The Geospatial and Mining Geology Expertise Program at SMKN 1 Balikpapan has limitations in terms of facilities and infrastructure, the workshop building uses a former automotive workshop building which is not sufficiently representative as other skill program workshops. In terms of Geomatics practice equipment, two skill programs with resource sharing with very minimal facilities, where the equipment owned are as follows: 3 units of PPD, 1 unit of Digital Theodholite, and 2 units of TS where 1 battery unit is damaged, not proportional to the number of students with geospatial skills as many as 165 people with 6 teachers and 248 skill students with 8 teachers being less than optimal during geomatics practice. The assistance and training of the simulation tool survey and stake out guide carried out by the PkM Poltekba team is an alternative tool for the teaching and learning process in the field of measurement, making it easier for teachers and students to facilitate basic measurements and surveys in the field and reduce the risk of using limited tools so that the teaching and learning process becomes more optimal.

Beton non pasir merupakan jenis beton dengan porositas tinggi sehingga dapat dimanfaatkan untuk mempercepat penyerapan air hujan kedalam tanah. Penelitian ini terdapat dua uji, yakni uji infiltrasi dan kuat tekan beton tanpa pasir. Penelitian menggunakan 48 sampel untuk uji kuat tekan dan 16 sampel untuk uji infiltrasi dengan penambahan Sikamen-NN menggunakan variasi 0,8%, 1%, 1,2% serta 0,6% serat polipropilen terhadap berat semen. Agregat kasar menggunakan ukuran diameter lolos saringan ¾ tertahan pada saringan ½ 100% dan agregat kasar dengan  ukuran diameter lolos saringan ½ tertahan saringan 100% yang berasal dari daerah Palu. Kemampuan terbesar infiltrasi beton non pasir adalah 41,80 mm/detik dan kuat tekan terbesar adalah 11,70 MPa  dengan menggunakan agregat kasar ukuran diameter lolos saringan ½ tertahan saringan 100% ditambahkan dengan variasi Sikamen-NN 1,2%.

The industrial Revolution 4.0 is the integration of cyber technology, and automation, to enhance the effectiveness and efficiency. Therefore, accessibility to the information can be done at any-time and anywhere through the availability of internet networks. The Integrated Islamic School Ibnu Hajar is the institution that manages early childhood education school, elementary school and junior high school. It needs information systems in managing employee and student presence record. The systems development processes are consisted of pre-development, system analysis, system design, system development, system training and testing, and system implementation. The results are multimedia based on information system and the application of presence (http://sim.ibnuhajarbpn.sch.id). The employee presence system using android and web app which can be done by displaying QR and scanning QR in e-billboard or displaying QR on the laser scanner.

Occupational health and safety is one important aspect in a company so that the company can minimize a work accident, where in case of a work accident then it can hamper the productivity of employees. The purpose of this study is to determine the application of occupational safety and health on the productivity of employees and how the influence of which is given of the application. This research method using quantitative analysis with the data analysis technique used is the analysis of descriptive statistics. In the analysis descriptive statistics variable values obtained for the variable health & Safety is equal to 3.62 which means very high then on the productivity variable that is equal 3,47 that is very high. It can be concluded that has been conducted on the application of occupational safety and health thereby increasing employee productivity.
