Abstract

The development of digital technology has had a significant impact on the world of education, particularly in creating more interactive and immersive learning media. One technology that has great potential in supporting the teaching and learning process is Augmented Reality (AR). This Community Service activity is carried out by the Faculty of Engineering and Maritime Technology (FTTK) of Raja Ali Haji Maritime University (UMRAH) at Bintan Private Elementary School in Tanjungpinang City, with the aim of introducing the concept and utilization of AR technology as interactive learning media to teachers and students. The activities include socialization, demonstrations of AR use, as well as discussion and evaluation sessions. The results of the activities show high enthusiasm from the participants, as well as an increased understanding of the use of AR in the context of learning, particularly in the field of shipping that requires the visualization of technical objects. Although there are limitations in infrastructure, this activity successfully encouraged initial initiatives in the integration of innovative technology in the school environment. This event also serves as a means to strengthen the role of UMRAH in supporting the development of local education based on technology

Abstract

Tingginya pertumbuhan penduduk pada suatu wilayah mempunyai dampak yang besar terhadap kebutuhan air bersih. Kebutuhan akan air bersih dari tahun ke tahun semakin meningkat, sedangkan pasokan air baku untuk air bersih semakin rnenurun baik dari segi kualitas maupun segi kuantitas. Pipa distribusi untuk rnengalirkan air dari Instalasi PDAM 3  Ilir ke kecamatan Ilir Timur II Palembang khususnya wilayah pengaliran Bambang Utoyo sampai saat ini belum ada peningkatan atau pemasangan baru. Maka perlu dianalisis sistem jaringan distribusi apakah pipa yang sudah ada dan kapasitas pompa yang tersedia masih dapat menyediakan suplai air bersih untuk wilayah pengaliran Bambang Utoyo. Selain dianalisis perlu adanya analisis altematif sistern distribusi air ke wilayah pengaliran Bambang Utoyo. Dari hasil penelitian total kebutuhan air bersih rata-rata pada wilayah pengaliran Bambang Utoyo adalah 1.777,240 m³/hari.   Ini menandakan bahwa air bersih yang harus disuplai   dari PDAM 3 Ilir perhari harus bisa mencukupi kebutuhan yang diminta. Dari pembacaan meteran pada meteran induk diperoleh rata-rata  debit yang  dialirkan adalah  1.656,685   m³/hari.  Hal  ini menandakan debit yang dialirkan oleh PDAM 3 Ilir belum mencukupi kebutuhan yang ada. Berdasarkan basil simulasi program EPANET 2.0 kapasitas sistem distribusi eksisting yang ada masih belum memenuhi,   Seperti diameter pipa yang belum dimaksimalkan sehingga masih terdapat tekanan yang negatif. Perlu adanya penggantian pipa yaitu pembesaran diameter pada pipa. Agar suplai air untuk wilayah tersebut dapat terpenuhi.

Abstract

The increasing demand for natural and environmentally sustainable cosmetic products has stimulated interest in utilizing mangrove-derived bioactive compounds as alternative ingredients in lip balm formulations. Mangrove species are recognized as rich sources of secondary metabolites, including flavonoids, polyphenols, tannins, terpenoids, and natural lipids, which exhibit antioxidant and protective properties beneficial for lip care applications. This study aimed to systematically evaluate the potential of mangrove species as active ingredients in lip balm formulations by examining their phytochemical characteristics, antioxidant activities, and formulation performance. A Systematic Literature Review approach was employed following the PRISMA framework, involving the collection, screening, and synthesis of relevant studies published between 2020 and 2025. Eighteen eligible primary research articles were included in the final analysis. The results demonstrated that Sonneratia alba, Bruguiera gymnorrhiza, Ceriops tagal, Rhizophora mucronata, and Avicennia marina possess diverse bioactive compounds and promising antioxidant activities, with several species exhibiting very strong antioxidant capacity based on IC₅₀ values. Furthermore, lip balm formulations containing mangrove extracts generally fulfilled cosmetic quality requirements, including appropriate pH, good homogeneity, acceptable melting points, physical stability, and non-irritating properties. These findings highlight the potential of mangrove extracts as multifunctional natural ingredients for developing safe, effective, and sustainable lip balm products, while supporting the value-added utilization of coastal biological resources and promoting future innovation in natural cosmetic formulations.

