This analysis technique consists of reviewing the reorder point, safety stock, and total annual inventory cost. The results show that by using the EOQ method, the company can find out how many times raw materials are purchased and in the quantity how many times raw material purchases are made, know how much minimum stock is needed to be on guard, determine the time to reorder raw materials, and know the cost. The results showed that by using the EOQ method the company could generate more optimal profits compared to conventional methods. Furthermore, the research results also show that with the application of EOQ, companies can make savings on raw material inventory costs, namely in 2018 amounting to IDR 19.092.034 and in 2019 of IDR 21.053.480. In the end, this research is expected to provide insights for companies to use the EOQ method sustainably so that the process of planning and controlling raw materials is better.

ОПЫТ ВЫДЕЛЕНИЯ ЛЮТЕОЛИНА ИЗ ТРАВЫ ORIGANUM VULGARE

Due to economic conditions, today the purchase of reference materials from abroad is expensive, and domestic production is low and also expensive. The purpose of this study is to develop a method for isolating luteolin from Origanum vulgare (oregano). The raw material for this work was a sample of oregano herb, collected in 2022 in the Perm krai. The herb extract was obtained with 60% ethyl alcohol. The extract is a dark greenish-brown crystalline powder with a specific aromatic odor. Chloroform and hexane were used to purify the dry extract from nonpolar compounds. Diethyl ether was used to extract luteolin. This choice was justified by the fact that chloroform and hexane well remove non-polar, lipophilic compounds contained in the dry extract, and methoxylated aglycone flavonoids can also dissolve in chloroform. Diethyl ether was chosen because only aglycone flavonoids are soluble in it. Separated using a solvent system, butanol – acetic acid – water (4:1:2). The equipment used was a chromatographic column with a diameter of 10 mm, a vacuum pump. In the course of the study, we proposed the following scheme for the separation of substances, divided into 3 stages: 1st stage is purification of dry extract from non-polar (lipophilic) compounds; 2nd stage is extraction of aglycone flavonoid (luteolin) into diethyl ether; 3rd stage is separation of substances that passed into diethyl ether on a chromatographic column. According to the quality control of the progress of work, namely TLC and NMR spectroscopy, one can note the likely suitability of the developed method for the isolation of luteolin from the extract of oregano herb.

Android Application for Automatic Door Control System using Body Temperature Measuring Sensor

One way for people to prevent the transmission of Covid-19 in indoor and outdoor activities is by using body temperature detection. People who have a body temperature higher than the measurement limit are prohibited from mingling with other people because they have a high probability of being infected with the virus and can transmit it to other people. Manual checks in public places can cause officers to potentially contract the virus and can spread it to other visitors more quickly. Therefore, it is necessary to develop an automatic body temperature measurement system by displaying the results of the measurements on a screen and automatic door as a further prevention step, and temperature data can be stored in a database to help make the right decisions in preventing the spread of Covid-19 in that place. The implementation stages of the activities include: Data Collection, Preparation of Technology Design and Purchase of Materials, Product Manufacturing, Product Testing, Product Evaluation. An Android application for an automatic door control system using a body temperature measurement sensor can be developed into an even better tool. The development of this prototype will be developed by adding a PIR sensor and system modifications. The addition of a PIR sensor is used to increase the security of the tool to detect only human body temperature which can be recorded in order to minimize data errors. The system modifications made can be used for initial examination assessments with body temperature and also the addition of a system for measuring body weight and height to complete the assessment data.

A Comprehensive Strategic-Tactical Multi-Objective Sustainable Supply Chain Model with Human Resources Considerations

This study proposes a multi-objective Sustainable Supply Chain Network (SSCN) model considering human resources limitations with different levels of expertise. The proposed model includes multiple suppliers, factories, and customers, where the construction of factories is a strategic decision, and determining the amount of production and allocating human resources with different levels of expertise is taken as a tactical decision. Also, the capital recovery factor has been used in the mathematical model to prevent the influence of strategic decisions on tactical decisions. The results from the mathematical models of epsilon limit, Non-dominated Sorting Genetic Algorithm II (NSGA II), and Multi-Objective Particle Swarm Optimization (MOPSO) show that by reducing the amount of shortage, the amount of production has increased, and as a result, the costs of production, supply and distribution and transportation have increased. Also, with the increase in the production and transportation of products, greenhouse gas emissions have also increased. Examining the impact of the uncertainty rate on the Robust Fuzzy Optimization (RFO) model also shows that with the increase of this coefficient, due to the increase in the demand in the network, the total costs of production, distribution, purchase of raw materials, and transportation have increased. Examining different comparison indices between solution methods also shows that heuristic methods have higher efficiency than exact methods. MOPSO is more efficient than NSGA II for the designed mathematical model in these investigations.

