INTRODUCTION
Bendesa Adat is a term from a village head who has a special duty in the area of adat or religion in a traditional village in Bali. Bendesa Adat has the duty to regulate religious ceremonies or often called piodalan and the provision of dewasa ayu for the community in the village they lead [1]. Dewasa ayu have the meaning of a good day of the yadnya ceremony taking into account the character or traits of a day [2]. Dewasa ayu are believed to be able to influence safety in a fairly long period of time [3]. The calculation of the character or traits of the day can be done by looking at wuku, sasih, pengalantaka and also the wewaran that is in the Balinese Calendar. The Balinese calendar also has an important role in carrying out Hindu religious ceremony day and can also search for birthdays and determine one's personal characteristics [4]. Of course not everyone knows the timing of the ceremony, so that Bendesa Adat is needed which specifically coordinates in the religious field in the village [5].
The solution that could be given based on the problems experienced by some people are to make a mobile-based application that gives the community basic knowledge about the time of conducting religious or piodalan ceremonies, dewasa ayu and Hindu religious ceremony day so that people know what date and month there are the time of the religious ceremony. The concept used in making this application is almost the same as conventional Balinese Calendar, this application will make it easier for people to know about ceremony day, piodalan and dewasa ayu, especially for dewasa ayu pengabenan and also marriage by referring to Wariga Padewasan book [6].

Balinese Calender
Balinese calendar is a calendar that develops in the community, especially the people in Bali. The Balinese calendar is used as the basis for taking good days (dewasa ayu) to carry out an activity or conduct religious ceremonies in the community, especially in the area of Bali. Balinese people believe that every activity has a date for each good day. The calendar system generally uses the calculation of wuku, sasih, wewaran and also supplies those are available in the Balinese Calendar [7].

Waterfall Methods
Mobile Note Application for Bendesa Adat at Bali made using the waterfall development method. This method is the stages of application work done sequentially. The stages used are as follows [4]. 1) Analysis Analysis is a stage to collect dewasa ayu data obtained from interviews with Sulinggih and Jero Bendesa as well as from manuals related to the determination of dewasa ayu which will then be translated into the programming language used.

2) Design
The design is the stage of making the program so that it becomes an application in accordance with the data obtained at the analysis stage. This design process is the process of translating the data obtained into a programming language so that it is in accordance with the data used in determining dewasa ayu especially for the Balinese community.
3) Testing Stages of testing are stages carried out with the aim of finding errors, especially in calculation of dewasa ayu before conducting trials with Jero Bendesa.

4) Implementation
The implementation stage is the testing phase using 2 villages as a trial application that has been made.

Dewasa Ayu
Dewasa ayu is a term of the good day of conducting religious ceremonies in the community especially in the area of Bali. Dewasa ayu are used as a benchmark of time to carry out religious ceremonies. Dewasa ayu are usually calculated by wuku, wewaran, pengalantaka and also sasih that exist in Balinese Calendar. Communities in Bali generally believe that every activities that will be carried out has a good day each of which is certainly different in terms of determining the date of its implementation. Basically, dewasa ayu can be calculated by calculating wuku, sasih and also the pengalantaka that exist in Balinese Calendar [8].

Ceremony Day
The ceremony day is a special day that aims to commemorate an event or event that occurred in the past. The ceremony day in Bali is determined according to the calculation of Wuku, Sasih, Wewaran and the Pengalantaka in the Balinese calendar. The calculation of the ceremony especially for Hindu people in Bali can be distinguished into four, namely [9]. 1) Calculation Based on Wewaran Wewaran comes from wara which has the meaning as a day (name of day) which has a number of ten [9]. Each day's name has a different number, from 1 day to 10 days. Usually the most commonly used authority to search for a day for either an activity or a ceremony is triwara, pancawara and also saptawara.

