Abstract

Makassar City is the fourth-largest city in Indonesia and the largest in Eastern Indonesia with an area of 175.77 square km and a population of ±1.5 people in 2019, divided into 15 districts and 143 sub-districts. Uneven population density in each sub-district has an impact on the emergence of social problems in society such as: unhealthy environment, chaotic building management, population registration information that is not updated. To overcome this problem, it is necessary to have population info graphics that show the population, age of the population, education, etc. With info graphic data on the population of Makassar city that can be accessed online, people looking for data can use it as a reference. To achieve the objectives of this research, the K-means algorithm method is used to divide observations into K clusters where each observation is a member of the cluster with the closest average value, through an iterative process until the grouping converges. The K-means algorithm can be used on population data. For example, the grouping of population data is divided into three clusters, namely (cluster 1) dense, (cluster 2) medium and (cluster 3) not dense. The results obtained show that five districts: Mariso, Mamajang, Makassar, Bontoala and Tallo are the districts with the densest populations.

Abstract

Kebutuhan energi dari tahun ke tahun semakin meningkat seiring dengan berkembangnya teknologi dan industri. Hanya saja, saat ini energi yang digunakan sebanyak 80% masih menggunakan energi konvensional yang tidak dapat diperbaharui dan tidak ramah lingkungan. Jika tidak ditangani, kemungkinan akan terjadi krisis energi. Inovasi energi alternatif dari sumber terbarukan sangatlah diperlukan, untuk memenuhi kebutuhan energi salah satunya adalah Pembangkit Listrik Tenaga Surya (PLTS). Energi dari sinar matahari dapat dimanfaatkan sebagai energi pembangkit listrik. Hal ini dilakukan ketika matahari menyinari panel surya, cahaya ini kemudian akan diserap. Bagian di panel surya yang menyerap energi matahari ini adalah photovoltaic atau PV. Efek ini kemudian akan menciptakan muatan listrik. Di kawasan kota berpotensi besar dikembangkannya Pembangkit Listrik Tenaga Surya dengan sistem hybrid yang diaplikasikan di atap bangunan. Dengan menggunakan teknik pengumpulan data berupa metode wawancara dan observasi serta pengukuran yang selanjutnya diperhitungkan dengan rumus, menggunakan software simulasi untuk mendesain sistem PLTS menggunakan PVsyst, memperoleh Detail Engineering Design (DED) dan software Homer Pro yang akan digunakan untuk mengetahui estimasi biaya produksi energi listrik yang dihasilkan.

Abstract

— The number of motorized vehicles in Indonesia is increasing rapidly every year. Based on data from the Central Statistics Agency (BPS) in 2017, the number of motorized vehicles with Passenger Car vehicles reached 15,493,068 units. The number has increased compared to 2016 amounted to 14,580,666 units. The increase as the number of motorized vehicles has an impact of the availability of parking lots in a number of locations. Every driver who will park the vehicle wants to get the location / lot of the parking lot as soon as possible. However, the unavailability of parking capacity information in a parking area causes the user to go around first to get an unload parking space, if the parking lot is full, the user even has to go back out because he did not get a parking space. This study designed and built an ESP8266 microcontroller and PING ultrasonic sensor provided information about the availability of parking lots were still unoccupied in this monitoring system. It is hoped can improve the efficiency of parking users who are looking for vacant parking lots and make it easier for parking admins in parking monitoring management. The results showed that the monitoring system that was built could provide information about the availability of empty parking lots and integrated databases to store vehicle owner information based on parking cards. Parking lot information is included on the parking card given to users entering the parking area.
