Based on the percentage of the mathematical reasoning abilities test of students, the percentage of pretest was 63% of the students have the mathematical reasoning abilities with good category and posttest was 34% of the students have the mathematical reasoning abilities with good category. In addition, there were  84% of the students prefer the blended learning than the fully online learning, because it was effective to the mathematical reasoning abilities of students. Based on the results of the research it can be concluded that  the fully online learning was no more effective than blended learning.

Berdasarkan penjelasan dalam Undang-Undang Nomor 1 Tahun 2011, penyelenggaraan kawasan permukiman dilaksanakan dengan maksud untuk mewujudkan wilayah yang berfungsi sebagai lingkungan hunian dan tempat kegiatan yang mendukung perikehidupan dan penghidupan yang terencana, menyeluruh, terpadu, dan berkelanjutan sesuai dengan rencana tata ruang. Perkembangan wilayah sangat dipengaruhi oleh tingkat pertumbuhan penduduknya. Dengan semakin meningkatnya pertumbuhan penduduk ini maka semakin tinggi pula kebutuhan lahan di wilayah tersebut. Sebagai daerah yang sedang berkembang Kabupaten Lombok Utara akan menghadapi permasalahan yang umum dijumpai oleh wilayah kota/perkotaan yaitu munculnya kawasan permukiman kumuh, seperti halnya di Dusun Karang Desa yang berada di Kecamatan Tanjung yang merupakan Kawasan Ibukota Kabupaten Lombok Utara. Penelitian ini dilakukan dengan melakukan Identifikasi Risiko pada deliniasi kawasan yang memiliki potensi kumuh atau menjadi kumuh baru.             Berdasarkan hasil hasil identifikasi potensi risiko permukiman kumuh di Dusun Karang Desa berada pada tingkat kekumuhan ringan dengan penanganan prioritas pada pembangunan dan perbaikan saluran pembuangan limbah, jalan lingkungan dan sistem drainase.
