Abstract

This study aims to determine differences in nutrient levels in the manufacture of compost from rice straw waste with Trichoderma sp. activator. to the value of the C/N ratio and the nutrients N, P, K. The superiority of Trichoderma sp. Among others, it is easy to apply, does not produce toxins, is environmentally friendly, does not disturb organisms in the soil and does not leave residues in plants or soil. In making compost in compost tanks, the use of Trichoderma sp with a combination of ash and lime (JKAL) can increase the content of C-Organic, N-Total, Phosphorus and Potassium with respective values ??of 20.34%, 0.90%, 0 , 40% and 0.40%. The lowest C/N content was shown in the use of Trichoderma sp added with Ash (JAL) which was 22.0. In the treatment of making compost in containers, the use of Trichoderma sp with a combination of ash and lime (JKAD) was able to increase the content of C-Organic, N-Total and Phosphorus and was able to reduce the value of C/N with an average value of 19.8% respectively , 21.67%, 0.18% and 21.67%. The highest average value of Potassium (K) content shown in the JAD treatment was 0.46%.

Abstract

Higher education has a noble task, namely disseminating science and technology and cultural arts to all citizens with personal and institutional references to the principles of scientific methodology. Community capabilities need to be developed from various social strata by conveying the Tri Dharma of Higher Education, which is the main task of lecturers, this is a form of effort from universities to accelerate competitiveness to encourage the realization of government programs in national development. This community service activity is in collaboration with partners, namely high school and vocational schools (SMA / K) in Samarinda. The target of this program is to introduce and disseminate laboratory-based processing of plantation commodities at the Samarinda State Agricultural Polytechnic (PPNS) campus. From the results of observations in the field, there are still many high school / vocational students in Samarinda who are still not familiar with the processing technology of plantation commodities and the processing process and analysis techniques. The method of this activity is the delivery of material directly (lectures), discussion and deepening of the material by means of questions and answers, as well as simulation of laboratory-scale plantation commodity processing technology. The result of the implementation of this service is an increase in students' knowledge regarding plantation commodity processing technology and the students involved in this activity are able to master plantation commodity processing technology.

Abstract

Samarinda is the capital city of East Kalimantan. As the capital city on the second largest island in Indonesia, Samarinda is home to 834,824 residents. A problem that often arises in densely populated cities is fire. In Samarinda, from 2015 to 2022, there have been at least 2,349 fire incidents with a burned area of 8,090,755 m2 so this city has become one of the cities that most often experience fires on Kalimantan. Several supporting facilities and infrastructure owned by the Samarinda Fire and Rescue Agency, such as hydrants and fire posts have been expanded in number. However, most of these supporting facilities have not been integrated with a good coordinate system. So, when a fire occurs, it takes time to identify the location of these vital facilities. As an effort to solve this problem, the Geological Engineering Study Program, Faculty of Engineering, Mulawarman University and Samarinda State Polytechnic of Agriculture held community engagement activities in the form of geographic information system (GIS)-based application training for Samarinda Fire and Rescue Agency officers. This program aims to provide additional competencies needed by field officers in integrating data on facilities and infrastructure such as hydrants and fire posts into the Samarinda geoportal system. Based on the results of this activity, Samarinda Fire and Rescue Agency officers are skilled in operating applications that can integrate coordinate-based facilities and infrastructure data into a geoportal system, including measuring the burned areas accurately and precisely so that fire incidents in Samarinda can be minimized.

Abstract

Analysis of the influence of vegetation density levels on the concentration of Total Suspended Solids (TSS) in aquatic areas is crucial in the Pomalaa District, an area characterized by extensive mining activities. This research aims to examine changes in vegetation density conditions and analyze the influence of vegetation density levels on TSS concentrations in the aquatic region. Changes in vegetation density conditions are analyzed through multi-temporal remote sensing image processing using the NDVI method. The TSS concentration is analyzed using the gravimetric method. Meanwhile, the influence of vegetation density level on TSS concentration is analyzed using the Pearson correlation coefficient equation. The results of the research show that there has been an increase in the area with very low levels of vegetation density and a decrease in the area with high levels of vegetation density in the period 2014 to 2023. The calculated results of TSS concentrations at the research location are 78 mg/l to 111 mg/l. The correlation analysis shows that the broader the area with very low vegetation density, the higher the TSS concentration in the aquatic environment. Additionally, the larger the area with high vegetation density, the lower the TSS concentration value of the water at the research locations.

Abstract

As a travel destination, Saudi Arabia attracts individuals worldwide, including tourists, investors, and immigrant workers, for various purposes, including trip planning, investment decisions, and remittance transfers. Indonesia and Pakistan are the biggest countries that send Umrah and Hajj pilgrims. We need to predict currency rates in 3 pairs of currencies that are frequently used by travel agencies, Hajj and Umrah pilgrims, such as the Saudi Riyal (SAR) against the Pakistani Rupee, the SAR against the Indonesian Rupiah (IDR), and the United States Dollar (USD) against the IDR. This study utilizes Long Short-Term Memory (LSTM) models, the machine learning approach for predicting currency pairs exchange rates. Previous studies succeeded in predicting USD/IDR rates using the LSTM time series-machine learning approach, but the root mean square error (RMSE) value was the worst 271. The research aims to optimize the LSTM to predict the currency rate in the future using historical data obtained from investing.com. We use Python to predict the currency rate pairs, following an experimental investigation with adjustments to the batch size, epoch, and prediction days. The experimental results show that SAR/PKR has a smaller mean square error (MSE) of 0.94, RMSE of 0.97, and MAE of 0.61, while SAR/IDR and USD/IDR Excel with Models 2 and 1 have smaller MSEs of 317.79 and 6654.41, RMSEs of 17.82 and 81.57, and MAEs of 10.54 and 50.12, respectively.
