Real Analysis is the subjects to help the students in critical thought. Students must have the definitions and theorems to solve the problems and perform a process which is often called the preliminary analysis. After that, students construct the proof based on the preliminary analysis. Based on the characteristics of the problem in Real Analysis, the solution given to the problem is using flow proof in composing preliminary analysis The research shows that the student's ability in analyzing can be improved by using flow proof

Abstract – The nutmeg production of West Sumatra since 2011-2018 has decreased fluctuately, so that influenced society economi. The purpose of this research was to know the model and nutmeg production prediction result for the next time, also to know wich regency/town are not exploit the land optimally. The method that used was Tripel Exponential Smoothing Brown with parameter a and Profile Analysis. When determining parameter a, the Mean Square Error is used. While profile analysis was determined by comparing amount of product of land area with amount of nutmeg production, so that used parallelism test, coincidance, and level. The data that used was secondary data which it was obtained Central Static Agency publication of West Sumatra 2012-2019. The nutmeg prediction result at 2019-2023 sequentially in tonnes are 1255.95, 1261.38, 1266.94, 1272.65 and 1278.49. Here are some region that are not optimal yet, among them: Mentawai Island Regency, South Pesisir, Padang Pariaman, and Padang City. Keywords – total production nutmeg, triple exponential smoothing brown type, profile analysis.

Export is the activity of selling goods and services produced domestically to foreign countries. Meanwhile, import is the activity of purchasing goods and services made abroad into the country. If the value of exports and imports experiences instability, the country's economy will also experience instability which will have an impact on the country's income. For this reason, it is necessary to describe the comparison of the value of exports and imports in the province of West Sumatra according to the Standard International Trade Classification (SITC) using profile analysis. This research aims to determine the class of goods according to the Standard International Trade Classification (SITC) which is optimal using profile analysis. In the profile analysis, a comparison of the average value of exports and imports is carried out using the parallelism test, the overlap test and the level test and continued testing for each variable. The results of the tests that have been carried out are that the item code 4 (vegetable and animal oil/fat) has developed well.

In this case, regression analysis with classical method can be used wherethe value of x0 can be predicted based on the dependent variable y0. The purpose of this study is to create a model and determine the prediction interval from forecasting the numberofkamang cracker production based on the profit obtained from the production. The data used are primary data obtained from 25 business houses inKecamatanKamang Magek . From the prediction results obtained, it can be interpretationthe number of kamangcrackers that must be produced

Cocoa is an important commodity for Indonesia. The area and production of cocoa during the last decade decreased by 0.39% and 0.41% per year, respectively. This study aims to find a model and predict Indonesian cocoa production. This study using Autoregressive Distributed Lag (ARDL) method. The ARDL model (1, 3, 2, 2) was obtained which was selected based on the smallest Akaike Integration Criteria (AIC) value. Based on the ARDL model, the estimated average production increases by 0.6684 tons for a decrease in production of 1 ton at t-1. The estimated average production increased by 0.6130 tons for an increase in plant area of 1 Ha at time t, an increase of 0.0257 tons for an increase in plant area to produce 1 Ha at t-1, an increase of 0.5043 tons for an increase in plant area produce 1 Ha at t-2, an increase of 0.3308 tons for an increase in plant area to produce 1 Ha at t-3. Likewise for the increase or decrease area of immature plants and damaged plants in the ARDL model can be interpreted in this way.
