Kota Bitung sebagai salah satu kawasan strategis dan pusat perekonomian di Sulawesi Utara, berpotensi terdampak oleh bencana tsunami karena berada di pesisir Laut Maluku yang bisa menjadi lokasi pusat gempabumi besar pemicu tsunami. Untuk mengetahui potensi area terdampak dan waktu tiba tsunami di wilayah Bitung, dilakukan pemodelan penjalaran tsunami dengan skenario gempabumi Mw 7,9 dengan episenter di Laut Maluku menggunakan perangkat lunak TUNAMI-N2 (Tohoku University’s Numerical Analysis Model Investigation of Tsunami No 2). Data yang digunakan berupa parameter skenario gempabumi pembangkit dan data elevasi. Data elevasi terdiri dari data topografi primer hasil pengukuran lapangan menggunakan altimeter digital dan data sekunder berupa data batimetri dari GEBCO (General Bathymetric Chart of The Ocean) dan data topografi daratan SRTM (Shuttle Radar Topographic Mission) dari USGS (United States Geological Survey). Hasil pemodelan menunjukkan bahwa tsunami pertama kali mencapai di wilayah Bitung tepatnya di pantai timur Pulau Lembeh pada detik ke-520 setelah gempabumi. Ketinggian maksimum tsunami bisa mencapai 7,625 meter, sedangkan inundasi terjauh dan potensi area tergenang masing-masing mencapai 750 meter dan 2,1 km2. Lokasi dengan tingkat bahaya tertinggi ada di sebelah barat Pelabuhan Bitung karena topografi yang landai dan berhadapan dengan perairan yang berbentuk teluk sehingga terjadi amplifikasi gelombang. Pantai yang berbentuk teluk ini juga menyebabkan gelombang tertinggi terjadi pada gelombang yang kedua.

The main purpose of this research is to study the microstructure and thermal properties of geopolymers by adding ZnO as a functional composite. Functional composite materials synthesized by alkali activation, using metalempung as the base material and ZnO as aggregate. ZnO was synthesized from ZnSO4 using the precipitation method. The addition of ZnO mass in geopolymer paste was varied from 0.10g; 0.20g; and 0.30g. X-Ray Difraction (XRD) was used to determine the phase formed in functional composite material. The thermal characteristic of the samples was examined by means of Differential Scanning Calorimetry (DSC). The results showed that the composition of ZnO did have a significant effect on changes in microstructure sample. Functional composite materials also had entalphy change and exsoterm peak smaller than sample geopolymer

The COVID-19 virus is one of several viruses that have hit the world so widely and evenly that it has had an impact on the world of education. Under these circumstances, education must continue to be carried out remotely. Education using ICT media and internet networks is one way to overcome distance education. The use of online learning media can make students more independent and experience different experiences when learning through video, audio and text. For physical education it will give more challenge when physical assesment have to carried out for measuring student physical achievement. Balance as physical fitness was the subject of this study that will be measure with a modificated standing stork test. The standing stork test can allegedly be carried out boldly. The homogeneity test obtains a significance value of 0.886 which has a value greater than 0.05, so it can be interpreted that the data distribution is homogeneous or comes from populations that have the same variance. To test the validity using the product moment correlation test, a significance value of 0.001 is obtained which has a value less than 0.05 so that online and offline data can be said to be valid. Because the data is not normally distributed, the parametric test cannot be carried out so that the non-parametric test is bound using the Wilcoxon test for its reliability test. A significance value of 0.112 was obtained for the right leg and 0.223 for the left leg which was greater than 0.05 so that it meant that there was no significant difference between online and offline implementation.

This research aims to investigate the factors leading to siltation in Lake Limboto by analyzing its morphometric characteristics gathered through direct field measurements and remote sensing using Geographic Information System (GIS). Lake Limboto covers an approximate surface area of 26.09 square kilometers, boasts a maximum depth of 4 meters, and maintains an average depth of 2.83 meters. The Shoreline Development Index (SDI) stands at approximately 2.57, indicating an irregular shape of the lake's water body, while the Lake Volume Development (VD) index, at 2.12, suggests a generally flat lake bottom. The Relative Depth (Zr) registers at around 0.69%, as observed from the water turbidity level. The lakebed relief in the vicinity of the lake's periphery is predominantly flat and shallow, particularly in the western, northern, and southern regions, with depths measuring less than 2 meters. In contrast, the lakebed relief in the central and eastern sections tends to be less flat but still features depths of less than 4 meters. Siltation in Lake Limboto primarily results from high sediment input originating from erosion processes, agricultural activities, and settlements in the surrounding area.
