Published: March 2024

Covid-19 is a serious respiratory disease that can be fatal for those affected. Governments have tried various strategies to conquer the Covid-19 pandemic. One of them is to vaccinate people with 6 years old and over. The vaccination program aims to form herd immunity so that the number of confirmed positive cases can be reduced. The purpose of this research is to form a mathematical model of the SIR (Susceptible-Infected-Recovery) spread of Covid-19 by considering vaccination factors. The SIR model is combined with a vaccination factor to forestall the unfold of Covid-19. The research method includes deriving models of nonlinear differential equation systems, solving qualitative models, deriving the basic reproduction ratio ( ), analysis of equilibrium points, and building simulation models. This model has an asymptotically stable disease-free equilibrium point. At the same time, the endemic equilibrium point is unstable. Model simulation is obtained by using different parameter values. This is proven through the outcomes of the model analysis vaccination coverage is a key parameter that can be controlled to reduce so that the pandemic ends soon.
A BI-OBJECTIVE COST MINIMIZATION MODEL FOR THE INSULAR TOUR ROUTE PLANNING PROBLEM

Published: March 2024

This article presents a study on the development of a bi-objective cost problem optimization model in planning tourist routes in the island zone. This problem is a new variant of the tour route plan problem. Bi-objective view of two cost components, namely maritime transportation costs and ground transportation costs. Two models were formulated using a mixed integer linear programming approach. The first model was designed to minimize one of the two cost components separately. The second model was bi-objective cost minimization based on the priority weights of the two costs. It was designed to determine minimum transportation costs based on priority weights. Model testing was carried out through numerical experiments on several cases that often occur in industries in Maluku, Indonesia, especially tourism and goods shipping. Each case has variations in the number of islands and nodes. As a result, the model can demonstrate its adaptability to changes in objectives and parameters. For cases that do not have a single solution, an increase in the network structure on the number of islands and nodes will increase the variety of efficient alternative solutions. The set of efficient solutions also shows an inverse relationship between MTC and GTC. The results also show that MTC minimization cannot be used as a reference for TC minimization in cases with many nodes and islands. Efforts to minimize MTC in the island zone impact reducing total costs but do not mean minimizing total costs. In addition, based on the exponential trend line of computing time, the number of nodes has a more significant influence on computing time compared to the number of islands.

Published: March 2024

A properly even harmonious labeling of a graph G with q edges is an injective mapping f from the vertices of graph G to the integers from 0 to 2q-1 such that induces a bijective mapping f* from the edges of G to {0,2,...,2q-2} defined by f*(v_iv_j)=(f(v_i)+f(v_j))(mod2q). A graph that has a properly even harmonious labeling is called a properly even harmonious graph. In this research, we will show the existence of a properly even harmonious labeling of some wheel graph W_n for n is even.

Indigenous Shamanic Worldviews as Eco-cosmologies and Indigenous Knowledge Systems of Sustainability
Authors: Guzy Lidia 
Published: March 2024

Abstract
This article discusses shamanic worldviews theoretically and empirically based on the author’s long-term comparative studies in rural regions of Odisha, India. It deals with local eco-cosmological worldviews expressed in trance traditions, interpreted by the author as expressions of contemporary shamanic worldviews and an indication of ways of transmission of indigenous knowledge. In this sense the comparative examples of shamanic traditions of nag bacca (snake children) and alekh gurumai (ritual specialists) in Odisha are examples of transformative healing through trance rituals based both on concepts of holy craziness and sacred play (baaya/kheelo) and on spirit possession rituals (boil), widely spread in cultures of orality.
In shamanic worldviews, therianthropic transformations of animal human and ecological encounters are transmitted in a rich culture of orality expressed in songs, performances, and trance dances. In this indigenous knowledge transmission, visions and dreams are the most important expressions of shamanic imaginaries, realities, epistemologies, and ontologies, revealing imagined, dreamt, and lived experiences of local shamanic societies. In this way, the visual mental imagery experiences construe the inner and outer knowledge of shamanic life worlds and worldviews.

