and generally have a negative effect on their host. This study aimed to identify and the prevalence of ectoparasites to determine the type and level of ectoparasite attack on carp (C. carpio) seeds and to reduce the impact of ectoparasites which was feared to reduce the amount of carp production from cultivation. The method used was a direct survey to the Local Fish Seed Center and fish farmers in the Koya Barat area. The fish used were carp in the seed phase where the fish's immune system was still weak, making it more susceptible to contracting parasites. This study showed that there were 4 types of parasites found during the study that infected carp seeds, namely Dactylogyrus sp, Gyrodactylus sp, Trichodina sp, and Lernea sp. The average prevalence rate of Dactylogyrus sp. at stations I, II, III, and IV was 25%, Gyrodactylus sp. 8.3%, Trichodina sp. 8.3% and Lernea sp. 5% with the lowest prevalence rate.

Abstract

Sistem Informasi Geografis (SIG) telah menjadi alat yang penting dalam pengelolaan dan promosi objek wisata di berbagai destinasi. Penelitian ini bertujuan untuk mengembangkan sebuah sistem informasi geografis yang dapat memetakan objek wisata di Kota Jayapura, Indonesia. Sistem ini akan memberikan informasi yang komprehensif tentang objek wisata, termasuk lokasi geografis, fasilitas yang tersedia, aksesibilitas, dan informasi terkait lainnya. Penelitian ini akan menggunakan data geografis dari berbagai sumber, termasuk data spasial, citra satelit, dan peta digital yang ada, sistem ini juga akan memberikan fitur interaktif, seperti penandaan objek wisata pada peta, pencarian berdasarkan kategori, dan fitur ulasan pengguna. Hasil dari penelitian ini diharapkan dapat memberikan manfaat yang signifikan dalam pengelolaan objek wisata di Kota Jayapura. Diharapkan sistem informasi geografis yang dikembangkan dapat meningkatkan visibilitas dan daya tarik objek wisata, membantu pemerintah dalam perencanaan dan pengembangan infrastruktur, serta memberikan pengalaman yang lebih baik bagi wisatawan yang berkunjung ke Kota Jayapura.

Abstract

The number of words or terms that appear and are used in human life makes it difficult for a person to master all of these words. To overcome this, these words or/terms are compiled in a dictionary, one of which is a dictionary of medical terms. This research aims to create software that can perform its function as a medical terminology dictionary program and implement the Hash method into software that can be used for data search. This research applies the hash method to find the hash value using a rolling hash. The hash method uses input text to be transformed into numbers, thus speeding up the computational process. The application of the hash method in the addressing/storage process in the Database is very efficient in terms of time and place. The output appears in the form of word meaning and hash value. The hash value is raised to know the value of the searched term using the rolling hash formula. With this research, it is hoped that searching for the meaning of medical terms in a computerized manner can be consistent with manual searches.
