Abstract

Otomatisasi pengisian bejana ukur dengan sensor water flow dan katup solenoidmenjadi sangat penting dalam industri karena beberapa alasan utama. Otomatisasi meningkatkan efisiensi proses pengisian, menghemat waktu dan tenaga manusia. Selain itu, pengisian otomatis juga menjamin konsistensi dalam jumlah cairan yang diisikan ke setiap bejana ukur, mengurangi kemungkinan kesalahan manusia. Dalam penelitian ini, telah berhasil dirancang sebuah instalasi pengisian bejana ukur otomatis menggunakan sensor YF-S201, katup solenoid, dan Arduino UNO. Pada penelitian ini, besarnya nilai konstanta untuk kalibrasi sensor alir tipe YF-S201 adalah 7,3. Instalasi ini mampu mengisi bejana ukur dengan akurasi dan presisi yang sangat baik. Akurasi rata-rata pembacaan sensor YF-S201 dengan titik uji debit (L/min) sebesar 97,97%. Sedangkan untuk nilai presisi sebesar 98.88%.

Abstract

The Legal Metrology Unit (UML) is a unit that carries out metrological activities in the Regency/City. UML has a vital role in achieving a well-measured market. These metrological activities include calibration and re-calibration and metrological supervision activities. One of UML's efforts to support these activities is to maintain the working standards it has, in this case, reference weights. In addition to purchasing existing measuring instruments with four sensors at once being very expensive, prototyping is the leading choice because it can be developed according to needs. This study created a prototype for monitoring the room conditions of the reference weight storage cabinet. This prototype uses four sensors integrated with a microcontroller to measure temperature simultaneously. The testing process for the prototype began with testing the temperature sensor with a standard thermocouple and water bath. Furthermore, the prototype will be tested with a standard thermohygrometer measuring instrument. The test results of the prototype for accuracy have a range of 94%-98%, precision of 97%-98%, and an error of 2%-4%. Meanwhile, the results of the measurement uncertainty of the prototype for the morning are by the provisions in the range of 0.37 °C-0.46 °C, and in the afternoon, they do not comply with the requirements, namely in the range of 0.38°C-0.61 °C.

Abstract

ABSTRAKPada distribusi air bersih kepada konsumen, tekanan permulaan biasanya dibuat lebih tinggi dan sering berubah pada saat aliran. Kondisi ini dapat mempengaruhi akurasi meter air, meskipun alat ini didesain untuk dapat beroperasi pada rentang tekanan lebar. Oleh karenanya, pada penelitian ini, prototipe instalasi uji dibuat untuk mempelajari pengaruh tekanan air pada akurasi meter air secara bersamaan. Prototipe ini terdiri dari dua pompa yang mampu menghasilkan tekanan air tinggi, sensor tekanan posisi hulu dan hilir, pengatur aliran, sensor aliran, meter air, sensor suhu, dan sebuah sistem akuisisi data nirkabel dengan perhitungan otomatis. Hasil kalibrasi menunjukan bahwa semua sensor memiliki rata-rata akurasi 99,4% dan presisi 99,7%. Hasil pengujian akurasi meter air pada kenaikan tekanan dari 0,5 bar ke 4,5 bar menunjukan nilai kesalahan meter air yang semakin meningkat dari 5,1% menjadi 7,2%, sehingga pada studi ini dapat dilakukan pengujian akurasi meter air pada tekanan air yang lebih tinggi dibandingkan dengan penelitian sebelumnya.Kata kunci: tekanan, akurasi, instalasi uji, perhitungan otomatis ABSTRACTIn the water distribution, the starting pressure is usually made higher and frequently changes during the flow. This condition can affect the accuracy of water meter, though it was designed to be operated at a wider pressure range. Therefore, a prototype of testing installation is assembled to study the effect of the water pressure to the water meter accuracy simultaneously. It consists of two pumps which able to generate high water pressure, pressure sensor (upstream and downstream), flow regulator, flowmeter sensor, water meter, temperature sensor, and wireless data acquisition system with automatic calculation. Calibration results show that all sensors have average accuracy of 99.4% and precision of 99.7%. Water meter accuracy testing results at the increasing pressure from 0,5 bar to 4,5 bar show that water meter error values increase from 5,1% to 7,2%, so this study can perform accuracy test at a higher water pressure as compared to the previous research.Keywords: pressure, accuracy, testing installation, automatic calculation

