Abstract

Matematika banyak diterapkan di berbagai bidang keilmuan, seperti sains, teknologi, ekonomi termasuk dalam bidang agama. Salah satu penerapan penting matematika dalam agama khususnya agama Islam adalah dalam menentukan arah kiblat. Hal ini penting karena kondisi permukaan bumi yang terus berubah akibat pergeseran lempeng sehingga arah kiblat secara kontinu akan terus dilakukan. Hasil dan pembahasan dalam artikel ini diperoleh melalui kajian literatur dengan cara mengkonstruksi  definisi dan teorema yang berkaitan dengan bentuk permukaan bumi, dan perhitungan geometris pada elipsoid. Dengan menggunakan prinsip geometri bola, segitiga bola dan trigonometri bola yang mencerminkan bentuk bumi yang berupa ellipsoid dapat dirumuskan cara menghitung arah kiblat untuk setiap daerah di permukaan bumi, yaitu dengan menggunakan aturan kosinus sebagai berikut: cos B= (cos b - cos a cos c)/sin a sin c. Selain itu disajikan pula bagaimana penggunaan rumus tersebut dengan menerapkan teknologi Google Earth dalam contoh konkrit penentuan arah kiblat dari suatu kota di Indonesia ke Kabah. Ketepatan penentuan koordinat lokasi menjadi penentu presisi dari sudut arah kiblat. [There are numerous applications of mathematics in other fields such as science, technology, economics and religion. One of the most important application of mathematics in religion is its use in deciding the direction of Kaaba for Moslem. This problem is important since the earth surface periodically changes due to the tectonic shift. The result of this study retrieved from literature study by constructing both the definitions and theorems of earth surface and geometrics calculation on ellipsoid. Using the spherical geometry, spherical trigonometry, and spherical triangle the formula to calculate the angle of Kaaba direction from particular point was constructed as follows: cos B= (cos b - cos a cos c)/sin a sin c. Further, the explanation of how to use and calculate the formula was also presented in this paper using the asssistance of Google earth technology. To sum up, the precision of coordinate of location becames main factor to obtain exact angle.]

Abstract

University of Muhammadiyah Gresik (UMG) was one of the colleges established in east Java province as the responsible manager of the essential ecosystem area (KEE) mangrove Ujungpangkah. This activity is intended to socialize the importance of ecological education in supporting the success of the deployment of KEE mangrove ujungpangkah status. This study method was a survey conducted by the questionnaire spread to 40 local teachers from elementary school to high school. The questionnaires are collected through the google form. The responders' answers are analyzed descriptively based on their centrality and diversity analysis. The solution in an essay is based on its essence, based on the impelling of ecological education at KEE mengrokah. Based on the results, 100% of respondents consider it is essential to promote ecological education in the Gresik area. 25% do not know about KEE, and 75% have found out about KEE. Based on the data obtained, it is concluded that ecological education needs to be performed and socialized to the community so that the participation from the community is also increasing.

Abstract

The essential ecosystem of mangroves Ujungpangkah (KEE MUP) is a protection and limited utilization area located on the coastal area in the north of Gresik Regency. This area has high biodiversity, especially various mangroves and waterbird species from different parts of the world due to their migration process. To protect this area, it is required to enhance the sensitivity of students as the young generation to react appropriately to keep the environment sustainable. In this case, education-based environmental studies (Ecological Education) is used as a sustainable approach to answering this challenge. Various activities of community services are structured through a strategic plan for ecological education implementation. With this Ecological Education, students can increase their sense of love for the environment to keep the KEE MUP conservation zone inherited sustainably
