Abstract

Keberadaan rumah tinggal tradisional Melayu ditepian sungai Kapuas, Kampung Tambelansampit Pontianak memiliki nilai kekhasan fasade rumah tinggal yang berbeda dcengan daerah lain. Sehingga didalam mengidentifikasi jenis/tipe/tipologi dari fasade sebuah rumah tinggal tradisional harus melibatkan aspek tolok ukur sistem model (stylistic system) yang yang berkaitan dengan style atau langgam yang mewujudkan bentuk fasade bangunan. N.J.Habraken (1978) mempertegas pernyataan ini dengan menyatakan bahwa arsitektur rumah tinggal merupakan suatu kesatuan sistem yang terdiri atas Spatial System, Physical System, dan Stylistic System. Sistem model (stylistic system) ini meliputi fasade, bentuk pintu dan jendela serta unsur-unsur lain baik di dalam maupun di luar bangunan dari elemen atas (kepala), elemen tengah (badan), dan elemen bawah (kaki) di rumah tinggal tradisional Melayu dengan melihat nilai kekhasan yang unik dari fasade rumah tinggal rumah tinggal tradisional Melayu. Dalam penelitian terapan ini dapat digolongkan ke dalam skema sosial humaniora,seni budaya, Pendidikan dengan tema riset yaitu seni, identitas, kebudayaan, dan karakter bangsa. Sedangkan jika disesuaikan dengan Rencana Induk Penelitian (RIP) Jurusan Teknik Arsitektur Politeknik Negeri Pontianak tahun 2020-2024 judul penelitian terapan ini dapat dikelompokan menjadi 2 (dua) yaitu: a.) fokus penelitiannya : seni dan budaya dengan topik penelitian : tipomorfologi bangunan budaya dan bangunan bersejarah di Kalimantan Barat; b.) fokus penelitiannya : infrastruktur dan transportasi dengan topik penelitian : tipomorfologi perumahan ditepian air. Penelitian terapan ini menggunakan pendekatan metode rasionalistik-kualitatif dengan mengambil beberapa sampel penelitian dari populasi rumah tinggal tradisional Melayu ditepian sungai Kapuas yang masih ada dan masih bertahan sampai saat ini. Dalam penelitian ini menggunakan beberapa tahapan proses pelaksanaan yaitu : tahap pengumpulan data (observasi awal, observasi lanjutan, dan wawancara) dan tahap analisis data serta pembahasan hasil penelitian. Hasil yang ingin dicapai dari penelitian terapan ini adalah teridentifikasinya jenis/tipe/tipologi fasade rumah tinggal tradisional Melayu yang berada di tepian sungai Kapuas, Kampung Tambelan Sampit, kota Pontianak dengan dokumentasi data gambar (blue print), artikel ilmiah yang dimuat di jurnal maupun di prosiding nasional atau lokal.

Abstract

Penelitian ini menganalisis makna simbolis ornamentasi pada rumah tradisional Melayu dengan menggunakan pendekatan semiotika triadik Peirce. Tujuannya adalah untuk mengeksplorasi bagaimana elemen dekoratif merepresentasikan identitas budaya Melayu dan pengaruh nilai-nilai Islam. Data dikumpulkan melalui observasi lapangan, dokumentasi visual, dan wawancara dengan pemilik rumah tradisional. Hasil penelitian mengidentifikasi lima kategori motif utama flora, fauna, alam, kaligrafi, dan geometris yang masing-masing mengandung nilai-nilai budaya dan religius. Temuan menunjukkan bahwa ornamentasi tidak hanya memperkaya estetika arsitektur, tetapi juga memainkan peran penting dalam melestarikan nilai sosial, spiritual, dan identitas komunitas Melayu. Penelitian ini menawarkan wawasan penting tentang bagaimana motif tradisional dapat diadaptasi dalam konteks modern untuk menjaga relevansi budaya di tengah arus globalisasi. Semiotic Analysis of Ornamentation in Traditional Malay Houses: The Influence of Islamic Culture and Malay CustomsAbstractThis study analyzes the symbolic meaning of ornamentation in traditional Malay houses using Peirce's triadic semiotic approach. The aim is to explore how decorative elements represent Malay cultural identity and Islamic values. Data were collected through field observation, visual documentation, and interviews with traditional house owners. The findings identify five main motif categories flora, fauna, nature, calligraphy, and geometric patterns each embodying cultural and religious values. Results show that ornamentation not only enriches architectural aesthetics but also plays a vital role in preserving social, spiritual, and communal identity within Malay communities. This research provides valuable insights into how traditional motifs can be adapted in modern contexts to maintain cultural relevance amid globalization.

