The use of concrete for various building constructions has been widely used, both as a building structure and also for transportation purposes, especially for concrete roads. Nanga Jemah Village is one of the villages located in Boyan District, Kapuas Hulu Regency which has potential in the field of building materials. The use of aggregates originating from Nanga Jemah has often been done, but until now no one has investigated this type of aggregate as a concrete-forming material, especially for the manufacture of concrete rebate roads. The aggregates used in this study are aggregates derived from Nanga Jemah, both fine aggregates and coarse aggregates by comparing the use of commonly used materials. The purpose and objective of this research are to develop the potential of the area in the form of materials originating from the village of Nanga Jemah so that they can be used as concrete-forming materials, especially for the construction of the Rabat Beton road.

This study aims to: (1) produce 3-dimensional (3-D) animated video-based learning media in the Engineering Mechanics course. (2) Knowing the feasibility level of 3-dimensional (3-D) animated video-based learning media in the Engineering Mechanics course. This research employed to research and development methods to develop learning media based on 3-dimensional (3-D) animation videos. The learning media development procedure is carried out through (1) the preliminary study stage, which consists of a literature review and a field study; and (2) the development stage, which is carried out by making a draft of a model design that is divided into three parts, including: compiling materials, making scripts, preparing 3-dimensional (3-D) animation videos, and editing animation videos. Furthermore, validation of assessments by material experts, media experts, and learning experts, as well as limited trials to assess the feasibility of the learning media created; (3) The evaluation stage is the final stage of the development process related to the final model of 3-dimensional (3-D) animated video-based learning media in the Engineering Mechanics course.

The use of SCC (Self Compactibility Concrete) concrete in Indonesia is increasing in the field, especially for a variety of buildings that require large compaction speeds or use concrete that can compact itself. SCC Concrete Technology in the construction industry is growing, especially in meeting the needs of the construction world. Added material is an alternative material used to increase the strength characteristics of the concrete. Likewise the addition of glass powder waste, and bauxite waste in making SCC concrete is expected to increase the compressive strength concrete. Fresh concrete, which belongs to the self-compacting concrete (SCC) group, has a very high slump value (more than 20 cm), so measurements with cone abrams are no longer effective. The use of these materials as substitute materials and added based on the thought to utilize glass waste and , bauxite waste in order to reduce the impact of environmental pollution and provide economic value. This study uses glass powder as glass waste and bauxite waste as added material for cement. This study uses four kinds of mixed compositions, namely 0% (ordinary concrete); 2.5% mixture; 5% and 7.5% by weight of cement as added material from glass waste and bouksit waste, where each composition consists of 3 cylindrical specimens with a diameter of 15 cm and a height of 30 cm. Until now there has never been any research from mananpun to test the 2 (two) mixtures, therefore we want to test it so that glass waste and bauxite waste are not wasted and can be reused, especially in making SCC concrete. From the research results it was found that the maximum slum cone test results were in the 2.5% variation that is equal to 44.3 cm, while the minimum at 0% was 29.3 cm. The maximum compressive strength at the age of 3 days is 455,418 kg / cm2 for variations of 7.5% while the minimum is at a variation of 2.5% of 200.469 kg / cm2 at 7 days of concrete.

Perusahaan harus memaksimalkan kinerja karyawanya guna untuk menjawab tantangan persaingan yang ketat di dunia industri. Penurunan kinerja yang terjadi pada karyawan menjadi fenomena dalam penelitian ini. Dengan beragamnya faktor yang mampu mempengaruhi kinerja, peneliti menggunakan variabel kompensasi, komunikasi dan perilaku disiplin sebagai mediasi terhadap kinerja. Metode peneltian ini merupakan penelitian kualitatif, data bersumber dari 100 responden dengan metode pengumpulan menggunakan kuesioner. Metode untuk analisa datanya menggunakan aplikasi smartPLS 3.0. Hasil dari penelitian ini adalah kompensasi berpengaruh terhadap perilaku disiplin, perilaku disiplin berpengaruh terhadap kinerja, komunikasi berpengaruh terhadap kinerja, dan perilaku disiplin mampu memediasi kompensasi terhadap kinerja. Companies must maximize the performance of their employees in order to answer the challenges of intense competition in the industrial world. The decline in performance that occurs in employees is a phenomenon in this study. With a variety of factors that can affect performance, researchers use the variables of compensation, communication and discipline behavior as a mediation on performance. This research method is a qualitative research, data sourced from 100 respondents with the collection method using a questionnaire. The method for analyzing the data is using the smartPLS 3.0 application. The results of this study are compensation has an effect on disciplinary behavior, disciplinary behavior has an effect on performance, communication has an effect on performance, and disciplined behavior is able to mediate compensation on performance.

As a result of the COVID-19 Pandemic Outbreak, proper living for slum dwellers has become increasingly difficult, the income level of the population has decreased so that areas where slum areas were not identified at first may increase the spread of their territory. According to the Decree of the Regent of Sambas Number 872 / BAPPEDA of 2014 concerning the Determination of the Location of Housing and Slum Settlements in Sambas Regency, the slum settlement area covering an area of ​​75.77 ha is spread over 3 sub-districts covering 4 villages. Namely Pendawan Village, Tanjung Bugis Village in Sambas District, Penjajab Village, Penjajab District and Sekura Village, Sekura District. Of the 4 villages that occupy the largest area for slum areas is Tanjung Bugis Village with an area of ​​23.05 ha (30.42%). This study aims to identify the factors that cause slum areas in Sambas Regency, identify facilities and infrastructure, especially environmental roads, garbage, wastewater and housing, analyze the needs for facilities and infrastructure from the data obtained in the form of roads, to, clean water and housing. This research was conducted deductively, so that the researchers departed from theory to go into the field in conducting data searches which were then expected to analyze the facilities and infrastructure needs of the slum area in Sambas City. .From the results of this study, it is found that the factors that cause slum are insufficient income of Rp. 500,000 - Rp. 1,000,000.00, the last education is very low elementary school (elementary school) and the number of families between 3-5 people. Meanwhile, from the analysis of the need for facilities and infrastructure, appropriate technology is needed for community water sources that still use public taps, environmental roads use concrete rebates but many are still damaged, drainage channels are not there if the water is not smooth or jammed while the trash can is not owned, especially TPS (Temporary Disposal Site) for garbage.
