The development of molecular biology and genetic engineering, now allow the formation of an effective and specific cancer treatment. Modern cancer treatment has grown rapidly, thus giving a chance to discover a new method that is more promising than the previous treatment. Virotherapy is one of cancer therapy that use the replication-competent viruses to destroy cancer cells. Oncolytic virus (virus used as virotherapy) must be modified by genetic engineering before it can be used as virotherapy.Once modified, oncolytic virus destroys cancer cells through the replication, apoptosis induction, cell lysis through the release of progeny viruses, and activation of immune system. The immune system will be responsible for neutralizing the virus after tumour lysis process, and the immune system will also destroy the remaining tumor cells, although virus already neutralized from the body.

Rendahnya kemampuan komunikasi matematis dan kesulitan siswa dalam menyelesaikan soal verbal melatarbelakangi penelitian ini. Tujuan penelitian untuk mengetahui kesulitan siswa dalam menyelesaikan soal kemampuan komunikasi matematis. Metode penelitian ini yaitu kualitatif. Penelitian dilaksanakan di Daerah Ciawitali dengan sampel sebanyak 5 siswa SMP. Instrumen penelitian berupa empat soal tes uraian dan wawancara. Hasil menunjukkan bahwa beberapa kesulitan yang muncul pada saat siswa mengerjakan soal komunikasi matematis pada materi penyajian data yaitu kesulitan dalam menyimpulkan, memahami dan menginterpretasi ide matematika, melakukan perhitungan, dan kesulitan menyusun kata-kata untuk menjelaskan kembali pernyataan. Berdasar pada kesulitan yang terjadi, kemampuan komunikasi dapat ditingkatkan dengan berfokus mengatasi kesulitan-kesulitan tersebut. The low mathematical communication skills and students' difficulties in solving verbal problems are the backgrounds of this research. The purpose of the study was to determine the students' difficulties in solving mathematical communication skills problems. This research method is qualitative. The research was carried out in the Ciawitali area with a sample of 5 junior high school students in the area. The research instrument was in the form of a description test with four questions and interviews. The results of the analysis show that some of the difficulties that arise when students work on mathematical communication problems in data presentation material are difficulties in concluding, understanding and interpreting mathematical ideas, performing calculations, and difficulties in composing words to explain statements. Based on the difficulties that occur, communication skills can be improved by focusing on overcoming these difficulties.

Kemampuan komunikasi matematis dan self-confidence penting dalam pembelajaran matematika. Namun, banyak siswa masih mengalami kesulitan dalam mengungkapkan ide matematis dan kurang percaya diri dalam pembelajaran. Diperlukan model pembelajaran inovatif seperti Inquiry Learning dan Discovery Learning yang melibatkan siswa secara aktif. Penelitian bertujuan menganalisis perbedaan peningkatan kemampuan komunikasi matematis dan self-confidence antara siswa yang dibelajarkan dengan model Inquiry dan Discovery Learning, serta mengkaji hubungan antara kedua kemampuan tersebut. Metode yang digunakan adalah kuasi eksperimen dengan desain pretest-posttest nonequivalent control group. Data dikumpulkan melalui tes dan kuesioner, dianalisis menggunakan Independent Sample t-test dan uji t’ untuk membandingkan peningkatan, serta uji korelasi Pearson untuk melihat hubungan antar variabel. Hasil penelitian menunjukkan adanya perbedaan peningkatan kemampuan komunikasi matematis dan self-confidence antara kedua model pembelajaran. Namun, tidak ditemukan hubungan antara peningkatan komunikasi matematis dan self-confidence dalam masing-masing model. Mathematical communication skills and self-confidence are two important aspects in learning mathematics. However, many students still have difficulty expressing mathematical ideas and lack confidence in learning. Therefore, innovative learning models such as Inquiry Learning and Discovery Learning are needed that actively involve students. This study aims to analyze the differences in the improvement of mathematical communication skills and self-confidence between students who are taught with the Inquiry and Discovery Learning models, and to examine the relationship between the two abilities. The method used is a quasi-experiment with a nonequivalent control group pretest-posttest design. Data were collected through tests and questionnaires, then analyzed using the Independent Sample t-test and t' test to compare improvements, and the Pearson correlation test to see the relationship between variables. The results showed differences in the improvement of mathematical communication skills and self-confidence between the two learning models. However, no relationship was found between the improvement of mathematical communication and self-confidence in each model.
