Math and Mate in Javanese Primbon: Ethnomathematics Study

Abstract

Marriage is an essential part of life for most people. In the Javanese tradition, great attention is paid to the weton of the couple through Javanese Primbon. It predicts the fate of the couple in the marriage. This prediction of the Javanese outcome after the wedding has some numerical values. Therefore, this study aims to uncover these numerical values using ethnomathematics. This research uses a qualitative method. Analyzing the Javanese Primbon documents is meant to explore the numerical value of Javanese people. Also, analyzing the data using the Javanese Primbon documents was not only based on the interpretation of the researcher but also the result of discussions with cultural and mathematical experts. This study proposes numerical values such as number bases, remainder theorem, modulo, and modulus of the congruence in formal mathematics, which is associated with matchmaking using Javanese Primbon.

Ethnomathematics: Pranatamangsa System and the Birth-Death Ceremonial in Yogyakarta

“…In Javanese society, the term neptu or weton is also defined as the day of one's birth, which is This neptu calculation is usually used by Javanese people to predict human characteristics, a good day for making events, a good day for traveling, a good day for marriage, predicting compatibility of a prospective spouse, job suitability, and so on. The results of this prediction are written in a book called the Primbon Book, which is a book of ancestral heritage that contains predictions and teachings that come from the relationship between life and the universe (Utami, Sayuti, & Jailani, 2019). A number of these predictions are still used in Javanese society.…”

“…Addition to day = Mourn day (mod 7)-1 In predicting the pasaran day of the deceased one, we apply mathematical modeling integrating modulo 5. Therefore, for those days in a year n which is divisible by five, and it has remainder five (Utami, Sayuti, & Jailani, 2019). The remaining is then subtracted by one because we don't take the deceased day into account.…”

“…Furthermore, Utami, Sayuti, and Jailani (2019) investigated the Javanese pasaran-fortune day (primbon), Sugianto, Abdullah, and Widodo (2019) explored number patterns, 2D figures, and number operations in Reog Ponorogo culture, and Kemaro island legend can be used to teach statistics (Lestariningsih, Putri, & Darmawijoyo, 2012). In addition, several games have been explored as a starting point in learning number operations using bermain satu rumah traditional game (Nasrullah & Zulkardi, 2011), social arithmetic using kubuk manuk games (Risdiyanti, Prahmana, & Shahrill, 2019),…”

Etnomatematika Pada Lopo Suku Boti Dan Integrasinya Dalam Pembelajaran Matematika

“…Wilfridus Beda Nuba Dosinaeng, Meryani Lakapu,Yohanes Ovaritus Jagom, & Irmina Veronika Uskono dalamnya. Sedangkan, istilah matematika merujuk pada pengetahuan matematis seperti membilang, mengukur, menghitung, membandingkan, mendesain, mengklasifikasikan, dan sebagainya (D'Ambrosio, 1985;Utami et al, 2019). Dalam sudut pandang ini, etnomatematika dapat dipahami sebagai matematika yang dihasilkan, digunakan, dikembangkan, dan diwariskan dalam kerangka budaya.…”

Etnomatematika Untuk Siswa Sekolah Menengah:eksplorasi Konsep-Konsep Geometri Pada Budaya Suku Boti

“…Mempelajari perkembangan konsep geometri dalam budaya dan kaitannya dengan geometri sebagai ilmu pengetahuan dapat dilakukan melalui etnomatematika. Dari segi susunan katanya, etnomatematika terdiri dari dua kata yaitu etno-yang merujuk pada budaya dalam pengertian luas, meliputi segala sesuatu terkait budaya seperti nilai-nilai, norma, artefak-artefak budaya, dan -matematika yang merujuk pada pengetahuan-pengetahuan matematis seperti mengukur, membilang, membandingkan, mengurutkan, dan sebagainya (Ambrosio, 1985;Utami, Sayuti, & Jailani, 2019). Secara umum, D'Ambrosio menjelaskan etnomatematika sebagai matematika yang dipraktikkan oleh kelompok budaya tertentu (Ambrosio, 1985).…”
