Judul: Analisis Hukum dan Kelembagaan Penegakan Hukum di Bidang Perikanan
Abstrak: Permasalahan illegal fishing mengakibatkan sektor kelautan dan perikanan Indonesia tidak mampu dimanfaatkan secara optimal. Kerugian dapat dilihat dari beberapa aspek, diantaranya aspek ekonomi yakni kerugian secara finansial, aspek sosial berupa penyebaran penyakit berbahaya dan aspek ekologis seperti over fishing dan destructive fishing. Lembaga penegak hukum yang berwenang yang menjadi objek peneltian adalah Polisi Perairan, TNI AL, dan PSDKP. Tujuan dari penelitian ini adalah untuk mengetahui tugas pokok dan fungsi kelembagaan penegakan hukum di bidang perikanan, menganalisis tumpang tindih kewenangan antar lembaga penegak hukum di bidang perikanan berdasarkan landasan hukumnya, dan memberikan rekomendasi efektifitas penegakan hukum. Penelitian ini menggunakan analisis kelembagaan, analisis hukum dan analisis SWOT. Penelitian menghasilkan bahwa bahwa tiga lembaga penegakan hukum yaitu Polair, TNI AL dan PSDKP menjalankan fungsi penegakan hukum sesuai dengan dasar hukum tersendiri. Variabel kewenangan Polair diamanahkan dengan 4 dasar hukum, TNI dengan 5 dasar hukum, dan PSDKP dengan 3 dasar hukum. Variabel kewilayahan menjabarkan bahwa ketiga lembaga memiliki wewenang berbeda pada wilayah perairan pedalaman, perairan kepulauan, laut teritorial, dan ZEEI. Prioritas strategi penegakan hukum dengan dua urutan terbesar dari penelitian adalah peningkatan kerjasama regional dan internasional dalam menghapuskan illegal fishing dan destruktive fishing dan menambah jumlah kapal patroli dan penambahan teknologi canggih.

Judul: Analisis sistem bagihasil berdasarkan perspektif hukum adat dan undang-undang bagi hasil perikanan di PPN Pekalongan
Abstrak: Pekalongan merupakan basis perikanan tangkap terbesar di Indonesia yang mempunyai pelabuhan perikanan dan pangkalan pendaratan yang berstatus Pelabuhan Nusantara, sehingga banyak masyarakat Pekalongan yang melakukan usaha penangkapan ikan. Usaha penangkapan yang dllakukan nelayan Pekalongan menyebabkan terjadinya posisi tawar antara nelayan penggarap dan nelayan pemilik serta proporsi bagi hasil. Pada umumnya bagi hasil yang digunakan nelayan Pekalongan adalah sistem bagi hasil berdasarkan hukum adat. Tujuan penelitian ini adalah untuk mengetahui sistem bagi hasil perikanan laut yang digunakan oleh nelayan Pekalongan, dan mengetahui tingkat kesejahteraannya serta mengetahui faktor-faktor penghambat pelaksaanaan UUBHP.

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