Abstract

Cooking oil, especially palm oil, is one of the highest commodities produced and consumed by Indonesia. Throughout 2022, Indonesian people consumed 20.9 million tons of palm cooking oil. With the recent emergence of cooking oil dispensers, a regulation, method, or tool is needed to measure the quality of cooking oil stored in cooking oil dispensers. One of the factors that determines the quality of cooking oil is thickness or viscosity. The viscosity or thickness of cooking oil is greatly influenced by the temperature of the palm oil. Therefore, a prototype tool for measuring cooking oil viscosity was created using a laser module and a Light Dependent Resistor (LDR) sensor. This tool is based on a falling ball viscometer, where time recording is assisted by an internal timekeeper on the Arduino Uno. The results of testing the measuring instrument prototype at temperatures of 29 °C to 45 °C showed that the accuracy was more than 95.82% and the precision average is 94.73%. This prototype displays the viscosity measurement results on the I2C 16x2 LCD in Pa.s units and has a push button to hold the measurement result value.

Abstract

Despite increasing recognition of Indigenous knowledge systems, the role of informal adult learning within customary communities remains under-theorized in mainstream adult education discourse. There is limited understanding of how traditional practices, beliefs, and community structures shape learning processes outside formal institutions. This study investigates the role of informal adult learning in Kampung Adat Banceuy, a Sundanese customary village in West Java, Indonesia. The research focuses on how learning is embedded in four interconnected domains: customary leadership, ritual practice, selective acculturation, and community-based tourism. These domains form a cohesive learning ecology through which cultural knowledge, social roles, and ethical values are transmitted and adapted across generations. Using an ethnographic methodology, the study involved participant observation, semi-structured interviews with 36 informants, and analysis of cultural documents. Data were examined through thematic coding and interpretive analysis to capture the nuanced, situated processes of learning as enacted in everyday life. Findings show that informal adult learning in Banceuy is relational, embodied, and performative. Tourism, in particular, functions as a reflexive learning environment where adults develop narrative, logistical, and intercultural competencies while negotiating cultural meaning and ethical boundaries. Rather than being a site of commodification, tourism becomes a space of identity work and adaptive pedagogy. These insights challenge conventional hierarchies of formal education and affirm the centrality of Indigenous learning systems in sustaining cultural resilience. The study offers implications for policy and theory, emphasizing the need to support culturally embedded, community-driven models of adult education.

Abstract

A water meter is a device used to measure the volume of water used by customers and is used as a basis for determining water retribution. The influence of pressure both in the position before (upstream) and after the water meter (downstream), then flow conditions that could be temporal and stable also affect on the accuracy of the water meter. Then, in this study, a prototype of a water meter test equipment was made that was able to vary the pressure in two positions and flow conditions and then determine the error of the test water meter automatically from the weighing process. Prototype scales and sensors (pressure gauge sensors, flow gauge sensors and temperature gauge sensors) have accuracy and precision in the range of 93,4%-99,9% and were connected to smartphones via an Android app that has data acquisition capabilities. The test results showed three downward error trends, namely 6,63%-4,70% (Temporal Flow, Upstream Position Pressure Regulation); 4,41%-3,66% (Temporal Flow, Downstream Position Pressure Regulation) and 3,21%-1,76% (Temporal Flow, Downstream Position Pressure Regulation). The results of the analysis showed that the pressure difference between the upstream position and the downstream position that exceeded 0,63 bar caused the test water meter error to exceed the error limit of ±4%, especially in temporal flow conditions compared to stable flow.
