Plant morphology modeling can be done mathematically which includes roots, stems, leaves, to flower. Modeling of plant stems using the Lindenmayer System (L-system) method is a writing returns that are repeated to form a visualization of an object. Deterministic L-system method is carried out by predicting the possible shape of a plant stem using its iterative writing rules based on the original object photo. The purpose of this study is to find a model of the plant stem with Deterministic Lindenmayer System method which will later be divided into two dimensional space three. The research was conducted by identifying objects in the form of pine tree trunks measured by the angle, thickness, and length of the stem. Then a deterministic and parametric model is built with L-system components . The stage is continued by visualizing the model in two dimensions and three dimensions. The result of this research is a visualization of a plant stem model that is close to the original. Addition color, thickness of the stem, as well as the parametric writing is done to get the results resembles the original. The iteration is limited to less than 20 iterations so that the simulation runs optimal.

L-Systems memiliki fleksibilitas dalam mensimulasikan struktur dan proses pengembangan pertumbuhan tanaman secara visual dan realistik. Penelitian ini bertujuan untuk memodelkan pertumbuhan tanaman jagung menggunakan L-Systems dan memvisualisasikan model pertumbuhan tanaman jagung tersebut dari kecil hingga dewasa dalam ruang dimensi tiga. Penelitian dilakukan dalam tiga tahap yang diawali dari identifikasi kebutuhan data tehadap pertumbuhan tanaman jagung (Zea Mays L.). Tahap kedua, membangun model secara manual yang meliputi identifikasi dan penentuan komponen L-Systems (huruf, aksioma, dan aturan produksi). Tahap ketiga, melakukan simulasi dan visualisasi model pertumbuhan tanaman jagung yang telah didapat menggunakan processing dengan bahasa java dalam ruang dimensi tiga. Ketiga tahapan tersebut menghasilkan model Stochastic L-Systems dari pertumbuhan tanaman jagung dalam ruang dimensi tiga. Visualisasi model tanaman jagung yang telah dihasilkan pada penelitian ini lebih menekankan pada penyempurnaan model yang dilakukan pada penelitian sebelumnya terutama pada pewarnaan, pembentukan batang, dan adanya tulang daun pada tanaman jagung setiap iterasinya. Model tanaman jagung divisualisasikan mulai dari kecil hingga dewasa (fase vegetatif) yang memiliki tulang daun dan kelengkungan daun berbeda dari daun bawah sampai pada daun atas. Tanaman jagung yang divisualisasikan hanya terbatas sampai 8 iterasi saja yang sudah mampu mewakili pertumbuhan tanaman jagung pada fase vegetatif

Indonesia is known as a country with a majority Muslim population, this makes the need for clothing in Indonesia must also pay attention to the criteria for Muslim clothing, one of which is the hijab. Business developments in the fashion world, especially hijab, have become a trend setter at this time so that the large amount of data in the fashion business world creates conditions where there are businesspeople who have a lot of data but lack of information from that data. To deal with these conditions, it is necessary to classify the data. A classification is a process to find the same properties in a data set to be classified into different classes.  One of the classification methods is the Decision tree using the C4.5 Algorithm.  This research aims to determine the model and the accuracy of the C4.5 algorithm in classifying hijab sales from several hijab brands.  The Decision tree model is obtained using the C4.5 algorithm with the first root being the price attribute, where the first root is the attribute that most affected the sale of the hijab.  The result of calculating the accuracy value is 87% so that the Decision tree model and the classification process using the C4.5 Algorithm are classified as good. This research is expected to help businesspeople in the fashion sector, especially hijab, to find out the factors that influence consumer interest in a hijab product.

Upaya pemerintah mengajak masyarakat desa melakukan wirausaha mulai menunjukkan langkahkonkrit sejak digalakkannya pendirian badan usaha milik desa (BUMDes). Setiap desa diharapkandapat membentuk badan usaha yang mempunyai pengurus dan obyek yang dapat dijadikan wahanabisnis. Desa Donoharjo yang terletak di Kecamatan Ngaglik Kabupaten Sleman mempunyai obyekwisata menarik berupa embung Jetis Suruh, tetapi belum terkelola dengan baik. Pendirian BUMDesdengan basis pariwisata menjadi upaya konkrit Desa Donoharjo untuk mengembangkan desanya.Melihat potensi tersebut, dilakukan pra-survey ke lokasi dan dilakukan wawancara dengan berbagaipihak sehingga teridentifikasi permasalahan berikut: 1) belum adanya pengelola yang mumpuni untukmengelola embung Jetis Suruh menjadi obyek wisata unggulan, 2) belum adanya dokumen tata kelolapelaksanaan BUMDes, 3) belum adanya perencanaan untuk pengembangan lembaga, 4) belum adanyapembagian tugas di antara pengelola, 5) belum tersedianya media akun medsos dan web, 6) belumtersedianya paket wisata, 7) belum adanya cinderamata khas Donoharjo, dan 8) kurangnya pembinaanterhadap kelompok kesenian tradisional. Melalui program penyiapan BUMDes berbasis pariwisatadiperoleh output berupa: terbentuknya pengurus BUMDes Donoharjo, dokumen tata kelola AD/ART,media promosi yang interaktif, dan tersedianya perencanaan yang komprehensif (Renstra). Melaluipendampingan manajemen yang intensif, BUMDes Donoharjo menjadi usaha profit dengan berbagaiprogram yang produktif serta menambah pendapatan desa.

This research aimed to obtain construction procedures lampshade form through incorporation and election of parameters shape shifter Bezier surface. Thus, it product a sholid lampshade that both symmetrical and varied. In contruction lampshade it requires learning about the physical (expose) and geometrical aspects. In terms of geometry model-making of lampshade sitting which has existed in general still monotone and built of object cut model. Dealing with the problem, so this research is divided into four stages: Firstly, prepare the data of building sitting lampshade. Secondly, study about technique of building symmetrical sitting lampshade. Thirdly, construct overall lampshade. The results of this research is procedures by contruction of sitting lampshade: First, The main axis split into three sub segments axis non-homogeneous. Second, build parts of the sitting lampshade (the base, the main part, the roof) by combining the components lampshade deformation results geometry objects. Third, fill each sub-segment of non-homogeneous parts with parts of the lampshade and build a boundary curve resulting lampshade varied models, innovation, and symmetry.
