Investigation of curing silver conductive inks on fabrics using dlp projector and hot plate

This study is to investigate the curing of silver conductive ink tracks on fabrics using a combination of direct light projector (DLP) and hot plate since conventional curing process using laser and oven suffer from several weaknesses mainly costly process and warping defect. The fabrics used are made from nylon and polyester while silver conductive inks were used for the entire study. Samples were made by coating the fabrics with rubber dye inks using silkscreen process and conductive inks were manually laid out on top of the rubber dye according to the designated pattern. A Microsoft power point slide is used to shape the light image on top of the hot plate where the sample is located. Variation of curing time and temperature with constant curing distance were investigated. Several mechanical and electrical tests were conducted to determine the cure, hardness, adhesion and resistance level of the ink tracks. The results obtained were as expected which the longer curing time taken and a higher temperature used, a lower resistance is produced. It is proven that a combination of projector and hot plate is capable of curing the ink tracks properly, a cheap process and easy to handle

Approximating Mexican highways with slime mould

Plasmodium of Physarum polycephalum is a single cell visible by unaided eye. During its foraging behavior the cell spans spatially distributed sources of nutrients with a protoplasmic network. Geometrical structure of the protoplasmic networks allows the plasmodium to optimize transport of nutrients between remote parts of its body. Assuming major Mexican cities are sources of nutrients how much structure of Physarum protoplasmic network correspond to structure of Mexican Federal highway network? To find an answer undertook a series of laboratory experiments with living Physarum polycephalum. We represent geographical locations of major cities by oat flakes, place a piece of plasmodium in Mexico city area, record the plasmodium's foraging behavior and extract topology of nutrient transport networks. Results of our experiments show that the protoplasmic network formed by Physarum is isomorphic, subject to limitations imposed, to a network of principle highways. Ideas and results of the paper may contribute towards future developments in bio-inspired road planning

PENINGKATAN PENGETAHUAN DAN SIKAP SISWA SMK N 2 KOTA JAMBI DALAM KESELAMATAN BERKENDARA (SAFETY RIDING)

Motor vehicle accidents are multifactorial (human factors, vehicles, and the physical environment).The high percentage of young riders in motorcycle accidents is a serious public health problem. The purpose of this counseling activity is to increase knowledge and attitudes in safety riding. The target of this service activity was 21 students of SMK N 2 Jambi City who were selected purposively. Students are given understanding related to safety riding and then followed by a discussion. Before being given the material, students are asked to fill out a pre-test form to measure knowledge and attitudes, then another measurement was taken after the discussion session in the form of a post-test to find out differences in attitude knowledge before and after counseling. Data analysis used the Wilcoxon test and paired sample t-test. The analysis showed that there were differences in knowledge (p-value = 0.005) and attitudes (p-value = 0.001) before and after counseling. Counseling that has a positive impact so that there is an increase in the knowledge and attitudes of students of SMKN 2 Jambi City

Pembatasan HAM dengan Alasan Public Health Emergency dalam Hukum HAM dan Hukum Pidana Indonesia

Konsep “limitation†dapat ditemukan dalam beberapa instrumen hukum hak asasi manusia internasional demikian juga dalam hukum HAM di Indonesia. Konsep ini dapat diterapkan dalam beberapa situasi termasuk dalam keadaan public health emergency. Keadaan saat ini dengan adanya pandemic Covid-19 memaksa negara untuk melakukan pembatasan terhadap hak individu di dalam yurisdiksinya. Hal ini sejalan dengan konsep PHEIC yang beberapa saat lalu diumumkan oleh WHO. Namun demikian bagaimana mekanisme implementasi di lapangan menjadi persoalan lain yang perlu dilakukan penelitian lebih lanjut. Di Indonesia implementasi dari Public Health Emergency of International Concern (PHEIC) adalah limitasi dalam bentuk Pembatasan Sosial Berskala Besar (PSBB) sebagaimana diatur dalam Undang-Undang Karantina kesehatan. Namun demikian, dalam implementasinya di lapangan seringkali PSBB dijadikan sebagai alasan oleh aparat kepolisian untuk dilakukannya mekanisme pidana seperti penahanan terhadap para pelanggar PSBB. Oleh karena itu dalam penelitian ini akan dibahas lebih lanjut tentang apakah Public Health Emergency sebagaimana dikemukakan oleh (World Health Organization) WHO dapat menjadi dasar Pembatasan HAM oleh Pemerintah Indonesia dan apa konsep dan mekanisme yang dapat ditawarkan dalam penerapan pembatasan HAM melalui PSBB ini baik dalam sistem hukum HAM maupun dalam sistem hukum Pidana di Indonesi

KOMPETENSI PEDAGOGIK GURU DALAM PELAKSANAAN KURIKULUM MERDEKA

Seorang guru perlu memiliki kompetensi pedagogik berupa kemampuan mengelola pembelajaran peserta didik yang meliputi perancangan dan pelaksanaan pembelajaran, evaluasi hasil belajar, pengembangan potensi peserta didik dan pemahaman terhadap karakter peserta didik. Maka seorang guru perlu mengetahui apa saja kompetensi pedagogik yang perlu mereka miliki untuk mendukung keberhasilan proses belajar mengajar. Apalagi saat ini sering terjadi pergantian kurikulum yang membuat guru harus menyesuaikan diri dan yang terbaru ialah kurikulum merdeka. SD Ar-Rahman di Kota Cimahi merapakan salah satu sekolah dasar yang telah menerapkan kurikulum merdeka meskipun secara bertahap baru beberapa kelas saja. Peneliti ingin mengetahui seberapa jauh pengetahuan guru di sekolah tersebut mengenai kurikulum merdeka. Penelitian ini bertujuan untuk untuk membahas bagaimana kompetensi pedagogik guru dalam pelaksanaan kurikulum merdeka, apa saja problematika dalam kompetensi pedagogik guru pada pelaksanaan kurikulum merdeka, dan bagaimana upaya meningkatkan kompetensi pedagogik guru pada pelaksanaan kurikulum merdeka. Jenis penelitian ini menggunakan penelitian kualitatif dengan studi kasus. Metode pengumpulan data menggunakan wawancara, observasi dan dokumentasi. Hasil penelitian menunjukkan bahwa kompetensi pedagogik guru dalam pelaksanaan kurikulum merdeka di SD Ar-Rahman sudah cukup baik

Hambatan-hambatan pada Pelaksanaan Pembelajaran Daring di SMA Riyadhul Jannah Jalancagak Subang

In an effort to respond to the Minister of Education and Culture circular number 2 (2020), SMA Riyadhul Jannah is still making every effort to realize learning as mandated by the government during this pandemic by maximizing learning with the e-Learning (Online) model, where all teachers maximize learning by use various types of online applications in an effort to deliver a variety of subjects to students. The school also realized it by changing the schedule of teaching and learning activities; educating COVID-19 to all students; and the use of online learning support media. The problems that were the obstacles that the researchers found in the implementation of learning activities of SMA Riyadhul Jannah were taken from the information of three Islamic Education teachers as research respondents. First, the existence of plagiarism behavior, both plagiarism between students, and plagiarism from the internet. Second, there is an inaccuracy regarding the collection of students' answers in completing assignments. Third, there is an internet network (connection) problem experienced by one of the students due to being in a certain location. So that it resulted in him being unable to take part in online learning
