ABSTRACT
Concrete is a complex-composite material. Semen Portland or other hydraulic types of cements, fine aggregates, coarse aggregates, and water, with or without additional substance, are the major materials in making concretes. In this time, the concrete cost more expensive, despite of many infrastructure development that caused higher concretes demand, the increased of concretes cost also caused by the cements high-price as a result of higher PPN value 11% for cement production cost. Cement is highly affected the concrete cost, it is because cement is the major material in forming the concrete that is more expensive than other types of materials. Therefore, it is important to reduce the cement content to press the cost of concrete. This study done by utilizing the variation of added admixture additon superfluid L to reduce the use of cement and water contents by using trial and test method, and slump that was planned 10±2 cm. The reduction of cement for about 5% and 10% from the total weight of cement also there are 4 added variation of content of admixture additon superfluid L, they are 0.5%, 1.0%, 1.5%, dan 2.0% from the cement weight with FAS still about 0,5. According to the test of concrete characteristics such as compressive strength testing, porocity testing, and elastic modulus testing, generally by having more PSA and admixture additon superfluid L, the quality of concrete getting lower from the view of compressive strenght, porocity,or even elastic modulus.

The environment is one of the sectors that has undergone a transformation since the Job Creation Law was passed. A number of clauses in Law No. 32/2009 were removed and amended by the Cipta Kerja Law. One of them is the elimination of Environmental Permits and replaced with environmental approvals that are integrated with business licensing. Government Regulation No. 22 of 2021 on the Implementation of Environmental Protection and Management is a derivative regulation of the Cipta Kerja Law. Many stakeholders are still unaware of the government regulation even though it has been in effect for two years. Therefore, the purpose of this article is to provide a brief explanation of how environmental approvals are issued. The method is normative legal research through a literature study of the mechanism for issuing environmental approvals listed in Government Regulation No. 22 of 2021. This research uses content analysis and flow charts as analysis techniques. The mechanism for issuing environmental approval has been regulated in detail in Government Regulation No. 22 of 2021 starting from self-screening by the person in charge of the business and/or activity, preparation of environmental documents, the process of examining and/or assessing environmental documents in the form of Environmental Impact Analysis (EIA) and Environmental Management Efforts and Environmental Monitoring Efforts (UKL-UPL) forms and Issuance of Environmental Approval.

Вопросы обеспечения безопасности окружающей среды в результате развития промышленных предприятий всегда очень актуальны. Развитие технологий и применение промышленными предприятиями в технологическом процессе различного вида оборудования вызывают реальную угрозу загрязнения водоемов сточными водами, которые содержат вредные и опасные вещества. Это в свою очередь может нанести колоссальный вред флоре и фауне водоемов. Поэтому очень важно определить возможные последствия техногенных чрезвычайных ситуаций, что позволит предусмотреть требуемые меры защиты и снизить вероятность загрязнения окружающей среды, в частности водоемов. Для этого используются различные методы математического моделирования. Математические модели с определенной погрешностью позволяют упрощенно описать движение водного потока. Рассмотрены одни из основных математических моделей структуры потоков. Показано на основании каких критериев осуществляется выбор той или иной модели. Представлен способ расчёта концентраций и времени пребывания вредных веществ на определенном участке водного пространства при залповом сбросе неочищенных сточных вод.

