Abstract

The use of concrete in construction continues to increase, so innovation in making concrete continues to grow. One of the innovations used in this study is to use additives to analyze the effect of concrete compressive strength on the use of historical beach sand and chemical additives (Plastimen-VZ) as concrete mixes using Mix Design SNI 2834-2000. Testing of the compressive strength of concrete was carried out at 3 and 7 days of age with a reference to normal concrete control of 24.90 MPa or equivalent to K-300 and the number of samples consisted of 18 samples with the added chemical Plastiment-VZ (Sika) 0%, 0.40 %, 0.80%. The results of the study using historical beach sand and Plastimen-VZ (Sika) meet the specifications for use as a concrete mix with a normal concrete control reference of 24 MPa with a compressive strength value of 24.76 MPa. The results of the compressive strength of concrete with a mixture of beach sand and Plastimen-VZ (Sika) 0.40% aged 3 days obtained an average of 24.99 MPa. The results of the compressive strength of concrete with a mixture of beach sand and Plastimen-VZ (Sika) of 0.80% aged 7 days obtained an average of 25.03 MPa.

Abstract

Air merupakan sumber daya yang sangat penting, namun pengelolaanya sering menghadapi tantangan, terutama dalam hal penyerapan air hujan. Dusun Satu A Desa Banjar Kecematan Air Joman Kabupaten Asahan Provinsi Sumatera Utara menghadapi tantangan dalam pengelolaan air hujan dikarenakan Dusun Satu A memiliki ketinggian tanah yang lebih rendah dari pada dusun lainnya. Untuk mengatasi masalah ini maka lubang biopori sebagai solusi yang efektif. Lubang biopori adalah Teknik konservasi air yang melibatkan pembuatan lubang-lubang di tanah untuk meningkatkan infiltrasi air hujan sehingga mengurangi genangan air dan mempercepat penyerapan air ke dalam tanah. Selain itu, biopori dapat mengubah sampah organic menjadi kompos dan meningkatkan kesuburan tanah.

Abstract

Di seluruh dunia, masalah kesehatan dan keamanan data menjadi semakin umum seiring dengan kemajuan era digital. Oleh karena itu, penting untuk memahami bahwa kemajuan teknologi dapat digunakan untuk menyampaikan pentingnya hal-hal ini kepada masyarakat umum. Desa Banjar berada di Kecamatan Air Joman, Kabupaten Asahan. Diharapkan dapat berfungsi sebagai alat pembelajaran dan pengajaran baru yang membantu orang belajar lebih banyak tentang Perangkat Desa dan bagaimana mereka dapat menggunakan teknologi Internet, yang pada akhirnya akan digunakan oleh semua orang. Untungnya, sosialisasi sangat membantu masyarakat menjadi lebih sadar tentang pentingnya kesadaran keamanan siber dan kejahatan siber. Dalam kegiatan workhsop ini, peran masyarakat adalah untuk memancarkan kualitas materi yang disajikan, dengan tekanan betapa pentingnya bagi peserta untuk memahami informasi dan konsep yang disajikan selama acara. Selain itu, tujuan pendidikan ini adalah untuk meningkatkan pengetahuan baru dalam kelompok. Diharapkan pemahaman yang lebih baik tentang ancaman yang terkait dengan kesehatan global dan pentingnya melindungi data pribadi.

Abstract

Water is one of the most vital sources of livelihood for all living things on earth. However, not all people have the ability to process water. Datuk Bandar District is one of the areas that has a large number of residents and facilities for schools, offices and other public facilities. In this study, we analyze the demand for domestic and non-domestic clean water in Datuk Bandar District for the next 20 years by projecting the need for population growth until 2041 based on data from the Central Statistics Agency. The method used in this study is the method of arithmetic, geometry, and least square. From the results of the analysis, the projected population of Datuk Bandar Subdistrict in 2041 using the geometric method is 81,670 people and the projected clean water needs of 85,105 l/second, while for now the production capacity of PDAM Tirta Kualo for Datuk Bandar Subdistrict is in WTP II service, namely of 90 l/sec. so that until 2041 the need for clean water for Datuk Bandar District is still fulfilled.

Abstract

The gourami (Osphronemus goramy) fish is a freshwater fish commonly found in Asia and widely cultivated by fish farmers or local inhabitants. The survival rate of gourami fish from egg to larva and juvenile stages is very low, at approximately 50%. Several factors, such as unstable environmental conditions, poor water quality, and fungal growth on the eggs, cause this. Typically, synthetic medications or natural materials such as betel leaves and others are used to improve gourami fry's survival rate. In this study, the researchers attempted to apply ozone plasma technology dissolved in water to observe the egg hatchability of gourami fish. This study aims to apply technology in fisheries and aquatic sciences. The results of the study show that ozone technology can be applied to observe larval survival, with the highest survival rates found in the 10-minute and 15-minute ozone treatments, both achieving 100% hatchability, with larval survival rates of 86.67% and 96.66%, respectively.
