Abstract

In the effort of public welfare, the government through the provision of boards such as residential houses, either through private parties or SOEs, often gets the location of the land base in the form of soft land or ugly carrying capacity, which impact on maintenance and repair costs far greater than the cost of purchase. Researchers studied through the stabilization of soil with cement materials and soil mixed variations that occur, so that the soil as a buffer building is known strength or carrying capacity. On improving the strength of the road body with soil stabilization through the CBR test, it can be obtained an increase in soil bearing capacity. Sondir testing for the foundation design data either through conical resistance (qc) or by friction can be obtained by the base area of the foundation foot. If the value of qc is large then the footprint of the foundation foundation, especially shallow foundations will be small. With soil and cement stabilization studies in the laboratory, with different variations and durations can be obtained a reference to the increase in the carrying capacity of the shallow foundation footing and the required thickness of the layer based on the pattern of voltage distribution with the mathematical equation y = 0.7935x - 6.79 where y = power support for soil (kg / cm2), and x =% plus cement and R = correlation.Kata kunci: Tanah, Semen, Daya Dukung, Sondir.

Abstract

Darul Hikmah Mosque is a building located inside Politeknik Negeri Semarang as a place of worship for all campus residents, and people who live around the area. The prayer activity is preceded by the Wudu. In order for Wudu to be carried out perfectly, sufficient quantities of water are needed. The lack of pressure and discharge of Wudu tap water, when used simultaneously, becomes a constraint that is the water pressure decreases. The purpose of this study is to determine the factors causing the lack of water discharge or pressure as required in SNI 03-7065-2005. The research method is quantitative descriptive by evaluating the performance of the existing water supply system and using a discrepancy model by comparing the evaluation results with existing data to find discrepancies. Evaluation results indicate that the factors that cause the lack of water pressure are the roof tank height is less than ideal for water distribution with gravitational power, and the volume of available water is not sufficient

Abstract

Kawasan Industri Genuk di Kota Semarang, disamping memberikan keuntungan dalam aspek ekonomi, juga memberikan beban bagi lingkungan, seperti penggunaan sumberdaya air bersih yang sebagian besar masih bersumber dari air tanah. Pengambilan air tanah yang tidak memperhatikan kondisi cekungan air tanah mengakibatkan intrusi air laut, terutama di wilayah akuifer rendah yang memiliki debit air tanah kurang dari 1,3 liter/detik, sehingga menurunkan kualitas air tanah akibat dari intrusi air laut. Baku mutu air minum (PERMENKES. 492/MENKES/PER/IV/2010) telah mensyaratkan bahwa air tanah dapat digunakan sebagai air minum apabila kandungan klorida (Cl) di dalam air tanah kurang dari 250 mg/L. Pada umumnya kondisi air tanah yang telah tercemar akibat dari intrusi air laut, nilai kandungan klorida (Cl) air tanah tersebut lebih dari 250 mg/L dan berdampak pada tidak efektifnya kegiatan di kawasan industri. Penelitian tentang intrusi air laut terhadap air tanah pada akuifer tertekan (sumur bor) menggambarkan bahwa pada tahun 2013, luasan wilayah pesisir di Kota Semarang yang berpotensi mengalami intrusi air laut sebesar 5.920,96 ha atau sekitar 54,5 % dari luas wilayah penelitian sebesar 10.448,6 ha terutama yang memiliki elevasi tanah sampai dengan 3 mdml (radius 4 km dari garis pantai) meliputi sebagian wilayah Kecamatan Semarang Barat, Kecamatan Semarang Tengah, Kecamatan Semarang Utara dan Kecamatan Genuk. Tantangan bagi kawasan industri dalam memenuhi kebutuhan air bersihnya perlu strategi yaitu dalam pengelolaan sumberdaya air di kawasan industri diperlukan keselarasan aspek ekonomi dan lingkungan, pendekatan bisnis dalam pengelolaan lingkungan, dan penerapan produksi bersih.Kata kunci: Kawasan industri berwawasan lingkungan, air tanah, produksi bersih.

Abstract

Company value is important because it influences the company's survival in the future. Many variables can influence company value, such as disclosure and capital structure management. Disclosure is carried out to provide information to stakeholders about the company, one of which is disclosure of Corporate Social Responsibility (CSR) which is a responsibility in terms of economic, environmental and social aspects. Capital structure management is carried out to achieve a balance between liabilities and equity so as to maximize company value. This research aims to determine the influence of Corporate Social Responsibility, Profitability and Capital Structure on Company Value in the current Covid 19 pandemic era. This research uses quantitative descriptive research. The population and sample in this study are pharmaceutical companies listed on the Indonesia Stock Exchange for the period 2018 - 2022. The data used is secondary data from annual financial reports on the Indonesia Stock Exchange. This research uses data analysis techniques such as multiple regression analysis and SPSS as tools to process and test data. The results of this research show that partially CSR has no significant effect, ROE has a significant effect and DER has no significant effect on company value. Meanwhile, simultaneously CSR, ROE, and DER have a significant effect on company value.

Abstract

This study explores the role of Artificial Intelligence (AI) as a catalyst for transforming operational efficiency and disrupting product innovation within the startup ecosystem. Using a qualitative literature review method, data were sourced from 20 rigorously selected scholarly articles out of an initial 40 identified on Google Scholar for the 2004-2024 period. The findings reveal that AI significantly enhances operational efficiency through process automation, data analysis, and accurate market forecasting, as exemplified by Gojek and Halodoc. Additionally, AI facilitates personalized and customer-centric product innovations, as demonstrated by Ruangguru. Despite its clear benefits, challenges such as limited human resources, high implementation costs, and privacy regulations must be addressed. This research underscores the importance of collaboration between startups, the government, and academic institutions to maximize AI's potential in supporting business sustainability and global competitiveness for startups in Indonesia.

Abstract

Food security is one of the main keys to realizing the welfare of the people in Indonesia. Currently, Indonesia is still experiencing serious food security problems, especially rice availability. Based on the Central Bureau of Statistics 2024, the highest level of insecurity across Indonesia is in East Nusa Tenggara Province, with a value of 14.68%. Meanwhile, the population in East Nusa Tenggara Province is quite large, with more than 5 million people. If the level of vulnerability is at the highest rank, it can be said that East Nusa Tenggara Province has very low food security. This study aims to analyze the effect of rice harvest area, rice productivity, and population density on food security in 21 districts and 1 city of East Nusa Tenggara Province from 2018 to 2023. This study uses secondary data in the form of panel data. The sample used in this study is data from 22 districts and cities in East Nusa Tenggara Province for 6 periods, with details, namely 22 x 6 = 132. This study found that simultaneously, the variables of rice harvest area, rice productivity, and population density in East Nusa Tenggara Province had a significant effect on food security. While partially obtaining results, namely the variable area of rice harvest and rice productivity, there is a significant effect on food security. The total population variable has no significant effect on food security.
