Abstrak: Sistem IMTA (Integrated Multi Thropic Aquaculture) merupakan teknologi atau sistem budidaya yang dapat mengurangi dampak limbah dari suatu organisme dan menyeimbangkan kondisi lingkungan budidaya secara umum. Pada penelitian ini digunakan Rancangan Acak Lengkap dengan perbedaan padat tebar yaitu udang galah 13 ekor/m2 ikan tambakan 80 ekor/m2 (A) dan udang galah 13 ekor/m2 ikan tambakan 40 ekor/m2 (B). Perlakuan yang digunakan diulang tiga kali dengan masa pemeliharaan selama 60 hari. Perlakuan terbaik didapatkan pada perlakuan B ditandai dengan udang galah mendapatkan SR (85,33±1,88%), laju pertumbuhan harian (1,31±0,02%), hasil produksi (4736,03±248,20 gram), pada ikan tambakan didapatkan SR (79,23±6,05%), laju pertumbuhan harian (1,76±0,02%), hasil produksi (22166,96±1558,55 gram), serta dengan kualitas air yaitu DO (3,73-5,73) mg/L, pH (6,67-9,90), suhu (26,33-30,67) ºC, nitrit (0,04-0,11) mg/L dan amonia (0,017-0,235) mg/L.

Abstrak: IMTA (Integrated Multi Thropic Aquaculture) is a aquaculture system that integrates several organisms and focuses on the trophic level differences of each organism. IMTA will be able to improve the quality of the water and of course have a direct impact on survival rate, stocking density and increase the growth rate. The research was using completely randomized design at many treatments in the form of initial stocking density difference between freshwater giant prawns and tambakan that UG20TM50 20 prawns/m2 and 50 tambakan/m2, UG20TM100 20 prawns/ m2 and 100 tambakan/ m2. Each treatment was repeated three times. The best treatment Based on 60 days cultivation was UG20TM50 with the survival rate of freshwater giant prawn (75.83±6.29%), spesific growth rate (3.02±0.16%), total production (3065.44±79.95g) and survival rate of tambakan (80±1.32%) spesific growth rate (2.94±0.25%) and total production (10723.47±975.21g), and supported by a temperature (28.90–31.67°C), pH (6.50– 7.87), DO (4.08–5.7 mg/L), ammonia (0.00010–0.0413) mg/L.

Abstrak: Flavonoid is the most abundant naturaly-occuring polyphenolic compound which has C6-C3-C6 carbon skeleton. Flavone is a group of flavonoid with wide bioactivity spectrum. It is widely distributed in higher plants. Its bioactivities include antioxidant, HIV-1 proteinase inhibitor, strong and selective apoptotic inducer in human colon cell, and ligand for BDZ-R receptor. One of the important and widely applicable flavones synthesis route is through 1-(2-hydroxyphenyl)-3- phenylpropane-1,3-dione (1,3-diketone) acid-catalyzed oxidative cyclization. In this study, 1,3-diketone has been successfully synthesized via four-step route. In the first step, phenol was acetylated with 74–95% yields. Subsequently, phenyl acetate was converted to o-hydroxyacetophenone (o-HAP) with 34% yield via AlCl3-catalyzed Fries rearrangement. Benzoylation of o-HAP followed by Baker- Venkataraman rearrangement of the ester product using KOH in pyridine finally produced 1,3-diketone. The third and fourth steps yield were 27–44% and 82– 85%, respectively. All products in this study have been characterized spectroscopically. Melting point characterization were also conducted to the solid products.
