Judul: Hubungan antara Kondisi Sosial Ekonomi Masyarakat Nelayan dengan Kelestarian Lingkungan di Desa Jenggala
Abstrak: Kemiskinan menjadi salah satu pemicu terjadinya kerusakan terhadap lingkungan. Kerusakan lingkungan sulit dihindarkan ketika penduduk masih dililit kemiskinan. Keterdesakan secara ekonomi mengakibatkan eksploitasi besar-besaran terhadap sumberdaya alam. Tujuan dari penelitian ini adalah untuk: (1) menganalisis kondisi sosial ekonomi masyarakat nelayan di daerah pesisir yang erat hubungannya dengan pengelolaan lingkungan, (2) Menganalisis hubungan karakteristik sosial ekonomi dengan perilaku masyarakat nelayan dalam menjaga kelestarian lingkungan di daerah pesisir. Metode penelitian yang digunakan untuk menggali fakta, data, dan informasi dalam penelitian ini digunakan pendekatan kuantitatif dengan kuesioner yang didukung dengan data kualitatif dengan wawancara mendalam dan observasi. Hasil penelitian ini menunjukkan bahwa tidak terdapat hubungan antara indikator-indikator kondisi sosial ekonomi masyarakat nelayan dengan ketersediaan sarana dan prasarana sanitasi. Di sisi lain, ketersediaan sarana dan prasarana sanitasi juga tidak memiliki hubungan dengan perilaku masyarakat dalam menjaga kelestarian lingkungan.

Judul: Analisis faktor sosial ekonomi penyebab kemiskinan pada masyarakat nelayan  : (Studi kasus di Desa Eretan Wetan, Kecamatan Kandanghaur, Kabupaten Indramayu)
Abstrak: Salah satu masalah kebijaksanaan sektor pertanian dalam dasa warsa yang akan datang adalah masalah penggang- guran atau setengah pengangguran yang sangat erat hubungan- nya dengan masalah kemiskinan di Indonesia. Hasil penelitian di daerah Eretan Wetan Kecamatan Kandanghaur, Kabupaten Indramayu, Jawa Barat menunjukkan bahwa kebanyakan juragan disana adalah juragan darat dan biasanya mereka mempunyai pekerjaan lain selain sebagai nelayan, sedangkan buruh nelayan disana pada umumnya tidak mempunyai pekerjaan lain selain sebagai nelayan, sehingga selisih pendapatan nelayan dan buruh nelayan sangat tajam. Kondisi perumahan dan lingkungan nelayan di desa penelitian pada umumnya tidak memenuhi syarat kesehatan. Kondisi dan keadaan lingkungan rumah tersebut berhubungan erat dengan keadaan kesejahteraan penghuninya dan dapat dipakai sebagai indikator, untuk menentukan adanya kemiskinan pada masyarakat tersebut. ...

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
