The shifting curriculum into curriculum 2013 also occurs on several productive subjects at Vocational high school in which there is one additional subject, Highway and Bridge Constructions. As this is a new subject, frankly the teacher is required to be able to understand the materials and deliver them to the students. One of proposing ways to deliver the materials is by developing electronic modules, commonly known as e-module, based on project based learning. This e-module uses Moodle (Modular Object Oriented Dynamic Learning Environment) in which the teacher is able to insert teaching materials in the form of text, animation, audio, video as well as assignments and assessments. Moreover, this research is Research and Development (R&D) with ADDIE development models, namely Analysis, Design, Development, Implementation and Evaluation. The findings showed that the validation of the product was in the good category with slight revision. Furthermore, in terms of respondents' evaluation the results unveiled that respondents felt satisfied in which the respondents' evaluation was in excellent category. Therefore, it can be concluded that e-module eases both teacher and students in teaching and learning highway and bridge construction subject.

Kegiatan komunikasi K3 merupakan bentuk sosialisasi K3 dalam rangka meningkatkan periku K3 seluruh kalangan di proyek konstruksi. Namun kenyataan dilapangan, hanya sebagian kecil partisipan yang mengikuti komunikasi K3 dengan serius. Selain itu, efektifitas kegiatan tersebut dinilai kecil karena banyak pelanggaran APD yang dilakukan baik pekerja, karyawan ataupun tamu. Penelitian ini bertujuan untuk mengetahui korelasi komunikasi K3 eksternal dengan tingkat kepatuhan APD. Penelitian ini bersifat kuantitaf dengan desain deskriptif. Pengumpulan data menggunakan kusioner yang disebarkan kepada tamu proyek dengan jumlah 15 sampel. Uji validasi instrumen dilakukan dengan expert judgment dengan 3 validator isi dan 1 validator bahasa. Analisis dilakukan dengan uji korelasi product moment. Hasil penelitian menunjukan bahwa tidak terdapat hubungan antara komunikasi K3 external dengan kepatuhan APD bahwa thitung < ttabel (0,725953115 < 2,262). Berdasarkan penelitian tersebut dapat disimpulkan bahwa, kegiatan komunikasi K3 external sudah berjalan baik (82,6%). dan tingkat kepatuhan APD berada pada kategori baik (83,49%).

The problem faced by farmers in Parambahan Region during the dry season is agricultural land does not get adequate water supply from existing irrigation channels, as a result, farmers can only carry out agricultural activities during the rainy season in Parambahan Region Lima Kaum Subdistrict, district of Tanah Datar. This study aims to determine the location and depth of soil layers containing groundwater by using the seismic method, measurements are carried out at two points, with the length of the track at the first point is 80 meters, and at the second point of 70 meters, each measurement on seismic data collection using 4 geophones as signal capture sensors, with a distance between geophones of 5 meters. The results of this study that the wave velocity at the first data point collection was 169.49 m / s and the lowest were 87.1 m / s, and the wave velocity at the second point was 129.68 m / s and the lowest was 48.07 m / s. from the wave velocity, it can be seen the type and depth of the groundwater layer at the point of data collection on the first pass, which is a depth of up to 27.5 meters of the possibility of soft soil and a depth of about 30 to 40 meters of watery soft soil at that depth may have groundwater, and at that point, the second passage at a depth of up to 25 meters is likely to be soft soil and at a depth of around 25 to 35 meters of watery soft soil at that depth, there is groundwater.
