Abstract:  Covid-19 has been set as a Pandemic by the World Health Organization (WHO). The very large impact and the infection that is fast enough are the reasons for making Covid-19 as a pandemic and efforts to overcome. One anticipation that can be done is to do lockdown. Making the decision to carry out a lockdown is intended to reduce the spread that occurs. Lockdown is certainly not a 100% good solution for all of individual. There are individual who agree that the lockdown will be implemented, also there are those who think that the lockdown is better not to be carried out considering the negative impacts that can occur. Therefore in this study will be presented the predictive modeling for sentiment analysis related to "lockdown" specially on social media Twitter. The method used to labeled was using Vader then the tweets are extracted using TF-IDF, and modeling is made for the prediction of sentiment using Naïve Bayes and Support Vector Machine. The results obtained from the two algorithms are more than 80%. Keywords: Covid-19, lockdown, TF-IDF, Naïve Bayes, Support Vector Machine Abstrak: Covid-19 telah ditetapkan sebagia Pandemi oleh World Health Organization (WHO). Dampak yang sangat besar dan penyebaran yang cukup cepat menjadi alsan untuk menjadikan Covid-19 sebagai Pandemi dan perlu dilakukan upaya penanggulangan. Salah satu upaya yang bisa dilakukan adalah dengan melakukan lockdown. Pengambilan keputusan untuk melakukan lockdown diperuntukan guna mengurangi penyebaran yang terjadi. Lockdown tentunya bukanlah solusi yang 100% baik bagi segala pihak. Terdapat pihak - pihak yang menyetujui akan dilaksanakannya lockdown, ada pula yang beranggapan bahwa lockdown lebih baik tidak dilaksanakan dengan pertimbangan dampak negatif yang bisa terjadi. Oleh karena itu, pada penelitian ini akan disampaikan mengenai pembuatan pemodelan prediksi terkait analisa sentimen terkait “Lockdown” yang dikhususkan pada media sosial Twitter. Metode yang digunakan adalah dengan melakukan labeling menggunakan Vader dan selanjutnya tweet tersebut dilakukan ekstraksi menggunakan TF-IDF, dan dibuatkan pemodelan untuk prediksi sentimen menggunakan Naïve Bayes dan Support Vector Machine.

Diabetes melitus adalah penyakit metabolik yang ditandai terjadinya kenaikan gula darah yang disebabkan oleh terganggunya hormon insulin yang memiliki fungsi sebagai hormon dalam menjaga homeostatis tubuh menggunakan cara penurunan kadar gula darah (American Diabetes Association, 2017). World Health Organization (WHO) memperkirakan jumlah penderita diabetes melitus orang dewasa diatas 18 tahun dalam tahun 2014 berjumlah 422 juta (WHO, 2016:25). Prevalensi diabetes melitus Asia Tenggara sudah berkembang dalam tahun 1980 sebanyak 4,1% dan tahun 2014 menjadi sebanyak 8,6%. Menurut Riset Kementerian Kesehatan pada tahun 2018, Prevalensi diabetes Indonesia sebanyak 2,0%, sedangkan di Provinsi Jawa Timur sebanyak 2,6% pada penduduk umur diatas 15 tahun (KEMENKES RI, 2019). Penelitian ini dikembangkan melalui pengolahan data sekunder database kesehatan Dataset Diabetes yang diambil dari dataset Kaggle dan dapat diakses melalui https://www.kaggle.com/johndasilva/diabetes. Dimana datanya sendiri terdiri dari 2000 record dengan beberapa variabel prediktor medik (Pregnancies/Kehamilan, Glucose/Glukosa, BloodPressure/Tekanan Darah, SkinThickness/Ketebalan Kulit, Insulin, BMI/Indeks Masa Tubuh, DiabetesPedigreeFunction/Keturunan, Age/Umur and Outcome/Hasil). Kemudian data tersebut akan diolah dengan menggunakan metode Support Vector Machine dan metode Naive Bayes untuk mengetahui akurasi hasil diagnosa diabetes. Berdasarkan hasil dari penelitian yang sudah dilakukan metode Support Vector Machine memiliki nilai akurasi yang jauh lebih tinggi dibandingkan dengan menggunakan metode Naive Bayes. Nilai akurasi untuk model metode Support Vector Machine adalah 78,04% dan nilai akurasi untuk metode Naive Bayes 76,98%. Berdasarkan nilai ini, perbedaan akurasinya adalah 1,06%. Sehingga dapat disimpulkan bahwa penerapan metode Support Vector Machine mampu menghasilkan tingkat akurasi diagnosis diabetes yang lebih baik dibandingkan dengan menggunakan metode Naive Bayes.

Breast cancer is one of the highest causes of death among women, this disease ranks second cause of death after lung cancer. According to the world health organization, 1 million women get a diagnosis of breast cancer every year and half of them die, in general this is due to early treatment and slow treatment resulting in new cancers being detected after entering the final stage. In the field of health and medicine, machine learning-based classification has been carried out to help doctors and health professionals in classifying the types of cancer, to determine which treatment measures should be performed. In this study breast cancer classification will be carried out using the Naive Bayes algorithm to group the types of cancer. The dataset used is from the Wisconsin breast cancer database. The results of this study are the ability of the Naive Bayes algorithm for the classification of breast cancer produces a good value, where the average percentage of correctly classified data reaches 96.9% and the average percentage of data is classified as incorrect only 3.1%. While the level of effectiveness of classification with naive bayes is high, where the average value of precision and recall is around 0.96. The highest precision and recall values are when the test data uses a percentage split of 40% with the respective values reaching 0.974 and 0.973.
