Pengembangan E-LKPD Berbasis Saintifik Materi Sistem Pernapasan pada Manusia Kelas XI SMA

Student worksheet (LKPD) is a teaching material which can be developed by a teacher to be used in learning process. Based on the observation result in SMAN 2 Kota Jambi, most of the students are still struggling in understanding the human respiratory system material. Electronic LKPD or e-LKPD contains learning material with images and videos which make students learn easier. Teaching material such as e-LKPD can be integrated with scientific approach which stimulates students’ involvement in learning process. This research aims to develop scientific based e-LKPD for human respiratory system material for Senior High School grade XI, to find out about the properness, teachers’ and students’ response, and the effectiveness of e-LKPD in improving learning outcomes. The development of e-LKPD used ADDIE model which consists of analysis, design, development, implementation, and evaluation. The e-LKPD product has been validated by the media and material experts with very good result. The result of biology teacher’s response and the result of students’ trial on small and big group showed very good result. The result of effectiveness test using paired sample t test showed that there is an effect of using scientific based e-LKPD on human respiratory system material in improving student learning’s outcomes. Thus, scientific based e-LKPD for human respiratory system material is an appropriate teaching material and can improve students’ learning outcomes. Abstrak.

Dengan demikian e-LKPD berbasis saintifik materi sistem pernapasan pada manusia yang dikembangkan layak digunakan sebagai bahan ajar dan dapat meningkatkan hasil belajar peserta didik.

Implementation of K-Means Clustering Algorithm in Determining Classification of the Spread of the COVID-19 Virus in Bali

The COVID-19 virus or also known as SARS-Cov-2 is an infectious disease caused by the Coronavirus which attacks the human respiratory system. The COVID-19 case has affected all provinces in Indonesia, including Bali. There is a total of 7481 cases in Bali and this is due to the lack of understanding of the community towards the COVID-19 prone areas in Bali. Therefore, it is necessary to group the areas prone to COVID-19 in Bali. One of the clustering algorithms is K-Means, this algorithm uses several groups for the placement of some data with a partition system. The grouping will be carried out using data from the Bali COVID-19 Task Force website on September 18, 2020, using RapidMiner application. The results obtained divided Bali into 3 clusters with Denpasar as the center of the highest spread of COVID-19 in Bali as the red zone, then Badung, Buleleng, Bangli, Gianyar, and Karangasem in the yellow zone, and other districts in the green zone.

Anosmia and covid-19 in Yogyakarta, Indonesia: a case series

ABSTRACTCovid-19 (coronavirus disease 2019) had spread to the whole world. This kind of virus attacks the human respiratory system, and it caused death. In other words, there were many symptoms of Covid-19, which attacks the respiratory system. One of the symptoms was anosmia or smell disorder. This research might provide information about the anosmia in Covid-19 patients. This study aimed to investigate and present a series about anosmia and Covid-19 in Yogyakarta on June 2020. Three cases from three patients of RT-PCR-confirmed SARS-CoV-2-infected patients diagnosed with smell disorder were presented, starting from the symptom until the patients were getting treatments. This research also explained anosmia as one of the symptoms of Covid-19. Anosmia or losing olfactory function or smell disorder which could distract people’s healthy. Then, in this situation, it could be one of the symptoms of Covid-19. Keywords : anosmia, smell disorder, covid-19Corresponding Author : [email protected]

Algoritma Clustering Untuk Membentuk Cluster Zona Penyebaran Covid-19

Covid-19 yaitu suatu penyakit yang menyerang sistem pernapasan manusia dan dapat menular dengan mudah. Sumatera Utara salah satu daerah yang dilanda pandemi Covid-19. Melalui Gugus Tugas Percepatan dan Penanganan Covid-19 provinsi Sumatera Utara telah melakukan berbagai upaya untuk pencegahan penyebaran Covid-19 seperti belajar dan ibadah dirumah, himbauan pakai masker dan lain sebagainya. Untuk mempermudah identifikasi penyebaran Covid-19 Tim Gugus membagi zona penyebaran Covid-19 berdasarkan jumlah kasus positif. pembagian zona dengan menggunakan satu variabel yaitu positif menyebabkan penanganan Covid-19 tidak maksimal karena hanya terkonsentrasi pada zona dengan kasus positif yang terbanyak sedangkan potensi penyebaran bukan hanya dari kasus positif. Oleh karene itu, dibutuhkan teknik yang lain dapat mengelompokkan / cluster zona penyebaran Covid-19. Salah satu teknik yang sesuai untuk pengelompokkan / cluster yaitu algoritma clustering K-Medoids. Hasil dari implementasi algoritma Algoritma K-Medoids yaitu cluster zona penyebaran Covid-19 di Sumatera Utara dibagi dalam 3(tiga) Cluster yaitu cluster 1, cluster 2 dan cluster 3. Cluster 1 identik dengan zona merah, Cluster 2 identik dengan zona kuning dan cluster 3 identik dengan zona hijau. Abstract Covid-19 is a disease that attacks the human respiratory system and can be transmitted easily. North Sumatra is one of the areas hit by the Covid-19 pandemic. Through the Task Force for the Acceleration and Handling of Covid-19, the province of North Sumatra has made various efforts to prevent the spread of Covid-19, such as studying and worship at home, appealing to wear masks and so on. To make it easier to identify the spread of Covid-19, the Cluster Team divides the Covid-19 spread zones based on the number of positive cases. zoning by using one variable, namely positive, causes the handling of Covid-19 to be not optimal because it is only concentrated in the zone with the most positive cases, while the potential for spread is not only from positive cases. Therefore, another technique is needed to group / cluster the Covid-19 spread zones. One technique that is suitable for grouping / clustering is the K-Medoids clustering algorithm. The results of the implementation of the K-Medoids Algorithm algorithm, namely the Covid-19 spread zone cluster in North Sumatra is divided into 3 (three) clusters, namely cluster 1, cluster 2 and cluster 3. Cluster 1 is identical to the red zone, Cluster 2 is identical to the yellow zone and cluster 3 is identical to the green zone

The Human Respiratory Systems Learning Video: Validity and Feasibility

This research is motivated by the lack of availability of learning media in the form of learning videos during the COVID-19 pandemic, especially on the science content of the human respiratory system material. This study aims to describe the design and validity of the development of learning videos. This study uses the ADDIE development model (Analyze, Design, Development, Implementation, and Evaluation). The subjects in this study were content experts, learning design experts, learning media experts, and fifth grade elementary school students. The methods and instruments used to collect data in this study used a questionnaire. The data analysis technique used is descriptive qualitative analysis and descriptive quantitative analysis. The results of the analysis of the validity test obtained the following results. content experts got 87.5% results with good qualifications, learning design experts got 95.0% results with very good qualifications, learning media experts got 95.0% results with very good qualifications, and individual trials got 95.8 results % with very good qualifications. Thus, based on this analysis, it can be stated that this learning video product is valid and suitable for use in the science content of the human respiratory system material.
