Development of interactive learning media flip book using Kvisoft flipbook maker based on local culture and art is one way to utilize technology education in the form of software kvisoft flipbook maker which is integrated with local cultural arts and produced a development product in the form of learning media for mathematics flip book. The purpose of this study was to determine the process of developing flip book learning media and the effectiveness of learning media flip book in the learning process in class. The subjects in this study were 30 students consisting of 16 men and 14 women in rade VII junior high school in Indonesia. The development model in this study uses the 4D model which consists of the stages of define, design, develop, and disseminate. The development process in this study starts from the stage define by conducting initial initial analysis, student analysis, taskanalysis, concept analysis, and learning objective specifications; the next stage is the stage design by conducting a benchmark reference test, media selection, format, and initial media design; the next stage is the stage develop by conducting expert validation and development testing; and the last stage is the stage disseminate by packaging media and distributing media in the same school scope with different classes. The development of this learning media flip book can be an alternative choice in the use of mathematics learning media, especially in social arithmetic material.

In the era of the industrial revolution 4.0 and the pandemic era, innovation is needed in thedevelopment of technology-based evaluation tools. One of them is the ispring suite 9. Evaluation tool isimportant because it can help the process of evaluating educators to find out information on theachievement of results during the learning process. In addition to learning outcomes, evaluation can alsodetermine the ability of students to understand concepts. One of them is a two tier multiple choiceevaluation test. Two tier multiple choice is a form of two-tier multiple choice evaluation test. The purposeof this study is to develop a learning evaluation tool that can find out students' understanding of conceptsand can be used online. The research and development model used is 4D. The research instruments usedwere interview sheets, validation sheets, test instruments, and questionnaires. Data analysis techniquesused qualitative and quantitative. The result of this study is a two-tier multiple choice based mathematicsevaluation tool using ispring suite 9 which is seen from: (1) the percentage of validation results frommedia experts is 90.5% and material experts is 96.5%, both of which fall into the very feasible category.(2) the quality of the items seen from the validity obtained 8 valid items with a reliability of 0.815.Judging from the level of difficulty, the percentage is 10% difficult, 80% moderate and 10% easy, thedistinguishing power is obtained 5 questions are included in the good category, 3 questions are quitegood, 1 question is very good, and 1 question is bad, and the effectiveness of the distractor has 9distractors who selected > 5% of all students. (3) The percentage of students 'conceptual understandingafter evaluating two tier multiple choices is 50.5%, which is in the sufficient category, and the results ofthe students' responses are 82% which is included in the very interesting category.

Leptospirosis merupakan zoonosis yang diakibatkan bakteri Leptospira sp. Sumber infeksi pada manusia biasanya akibat kontak secara langsung atau tidak langsung dengan urin hewan yang terinfeksi. Leptospirosis merupakan zoonosis yang paling luas tersebar di seluruh dunia, kecuali daerah kutub. Sejumlah 300.000 sampai 500.000 kasus Leptospirosis berat terjadi setiap tahun. Kabupaten Bantul merupakan daerah dengan kasus terbanyak penyakit Leptospirosis pada tahun 2015-2016 di D.I. Yogyakarta. Pada tahun 2017, kasus terbanyak terjadi pada 6 kecamatan di Kabupaten Bantul yaitu Kecamatan Pundong, Kecamatan Bambanglipuro, Kecamatan Banguntapan, Kecamatan Jetis, Kecamatan Pajangan, dan Kecamatan Sedayu dengan total kasus sebanyak 48 kasus. Dalam pengendalian penyakit Leptospirosis diperlukan suatu informasi yang secara terintegrasi mampu mengolah data spasial dan non spasial secara efektif dan efisien. Salah satu sistem yang dapat menjadi alternatif solusi yaitu Sistem Informasi Geografis. Jenis penelitian ini menggunakan penelitian deskriptif kuantitatif dengan rancangan penelitian studi kasus kontrol. Sampel dalam penelitian ini sebanyak 96 responden terdiri dari 48 responden kasus dan 48 responden kontrol. Metode analisis data dengan analisis spasial, analisis univariat dan analisis bivariat dengan uji Chi Square dengan tingkat kepercayaan 95%. Berdasarkan analisis bivariat menunjukkan bahwa semua variabel bebas mempunyai hubungan dengan variabel terikat yaitu keberadaan tikus di dalam maupun di luar rumah (p = 0,002), keberadaan hewan peliharaan (p = 0,012).