In the industrial world, it is very important to pay attention to the efficiency of production capacity where the manufacturing lead time for making shoe outsole is influenced by activities that are not value-added (Non Value Added) and activities that are not value-added but necessary (Necessary Non Value Added) in which there is some extravagance that occurs. These activities are in the form of temporary storage in the cooling room and the process of reworking defective products. The method used is Lean Manufacturing, the tools used are Value Stream Mapping (VSM) and Process Activity Mapping (PAM). VSM is used to identify activities that have cycle times exceeding takt time, followed by mapping the Activity Mapping process to analyze activities that are not Value Added. Based on the results of research from 4110 seconds, the process lead time of 3600 seconds is a non-value added activity. The rework process and material storage in the cooling room were identified as having the largest value contributing to lead time, so rework must be eliminated. the percentage of Process Cycle Efficiency (PCE) has increased. The reduction of the finished sheet material process is cooled to the cooling room and the rework process can save about 60 minutes of working time. Saving working hours can increase outsole production capacity so that productivity increases and targets are achieved.Keywords: Lead Time Manufacture, Lean Manufacturing, Value Stream Mapping, Prose Activity Mapping.

Medan City is one of the most densely populated cities in Indonesia. The population that is increasing and densely causes a shortage of land. To meet the land needs, many land uses have been converted. One of the impacts of land use conversion is that there is no environmental balance between development and providing green open space. This study aims to determine the roles and obstacles of the Department of Hygiene and Gardening in managing green open spaces in Medan City. This study used a qualitative approach with descriptive methods describing information about the data obtained from the field in the form of written or oral data from the parties studied. Data were collected based on interviews and documentation. The results of this study can be reviewed based on Hardjanto's theory, there are four points, namely: Equality (equality), Consensus Orientation (mutual agreement), Participation (participation), and Responsivenees (responsivity). Based on the research that has been carried out, it is concluded that the role of the Sanitation and Gardening Service in managing green open spaces in Medan City has three roles. First, the preparation of materials for the implementation of the assessment of park development, reforestation and nurseries. Second, the preparation of materials for the preparation of procedures, standards and criteria for the use and management of fields, green open spaces, recreational parks, sports fields, reforestation, urban forests and nurseries. Third, the preparation of materials for coordinating the needs of park, greening and nursery facilities and infrastructure. Meanwhile, the obstacles experienced consist of two obstac les. First, internal obstacles, namely the lack of land to build new public green open spaces, lack of supervision of the construction of private green open spaces, and the lack of socialization on the importance of planting trees. The second is the external obstacle, namely the lack of community participation in building a park or planting trees around the residence.

ОБРАЗИ-ХАРАКТЕРИ ЗБІРКИ НОВЕЛ Ф. ДУДКА «ДІВЧАТА ОЧАЙДУШНИХ ДНІВ»
Authors: Хомишин Ольга

Мета. У пропонованій статті проаналізовано специфіку творення образів-характерів збірки Федора Дудка «Дівчата очайдушних днів», детермінованість поведінкової моделі персонажного світу ідеєю патріотизму, що пронизує ідейно-тематичний та художньо-образний рівні збірки, а також жанровою специфікою новели, за якої образ-характер розкривається в момент найвищої напруги.
Дослідницька методика окреслюється використанням герменевтичного й інтерпретативного методів, елементів структурного підходу й біографічного методу.
Результати дослідження засвідчують, що ідея національної самости, патріотизму визначає специфіку групування образів-персонажів збірки, своєрідність творення центральних образів-характерів, наснажених пасіонарною енергетикою. Як і належить у творах новелістичного жанру, ці образи розкриваються несподівано, в момент небезпеки. Якщо ж образ героїні не є центральним, то він моделюється значною мірою нюансуванням внутрішнього стану. Можна стверджувати, що значну роль у творенні «психологічного тла», настроєвості новел відіграє біографічний синерген.
