Abstract

One of the critical equipment to support a patient in the hospital would be an infuse system. One of the main problems with the infuse system was manual monitoring. Few researchers try to build a low cost infuse system using a low-cost sensor and microcontroller. This paper proposes a fuzzy Topsis algorithm and Simple Additive Weighting (SAW) algorithm to choose the best sensor for a low cost to the infuse system, which is one of the Multiple Criteria Decision Making (MCDM) problems. Several simulations using three sensors, such as LDR (photoresistor), phototransistor, and photodiode, are performed. By using these two algorithms, it can be shown that the phototransistor emerges as the best sensor with value 1, even though it has the price six times higher from the LDR sensor and three times higher from the photodiode.

Abstract

Disability is a problem with the body-function or body-structure, activity limitations, such as individual's difficulty in carrying out actions in life situations. One example of physical disability is a foot disability or an injury on foot that prevents people’s ability in doing activities, where disabled people will find it hard to move from one place to another. Not only needing assistive devices, disabled people who use wheelchairs also need special facilities to do their activities. One of the activities is to shop. In Indonesia there are still no facilities that make disabled people with wheelchairs to shop at supermarkets in ease. Therefore, an innovation is indeed needed to make an integrated, automated, and special trolleys so it can facilitate and increase awareness of the importance of special facilities for disabled people in Indonesia. The EFD (Ergonomic Function Deployment) method is used to design the trolley according to the respondent's wishes. EFD is a development of QFD by adding a new relationship between consumer needs and the ergonomic aspects of the product. The product attributes that is used are derived from the ergonomics aspect which is known as ENASE (Effective, Comfortable, Safe, Healthy and Efficient). The prioritized variables of product design are trolleys for disabled people that run automatically, have an additional trolley basket (opening an additional trolley), have a soft back and seat, and have a strong locking system so that it makes it easier for users with a weight of 0.06048. The priority of consumer needs (Customer Needs) from the results of the HOE design are 3,4,7,8,9.10,11,14,5,6,12,13,16,18,19,1,15,2, and 17 and the Priority of Technical Requirements from the results of the HOE design are C, A, B, E and D

Abstract

Urban farming (gardening in the middle of the city) is increasingly in demand by modern society. Urban farming provides business opportunities as well as being a lifestyle trend. One of the plants that can be cultivated at home is oyster mushroom. Oyster mushroom cultivation is quite easy but requires a special environment to grow up. To do mushroom cultivation at home, it is necessary to manage temperature and humidity to achieve optimal temperature and humidity. A temperature and humidity control system that can be monitored and controlled through the smartphoneis the result of the study. Temperature and humidity detected by the DHT22 sensor, then read by NodeMCU and sent to the Blynk application via a WiFi connection are considered as the input system. WiFi used by NodeMCU is the same as WiFi used by smartphones. Blynk on a smartphone will display the temperature and humidity read by NodeMCU. If the temperature and humidity are out of the optimal temperature and humidity range for oyster mushrooms, a notification will appear on the smartphone. Temperature and humidity control can be done by pressing the ON / OFF button on Blynk to turn on and turn off the lights or the fan as needed, so that the temperature and humidity return to optimal. Based on testing, the system successfully displays temperature and humidity on a smartphone, displays notifications and makes control. The relative error of the temperature measurement is 2.6% and the relative error of the humidity measurement is 3.2%.

Abstract

In Indonesia, urban area internet users, between villages and cities, are arranged in the villages according to 72.41%, 49.5%, and 48.3%. Following are the composition of internet users in Indonesia: Java, Sumatra, Kalimantan, Sulawesi, Bali-Nusa Tenggara, and Maluku-Papua respectively 58.1%, 19%, 8%, 6.7%, 5.6%, and 2.5%. To overcome this problem, several attempts have been made to equalize internet access in Indonesia, and one of the efforts offered is Project Loon. Project Loon is a communication technology based on High Altitude Platform (HAPs). Research related to Project Loon feasibility testing is conducted using library study methods using SWOT analysis using strengths, weaknesses, advantages, and battles against Project Loon using various indicators such as systems, infrastructure, economy and regulation. The conclusion of this research is that Loon Project has the potential to be implemented not yet available in Indonesia. In terms of infrastructure and economy, Project Loon is quite effective and economical. However, it must still consider the population in the area to avoid operational costs.
