<![CDATA[Abstract – One of the problems that can happen to the insurance company is the inability of the company to pay compensation to the insurance participants in the event of a claim. For that, it takes a formulation of premium calculation so that the premium value can be calculated properly. Calculation of net premium using Heligman-Pollard law. The calculation of premiums by using Heligman-Pollard law begins with creating mortalitaas tables, making the cash value of dual-purpose annuity insurance with dependents for n years, calculating net periodic premiums on dual life insurance with multiple life cases, calculating annual net premiums on dual-life insurance with multiple cases life. By using this Heligman-Pollard law, insurance premiums will be grouped into 3 age groups on the new mortality table.]]>

<![CDATA[Abstract - Puyuh is a kind of livestock which is popularly known as one of some animal protein source. The farmer should be able to formulate a right way to gain profit from the production which is proper with the need. Thus, it is important to make a calculation to predict the number of the livestock which have to be farmed according to profit of the production by using Inverse Regression classical prediction method that it can be predicted the value of gained from response variable at the prediction model. This research is aimed to determine the model and interval of prediction to predict the number of puyuh which have to be farmed according to profit of the production. From the result of the Inverse Regression classical prediction method and interval of the prediction which is got can be interpreted that the quantity of production number which is needed depends on profit of the production and average of number of puyuh farming production. ]]>

<![CDATA[Abstract – This research discuss about forecasting of the total restaurant and hotels tax at Padang City use a method of exponential smoothing triple tipe Brown. The fact is the number of visitors hotel and restaurants comes not constant or not sure yet on each year. Therefore the method forecasting can be a right solution is estimate that the number of the tax restaurant and hotel in future time. The purpose on this research is to estimate receipt of the number of the tax hotel and restaurants at Padang City on the next five years. The method used to forecast the number of the tax restaurant and hotel at Pada City of the is the method of exponential smoothing triple tipe Brown. Based on the research results obtained by the model exponential smoothing triple tipe Brown the right to use in forecasting revenue amount restsurant and hotels tax at Padang City is F_(10+m)=51.688.474.068+7.812.509.304m+349.042.638,65m^2, with the number of periods (m) is one until five.]]>

<![CDATA[Abstract - This study discusses about the factors of causing hypertensive by using factor analysis methods in Clinic BALAD of Pariaman City. BALAD Clinic of Pariaman city cares for hypertension patients which always increases every year from 2015 until 2017. This study aims to determine the factors that cause hypertension at the BALAD Clinic including age, heredity, exercise, smoking, food and drink, and psychological. This type of research is applied research using primary data. The population in this study all patients who suffer from hypertension August 2017 - April 2018 in Clinical BALAD many as 170 people. Sampling with accidental sampling means that samples taken by chance encountered in the clinic BALAD. Based on the results of research known that the factors of causing hypertension in Clinic BALAD is a factor built by food and psychological variables and factors built by variables of descent and smoking.]]>

<![CDATA[Abstract – There are so many candidates and criterias in the process of Bidikmisi scolarship selection, but the awardees are limited. Therefore, we need an accurate method to gain precise decision. This research used Technique for Oder Preference by Similarity to Ideal Solution (TOPSIS) Fuzzy Multi Additive Decision Making (FMADM) method to Bidikmisi scolarhip selection. Bidikmisi scolarship selection in this research there are five criterias were determined, they are: parents income, life cost, the status of the house ownership, the land area, and the building area. The rating of the criteria have been done subjectively and objectively. Subjectively, the rating is gain from experts opinion and objectively the rating is gain from the result of TOPSIS. The output are the participants preference value. Based on the result of these research, the preference value are more accurate therefore only a few candidates have the same value. So this research proves that the ranking process have been done more carefully.]]>

<![CDATA[Abstract – This study discusses the characteristics of Maxwell-Boltzmann distribution. Each distribution has its own characteristics. The characteristics can be seen in the parameters are mean, variance, skewness, kurtosis, moment generating function and characteristic function. The purpose of this study is to determine the characteristics of the Maxwell-Boltzmann distribution. The steps of this research are looking for the mean, variance, skewness, kurtosis, moment generating function, and characteristic function of the Maxwell-Boltzmann distribution. The results of this research were obtained the parameters of the Maxwell-Boltzmann distribution: mean variance, skewness, kurtosis, generating function of the momen and characteristic function.]]>

<![CDATA[Abstract– Toxoplasmosis is a disease that affected by Toxoplasma gondii parasite which have latent (asymptomatic) characteristic. Toxoplasmosis disease was spreading vertically and horizontally. Spreading vertically through mother to kids and spreading horizontally through uncooked that contain of ookista. Toxoplasmosis disease can affect to serious health problems including physical disability, miscarriage and death. To determine influence level of Toxoplasmosis disease spreading, mathematic model was divided population by four individual groups: susceptible individual, latent individual, infection individual and controlled individual. Mathematical model formed was analysed by looking at its stability, analysis result was obtained fixed stability point. Increase in sum of individuals Toxoplasmosis disease spreading was affected by three parameters, which were susceptible individual moving to latent individual due to consume the foods that contain of ookista, individual that infected due to decrease immune system, and controlled individual or given treatment. ]]>

<![CDATA[Abstract – This study discusses the optimization of production planning . Optimation is done by using goal programming method on the product of Kerupuk Bawang Fajar in Indarung Padang. Problems that occur in this business is less optimal implementation of onion cracker production. The production process is not through careful planning. So often the excess of raw materials. This research’s purpose is to know the model for production planning and to know the result of production planning optimization on Kerupuk Bawang Fajar by using goal programming method. The form of goal programming model is an extension of linear programming, it’s just there are deviasional variables on the function constraints that serve to accommodate the deviation of the completion of the goal to be achieved. The optimal production of Kerupuk Bawang Fajar is the original garlic cracker as much as 792 packs / day, spicy onion cracker as much as 130 packs / day, carrot flavor cracker as much as 151 packs / day, potato garlic crackers as much as 130 packs / day, and purple sweet potato crackers as much as 90 packs / day. With profit maximization of Rp. 12.167.291 and a minimization costs of Rp 3.373.378.]]>
