No full textPEMANFAATAN CITRA PENGINDERAN JAUH MULTI-TEMPORAL UNTUK DETEKSI URBAN HEAT ISLAND (UHI) TERHADAP PERUBAHAN PENGGUNAAN LAHAN DI KABUPATEN BULELENG
No full textFenomena Urban Heat Island (UHI) sering dipengaruhi oleh kepadatan penduduk dan perubahan penggunaan lahan. Perubahan tesebut memiliki hubungan dengan peningkatan suhu permukaan (Land Surface Temperature/LST) sebagai awal terjadinya UHI. Deteksi perubahan penggunaan lahan dan suhu permukaan dilakukan dari tahun 2000, 2010, dan 2018 pada daerah Kabupaten Buleleng dan berfokus di Kecamatan Buleleng karena memiliki perubahan lahan terbangun lebih cepat dibandingkan kecamatan lain. Tujuannya untuk mengetahui bagaimana fenomena UHI itu terjadi akibat dari perubahan penggunaan lahan. Selain itu, seberapa besar peningkatan suhu permukaan selama 18 tahun khususnya di Kecamatan Buleleng dengan mengetahui kondisi sebaran dan intensitas UHI. Metode yang digunakan dalam deteksi UHI menggunakan citra penginderaan jauh multi-temporal yaitu citra Landsat 7 ETM+ dan citra Landsat 8 OLI/TIRS (The Operational Land Imager and the Thermal Infrared Scanner) sebagai data primer. Pengolahan data akan berfokus pada ekstraksi suhu permukaan dengan metode Split-Windows Algorithm Sobrino (SWA-S) untuk Landsat 8 dan metode Brightness Temperature Emissivity Correction untuk Landsat 7, kemudian Maximum Likelihood sebagai metode deteksi perubahan penggunaan lahan. Hasil pengolahan menunjukkan bahwa perubahan penggunaan lahan memberikan dampak terhadap fenomena UHI. Perubahan penggunaan lahan dari tahun 2000 hingga 2018 terdapat peningkatan lahan terbangun di Kecamatan Buleleng dan peningkatan suhu permukan sebesar 2°-7°C dari lahan terbangun. Fenomena UHI untuk distribusi dan instensitas UHI terjadi di daerah pusat perkotaan dan kenaikan intensitas UHI sebesar 1.75°C. Kesimpulannya bahwa perubahan lahan terbangun memberikan dampak kenaikan suhu permukaan dan menyebabkan fenomena UHI

Evaluation of Community-Based Drinking Water Supply System Management in Ladogahar Village Sikka District East Nusa Tenggara
No full textThe Ladogahar Village Government established a Village Drinking Water Supply System (DWSS) to meet the water needs of its people. The Village Government gives responsibility to the community to manage the Village DWSS. Each hamlet has a person in charge of DWSS management. The clean water supply system in Ladogahar Village has several problems. One of them is that the existing community-based DWSS management has experienced a decline in performance in terms of technical, institutional, financial, and social aspects, so that water distribution is not optimal. Therefore, this study aims to evaluate Ladogahar DWSS so that problems with the it can be identified, assess the level of sustainability of DWSS management, and compile priority development factors so that village DWSS becomes more optimal. The method used in this study is to evaluate existing conditions and analyze community and stakeholder perceptions of the sustainability of village DWSS management. To determine the level of Drinking Water Supply System sustainability using the index formula, for important factors in DWSS sustainability using the Relative Importance Index (RII) and Confidence Interval (CI) tests, while compiling priority factors for DWSS development using the Development Priority Index (IPP). The results of the assessment of the sustainability of community-based DWSS management reviewed from technical, institutional, financial, and environmental aspects show sustainable results, while the social aspect shows sustainable results. Priority factors for development in community-based drinking water supply system management are the continuity of water received, the addition of public taps, manager performance, availability of raw water, service coverage, regularity of payment of fees, and quantity of water received. To create sustainable drinking water supply system management, various improvements and developments of DWSS are needed both from technical aspects (raw water units, distribution units, service units, quantity, continuity) and institutional aspects (institutions and finances).

Wavelet Transformation and Spectral Subtraction Method in Performing Automated Rindik Song Transcription
No full textRindik is Balinese traditional music consisting of bamboo rods arranged horizontally and played by hitting the rods with a mallet-like tool called "panggul". In this study, the transcription of Rindik's music songs was carried out automatically using the Wavelet transformation method and spectral subtraction. Spectral subtraction method is used with iterative estimation and separation approaches. While the Wavelet transformation method is used by matching the segment Wavelet results with the Wavelet result references in the dataset. The results of the transcription were also synthesized again using the concatenative synthesis method. The data used is the hit of 1 Rindik rod and a combination of 2 Rindik rods that are hit simultaneously, and for testing the system, 4 Rindik songs are used. Each data was recorded 3 times. Several parameters are used for the Wavelet transformation method and spectral subtraction, which are the length of the frame for the Wavelet transformation method and the tolerance interval for frequency difference in spectral subtraction method. The test is done by measuring the accuracy of the transcription from the system within all Rindik song data. As a result, the Wavelet transformation method produces an average accuracy of 83.42% and the spectral subtraction method produces an average accuracy of 78.51% in transcription of Rindik songs
