Abstract

Hipoksia merupakan kondisi di mana terjadi penurunan kadar oksigen di dalam tubuh seorang manusia yang disebabkan oleh beragam faktor khusus. Adapun secara umum penyebab terjadinya pasien yang mengalami hipoksia dapat disebabkan dari berbagai macam gangguan organ tubuh antara lain dengan cara diagnosis medis pada pasien kritis yang mengalami hipoksia antara lain CHF, asma, PPOK, tuberculosis, dan AKI. Secara umum, teknologi sensor untuk mendeteksi hipoksia dapat dilaksanakan melalui beragam metode. Dampak nyata yang terlihat dari seseorang yang mengalami hipoksia dalam periode awal memiliki gejala seperti kelelehan, mengantuk, apatis, kurang mampu memusatkan perhatian. Dalam penelitian ini digunakan beberapa metode yaitu pembuatan sistem minimum, kalibrasi sistem sensor, pengujian sistem dalam ruang, dan pemantauan kualitas udara. Berdasarkan pada hasil penelitian, dapat disimpulkan bahwa sistem minimum yang dirancang pada mikrokontroler Arduino Uno dan sensor oksigen bekerja dengan optimal (stabil 5 dan 12 volt). Sistem sensor telah dikalibrasi dan dapat mengukur konsentrasi gas oksigen di dalam exposure chamber sebesar 20%/vol. Terdapat perbedaan yang kurang signifikan antara konsentrasi oksigen di ruang ber-AC dan ruang tanpa AC. Sumber emisi dan lokasi emisi mempengaruhi level kualitas udara. Konsentrasi gas oksigen di daerah pembakaran sisa limbah pertanian padi berpotensi menurunkan konsentrasi oksigen. Konsentrasi oksigen di kabupaten Lombok Barat kurang dari 20% sedangkan kualitas udara normal memiliki konsentrasi oksigen sebesar 20,9%.

Abstract

The stability of embankment slopes in open-pit mining areas is a crucial factor in ensuring work safety and continuity of mine operations. This study aims to analyze the stability of embankment slopes in the Lube Module area of PT X using the simple Bishop method. The analysis was conducted by modeling the slope geometry and considering soil mechanics parameters, such as cohesion, inner shear angle, and material specific gravity. Simulations were conducted under two main conditions, namely dry conditions and conditions saturated with pore water pressure and seismic loads. The analysis showed that under dry conditions, the factor of safety (FS) of the slope was 2.45, indicating a stable condition. However, under saturated conditions with a pore water pressure of 0.2 and a seismic load of 0.2, the FS decreased to 1.1, indicating a critical condition. This study confirms that pore water pressure and seismic loads have a significant effect on slope stability. Therefore, mitigation in the form of drainage management and optimal slope geometry design is necessary to reduce the risk of landslides.

Abstract

The dynamic nature of estuarine waters necessitates new and accurate methodological approaches for determining salt content or salinity. This can be achieved through direct and real-time measurement of instantaneous and daily EC (Electrical Conductivity) levels in estuaries using EC sensors. On the other hand, similar real-time research has been limited, especially for studies of a continuous real-time nature. Therefore, this study aims to identify the relationship between EC and salinity in an estuary, using the area around the Batulayar estuary, West Lombok Regency, as a case study, employing a direct measurement model continuously for one full day. Measurements were conducted over 5 days during different lunar phases, using direct data acquisition and a numerical linearity approach via data analysis plug-ins. The identification results demonstrate a relationship between EC and salinity. At minimum values, salinity decreases as EC decreases. This reduction follows a quadratic pattern, with an obtained coefficient of determination (R²) of 0.8684 (y = 87397x² – 11173x + 2004.8). This characteristic is also supported by other measured parameters, such as TDS (Total Dissolved Solids), which exhibits a linear relationship with EC. The relationship characteristic between TDS and EC is considerably stronger, as indicated by a linear equation (R² > 0.90).

Abstract

High-quality water resources are important parameters for the sustainability of human civilization, the health of ecosystems, and the advancement of vital sectors. High-quality water is also needed for shrimp cultivation ponds. However, water-quality monitoring in the estuary is limited. In line with this, this study focuses on the design and implementation of an IoT-based TDS and temperature measurement system for estuarine water, aiming to develop an efficient, accurate, and automated prototype to support the fisheries sector in West Lombok regency. This study used a microcontroller, temperature and TDS (total dissolved solids) sensors, a wireless router, and a display. These elements were developed as a water-quality-level monitoring system based on TDS and temperature. The system was calibrated using a standard comparator before being examined under real conditions. The calibration procedure was conducted inside a controlled chamber at a water temperature of 25°C for 60 minutes, with a steady flow rate. All procedures were repeated three times and tested using a Student’s t-test. The IoT platform was tested using RSSI values with a 2s update interval. The calibration data were interpreted as a linear function between the standard and the developed system. The resulting design shows that the developed system can be installed at a shrimp cultivation pond with good performance. The designed system has a linearity of more than 90%. The system has a reliable accuracy level over 30 consecutive measurement days, resulting in the percentages of 85% to 93% (average = 91%). It can be concluded that IoT data communication via a wireless internet router performs well, with RSSI> -50 dBm for both sending and receiving. The IoT platform using ThingSpeak shows good performance (good stability), with a 2-second interval between data updates.

