Judul: Perencanaan Lanskap Wisata Ekokultur Kampung Nelayan Muara Angke, Jakarta Utara
Abstrak: Kampung Nelayan Muara Angke, Jakarta Utara merupakan salah satu kawasan yang kaya akan potensi alam dan kearifan lokal. Namun, potensi tersebut mulai luntur karena pengembangan kawasan yang hanya berfokus pada segi ekonomi tanpa mempertimbangkan segi ekologi dan budayanya. Oleh karena itu, tujuan penelitian ini adalah menyusun rencana lanskap Kampung Nelayan Muara Angke, Jakarta Utara sebagai kawasan wisata berbasis ekokultur, yaitu suatu wisata berkelanjutan dengan mengkombinasikan prinsip-prinsip ekologi dan nilai lokal kawasan. Penelitian menggunakan pendekatan biofisik dan budaya. Analisis dan sintesis dari aspek biofisik, sosial dan budaya, serta potensi wisata menghasilkan zona pengembangan wisata. Konsep perencanaan yang dikembangkan adalah wisata ekokultur yang mencirikan Kawasan Muara Angke, yaitu kegiatan perikanan dan pengolahan ikan dengan mengkombinasikan aspek biofisik dan sosial budaya untuk meningkatkan kesejahteraan masyarakat lokal. Tiga ruang yang dikembangkan untuk mendukung wisata ekokultur di kampung nelayan ini adalah 24 ha ruang wisata ekokultur (61,5%), 12,75 ha ruang konservasi (32,7%), and 2,25 ha ruang pendukung wisata (5,8%).

Judul: Pengembangan Ekowisata di Mangrove Lindung Angke Kapuk. Jakarta Utara
Abstrak: Pengembangan ekowisata mangrove merupakan suatu cara untuk mendukung adanya konservasi lingkungan dan meningkatkan keikutsertaan masyarakat dalam mendukung kelestarian lingkungan agar mempertahankan keutuhan, keaslian, keunikan serta kelestarian suatu ekosistemnya. Penelitian ini bertujuan menganalisis kesesuaian ekosistem mangrove untuk ekowisata, menghitung daya dukung kawasan, dan merumuskan strategi pengembangan ekowisata Mangrove Lindung Angke Kapuk, Jakarta Utara. Metode penelitian yang digunakan, yaitu dengan survei/observasi lapangan. Pengambilan sampel kerapatan mangrove menggunakan metode petak contoh ganda yang dilakukan secara Purposive sampling yang mewakili. Beberapa fasilitas telah tersedia dan dapat dikembangkan untuk kegiatan seperti tracking mangrove, area duduk santai, dan memancing. Strategi pengelolaan kawasan ekowisata Mangrove Lindung Angke termasuk dalam kategori cukup baik, sehingga perlu dimaksimalkan strategi pengembangan ekowisata dengan memprioritaskan tiga alternatif strategi utama., The development of mangrove ecotourism is a way to support environmental conservation and increase community participation in supporting environmental sustainability in order to maintain the integrity, authenticity, uniqueness and sustainability of an ecosystem. This study aims to analyze the suitability of mangrove ecosystems for ecotourism, calculate the carrying capacity of the area, and formulate a strategy for developing ecotourism in the Mangrove Protected Angke Kapuk Ecotourism, North Jakarta. The research method used is survey/field observation. Mangrove density sampling was taken using a multiple sample plot method which was carried out by representative purposive sampling. Several facilities are available and can be developed for activities such as mangrove tracking, relaxing sitting areas, and fishing. The strategy for managing the Angke Protected Mangrove ecotourism area is in the fairly good category, so it is necessary to maximize the ecotourism development strategy by prioritizing three main strategic alternatives.

Judul: Enhancement of photon absorbtion on BaxSr1-xTiO3 thin films semiconductor using photonic crystals.
Abstrak: In this research, has been conducted BaxSr1-xTiO3 (BST) thin films manufacturing for mole fraction x = 0.25, 0.35, 0.45, and 0.55; and concentration of 1 molar using chemical solution depositon (CSD) method. The materials, which are used in this research, are barium acetate [Ba(CH3COO)2, 99%], strontium acetate [Sr(CH3COO)2, 99%], titanium isopropoxide [Ti(C12O4H28), 97.999%], gallium trioxide [Ga2O3], 2-methoxyethanol [H3COOCH2CH2OH, 99%] and 1 x 1 cm of transparent conductive oxide (TCO) glass as substrate. Two BST thin films are made that for BST thin films which are doped by 10% galium (BGST) as p-type layer and pure BST solution as n-type. BST solution is made by reacting barium acetate [Ba(CH3COO)2, 99%], strontium acetate [Sr(CH3COO)2, 99%] and titanium isopropoxide [Ti(C12O4H28)] into 2-methoxyethanol solvent [H3COOCH2CH2OH, 99%] in accordance with mass gram for each x value. While, BGST solution is made in the same way as BST solution, plus adding gallium at 10% of the mass of BST. Once all materials are reacted, then vibrated using ultrasonic for 90 minutes, and followed by coating BGST / BST on the TCO substrate. Once the layer is formed, then annealed for 15 hours at temperature of 500 °C with increasing rate of 1.67 oC/minute. Characterizations of BST thin films with or without photonic crystals include the absorbance and transmittance in the visible light spectrum, as well as the electrical photoconductivity characterizations. From BST thin films without photonic crystals indicate that our thin films have light absorption area on almost the entire range of the visible light spectrum even to the infrared range with absorption value over than 67.6%, in addition, it can be seen that the maximum absorbance of BST thin films for all mole fractions lie in blue to green light spectrum region, 457 nm ≤ λ ≤ 570 nm and the minimum in yellow to red light spectrum region, 570 nm ≤ λ ≤ 678 nm. The largest absorbance is found at x = 0.25 with average absorbance value of 92.04% and maximum and minimum absorbance peaks at wavelength of 500.89 and 657.72 nm, respectively. At x = 0.35, average absorbance value decreased to 83.55% with maximum and minimum peaks at 505.73 and 613.68 nm, respectively. Then increased to 91.16% at x = 0.45 with maximum and minimum peaks at 506.04 and 618.56 nm, respectively. At x = 0.55, average absorbance value decreased to 80.12% with maximum and minimum peaks at 507.85 and 608.79 nm, respectively. Moreover, it can be seen that the addition of barium mole fraction leads to wider maximum absorbance or minimum transmittance peaks and narrower minimum absorbance or maximum transmittance peaks in the same range of the green and blue & red light spectrums, respectively. BST thin films with photonic crystals show increasing in absorption for all x values in the range of 3.04 into 13.33%. At x = 0.25, average absorbance percentage increased 3.96% from 92.4 into 95.68%, for x = 0.35 average percentage increased 7.07% into 89.45 from 83.55%. Furthermore, average absorbance of BST thin films at x = 0.45 increased 3.04% from 91.16 into 93.93% and x = 0.55 has
