Blind people have limited physical condition. This condition makes the blind use sticks as a guide in their daily activities. With advances in technology, the stick used was replaced with a device used on the wrist by using an ultrasonic sensor and Arduino Promini 328. The ultrasonic sensor works by utilizing ultrasonic waves as transmitters and calculating distances with differences in time difference. Ultrasonic sensor sensitivity from 2 cm to 200 cm. The data processor used was the Arduino Pro Mini 328 microcontroller and the Esp8266 nodemcu with input in the form of sound issued by the Raspberry Pi. Raspberry pi is placed in the user's pocket and connected to the headset to give a warning when the ultrasonic sensor is active. This tool can also detect a distance of 45 cm ahead and 65 cm down.

Abstrac – Lighting installation is very necessary in designing a building. The amount oflight intensity on each room is different depending on the us ability of the room it self. Simple Additive weighting (SAW) method could be used in selecting the right lamp. The greater the value of alternative earn edit the better alternative. Based on this SAW method, it is advisable touse lights that are LED with the highest on value of 9.66, then the TL lamps with a criteria on value of 6.93.

Abstrak: Pandemi Covid-19 telah membawa dampak cukup besar terhadap proses belajar mengajar di Indonesia. Kondisi pandemi mengharuskan sistem pembelajaran beralih dari metode tatap muka menjadi metode online. Berdasarkan kondisi di atas, artikel berikut membahas tentang salah satu teknik pengajaran yang digunakan dalam kelas daring speaking di Politeknik Negeri Padang (PNP), yaitu dengan menggunakan media poster digital. Artikel ini mendeskripsikan pengaruh penerapan media poster digital tersebut dalam pembelajaran daring terhadap kemampuan berbicara siswa di PNP. Partisipan dalam penelitian ini adalah mahasiswa PNP yang mengambil mata kuliah Speaking practice. Penelitian berbentuk deskriptif kuantitatif dan dilakukan dalam 4 tahap yaitu; perencanaan, pelaksanaan, pengamatan dan evaluasi. Dalam perencanaan, bahan ajar dirancang berdasarkan metode poster comment. Rubrik penilaian yang digunakan terdiri dari kelancaran (fluency), akurasi (accuracy), kejelasan (clarity), intonasi (intonation), volume, dan konten (content). Hasil penelitian menunjukkan siswa mengalami peningkatan yang baik untuk semua aspek penilaian. Sehingga dapat disimpulkan bahwa pengaruh dari penerapan media poster dalam proses pembelajaran memberikan dampak positif terhadap kemampuan berbicara siswa dan juga menciptakan atmosfir belajar yang lebih interaktif selama masa pembelajaran daring.Abstract: Covid-19 Pandemic has created a big impact toward educational learning process in Indonesia. Due to that fact, this article discusses about one of the teaching techniques which is used in an online speaking class at Politeknik Negeri Padang (PNP).  This article describes the implementation effect of digital poster media toward the student’s speaking skill at PNP.  The participants of this research are PNP students who take speaking practice subject. The research is a descriptive quantitative study and its done through 4 steps; planning, implementing, observing and evaluating. In planning, the teaching materials are designed based on the poster comment method. The scoring rubric for the speaking assessment consists of fluency, accuracy, clarity, intonation, volume, and content. The results shows that students skill are well raised in all aspects. Thus, it can be concluded that implementation of poster as teaching media gives positive impact to the students’ speaking ability and it creates more interactive learning atmosphere during the online learning hours.

A fire in a building or office is one of the main cases that is currently being serious attention for businessmen and government agencies. Considering there are no activities in an office during nights and holidays, makes the business owners feel uncomfortable leaving the office. To overcome this problem, a sensor is to monitor a situation in the office whether there is a gas leak or a hotspot. It is hope that air pollution and fire monitoring tool can help to prevent fires. The way this tool works uses the Arduino Uno to retrieve data from the gas sensor and flame sensor. The data will be sent to the Ubidots server via NodeMCU ESP8266 as wifi or the internet. The monitoring display can be seen via Android and when there is an emergency, the ubidots server will immediately notify the room owner. The result shows that the effective distance of the sensor is around 10cm to 50 cm and the overall system runs well

Bioinformatics has developed into an application tool for basic and applied research in the biomedical and biotechnology field. Polymerase Chain Reaction (PCR) is a common technique in the molecular area that has always involved bioinformatics science. PCR cloning techniques such as TA cloning and PCR-mediated cloning exhibit complex processes with low success rates. One easy, effective, and practical solution is to use a mega-primer with the Overlap Extension PCR Cloning (OEPC) technique. The success of PCR cloning using the mega-primer design in the OEPC technique is strongly influenced by the characteristics of the mega-primer used. Knowledge of mega-primer characteristics is one of the important factors in the success of PCR cloning. The design process for the mega-primer str promoter was characterized based on the principle of a genetic algorithm using the web-based bioinformatics tools such as ClustalW, NetPrimer, and BLAST. The success of the mega-primer construction in producing recombinant pSB1C3 vector has been confirmed by the sequencing method and the function of the reporting protein (AmilCP). DNA analysis shows a 100 % homologous sequence on the str promoter, while  E. coli colonies successfully express the purplish-blue color. Mega-primer characters can save costs and time of the research by maintaining the primer parameters that provide optimal values and increase the success value of PCR cloning via bioinformatics software. Hence, implications on biological problems, especially using DNA and amino acid sequences, could solve rapidly.
