Domestic and industrial waste has been identified as containing many heavy metals as indicators in water bodies. The research aims to analyze the heavy metal quality of Surabaya river water and predict its quality as sustainable raw water. This research was located in the Surabaya River in the Karangpilang IPAM intake segment. The research method uses a forecasting approach based on primary data using a purposive sampling method and laboratory tests. The results showed that the heavy metal concentrations of Cr = <0.0117, Cu = <0.0090 and Pb = 0.001-0.010 did not exceed the quality standards based on class I classification of PP No. 22 of 2021 concerning Implementation of Environmental Protection and Management. The concentrations of heavy metals Cr and Cu are still lower than the detection limit of the test equipment, so forecasting is only carried out on the heavy metal Pb. The simulation results for the next 10 years still get results that meet the quality standards, but when compared with the actual ones with MAPE validation, there are several values that exceed the standards with very bad forecasting levels.

The frequency of natural disasters keeps increasing from time to time. The catastrophes from the events affect millions of people around the world. It demands the involvement of architects in the design and planning difficulties associated with rebuilding post-disaster areas and cities. However, there is a continuing lack of architects who are capable of handling the damage left behind by devastating natural disasters like floods, fires, earthquakes, typhoons, and tsunamis. In addition, there is a shortage of architectural students who are interested in this crucial matter. Targeting architecture faculties and students, this study discusses the architects’ role in the humanitarian subject. The objective is to figure out the level of awareness and exposure to this topic at the higher education level. It was done by examining the involvement of architecture faculties and students in humanitarian architecture through mixed qualitative and quantitative methods. This study proposes a way to shed light on humanitarian architecture to alert architecture faculties and students to the growing need for help and support in reconstructing communities damaged by catastrophes. It also provides an understanding of how to offer assistance while respecting the culture, identity, and needs of the affected people.

Recently, technological developments have become increasingly rapid thus, companies must be able to compete by increasing efficiency and effectiveness in order to achieve productivity through system development. Currently, PT Bina Pertiwi Surabaya Branch has applied an information system in its process flow, namely System Application and Product (SAP). SAP is an information system in the form of software with various taskbar menus that function to process data. One of the taskbar menus that is commonly used is HR (Human Resources), especially regarding company expenditure reports, all matters with vendors and customers, as well as employee leave and overtime input. The purpose of this research is to analyze expense posting procedures using SAP. This research uses objects in the implementation of SAP and the parties involved. The results of this research show that the application of SAP makes it easier for employees to process data. However, problems were still found in the expense posting procedure. This obstacle comes from external parties, namely the WO (Work Order) number not appearing which can hinder the progress of the expense posting procedure. So, a solution is provided to resolve these obstacles by carrying out 10 resolution steps which include, difficulty analysis, open communication, updating or improving procedures, training and development, use of technology, collaborative teams, managing change, periodic evaluation, providing support, and flexibility.
近来，技术发展日新月异，因此，企业必须通过提高效率和效益来增强竞争力，从而通过系统开发实现生产力。目前，PT Bina Pertiwi Surabaya 分公司已在其流程中应用了信息系统，即系统应用和产品（SAP）。SAP 是一种软件形式的信息系统，其任务栏上的各种菜单具有处理数据的功能。其中一个常用的任务栏菜单是人力资源（HR），特别是关于公司支出报告、与供应商和客户的所有事务，以及员工休假和加班输入。本研究的目的是分析使用 SAP 的支出过账程序。本研究使用 SAP 实施过程中的对象和相关方。研究结果表明，SAP 的应用使员工更容易处理数据。然而，在费用过账程序中仍然发现了一些问题。这种障碍来自外部，即 WO（工单）编号未出现，这会阻碍费用过账程序的进展。因此，我们提供了一个解决方案，通过 10 个解决步骤来解决这些障碍，其中包括： 困难分析、坦诚沟通、更新或改进程序、培训与发展、使用技术、协作团队、管理变革、 定期评估、提供支持和灵活性。

One of the causes of the decline in sea water quality is due to industrial activities near sea waters, one of which is Steam Power Plants where the cooling system activity process of the generating equipment becomes a problem because it is thrown into the sea at high temperatures. Based on this, it is necessary to calculate the status of sea water quality in order to find out whether sea water quality has decreased due to the PLTU's activities. The aim of this research is to determine the quality profile of sea water and determine the impact of activities in the surrounding waters at several monitoring points around the waters of the Steam Power Plant. The way to determine or status method for water quality is with a pollution index based on Decree of the Minister of Environment Number 115 of 2003. Water quality can be assessed based on the classification of pollutant indicators, the pollutant index value around the Steam Power Plant in 2020 Quarter II is 7.86 at the point 6. Meanwhile, in 2021 and 2022 there will be a decline in every quarter and at all points, for determining quality status refers to Minister of the Environment Regulation No. 2003 No. l115, in 2020 Quarter II, the quality status of sea water around the waters of the Steam Power Plant was included in the moderately polluted category and in both 2021 and 2022 the quality status of sea water around the waters of the Steam Power Plant was included in the lightly polluted category.

The main issue in the implementation of precast concrete systems lies in the connections. The connections in precast systems must possess the strength to withstand the occurring loads. One of the methods used for connecting precast concrete is the dry connection method. To test the connections of precast beam-columns, a quasi-cyclic loading test is utilized, which generates data on the relationship between load (P) and displacement (∆). The test results indicate that test specimens using 4 anchors have a higher maximum capacity compared to those using 2 anchors. Additionally, the cycles that occur in the test specimen with 2 anchors are longer than those in the specimens with 4 anchors and monolithic specimens. The peak load is achieved by the test specimen with 4 anchors, reaching 1488 kg at a displacement of 18 mm, specifically at a 2% drift. Both the monolithic and 4-anchor test specimens have the same drift, reaching 2%. However, the longest cycles occur in the test specimens with 2 anchors, reaching a 4% drift. Consequently, it can be concluded that the test specimens with 4 anchors have a greater capacity and shorter cycles compared to those using 2 anchors and the monolithic specimens.
