The preparation of production planning is related to the optimization of a company’s production, so that a company can run effective and have low cost production activities. The preparation of production planning need to pay attention at many things because a company has various goals to achieve. Goal programming is a method to model a problem that has many goals so that the optimal solution will be obtained from many targets at once. This study aims to optimize the production of suwar-suwir at the Sari Rasa Factory located in Jember Regency by applying the goal programming method. Existing data will used to create a model using goal programming method to get the optimization results. The goal programming formulation is formed by determining the decision variables, goal constraints, and objective functions. The optimization calculation in the goal programming method will use the LINDO (Linear Interactive Discrete Optimizer) software. The results in this study show that production cost can be minimized from Rp 57.616.000 to Rp 51.782.000, existing raw materials can be minimized from 104 recipes to 94 recipes, and the optimal profit is Rp 18.508.000.","PeriodicalId":31699,"journal":{"name":"JMPM Jurnal Matematika dan Pendidikan Matematika","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80701838","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}

The Box-Jenkins ARIMA method can produce accurate predictions, but it is less precise when used to predict data that has a heteroscedasticity effect. Therefore, this study uses the ARIMA-GARCH method because this model has the advantage of not seeing heteroscedasticity as a problem but instead using it to create a model. The purpose of this study is to estimate parameters using the ARIMA-GARCH technique to develop the best model using PT Unilever Indonesia's share price data and to forecast PT Unilever Indonesia's share price for the period January 20 to January 28, 2021, using the best ARIMA-GARCH model created.

Tujuan ini melibatkan penelitian tentang apakah pengaruh model pembelajaran terhadap kemampuan komunikasi matematis siswa dipengaruhi oleh kemampuan awal matematika mereka. Penelitian ini menggunakan metode eksperimen. Populasi penelitian terdiri dari siswa di SMK Swasta Muhammad Yaasiin Sei Lepan, sedangkan sampel penelitian ini terdiri dari siswa kelas XI-1 dan XI-2 pada jurusan TKJ. Dari kedua kelas tersebut, kelas XI-1 dijadikan sebagai kelompok eksperimen yang mendapatkan pembelajaran melalui model PBL, sedangkan kelas XI-2 dijadikan sebagai kelompok kontrol yang mendapatkan pembelajaran melalui model pembelajaran ekspositori. Data yang dikumpulkan akan dianalisis menggunakan metode statistik ANOVA 2 jalur. Hasil penelitian menunjukkan bahwa: 1) Terdapat perbedaan yang signifikan dalam kemampuan komunikasi matematis siswa antara kelompok yang diajarkan melalui model PBL dan kelompok yang diajarkan melalui model pembelajaran ekspositori. 2) Tidak terdapat interaksi yang signifikan antara model pembelajaran dan kemampuan awal matematika siswa terhadap kemampuan komunikasi matematis siswa. Artinya, pengaruh model pembelajaran terhadap kemampuan komunikasi matematis siswa tidak dipengaruhi oleh kemampuan awal matematika mereka. Dengan demikian, hasil penelitian ini menunjukkan bahwa model PBL memiliki dampak positif terhadap kemampuan komunikasi matematis siswa dan dapat menjadi pilihan yang efektif dalam meningkatkan kemampuan komunikasi matematis dalam konteks pembelajaran matematika.","PeriodicalId":31699,"journal":{"name":"JMPM Jurnal Matematika dan Pendidikan Matematika","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136366424","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}
