Salah satu metode dengan penggunaan data masa lampau untuk melakukan prediksi adalah dengan metode regresi linier. Pada penelitian ini yang menjadi variabel bebas adalah periode tahun akademik sedangkan yang menjadi variabel terikat adalah jumlah mahasiswa baru. Data yang akan digunakan merupakan data mahasiswa baru fakultas sains dan teknologi yang terdiri dari 6 program studi dengan nilai MAPE (Mean Absolute Percentage Error) yaitu matematika , ilmu kelautan , biologi , sistem informasi , arsitektur , dan teknik lingkungan . Berdasarkan hasil analisis data tersebut juga didapatkan prediksi jumlah mahasiswa baru 5 tahun kedepan dengan hasil cenderung turun untuk setiap program studi.","PeriodicalId":259622,"journal":{"name":"JURNAL ILMIAH MATEMATIKA DAN TERAPAN","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131329041","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}

However, the two regression models cannot solve the excess zero and overdispersion problems so use the Hurdle Negative Binomial (HNB) regression model. The results of the analysis of cigarette consumption data in Central Sulawesi Province using the HNB model provide the best modeling results compared to the poisson regression model and the ZIP model because it has the smallest Akaike's Information Criterion (AIC) value.

One of the methods used was Saving Matrix, which in its operation could efficient the delivery route so that the minimum total distance was obtained. The company's actual mileage was greater than the distance travelled by the route after using the Saving Matrix method.

The disease is caused by the Schistosoma japonicum worm which requires an intermediary host, namely the Oncomelania hupensis lindoensis snail, which is an endemic animal in the area. This study examined mathematically the control of the spread of Schistosomiasis by using ducks as natural enemies for intermediate snails. The human population is divided into vulnerable human subpopulations and a subpopulation of infected humans. Interactions between snail populations and duck populations are expressed as interactions between Predator and Prey. The Schistosoma japonicum worm population is seen as a population growth cycle model. The stability of the model is analyzed using the Jacobi matrix, which is evaluated at a critical point. The model has two critical points 𝑇1 and 𝑇2 which represent a disease-free conditions, while 𝑇3 represents endemic point. Mathematical model simulations controlling the spread of Schistosomiasis. The simulation is using ducks with early populations indicate that disease control by using ducks is less effective because it takes a very long time to be estimated at 55 years.