Abstract

mortality rates. This study aims to analyze and compare the performance of two machine learning algorithms—Random Forest and Gradient Boosting Machine (GBM)—in predicting heart disease risk based on patient medical data. A quantitative approach was used, incorporating Exploratory Data Analysis (EDA), data preprocessing, modeling, and evaluation using metrics such as accuracy, precision, recall, and F1-score. The dataset was obtained from Kaggle and included clinical attributes such as age, gender, blood pressure, cholesterol level, and chest pain type. The results show that both algorithms achieved high classification performance, with GBM outperforming overall, achieving 98.3% accuracy, 97.4% precision, 99.4% recall, and 98.4% F1-score. Meanwhile, Random Forest demonstrated strong performance with an accuracy of 94.7%. The most influential features in prediction were ST slope, oldpeak, and chest pain type. This study concludes that the application of GBM is more effective in supporting early heart disease detection and can serve as a fast, accurate, and efficient decision support system in healthcare settings with limited computational resources.

Abstract

The snapper species Lutjanus gibbus (L. gibbus) is commonly found in coastal areas characterized by coral reefs and clear water, while Lutjanus johnii (L. johnii) resides in mangrove waters with murky conditions and strong currents. The habitat plays a crucial role in influencing body shape and ossification patterns in fish. Therefore, this study aimed to examine the differences in the cranial bone morphology between the two Lutjanus fish species that resided in contrasting habitats. The fish samples were collected from local fishermen operating in the waters of Pulo Aceh, Aceh Besar, Indonesia. Following capture, the fish were transported and landed at Lampulo Fishing Port in Banda Aceh for further analysis. For each species, a total of 5 fish samples were randomly selected, and thorough cleaning of scales and muscles was performed before the drying of the bones. These dried cranial bones were then photographed, edited, and subjected to detailed analysis. The study showed that, of the 23 observed skull bone characters, 15 characters showed the differences in the cranial bones of the two snapper species, including the pre-ethmoidal, ethmoidal lateralis, prefrontal, supraorbital, nasal, ethmoidal, sphenoticum, crista occipital, lacrimal, inter-opercular, opercular, preopercular premaxilla, endopterygoideum, and hyomandibular. Significant differences were observed in the bones composing the eyes, nose, jaws, and ventral region of the head. In the mangrove snapper (L. johnii), the bones associated with the eyes (orbitospenoidal, supraorbital, and prefrontal) were less developed, while those related to the nose (nasal, ethmoidal, ethmoidal lateralis, pre-ethmoidal) showed well-developed characteristics. The coral snapper L. gibbus displayed a relatively small but thicker premaxilla bone in the jaw region, along with smaller bones in the ventral head area.Keywords:OsteologyMorphologyEcomorphologyOsteocraniumMaxillare

Abstract

Abstract : Changes in prospective students interest in majors university occur dynamically over time, requiring a forecasting method capable of accurately predicting interest trends. This study aims to apply the Double Exponential Smoothing (DES) method to predict the number of prospective students. The research employs a quantitative descriptive-analytical approach using secondary data on student interest from 2023 to 2025. The forecasting process is conducted using smoothing parameters for level (α) and trend (β), both set at 0.9. Furthermore, the accuracy of the forecasting model is evaluated using Mean Absolute Deviation (MAD), Mean Squared Error (MSE), and Mean Absolute Percentage Error (MAPE). The results indicate that the Double Exponential Smoothing method is effective in capturing the downward trend in student interest. The forecasted number of prospective students for 2026 is estimated at 462 students. Accuracy evaluation yields a MAD value of 98, an MSE of 19,208, and a MAPE of 18.63%, indicating that the forecasting error remains within an acceptable range. Therefore, the results of this study can be used as a supporting basis for strategic decision-making in planning new student admissions, strengthening promotional strategies, and managing academic resources.
