Abstract

The purpose of this research is to determine the composition of rice bran and corn flour which are best to planting media of while oyster mushroom and was determined of rice bran and corn flour will increase growth productivity of white oyster mushrooms. The research was conducted experimentally using Randomized Block Design (RBD) has two factors, the first factor is an addition of rice bran with treatments such as A1 = 5 kg, A2 = 1 kg, A3 = 2 kg and the second factor is an addition of corn flour with treatments such as B1 = 0.04 kg, B2 = 0.08 kg, B3 = 0.12 kg. Data analysis used Analysis of Variety (ANOVA). The results showed the highest average number of fruit bodies was 7.4 (A3B2), moreover the highest average fruit weight was 56.36 g (A3B1). However, the concluded were determined of rice bran and corn flour to planting media can increase the productivity of the growth of white oyster mushrooms with treatments A3B1, A3B2, and A3B3 can produce white oyster mushrooms up to 56.36 g. It can be concluded based the results of statistical analysis that the addition of rice bran and corn flour cannot influence the increase growth productivity of white oyster mushrooms of rice bran and corn flour will increase growth productivity of white oyster mushrooms Keywords: White oyster mushrooms, rice bran, corn flour

Abstract

Research aimed determine the total energy received by the hybrid solar tunnel dryer, and to determine the efficiency of the hybrid solar tunnel dryer. The research method was an experiment method. Date retrieve procedures include: intensity of solar radiation, the room temperature of drying, furnaces temperature and ambient temperature. The research result shows that the total heating energy of material is 45.73 kJ, evaporation energy of material is 694.40 kJ, and the air heating energy is 25.21 kJ. The thermal efficiency of hybrid dryer is 14.09%, furnace efficiency is 18.78% and total efficiency is 15.82%. Keywords: hybrid solar tunnel dryer, efficiency, total energy.

Abstract

Tujuan penelitian ini adalah untuk menganalisa pertumbuhan tanaman rumput teki (Cyperus rotundus) pada tanah terkontaminasi hidrokarbon dengan  perlakuan variasi atas tanah uji terdiri dari : 1. Kontrol tanpa limbah hidrokarbon (TP-1), 2.Penambahan limbah hidrokarbon 0.5 % (TP-2), 3. Penambahan  limbah hidrokarbon 1 % (TP-3), 4. Penambahan limbah hidrokarbon 2 % (TP-4), 5. Penambahan limbah hidrokarbon 3 % (TP-5), Penambahan limbah hidrokarbon 4 % (TP-6) dan penambahan limbah hidrokarbon 5 % (TP-7). Masing-masing tanah uji diberi perlakuan sama saat start up, yaitu dengan pemberian 0.5 gram pupuk NPK.Hasil analisis pertumbuhan tinggi tanaman rumput teki berdasarkan uji Wilayah Berganda Duncan (DMRT) pada taraf wilayah nyata student 5 % dapat disimpulkan bahwa rumput teki dapat tumbuh pada tanah terkontaminasi hidrokarbon dengan nilai TPH 0.5 %, 1 % dan 2 %, hal ini menunjukkan bahwa rumput teki dapat mendegradasi tanah yang terkontaminasi hidrokarbon.

Abstract

Tujuan penelitian ini adalah untuk mengetahui kelimpahan bakteri petrofilik dan Total Petroleum Hydrocarbon (TPH) pada sampel tanah yang diolah secara fitoremediasi dengan perlakuan kandungan konsentrasi hidrokarbon (oli bekas) atau TPH dalam contoh tanah yaitu 0.5 %, 1 %, 2 %, 3 % ,4 % dan 5 % termasuk contoh yang digunakan sebagai kontrol (0 %). Masing-masing tanah uji diberi perlakuan sama saat start up, yaitu dengan pemberian 0.5 gram pupuk NPK. Hasil analisis TPC pada masing-masing perlakuan diketahui bahwa semua contoh tanah mempunyai kelimpahan bakteri petrofilik. Sementara, hasil analisis pengamatan TPH berbanding lurus dengan aktifitas TPC yang membentuk pola seperti lintasan parabola, pola lintasan tersebut terkait dengan ketersediaan nutrisi dan kadar hidrokarbon dalam tanah sehingga nilai TPC dapat diketahui dari pengukuran nilai TPH tanah yang terkontaminasi hidrokarbon tersebut.

Abstract

The research aims to determine the effect of the aeration system for floating net cages sourced from solar energy on water quality and fish prductivity in the Talaga Batu Arang reservoir. The method used factorial randomized block design with the first factor being the location of the cage to the venturi pump and the second being the diameter of the venturi pump. The results showed that the plots afected by the venturi pump were higher at 160,05% compared to those using the venturi pump which was 134.16%. While those not given aeration at 118,61%.
