Abstract
Semakin meningkatnya jumlah distribusi produk
hortikultura yang mudah membusuk, semakin meningkat pula
penggunaan kapal kontainer berpendingin (reefer storage). Hal
ini dibutuhkan untuk menjaga suhu buah dan sayuran sesuai
kebutuhan. Di dalam industri cold chain, banyaknya tahap dan
lamanya waktu penyimpanan dan pendistribusian menyebabkan
ketidakstabilan suhu, sehingga perlu adanya monitoring suhu
secara periodik, terutama di dalam reefer storage. Hal ini
dilakukan untuk menjaga kesegaran dan kualitas dari produk. Di
dalam penelitian ini, Wireless Sensor Network (WSN) digunakan
sebagai salah satu inovasi sistem monitoring suhu.
Penelitian ini bertujuan untuk mengadakan percobaan
dan menganalisa efektifitas sistem monitoring suhu menggunakan
Wireless Sensor Network dibandingkan dengan sensor temokopel,
serta mengidentifikasi lokasi sensor suhu di dalam reefer storage
berdasarkan perencanaan peletakan kargo. Penelitian ini
menggunakan pisang sebagai kargo yang harus dijaga suhunya
antara 12 – 16 oC. Percobaan pertama menggunakan sensor
termokopel tipe K dan data logger Labjack T7 Pro. Percobaan
kedua menggunakan beberapa sensor node, koordinator,
repeater, dan modul penerima.
Di dalam sistem WSN diterapkan sebuah topologi star.
Selama 4 jam percobaan dengan interval pengambilan data
selama 2 detik, sistem ini mampu mentransfer 6,446 data suhu.
Selain itu, sensor WSN mampu membaca suhu 12 – 16 oC dengan
eror sebesar 0.68 oC atau 4.7 % dari suhu rata-rata, hal ini
mengacu pada nilai standard error selama proses kalibrasi. Di
lain pihak, sensor termokopel mampu membaca 7,200 data suhu
secara real-time. Sebagai tambahan, lokasi-lokasi kritis di dalam
reefer storage terdapat pada sisi atas dan tengah dari kargo.
Berdasarkan hal-hal tersebut, implementasi Wireless Sensor
Network di dalam reefer storage akan lebih efektif dibandingkan
dengan sensor termokopel dalam hal kemampuan monitoring
secara real-time yang sama serta dalam hal jangkauan transmisi
data dari sensor ke modul penerima yang sejauh 100 meter.
=================================================================
The increasing number of perishable horticultural
product distribution leads to the increasing number of the use of
reefer storage/container vessels. It is needed to keep the
temperature suitable for fruits and vegetables. In the cold chain
industry, some steps and long time needed in the storing and
distribution process cause unstable temperature, so the periodical
temperature monitoring is needed, especially in vessels’ storages.
This is done in order to maintain the freshness and quality of the
products. In this study, a Wireless Sensor Network (WSN) was
implemented as one of the monitoring systems.
This study was aimed to conduct experimentally and
analyze the effectiveness of the temperature monitoring system
using Wireless Sensor Network compared to the thermocouple
sensors, as well as to identify the location of the temperature
sensors in the reefer storage based on the stowage plan. This
study was based on the setting temperature of bananas around 12
– 16 oC. The first experiment used thermocouple sensors type K
and Labjack T7 Pro data logger. The second experiment used
WSN sensor nodes, the coordinator, the repeater, and the receiver
module.
In the WSN system, a star topology was applied. During
experiments conducted for 4 hours with the interval around 2
seconds, this system could transfer 6,446 temperature data.
Furthermore, WSN sensor nodes can read temperature in the
range of 12 – 16 oC with the uncertainty error around 0.68 oC or
4.7 % from the mean temperature according to the standard error
in the calibration process. On the other hand, thermocouple
sensors could read 7,200 temperature data completely and realtime.
In addition, the critical locations in reefer storage were on
the top side and middle side of the cargo. Based on these findings,
the implementation of Wireless Sensor Network in reefer storage
was found to be more effective than thermocouple sensors in
terms of the similar capability to monitor real-time data and of
the range of the data transmission from the sensors to the
receiver which is around 100 meters.
