Abstract

The spread of COVID-19 has become a pandemic throughout the world, including Indonesia. As the main door in Maluku, Ambon has become a new epicenter of the spread of coronavirus. This condition requires local governments to implement Large Scale Social Restrictions (LSSR) after being permitted by the Ministry of Health. This has become a polemic for some Ambonese people especially those who don't have a steady income. Many posts from social media discussing the LSSR that was implemented in Ambon. This study aims to find out how people's sentiment towards the LSSR implementation plan in Ambon through tweets and comments on social media platforms using sentiment analysis. The data obtained amounted to 1075 tweets and comments and separated between 350 training data and testing data of 725. The data classified using the Support Vector Machine (SVM) algorithm. The results of the study showed positive sentiment of 28%, a negative sentiment of 27%, and a neutral sentiment of 45%. It can be concluded that public sentiment towards the implementation of LSSR in Ambon based on posts on social media platforms is quite balanced between positive and negative sentiments and also dominated by neutral sentiments posts.

Abstract

Mayoritas pengguna internet saat ini melakukan penelusuran internet untuk mengetahui berita atau informasi yang sedang berkembang. Pertumbuhan internet dan media sosial telah mendorong munculnya ratusan portal atau berita online dengan topik berita yang sangat beragam. Menelusuri topik berita secara manual merupakan metode yang tidak efektif serta menghabiskan waktu yang banyak.  Pada penelitian ini dilakukan pemodelan topik berita menggunakan Latent Dirichlet Allocation (LDA). Sebelum penerapan model LDA, juga diterapkan proses-proses pendukung yaitu tokenisasi, lemmatisasi, faktorisasi tf-idf, dan non-negative matrix factorization. Hasil penelitian menunjukkan bahwa LDA dapat diterapkan untuk memodelkan topik berita dengan baik dengan nilai  skor loglikelihood -13615.912 dan skor perplexity 378.958. Selain menggunakan LDA, pemodelan topik juga dilakukan dalam bentuk klaster dengan menerapkan k-means clustering. Dengan metode elbow diperoleh jumlah klaster yang ideal untuk k-means clustering adalah 5 klaster serta performa nilai silhouette 0.62

Abstract

Klasifikasi data yang tidak seimbang merupakan masalah yang krusial pada bidang machine learning dan data mining. Ketidakseimbangan data memberikan dampak yang buruk pada hasil klasifikasi dimana kelas minoritas sering disalah klasifikasikan sebagai kelas mayoritas. Dimana kelompok kelas minoritas (minority) adalah kelompok kelas yang memiliki data lebih sedikit, dan kelompok kelas mayoritas (mayority) adalah kelompok kelas yang memilik jumlah data lebih banyak. Data tidak seimbang adalah suatu kondisi dimana jumlah contoh dari salah satu kelas jauh lebih banyak dari kelas yang lain. Alasan buruknya kinerja metode klasifikasi biasa yang digunakan pada data tidak seimbang adalah bahwa tujuan metode klasifikasi dalam meminimumkan galat secara keseluruhan tidak dapat tercapai karena kelas minoritas hanya sedikit memberikan kontribusi, selain itu keputusan akhir yang dihasilkan tidak tepat karena terjadinya bias. Hal ini disebabkan oleh salah satu kelas mendominasi dalam hal jumlah. Dalam penelitian ini akan berfokus pada peningkatan nilai G-Mean dari dataset yang digunakan, dengan menerapkan algoritma Safe-Level-SMOTE. Dari hasil ujicoba yang dilakukan terhadap dua dataset yakni Abalon dan Vowel, untuk skema Smote + k-NN nilai G-Mean yang didapat yakni 0,47 untuk dataset Abalon dan 0.94 untuk dataset Vowel. Seletah dilakukan ujicoba terhadap dataset yang sama menggunakan skema Safe-Level-Smote menggunakan algoritma klasifikasi k-NN didapat hasil G-Mean 0,59  untuk dataset Abalon dan 1.00 Untuk dataset Vowel, rerata dari kenaikan nilai G-Mean terhadap algoritma SMOTE sebesar 12,68%. Hal ini membuktikan bahwasanya algoritma Safe-Level-Smote dapat meningkatkan nilai G-Mean pada klasifikasi data tidak seimbang menggunakan algoritma klasifikasi k-Nearst Neighbors.

Abstract

Pemanfaatan Teknologi Informasi dan Komunikasi (TIK) saat ini menjadi kebutuhan pokok bagi hampir seluruh penduduk bumi ini, dalam mencari informasi dan berkomunikasi kita akan memanfaatkan TIK. Salah satu pemanfaatan TIK melalui jaringan internet adalah cara pengiriman pesan teks melalui email, sosial media, atau alat komunikasi lainnya. Pesan yang disampaikan dari pengirim ke penerima ada kalanya berupa pesan yang bersifat rahasia sehingga tidak semua pihak dapat melihat pesan tersebut. Namun, seiring dengan berkembangnya hal tersebut berkembang pula  pelanggaran atau penyalah gunaan dalam keamanan data yang dikirim seperti dengan cara merusak, menyadap, merubah pesan tersebut untuk tujuan kepentingan si pelaku. Tindakan tersebut dapat membuat informasi atau pesan yang bersifat rahasia dapat dilihat oleh orang yang tidak bertanggung jawab. Dalam menangani masalah keaman data ini, perlu dilakukan penggunaan teknik peningkatan keamanan. Salah satu teknik yang dapat digunakan untuk mengamankan data adalah dengan menggunakan algoritma Modular Multiplication based Block Chiper (MMB), yang merupakan metode yang sederhana tidak terlalu kompleks namun pesan yang disembunyikan cukup aman.

Abstract

The age range in Senior High School (SMA) is adolescents, adolescents generally find it difficult to open up to others, and it is also difficult to admit that they need guidance, even teenagers refuse the help adults want to provide. In connection with this, facilities are provided in schools to deal with problem students, in dealing with these problems a special teacher is provided, namely the Guidance and Counseling teacher (CT). Guidance for students is needed in making the right choices or for solving problems faced by humans in everyday life. Guidance must be done through a continuous process because as long as humans live, they definitely need help. With the presence of CT, it does not mean that the school is free from the problem of providing guidance and counseling to students, this is a new problem for schools because it is often found dishonesty or lack of openness of students who have problems in providing information to CT.To overcome the problem of the lack of openness of students in providing information during counseling, in this study a forward chaining method was designed which was implemented into an expert system that could help with problematic student counseling activities, so that using this expert system could assist counseling activities. teachers to facilitate counseling. towards students.
