Abstract

The competition strictness in the economic field needed the exact strategy to maximising the available potential. As the  island area that was surrounded by ocean, the Mukomuko Regency in Bengkulu, had the big potential to be developed especially in the export import activity and the sea transportation. There were 4 port kinds that will be developed in the Mukomuko Regency those  are the crossing port, the sea port, the trade port and the fish port. The determination of priority in the port kind and it location that developed immediately must be carried out, so  the port that was built could be used maximally. The data collection was carried out with observation and the interview. The variables that was used as the determination criterion of  priority in the port development was marine aspect,  fisheries aspect,  transport aspect, layout aspect and environment aspect. The research results showed that location in Mukomuko more appropriate for the crossing port, the location in Bantal was more appropriate for the fish port, the location in the Kumbang Badak appropriate for the sea port and the location in the Kuala Tramang more appropriate for the trade port especially agricultural produce. Based on result of Analytical Hierarchy Process (AHP),  the development of  sea port in  Kumbang Badak became the main priority to built immediately. Keywords:  priority, port development, AHP   ABSTRAKKetatnya persaingan di bidang perekonomian memerlukan strategi yang tepat dalam  mengoptimalkan potensi yang ada.  Sebagai daerah kepulauan yang dikelilingi lautan, Kabupaten Mukomuko di Bengkulu,  memiliki potensi untuk dikembangkan terutama dalam kegiatan ekspor impor dan transportasi laut.

Abstract

The Kaligawe Genuk area is the main route for the North Coast (Pantura) of Java.The area is the gateway to the city of Semarang from the east direction. Since 2005,this area has frequently had floods caused by tides (tidal floods) and rainfall. TheCentral Government, supported by the Semarang City Government, built the KaliTenggang and Sringin Polder systems from 2016 to 2019. In terms of capacity, thissystem is not yet perfect for dealing with floods, and it requires efforts so that thesystem can be operated optimally. This study activity aims to simulate rainfall flowrate, the pump capacity, and the retention pond. The simulation results will becomethe basis for the development of the polder system operational manual. Theimplementation method collects secondary rainfall data, reviewing the condition ofa catchment area, retention pond, and pump station. Focus group discussion withstakeholders done in the Kaligawe Genuk area. The location of the activity is morefocused on the Kali Sringin area. This study produces tables and graphs of pumpcapacity simulation, retention ponds, and an operational manual for the SringinPolder system. It is hoped that this guideline will become the basis for the poldersystem's sustainable operations.

Abstract

Semarang as a city located in the coastal area is dealing with the some problems, such as rising sea level, land subsidence, scarcity of land and illegal settlers. In order to deal with rising sea level, a polder system is developed in Kemijen (northern of Semarang). This polder system depends on dredging, a pumping station and retention basins to store water. To make the polder function well and reduce the floods, the existing retention basins should be expanded. Therefore, people who are living at the borders of these basins should be relocated or floating houses could be a solution.. This study aims to determine the acceptance of the Kemijen inhabitants towards floating houses as alternative residential in coastal areas. Data collecting in this study were obtained through interviews with the Kemijen residents and stakeholders. The data  then processed by SWOT analysis. Based on the research result, it can be concluded that the social acceptance of the inhabitants is quite low, but there is potential because they see positive elements in a floating house. According to the survey most inhabitants do have insufficient income to pay for a floating house. Building on water is still not legal in Indonesia and therefore the law should probably be adjusted. Besides the land owner is still reluctant in building legal houses on its land. In order to improve the social acceptance of floating houses, these factors should be strengthening, namely relative advantages, compatibility, complexity, trialability and observability.

