Abstract

On this earth, not a few humans have physical deficiencies in the form of five imperfect senses, one of which is blind people. Blind people are someone who is unable to see well because their visual system is impaired due to heredity, accidents, or other factors. In their activities, blind people need assistive devices in the form of a guidepost to find out the appropriate and safe direction of the road. However, it is not common for blind people who still have difficulty walking using manual walking sticks which are considered to have a low level of accuracy. This is then used as the main idea of ​​the research which aims to create an automatic guide in the form of an obstacle detection belt for the visually impaired using a half cylinder method based on a single board microcontroller using solar panel powered. This tool is an innovation of a manual walking stick developed by utilizing the HC-SR04 ultrasonic sensor as an obstacle detector and the Arduino nano control system by applying the half cylinder method to the area of ​​catching the reflected obstruction waves. The reflected waves captured by the HC-SR04 ultrasonic sensor are then converted into distance units to determine the output of the DC motor and buzzer. Keywords — blind people, walking stick, obstacle detection belt.

Abstract

Intisari Pertumbuhan beban kelistrikan di wilayah Ngawi dan Magetan meningkat seiring rencana pemerintah dalam membangun beberapa infrastruktur dan kawasan industri. Penyedia kelistrikan harus mampu memprediksi kemampuan sistem dalam melayani konsumen. Perencanan pembangunan Gardu Induk (GI) memiliki tujuan dalam memastikan persebaran semua beban listrik yang dilayani dapat diakomodasi dengan baik. Penelitian ini menggunakan data historis dalam memprediksi besarnya permintaan kelistrikan di area GI Mantingan tahun 2019 hingga tahun 2026. Metode yang digunakan adalah metode regresi linear dengan perencanaan satu tahap, yaitu periode 8 tahun (jangka panjang). Hasil penelitian merekomendasikan bahwa sistem yang beroperasi saat ini membutuhkan persebaran beban listrik dengan memindahkan tiga penyulang di GI Magetan dan GI Ngawi ke GI Mantingan. Tiga penyulang tersebut yaitu penyulang Walikukun dan Trinil yang mendapatkan sumber dari GI Ngawi dan penyulang Sine yang mendapat sumber dari GI Magetan. Area calon pembangunan GI Mantingan yaitu didaerah Widodaren, Mantingan, Karanganyar, Ngrambe dan Sine. Penelitian menunjukan bahwa GI baru dibangun dengan kapasitas 60 MVA dan besar nilai pembebanan trafo Gardu Induk Mantingan selama 8 tahun memiliki rata-rata sebesar 41,41persen serta biaya pokok penyediaan listik (BPP) rata-rata sebesar Rp. 2.101. Kata kunci kapasitas trafo, konsumsi energi listrik, regresi linear. Abstract The growth of electricity load in Ngawi and Magetan areas has increased due to the government's plan to build several infrastructure and industrial areas. The electricity provider must be able to predict the system's ability to serve consumers. The planning for the construction of substations (GI) is carried out to ensure that all electricity loads served can be properly accommodated. This research uses historical data in predicting the amount of electricity demand in the Mantingan substation area from 2019 to 2026. The method used is a linear regression with one-stage planning, which is for 8 years (long term). The results recommend that the current operating system requires an electric load by moving three feeders in Magetan substation and Ngawi substation to Mantingan substation. The three feeders, namely the Walikukun and Trinil feeders, were sourced from the Ngawi substation and the Sine feeders which were sourced from the Magetan substation. The prospective areas for the construction of the Mantingan Substation are Widodaren, Mantingan, Karanganyar, Ngrambe, and Sine areas. Research shows that a newly built substation with a capacity of 60 MVA and the load value of the Mantingan substation transformer for 8 years has an average of 41.41percent and an average of biaya pokok penyedia listrik (BPP) of Rp. 2,101. Keywords transformer capacity, electrical energy consumption, linear regression.
