Almost all people in Indonesia today, if they want to do treatment or referrals, they must go to the puskesmas. So this study tries to analyze the services of the puskesmas and evaluate the queues in the puskesmas using the Promodel simulation. Simulation is considered as a suitable tool for analyzing service queues at puskesmas. The results of this study indicate the need to increase the number of doctors to 2 to 3 people to reduce the number of queues that accumulate waiting to be examined by a doctor. If the additional doctor points cannot be met, then the puskesmas can provide adequate waiting room facilities for patients to be examined by a doctor, the ideal number of waiting room seats for patients waiting to be examined by a doctor is 38 seats.","PeriodicalId":434078,"journal":{"name":"Sainteks: Jurnal Sains dan Teknik","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129637205","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the treatment method is chemical treatment with coagulation-flocculation method. Pond water of silver catfish was treated into clean water using powder of Moringa seed (Moringa oleifera) as organic coagulant using coagulation-flocculation method with Jar-Test system. The aim of this research is to purify water with knowing the removal efficiency of color, turbidity, and organic compound by treating pond water of silver catfish using coagulation-flocculation method and determining optimum dose of coagulant.

A good company will predict the production of products that will be achieved, for the future and can help solve the problem of fluctuating conditions which generally often become a problem in the company. Forecasting demand (demand), is very helpful for companies to consider in carrying out the production process in the next several periods. Furthermore, to find out what method is suitable for the forecasting method, it is used by knowing the patterns and historical data. Accuracy in using the right forecasting method is expected to assist the company in determining the level of production in accordance with consumer demand in the future. Time-series models are methods that predict the future using historical data. Time-series models make the assumption that what happens in the future is a function of what has happened in the past. The advantage of time-series models is that they can see what has happened over a period of time and use a series of past data to make predictions. The application of the right and directed forecasting method can support the company to make optimal sales in order to achieve the maximum level of profit. \u0000","PeriodicalId":434078,"journal":{"name":"Sainteks: Jurnal Sains dan Teknik","volume":"192 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132882571","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To reduce environmental pollution and sludge treatment costs, the sludge will be used as raw material for the manufacture of iron coagulant. This study aims to determine whether the sludge from textile WWTP can be used as raw material for iron coagulant. To determine the effectiveness of coagulants made from sludge, this study will compare the results of the coagulation-flocculation process using commercial iron coagulants and iron coagulants made from sludge as well as mixed coagulants with ratios of commercial iron coagulants to iron coagulants made from sludge of 70%, 60%, 50%, 40%, and 30%. The water quality resulting from the coagulation-flocculation process was indicated by pH, color turbidity, Total Dissolved Solid (TDS) and Total Suspended Solid (TSS). The results showed that the water quality of the coagulation-flocculation process was worse when mixed coagulant was used with a smaller ratio of commercial iron coagulant to iron coagulant made from sludge. A mixture of commercial iron coagulant and iron coagulant made from sludge that meets the quality standard for the TSS parameter is a mixed coagulant with a v/v ratio of 70%, while those less than 70% do not meet the quality standard. \u0000","PeriodicalId":434078,"journal":{"name":"Sainteks: Jurnal Sains dan Teknik","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128800640","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study uses quantitative and descriptive methods in measuring the dimensions of employee productivity where the research data used is population data which is all employees in the production section. Based on the results of the study, it is known that the decrease in productivity is caused by the poor attitude and behavior of employees at work. This is indicated by the presence of other movements in addition to the core movement in making products such as using a mobile phone, chatting, etc. at work.

In the line of merchandise business, there is a problem with this business. Namely that the sales target that has been set by the company has never been achieved, while the business opportunity is still wide. As a first step, identification of the company's external and internal business data is carried out. There are five problem-solving models used for data processing, namely the SAP and ETOP systematic approaches to critically identify external and internal factors, the IFE and EFE matrices, which are Input Stages that function to evaluate external and internal evaluation factors, while for the Matching Stage, only two matrices are used, namely the IE matrix to position the SBU in a 9-cell matrix, and the SWOT matrix to formulate the company's strategy, while the QSPM, which is the Decision Stage, functions to choose the The results of the IFE and EFE matrices are (2.66; 2.55) so that the position of the SBU in the IE matrix is in cell V, which results in a hold and maintain strategy. The general strategies used are market penetration strategy and product development strategy. The SWOT matrix produces nine alternative strategy formulations. At the Decision Stage, QSPM uses an alternative strategy from the IE matrix, because it is considered that nine alternative strategies from the SWOT matrix have been reflected in the hold and maintain strategy. So, the results of QSPM data processing produce Sum TAS 6.63 for market penetration strategy and 5.15 for Sum TAS product development strategy. So the market penetration strategy was chosen as the right strategy for the C59 merchandise business line. The market penetration strategy planning program is made in the form of action plans and gantt charts, namely providing examples of merchandise products, giving discounts and competitive product prices, helping with the cost of printing campus/school bulletins by installing a logo, participating in campus events, and sponsoring school/campus activities. \u0000","PeriodicalId":434078,"journal":{"name":"Sainteks: Jurnal Sains dan Teknik","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116827163","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
