Judul: Dampak Ekonomi dan Daya Dukung Kawasan dalam Pengembangan Wisata Pulau Tidung, Kepulauan Seribu, DKI Jakarta
Abstrak: Tourism activities give an advantage in economic growth in some Indonesia areas, such as increasing income and opening job vacancy for local society. One areas that has potency in developing tourism sector is Tidung Island, DKI Jakarta. The tourism development was started in 2009, where the total tourism visiting Tidung Island is increasing every year. It has given a positive impact to the local economic. Economic impact from tourism activities were direct, indirect, and induce impact. Multiplier effect analysis method was used to analize economic impact in Tidung Island. Keynesian income multiplier value was 1.7 and ratio income multiplier type I and type II were 1.5 and 1.6. Moreover, the increasing of tourist number was potentially caused by over carrying capacity in some certain point areas in snorkeling and beach tourism, especially on peak season. So that, appropiate strategy is needed for managing and developing tourism area. Some alternative strategies that can be implemented for Tidung Island tourism management are: maintaining and increasing tourism management system; maintaining cooperation between management party, society, and tourist to protect resource and environment of tourism area; promoting new tourism; developing other potencial areas and new tourism activities to avoid over carrying capacity in some certain areas; increasing education and information to the society and tourist in maintaining the environment preservation, hygiene, and beauty of tourism area; and managing professionalism of local labor in tourism through training.

Judul: Analysis of the Ecotourism Potential of Coral  Reefs Around Tidung Island, Seribu Islands, Daerah Khusus Jakarta
Abstrak: Ekowisata terumbu karang yang terdapat pada Pulau Tidung memiliki potensi yang sangat besar. Namun, aktivitas ekowisata terumbu karang di Pulau Tidung memiliki beberapa permasalahan yang harus diatasi seperti perilaku wisatawan yang tidak bertanggung jawab, dan kebijakan pengelolaan yang belum optimal. Penelitian ini bertujuan untuk menganalisis potensi terumbu karang, mengetahui daya dukung, dan merancang strategi pengelolaan wisata bahari terumbu karang di Pulau Tidung, Kepulauan Seribu, Daerah Khusus Jakarta. Penelitian dilakukan pada bulan September hingga Desember 2023. Pengambilan data terkait terumbu karang dan ikan yang ada di terumbu karang dilakukan pada 9 titik area, diantaranya terdapat 3 area pada Pulau Tidung Kecil dan 6 area pada Pulau Tidung Besar. Pengambilan data wawancara terhadap wisatawan dilakukan di Pulau Tidung Besar. Analisis data yang digunakan dalam penelitian ini yaitu indeks kesesuaian ekowisata kategori wisata selam, daya dukung kawasan, dan analisis SWOT. Hasil yang diperoleh yaitu Pulau Tidung memiliki tutupan yang beragam, jenis lifeform yang paling banyak ditemukan yaitu Rubble, jenis ikan terdiri dari 9 famili, indeks kesesuaian yang menunjukkan beberapa wilayah yang sesuai dan tidak sesuai, dan kesesuaian beberapa area dengan daya dukung., Coral reef ecotourism on Tidung Island has enormous potential. However, coral reef ecotourism activities on Tidung Island have several problems that must be overcome, such as irresponsible tourist behavior, and management policies that are not yet optimal. This research aims to analyze the potential of coral reefs, determine their carrying capacity, and design strategies for managing coral reef marine tourism on Tidung Island, Seribu Islands, Daerah Khusus Jakarta. The research was carried out from September to December 2023. Data collection regarding coral reefs and fish on coral reefs was carried out at 9 stations, including 3 stations on Tidung Kecil Island and 6 stations on Tidung Besar Island. Data collection from interviews with tourists was carried out on Tidung Besar Island. The data analysis used in this research is the ecotourism suitability index for the diving tourism category, regional carrying capacity, and SWOT analysis. The results obtained are that Tidung Island has a variety of cover, the most common type of lifeform is Rubble, fish species consist of 9 families, a suitability index that shows several suitable and unsuitable areas, and the suitability of several stations with carrying capacity.

Judul: Application of Mel Frequency Cepstrum Coefficients (MFCC) as Feature Extraction on Phoneme Recognition with Probabilistic Neural Network (PNN) as Classifier
Abstrak: Voice recognition (speech recognition) is one field of study in voice processing. This technology can convert voice signals into a form of written information (text). With this technology, people can interact with a computer. MFCC feature extraction computes the cepstral coefficients by considering the human hearing. This research is a phoneme recognition using feature extraction MFCC and PNN as feature matching model. This study compares the coefficient, overlap, and the test data without noise and with noise. MFCC is used with 13, 20, 26 coefficients and 0%, 25%, 50% overlap. Noise is added by 30 dB, 20 dB and 10 dB. From the comparison of the three overlaps, produced the best accuracy at 50% overlap with an accuracy of 94,71%. From comparing the three coefficients, better accuracy resulting in coefficients of 20 and 26 with an accuracy of 97,12% at 50% overlap. After comparing between the coefficients of 20 and 26 with overlap of 25% then the coefficient 26 is obtained that better accuracy of 94,23%. This shows that in this study the coefficient 26 is the best. In this research, there are three noise variables. The variables are 10 dB, 20 dB, and 30 dB. The best accuracy reached when the noise variable is 30 dB rather than 10 dB or 20 dB because the accuracy has the closest accuracy compared by the accuracy when noise was not added into the data. When the noise variable is 30 dB, the percentage of accuracy is 85,3%.
