Abstract

This research was motivated by variety of understandings of political activities in villages. The article argues that village is considered as the basic for the formation of political society and government in Indonesia, which is also the basis for this democratic nation. This consideration can be seen from the activities of village’s headman elections. Headman election is a political activity that shows how democratic process can take place in village level. Therefore, headman elections cannot be separated from the dynamic development of the political situation in the village. It is not merely a power struggle within the leadership’s succession in the village or the campaign strategy applied to gain support from the wider community, but more than that it is all about prestige, dignity and honor. So for the villagers, the headman election is more emotional and rational in comparison with other elections such as local elections, even presidential elections. This research examines the Headman Election with direct analysis of three villages with different typologies. They villages are Nunggi Village in Wera, Bima (Traditional Village); Riamau Village in Wawo, Bima (Transitional Village); Rada Village in Bolo, Bima (Modern Village). Those three villages are located in the province of West Java. The result shows that practice of democracy in those three villages has worked partly according to some ideal criteria of democracy, nevertheless has not worked yet in some others criteria

Abstract

This research’s aim is to find out the effect of pyrolisis temperature to the biochar product from chocolate’s rind. The sample of rind of 20 kg is come from Indrapuri, Great Aceh. The water level of the sample is determined and then it was pyrolised with pyrolisator at the temperatures of 300, 400, and 500oC. The biochar gotten is then measured its rendemen and characterized which comprised of flying substance level, ash, bonded carbon, nitrogen, phosphor, potassium, and then the chemical substances were identified by using Gas Chromatography-Mass Spectroscopy (GCMS). Pyrolisis product of biochars at the temperatures of 300, 400, and 500oC were gained rendemen of 8.98; 8.45, and 8.35% (w/w) in a row. These biochars have physical appearance of black with brittle texture. It were gained biochars’s characteristic product of water level at 3.93% (300oC), 2.43% (400oC), and 1.50% (500oC) respectively; flying substance level at 47.13% (300oC), 29.58% (400oC) and 25.48% (500oC); ash level at15.70% (300oC), 17.14% (400oC), and 18.02% (500oC), bonded carbon at 37.16% (300oC), 53.37% (400oC), and 56.32% (500oC). The highest level of nitrogen (3.51%) is gained with biochar’s pyrolisis product at the temperature 300oC, meanwhile for the 500 dan 400oC, their nitrogen level are 1.29 and 0.86%. Phosphor level at biochar’s pyrolisis product at the temperature of 300, 400 and 500oC in a row are 0.90; 0.43; 1.39% and potassium level at this biochar are 3.34,4.73, and 4.41% consecutively. GCMS analysis result to the biochar’s pyrolisis product at the temperature of 300oC was identified 40 compounds with their main contents is 4-beta-5-dihydroneronin (22.02%), whereas at the temperatures of 400 dan 500oC respective are identified of 11 and 23 compounds, however their main contents is oleat acid with the level of 62.47 dan 49.84% in a row. It can be concluded that biochar’s characteristics of chocolate’s rind is determined by pyrolisis temperature.

Abstract

Chitosan as a material of biological origin has recently been used for recovery of metal ions. This research aims to synthesize kitosan resin resulted by the reaction of kitosan with etilendamin. In the present work chitosan was cross-linked with glutardialdehyde and subsequently treated with epichlorohydrine and ethylene diamine. The resins CR-amine was found to contain 22.7% water content,  and were insoluble in organic solvents as well as in mineral and organic acids. The concentration values of the active sites on the resins are reported. The higher concentration of active sites of CR-amine 6.01 mmol/g indicates that the “en” moieties are covalently bonded to the cross-linked resin. Several chemical modification methods were tried in increasing the uptake capacity of cross-linked chitosan bead. Among them, aminated chitosan beads formed through the chemical reaction using ethylenediamine showed the highest uptake capacity for gold ions. Uptake capacity of aminated chitosan beads was increased to about 0.8 mmol Au3+ g-1 dry mass compared to that before modification. The increase of amine groups was confirmed by IR spectrum and measurement of amine concentration and surface condition on aminated chitosan bead was also confirmed by  SEM.

Abstract

Researcher has conducted a study on the stability of natural pigments which is derived from sweet potato (Ipomea batatas). The aim of this study was to determine the stability of natural pigments from sweet potato of the variation of heating temperature, long warm-up, long storage and long exposure to sunlight. The populations of this study those fresh sweet potatoes ibaraki varieties as much as 2 kg. The samples used in this study were 100 grams of sweet potatos that have been peeled and grated, then be extracted with 20 mL of distilled water at a temperature of 50 0C and blended so that it became a slurry and then squeezed, then do the identification of anthocyanin compounds in the sample. The extract of sweet potato at pH 6 measured the wavelength of maximum, then anthocyanin concentration was calculated using the pH-differential method. Further, it was tested the stability of the dye to the variation of heating temperature, long warm-up, long storage and long exposure to sunlight at a wavelength of maximum. The results showed that at pH 6 sweet potatos have a wavelength of 536 nm and concentraining anthocyanin with 10,02 mgL-1 of concentrations. Stability of the dye from sweet potatos extracts to heating temperature variation decreased absorbance values by an average of 0,004, a decreased of the heating value of the average absorbance of 0,008 and of storage duration decreased the absorbance values by an average of 0,007. Whereas long exposure to sunlight absorbance values increased by an average of 0,009. The conclution of the researche is the intensity of sweet potatoes extract color was reduced to the variation of heating temperature, heating time and saving time. The intensity of yam’s extract color increased to along exposure of sunlight.

Abstract

In this research, a series of batch laboratory experiments were conducted to examine the feasibility of Meandg’s (Litsea sp) saw dust for the removal of cadmium from simulated aqueous solution by using adsorption method. The research was carried out by studying the influence of pH of initial solution, contact time, adsorbent dosage, stirring speed, and the initial concentration of cadmium. The sawdust particle size used was < 150 mesh and the experiments were conducted at room temperature of 27oC (±2oC). The residual concentration of cadmium from all batch experiments were analyzed using Atomic Adsorption Spectrophotometer (AAS) and each component equilibrium data was analyzed using Langmuir and Freundlich adsorption isotherms. The research findings shown that the optimum conditions are found to be at the pH of 6, the initial concentration of cadmium of 500 ppm with contact time of one hour, 3 gram of sawdust, and the optimum stirring at the speed of 350 rpm. The adsorption capacity of medang sawdust according to Langmuir and Freundlich isotherms are found respectively to be of 2.29 mg/g and 0.55 mg/g.
