Abstract

Keberadaan Posyandu Teratai di RW 21, desa Ciwidey, Kabupaten Bandung sangat diperlukan warga desa karena terletak strategis di tengah pemukiman warga dan akses jalan yang mudah dicapai dari perumahan warga desa Ciwidey. Oleh sebab itu fungsi Posyandu dimanfaatkan oleh masyarakat sebagai ruang multi fungsi yang berperan ganda seperti timbang bayi, pemeriksaan kesehatan ibu dan anak, kegiatan untuk remaja, dan kegiatan warga desa. Permasalahan pengabdian ini bagian dinding luar Posyandu belum dimanfaatkan sebagai dinding yang mengedukasi bagi publik. Hal inilah yang menjadikan Kepala Desa berinisiatif untuk memanfaatkannya, dengan menambahkan mural yang dapat mengedukasi warga desa. Tujuannya untuk menciptakan dinding yang mengedukasi dan menjadi area spot yang menarik perhatian diantara lingkungan hijau desa Ciwidey. Metode yang dipergunakan Asset-Based Community Development (ABCD) dan angket, hal ini untuk mengetahui manfaat mural bagi kesehatan masyarakat. Hasilnya mural dibuat mengelilingi dinding posyandu dengan gaya dekoratif dan warna yang mencolok agar terlihat eye catching di antara lingkungan hijau. Simpulannya, Posyandu di kawasan desa Ciwidey menjadi point of interest diantara lingkungan hijau, dan menjadi area spot yang menyenangkan bagi warga.

Abstract

Indonesia is dominated by cities that have a history of batik, but Purwakarta does not have a history of batik. But thanks to the persistence of policy holders, Purwakarta currently has batik obtained by elevating the local wisdom of the city of Purwakarta. After surveys and interviews, several batik motifs were designed. The batik motif shape, size and position will be studied which will formulate mathematical equations based on basic geometric shapes such as circles, arches, lines, rectangles, which are implemented into the form of computer graphics (turtles) graph and explained in the form of an algorithm (pseudocode) computer programming to make autogenerative motifs on Purwakarta batik that did not exist before. Batik design is inspired by food and tourist locations which form the basis of the formation of typical Purwakarta batik motifs. Jatiluhur Dam, Datura Metel L. Flower, Sate Maranggi, Mangosteen Fruit is a local wisdom owned by the city of Purwakarta. The results of the morning glory batik design and Jatiluhur dew through mathematical and turtle charts are then formulated so that the batik motif design can be saved by documenting the mathematical equation or the pseudocode of the batik motif. With the results of digital motifs, the process of repeating patterns, duplicating and storing data becomes easier.

Abstract

In this world, the shapes of objects, including Batik motifs in Indonesia, are regular and irregular. One of the regular Batik motifs is Surya Kawung Batik from Mojokerto. The purpose of this research is to observe the ability of the Electrical Engineering Department students in Maranatha Christian University to study and reconstruct the geometric shapes of Surya Kawung Batik. In the making of the Batik motifs, the research methods employed are survey, observation, exploration, testing, and improvement, while in the learning process, the method applied is descriptive qualitative, in which the researchers check the data credibility. Turtle graphics algorithm and mathematical calculations are used to form Batik geometric motifs. The result of this research shows an increase in the students' ability to learn the geometric shapes and to reconstruct digital Batik motifs which resemble the original Batik motifs and which can be stored using a smaller memory. If the memory for storing motifs is small, the required storage space will be more efficient.

Abstract

West Java has a centre for craftsmen who have a variety of motifs drawn from their regional potential. One of them is Ciamis batik, but now with the pandemic of the Corona 19 virus, it has had a tremendous impact on the macro and micro industrial economy in the development of the batik business. More and more are stopping their business. So it is feared that Ciamis batik motifs are increasingly rare in the market. Through Turtle graphics, existing batik motifs are made in the form of vector images to be preserved by utilizing digital technology. This research has the aim to that the Ciamis batik motif can be made into a visual language through the digitalization process using the MuPAD programming language. The benefit is to document and reintroduce Ciamis Batik motifs that are almost extinct. The method used is a digitalization experiment through the Lindenmayer System. Ciamis batik samples selected motifs that have repetition in the form of a repeating pattern. Based on the research, the Ciamis batik motif can be made using the technique of arches, horizontal lines, vertical lines, and rotation. The conclusion of this research is that batik motif design can use the Lindenmayer System program as a blueprint and can be implemented on Indonesian batik.  This research contributes to the efficient documentation of batik motifs in digital form with good quality so that they can be implemented in the creative industry.

Abstract

The problem is how students can learn independently when no assistant teachers are present. The main objective of this research is to build an application system that can recognize the stances in Ibing Penca martial art. This research aims to help facilitate independent learning for martial arts practitioners, especially Ibing Penca, by developing a system that is able to recognize and classify the movements in 62 Ibing Penca stances. To achieve these goals, the research method used is to collect input data in the form of images or videos taken using an Orbbec camera. After the images are obtained, the next stage is data processing to detect important points on the body using landmark detection techniques. The next process is the identification of 33 keypoints on the body using the MediaPipe algorithm. From these keypoints, six important angles were calculated which included the right arm, left arm, right leg, left leg, right foot and left foot. This angle calculation is done using the angle method of the three relevant key points. The system is able to recognize the movements in Ibing Penca with a high degree of accuracy, which is very useful for learners who want to practice independently. The results of this study show that the system is able to classify 62 Ibing Penca moves with a success rate of 95.2% (58 moves), while the error rate is only 4.8% (4 moves). For future research, it is expected to develop this system by adding variations of movements and improving detection accuracy in more diverse environmental conditions.
