Abstract

Date palm (Phoenix dactylifera) is a plant of the Phoenix palms whose fruit tastes sweet and can be consumed by humans. These fruit seeds usually only become a waste and never be utilised by people. The research tries to reduce the waste of date palm by using the date palm fruit seeds to replace the coffee beans. One of the processes of changing date palm fruit seeds to coffee beans is drying the seeds. Instead of using a traditional drying method, this study has designed a prototype of an Internet of Things (IoT) based monitoring system tools inside the drying room that allow humidity and temperature sensors, heater, fan, and mixer to be monitored through a smartphone in real-time. Hence, the monitoring tools inside the drying room could be controlled easily, and the data could be saved as databases in smartphone applications.

Abstract

Advancements in technology necessitate the swift and efficient management of systems, particularly concerning electricity consumption and information dissemination. To address this, a prototype was developed to automate lighting systems and display kiosk information in modern markets. Key components utilized include an RFID reader, GPS module, NodeMCU ESP8266, and relays, all of which played crucial roles in the functioning of the prototype. The primary objective was to create a device capable of automatically controlling the lighting system through relays, triggered by RFID inputs, while also relaying kiosk information via the Telegram application. For instance, when a registered RFID tag is tapped while the shop is open and the lamp is initially on, the lamp will be switched off, ensuring energy efficiency and timely response. The GPS module is employed to obtain location data, which, along with kiosk open/close status, can be conveniently accessed through the Telegram app. This integration of the GPS module enhances the prototype's functionality by providing valuable location-based information, making it easier for users to monitor and access the information remotely. Test results demonstrate that the RFID tag can be read from a maximum distance of 4.5 cm, with an average processing time of 2.47 seconds for lamp switching and 5.6 seconds for accessing information. These performance metrics validate the efficacy of the prototype methodology in achieving its intended goals of automation, energy efficiency, and seamless information dissemination in modern markets.

Abstract

Muscle injuries caused by sports can have a serious impact on sportsmen, to avoid injuries during sports can be prevented by detecting the wrong movement using a strain gauge sensor attached to the muscle which in this study is devoted to the biceps muscle. The strain gauge will detect muscle movement, and the output generated at the strain gauge will be converted into the form of voltage and current which will be used to be processed using machine learning to get data patterns so that they can be grouped into data patterns of wrong movements and correct movements. The strain gauge movement pattern here is simulated using LabView by using a gauge resistance of 120 Ω, strain configuration Quarter Bridge 1, gauge factor 2.05, Vex is the excitation voltage given to the Wheatstone bridge is 5 V and the initial voltage -180.08 µV, the strain gauge output pattern is obtained in the form of Excel and with this data can be converted into voltage and current.

Abstract

This Community Service (PkM) activity aims to address the needs of the congregation of St. Leo Agung Parish, East Jakarta, in enhancing and realizing a sacred and tranquil prayer garden as a means of devotion to Mary, Mother of the Redeemer. Stemming from the church's existing but unrealized master plan, this project faced the primary challenges of a limited land area of 67.20 m², coupled with the necessity to preserve existing trees. Through a collaborative approach, this PkM activity focused on two core areas: prayer garden planning and construction management. In the planning phase, the PkM team developed a prayer garden design embodying the concept of "Simplicity and Naturalness" within a spiritual space that reflects the humble character of Mary, the Praying Mother. This stage encompassed site identification, concept coordination, garden design creation, and the preparation of construction documents. In the construction management domain, the team provided comprehensive guidance, from selecting the implementing contractor and supervising quality and execution timelines, to finalizing construction and inaugurating the prayer garden, an event graced by the presence of the Archbishop of Jakarta, Mgr. Ignatius Suharyo. The outcome of this activity is the realization of the Our Lady of the Redeemer Prayer Garden, which has been inaugurated and blessed by the Archbishop of Jakarta, Mgr. Ignatius Suharyo. This prayer garden now serves as a spiritual space that enriches the faith of the congregation, reflects the simplicity and naturalness of the Virgin Mary, and demonstrates successful collaboration in creating an inspiring space. ABSTRAK Kegiatan Pengabdian kepada Masyarakat (PKM) ini bertujuan untuk merespon kebutuhan umat Paroki Santo Leo Agung, Jakarta Timur, dalam meningkatkan dan mewujudkan sebuah taman doa yang sakral dan menenangkan sebagai sarana devosi kepada Bunda Maria. Berangkat dari masterplan gereja yang telah ada namun belum terealisasi, proyek ini menghadapi tantangan utama berupa keterbatasan luas lahan 67.20 m², serta kebutuhan untuk memelihara pohon eksisting. Melalui pendekatan kolaboratif, kegiatan PkM ini berfokus pada dua bidang utama: perencanaan taman doa dan manajemen konstruksi. Dalam bidang perencanaan, tim PkM menghasilkan desain taman doa dengan konsep "Kesederhanaan dan Kealamian" pada ruang spiritual yang mencerminkan kesederhanaan sosok Bunda Sang Pendoa. Tahap ini melibatkan identifikasi lahan, koordinasi konsep, pembuatan desain taman, dan penyusunan dokumen konstruksi. Di bidang manajemen konstruksi, tim memberikan pendampingan mulai dari pemilihan kontraktor pelaksana, pengawasan kualitas dan waktu pelaksanaan, hingga finalisasi pembangunan dan peresmian taman doa yang dihadiri oleh Uskup Agung Jakarta, Mgr. Ignatius Suharyo. Hasil kegiatan ini adalah terbangunnya Taman Doa Maria Bunda Sang Penebus yang telah diresmikan dan diberkati oleh Uskup Agung Jakarta, Mgr. Ignatius Suharyo. Taman doa ini kini berfungsi sebagai ruang spiritual yang memperkaya iman umat, mencerminkan kesederhanaan dan kealamian Bunda Maria, serta menjadi bukti keberhasilan kolaborasi dalam mewujudkan ruang yang inspiratif.
