Abstract

Abstrak. Sumber energi terbarukan (biogas) merupakan jenis sumber energi yang bersifat ramah dan tidak mencemari lingkungan. Proses pembuatan biogas berasal dari dekomposisi bahan organik secara anaerob (tanpa udara). Tujuan dilakukannya penelitian ini adalah untuk mengetahui pengaruh berbagai jenis limbah organik terhadap suhu pada pembentukan gas metan (CH4) dan karbon dioksida (CO2) pada biogas. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan empat perlakuan yaitu P1 dengan menggunakan limbah ampas tahu sebanyak 4 kg dan air 4 liter, P2 menggunakan kotoran sapi sebanyak 4 kg dan air 4 liter, P3 menggunakan limbah pasar sebanyak 4 kg dan 4 liter air dan P4 menggunakan campuran limbah ampas tahu, kotoran sapi dan limbah pasar sebanyak 4 kg dan air 4 liter. Data hasil pengamatan dianalisa menggunakan ANOVA pada taraf nyata 0,05 (5%). Apabila antar perlakuan terdapat perbedaan yang nyata maka dilakukan uji lanjut BNJ (Uji Beda Nyata Jujur) pada taraf nyata 0,05 (5%). Hasil penelitian menunjukkan bahwa Karbon dioksida (CO2) yang terukur pada pembuatan biogas tertinggi yaitu pada perlakuan bahan baku limbah ampas tahu sebesar 4801,7222 ppm dan yang terkecil pada perlakuan bahan baku kotoran sapi sebesar 2177,417 ppm. Gas metan (CH4) pada pembuatan biogas tertinggi terukur pada perlakuan dengan menggunakan bahan baku kotoran sapi yaitu sebesar 6442 mol dan yang terkecil pada perlakuan dengan bahan baku limbah ampas tahu sebesar 340,25 mol. Sehingga dapat disimpulkan bahwa kandungan biogas terbaik ditemukan pada limbah organik kotoran sapi dengan kandungan CH4 tertinggi sebesar 6442 mol.Analysis of Carbon Dioxide and Methane Gas Content in Making Biogas From Organic WasteAbstract. Organic waste with unlimited sources and high volumes can cause environmental pollution, so optimal processing is needed. Processing that is considered capable of accommodating large-scale processing and whose output has high economic value is biogas. The manufacturing process uses an anaerobic fermentation method using a technology called a digester. The research aims to see the effect of different types of organic waste on the content of carbon dioxide and methane gas. The research design used a Completely Randomized Design (CRD) consisting of four treatments with 3 replications. The treatment in question is T1 with tofu dregs waste with water, T2 with cow dung plus water, T3 with market waste plus water, and T4 with a mixture of tofu dregs, cow dung and market waste with water. The research data were analyzed using ANOVA at a significance level of 0.05 (5%) with the help of SPSS. If significant data is found, a BNJ test with a real level of 5% is carried out. The results of the research showed that the highest carbon dioxide (CO2) content in tofu waste was 4801.72 ppm and the lowest was in cow dung at 2177.42 ppm, while the formation of methane gas (CH4) was highest in cow dung waste, namely 6742.12 mol and the lowest in waste. tofu dregs amounted to 352.65 mol. So it can be concluded that the best biogas content is found in cow dung organic waste with the highest CH4 content of 6742.12 mol

Abstract

A country's development progress can be measured by good economic growth. If economic growth experiences rapid growth, it will usually trigger price increases. The occurrence of an uncontrolled increase in the price of goods or services for the needs of the community can cause inflation. inflation rate for a country is an inflation rate that has a low and stable value. One alternative is to provide an overview of the inflation in Indonesia by using forecasting analysis techniques. In this study, inflation forecasting analysis in Indonesia was carried out using the ANN Backpropagation and ARMA methods. The purpose of this research is to compare the performance results of the two methods and look at the best method for forecasting results. Based on the results of the analysis with the ANN Backpropagation method, the best network architecture model was ANN(7-4-1) using an epoch value of 400 and a learning rate of 0,1 with a value of MSE = 0,0112 and RMSE = 0,1065. While the results of the analysis using the ARMA method, the best model was obtained, namely ARMA(2,0,1) with the value MSE = 0,0648 and RMSE = 0,2545. So that the most optimal method used to predict inflation for the next period is the ANN Backpropagation method because it has a smaller error value. From this model, the results of forecasting inflation rates for the months of May to December 2022 are also obtained with a range of 0,01% to 0,5%.

