    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

    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.

    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.

    DOI: 10.15549/jeecar.v9i1.866

    Abstract:

    To boost the development of a regional agricultural sector, a wider scope of superior commodities can be used. It certainly would contribute a lot to regional and national economic sustainability. Therefore, the stakeholders need to formulate an effective and efficient marketing strategy to balance the supply and demand of agricultural products and improve farmers’ welfare. Marketing strategies in each country were differently influenced by several factors ranging from geography, politics, and people’s consumption patterns. This study compares the marketing strategies for leading agricultural commodities in Indonesia and Uzbekistan to obtain a new formula for marketing agricultural products. Uzbekistan is considered one of the countries in Central Asia that has a lot in common with Indonesia, especially in the agricultural sector, and vice versa. This study aims to develop a marketing strategy for enhanced regional commodities and see how significant the economic contribution of the Garut region is on a national scale. The Literature review is used as a research method. We also conducted a case study and field survey in the Garut region, one of the agriculture centers in Indonesia. The results also indicate that a marketing strategy can boost the economy of a specific area. It can be useful for local governments and business entities when developing effective strategies to deal with the national economy and for monitoring of farmer effectiveness. © 2022, Institute of Eastern Europe and Central Asia.

    DOI: –

    Abstract:

    The agricultural sector is one of the influential sectors that contribute significantly to the economy of many Indonesians. Ironically, farmers, as the main actors in this sector,do not yet have good welfare. This condition also occurs in Garut Regency as the most significant contributor to the GDP of West Java Province due to the marketing and management system for horticultural crops has not been integrated. Therefore, mobile-based applications to improve crop management and as a digital marketing media is hoped to increase the competitiveness of superior horticultural products in the Garut district. This research was conducted through a field survey and interview of 30 farmersin the subdistricts of Cigedug and Bayongbong and representatives of employees at the Agriculture Office of Garut Regency. Secondary data in crop production reports, production maps, agricultural machinery, and others were used to support the primary data. Interview results indicate that agricultural production and marketing of horticultural products in Garut Regency are still carried out conventionally. It makes the farmers’ access to various information and markets very limited. Therefore, this study aims to design a mobile-based Marketing Information System and assist plant maintenance and plant marketing in an integrated manner. In addition, a Prototype wasused as the system development method. This study can help farmers market their agricultural commodities and determine the Agriculture Office of Garut Regency policies. © School of Engineering, Taylor’s University.
