Judul: Regulasi Nelayan Andon dan Implementasinya di Muara Angke, Jakarta Utara
Abstrak: Andon adalah nelayan melakukan penangkapan ikan di luar wilayah administrasinya yang menggunakan kapal berukuran paling besar 30 gross tonnage dengan daerah penangkapan ikan sesuai dengan surat izin penangkapan ikan andon. Penelitian ini bertujuan untuk mendeskripsikan regulasi andon penangkapan ikan di Indonesia, menggambarkan implementasi andon penangkapan ikan di Muara Angke, dan merumuskan strategi terkait pengelolaan andon penangkapan ikan. Metode pengumpulan data yang digunakan, yaitu wawancara dan kuesioner. Hasil pengkajian Permen KP Nomor 25/Permen KP/2020 terdiri atas enam hal, yaitu batasan tonase kapal andon, landasan hukum mengenai kesepakatan dan perjanjian kerja sama, perizinan dan perpanjangan izin andon, surat tanda keterangan andon, sosialisasi andon, dan pelaporan hasil tangkapan ikan. DKI Jakarta melakukan perjanjian kerja sama dengan empat provinsi, namun estimasi potensi dan alokasi usaha belum diterapkan secara utuh, Dinas Ketahanan Pangan Kelautan dan Pertanian memberikan rekomendasi dan penerbitan izin andon oleh Dinas Penanaman Modal dan Pelayanan Terpadu Satu Pintu. Pengelolaan andon penangkapan ikan dapat dikembangkan melalui strategi memaksimalkan pelaksanaan kebijakan dengan memperhatikan sumber daya ikan agar tetap berkelanjutan.

Judul: Peluang Peningkatan Kelas Pangkalan Pendaratan Ikan Muara Angke, Jakarta Utara
Abstrak: Aktivitas produksi dan transaksi hasil perikanan meningkat cukup pesat terlihat dari produksi ikan yang didaratkan, serta kapal-kapal penangkapan ikan yang berukuran diatas 30 GT melakukan bongkar muat di Pangkalan Pendaratan Ikan (PPI) Muara Angke, hal ini diperlukan upaya pengembangan untuk menunjang kegiatan perikanan. Pengembangan tersebut dapat dilakukan melalui pembangunan peningkatan kelas PPI Muara Angke menjadi Pelabuhan Perikanan yang sesuai dengan kebutuhan dan perkembangan kondisi terkini di lapang. Tujuan penelitian ini adalah mendeskripsikan aktivitas operasional dan mengetahui peluang peningkatan kelas PPI Muara Angke. Aktivitas operasional meliputi aktivitas tambat labuh atau pendaratan ikan, aktivitas perbekalan, aktivitas pelelangan ikan, dan aktivitas pemasaran serta distribusi. Peluang peningkatan kelas menggunakan klasifikasi pelabuhan perikanan yang meliputi aspek teknis, operasional, dan kelembagaan. Berdasarkan ketiga aspek tersebut, PPI Muara Angke telah memenuhi standar untuk ditingkatkan kelasnya menjadi Pelabuhan Perikanan Samudera.

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