Цифровизация распределенных технологических объектов в нефтяной и газовой промышленности до недавнего времени подразумевала оснащение объекта постоянным электропитанием. Но в последние годы возрастающие требования по промышленной безопасности, технические, административные и экономические сложности подведения внешнего электропитания к распределенным объектам привели к необходимости создания систем телемеханики, способных работать от источников электропитания, использующих возобновляемые ресурсы (солнечную или ветровую энергию). К этой категории относятся системы телемеханики для кустов газовых скважин, одиночных скважин, одно – и двухниточных газопроводов-отводов. Современный уровень развития систем интеллектуальных управления технологическими процессами позволяет диспетчерам иметь обширную первичную информацию для решения задач управления как в штатном, так и (правда, не всегда) в нештатном режимах. Однако это еще не гарантирует правильность или наибольшую эффективность принимаемых решений. В работе в качестве примеров, для которых создается система поддержки принятия решений, взят технологический процесс магистрального транспорта газа, осуществляемый предприятием по транспорту газа, и сбора газа по межпромысловому коллектору газового месторождения, осуществляемый подразделением газодобывающего предприятия.
Until recently, digitalization of distributed technological facilities in the oil and gas industry meant equipping the facility with constant power supply. But in recent years, the increasing requirements for industrial safety, technical, administrative and economic difficulties of supplying external power supply to distributed objects have led to the need to create telemechanics systems capable of operating from power sources using renewable resources (solar or wind energy). This category includes telemechanics systems for clusters of gas wells, single wells, one - and two-line gas lateral pipelines. The modern level of development of systems for intelligent control of technological processes allows dispatchers to have extensive primary information for solving control problems both in normal and (albeit not always) in abnormal modes. However, this does not yet guarantee the correctness or the highest efficiency of the decisions made. In the work, as examples for which a Decision Support System (DSS) is being created, the technological process of main gas transportation carried out by a gas transport enterprise and gas collection through the interfi eld reservoir of a gas field, carried out by a subdivision of a gas production enterprise, is taken.

Промышленные АСУ характеризуются огромными объемами информации, которую необходимо хранить, обрабатывать и анализировать. Одним из мощнейших ресурсов для хранения являются базы данных, в частности реляционные базы данных. С ростом объемов обрабатываемой информации, растут IT предприятия, количество решаемых задач и, следовательно, количество сотрудников. В больших командах появляются проблемы с управлением изменениями на разных средах (Development, Test, Stage или Pre-Production, Production), а также переносом изменений между ними. Целью данной работы является унификация методов управления изменением структуры баз данных на разных средах и описание единого алгоритма для переноса изменений между ними. Особенностью разработки является возможность использования алгоритма в компаниях с повышенным уровнем безопасности доступа к данным, исключающим возможность подключения разработчиков к производственным средам. В статье рассмотрены базовые методы работы со словарем данных Oracle, лежащие в основе разработки логики построения алгоритма автоматизации создания сценариев изменения структуры баз данных.
The modern world is characterized by huge amounts of information that must be stored, processed and analyzed. One of the most powerful storage resources is databases, in particular relational databases. With an increase in the volume of information processed, IT enterprises, the number of tasks to be solved and, consequently, the number of employees grows. Large teams have problems with managing changes in different environments (Development, Test, Stage or Pre-Production, Production), as well as transferring changes between them. The purpose of this work is to unify methods for managing changes in the structure of databases in different environments and to describe a single algorithm for transferring changes between them. A feature of the development is the ability to use the algorithm in companies with an increased level of data access security, which excludes the possibility of developers connecting to production environments. The article discusses the basic methods of working with the Oracle data dictionary, which underlie the development of logic for building an algorithm for automating the creation of scripts for changing the structure of databases.

Описан процесс определения актуальных негативных последствий при реализации защиты информации, который предоставляет комиссии по моделированию угроз дополнительные инструменты для сбора и анализа экспертных оценок. Разрабатываемый подход заключается в классификации групп негативных последствий по характеру направленности действий предполагаемых нарушителей, ранжировании полученных данных по степени влияния рисков на субъект и последующем нахождении усредненного итогового мнения экспертов, об актуальности негативных последствий за счет нахождения медианы Кемени. В рамках разрабатываемого подхода такие процедуры позволят повысить оперативность и эффективность в процессе моделирования угроз за счет построения взаимосвязей целей потенциальных нарушителей безопасности и возможных негативных последствий.
The process of determining the actual negative consequences in the implementation of information protection is described, which provides the commission for modeling threats with additional tools for collecting and analyzing expert assessments. The approach being developed consists in classifying groups of negative consequences by the nature of the direction of actions of alleged violators, ranking the data obtained according to the degree of influence of risks on the subject and then finding the average final opinion of experts, on the relevance of negative consequences by finding the Kemeny median. Within the framework of the developed approach, such procedures will increase the efficiency and effectiveness in the process of threat modeling by building interrelationships between the goals of potential security violators and possible negative consequences.
