Abstract

Karakteristk hidrodinamik, dan pola aliran pada aliran berlawanan arah udara-air dalam pipa vertikal telah dilakukan. Pengukuran ketebalan film dengan metode konduktimetri, dan penurunan tekanan dengan manometer U. Untuk mendapatkan aliran berlawanan arahm udara-air, maka air dialirkan dari atas melalui media berpori, sedangkan udara diinjeksikan dari bawah secara aksial. Pengukuran ketebalan film dilakukan pada jarak (X) 400, 1600, dan 2400xmm dengan variasi angka Reynolds air (ReL) 845-2446 dan laju injeksi udara dengan kecepatan 1.84-5.54m/s dari injektor air. Pengukuran ketebalan film dilakukan secara simultan. Hasil perhitungan menunjukkan bahwa kurva ketebalan film terjadi penurunan secara perlahan-lahan dengan meningkatnya laju aliran udara. Tetapi, saat flooding besaran ini turun drastis, dan gradien tekanan (dp/dx) tiba-tiba meningkat tajam. Flooding diawali ketidakstabilan aliran film dimulai dari sisi bagian bawah saluran, kemudian membentuk formasi gelombang-gelombang kecil dan pola aliran acak bergerak ke atas secara simultan. Saat flooding pola aliran ini berubah menjadi pola aliran annular mengalir ke bawah. Pada transisi aliran, dimana struktur aliran lokal turun drastis dan kemudian konstan sebagai fungsi waktu. Pengukuran ketebalan film dari tiga titik menunjukkan bahwa flooding terjadi lebih awal pada sisi bagian atas dekat sisi masuk air.

Abstract

The village is the foremost and closest government agent and is able to directly touch the interests of the community. One of its efforts is through the establishment of Village-Owned Enterprises (BUMDes), which in Aceh are called the Village-Owned Enterprises (BUMG). In its management, BUMG has several management principles, one of which is participation. Therefore, women also have the right to participate in the management of BUMG. Blang Krueng Village is one of the villages that has the best BUMG in Aceh and the 2016 National level of participation category. This study aims to look at the participation of women in the management of BUMG in Blang Krueng Village and the factors that influence women's participation in the management of BUMG in Blang Krueng Village. In this study, researchers used descriptive qualitative research. Based on the results of the study, it was found that the management of BUMG Blang Krueng Village has involved women in the planning process, delivery of aspirations, implementation and evaluation. In organizing, women are also involved as managers. It can be seen from 11 (eleven) business units that have been established, there are 5 (five) Blang Krueng BUMG business units which are chaired by women
