An Intelligent System for Predicting Breast Cancer (ISPBC) using a Novel Feature Selection Technique
Get PDFBreast cancer (BC) is becoming a global epidemic, largely affecting women. Breast cancer cases keep climbing steadily. Thus, early detection technologies or systems that notify patients to this disease are essential. Individuals can start treatment for this life-threatening illness, so that patients may be cured or given longer lives. To achieve this, in this study, an expert intelligence system named Intelligent System for Predicting Breast Cancer (ISPBC) was developed. The proposed system utilizes an innovative feature selection technique known as Enriched Feature Set (EFS) in order to identify the most appropriate and significant features. The proposed EFS employs the advantages of heuristic search techniques and stochastic hill climbing to select the most significant and important features. The Decision Tree and Random Forest techniques are employed for breast cancer diagnosis, distinguishing between malignant and benign types. The suggested model’s performance was evaluated by comparing measures such as accuracy, precision, and recall through the utilization of tenfold cross-validation. To measure the efficacy of the suggested model, ISPBC’s performance was compared to that of base classifiers and models published in the literature. A maximum accuracy of 96.09% was attained by ISPBC according to the results
Community Participation in Sustainable Cultural Heritage Tourism in The Braga Tourism Village
Get PDFThis study aims to examine community participation in the development of sustainable cultural heritage tourism in Braga Tourism Village, Bandung City. Initiated by the Bandung City Office of Culture and Tourism (DISBUDPAR) through a top-down approach as part of a tourism village activation program, the implementation of this initiative has raised concerns regarding the limited involvement of local residents. A descriptive qualitative approach was employed, with data collected through document analysis, field observations, and in-depth interviews with key stakeholders including street vendors, tourism awareness groups, village officials, and representatives of the local tourism office. Data were analyzed using Miles and Huberman’s interactive model through data reduction, display, and conclusion drawing. The findings reveal that while the initial planning was government-driven, local communities have gradually taken the lead in sustaining tourism activities by initiating creative and community-based programs. Public facilities and government-provided training have supported tourism development, yet the optimization of these resources remains limited due to insufficient community capacity. Moreover, the preservation of cultural heritage particularly Braga’s historic buildings and urban identity has been maintained through a combination of formal regulations and civic engagement. The study concludes that the success of sustainable tourism in urban heritage settings such as Braga depends on effective collaboration between government and communities, with local residents playing a central role in preserving cultural values while deriving socio-economic benefits.Partisipasi masyarakat sangat penting dalam pariwisata berbasis masyarakat (Community-based tourism/CBT). Strategi dalam bentuk fasilitas di Kampung Wisata Braga sudah cukup memadai untuk mencapai tujuan CBT. Kampung Wisata Braga dibentuk oleh Dinas Kebudayaan dan Pariwisata Kota Bandung dan memiliki potensi budaya dan Sejarah dengan pendekatan top-down yang memicu masalah karena perlunya partisipasi masyarakat yang lebih banyak dalam tahapan pengembangannya. Penelitian ini menggunakan metode kualitatif deskriptif untuk menyajikan data, menganalisis, dan mendeskripsikan partisipasi masyarakat di Kampung Wisata Braga. Pengumpulan data dilakukan dengan studi dokumen, wawancara mendalam dan observasi. Penemuan dari penelitian ini mengungkapkan strategi yang sudah berjalan yaitu beberapa kelompok masyarakat yang sudah berinisiatif untuk