“…The government has formulated the Agriculture Infrastructure Fund to ameliorate the financial constraints associated with post-harvest infrastructure ( PIB, 2020l ). However, complimenting this measure with establishment of decentralised cold storage units operating on either solar or biomass energy within rural districts and villages thoroughly deprived of storage facilities (southern and north eastern states) would further reduce food losses, generate employment at the local scale, regulate price volatility and tremendously benefit small-scale farmers ( Mishra et al, 2020 ; Sivaraman 2016 ). On the other hand, encouraging investments and awareness about electricity independent storage options such as evaporative coolers (maintain high relative humidity and lower temperatures as compared to field conditions) can also solve the problem of horticultural losses and storage ( HLPE 2014 ).…”

“…Macam-macam kesalahan yang sering kita lakukan atau lalai dalam memperhatikan penggunaan AC adalah terjadinya penurunan efisiensi, peningkatan konsumsi energi, dan peningkatan biaya perawatan (Trivedi, Bhola, Talegaonkar, Gaur, & Sharma, 2019). Komponen AC harus mendapat perawatan sesuai dengan jadwal yang telah ditenttukan baik mingguan maupun bulanan secara rutin.. Temuan yang ada yaitu banyaknya perawatan yang melebihi tanggal jatuh tempo perawatan, sehingga berdampak pada minimnya perawatan adalah kerusakan AC yang merambat pada satu komponen ke komponen hingga akhirnya AC tidak bisa berfungsi total (Gunawan, Setiawan, & Legirian, 2017;Mishra, Chaulya, Prasad, Mandal, & Banerjee, 2020;Putra & Irawan, 2020).…”

There is no periodic scheduling of Air Conditioner (AC) maintenance, which stems from the lack of recording on the maintenance card and maintenance book, resulting in a lot of AC damage that propagates from one component to component until finally the AC cannot function completely. A system is needed to provide information that will remind the time of maintenance as the first step in optimizing the life of the air conditioner. The purpose of this study is to build an information system of maintenance-reminder, so that the air conditioner used is maintained according to a predetermined schedule. The method used to build this system is a waterfall with five steps, namely: analysis, design, implementation, and testing. To Test the system that has been made, in this study using black box-testing by checking every part of each system. Our findings are to produce a standardized maintenance reminder system. The test results show that all components in the system are functioning properly, so it is easier for users to know which air conditioners need maintenance. With this system, it can maximize the maintenance function to optimize service life.

“…The Raspberry Pi board is interfaced with multi-sensors of MQ3 to determine alcohol contents, LDR to determine the light intensity, and DHT11 to measure the temperature and RH. Mishra et al [35] developed a low-cost solar-powered smart cold storage. They used a modified split air conditioner for cold storage.…”

Cold storage is deemed one of the main elements in food safety management to maintain food quality. The temperature, relative humidity (RH), and air quality in cold storage rooms (CSRs) should be carefully controlled to ensure food quality and safety during cold storage. In addition, the components of CSR are exposed to risks caused by the electric current, high temperature surrounding the compressor of the condensing unit, snow and ice accumulation on the evaporator coils, and refrigerant gas leakage. These parameters affect the stored product quality, and the real-time sending of warnings is very important for early preemptive actionability against the risks that may cause damage to the components of the cold storage rooms. The IoT-based control (IoT-BC) with multipurpose sensors in food technologies presents solutions for postharvest quality management of fruits during cold storage. Therefore, this study aimed to design and evaluate a IoT-BC system to remotely control, risk alert, and monitor the microclimate parameters, i.e., RH, temperature, CO2, C2H4, and light and some operating parameters, i.e., the temperature of the refrigeration compressor, the electrical current, and the energy consumption for a modified CSR (MCSR). In addition, the impacts of the designed IoT-BC system on date fruit quality during cold storage were investigated compared with a traditional CSR (TCSR) as a case study. The results showed that the designed IoT-BC system precisely controlled the MCSR, provided reliable data about the interior microclimate atmosphere, applied electrical current and energy consumption of the MCSR, and sent the necessary alerts in case of an emergency based on real-time data analytics. There was no significant effect of the storage time on the most important quality attributes for stored date fruit in the MCSR compared with the TCSR. As a result, the MCSR maintained high-quality attributes of date fruits during cold storage. Based on the positive impact of the designed IoT-BC system on the MCSR and stored fruit quality, this modification seems quite suitable for remotely managing cold storage facilities.
