Published: May 2021

Abstract
The bureaucratic reform policy requires office activities to run effectively and efficiently. This has implications for the transformation from conventional systems to automation systems. The interior arrangement of an office is no longer just the placement of tables and chairs, but requires several important considerations such as the situation and workplace of the employees as well as the necessary technology support. This article aims to provide information on nine objectivity values that can be considered in determining the choice of place and working methods that will be applied before creating an office interior layout. The expected results can help interior designers to be able to determine the space program that suits the types of activities and activities in the office to be designed. In addition, it is hoped that the office designer and manager will have the same goal agenda for designing the office. The results showed that nine objectivity values and six topics of discussion regarding location, users, layout, appearance, archive space, and concept standardization can be supporting points in making an efficient office because it is tailored to the needs of those who work in the office.

Published: May 2021

Abstract
Kendari Bay has been designated as an ecotourism area and as the main route for local trading in Kendari City, Province of Southeast Sulawesi, Indonesia. An earlier study conducted by Armid et al [2] found that water quality in Kendari Bay has been polluted by heavy metals from household and factory wastes. Such metalsare spatially distributed throughout Kendari Bay area, but the main source of contributors to pollutants has not yet been identified clearly. A study on the distribution of heavy metals in the aquatic system of Kendari Bay is imperative to determine the source and status of pollution. This study aims for analyzing the main source of the largest pollutant contributors in Kendari Bay in order to maintain the water quality in this bay. The model for analyzing spatial effect is geographical weighted regression (GWR), and Bayesian Markov Chain Monte Carlo (MCMC) is used to estimate GWR parameters. The data of this study originated from 32 sampling sites spread across the Kendari Bay area, referring to a previous study by Armid et al [2]. Based on these data, numerical simulation results were obtained with prior r = 35 and δ = 10 which produced the best BGWR model with the highest R
2 value of 86.75% and the lowest MSE value of 0.02290; suggesting that 86.75% of the pollutants are caused by heavy metals Pb, Cd, and Cr, while 13.25% is caused by other factors. There are two sampling sites that have significant effects on the number of pollutants in Kendari Bay, both site 3 (downstream of the Wanggu River) and site 29 (Port area).

Published: May 2021

Abstract
Rainfall patterns uncertainty in Southeast Sulawesi-Indonesia is causing many paddy crop failures. There needs to be an adjustment when the appropriate farming time. One of the adaptation efforts in dealing with the influence of climate shift is to establish a planting calendar. Paddy planting calendar is to determine the success of the harvest. The SARIMA model (0,0,0)(0,1,3)12 is the best model for predicting rainfall data. Prediction results show that the highest rainfall occurs in January-July and November-December. Planting time can be done in January-July and November-December by avoiding August, September, and October.
Connection of CTMC process, deterministic and stochastic differential equations in modeling of epidemics
Authors: Sani Asrul , Mukhsar  , Abapihi Bahriddin 
Published: May 2021

Abstract
Mathematical modeling has been used in many fields of study including in epidemiology. The main objective of this study is to show the connection of three mathematical models often used to study the dynamics of disease spread in the natural world; i.e., a stochastic process (CTMC), deterministic model (ODEs) and stochastic differential equation (SDEs). We show that, by proper scaling technique, it is possible to derive the deterministic analogue of a CTMC. Its stochastic differential equation (SDE) version can be obtained by adding a white noise or Weinner process in the deterministic model with proper means and covariance. We demonstrate all three models with the dynamics of SIR epidemics followed by several numerical experiments to show how accurate the trajectories of ODEs follow the sample paths of both CTMC and SDEs.

Published: May 2021

Abstract
Building prices fluctuate greatly each year. Price fluctuations can be on the prices of building materials, human resources, and other cost requirements used in construction. This fluctuation makes it difficult to estimate how much it will cost to build a house in the next year. There are several studies that have discussed budget plan predictions, but few estimate the planned budget for housing development, especially in Indonesia, because it is not yet known how to predict the cost of housing construction in the future, from here it is necessary to conduct research to obtain a formula in predicting development costs housing. The method is calculating the cost modeling using the regression method, the regression method used is Linear Regression. linear regression studies the linear relationship between the dependent variable Y and a single independent variable X. As a result, the formula obtained for the prediction of the cost of housing construction is y = 1,169,813.19 + (334,729,758) X where y is cost is predicted while X is what year with r2 is 0,10.

Published: May 2021

Abstract
This research aimed to explore the roles performed by ICT teachers and conventional ones in the implementation of boating class for coastal students in Pangkep Regency. It is specifically focusing on roles as educators, mentors, managers, and evaluators. The research used descriptive qualitative approach. Two ICT teachers and two conventional ones were taken as the subjects of the research using purposive sampling technique. The results of the research showed that (1) In educating role, both ICT and conventional teachers act as models who possess emphatic feeling towards their students and environment. If the conventional teachers teach students at boat class conventionally using printed modules, the ICT teachers make use of ICT applications such as Whatsapp beside the use of printed modules, (2) In mentoring role, conventional teachers display their patience and loyalty to provide unrestricted knowledge to students inside and outside the classroom whereas ICT teachers provide students with more flexible services using social media applications in discussing the student worksheet and giving feedback, (3) In managerial role, conventional teachers organize the class directly so that the class becomes quiet, convenient, and students do not disturb each other. Differently, ICT teachers manage the class virtually from planning to evaluation. The teaching materials and worksheet are not only given in printed modules but also uploaded online via Whatssapp. and (4) In evaluating role, onventional teachers evaluate the students’ cognitive competence by using printed test. However, ICT teachers make use of technological aids in evaluating students’ competence and skill. The test is made in google form and its link is sent to students so that the students can do it wherever and whenever they are available.