memajukan kawasan ini dengan kegiatan pariwisata. Strategi lain untuk mengembangkan Kawasan ini adalah dengan adanya fasilitas umum yang dapat digunakan wisatawan dan fasilitas pendukung. Ada juga fasilitas yang didukung oleh perusahaan dengan program tanggung jawab sosial perusahaan, namun beberapa fasilitas harus digunakan secara optimal. Program yang dilakukan untuk mendukung pariwisata oleh Dinas Pariwisata dan Kebudayaan Kota Bandung adalah pelatihan untuk masyarakat Kampung Wisata Braga. Namun, hal tersebut perlu dioptimalkan karena masyarakat belum memiliki pengetahuan cukup tentang pariwisata. Selain itu permasalahan dalam pengembangan adalah pendanaan untuk mengembangkan kawasan ini. Penelitian ini juga menunjukkan bahwa kelompok masyarakat Kelurahan Braga secara mandiri telah menjalankan program-program untuk pariwisata Kampung Wisata Braga sebelum adanya pendampingan dari Dinas Pariwisata dan Kebudayaan Kota Bandung, meskipun masih belum optimal karena masyarakat perlu mendapatkan pengetahuan dasar tentang pariwisata
Density Functional Theory Investigation on Muon Hyperfine Interaction in Methylated Guanine-Cytosine Double-Strand DNA
Get PDFThe aims of this study were to determine the most likely Mu trapping sites based on total energy consideration as well as identifying the associated muon hyperfine coupling constant of 1, 2, and 3 methylated guanine-cytosine base pair double-strand DNA. The Density Functional Theory method was used at B3LYP/6-31G level of theory to accomplish the objectives of the investigation. The relative energy in the 3 methylated guanine-cytosine base pair double-strand DNA molecule showed that N7 sites in the guanine base have the lowest energy, followed by N3, and C8 sites. It was found that the addition of a methyl group at the C5 atom in the cytosine base does change the stability of the C8 sites in the 3 methylated guanine-cytosine base pair double-strand DNA molecule, but the associated muon hyperfine coupling constant (HFCC) is not affected. The results of this study indicate that there will be no overlaps in the resonance dips due to N7, N3, and all C8 sites of the guanine bases and N3, C5, and C6 sites of the cytosine bases in the Avoided Level Crossing Muon Spin Resonance spectrum
KOMODIFIKASI PERKEMBANGAN KREATIVITAS SEBAGAI UPAYA STRATEGI BRANDING LEMBAGA SEKOLAH SENI ANAK
Get PDFThis branding study focuses on the process of commodification at Ganara Art Studio, a non-formal art institution. The analysis is conducted at two levels. Firstly, at the commodification level, it explores how creative learning practices at Ganara Art Studio can be understood through Piaget's theory of child development. Secondly, at the branding level, the study examines the broader context, specifically how Ganara Art is positioned in social and commercial relations. By addressing these two levels, a comprehensive understanding of children's education at Ganara Art is obtained, encompassing not only its pedagogy but also how the pedagogy operates within a broader social context: encompassing South Jakarta, prestige, and urban parents. This research is undertaken as a branding strategy study, emphasizing how the brand highlights the holistic experience provided by Ganara Art to students aged 3-4 years and urban parents. This study is supported by the theory of Experiential Branding, focusing on sensory, emotional, cognitive, and relational aspects. The research was carried out using a descriptive qualitative approach, and data was collected through interviews with the main subject being the founder of Ganara.Kajian branding ini tentang proses komodifikasi dalam konteks Ganara Art Studio sebagai lembaga seni non-formal. Analisis ini bergerak di dua tingkatan. Pertama, pada tingkat komodifikasi, diperiksa bagaimana praktik belajar kreatif di Ganara Art Studio dapat didekati melalui teori Piaget tentang perkembangan anak. Kedua, pada tingkat branding, peneliti melihat konteks yang lebih luas lagi, yakni bagaimana kedudukan Ganara Art dalam konteks relasi sosial dan komersial.