Abstract

Fossil energy reserves to date are dwindling inversely proportional to the amount of consumption. So to overcome this problem, alternative energy is needed, one of which is biogas which is sourced from organic waste. The biogas production process has so far experienced many obstacles so that the formation of pressure has not been optimal. The aim of the research was to create a model to see the magnitude of the influence of humidity and temperature on the pressure of the biogas produced. The method used is multiple linear regression with the following stages, identifying variables, testing classical assumptions, model building, and model goodness. Based on the results of the analysis, the model Y ̂=17.029-0.042X_1+3.480X_2 is obtained. Simultaneous test results show that simultaneously humidity and temperature have a significant effect because the sig is 0.000<α(0.05). The results of the partial test (T-Test) of each variable also showed significant results on biogas pressure because the sig was 0.000<α(0.05). The coefficient of determination of 0.8180 means that humidity and temperature variables affect the formation of biogas pressure by 81.80% and the rest is influenced by other factors such us pH, C/NRatio, starter, and so on.

Abstract

Abstrak bahasa Inggris: Cassava tape is originally local food from Indonesia. This product is fermented resulting different sensory properties. The application of various packaging to wrap cassava when making tape; however, there is no research, which compares the effect of several packaging to organoleptic properties of cassava tape. This research aims to figure out the effect of different packaging to organoleptic characteristic of cassava tape. The result was designed using completely randomized design (RAL) and analysed by variant analysis (Anova). Duncan Multiple Range Test (DMRT )was used to test significant results. According to the analysis, there was a significant difference in different packaging used to the organoleptic perception of cassava tape, especially in flavor, taste, sweetness level, and texture. There was a strong alcoholic flavor, a very liked taste, high sweetness level, and soft texture. The use of plastic jar tends to trigger no alcoholic flavor, unliked taste, no sweetness, and hard texture. When using a plastic bag it had almost similar flavor, color and taste to the tape wrapped with banana leave; however, it has less sweetness and less soft texture. In conclusion, based on the result it is recommended to pack the cassava with banana leave to obtain greater sensory properties according to what consumers’ desire.

Abstract

This study aimed to determine the effect of attendance level, participation level, and students’ motivation on students’ achievement in the Mathematics for Senior High School course. The study employed a quantitative approach with an ex post facto research design. The population consisted of 22 students enrolled in the Mathematics for Senior High School course, and all population members were selected as the research sample using the total sampling technique. Data were collected through documentation, observation, and questionnaires. The data were analyzed using multiple linear regression analysis with the assistance of SPSS for Windows. The results showed that attendance level, participation level, and students’ motivation simultaneously had a significant effect on students’ achievement, with a significance value of 0.001 < 0.05. However, partially, attendance level, participation level, and students’ motivation did not have a significant effect on students’ achievement. The coefficient of determination (R²) was 0.579, indicating that 57.9% of the variation in students’ achievement could be explained by attendance level, participation level, and students’ motivation, while the remaining percentage was influenced by other factors outside the study. Based on the findings, it can be concluded that improving students’ achievement in the Mathematics for Senior High School course is not only influenced by attendance, participation, and motivation individually, but also by the integration of various academic and psychological factors in the learning process.

Abstract

This study aims to group earthquake damage from its magnitude scale and visualize it on a geographical map. The magnitude of the earthquake was grouped using the K-means model. It is one of the most popular and effective clustering models in grouping data, such as earthquake data. The dataset used in this study is earthquake data for the last ten years on Lombok Island. The optimal number of clusters was used which is 2 in this case, based on the highest Silhouette score of 0.930. The highest Silhouette score shows the optimal number of clusters. The cluster on the geographical map shows most earthquakes' distribution in Northen Lombok Island with cluster 1 consisting of 145 earthquakes, while cluster 2 consists of 3 earthquakes. In addition, the earthquake's damage based on its magnitude scale, there were four different kinds of earthquake damage: slight, limited, minor, and severe damage that have occurred for the last ten years in Lombok Island. Minor and Slight damages were dominant, respectively. However, severe damage occurred in the northern part of Lombok Island due to an earthquake in 2018.
