Background: Residents of the Pacar Village, Rembang Subdistrict community generally have dug wells, these wells are used for daily needs such as washing, bathing, cooking and others. In addition, the disposal of domestic household waste is generally through sewers which lead directly to the sea. That is because the condition of the house is a few meters from the sea. Dug wells that are close to sea water, the routine habits of poor domestic waste disposal, have the potential to contaminate dug well water. If this happens then the water condition is not suitable for consumption. Therefore we need a study to find out the quality of ground water (dug wells) in the area.Methods: This type of quantitative research uses random random sampling with research samples of 30 dug wells, data analysis is performed using Spearman's correlation test.Results: There is a correlation between the distance of dug wells to the shoreline against TDS (p< 0,000, r = + 0,717), salinity of dug well water (p<0,000, r = + 0,711) and there is no correlation between distance and temperature (P=0,475, r = -0,137).Conclusions: There is an influence between the distance of dug wells on the value of Total Dissolved Solids (TDS), Salinity and there is no influence between the distance to the temperature. Dug well water in Pacar Village, Rembang District, Rembang Regency.

This research aims to study the production of essential oil from Piper Cubeba using the solvent-free microwave extraction (SFME) method. Before extraction, the raw materials are prepared in the form of grains and powders to vary the size of the raw materials. Time variation was carried out at microwave power 180 Watt Analyses were then performed on the resulting essential oil using both physical and chemical tests of density and solubility with 96% alcohol. Analyses of chemical compounds within the essential oil were then performed using the Gas Chromatograph Mass Spectrometry (GC-MS). It was found that the production of essential oil from Piper Cubeba using the SFME method was affected by microwave power, grain size, and treatment duration. Results from physical and chemical analyses revealed that the resulting cubeb oil has 0.86 g/mL density, which means that essential oil produced using the SFME method is lighter compared than those produced using MAHD methods. Results from GC-MS analyses showed eight components detected from the production of essential oil from Piper cubeba using the SFMEmethod; Copaene (39.28%), Cubebene (23.83%), Isoledene (11.66%), Naphthalene (6.65%), Phellandrene (5.81%), Asarone (5.71%), Cadidene (4.90%), and Caryophyllene (2.16%) which contents belong to the sesquiterpene group

The Covid-19 virus in 2020 had a tremendous impact on almost all fields, one of which was in the field of education. Online learning is a solution for teaching and learning activities during the Covid-19 pandemic. This study aims to determine the effect of online learning on interest in learning in chemistry courses during the Covid-19 pandemic. Respondents taken were students of the Faculty of Industrial Technology, University of Nahdlatul Ulama Al Ghazali, Cilacap. The research design used linear regression analysis, with the data collection method in the form of a questionnaire. The results of the analysis for the normality test show a sig value of 0.200 more than 0.05 which means the data is normally distributed and the results of the linearity test show a sig value of 0.393 more than 0.05 which means that the correlation between online learning variables and interest in learning is linear. Based on the results of the linear regression test, the regression coefficient of 0.779 is positive, so it can be said that the direction of the influence of the variable x on y is positive. Based on the significance value: the table coefficients obtained a significance value of 0.001 <0.05, so it can be concluded that the online learning variable (x) has an effect on the learning interest variable (y). Based on the t-count value of 3.607> t-table 2.0484, it can be concluded that the online learning variable (x) affects the learning interest variable (y)

Cooking oil is one of the primary commodities people need to process food. Repeated use of cooking oil at high-temperature heating produces foul smell that reduces the quality and nutritional value of fried food. Decomposition consists of negative affects quality, but it also results in unfavorable flavor and reduced nutritional value of fried food. An alternative method to treat used cooking oil is adsorption with carbon made of coconut shells. This research aims to lower the levels of acid and peroxide numbers of used cooking oil by purifying it with activated carbon. The acid number determined using the acidimetric and alkalimetric titration method, while the peroxide number measured using the iodometric titration method. These two methods used to analyze samples of fresh cooking oil, used cooking oil, and used cooking oil treated with activated carbon. Results showed a decrease in acid number 34.1449% the second, 29.4103% the fourth use, and 37.5092% on the sixth use of cooking oil. Meanwhile, acidity reduced by 34.1508% the second use, 29.3883% the fourth use, and 37.5066% the sixth use of cooking oil. It found that peroxide number experienced a decrease in 81.2836% the second use, 85.3674% the fourth use, and 62.2462% the sixth use of purified cooking oil.

Semiotic is study of sign. The signs deliver communicative message through verbal (gestures and utterance) or non-verbal information (body language) that leads viewers comprehend the message well. Based on the type, sign divided into three, they are icon, index and symbol. This research analyzes three types of sign, icon, index, symbol on cigarette advertisement. The data of this research are cigarette advertisements which consist of 2 different cigarette brands from two biggest cigarette companies in Indonesia Djarum and Gudang Garam. Those data are then classified into sign (icon, symbol and index). This research applied descriptive qualitative method. To classify the type of sign, the researcher used Pierce theory (Coleman, 2017). Based on the analysis on cigarettes advertisement, each advertisement contains own icon, index, symbol meaning. The icons in the cigarettes advertisement consisted of pictures of human, things and cigarettes productâ€™s logos. While the indexes found in television cigarettes advertisement were mostly the pictures of the human attitude, things, and slogan or the cigarettes brands. From the icon, index, symbol, it can be seen the male characters as their theme. The men's characters used as the theme of cigarettes advertisement are brave, tough, masculine, fond of challenges and strong.

ndonesian turpentine contains 65-85% α-pinene, 1% camphene, 1-3% β-pinene, 10-18% 3-carene and 1-3% limonene. The largest content of turpentine is alpha pinene. Alpha pinene is also a monoterpene compound that has double bonds and is the main raw material in the perfume industry. In addition, alpha pinene is also an important raw material for the manufacture of fine chemicals that have high sales value such as pine oil, camphor and alpha terpineol. To increase the sale value, alpha pinene can be further processed into derivative compounds such as alpha terpineol and alpha terpinyl acetate. Both are valuable derivative compounds used in the perfume industry and the pharmaceutical industry. Hydration is the reaction between alpha pinene and water to produce alpha terpineol compounds. In the reaction process that will be carried out on alpha pinene usually uses a catalyst that can accelerate the reaction rate without becoming a byproduct, catalyst used in this study is a type of resin. This study aims to study the effect of temperature variables at temperatures of 65, 75, 85 and 950C. The conversion of alpha pinene increases with increasing reaction temperature. Assuming a reversible reaction, the relationship of temperature to each reaction rate constant is determined according to the Arrhenius equation.