Abstract

Tambak Lorok in Semarang is one of the areas that often undergoes tidal floods. The construction of dam and dike infrastructure is an effort to overcome tidal floods. As one part of the flood control system, the dike has an important role. The construction projects requires an alternative selection method of dike construction in order to function optimally. This research aims to determine the order of priority criteria and alternative construction of dikes. The data were obtained through questionnaires to experts in the field of dike construction. The aspects of criteria used to analyze alternative dike construction are : functions and benefits, site conditions, costs and construction implementation.  The dike construction alternatives include a Concrete Sheet Pile (CSP), Parapet Wall with reinforced Corrugated Concrete Sheet Pile/CCSP and landfill with Geotube Components. The questionnaire were processed using the Analytical Hierarchy Process (AHP) method with the Expert Choice v.11 application. The results showed consistency ratio (CR) of 5%, which means that research data were consistent and could be accounted for. Based on weighting in pairwise comparisons, the priority criteria in selecting type of dike construction are : functions and benefits (33%), site conditions (32%), cost (18%) and construction implementation (17%) The priority alternative dike construction is reinforced Corrugated Concrete Sheet Pile/CCSP (39.7%), landfill with geotube components (3.28%) and Cylindrical Concrete Piles (CSP) (27.5%). Dike construction with reinforced CCSP is a top priority in the handling of tidal floods in the Tambak Lorok.

Abstract

Kaligawe merupakan salah satu daerah rawan banjir di Kota Semarang. Kawasan Kaligawe termasuk dalam Sub Sistem Kali Tenggang. Penanganan terhadap banjir di Kaligawe telah dilakukan oleh pemerintah berupa normalisasi sungai dan pembangunan sistem polder sebagai bagian dari sistem drainase. Untuk menjamin keberlanjutan pengelolaan sistem drainase, diperlukan keterlibatan seluruh stakeholders, termasuk partisipasi masyarakat yang bertempat tinggal di dalamnya. Di wilayah Kaligawe, ada beberapa bangunan infrastruktur pengendali banjir seperti kolam retensi, rumah pompa, pintu gerak dan saluran drainase. Bangunan infrastruktur tersebut dapat terganggu fungsinya bila masyarakat tidak peduli, seperti membuang sampah di saluran drainase, merusak kolam retensi, mengambil/mencuri peralatan di rumah pompa dan lain sebagainya. Oleh sebab itu warga di kawasan tersebut perlu mendapatkan edukasi bagaimana hidup di lingkungan sistem polder. Sekolah Dqsar (SD) Kaligawe berada di wilayah Kaligawe, dimana para guru perlu diberikan edukasi agar dapat ikut berpartisipasi dalam pemeliharaan bangunan infrastruktur pengendali banjir. Edukasi yang akan diberikan meliputi pemahaman tentang penyebab dan dampak banjir di Semarang, penanganan banjir dan bangunan infrastruktur pengendali banjir di sekitar sekolah serta mitigasi bencana dan konsep Sekolah Siaga Bencana (SSB). Hasil pre-test terhadap guru, menunjukkan bahwa guru-guru di SD Kaligawe masih banyak yang tidak memahami bangunan pengendali banjir yang ada di sekitar lingkungan kerja mereka. Melalui edukasi yang diberikan dalam penyuluhan, guru-guru bisa memahami peran yang harus dilakukan dalam menjaga keberlangsungan bangunan pengendali banjir. Hasil post-test menunjukkan tingkat pemahaman yang meningkat pada guru-guru terhadap pengendalian banjir di wilayah Kaligawe.Kaligawe is one of the flood areas in the city of Semarang. Kaligawe area is included in the Kali Tenggang Sub-System. The government has handled floods in the area in the form of river normalization and construction of a polder system as part of the drainage system. To ensure the sustainability of the drainage system management, it requires the involvement of all stakeholders, including the participation of the people who live in it. In the Kaligawe area, there are several flood control infrastructure buildings such as retention ponds, pump houses, mobile gates and drainage channels. The function of these infrastructure buildings can be disrupted if the community does not care, such as throwing garbage in the drainage channels, damaging retention ponds, taking / stealing equipment at pump houses and so on. Therefore, residents in the area need to get education on how to live in a polder system environment. SD Kaligawe is located in Kaligawe area, where teachers need education in order to participate in the maintenance of flood control infrastructure. The education that will be provided includes understanding the causes and impacts of floods in Semarang, flood management and building flood control infrastructure as well as disaster mitigation and the concept of Disaster Alert School (SSB). The results of the pre-test conducted in this study showed that many teachers at SD Kaligawe did not understand the flood control buildings that were around their school environment. Through the education provided in counseling, teachers can understand the role that must be played in maintaining the sustainability of flood control buildings. The results of the post test showed an increased level of teachers on understanding of flood control in the Kaligawe area.
