The design of the ethanol concentration measurement system using a specific gravity approach has been previously developed. It was built for batch distillation column automation. The measurement system use a combination of 2 kinds of sensor (i.e. load cell sensor and ultrasonic sensor). However, the dynamic characteristic of the measurement system has not been evaluated. This paper is a continuation of the previous paper. This paper aims to describe the dynamic characteristics of the ethanol concentration measurement system. The dynamic characteristic is another performance analysis besides the static characteristic that present in the previous paper. The dynamic characteristic covers rise time, settling time, and overshoot. This paper also presents a transfer function, pole, and zero location by process the output and input data. This paper concern about dynamic characteristics at one-point operation (75 % of ethanol measuring with a hydrometer) then measured by the ethanol measurement system that was designed in this research. Farther the dynamic characteristic was observed from the device until the device reading was steady-state. The result revealed that the rise time of ethanol concentration of measurement system was 56.4 second, settling time 112.2 second and percentage of overshoot was 1.2%. The measurement system can present the actual data after 117.4 second.

Pada awal tahun 2020, telah terjadi suatu pandemi yang melanda dunia termasuk Indonesia. Pandemi ini disebabkan oleh virus jenis baru yaitu Coronavirus (COVID-19). Upaya untuk mencegah penyebaran virus ini adalah dengan menerapkan protokol kesehatan (memakai masker, menjaga jarak, dan selalu membersihkan tangan). Penelitian ini bertujuan untuk merancang dan mengkonstruksi hand sanitizer otomatis untuk mengurangi penyebaran virus COVID-19. Metode penelitian yang digunakan terdiri dari perancangan fungsional dan struktural, analisis biaya serta uji kinerja. Alat ini dirancang menggunakan beberapa sensor yaitu sensor infra merah (IR Proximity), sensor suhu (MLX90614), dan sensor ultrasonik (HC-SR04). Pengujian karakteristik statik dilakukan pada sensor suhu dan sensor ultrasonik. Analisis karakteristik statik pada sensor dilakukan untuk mengevaluasi kinerja sensor. Hasil menunjukan bahwa nilai deviasi sensor ultrasonik adalah 1,16 cm, deviasi sensor suhu adalah 1,07 °C dengan tingkat presisi 0,12 °C serta nilai rata-rata 34,55 °C pada tiap 5 menit pengukuran. Alat ini mampu mengeluarkan cairan pembersih sekitar 0,2 gram/semprotan. Biaya dasar penyediaan semua komponen perangkat adalah Rp.1,500,000 dan total biaya untuk memproduksi setiap unitnya adalah Rp.2,375,000/unit. Perangkat ini beroperasi tanpa perlu disentuh, dan aman untuk diterapkan di area publik. Perangkat juga dibuat dengan sistem pemantauan terintegrasi dimana suhu tubuh yang diukur oleh perangkat ini dapat dimonitor dari jarak jauh, sehingga memudahkan pengguna dalam pencatatan data.

“…There is a linear relationship between SG and density, hence Brix measurement can be done through one of these two quantities [ 4 ]. SG or density can be measured using various methods, such as hydrometer principle [ 5 ], optical methods based on refractive index [ 1 ] or infrared absorbance, near-infrared spectroscopy, X-ray absorption, ultrasonic method [ 6 ], fibre Bragg grating [ 7 ], mass flow of liquid based on Coriolis principle [ 8 ], differential pressure measurement [ 9 ], or biosensing [ 10 ].…”

This paper presents a Brix sensor based on the differential pressure measurement principle. Two piezoresistive silicon pressure sensors were applied to measure the specific gravity of the liquid, which was used to calculate the Brix level. The pressure sensors were mounted inside custom-built water-tight housings connected together by fixed length metallic tubes containing the power and signal cables. Two designs of the sensor were prepared; one for the basic laboratory testing and validation of the proposed system and the other for a fermentation experiment. For lab tests, a sugar solution with different Brix levels was used and readings from the proposed sensor were compared with a commercially available hydrometer called Tilt. During the fermentation experiments, fermentation was carried out in a 1000 L tank over 7 days and data was recorded and analysed. In the lab experiments, a good linear relationship between the sugar content and the corresponding Brix levels was observed. In the fermentation experiment, the sensor performed as expected but some problems such as residue build up were encountered. Overall, the proposed sensing solution carries a great potential for continuous monitoring of the Brix level in liquids. Due to the usage of low-cost pressure sensors and the interface electronics, the cost of the system is considered suitable for large scale deployment at wineries or juice processing industries.
