The batik home industry of Kampung Laweyan, Surakarta City did not make efforts to prevent environmental pollution from the wastewater produced. Waste water is discharged into the Jenes river, so that the river becomes polluted and contributes to the pollution of the Bengawan Solo River Basin. The study was conducted at the Environmental Laboratory, Environmental Engineering Study Program, Faculty of Engineering, Surakarta Christian University by conducting the coagulation process of flocculation with the jart test. This study uses variations and dosages of the type of FeSO4 and PAC coagulants with levels of 5% each for 100 ml / sec waste discharge. The results of the research are that before the waste is processed by the coagulation process, the value of BOD = 660.28 mg / l and COD = 1600. After the coagulation process, the efficiency of each type of coagulant is with FeSO4, BOD = 85.63% and COD = 82.67 %. With PAC coagulant, BOD = 90.21%, COD = 88.97%. This shows that the ability of PAC to reduce pollutant parameters is greater than ferrous sulfate.

Abstract Practical work is one of the requirements for taking the final project (thesis) in the Architectural Engineering Study Program. Practical Work Performed by students majoring in Architecture for approximately four (4) months to carry out activities on certain construction projects that are related to the field of architecture such as planning, implementation and supervision of institutions outside the campus in this case the Contractor or Planning Consultant. This research is to find out whether students in carrying out the Final Project also apply the experience gained while carrying out practical work. Based on the above background, we are very interested in proposing and trying to do research with the title "The Role of Practical Work Subjects in Engineering Student Program Final Project". This research was conducted in several stages, namely the survey stage, the data processing stage, and the conclusion drawing stage. In the survey stage, primary data collection is carried out by making a comparison between the Job Training Report and the Final Task Report. Comparisons were made at several universities which according to the plan would be chosen as sampling locations, namely: Bung Karno University, Pancasila University, Indonesian Christian University and "YAI" University. The second stage, data processing is done using the method of raising the sample, the method of analysis, and testing the hypothesis. The last stage was drawing conclusions about the Role of Practical Work Subjects in the Final Project of the Architectural Engineering Study Program.

Maranatha Christian University Bandung is one of the universities in Indonesia that has a Faculty of Information Technology. In the Faculty of Information Technology there is an Informatics Engineering Study Program. The thing that underlies this research is that there is currently no integration between the Practical Work courses and the Final Project courses. For this reason, this research will try to analyze and design one application that will be carried out. The hope of this research is to help the process of submitting practical work topics and students' final assignments so that data is integrated and the recording process is better because it uses a web-based application. This application is a web-based application so it can be used anytime and anywhere.

The aim of waste modelling in aquaculture is to provide tools for simulating input, transformation, output and subsidiary degradation in recipients of organic compounds, nitrogen, and phosphorus. The direct purpose of this modelling is to make it possible for caretakers and water authorities to calculate waste discharge from existing and planned aquaculture activities. A special purpose is simulating outcome of waste water treatment and altered feeding programmes. Different submodels must be applied for P, N, and organics, as well as for the different phases of food and waste treatment. Altogether this calls for an array of co-operating submodels for a sufficient coverage of the options. In all the required fields there is some scientific background for numerical model approaches, and some submodels have been proposed. Because of its multidisciplinary character a synthesized approach is still lacking. Within trout farming this work attempts to establish the different submodels and outlines future possibilities for synthesizing the knowledge to a numerical model.

This introductory book on Geophysics was created to support teaching materials for basic subjects in the Geophysical Engineering Study Program, Physics Study Program, and related Study Programs in addition to other major books. This book introduces the basics of the earth and the structure of the earth, as well as the layers of the earth globally. Furthermore, it is also shown how the relationship between geophysics and other related branches of science within the sphere of geoscience. So that each scientific concept is clearly distinguished, although sometimes there is a very close relationship. In another section, various geophysical methods are described, starting from the basic theory, working principles, approaches and applications. All physical parameters that are applied from each discussion such as seismic method, geoelectric method and IP, gravity method, georadar method, and magnetic method. The hope is that this book can provide benefits for readers and enthusiasts of geoscience.
