Abstract

Path planning is an important aspect in robotics, allowing a robot to reach its destination safely and efficiently. The Informed Rapidly-exploring Random Tree Star (Informed RRT*) algorithm has become one of the popular path planning methods due to its efficiency and ability to handle complex workspaces. Since its introduction in 2014, various variants of Informed RRT have been developed to improve its performance. However, there has been no comprehensive study comparing the performance of these variants. This research aims to conduct a comparative study of the performance of several Informed RRT variants in solving path planning problems. The algorithms compared are APF-IRRT, BI-RRT, Informed RRT* + DWA, Informed RRT*-Connect, Informed RRT*-PSO, MI-RRT-Connect, and Informed RRT* with wrapping** procedure. Algorithm performance is evaluated based on computation time and path length metrics. Experiments were conducted on various path planning scenarios with different complexities. The results show that certain Informed RRT variants perform better than others in different metrics. APF-IRRT and Informed RRT-Connect* generally have faster computation time, Informed RRT-PSO* and Informed RRT with wrapping procedure produce smoother paths. This research provides a better understanding of the strengths and weaknesses of Informed RRT variants, enabling the selection of appropriate algorithms for specific path planning applications.

Abstract

Humans in everyday life really need energy. Energy use is expected to be sustainable, safe and clean. Solar is a renewable energy source that sustains life on earth, it can be utilized through photovoltaic and solar thermal systems. Solar thermal systems that capture solar energy can be used directly for water heating purposes. So that an environmentally friendly water heater can be created. This water heater is a solar water heater. Another problem is that the temperature setting for hot water is still manual, causing waiting time and wasted energy when mixing water is not according to your wishes and needs. The solution requires an automatic temperature regulator is needed on a solar water heater. The DS18B20 temperature sensor is used to read the water temperature, the Wemos D1 R2 microcontroller will consider whether the temperature read is appropriate or not according to the user wishes. If it is not suitable, it will instruct the relay to be active and turn on the water pump to circulate water to the heating collector. Setting the desired temperature can be done remotely using Internet of Things technology. From the results of testing the tool, the solar water heater that has been made is capable of providing hot water temperatures of 50.25 °C, 46°C, 43.12 °C when the tank contains 10 liters, 20 liters and 30 liters of water. The set point setting was successfully done using the blynk platform

Abstract

Background: Banyak produk UMKM Indonesia yang sangat layak untuk menjadi komoditas ekspor. Namun data menunjukkan bahwa: 1) rata-rata UMKM Indonesia mempunyai pengetahuan yang terbatas mengenai seluk-beluk persiapan produk untuk tujuan ekspor, 2) jumlah produk UMKM Indonesia yang diekspor masih sedikit. Oleh sebab itu pengabdian kepada masyarakat ini bertujuan untuk mempersiapkan UMKM Indonesia untuk go digital dan memasuki pasar internasional, khususnya Australia. Metode: Pelatihan ini dilaksanakan secara daring selama sebelas minggu berturut-turut pada bulan April – Juli 2021. Selain pelatihan daring, proyek ini juga memberikan pendampingan kepada UMKM dan kurasi produk mereka untuk diekspor. Rata-rata peserta setiap sesi pelatihan daring adalah 200 orang. Selama pelatihan, dilakukan pre dan post test untuk mengukur pemahaman peserta terhadap materi webinar. Hasil: Hasil uji-t pada skor pre dan post test menunjukkan adanya peningkatan dalam pemahaman para peserta terutama perihal bisnis, penciptaan produk untuk ekspor, menciptakan profil perusahaan yang profesional, merancang kemasan yang kreatif, pengetahuan tentang proses ekspor, dan kesadaran akan hak kekayaan intelektual. Kesimpulan: 1) Pelatihan secara online terbukti efektif untuk pembelajaran UMKM, 2) Pendampingan untuk UMKM secara online mampu meningkatkan pengetahuan dan ketrampilan UMKM dalam mempersiapkan produknya untuk ekspor, 3) masih diperlukan pelatihan dan pendampingan berkelanjutan agar UMKM Indonesia semakin siap menghadapi tantangan perdagangan internasional, terutama ekspor.

Abstract

Penerangan jalan berkaitan erat dengan keselamatan dan keamanan masyarakat pengguna jalan pada malam hari. Khususnya jalan-jalan kecil atau jalan setapak yang terletak di pedesaan atau perkampungan pinggir kota, sangat membutuhkan penerangan yang memadai untuk aktifitas masyarakat di malam hari.  Pengabdian Kepada Masyarakat (PKM) di wilayah Pondok Pesantren Salafi Roudhotul Husna yang beralamat di RT/RW. 08/03 Desa Rocek, Kec. Cimanuk, Kab. Pandeglang bertujuan untuk melakukan peremajaan dan pemasangan instalasi Penerangan Jalan Umum (PJU) di area titik-titik gelap di jalan-jalan setapak wilayah tersebut dengan mengunakan kontrol pewaktu otomatis yaitu Timer Theben Sul 181 H. Metode pelaksanaan kegiatan PKM ini terdiri dari beberapa tahapan diantaranya: koordinasi, analisis penentuan titik lokasi pemasangan PJU, perancangan, pengembangan, implementasi, dan evaluasi.  Hasil yang diperoleh dari kegiatan PKM adalah bahwa analisis yang tepat terhadap area titik pemasangan PJU memberikan manfaat secara maksimal penggunaan PJU di malam hari, penggunaan tiang-tiang PJU yang sesuai membuat umur pakai akan lebih lama, penggunaan Timer Theben Sul 181 H pada PJU dapat mengatur padam dan nyalanya lampu-lampu PJU secara otomatis di sekitar wilayah pondok pesantren menjadi lebih efisien sesuai dengan waktu yang ditentukan, sehingga dapat menghemat pemakaian energi listrik. Selanjutnya, pelatihan operasional dan prosedur perawatan pemeliharaan PJU kepada warga sekitar diharapkan mampu menambah pengetahauan warga.

Abstract

Electric energy is important in human life, because almost all activities use electronic devices. Kiosks also have use of electrical energy. Small kiosks that can move around are not suitable for kWh meters (Grid). The solution is to utilize alternative energy in the form of Solar Power Plant, an independent energy producer by converting sunray into electric energy. Before system is built, planning is needed to get a reliable system. Method used to plan this system is R&D (Research & Development). The process includes: relevant studies, site(location) selection, load and energy consumption estimation, system design, component rating calculation, selection of components, design revisions, compiling budget plan, as well as conducting economic calculations. Planning results for a system with a load of 260 Watts and daily energy consumption of 1.1 kWh, system require 3 PV panels of 350 Wp, SCC rating 96V 60A max input with max power of 1440Watt at 24V, inverter 24/220V 50Hz with 1000Watt continuous and 2000Watt maximum power, battery bank with capacity of 300Ah 24V. System is feasible and profitable because it has a payback period (PP) value < PV panel lifetime, as well as an RoI (Return on Investment) percentage value of +11% profit.

Abstract

This paper presents an enhanced study on the design, modeling, and implementation of a Negative Ion Generator (NIG) based on the MQ-135 air-quality sensor and Arduino Nano microcontroller. The research combines theoretical modeling of corona discharge, electric field dynamics, and Cockcroft–Walton (C–W) voltage multiplication with experimental validation. Measured pollutant reductions ranged between 25–40% within 10 minutes of ionization, correlating well with theoretical predictions [1]. The proposed smart NIG offers low-cost, energy-efficient, and automated operation suitable for modern indoor environments, contributing to the development of intelligent IoT-based air-quality systems [2]