Abstract

Air emissions are a critical issue that can directly impact public health. The larger the emission source, the greater the potential for exposure to the resulting emissions. This problem is also faced by residents (partners) in the Pesona Banyu Asri neighborhood, Banyumulek, West Lombok Regency. Air pollution generated from many directions (four main sources) in the partner area (waste management at the Kebon Kongok landfill, plastic waste processing at BRIDA, waste processing into biofuel, and the pottery production process in the Banyumulek tourist village) is quite high, but the process of quantifying and characterizing emissions has not been implemented/studied in detail. Therefore, the purpose of this community service is to provide alternative solutions that can improve community preparedness regarding air emission disaster mitigation. The implementation method of community service activities is focused on PAR (participatory action research) techniques to improve social aspects of the community. The priority is to identify problems and provide alternative solutions related to the impact of air emission exposure due to emission source activities around the partner area. The IoT (Internet of Things)-based air management system developed by the community service team was previously implemented directly in the community, through stages of observation, socialization, training, installation, and final assessment. The results of the community service process can be seen from the questionnaire data quantification process, where there was a significant increase between before and after the community service activity. The readiness of the partner community increased by 62% regarding the ability to understand air mitigation, both in terms of understanding the types of air emissions, air purification systems, and the operation of the IoT-based air management system that is beneficial for partners.

Abstract

Indonesia is a country with high tectonic activity and frequently experiences earthquakes that can result in significant damage and casualties. One of the earthquake-prone areas is West Lombok Regency, West Nusa Tenggara. To increase disaster awareness and preparedness, an earthquake mitigation outreach program was conducted at SMA Negeri 1 Kuripan. This activity used a participatory–educational approach through interactive presentations, discussions, and the delivery of material using the educational song “Kalau Ada Gempa” from BMKG. The results of the activity show an improvement in students’ understanding and enthusiasm regarding mitigation measures and the importance of preparedness within the school environment. This program is expected to serve as an initial step toward developing a disaster-resilient school in West Lombok.

Abstract

A QCM (Quartz Crystal Microbalance) can be developed as a humidity sensor with a selective coating material. TiO2 (titanium dioxide) is a metal oxide with several crystal phases: anatase and rutile phases. However, there are few studies on the crystal phase investigation of a TiO2-based humidity sensor. Thus, this study aimed to develop a humidity sensor by functionalizing TiO2 particles with different crystal phases. The coating materials were prepared by ultrasonication. The synthesis was conducted by mixing 7 mL of TTIP (Titanium (IV) Isopropoxide) precursor in ethanol. This solution was stirred for 30 minutes, ultrasonicated, and heated for 16 hours to make a gel. The next step was a calcination process with two different temperatures to produce different crystal phases: 500oC (anatase) and 700oC (rutile). The synthesized powders were analyzed using XRD-SEM and coated onto the surfaces of the QCMs used as the developed sensors. These sensors were tested inside a chamber using a humidity control kit and a frequency counter (humidity levels: 57% to 92%). The results show that the rutile phase has a smaller particle diameter (252.672 nm) than the anatase phase (384.589 nm). The humidity sensing examinations indicate that the anatase-phase sensor has faster response-recovery times (19 seconds and 8 seconds) than the rutile-phase sensor (28 seconds and 50 seconds). It can be concluded that TiO2 particles in the anatase and rutile phases can be functionalized as a high-sensitivity coating material for a QCM humidity sensor.

Abstract

One area that requires attention in water quality studies is the estuarine ecosystem. Estuaries are transition zones connecting freshwater and marine waters, thus possessing unique environmental dynamics. However, there is limited information regarding the effect of sea tides in the area on local estuary water quality. Therefore, this study aims to identify the existing relationship between sea tide levels and EC values, using an IoT-based system that is portable, lightweight, and capable of operating in real time. This study was conducted over five days in Senggigi village, Batulayar, West Nusa Tenggara, Indonesia. The collected data focused on the EC parameter's water quality levels at different tide levels, which were monitored using the self-developed system. This system was developed using an EC sensor, a microcontroller, and a wireless internet router (for wireless data communication via ThingSpeak.com). This system was also equipped with a pH sensor, a TDS sensor, and a water temperature sensor. The recorded data show that the resulting data are valid and highly accurate, and that the system is ready for examination at the measurement area. The resulting data show that the correlation between tide level and EC value is logarithmic, with a regression coefficient of 0.934. The EC level was about 20.42 – 62.54 mS/cm, depending on the tide level. It can be concluded that the tide level indeed influences the EC parameter in the estuary area. Moreover, TDS plays an important role in regulating EC levels, underscoring the need to systematically measure this parameter in any estuarine water-quality study.