Abstract

Weaving activities at the Dekranasda Building in the Riau Islands represent a traditional occupation that continues to hold cultural significance. This activity is performed manually using non-mechanized looms, requiring precision, hand-foot coordination, and prolonged sitting. Such conditions may lead to musculoskeletal complaints in the neck, back, shoulders, arms, and legs, affecting workers’ comfort, health, and productivity. This study aims to identify musculoskeletal complaints among weaving artisans and assess the postural risk during yarn setup and weaving activities. A descriptive quantitative approach with observational methods was employed. Data were collected through the Nordic Body Map (NBM) questionnaire to measure body discomfort, photographic documentation of working postures, and postural analysis using the Rapid Entire Body Assessment (REBA) method. NBM results indicated that the most frequently reported discomfort occurred in the wrists, ankles, back, and shoulders. REBA analysis showed a score of 9 for yarn setup and 8 for weaving activities, both classified as high risk, indicating a need for ergonomic interventions. Discussion highlighted that prolonged sitting, repetitive arm movements, and forward-leaning postures increase the risk of musculoskeletal complaints. Ergonomic improvements, such as adjusting table height, seat position, hand reach, and providing work breaks, are recommended to reduce these risks. Future research is suggested to perform detailed anthropometric measurements of the artisans to design more suitable workstations and evaluate the effectiveness of ergonomic improvements in reducing musculoskeletal complaints and REBA scores.

Abstract

The development of an automatic hydroponic system in the Senggarang area, Tanjungpinang began with regional observation and interviews at the Senggarang Village Office to identify existing problems and potentials. The purpose of developing hydroponic plants with automatic water fillers is to reduce public expenditure on buying food, especially vegetable ingredients, and minimize places to grow crops. The method used in the development of hydroponic plants with automatic water filling uses a descriptive method. The implementation of an automatic water filling system using Arduino Uno, relays, water pumps, and ultrasonic sensors has shown satisfactory results. The system works consistently by turning off the pump when the water level reaches 2-3 cm and turning it back on when the water level drops to 11 cm. The test results showed a stable reading with the pump off at a distance of 2.07 cm and on at a range of 11.17-11.63 cm prove that the system can work effectively without manual supervision.

Abstract

Petani Sayur di Desa Gunung Lengkuas masih menggunakan metode penyiraman manual yang kurang efisien dari segi waktu, tenaga, dan penggunaan air. Kegiatan pengabdian masyarakat ini bertujuan untuk mengatasi permasalahan penyiraman manual yang masih dilakukan oleh petani di Desa Gunung Lengkuas melalui implementasi sistem irigasi cerdas. Teknologi yang diperkenalkan adalah sistem penyiraman otomatis berbasis sensor kelembaban tanah dan sprayer yang dikendalikan oleh mikrokontroler NodeMCU ESP8266 serta didukung panel surya sebagai sumber energi. Metode pelaksanaan mencakup observasi lapangan, perancangan alat, instalasi sistem, pelatihan mitra, dan evaluasi kinerja sistem. Kegiatan dilakukan secara tatap muka selama periode September hingga Desember 2024, bekerja sama dengan GAPOKTAN Desa Gunung Lengkuas sebagai mitra utama. Hasil kegiatan menunjukkan sistem mampu mengurangi penggunaan air hingga 30% serta menghemat waktu dan tenaga petani karena penyiraman dilakukan secara otomatis dan tepat waktu. Teknologi ini juga memberikan solusi yang ramah lingkungan dan hemat energi, karena memanfaatkan sumber daya terbarukan. Implementasi sistem irigasi cerdas ini tidak hanya meningkatkan efisiensi dalam pengelolaan pertanian, tetapi juga mendorong transformasi menuju pertanian berbasis teknologi.