Sustainable Tourism through the Tri Hita Karana Concept
Get PDFThis study examines how the implementation of the Tri Hita Karana (THK) concept can support sustainable tourism. The participants for this study were selected using a purposive sampling technique. Data collection was conducted through observations and interviews. The data analysis method employed qualitative research techniques, including transcription, data reduction, data presentation, and drawing conclusions. The results of this study reveal that Anantara Uluwatu Bali Resort has successfully implemented the THK concept, as evidenced by the fulfillment of all indicators related to Parhyangan, Pawongan, and Palemahan. However, several indicators within the Pawongan and Palemahan aspects have not been fully optimized. These include the relationship between internal employees and management within the hotel, as well as the company's involvement in environmental conservation efforts. Based on these findings, this research suggests that further development of the Pawongan (human) and Palemahan (environmental) aspects is necessary to support sustainable economic, social, cultural, and environmental tourism
Identifying Effective Halal Attributes for Muslim Tourists in Japan: Perspectives from Supply and Demand
Get PDFHalal tourism is growing for Muslim and non-Muslim destinations due to Muslim population growth. Halal tourism is harder in non-Muslim countries due to cultural differences. Previous research investigated halal attributes from the perspective of the demand side. This study investigated Japan's halal attributes from the perspectives of supply and demand, as perceived by destination Muslim residents and Muslim tourists, thereby promoting halal tourism in non-Muslim destinations. The viewpoints of Muslim residents identified four important halal attributes: supportive infra and service, social environment, halal food and beverage, and specific facilities and amenities. The effectiveness of these attributes was confirmed by 253 Muslim tourists. It was found that the success of a non-Muslim destination in halal marketing is contingent on partial halal resources and well-managed indigenous resources
Dampak Perubahan Garis Pantai terhadap Status Titik Dasar dan Garis Pangkal Indonesia: Studi Kasus Nias Utara, Pulau Wunga, dan Bireun, Indonesia
Get PDFBeach is a very dynamic environment because, in that environment, various processes occur, such as sedimentation, abrasion, and transportation. Likewise, the shoreline has a dynamic nature to change. Shoreline Changes can affect a country's maritime boundaries. This is because the changing shoreline can change the draw of the Baseline, which is the reference for measuring the maritime boundary. Therefore, it is necessary to monitor the shoreline where the Basepoint and Baseline are located. In this study, measurements of shoreline changes were made using SPOT 6 data which has a spatial resolution of 1.5 m. Shoreline changes were calculated using the DSAS. From the calculation results, the average rate of accretion in the Base Point 167 area is 5.63 m/year. Then in the area around Base Point 168 it has an average accretion rate of 2.27 m/year. In the area around Base Point 180, an average accretion rate of 15.11 m/year is obtained. The accretion process results in a change in the shoreline, resulting in a change in the configuration of the low water line which is the location where the base point is placed. Thus, changes in the shoreline can affect the withdrawal of Indonesia’s maritime boundaries.Pantai adalah lingkungan yang sangat dinamis karena dalam lingkungan tersebut, berbagai terjadi proses seperti sedimentasi, abrasi, dan transportasi. Demikian pula, garis pantai memiliki sifat dinamis yang berubah-ubah. Perubahan garis pantai juga dapat memengaruhi batas laut suatu negara. Hal ini karena perubahan garis pantai dapat mengubah tata letak garis pangkal, yang merupakan acuan untuk mengukur batas laut negara. Oleh karena itu, penting untuk memantau garis pantai di tempat titik dasar dan garis pangkal berada. Perubahan garis pantai dalam penelitian ini diukur menggunakan citra satelit SPOT 6 yang memiliki resolusi spasial 1,5 meter. DSAS digunakan sebagai alat untuk mengukur perubahan garis pantai. Dari hasil perhitungan, rata-rata laju akresi di area Titik Dasar 167 adalah 5,63 m/tahun. Rata-rata laju akresi di sekitar Titik Dasar 168 tercatat sebesar 2,27 meter per tahun. Laju pertumbuhan garis pantai di sekitar Titik Dasar 180 mencapai rata-rata 15,11 meter setiap tahunnya. Proses akresi mengakibatkan perubahan garis pantai, sehingga terjadi perubahan konfigurasi garis air rendah yang merupakan lokasi titik dasar ditempatkan. Dengan demikian, perubahan garis pantai dapat memengaruhi penarikan batas laut Indonesia
