Ujian Online merupakan suatu cara yang digunakan untuk mengevaluasi hasil belajar siswa dalam mengukur taraf pencapaian siswa sebagai peserta didik, sehingga siswa dapat mengetahui batas kemampuan dirinya dalam memahami bidang studi yang ditempuh selama mengikuti pendidikan dengan pelaksanaan ujian menggunakan internet. Rancang bangun sistem ujian online menggunakan algoritma cosine similarity yaitu melakukan perkalian skalar antara query dengan dokumen kemudian dijumlahkan, setelah itu melakukan perkalian antara panjang dokumen dengan panjang query yang telah dikuadratkan, setelah itu di hitung akar pangkat dua. Selanjutnya hasil perkalian skalar tersebut di bagi dengan hasil perkalian panjang dokumen dan query, hasil rancangan sistem ini dapat mempermudah proses pendataan ujian sekolah yang sistematis dan terkomputerisasi, dan dengan adanya sistem ujian sekolah ini dapat mengurangi penumpukan kertas. Rancangan sistem ujian onlie menggunakan use case, diagram activity, class diagram dan rancangan database. Pengujian menggunakan metode black box untuk menguji Interface sistem ujian, Pengujian fungsi dasar sistem, pengujian form handle sistem, dan pengujian keamanan sistem aplikasi
A person who is in the elderly phase will experience various decreases, ranging from decreased memory or senility, hormone production, skin elasticity, muscle mass, bone density, strength and function of body organs, and the immune system. As a result, it is difficult for the elderly or the elderly to fight against various kinds of disease-causing bacteria or viruses, comorbidities, and adaptation to the social environment. Due to the complexity of this health problem, improvements can not only be made in the aspect of health services but also improvements in the environment and engineering of population factors or hereditary factors, but it is necessary to pay attention to behavioral factors that have a considerable contribution to the emergence of health problems. This research uses the certainty factor (CF) method which can provide a measure of belief in a symptom as a measure of how much the value is in the later diagnosis. The purpose of making this expert system is so that patients, patient families, and medical teams can monitor the health of the elderly daily. The results of this study indicate that using the CF method has an accuracy rate of 91 percent for the prediction of patients who have cholesterol
ABSTRACT The purpose of this study was to determine the role of civic education in fostering discipline norms of elementary school students. With education, it will arise in a person to compete and motivate ourselves to be better in all aspects of life. This study uses a qualitative method approach. The results showed that civic education teaches students about values, norms and morals. By practicing values, norms and morals, it will create a disciplined character in students. The existence of discipline makes the educational process that takes place at school will go well, because students do not violate school rules. The conclusion of this study is that the discipline of norms in elementary school students is really needed, because the discipline of norms is included in the formation of character in children. Keywords: Citizenship Education, Discipline, Student Norms.
Many animal keepers at home who do not know the disease contained in the animal's body. Especially for dogs, the lack of information begins to provide care, hygiene, vaccinations for the health of pet dogs and sickles that will be caused by dogs to their owners. Expert systems can provide solutions to the lack of information obtained by pet dog owners, especially dogs. With this expert system, the owner can know the dog's disease and realize the right prevention in treatment. In this paper 25, physical symptoms of the disease are used and found 8 types of common dog diseases. Five options are given to answer the calculation question using each method: no, quite sure, sure enough, certain, and certainty sure. Accuracy Analysis of each method is tested by assessing the results of each analysis method based on user feedback. The results of this study are the application of an expert system that can diagnose dogs using herbal medicines from plants. The purpose of this study is to implement the certainty factor method in the diagnosis system of canine diseases that can provide space in providing value confidence in knowledge. The conclusion in this study will show some questions as indicators of the characteristics of canine disease, until the final question. The conclusion of the study using the certainty factor method will show the characteristics of the disease in dogs. By being obtained from Rabies (0.9) with easy to get angry refuse nomal food; Hepatitis (0,9) with swelling of the liver occurs; Distemser (0,8) with stomach part blister and festering discharge from the eye; canine parvorius (0,8) with loss of appetite and poop there is blood, herpesvirus (0,8) with often roared and complaints, papilomatosis (0,9) with Smelly dog breath, and leptospirosis (0,7) with complaints, and dirofilaria immitis (0,9) with Unstable body temperature
Indonesia is a country that has economically valuable mineral deposits such as nickel, aluminum, cobalt and manganese. These economical metallic minerals have an important role in the sustainability of the battery industry's long-term plans required during the energy transition. Manganese (Mn) is the fourth most widely used metal in the world which can be used as an industrial alloy. This study aims to determine the type of manganese that can be found in the research area, determine the hostrock (carrying rock) of sediment, and determine the type of deposit in the study area. Research data collection was carried out at 13 different points centered on the Gunung Kasih area and its surroundings. The data taken in the form of rock samples. Processing of data using petrological analysis and taking microscopic photos in the laboratory. The results showed that there were three forms of manganese oxide minerals, namely acicular, botryoidal and dendritic. Manganese oxide minerals in this area were found filling the fractures in several types of rock, namely red clay, clay, andesite, and lapilli tuff. The type of manganese oxide deposits in the study area is included in the type of residual manganese deposits associated with hydrothermal deposits. Rocks carrying manganese oxide minerals can come from red claystones of the Menanga Formation or igneous rocks and pyroclastic rocks of the Hulusimpang Formation.
