The research on the preparation and characterization of transparent electrode carbon nanosheet based gelam woods bark doped with SnO 2-SbO 2. XRD analysis showed peaks at 2θ = 26.87°; 26.38° for carbon crystal and at 2θ = 28.59°; 34.35° for SnO; at 2θ = 51.99°; 62.20° for SbO 2. SEM analysis show that the carbons have self-curling sheets that indicated defection in their surface. The carbons have self-curling sheets, which indicated that their surfaces have many defect. It assumed when exfoliation process undergone, the layers was significantly decreased as sonication process and formed rCNSO. Diffractogram XRD of CNS, CNSO and rCNSO showed diffraction peak at 2θ= 24.3°. Oxygen functional group in CNSO might cause an increasing of interlayers distance between hexagonal networks of carbon layer. It also affect electrical resistant or the conductivity. FTIR spectrum indicate that CNSO has seve ral absorption peaks at for-OH stretch for free water and alcohol. At 2337 cm-1 was showed a carboxylic acid peaks and C=C stretch at 1627 cm-1. There is a skeletal vibration rCNSO structure occurred at each graphene layers. The ratio of the integrated intensities (I G /I D = 0.89 for CNS, 0.85 for CNS-O, and 0.93 for rCNSO of Raman spectroscopy is significantly high. Electrical conductivity of transparent electrode ranges from 1.26 x 10-7 Scm-1-5.03 x 10-7 Scm-1. The highest conductivity value on transparent electrode contained rCNSO. This result inferred that the usage of rCNSO can increase electrical conductivity. Therefore, the higher value of electrical conductivity can be related to the value of L a. The average maximum absorption wavelength is observed at 350-530 nm which means that the transition of the electronic transition π→π* occurs in the conjugated carbons system. Electrical conductivity of transparent electrode ranges from 1.26 x 10-7 Scm-1-5.03 x 10-7 Scm-1. The highest conductivity value on transparent electrode contained rCNSO. The band gap values in the transparent electrode range from 2 eV-3 eV which means they have conductor-semiconductor characters.

Livestock waste containing untreated protein feed can affect soil, air and air pollution and be a source of toxins. Chickens and those around them will know this by free ammonia. Broiler manure waste can be used as a high nitro- gen nutrient that can be used as a fertilizer with additives needed by plants to increase soil fertility. The purpose of this study was to create and analyze nitrogen-rich fertilizers from broiler manure that affect plant growth or fertili- zer efficiency on productivity, growth efficiency of water spinach (Ipomoea reptans Poir.). As a result, poultry com- post contained water (63.38), nitrogen (N) (2.400%), P2O5 (3.914%), and K2O (1.113%), so N levels, P, K (7.447%). It was performed for 14 days with 3 different nutritional sources. The most effective treatment for growing aquatic spinach was the use of a combination of soil and fertilizer applied in specific proportions to obtain stem height (23.55 cm), leaf number (6.2 leaves) and leaf width (3.1 cm). Results were better compared to other treatments.
