INDEKS KEPEKAAN LINGKUNGAN EKOSISTEM MANGROVE TERHADAP TUMPAHAN MINYAK: STUDI KASUS DI PESISIR SUBANG, JAWA BARAT

The mangrove ecosystem in Subang Coastal is potentially effected due to oil spills. The oil spill in this area can be caused by an accident of petroleum exploitation. Therefore, it needs to anticipate and plan comprehensively for environmental protection from oil spills. Environmental sensitivity index (ESI) analysis can be used to classify the level of sensitivity of the mangrove ecosystem to the oil spill. This study aims to calculate the ESI for mangrove ecosystems in Subang coastal areas. ESI was formed by combining the Vulnerability Index (VI), Ecological Index (EI), and Socio-economic Index (SI). Secondary data was collected by study literature. The primary data was conducted from 13 locations. The parameters in VI are coastal slope, tidal type, tidal range, wave height, substrate type, and mangrove distance from the coastline. The parameters in EI are mangrove zonation, mangrove density mangrove diversity, age of mangrove, protected species, and mangrove conservation status. The parameter in SI consists of social and economic components. The result showed that the mangrove ecosystem of the Subang coastal area has a sensitivity status from moderate to sensitive. Among 13 locations, only three locations were classification sensitive to the oil spill. The locations were Tegal Tike, Anggaranu, and Tanjung. Although the study areas are dominated by the moderate sensitivity category, however, the protection of the mangrove ecosystem from oil spills should be prioritized.Ekosistem mangrove di daerah pesisir Subang berpotensi terdampak oleh tumpahan minyak. Tumpahan minyak di daerah tersebut bisa bersumber dari kecelakaan pada kegiatan eksploitasi minyak bumi. Oleh karena itu, diperlukan antisipasi dan rencana yang komprehensif untuk melindungi lingkungan dari tumpahan minyak. Indeks Kepekaan Lingkungan (IKL) dapat digunakan untuk mengklasifikasi tingkat kepekaan ekosistem mangrove terhadap tumpahan minyak. Penelitian ini bertujuan untuk menghitung IKL ekosistem mangrove di daerah pesisir Subang. IKL dibentuk dari gabungan Indeks Kerentanan (IK), Indeks Ekologi (IE) dan Indeks Sosial ekonomi (IS). Data sekunder diperoleh dengan cara studi literatur, sedangkan pengambilan data primer dilakukan di 13 lokasi pengamatan. Parameter IK terdiri dari kemiringan pantai, tipe pasang surut, rentang pasang surut, tinggi gelombang, tipe substrat dan jarak mangrove dari bibir pantai. Parameter IE terdiri dari zonasi mangrove, kepadatan mangrove, keragaman mangrove, umur mangrove, keberadaan spesies dilindungi dan status konservasi mangrove. Parameter IS terdiri dari komponen sosial dan komponen ekonomi. Hasil penelitian menunjukkan bahwa ekosistem mangrove di pesisir Subang memiliki tingkat kepekaan dari cukup peka hingga peka. Dari 13 lokasi pengamatan, hanya 3 lokasi yang memiliki status peka terhadap tumpahan minyak. Daerah tersebut adalah Tegal Tike, Anggaranu, dan Tanjung. Walaupun tingkat kepekaan daerah pengamatan didominasi oleh kategori cukup peka, namun perlindungan ekosistem mangrove dari tumpahan minyak harus menjadi prioritas

Real Time Face Recognition Based on Face Descriptor and Its Application

This paper presents a real time face recognition based on face descriptor and its application for door locking. The face descriptor is represented by both local and global information. The local information, which is the dominant frequency content of sub-face, is extracted by zoned discrete cosine transforms (DCT). While the global information, which also is the dominant frequency content and shape information of the whole face, is extracted by DCT and by Hu-moment. Therefore, face descriptor has rich information about a face image which tends to provide good performance for real time face recognition. To decrease the dimensional size of face descriptor, the predictive linear discriminant analysis (PDLDA) is employed and the face classification is done by kNN. The experimental results show that the proposed real time face recognition provides good performances which indicated by 98.30%, 21.99%, and 1.8% of accuracy, FPR, and FNR respectively. In addition, it also needs short computational time (1 second)
