<![CDATA[This research has developed the slice test device to test natural rubber composites made of magnetically modified natural zeolite on nanosilica-reinforced natural rubber composites. We tested the sample similarity with incision cadavers in surgical practice with mechanical characteristics like human tissue. Natural rubber was used as a primary component in the production of synthetic human tissue. The natural rubber was blended with magnetic particle nanosilica, an alternative filler that mixes nanosilica, natural zeolite, and magnetite. This project used several materials formulas to give synthetic human tissue the desired mechanical qualities and incision test characteristics. We used technical specifications rubber (TSR) SIR 20 with nanosilica reinforced fillers and Titanate coupling agent (TCA) as filler and elastomer binders. Samples were characterized using Universal Testing Machine and then tested with the incision test equipment specially designed by the team. Mechanical characteristics of different human body part tissue were compared to the control samples and had similar mechanical characteristics with internal human tissue characteristics. It was found that nanosilica fillers combined with magnetically modified zeolites and titanate coupling agents are potentially applicable for synthetic muscle replacement cadavers with a custom formula.]]>

<![CDATA[The numeracy ability of students in Indonesia is in a low category based on PISA results from 2000 to 2018. So, efforts are needed to strengthen numeracy skills through the development of ethnoscience-based numeracy test instruments. The purpose of this study was to analyze the characteristics of the ethnoscience-based numeracy test instrument using the Rasch model. The subjects of this study were students of SMPN Arun and SMPS Sukma Bangsa, Lhokseumawe City, totaling 123 students. The number of questions to be analyzed in the test is 68 items. Analysis using Winsteps software. The results of the analysis showed that the ethnoscience-based numeration instrument in this study was declared reliable. 59 of the 68 items were said to be valid, with details of 32 valid items eligible to be used and 27 valid items needing to be revised for improvement before being used. This instrument can be used to measure subjects who have ethnoscience-based numeracy skills in the low, medium, and high categories, so to examine ethnoscience-based numeracy skills students can use this instrument.]]>

<![CDATA[This research aimed to assess if MAS Syamsuddhuha's application of the PjBL model has increased the efficiency of the student's training processes. This analysis is a quasi-experimental design analysis. The subjects of this research are students from grades X IPA 4 as the experimental class and X IPA 5 as the control class. During the experiment, the experimental class used the PjBL model with teaching aids, whereas the control class used the PjBL model during the teaching process. The design method used in this study is called nonequivalent control group design. Instrumental research tools in the form of tests and observation sheets are used to observe students' science process skills. The hypothesis uses a non-parametric test for the post-test sample rate. The results showed that the post-test experimental class score was 81.19, and the control class post-test score was 66. Applying the PjBL model with teaching aids has increased students' science process skills in work and energy.]]>

<![CDATA[This study aims to determine the depth of the aquifer layer in the Muara Batu and Dewantara sub-district as a source of groundwater that can be used continuously. The identification of this aquifer layer is based on the results of the resistivity values of subsurface rocks measured using the electrical resistivity method of the Schlumberger array. Data acquisition was carried out on 3 lines (MB1, MB3, and MB4) with a length of 330 m each. The variations in the resistivity values of the rocks obtained were modeled in the form of a 2D cross-section using the Res2DInv software, thus providing an overview of the subsurface for groundwater exploitation. The cross-sectional model obtained shows that the shallow aquifer layer is at a depth of 20-52 m (2-12 Ωm) on the MB1 and a depth of 60 m on MB3 and MB4. The low resistivity value 12 Ωm on the MB1 indicates that the subsurface is generally composed of water-saturated rock layers.]]>

<![CDATA[Pantai wisata Gampoeng Geulumpang Sulu Timue merupakan salah destinasi wisata favorit bagi para wisatawan domestik karena keindahan pantai dan alamnya. Selain sebagai tempat wisata, pantai Gampoeng Geulumpang Sulu Timue juga memiliki tambak garam dan potensi perikanan laut yang cukup melimpah. Masyarakat sekitar pantai Gampoeng Geulumpang Sulu Timue sacara umum memahami bahwa kebersihan lingkungan sangat penting untuk kesehatan, namun kepedulian dalam menjaga kebersihan lingkungan pantai masih sangat rendah. Hal ini disebabkan kurangnya edukasi tentang kebersihan lingkungan pantai sebagai modal meningkatkan potensi wisata yang dapat menguntungkan dari segi ekonomi. Maka dilaksanakan aksi bersih pantai dan edukasi peduli lingkungan di Pantai Wisata Gampoeng Geulumpang Sulu Timue melalui metode edukasi secara langsung, edukasi papan, pembagian peralatan, dan membersihkan lingkungan sebagai langkah awal masyarakat dan wisatawan peduli terhadap lingkungan pantai. Berdasarkan evaluasi, disimpulkan pemberian edukasi dapat meningkatkan pengetahuan, kepedulian dan kesadaran masyarakat Gampoeng Geulumpang Sulu Timue terkait pentingnya menjaga kelestarian dan kebersihan lingkungan pantai wisata.]]>
