Pemetaan Curah Hujan Menggunakan Inverse Distance Weighting (IDW) Untuk Mengurangi Risiko Bencana Hidrometeorologi di Kota Denpasar
Full text linkAbstrak
Indonesia baru-baru ini menghadapi serangkaian bencana hidrometeorologi, termasuk banjir. Untuk mengurangi dampak dari kejadian tersebut, salah satu pendekatan yang efektif adalah mengembangkan peta yang menampilkan tingkat curah hujan maksimum bulanan. Peta ini dapat dibuat menggunakan sistem informasi geospasial, seperti ArcGIS, dengan teknik interpolasi seperti Inverse Distance Weighted (IDW). Berdasarkan analisis hidrologi dan interpolasi IDW, penelitian menemukan bahwa Kota Denpasar mengalami variasi intensitas curah hujan: hujan ringan (7-20 mm), hujan sedang (20-50 mm), dan hujan lebat (50-95 mm). Curah hujan tertinggi tercatat pada bulan Januari. Analisis visualisasi rancangan curah hujan mengungkapkan bahwa curah hujan harian maksimum untuk periode ulang 2 tahun berkisar antara 125-134 mm, terjadi di seluruh wilayah Denpasar kecuali Denpasar Selatan. Untuk periode ulang 5, 10, 15, 20, 25, dan 50 tahun, kisaran curah hujan harian maksimum masing-masing adalah 169-185 mm, 205-228 mm, 218-245 mm, 228-262 mm, 249-281 mm, dan 295-338 mm. Puncak hujan terfokus di Denpasar Barat dan Denpasar Selatan. Identifikasi daerah rawan banjir di Kota Denpasar menunjukkan bahwa risiko banjir tidak hanya bergantung pada curah hujan, tetapi juga dipengaruhi faktor antropogenik seperti perubahan tata guna lahan, sehingga diperlukan pembaruan peta risiko berbasis data spasial untuk mitigasi yang lebih efektif.

Abstract
Indonesia has recently faced a series of hydrometeorological disasters, including flooding. To mitigate the impacts of these events, one effective approach is to develop maps that display maximum monthly rainfall levels. These maps can be created using geospatial information systems, such as ArcGIS, with interpolation techniques like Inverse Distance Weighted (IDW). Based on hydrological analysis and IDW interpolation, the study found that the city of Denpasar experienced variations in rainfall intensity: light rain (7-20 mm), moderate rain (20-50 mm), and heavy rain (50-95 mm). The highest rainfall was recorded in January. The visual analysis of rainfall design reveals that the maximum daily rainfall for a 2-year return period ranges from 125-134 mm, occurring throughout Denpasar except for South Denpasar. For return periods of 5, 10, 15, 20, 25, and 50 years, the ranges of maximum daily rainfall are 169-185 mm, 205-228 mm, 218-245 mm, 228-262 mm, 249-281 mm, and 295-338 mm, respectively. The peak rainfall is concentrated in West Denpasar and South Denpasar. The identification of flood-prone areas in Denpasar City shows that flood risk is not only dependent on rainfall, but is also influenced by anthropogenic factors such as land use changes, thus requiring updates to risk maps based on spatial data for more effective mitigation.

Rancang Bangun Sistem Adaptive Cruise Control (ACC) dengan Metode Fuzzy Logic pada Prototype Robo Car
Full text linkThe rapid growth of four-wheeled vehicles in Indonesia has contributed to an increase in traffic accidents, where human error is a significant factor. Adaptive Cruise Control (ACC) is a technology that has been widely implemented in Advanced Driver Assistance Systems (ADAS) to improve driving safety. This study develops a Fuzzy Logic Controller (FLC)-based ACC system using ESP8266 as the main microcontroller to optimize adaptive vehicle speed control based on the distance to the object in front. This system is designed to process distance and speed data in real-time, allowing it to adjust the vehicle's speed without sudden changes. A fuzzy logic model was developed and validated through MATLAB simulations before being implemented into hardware. Test results indicate that the FLC-based ACC system can maintain a safe distance and dynamically regulate speed, exhibiting smoother speed transitions compared to conventional methods. A comparison between MATLAB simulation results and real-world implementations shows that the system can operate with high accuracy, despite differences due to environmental factors. With this success, this research proves that FLC can be a more flexible alternative in ACC systems and has the potential to be applied in the development of electric and autonomous vehicles in the future.Pertumbuhan jumlah kendaraan roda empat di Indonesia yang pesat telah berkontribusi pada peningkatan angka kecelakaan lalu lintas, di mana kesalahan manusia menjadi faktor utama. Adaptive Cruise Control (ACC) merupakan teknologi yang telah banyak diterapkan dalam sistem bantuan pengemudi (Advanced Driver Assistance Systems/ADAS) untuk meningkatkan keselamatan berkendara. Penelitian ini mengembangkan sistem ACC berbasis Fuzzy Logic Controller (FLC) menggunakan ESP8266 sebagai mikrokontroler utama, dengan tujuan mengoptimalkan pengendalian kecepatan kendaraan secara adaptif berdasarkan jarak terhadap objek di depannya. Sistem ini dirancang untuk mengolah data jarak dan kecepatan secara real-time, sehingga dapat menyesuaikan kecepatan kendaraan tanpa perubahan yang tiba-tiba. Model fuzzy logic dikembangkan dan divalidasi melalui simulasi MATLAB sebelum diimplementasikan ke dalam perangkat keras. Hasil pengujian menunjukkan bahwa sistem ACC berbasis FLC mampu menjaga jarak aman dan mengatur kecepatan secara dinamis, dengan transisi kecepatan yang lebih halus dibandingkan metode konvensional. Perbandingan antara hasil simulasi MATLAB dan implementasi nyata menunjukkan bahwa sistem dapat beroperasi dengan akurasi tinggi meskipun terdapat perbedaan akibat faktor lingkungan. Dengan keberhasilan ini, penelitian ini membuktikan bahwa FLC dapat menjadi alternatif yang lebih fleksibel dalam sistem ACC dan memiliki potensi untuk diterapkan dalam pengembangan kendaraan listrik dan otonom di masa depan
Norma dan Negosiasi dalam Fandom Plave Indonesia di X
Full text linkIn virtual idol fandoms, fans often follow shared norms that shape how they interact with one another. This research draws on fandom, norms, and negotiation theories to explore how such norms emerge and are negotiated within the Plli fandom on social media X, focusing on the figure of “Terra Plave” as the controlling presence behind Plave’s virtual idol avatar. Based on data from phenomenological interviews with four Indonesian fans, the study identifies two central aspects of these norms: the types of accounts fans use and their responses to provocative posts and doxxing. The findings suggest that the norms surrounding Terra Plave reflect an ongoing process of negotiation among fans, aimed at resolving internal conflicts triggered by official statements from Plave’s label.Dalam fandom idola virtual, penggemar sering mengikuti norma-norma bersama yang membentuk cara mereka berinteraksi dengan satu sama lain. Penelitian ini mengacu pada teori fandom dan teori norma untuk mengeksplorasi bagaimana norma-norma tersebut muncul dan dinegosiasikan dalam fandom Plli di media sosial X, dengan fokus pada figur “Terra Plave” sebagai sosok pengendali dibalik avatar idola virtual Plave. Berdasarkan data wawancara fenomenologi terhadap empat orang penggemar Indonesia, penelitian ini mengidentifikasi dua aspek utama dari norma-norma tersebut, yaitu jenis akun yang digunakan penggemar dan tanggapan mereka terhadap unggahan provokatif dan doksing. Temuan penelitian ini menunjukkan norma seputar Terra Plave mencerminkan proses negosiasi yang sedang berlangsung di antara para penggemar, ditujukan untuk menyelesaikan konflik internal yang dipicu oleh pernyataan resmi dari label yang menaungi Plave

