Abstract

The Kapuas River Basin (DAS) has great benefits for the community, especially for clean water needs. The community's need for water starts from the need for drinking water to the need for sanitation. But along the flow of the Kapuas River has experienced pollution. To prevent and improve river water quality, it is necessary to test the water quality in the Kapuas River area and find out the causes of pollution in the research location. This research was conducted in Sintang City as the upstream watershed and Pontianak City as the downstream watershed. Determination of water quality status is carried out using the STORET method. The results obtained, the water of the Kapuas River in the city of Pontianak is classified as heavily polluted. Meanwhile, the Kapuas River water in Sintang City is classified as moderately-severely polluted. The source of the pollutant comes from domestic waste. Efforts to prevent and improve water quality can be carried out by educating the local community regarding water quality and building a Communal WWTP to treat this waste.

Abstract

Pontianak, sebagai Ibu Kota Provinsi Kalimantan Barat, berdasarkan peta zonasi gempa termasuk wilayah dengan tingkat risiko gempa sangat rendah. Meskipun demikian, perkembangan terkini menunjukkan bahwa perencanaan struktur di daerah berisiko gempa rendah tetap perlu mempertimbangkan beban gempa sebagai bagian dari desain yang komprehensif. Penelitian ini mengkaji perencanaan struktur tahan gempa pada bangunan strategis berbasis fungsi akademik, dengan studi kasus pada suatu gedung pendidikan yang berlokasi di kawasan perkotaan. Perencanaan dimensi elemen struktur mengacu pada SNI 1726-2012 tentang ketahanan gempa untuk memastikan kemampuan bangunan dalam menahan kombinasi beban mati, hidup, dan gempa. Analisis dilakukan menggunakan program ETABS untuk mengevaluasi efisiensi dimensi struktur dalam menahan beban yang bekerja. Hasil penelitian menunjukkan bahwa meskipun risiko seismik di Pontianak rendah, penerapan standar gempa tetap menghasilkan elemen struktur yang efisien, memenuhi persyaratan teknis, dan meningkatkan kesiapsiagaan struktural terhadap potensi beban dinamik. Studi ini menegaskan pentingnya integrasi prinsip tahan gempa pada bangunan strategis, bahkan di wilayah dengan zonasi risiko rendah, sebagai langkah antisipatif dalam mitigasi bencana.

Abstract

In the proper category, buildings must stand upright, sturdy and strong for a long period of time and no settlement occurs. Panca Bhakti University (UPB) is currently building campus facilities and infrastructure to meet the growing number of students, one of which is the rectorate building. Before the rectorate building is put into operation, an initial investigation is needed to find out whether or not settlement has occurred in the building structure. Settlement is a decrease in subgrade elevation caused by a layer of soil that is loaded on it, causing the soil beneath to experience an increase in stress. The implementation of the research is by making observations and measuring settlement behavior with a waterpass. The purpose of this investigation is to identify and monitor settlement behavior and determine settlement values ​​that occur in the structure of the Panca Bhakti University rectorate building. The results showed that the highest settlement value occurred at observation points T2-LT.4 and T6-LT.4 with a value of 5 mm. At the observation points T6-LT.1, T1-LT.4, and T3-LT.4 the height difference was 3 mm. While the observation points T1-LT.1, T2-LT.1, T3-LT.1, T4-LT.1, T5-LT.1, T4-LT.4, and T5-LT.4 with a value of 0 , it can be said that there is no difference in height. The average height difference value of all observation points is 1.58 mm. Settlement data is needed so that the risk of structural damage to buildings can be identified early. With this research data, it can be used as a justification for the reliability of the building as well as reference data for monitoring the maintenance of the Panca Bhakti University rectorate building in the future.
