    DOI: 10.1088/1757-899X/879/1/012065

    Abstract

    One of the causes of death in humans is lung disease, namely cancer. Data from the Indonesian Cancer Information & Support Center (CISC) shows lung cancer is the number one cancer killer with a total of 14 percent of cancer deaths. The death rate due to lung cancer in Indonesia even reaches 88%. That must be considered to be one of human efforts in maintaining health in the lungs. Handling that can be done is to check early to be able to avoid or treat the lung disease. The existence of an expert system provides a solution to overcome this. Expert system is a computer system that stores knowledge, facts, reasoning and experience from an expert that is used to solve problems in a particular field, especially for lung disease. The purpose of this research is to design an expert system of web-based lung disease diagnosis that can help the public to carry out consultations about lung disease anywhere without having to come directly to the hospital or puskesmas/clinic. The method used is descriptive method and action. In designing the expert system, the method used is the method of object-oriented approach and prototype development method. With this expert system, it will be easier for the public to obtain information about lung disease, help the public and doctors to diagnose lung disease, and help doctors supervise the treatment of patients and the public. © Published under licence by IOP Publishing Ltd.

  • Peristaltic Micro-Pump With Normally Deflecting Membrane Fabricated Using Glass Based Master Mold

    Peristaltic Micro-Pump With Normally Deflecting Membrane Fabricated Using Glass Based Master Mold

    Author: Ayub Subandi ; Jumril Yunas ; Azrul Azlan Hamzah ; Muhamad Ramdzan Buyong

    Abstract

    In this project, a Peristaltic fluid micro pump having normally deflecting membrane on a glass based master mold is developed. The developed peristaltic micro-pumps consists of three or more pump membranes connected sequentially. This structure is primarily aimed for enabling high pumping stroke of fluid hence increasing the flow rate. Besides the main purpose, this method can simplify the fabrication reducing the steps of the membrane transfer from master mold to membrane spacer. In this study, the flexible membrane that forms a curved dome-shaped is fabricated implementing a glass rod as the master mold with diameter and height of 4 mm and 2 mm, respectively. The membrane layer was made by pouring in PDMS at the top of mold master. This technique enables to produce a membrane in a normally deflecting form even though there is no interference with the membrane. Apart from that, the membrane can be adjusted to obtain expected flow rate and certainly the size of the membrane diameter. The structures have been successfully fabricated using soft-lithography technique. The functionality test of the fabricated pump system shows that the fluid was able to flow from the inlet to the outlet on the other side of the pump membrane without leaking. The result of this research is expected to be applied as fluid injection system in biomedical instrumentation that need high fluid rate. © 2020, Universiti Malaysia Perlis. All rights reserved.

  • The Analysis of Fixed Final State Optimal Control in Bilinear System Applied to Bone Marrow by Cell-Cycle Specif

    The Analysis of Fixed Final State Optimal Control in Bilinear System Applied to Bone Marrow by Cell-Cycle Specif

    Author: Rainarli E. ; Dewi K.E.

    DOI: 10.1088/1742-6596/824/1/012029

    Abstract

    The research conducted by Fister & Panetta shown an optimal control model of bone marrow cells against Cell Cycle Specific chemotherapy drugs. The model used was a bilinear system model. Fister & Panetta research has proved existence, uniqueness, and characteristics of optimal control (the chemotherapy effect). However, by using this model, the amount of bone marrow at the final time could achieve less than 50 percent from the amount of bone marrow before given treatment. This could harm patients because the lack of bone marrow cells made the number of leukocytes declining and patients will experience leukemia. This research would examine the optimal control of a bilinear system that applied to fixed final state. It will be used to determine the length of optimal time in administering chemotherapy and kept bone marrow cells on the allowed level at the same time. Before simulation conducted, this paper shows that the system could be controlled by using a theory of Lie Algebra. Afterward, it shows the characteristics of optimal control. Based on the simulation, it indicates that strong chemotherapy drug given in a short time frame is the most optimal condition to keep bone marrow cells spine on the allowed level but still could put playing an effective treatment. It gives preference of the weight of treatment for keeping bone marrow cells. The result of chemotherapy’s effect (u) is not able to reach the maximum value. On the other words, it needs to make adjustments of medicine’s dosage to satisfy the final treatment condition e.g. the number of bone marrow cells should be at the allowed level. © Published under licence by IOP Publishing Ltd.

  • Sustainable Agricultural Land Management in Garut Regency, West Java Province, Indonesia

    Sustainable Agricultural Land Management in Garut Regency, West Java Province, Indonesia

    Authors: Lia Warlina ; Syach Berriant Restu Pradana

    DOI: 10.36909/jer.ASSEEE.16089

    Abstract

    The high land conversion rate to other sectors has led the government to issue Law No. 41 in 2009 concerning Protection of Sustainable Agricultural Land (SAL). The study aims to identify the distribution of sustainable agricultural land uses and determine agricultural land-use changes from 2016 to 2019 and determine farmers’ understanding of sustainable agricultural land control in the strategic area of Garut Regency. We overlaid the land use maps of Garut Regency in 2016 and 2019 and conducted a survey using an online questionnaire with a Google form. The research location is in five districts in Garut Regency. The results showed no land conversion in the area of existing sustainable agricultural land in Garut Regency. The total rice field area is 6,081 hectares, with about 24% is sustainable agricultural land. From 2016 to 2019, the rice field area decreased by 12 hectares. The farmers’ awareness of SAL tends to be more likely aware of the sustainable agricultural land area, as many as 39% of farmers aware of sustainable agricultural land. The incentives given to farmers who control sustainable agricultural land are tax deduction, agricultural infrastructure supply, agricultural production facilities subsidies, and land certification facilities. The majority of the respondents are aware of these incentives. In conclusion, no sustainable agricultural land is converted, even though changes occur in non-sustainable agricultural land. The impact of this study is for recommendations to the government in sustainable agricultural land management. © 2021 University of Kuwait. All rights reserved.

    Authors: Sri Nurhayati ; Riani Lubis

    Abstract

    A health problem that needs to be addressed by national and international authorities is the issue of children’s nutritional status. In Indonesia, this problem needs serious attention from the government and the wider community. This study aims to design a monitoring model for the vulnerability of malnutrition to be used by stakeholders in overcoming malnutrition by reducing the causes. The impact that occurs due to malnutrition in children resulted in stunted growth. Therefore, information is needed to find out what are the causes of malnutrition so that it is easier to solve this problem by suppressing the factors that cause malnutrition. In this study, the method used to determine the causes of malnutrition[ vulnerability was the Topsis method by analysing the factors of malnutrition which include nutritional intake, infectious diseases, childcare patterns, household food availability, sanitation, and poverty. The results of this study were in the form of a monitoring model to determine malnutrition in children so that it can assist stakeholders in overcoming malnutrition by suppressing the factors that cause malnutrition. © 2021 School of Engineering.
