Abstract

17 August 1945, University Surabaya has expanded its limited green space and educated students and the community about plant development without planting material, or it is referred to as contemporary farming by using the rooftop area on the third level of the Engineering Building (Q) for hydroponic plant cultivation. Using the PDCA (Plan, Do, Check, Action) method, one may improve the productivity of plants in hydroponic farming. The NFT (Nutrient Film Technique) system, which consists of three pipes stacked in parallel places, is used in the design of the hydroponic growing system. Rockwool, flannel cloth, plastic cups, nutrients, and a pH or TDS (Total Dissolved Solid) measuring device are among the equipment and supplies utilized. Choosing plants that can be used on small amounts of land are.

Abstract

Tiap tahun di sebuah program studi pasti ada mahasiswa baru yang masuk yang berasal dari berbagai wilayah. Penelitian ini bertujuan menganalisis data mahasiswa di prodi Teknik Industri Untag Surabaya berdasarkan sebaran asal SMA, program peminatan saat menempuh studi di SMA, jenis kelamin, jarak kedekatan rumah tempat tinggal dengan kampus, dan jenis pekerjaan orang tua. Data yang diperoleh akan diolah menggunakan algoritma K-Means Clustering. Data-data yang memiliki kesamaan karakteristik akan dikelompokkan menjadi satu klaster, sedangkan data dengan karakteristik yang berbeda akan dikelompokkan dalam klaster yang lainnya. Klaster yang terbentuk akan dibagi tiga yaitu tinggi, sedang dan rendah. Dari klaster yang tinggi akan dianalisis potensi terbesar yang dapat digunakan sebagai strategi marketing untuk meningkatkan jumlah mahasiswa baru di periode mendatang. Dari hasil pengolahan data menggunakan Rapidminer, diperoleh hasil cluster 0 terdiri dari 75 data, cluster 1 sebanyak 31 data, cluster 2 sebanyak 55 data. Dari hasil clustering, atribut yang membedakan cluster secara signifikan adalah jarak tempat tinggal ke kampus. Dari cluster yang tertinggi diperoleh data rata-rata jarak tempat tinggal mahasiswa ke kampus adalah 4,6 km dengan jangkauan antara 0,1 km sampai 10 km. Promosi dapat lebih ditingkatkan pada daerah-daerah dengan jangkauan jarak yang lebih jauh agar menambah perolehan jumlah mahasiswa baru.

Abstract

Slope failure can occur even though slope design and reinforcement have been carried out. However, before it completely collapses, there are often signs from the slope. These signs should be carefully observed through slope monitoring or surveillance activities to provide advance warnings regarding the development of slope instability, allowing mitigation measures to be implemented to reduce or avoid the impacts of instability, as well as to predict the timing of landslides using Inverse Velocity. This study was conducted at the PIT of PT Fajar Sakti Prima in East Kalimantan Province. Observations were carried out over 39 days to obtain deformation behavior, velocity values for mitigation actions, and inverse velocity values to predict the timing of landslides. In this observation, the deformation behavior values at PM 01, PM 02, and PM 03 were initially linear, then exhibited progressive behavior on November 7-8, 2024. The predicted landslide timing from this observation was November 20-21, 2024. Based on velocity values correlated with the TARP, critical categories were obtained at 7.40 - 9.86 cm/day and very critical at >26.17 cm/day
