The problem that always occurs in STMIK Royal in each semester is first, the delay in students preparing the Study Plan Card (SPC) due to the late students themselves paying tuition so that the difficulties for study programs in recording student activity data, then harming the students themselves because they are considered absent during not enrolled in lectures. Second, 90% of the students who get the final grade below are enough due to the lack of lecture meetings from the minimum number of meetings that have been determined by the academic, so students must repeat their studies in the next semester. This situation forces the study program section to be able to condition schedules, classes, and lecturers for students who repeat. For this reason, a monitoring system for tuition payments and student attendance is required based on the SMS Gateway. Through this system, academic parties can disseminate information on tuition payments and student attendance to parents or parents to monitor tuition payments and student attendance through services provided by the system.

Abstract: Sembako is an abbreviation of Nine Basic Ingredients which consists of various food and beverage ingredients that are generally needed by the people of Indonesia. Without basic necessities, the lives of the Indonesian people can be disrupted because basic necessities are daily necessities that are freely sold in the market. Toko Suryono is one of the basic food distributors that sells various kinds of basic necessities. The problem is that the number of food sales every month is erratic so it is difficult to predict, so we need a sales system and strategy, one of which is by predicting or forecasting sales for the future process so that this store knows how much food supplies must be provided in the following month so that there is no shortage or excess stock. The result of this research is that forecasting using themethod Least Square can make it easier for the store to provide basic food supplies in the coming month. From the overall calculation of basic needs, the lowest MAD is 16.51 and MAPE is 1.73%. Keywords: Forecasting; Total Food Sales; Least Square; Abstrak: Sembako adalah singkatan dari Sembilan Bahan Pokok yang terdiri dari berbagai bahan makanan dan minuman yang umumnya dibutuhkan oleh masyarakat Indonesia.