Factors Constraining Purchasing of Teaching and Learning Materials in Public Primary Schools in Dar Es Salaam-Tanzania

Despite the importance for enhancing teaching and learning materials in public schools, its vital role has been limited by number of constraints. This study explores factors constraints the purchases of teaching and learning materials. Specifically, it ascertained the availability, constraints and consequences of teaching and learning materials in public primary schools in Dar es Salaam-Ilala, Tanzania. A qualitative case study design was adopted and data were collected using in-depth interviews, open-ended questionnaire, Focus Group Discussion (FGD) and documentary review based on the judgmental sample size of 56 respondents. Thematic data analysis strategy was adopted and data were analyzed using MAXQDA 20 software after being obtained through the use of content analysis. Findings showed that printing such as computers, textbooks and printing papers as well as non-printing materials such as library, mathematics kits and chalkboard are the main materials used in primary schools. Also, the study identified constraints for their availability which include lack of fund, lack of budget allocation, poor procurement planning, inadequate government support, high cost learning materials, and poor equity of materials distribution and supply. Then, the consequences of the constraints led to poor students’ performance, lack of confidence among the teachers and students, lack of motivation among the teachers and students, poor schools’ attendance, reduced competence, poor coverage of curricula or topic, difficult in classroom management as well as increases teaching loads to the teachers. We recommend that, in order to improve purchases of teaching and learning materials, the government update its procurement planning, reviewing the policy and distribution strategies of educational materials, allocation of sufficient budget, investment and raise awareness on the progress of educational facilities by installing current technology instruments as well as development of infrastructures in public primary schools. Therefore, quality of education will be improved after adhering to the stated recommendations.

Therefore the EOQ method is very important to be applied in companies in order to achieve more optimal company profits.

Analysis of the Impact of Government-Supplied Material Purchase Contracts with On-site Installation on Construction Market

The purchase contract for government-supplied materials, which means materials provided by the owner in public construction works, has various delivery conditions. Controversy has continued between public agencies such as the Public Procurement Service and construction contractors over the appropriateness of application of the purchase contract with on-site installation conditions, and the Anti-Corruption and Civil Rights Commission (ACRC) made recommendations in 2012. Nevertheless, public agencies continue to actively apply product purchase contracts with on-site installation conditions. In this study, total on-site installation related costs was defined as the sum of direct labor costs, equipment expenses, and other related interlocking costs. As a result of analyzing the total on-site installation related costs of government-supplied materials from the actual construction cost data of 25 construction works, it accounted for an average of 4.49% of the estimated price. If the ratio of 4.49% to the 37.5 trillion won estimated as the average amount of public construction projects in Korea is reflected, the annual on-site installation related costs is about 1.6838 trillion won. It can be confirmed that the proportion of on-site installation related costs of government-supplied materials in the construction market is substantially significant.

SISTEM INFORMASI CUSTOMER RELATIONSHIP MANAGEMENT PADA RESTORAN DI KOTA MATARAM

Internet technology has a significant impact, especially for online restaurant businesses that require a restaurant management information system, known as CRM (Customer Relationship Management) system. The case study used in developing the CRM system for Valia's Kitchen. Valia's Kitchen is an online restaurant business that has been operating in the culinary industry since 2019, located in the city of Mataram. Valia's Kitchen has partnered with a ride-hailing company and provides its own application. However, there are limitations and shortcomings in the operational management provided, such as the inability to display customer data such as names and contact numbers due to privacy and security concerns, the inability to back up all order data, lack of inventory management for products and raw materials, and the absence of a cash flow record for expenditure and income over a specific period, leading to limitations in operational management features. To address these issues, the researchers designed a CRM Information System for Restaurants in the city of Mataram to improve operational efficiency and facilitate transactions with customers. The system is web-based, built using PHP programming language with a MySQL database, following the Personal Extreme Programming (PXP) development methodology, and tested using black box testing approach. The implementation of CRM in the system is manifested in features such as customer data management, menu management, raw material management, promotions management, partner management, raw material purchasing, restaurant expenses management, cash flow recording, transaction reports, restaurant statistics, and detailed reviews. The Black Box Testing results showed that the system features were functioning well without any errors. Furthermore, the User Acceptance Testing (UAT) results indicated that the average assessment scores for three admin respondents were 82%, while the average assessment scores for eleven respondents on the customer side were 86%.

