Food security and community economic empowerment are major challenges in many rural areas, including Sukolilo Village. This research aims to develop and analyze the effectiveness of an aquaponic system, a combination of hydroponics and fish farming, as an innovative sustainable solution. The methods used include observation, experimentation, and interviews with the local community. The results showed that the aquaponic system is able to increase agricultural productivity with better water use efficiency and provide economic benefits through crop diversification, namely vegetables and fish. In addition, the system is proven to be environmentally friendly as it utilizes organic waste from fish as plant nutrients, reduces the use of chemical fertilizers, and optimizes local resources. The implementation of the aquaponic system in Sukolilo Village not only improves food security but also opens up new business opportunities for the community, thus contributing to the improvement of local economic welfare. It is hoped that this model can be replicated in other areas as part of a sustainable agriculture-based economic development strategy.

Suitability to the plantation soil type is very important, because can increase the productivity of plantation crops. From the observation in Boyolali, there are several types of soil, includingregosol, Andosol, litosol, mediterranean, grumosol. Geographic Information Systems (GIS) is one of the appropriate steps to present the spatial aspect (spatial). SIG has benefits that can be used to analyze the suitability of land in accordance with predetermined parameters, the type of soil, crop types and data sub-district in Boyolali. This study aimed to analyze the suitability of the soil to increase the productivity of plantations in Boyolali using Geoprocessing techniques. Following the Geoprocessing techniques in all sub-districts boyolali, most soil types are regosol and mediterranean contained in 15 districts, so it can be concluded that the type of plants should be planted in the district is coffee, Kina, Cinnamon, Crops, Fruits.

PT. Fajar Lestari Sejati was a company engaged in the field of door and window accessories, offering its products from store to store, small projects, and even entering large-scale projects. PT.

Fibrosis hati merupakan kondisi yang berpotensi berkembang menjadi sirosis atau kanker hati jika tidak terdiagnosis dengan tepat. Prosedur biopsi hati yang invasif sering digunakan dalam diagnosis, namun memiliki risiko dan keterbatasan biaya. Penelitian ini bertujuan untuk membandingkan kinerja model deep learning, yaitu Convolutional Neural Network (CNN), Long Short-Term Memory (LSTM), dan Feedforward Neural Network (FNN) dalam klasifikasi fibrosis hati menggunakan citra medis. Metode yang digunakan adalah evaluasi kinerja model berdasarkan metrik akurasi, presisi, recall, F1-score, dan loss pada dataset citra medis fibrosis hati. Hasil penelitian menunjukkan bahwa CNN memberikan kinerja terbaik dengan akurasi 98%, diikuti oleh LSTM dengan akurasi 97%, dan FNN dengan akurasi 80%. CNN unggul karena kemampuannya dalam mengekstraksi fitur spasial secara otomatis dari citra medis, sementara LSTM lebih cocok untuk data sekuensial dan FNN terbatas dalam menangani data citra kompleks. Penelitian ini menyimpulkan bahwa CNN lebih efektif dalam klasifikasi fibrosis hati dan dapat menjadi alternatif non-invasif yang lebih efisien dibandingkan metode konvensional seperti biopsi. Teknologi ini berpotensi mempercepat diagnosis fibrosis hati dengan akurasi tinggi dan tanpa risiko komplikasi invasif.

Clean water is a fundamental necessity for public health, as water contamination can lead to various health problems, such as gastrointestinal infections, skin diseases, and other health issues. Screening for water contamination by Escherichia coli bacteria and Corynebacterium spp. is essential to ensure water quality remains safe. This community service activity was conducted in the Duri Kosambi area, focusing on education and water quality testing. The program included planning educational sessions on the risks of water contamination, implementing screenings using colony-forming unit (CFU) parameters to detect Escherichia coli and Corynebacterium spp., and evaluating results to provide preventive recommendations. The findings revealed variations in contamination levels across locations, with some meeting cleanliness standards, while others, such as B04, showed extreme contamination. This activity highlights the importance of community education, regular water quality monitoring, and water treatment to prevent health risks. Collaboration among communities, governments, and health organizations is crucial to maintaining sustainable access to high-quality clean water.

The purpose of the study is to determine and test whether partially the size of the company, the age of the company, is significant to the audit tenure and audit delay and also to test whether the audit tenure is able to mediate the effect of reducing the effect of the relationship between company size, company age and audit delay. Secondary quantitative financial statements of 48 Indonesia Stock Exchange companies in the property and real estate sector. Samples were obtained by 48 companies by purposive sampling. Analysis with path analysis software SPSS v24. The company's age results are the only significant variable to audit delay. While audit tenure, partial company size is not significant to audit delay, and audit tenure cannot increase influence as an intervening variable.

This research aims to explore a web-based payroll information system. The location of the research is at D'Soccer Ungaran Football Stadium, a mini soccer field rental business. From observations, several risks were found in salary management, including: 1) The risk of salary calculation errors due to conventional methods. 2) Risk of corruption and data loss because there is no database yet. 3) Employee salary reports are still prepared manually, less efficient. Based on this problem, the author designed a payroll system with a net method for withholding income tax 21. The use of this method aims to help employees reduce dissatisfaction due to tax deductions. The results of the effectiveness test showed that the new system was more effective than the old system, with a score ratio of 11:20 and performance effectiveness of 44%:80%.
