Analysis Of Environmental Sanitation at Cadika Urban Forest Park in Medan Johor Sub-District, Medan City in 2025
No full textCadika Urban Forest Park is a green open space and a popular tourist attraction for the people of Medan. The sanitation conditions in the park show that there are uncovered trash bins, organic waste burning practices, and poorly maintained toilets that cause unpleasant odors. These conditions can disrupt visitor comfort and pose health risks, necessitating a comprehensive assessment of the park’s environmental sanitation conditions. This study is descriptive in nature, employing observation and interviews with sanitation staff and park supervisors. The study includes an analysis of sanitation facilities, including clean water supply, toilets, wastewater drainage systems, waste management, and sanitation infrastructure; supporting facilities, including educational resources, health facilities, and fire extinguishing equipment; and operational resources at Cadika City Forest Park. The results of the study indicate that the overall environmental sanitation conditions do not yet meet healthy standards. Environmental conditions fall into the unhygienic category. Sanitation facilities fall into the hygienic category. Supporting facilities are categorized as unfit for health. The operational human resources aspect shows that staff are available but have not received specialized training, do not work according to technical standards, and are not supervised through a structured evaluation system. Therefore, a comprehensive improvement in facility quality, enhanced staff capacity through training, and the implementation of a structured supervision system are necessary to optimally improve the environmental sanitation quality of the park.151 pagesSkripsi Sarjan
The Influence of Adding Andaliman (Zanthoxylum acanthopodium) on the Microbiological and Organoleptic Quality of Patty from Culling Layer Chicken Meat
No full textOne of the efforts that can be made in utilizing culling chickens as food products is by processing the chicken meat into patties. Patties are susceptible to spoilage due to microbes. This research aims to determine the effect of adding Andaliman on the microbiological quality (TPC test) and organoleptic quality (color, aroma, tenderness, taste) of culling chicken meat patties. The design used in this study is a Completely Randomized Design with a factorial pattern with 2 factors (4x2) and 3 replications. Factor 1 is storage duration (W1 = 24 hours, W2 = 48 hours). Factor 2 is the concentration of Andaliman powder (P0 = without Andaliman addition, P1 = patty + 1% Andaliman, P2 = patty + 2% Andaliman, P3 = patty + 3% Andaliman). The results showed that addition of Andaliman could reduce the total bacterial colony of afkir chicken patty and improve the organoleptic quality of afkir chicken patty. The best treatment in the TPC test was P3W1 (treatmen addition of 3% Andaliman at the storage time of 24 hours) with an average of 20.63 x104 cfu/gr. Furthermore, the addition of Andaliman to the afkir chicken patty has a real effect on the taste, and aroma, but does not have a real effect on tenderness and color. The length of patty storage does not affect the results of the hedonic quality test produced.66 PagesSkripsi Sarjan
The Role of Tax Volunteers in Improving Personal Taxpayers Compliance by Using E-Filing at Low Tax Office of Binjai
No full textTax is an important source of revenue for national development. To
improve taxpayer compliance in submitting the Annual Tax Return (SPT), the
Directorate General of Taxes (DJP) launched the Tax Volunteer program, which
assists taxpayers in using e-filing. This program started in the DJP North Sumatra
I region in 2021, involving students from various universities, including
Universitas Sumatera Utara. Low Tax Office of Binjai has shown positive
performance with an increase in tax revenue and the number of taxpayers
submitting reports. However, despite the increase in reporting, the number of
taxpayers who do not submit their Annual Tax Returns has also risen.
This research aims to examine the role of the tax volunteer program in
improving taxpayers compliance through e-filing at Low Tax Office of Binjai.
This research uses a descriptive qualitative approach with primary and
secondary data sources obtained from the community and Low Tax Office of
Binjai through interviews and documentation.
The research findings indicate that the role of the Tax Volunteer program
in improving taxpayers compliance through e-filing at Low Tax Office of Binjai is
very significant. This program makes it easier for taxpayers to submit their online
annual tax returns, addresses both technical and non-technical issues, and
provides necessary education to ensure that taxpayers file correctly. Although
there are challenges such as technological understanding and network
disruptions, the presence of tax volunteers has a positive impact on improving
compliance. Therefore, this program needs to be continuously developed, with a
focus on enhancing technological literacy and maintaining smooth e-filing

The Development of Android Application for Prediction of Water Quality Index (WQI) in Aquascape Using Gradient Boosting Regression and Improved Grey Relational Analysis (IGRA) Feature Selection
No full textWater is one of the most important elements in an aquascape environment, where small changes in water parameters can affect the Water Quality and environmental balance in an aquascape. There are several ways to check Water Quality, but traditional models such as laboratory testing or the use of IoT sensors often require a lot of money and time, making them less suitable for aquascape users. Therefore, this research was conducted to assist aquascape users in monitoring their Water Quality periodically using Improved Grey Relational Analysis (IGRA) feature selection and the Gradient Boosting Regression (GBR) algorithm XGBoost variant. This research was conducted to develop an Android application that can predict Water Quality Index (WQI) based on manual input from water parameters, namely pH, DO, temperature, TDS, Ammonia, KH, CO2, and light intensity with a dataset consisting of 13,293 lines of data. The XGBoost model built using a training and test data ratio of 80:20 was able to provide excellent results. This is reflected by the evaluation results of the R-squared (R2) metric of 0.9975, Root Mean Squared Error (RMSE) of 0.5440, and accuracy of 99.39%. This research shows that the model can be an aid for aquascape users in monitoring Water Quality more effectively, so as to maintain the balance of the aquascape ecosystem.74 PagesSkripsi Sarjan