Potentials of Building Information Modelling (BIM) in Managing Variations

As property development and information technologies are going rapid in these few decades, information construction becomes necessarily as a management tool. Changes and variations in construction projects are common and inevitable. This paper aims to study potentials of Building Information Modelling (BIM) in managing variations. The research objective is to identify the potentials of BIM in managing variations. Qualitative method was adopted for this research. Semi-structured interviews were conducted with the respondents to collect data. Twelve respondents were chosen based on the following criteria: (a) involved in BIM projects and (b) experts with BIM knowledge. The respondents involved in the interviews are BIM software providers, BIM software resellers, BIM consultants, main contractors and government personnel in Malaysia. From the interview findings, the potentials of BIM in managing variations are to reduce the variations due to design-related changes, material-related changes, information discrepancies and construction method. Resolving design-related changes includes better visualisation, design coordination, clash detection, better decision making and minimised uncertainties. Managing material-related changes involves automated quantity taking-off, detailed plan for visualisation and material purchase plan. Reducing information discrepancies involves data digitalisation, communication and collaboration, real-time tracking changes as well as improved on request for information (RFI) process. Minimising variations due to construction method includes simulation, better site management and prefabrication with BIM. This research proves that it is necessary to promote BIM management approach in managing variations.

Recommendations for cradle-to-gate environmental product declarations (EPD) in ‘Buy Clean’ procurement based on CDOT’s experience

The use of environmental product declarations (EPDs) in procurement of construction materials has been of increasing interest to government agencies, and adoption in the United States has been driven in part by ‘Buy Clean’ legislation. Buy Clean encompasses green procurement policies that promote the purchase of construction materials and products with lower environmental impacts, considering the life-cycle impacts associated with those materials. Most EPDs for transportation infrastructure construction materials are ‘cradle-to-gate’, or representative of the material production stage of a product and not the entire life cycle; however, these EPDs can allow meaningful quantitative comparisons of environmental and sustainability indicators and serve as a mechanism for measuring improvements in environmental impacts during the production of materials. This paper describes how cradle-to-gate EPDs are used, presents a case study of initial implementation of an EPD policy by the Colorado Department of Transportation, and provides recommendations to address some of the challenges that agencies and stakeholders can face when developing or participating in new EPD programs. It is desired that the recommendations and case study presented in this paper will help provide pathways to agencies for the successful enactment of Buy Clean policies and enable mitigation of actual or perceived barriers to program implementation.

МЕХАНІЗМИ РОЗВИТКУ ЖИТЛОВОГО БУДІВНИЦТВА

The article describes the essence, content and functions of the mechanisms for the revival of housing construction in Ukraine. Its development and implementation envisages the revival of the country, the multifaceted socio-economic development of settlements, the improvement of the demographic situation, and the appeal to man as the main source of the nation's wealth. It has been proven that all European countries have gone through a long process of reforming and developing the construction industry, applying new investment technologies and stimulating the development of this direction of the economy, combining state support, the mortgage lending mechanism and other types of construction support. In the economy of our country, many variants of management mechanisms are used - economic, ecological, market, social, organizational, organizational-economic and others. After the full-scale invasion, almost all developers stopped construction, some for several weeks, some did not continue construction at all. It was determined that in 2022 the total area of ready-made apartments amounted to 7.1 million square meters. m (18.3 thousand private houses and 74.3 thousand apartments), which is 38% less than in 2021. It has been proven that in Ukraine it is not enough to stimulate the development of the construction industry at the state level, it is important to create conditions for the development of a competitive environment, to introduce effective financial and credit mechanisms for the purchase of construction materials. The construction industry should be based on trust in the banking sector of the economy and stimulate the development of affordable rental housing for the low-income population and internally displaced persons. We believe that the housing market in Ukraine is currently in a recovery phase. The prospect of its development requires the creation of an effective organizational and economic mechanism, as well as the implementation of state support for the provision of social housing for the population of the region and those forced to leave their place of residence. Development of mechanisms and means of housing construction, economic stabilization and revival of the country require further development and scientific research
