Judul: Dayasaing Usahatani Melon Apollo di Kota Cilegon.
Abstrak: Melon Apollo merupakan salah satu varietas melon unggul. Kota Cilegon sengaja dipilih menjadi lokasi penelitian karena merupakan penghasil melon Apollo terbesar di Provinsi Banten. Tujuan penelitian ini yaitu : (1) menganalisis dayasaing usahatani melon Apollo di Kota Cilegon, (2) menganalisis pengaruh kebijakan pemerintah dan pengaruh perubahan faktor eksternal terhadap keuntungan dan dayasaing usahatani melon Apollo. Penelitian ini dianalisis menggunakan metode Matriks Analisis Kebijakan (PAM) dan analisis sensitivitas. Hasil analisis menunjukan bahwa usahatani melon Apollo di Kota Cilegon memiliki dayasaing karena memiliki nilai PCR < 1 (0.526) dan DRCR < 1 (0.572). Secara keseluruhan, kebijakan input-output yang diterapkan oleh pemerintah sudah efektif dalam meningkatkan dayasaing. Analisis sensitivitas menunjukan bahwa produktivitas output sensitif mempengaruhi dayasaing, sedangkan harga output, harga input, dan kurs rupiah tidak sensitif dalam mempengaruhi dayasaing melon Apollo.

Judul: Analisis Usahatani Melon Apollo Berdasarkan Standar Operasional Prosedur (SOP) dan Non SOP di Kota Cilegon
Abstrak: Standard operating procedures (SOP) of cultivation melon apollo varieties constituting a form of rules in the activities of cultivation that the goal is to increase the productivity, based on uniformity fruit characteristics, and increase the income of farmers and the regions particularly in Cilegon. The objective of the study is to compare SOP application, to analyze input that affects the cost structure of farming which apply SOP and non SOP, and to analyze the income of melon farmer. The result showed productivity, income of both SOP and non SOP were siginificantly different at α 10 percent, but the value of R/C ratio between the SOP and non SOP having value not different. So that SOP of benefits against the productivity and income of farmers, so the SOP of the farming business to continue.

Judul: Removal of Hexavalent Chromium with Scrap Iron Filling.
Abstrak: Chromium is a transition element commonly found in the environment as trivalent and hexavalent forms. Apparently, the hexavalent form is much more toxic than the trivalent form. Textile wastewater treatment is required in order to prevent hexavalent chromium to contaminate the environment. The methods of this research consisted of effect of pH determination, effect of agitating rate determination, effect of agitating time determination, and effect of iron level determination; and its application in textile wastewater sample. The methods used in textile wastewater application are: determination of textile wastewater hexavalent chromium concentration, determination of textile wastewater hexavalent chromium concentration with standard addition method, and removal of hexavalent chromium in textile wastewater with scrap iron filling. Concentration of hexavalent chromium was determined using visible light spectrophotometry method. Optimum conditions of pH, agitating rate, iron amount, and agitating time obtained were pH 3, 450 rpm, 5 grams, and 10 minutes giving concentrations of hexavalent chromium 16.98 ppm, 15.96 ppm, 0.24 ppm, and 0.14 ppm, respectively. Iron filling could effectively remove hexavalent chromium ions from textile wastewater in a relatively short time. Absorbance of hexavalent chromium in textile coloring process wastewater after the addition of iron filling was 0.002, whereas in textile final wastewater was 0.000.
