Pengembangan Media Pembelajaran Matematika Interaktif Berbasis Articulate Storyline untuk Memfasilitasi Kemandirian Belajar Siswa pada Materi Transformasi Geometri Kelas IX SMP/MTs

This research is a development research (R&D) with the aim of producing an interactive mathematics learning media based on Articulate Storyline that meets the valid and practical requirements to assist grade IX students of SMP/MTs in understanding geometry transformation material and facilitating student learning independence. This development research uses the Borg and Gall development model which consists of ten stages, but in this study only reached stage seven, namely: (1) potential and problems; (2) data collection; (3) product design; (4) design validation; (5) design revision; (6) product trial; and (7) product revision. Researchers explore potentials and problems through interviews, observations, questionnaires, and literature studies. Learning media and guidebooks were validated by three validators. The instrument used was a learning media validation questionnaire and a learning media guide book validation questionnaire. The average value of learning media validation is 3.37 with a very valid category and the average value of guide book validation is 3.52 with a very valid category. The learning media was tested on six students of class IX SMP, the instruments used were student response questionnaires and student learning independence questionnaires. The product trial result was 0.96 with a very practical category and very well facilitated student learning independence of 84.33%.

VALIDITAS PERANGKAT PEMBELAJARAN MATEMATIKA DENGAN METODE PENEMUAN TERBIMBING PADA MATERI LINGKARAN KELAS VIII SMP

The purpose of this research is to produce a mathematics learning tool in the form of the lesson plan and student's worksheet using the guided discovery method on the circle material of class VIII junior high school which has been tested valid. This development refers to the Research and Development (R&D) model which includes 10 stages, namely potential and problems, data collection, product design, design validation, design revisions, product trials, design revisions, usage trials, product revisions, and mass production. Modified according to the needs of this research into 6 stages, namely potential and problems, data collection, product design, design validation, design revision, and final product. The data analysis technique used is the descriptive analysis technique. The validation sheet was used as a data collection instrument in this research. The validation sheet is filled out by 3 validators consisting of 2 lecturers of the mathematics education study program FKIP UIR and 1 mathematics teacher. Based on the results of the lesson plan validation, a percentage of 85.6% was obtained with very valid criteria, while the students’ worksheet validation results were 82.6% with fairly valid criteria. This research concludes that mathematics learning tools have been obtained using the guided discovery method in class VII junior high school on the circle material which has been tested valid.

Enabling Automated Sample Delayering, Imaging, and Probing Prep with an Adaptive Endpointing Workflow

The development of advanced logic processing technologies has hit a critical slowing period over the past 10 years. Long gone are the booming days of exponential growth seen in chip transistor density as described by Moore's Law back in 1965.[1] With modern logic manufacturers now capable of creating transistors in the 5-7 nm node range, having the ability to isolate, inspect, and probe individual metal and via layers is of utmost importance for defect inspection and design validation. In this realm of failure analysis, it is critical that design manufacturers possess the ability to isolate any given single layer of their logic samples. These isolated layers can be inspected for defects via SEM, provide validation of CAD designs, or tested with electrical probing for failure analysis. The work here-in describes a functional workflow that enables manufacturers to perform this kind of sample preparation in an automated fashion using the Thermo Scientific™ Helios™ G5 PFIB platform. This workflow can be utilized by both the Thermo Scientific Full Wafer and Small Dual Beam PFIB platforms to streamline sample analysis and failure testing in both the lab and fabrication environments.

Perancangan Spiral Kondensor untuk Pengolahan Sampah Plastik Menjadi Bahan Bakar Minyak dengan Proses Pirolisis

This study aims to determine the dimensions of the spiral groove condenser to convert plastic waste into fuel and determine the material's effectiveness for making spiral groove condensers. This research was conducted in stages: potential identification, data collection, equipment design and calculation, design validation, testing, and equipment feasibility test. In the testing and equipment feasibility test, namely by inserting plastic waste into the pyrolysis process reactor, then heated to a temperature of 180 oC and an evaporation process occurs, the vapors obtained are then condensed to be fuel. The spiral groove condenser design is made with a length of 3 m, a diameter of 30 cm, and a height of 34 cm use ½ inch galvanized iron material and a plate thickness of 0.0127 mm. The cooling water circulation process uses a spiral iron pipe, with a temperature of steam entering the condenser 180 oC and the temperature of the water in the condenser is 40 oC. From 1000 gr of plastic waste can be produced as much as 100 ml of fuel.ABSTRAKPenelitian ini bertujuan untuk mengetahui dimensi kondensor alur spiral untuk merubah sampah plastik menjadi bahan bakar minyak, untuk mengetahui efektifitas bahan pembuatan kondensor alur spiral. Penelitian ini dilakukan dengan tahapan : identifikasi potensi, pengumpulan data, desain peralatan dan perhitungan, validasi desain, pengujian dan uji kelayakan alat. Pada proses pengujian dan uji kelayakan alat yaitu dengan memasukkan sampah plastik kedalam reaktor proses pirolisis, selanjutnya dipanaskan sampai temperatur 180 oC dan terjadi proses penguapan, uap yang yang diperoleh selanjutnya di kondensasi menjadi bahan bakar minyak. Rancangan kondensor alur spiral yang telah dibuat dengan panjang 3 m, berdiameter 30 cm dan tinggi 34 cm menggunakan bahan besi galfanis ½ inch dan tebal plat 0.0127 mm, proses sirkulasi air pendingin menggunakan pipa besi spiral, dengan suhu uap yang masuk ke dalam kondensor 180 oC dan temperatur air pada kondensor 40 oC. dari 1000 gr sampah plastik dapat dihasilkan sebanyak 100 ml bahan bakar minyak.
