Abstract

The aim of this experiment was to find the effect of supplementation of zeolit and was to find the optimum level of zeolit in rations on quail performance. This experiment used 80 female Coturnix coturnix japonica of five weeks old with average body weight 145,44 ± 6,72 g (cv 4,62%). The data were analysed using Completely Randomized Design and polinomial ortogonal test. The treatments was divided to four supplementation zeolit rations treatment (0%,2%,4%,6%). Each treatment had five replication and each replication used four quails. Results of this study indicated that supplementation of zeolit (0 - 6%) in rations gave not significantly different (P ≥ 0,05) to feed consumption but gave significantly different (P < 0,05) to hen day egg production (Ŷ = 46,48 + 4,86X – 1,09 X2 ; 0≤ X ≤6 ; R2 = 0,90) and significnatly different (P < 0,05) to feed convertion (Ŷ= 4,85-0,44 + 0,10X 2 ; 0≤X≤6;R2 = 0,97). Level supplementation zeolit 2,22% was optimum to hen day egg production (51,86%) and level supplementation zeolit 2,09% was optimum to feed convertion (4,39).

Abstract

This research studied the effect of chemical activation processes of natural zeolite to heavy metal removing efficiency (%) and chemical composition of natural zeolite. The solutions 0,5M of HCl,NH4OH, KOH and NaOH was used as an activator. Heavy metal solutions (Cu, Cd, Pb, Zn, Fe and Mn) of 50 ppm was used as sample. Chemical composition of zeolite was viewed semi-quantitatively using a SEM EDX. The result indicate that Si/Al ratio was decreased because alkali activity and increased because the acid activity. The efficiency of zeolite without chemical activation on disposal heavy metals in water reached above 80% for Cd,Pb,Cu and Fe, 44% for Zn and 21% for Mn. Activation of natural zeolite with acid generally reduce the efficiency, except Fe and Pb, whereas activation with mineral salts and alkaline generally increase disposal heavy metal efficiency.

Abstract

Hydroponic is a method to growing up plant on non soil plant growth media (PGM) such as water, sand, gravel, carbon etc which mixes with other materials needed to grow the plants. The weaknesses of PGM are the low buffering capacity on electrical conductivity which can disturb the absorbtion of nutrients by plants. This can be caused by the low cation exchange capacity rate on the holding capacity of the media on nutrients. PGM such as zeoponic is made from zeolite and other materials like compost, peat moss, vermiculite, fertilizer, etc. The superiority of zeolite namely high cation exchange capacity and fertilizing efficiency rate, suitable for seed germination media and horticulture plant growth media, stable and more attractive performance. With these superiority, zeoponic became an alternative PGM which potential to increase horticulture plant production and to accommodate germination, both plantation and forestry. More over zeoponic made hydroponic became much easier to be done.

Abstract

The objective of this research was to study the growth and efficiency of broiler productivity. The research was conducted through the application of zeolite spreading treatment into the broiler housing in Non-ruminant Research Station of Animal Science Laboratory of Papua State University. Study was arranged by Randomized Sample Design with four treatments: P0 (control; without zeolite spreading); P1 (once time spreading during the research period); P3 (three times application of spreading during the research period); and P5 (five times of spreading or once a week during the research period). The application of zeolite spreading was not significantly influenced the rate growth of broiler, though there is a tendency increasing weight gain along with the increased in zeolite spreading level on the litter base. P3 (three times of zeolite spreading during research) produce the feed efficiency of 0.53. Economically, Income Over Feed Chick and Zeolite Cost (IOFCZC) per head per housing unit with the application of zeolite spreading more demand compared to housing units without spreading treatment.

Abstract

Fresh or clean water is a primary need in housing life. Clean water is used in all housing activities starting from daily needs, they are food and drink; healthy needs for example taking a bath, washing and so on, it is included non primary needs for instance watering plant, washing motorcycle or car and etc. By Increasing population growth, housing need is higher so that many simple housing like Rumah Sangat Sederhana, RSS are established in suburb. Sometimes the location of housing is landfill of swam or field area. In Fulfilment of clean water, developer usually establish shallow well. For example Gelora Persada Housing, Rajabasa, Bandar Lampung. The quality of shallow well in farmer swam or field usually have high organic content that produce bad taste and smell, high turbidity, acid (low pH), and contain high iron (Fe) element. In research was conducted in shallow well of Gelora Persada Housing, Rajabasa, Bandar lampung by using rapid sand filter wich is completed by active carbon and zeolite as adsorbance so that gained to decrease turbidity level from 23,9 NTU become 6,51 NTU; can increase pH value from 6,24 to 6,44 and it also can decrease iron (Fe) content from 3,04 mg/lt become 0,74 mg/lt.
