Tujuan penelitian ini adalah: (1) identifikasi lokasi point of inception pemasukan udara alamiah (self air entrainment) pada saluran curam di lokasi developing aerated flow; (2) deskripsi distribusi konsentrasi gelembung udara pada kondisi pemasukan udara alamiah (self air entrainment) di lokasi developing aerated flow. Dua tujuan penelitian dicapai menggunakan metode eksperimen yang dilaksanakan di Laboratorium Hidraulika Jurusan Teknik Sipil dan Lingkungan (JTSL) Fakultas Teknik UGM. Pada penelitian ini digunakan saluran curam yang mempunyai panjang 10 m, lebar 0,2 m, tinggi 0,4 m dengan kemiringan berubah-ubah mulai 15Âº, 20Âº, dan 25Âº, yang menyatu dengan dinding bak air. Debit divariasikan mulai dari 9,4 l/s, 11,5 l/s dan 20,9 l/s. Distribusi konsentrasi gelembung udara hasil eksperimen dibandingkan dengan hasil perhitungan menggunakan persamaan Chanson (1995) serta Straub dan Anderson (1958). Hasil penelitian ini adalah (1) letak point of inception eksperimen untuk Î±=15Â° adalah 4,4 m dari inlet flume; untuk Î±=20Â° adalah 4 m dari inlet flume; dan untuk Î±=25Â° adalah 3,4 m dari inlet flume; (2) profil distribusi konsentrasi gelembung udara di titik 6,2 m di hilir inlet flume dapat dikategorikan sebagai partially aerated flow; dan(3) profil distribusi konsentrasi gelembung udara di titik 7,2 m di hilir inlet flume dapat dikategorikan sebagai fully aerated flow.

Program PAMSIMAS merupakan salah satu program pemerintah yang mendukung program nasional dalam mencapai target 100% akses air minum dan sanitasi. Program PAMSIMAS juga memfasilitasi dan mempromosikan sanitasi yang layak, perilaku hidup bersih dan sehat. Penelitian ini bertujuan memberikan gambaran mengenai pelaksanaan program PAMSIMAS di Desa Lam Reh, Desa Lambaro Sukon, dan Desa Lambaro Biluy di Kabupaten Aceh Besar. Selain itu, penelitian ini juga mengidentifikasi faktor-faktor keberlanjutan program serta menilai keberhasilan Program PAMSIMAS di masing-masing desa agar fasilitas yang dibangun program PAMSIMAS dapat digunakan sebaik-baiknya. Penelitian ini menggunakan pendekatan kuantitatif dengan menggunakan metode induktif. Data yang digunakan data sekunder dan data primer yang didukung dengan wawancara terhadap pelaku terkait program PAMSIMAS tingkat kabupaten maupun desa. Analisis yang digunakan yaitu analisis deskriptif kualitatif. Adapun hasil dari penelitian ini menunjukkan bahwa keberhasilan dari Desa Lam Reh dan Desa Lambaro Sukon sudah dalam kategori Amat Baik, beberapa variabel seperti sumber air, PHBS, pengelolaan masyarakat, dan keberfungsian sarana sudah lebih dari 50%. Namun, untuk Desa Lambaro Biluy, pengelolaan masyarakat dan keberfungsian sarana masing-masing sebesar 44,4% dan 0%, sarana air minum yang dibangun oleh program PAMSIMAS tidak lagi difungsikan.

Duri Field covers an area of approximately 9500 hectars that will be developed with steam injection (steamflooding) into I3 areas. During rainy season, several part of the Duri Field are inundated by rain water that disturbing the operation of the exploration. The problent of inundation in The Duri Field Area that endanger the CPI focilities could be caused by limited canal capacity and bad performance of hydraulic stuctures, change of Rainfall – Runoff relation due to the change of infiltration capacity of the watershed area, land subsidence due to excess load and ground water extraction. Unfurtunately, part of the Duri Field is laid down on the peat soil dome that is subject to land subsidence under an intensive drainage.The important issues in developing a peat lands are land subsidence due to shrinkage and changes to peat properties. Oxidative changes are irreversible. The effort of draining the excess run-off water by increasing the existing canal capacity shall in no way cause for over-draining and lowering the gyound water level during dry season. The drainage system shall be designed to maintain this ground water level to avoid any soil subsidence and drying the peat. An hydraulic simulation to analyze the probable ground waler extraction is performed.The result of conventional hydraulic simulations require a widening and deepening part of the primary canal. This channel improvement will increase the drainability, but in the other side could prontote the lowering of water table, peat oxidation and land subsidence. Instead of channel improvement, increasing the elevation of Duri Field facilities above flood level and developing collector drainage channel along the border of Duri Field are suggested. Keywords: drainage, peat soil, subsidence.

The PAMSIMAS program is one of the government programs supporting the national program to achieve 100% access to drinking water and sanitation. The PAMSIMAS program also facilitates and cleans proper sanitation, living, and healthy behavior. This study aims to provide an overview of the PAMSIMAS program's implementation in Lam Reh Village, Lambaro Sukon Village, and Lambaro Biluy Village in Aceh Besar District. The research also identifies factors of program sustainability and assesses the PAMSIMAS program in each village so that the facilities built by the PAMSIMAS program can be used properly.This study uses a quantitative approach using inductive methods. The data used are secondary data and primary data supported by interviews with actors related to the district and village PAMSIMAS program. The analysis used is descriptive qualitative analysis. This study's results indicate that Lam Reh and Lambaro Sukon Villages' belief is already in the Very Good category. Several variables, such as water sources, PHBS, community management, and facilities functioning, are more than 50%. However, for Lambaro Biluy Village, community management and functioning of the facilities were 44.4% and 0%, respectively, the drinking water facilities built by the PAMSIMAS program are no longer functioning.

The history of the water resources development in the world is generally inspired by the physical, climate and socioenvironment conditions such as geographical, culture and civilization at the local level. For many years, humans have spent tremendous efforts and time improving the quality of life through adequate water utilization. This research, therefore, aims to analyze the ancient water-related infrastructures as cultural heritages in creating a functional and adequate design. Data were obtained from the Mataram Canal in Yogyakarta Province which was selected due to the success story and various benefits associated with the Indonesian history of water resources in Central Java provinces. Today, some places along the canal have become tourist destinations, and it is more popular in Yogyakarta due to its architectural history. However, the diversification of water utilization in fishery ponds along the canal and the shift in land utilization from rice field to housings, and government buildings may undermine the function of the canal. The factual condition associated with the periodic decrease in irrigation command does not make the Mataram Canal useless. Therefore, efforts to maintain its function through restoration, and revitalization, can enhance water supply for irrigation and other purposes such as fish ponds and, pollutant dilution. The Strength-Weakness-Opportunity-Threat (SWOT) method with some key performance indicators was adopted to access the necessity of the sustainability program of the Mataram Canal as the heritage infrastructure. Some key performance indicators related to Integrated Water Resources Management (IWRM) program in Indonesia were introduced and utilized to prioritize the necessary actions. The results showed that the SWOT analysis promotes various actions to support the IWRM-related program of Mataram Canal. Furthermore, the implementation of the promoted actions would contribute to the longer sustainability of the Mataram Canal.
