Liquid organic fertilizer is a solution from the fermentation of organic materials by involving microorganisms as a destructor of macromolecular compounds into minerals that are easily absorbed by plants. The quality of organic fertilizers is the main ingredient to get productive plants. The quality of organic fertilizer is determined by the concentration of macro nutrients such as nitrogen (N), potassium (K), and phosphorus. Getting high amounts of macronutrients fertilized organically is not easy. Macro-nutrients in organic waste with high concentrations are very difficult to obtain because each organic waste does not have all three macro-nutrients simultaneously. It takes a combination of organic waste to increase the concentration of macro nutrients in organic fertilizers. The combination of tofu whey with banana waste is one technique to obtain organic fertilizers that are high in phosphorus content. This study aims to obtain the effect and conditions of fermentation on the addition of mass of banana waste to produce optimum levels of phosphorus (P) in liquid fertilizer of tofu waste. The type of research used is pre-experimental research. The design of this study used a completely randomized design (CRD) with two factors, namely the first factor was the mass of banana waste (X) (X1 = 250 grams, X2 = 500 grams, X3 = 750 grams) and the second factor was the fermentation time (Y) (Y1 = 14 days, Y2 = 28 days, Y3 = 42 days). Determination of phosphorus content using UV-Vis spectroscopy instrument. Parameters measured were phosphorus (P) levels in liquid organic fertilizer. The independent variables in this study were the mass of banana waste and fermentation time, while the dependent variable in this study was the phosphorus content of the liquid fertilizer produced. The results of the analysis show that the phosphorus content (P) produced is X1Y1 = 0.1%, X2Y1 = 0.5%, X3Y1 = 0.09%, X1Y2 = 0.5%, X2Y2 = 2%, X3Y2 = 1.9 %, X1Y3 = 0.2%, X2Y3 = 0.5% and X3Y3 = 0.5%. There is an effect with the addition of a mass of banana waste as much as 250 grams at a 12-day fermentation time. It can be concluded that the liquid fertilizer produced has exceeded the SNI quality standard.

The results of observations and interviews on lecturers and students show that students tend to pay less attention when the lecturer explains the material. The interaction is also still impressed one way, only lecturers to students. It shows that students' interest toward organic chemistry learning is still low and considered difficult by them. Students are less directed in constructing their knowledge, resulting in many misconceptions and low student's thinking ability. This happens because the union has not multi-level chemical representation that includes the macroscopic, microscopic and symbolic levels in the learning process undertaken. This research was conducted on chemical education students at IKIP Mataram who took organic chemistry course II. This research was conducted from September to December 2016 consisting of preliminary research, product trial, data processing and preparation of research result report. This study aims to determine the feasibility and effectiveness of teaching materials with inquiry assisted approach Computational Chemistry program in improving students' creative thinking ability.

Copper is one of the toxic metals for health and the environment. In humans, high doses of copper metal can cause vomiting, dizziness, weakness, kidney and liver symptoms, anemia, to coma, and in severe cases, the patient can die. Judging from the dangers, proper waste management is needed to reduce the side effects of these pollutants. A practical and inexpensive technology is an adsorption adsorption technique using an efficient and easily available natural adsorbent, namely tofu dregs. The protein contained in tofu is one of the reasons for using tofu waste as an adsorbent. The absorption of amino acids that form two-charged ions (zwitter ions) is owned by proteins. Toxic metal can be bound to protein as metallotionein. The study consisted of four stages, namely (1) Analysis of initial copper content in silver craft waste; (2) Preparation of tofu waste adsorbent; (3) Characterization of tofu dregs adsorbent; and (4) variation of adsorption contact time. The study used a laboratory-scale experimental method. The adsorbent was contacted with the sample using a magnetic stirrer at various times. Instrument Atomic Absorption Spectrometer was used for the analysis of copper metal content and identification of its functional groups using an infrared spectrometer with the result that tofu waste has functional groups -OH, NH (stretching), CH (aliphatic), C=O, -OH (bending vibrations). , and CO. Copper metal content obtained is 19.5979 ppm. The optimum adsorption time was reached at 120 minutes with an optimum adsorption efficiency of 54.88%.