Using a case study approach, this research combined field observations, in-depth interviews with key stakeholders, and analysis of policy and spatial planning documents. Key innovations highlighted in this study were: ecological zoning, adaptive reuse of heritage structures, engagement with local artisans, and the implementation of renewable energy systems. The findings reveal that these interventions not only enhance environmental performance and spatial quality but also strengthen cultural identity and foster community participation. This study contributes a replicable model for heritage-based tourism revitalization in developing countries, particularly in Southeast Asia, by integrating global sustainability principles with the Balinese local philosophy of Tri Hita Karana. The proposed model offers both a theoretical contribution to the literature on urban regeneration and a practical reference for planners, architects, and policymaker
Identification of Community-Based Football Activities in Yogyakarta: A Philosophical Review
Full text linkFootball is not always professional and is not entirely competitive or achievement-
oriented. Football can also be carried out as a recreational activity. Community-
based football, more familiarly known as fun football, represents football activities
that are recreational in nature. This study aims to identify the philosophical values
contained in community-based football activities in Yogyakarta. Using a
qualitative-philosophical approach (ethnography, phenomenology, hermeneutics),
this study explores how community football is not only understood as a physical
activity but also as a medium for reflecting humanistic values, solidarity, and local
identity. Data were collected through participatory observation, in-depth
interviews with respondents (consisting of players, coaches, team administrators,
and field managers), as well as text analysis from relevant documents. The research
results show that community football in Yogyakarta contains philosophical values
such as mutual cooperation, togetherness, and happiness. This activity also serves
as a space for negotiation between local traditions and modernity, which can have
a positive impact on the sports tourism sector. The study concludes that community-
based football in Yogyakarta is a social practice rich in philosophical meaning, as
well as a form of resistance to the commercialization of sports.

SFHAM has proven to be an effective approach for local food security in urban areas when supported by continuous mentoring and active community participation. Evaluation and monitoring indicate the need for continuous mentoring and adaptation of methods to local conditions to ensure the sustainability of the program. Thus, the implementation of SFHAM is expected to support local food security, improve family economics, and contribute to sustainable environmental management in urban areas
Bauxitization and REE Redistribution in Weathered I-type Granite Profile of Gunung Kijang, Bintan Island
Full text linkWeathering is often linked to economic mineral enrichment, including nickel, bauxite, and rare earth elements (REE). The exposed granitic rocks on Bintan Island, Riau Islands Province, belong to the Southeastern Asian Eastern Granite Province. This study examines the bauxitization process and REE distribution across weathered granite horizons in the Gunung Kijang area. Major oxides were analyzed using X-ray fluorescence, while trace and rare earth elements were determined by inductively coupled plasma–mass spectrometry. The trace element composition and metaluminous nature of the parent granite confirm its I-type classification. Kaolinization and bauxitization were observed in the weathered layers, with Al₂O₃ and Fe₂O₃T contents ranging from 25.21–46.50% and 6.99–8.76%, respectively. Total REE content in the weathered horizons (up to 76 ppm) is lower than in the parent rock (214 ppm). Nevertheless, the soft, near-surface materials offer potential for future REE utilization. Clay minerals are the main REE hosts, while the enrichment from the C-horizon upward is influenced by higher organic matter near the surface. Similar Eu and Ce anomaly patterns indicate minimal feldspar in the original granite or limited feldspar breakdown during weathering