2) Calculation Based on Pengalantaka
Determination of dewasa ayu should also take into account both the penanggal and panglong. The penanggal can be interpreted as the calculation of the days after the occurrence of the tilem (dead moon) until the day before purnama while the panglong calculation of days after the occurrence of purnama (full moon) until the day before the occurrence of tilem [11]. The calculation of the penanggal and panglong is called a pengalantaka. The pengalantaka itself has the meaning of the system of adjustment of tilem (dead moon) and purnama (full moon) according to the position of the moon against the sun and also the earth. This allocation causes the age of the moon not forever 30 days, but the age of the month can also be as many as 29 days. This pengalantaka adjustment aims to equalize the signs that are in the bali calendar with the state of the moon. The ceremony day of the pengalantaka calculation consists of two holidays, namely the full ceremony day and the ceremony of the tilem.

3) Calculations Based on Wewaran and Wuku
Wuku or pawukon comes from a book that is part of the balinese calendar dating cycle which is seven days old [18]. Generally, the pawukon can also be used to count Balinese birthdays, which usually amount to 210 days on a conventional calendar [17]. Wuku system in bali has thirty wuku so my wuku cycle runs as much as two hundred and ten days [12,16].

4) Calculations Based on Pengalantaka and Sasih
The sasih could be interpreted as a month in the calendar. The number of sasih in the Balinese Calendar is equal to the number of months in the year on the conventional calendar commonly used is twelve months, but in one year the Balinese Calendar consists of only 354 days. This sasih usually changes every month just like a typical calendar [14]. The calculation of the ceremony day in the Balinese calendar based on the calculation of the pengalantaka (penanggal and pangelong) as well as the sasih amounted to two ceremony day, namely Nyepi ceremony day and also Siwalatri ceremony day [19].

The Searched Algorithm of The Ceremony Day Raya, Dewasa Ayu and Piodalan Data
The data that used in creating the application divided into three parts, which are ceremony day, the data for Dewasa Ayu, and also the data for Piodalan that obtained from the interview result with the Bendesa Adat Renon. The data would be created on the stored procedure database MySql with the algorithm as follows a. The Algorithm of Ceremony Day The amount of ceremony day data that used in creating the application is fourty seven ceremony day data in total. The algorithm example of ceremony day data that used as stored procedure in the database can be as follows .
The searched algorithm of the data for ceremony day would be created in the stored procedure form which will be saved into the database. The saved database will be shown in the Bendesa Adat file application.

b. The Algorithm of Dewasa Ayu
The data for Dewasa Ayu that used in creating the application can be divided into two data, which is the Dewasa Ayu for the funeral event and the Dewasa Ayu for the wedding event. The algorithm of The Dewasa Ayu data can be as follows The searched algorithm of the data for The wedding Dewasa Ayu will be used as The data for Dewasa Ayu in the application. These algorithms will be created in the stored procedure in the MySql and will be used to show the data for Dewasa Ayu in the application.
c. The Algorithm of Piodalan Piodalan is a religious ceremony in Bali which is held to thank you for giving Ida Sang Hyang Widhi Wasa or God Almighty that is usually performed at every temple in Bali [15]. The data for Piodalan that obtained from the interview will be converted into the computer language so the data can be easier to retrieve. Table 6 The Algorithm of piodalan If (Pancawara = Kliwon, Saptawara = Saniscara, Wuku = Kuningan) Print "Piodalan ring Pura Dalem" The Algorithm of the data for Piodalan will be created in the stored procedure at MySql and then will be used as the data for Piodalan in the Bendesa Adat record applications.

The API Speed Test
The API speed test is intended to test the speed of the data response that used in the Bendesa Adat file application. The test is done using three different devices from the RAM, memory, CPU to the type of device used.  Then, The API response speed will be tested on three different devices. From the table above, it could be concluded that the device affects on the data response that taken in this Bendesa Adat file application. In order to get the average API response, the JMeter application is used and will be set by the 30 users simultaneously logged in to each existing API. The table shows the average time of each API that exists in the Bendesa Adat file application with 30 users simultaneously logged into the API.
