Pengembangan LKPD Berbasis Model Pembelajaran Kooperatif Tipe Think Talk Write Pada Pembelajaran Matematika

Putri Dwi Hardini. 19504114. Development Learning Based of LKPD on the Cooperative Model Think Talk Write Type in Mathematics Learning. Mathematics Department. Faculty of Mathematics, Natural and Earth Sciences. Manado State University. Tondano. 2023. This research is motivated by problems found in learning mathematics which are found from various aspects, one of which is the lack of proper use of Student Worksheets (LKPD). The purpose of this study was to produce Student Worksheets (LKPD) on Triangle material with the Think Talk Write (TTW) type cooperative learning model in class VII SMP Negeri 7 Kotamobagu which is valid, practical and effective. This type of research is research and development (R&D) using the 4-D development model (define, design, develop, and disseminate). The assesment score from the results of the expert validator’s assessment is 95 with a very valid category. For the practicality assessment score seen from the teacher’s response with a score of 98 and for student responses with a score of 87 in the very good category. The develop LKPD meets the effective criteria based on a classical learning completeness percentage of 79%. In conclusion, the developed LKPD is valid, pratical, effective for use in learning

SLOPE STABILITY ANALYSIS IN ANDESITE STONE MINING ROLAS NUSANTARA TAMBANG Ltd. IN PASURUAN REGENCY

In mining activities Rolas Nusantara Tambang Ltd. needs to do a slope stability analysis because at that location there has never been a study on the condition of the slopes. In addition, there are several problems that can cause unstable slopes such as slope geometry that is too upright, the presence of discontinuity fields and mining locations that are close to several active volcanoes in East Java, namely Mount Semeru and Mount Bromo so that the potential for earthquakes and vibrations is high and can be affect the stability of the slopes at that location. This study aims to analyze slope stability using the Janbu method in calculating the factor of safety and the Monte Carlo method for the probability of landslides. From the results of the study, the actual slope safety factor (FK) was 1.703 and the probability of landslide (PK) was 0.000% with a slope height of 12 meters and a slope of 850. Then recommendations were given for the overall slope with an overall height of 36 meters and an overall slope of 570, the factor value was obtained. safety (FK) of 2.170 and probability of landslide (PK) of 0.000%. From these results it can be concluded that the slope conditions are in the safe category.

KAJIAN FRAGMENTASI PEMBERAIAN BATUAN QUARRY ANDESIT DI BUKIT TAPUAN PT. XYZ

PT.XYZ melakukan kegiatan pembongkaran yang terdiri dari peledakan dengan metode tambang terbuka pada batuan andesit (Quarry). Peledakan akan menghasilkan fragmentasi batuan. Ukuran fragmentasi batuan hasil peledakan sangat penting untuk diperhatikan karena dapat menentukan keberhasilan sebuah peledakan. Design geometri peledakan yang kurang tepat akan menghasilkan boulder di atas standar perusahaan, yaitu 60 cm. Boulder yang terjadi harus dihancurkan lagi dalam alat peremuk batuan (crusher), oleh sebab itu boulder diusahakan sekecil mungkin ukurannya. Penelitian ini meredesign geometri peledakan dengan menghasilkan fragmentasi dengan menggunakan metode teoritis Kuz-Ram dan persamaan C.J Konya

Sinergitas Pemerintah Kota Batu Dengan Kelompok Sadar Wisata (Pokdarwis) Oro-Oro Ombo Dalam Mengembangkan Industri Pariwisata (Studi Pada Desa Oro-Oro Ombo Dan Dinas Pariwisata Dan Kebudayaan Kota Batu)

Kerjasama antara Dinas Pariwisata dan Kebudayaan Kota Batu dengan Pokdarwis Oro-Oro Ombo dilatar belakangi atas inisiatif masyarakat lokal yang peduli wisata dan sebagai pelaku pariwisata, dengan tujuan mengembangkan industri pariwisata demi kesejahteraan masyarakat. Namun, kerjasama tersebut belum berjalan secara maksimal karena minimnya komunikasi dan koordinasi antara kedua pihak. Oleh karena itu, penelitian ini bertujuan untuk mengetahui, mendeskripsikan, dan menganalisis sinergitas antara Dinas Pariwisata dan Kebudayaan Kota Batu dengan Pokdarwis Oro-Oro Ombo serta upaya pengembangan yang dilakukan kedua pihak dalam industri pariwisata. Manfaat penelitian ini adalah sebagai bahan masukan untuk pemerintah dan pokdarwis dalam melakukan kerjasama di bidang pariwisata. Penelitian ini menggunakan penelitian deskriptif dengan pendekatan kualitatif. Sumber data yang digunakan adalah data primer dan data sekunder. Teknik pengumpulan data dilakukan dengan observasi, wawancara, dan dokumen. Wawancara dilakukan kepada pemangku kepentingan di dinas maupun di Desa Oro-Oro Ombo. Model analisis data yang digunakan adalah model analisis Miles dan Huberman dengan cara pengumpulan data, kondensasi data, penyajian data, dan penarikan kesimpulan. Hasil dari penelitian ini menunjukkan bahwa adanya sinergi antara Dinas Pariwisata dan Kebudayaan Kota Batu dengan Pokdarwis Oro-Oro Ombo salah satunya melalui kegiatan pembinaan yang diadakan oleh dinas. Adapun bentuk upaya yang dilakukan bersama yaitupemanfaatan lahan kosong di sepanjang Jalur Lingkar Barat (Jalibar) dengan membangun sirkuit motor trail yang dibuka untuk umum. Saran dari penelitian ini yaitu perlu adanya pendekatan dengan saling bertukar informasi agar dapat mengetahui kondisi satu sama lain. Pemerintah harus melakukan pengawasan secara berkala agar pokdarwis merasa di perhatikan oleh pemerintah. Selain itu, pokdarwis juga perlu melaporkan perkembangannya agar pemerintah dapat mengetahui perkembangan pokdarwis. Hal tersebut juga merupakan bentuk tanggungjawab pemerintah terhadap lembaga bentukan masyarakat

Accelerating Sustainable Innovation Towards Society 5.0

The book entitled “Accelerating Sustainable Innovation towards Society 5.0” reviews various efforts to achieve Society 5.0 through the acceleration of sustainable innovation, especially in the fields of science and technology. Society 5.0 is an era of society that is expected to be able to solve various challenges and problems by utilizing various innovations that are adapted to the development of science and technology. Society 5.0 has a vision that is to harmonize the relationship between technology and society. Various forms of sustainable innovation to support the achievement of Society 5.0 are grouped into 3 (three) topics, namely (1) Science and Mathematics for Innovation; (2) Sustainable Food and Agriculture, and (3) Environment and Sustainable Development. The grouping of topics refers to the fields of science and expertise of lecturers at the Faculty of Science and Technology of the Universitas Terbuka, and accommodates 9 (nine) study programs at Faculty of Science and Technology including Information Systems, Mathematics, Statistics, Food Technology, Agribusiness, Biology, Urban Regional Planning, Fisheries Management (S2), and Environmental Studies (S2). This book is expected to provide benefits, insight, and inspire readers more broadly, especially in achieving Society 5.0 through continuous innovation
