Abstract

Saat ini pemerintah Indonesia akan memajukan mutu dan kualitas sumber daya manusia. Salah satu caranya adalah dengan memberikan perhatian khusus terhadap pendidikan di Indonesia. Ujian berstandar nasional merupakan kebijakan pemerintah dalam bidang pendidikan untuk menentukan standar mutu pendidikan. Matematika merupakan salah satu mata pelajaran yang nilai kelulusannya paling sedikit dibandingkan dengan mata pelajaran lainnya. Hal tersebut dibuktikan dengan menurunnya nilai UN matematika di SMK Perdana selama dua tahun terakhir. Menurunnya nilai UN salah satunya disebabkan karena kurangnya pendalaman konsep, berupa uji coba (tryout) yang diberikan oleh pihak sekolah. Padahal mata pelajaran matematika mengharuskan siswa untuk sering berlatih dalam mengerjakan soal.Aplikasi Mobile merupakan salah satu alternatif yang sangat potensial untuk dikembangkan saat ini. Dengan media aplikasi mobile ini di harapkan para siswa mampu melakukan tryout ujian nasional untuk mata pelajaran matematika kapan pun dan dimana pun. Dan aplikasi menyediakan menu pembahasan soal. Sehingga siswa dapat memperdalam serta semakin memahami soal-soal matematika. Hal tersebut akan berdampak pada kesiapan siswa dalam mengerjakan ujian nasional khususnya mata pelajaran matematika.

Abstract

Given the last few years there have been many large earthquakes that have occurred in Indonesia. For example, the Aceh earthquake in 2004, the Yogyakarta earthquake in 2006, the Padang and Bengkulu earthquake in 2007. The earthquake caused a lot of damage to building structures. After conducting an in-depth study on this matter, that the large earthquake that occurred turned out to be due to the acceleration of the bedrock which was greater than the acceleration of the bedrock that had been determined in the SNI 03-1726-2012 earthquake map. Based on these findings, the earthquake map SNI 03-1726-2012 was deemed no longer suitable to be applied as a guideline for earthquake resistant structure planning. Because a new earthquake regulation appeared and was enforced, this resulted in the need for revision or review of existing buildings to be reviewed using the latest regulations. With the existence of the latest regulations (RSNI 03-1726-2019), all buildings planned with the old regulations (SNI 03-1726-2012) need an evaluation of the calculation of the earthquake effect of the old buildings against the latest regulations. Therefore, after conducting research by comparing the structural behavior between the two regulations in the USM psychology faculty lecture building in the T building by comparing SNI 03-1726-2012 with SNI 03-1726-2019, the comparison results obtained in the column of longitudinal reinforcement requirements experienced an increase of 50% and the need for shear reinforcement has increased by 12.04%, while for the comparison of beams the need for longitudinal reinforcement has increased in field reinforcement by 25%, and the shear reinforcement has increased by 25%

Abstract

Professors profession is a profession that is very noble because it carries a very big task that can affect the progress of a nation. The advanced nation must have qualified human resources (HR) that can compete with other countries. In creating quality human resources, the role of education is very important. The role of education according to Law no. 20 of 2003 on the national education system. Performance appraisal is the determination of the operational effectiveness of an organization and its personality based on the target of predetermined strategy, standard and criteria. Lecturer performance appraisal results will produce tremendous results for the study program or faculty, especially determining the decision given rewards or sanctions, other than that the lecturer is motivated to improve its performance. Competence is a statement that describes the appearance of a certain ability unanimously which is a combination of knowledge, skills, and attitudes that can be observed and measured. Whereas with the design of the lecturer performance data management system, performance appraisal will facilitate communication between lecturers and appraisers that are done by simply entering certain data to produce monitoring information routinely and useful. Indicators that assess the main activities of pedagogic competence, personality competence and propesional competence, the value becomes a reference aspect assessed in the lecturer appraisal process. The data used is also taken from student's idenpendensi, so that consistency is maintained.

Abstract

Continuous usage of the lamp because it forgot to turn off resulted in electricity costs becoming more expensive. In this regard, a research will be conducted on a switch system that uses a timer to automatically turn on and turn off the electric current. This switch can turn on and turn off the lights automatically with a predetermined time which is controlled by the Atmega328 microcontroller (Arduino UNO R3 DIP). The Relay Module is used as a trigger to turn on and off the switch and also the DS3231 RTC Module as a timer in seconds, minutes and hours. The purpose of making this tool is expected to be able to control the time of the lights, so that the use of lights can be arranged.