Potensi Emisi Gas Rumah Kaca dari TPA Galuga dan Kelayakan Finansial Teknologi RDF
Get PDFMany cities are confronting significant challenges due to the rising volume of waste. This surge in waste generation not only risks overcapacity but also contributes to increased greenhouse gas (GHG) emissions. This study aims to estimate the amount of waste directed to the Galuga landfill, evaluate the potential GHG emissions resulting from the landfill, and analyze the financial viability of implementing Refuse DerivedFuel (RDF) technology, which has the potential to reduce waste volumes. This research employs three key methods: 1) Multiple Linear Regression (MLR) to identify the factors that influence waste generation, 2) the IPCC guidelines for National Greenhouse Gas Inventories Volume 5 to estimate potential greenhouse gas emissions, and 3) a financial feasibility analysis to evaluate the viability of implementing RDF technology.The results show that the volume of waste directed to the Galuga landfill in 2022 was 195,787.10 tons, with a projected increase of 2.43% by 2030, bringing the total to 200,544.26 tons. The potential greenhouse gas (GHG) emissions from waste generated at the Galuga landfill are estimated to be 109 kt CO2e in 2030, reflecting a decrease of 29.48% compared to 2022. Furthermore, the plan to implement RDF technologyis deemed financially viable, as it fulfills the necessary criteria for Net Present Value (NPV), Internal Rate of Return (IRR), Benefit-Cost (B/C) Ratio, and Payback Period. Therefore, the governments may introduce various incentives to promote the adoption of RDF technology, stricter waste segregation is essential for better RDF quality, and attracting private investment through PPPs can enhance RDF infrastructure.Sejumlah kota menghadapi masalah serius akibat peningkatan volume sampah. Timbulan sampah yang terus meningkat berpotensi menyebabkan overcapacity, serta meningkatkan emisi gas rumah kaca (GRK). Penelitian ini bertujuan untuk mengestimasi timbulan sampah yang masuk ke TPA Galuga, potensi emisi GRK yang dihasilkan dari TPA Galuga, serta menganalisis penerapan teknologi RDF yang dapat mereduksi jumlah sampah. Penelitian ini menggunakan Multiple Linear Regression (MLR) untuk mengetahui faktor-faktor yang memengaruhi timbulan sampah, Guidelinesfor National Greenhouse Gas Inventories Vol.5 (Waste) untuk mengestimasi potensi emisi GRK TPA Galuga, serta analisis kelayakan finansial untuk mengetahui kelayakan penerapan teknologi RDF. Hasil penelitian menunjukkan jumlah sampah yang masuk ke TPA Galuga tahun 2022 sebesar 195.787,10 ton dan meningkat 2,43% pada tahun 2030 menjadi 200.544,26 ton. Potensi emisi GRK dari timbulan sampah TPA Galuga berkisar 109 kt CO2e pada tahun 2030, turun 29,48% dari tahun 2022. Rencana penerapan teknologi RDF layak dijalankan secara finansial karena memenuhi kriteria kelayakan NPV, IRR, B/C Ratio, dan Payback Period. Oleh karena itu, pemerintah dapat memberikan berbagai insentif untuk mendorong penerapan teknologi RDF,pemilahan sampah yang lebih ketat sangat penting untuk meningkatkan kualitas RDF, dan menarik investasi swasta melalui kemitraan pemerintah dan swasta dapat meningkatkan infrastruktur RDF
Spatial Knowledge: A Tool for Community Planning and Addressing Environmental Issues in Regional Context?
Get PDFThis study investigates the implementation of participatory mapping activities with indigenous communities to uncover their spatial understanding of environmental issues in regional context. By combining participatory GIS with a phenomenological approach, the research aims to extract critical environmental concerns and develop prioritization schemes for planning and conservation efforts, particularly in forest and small island communities. Two case studies were conducted: the Orang Rimba community in Jambi, Indonesia, and the Lovongai community in New Ireland Province, Papua New Guinea. Workshops and training sessions were held with small group in each community to identify and discuss local environmental challenges. The study revealed that the Orang Rimba community primarily concerns the decline of medicinal plant species and the threat on animal habitats, while the Lovongai community faces the pressing threat of sea-level rise. Through participatory mapping and collaborative efforts with local governments and NGOs, both communities developed potential solutions to address their respective environmental issues. It is recommended that future studies explore the long-term impacts of participatory mapping initiatives on community empowerment, environmental stewardship, and sustainable development
