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.

Abstract

Assessing the surface water vulnerability to pollution in the Garang Downstream Watershed Semarang requires a study concerned with some environmental components/indicators. Vulnerability measurement through surface water susceptibility index formulation on pollution is important considering the absence of surface water pollution effect indicators in an efficient assessment system. Therefore, a multi-indicator vulnerability assessment on surface water pollution is necessary. The Surface Water Vulnerability Index to Pollution (SWVIP) is composed of five components, namely water quality (WQ), rainfall (R), land use and vegetation cover (LVC), river hydrogeometric (RH) and population (P). Regarding index development, the subindex graphs and the weighting of each component are created. The application of composite index measurement yields an equation of SWVIP = 0.29.WQI + 0.23PI + 0.14RI + 0.20.LVCI + 0.14.RHI and an index value of 73.87 including the "rather high" category that represents the "vulnerable"condition in the Garang Downstream Watershed Semarang. This suggests that the five selected components used in the index creation can provide useful information to decision making in the surface water pollution control.

Abstract

Subdistrict office buildings, as public service infrastructure, play an important role in supporting government functions at the regional level. However, many office buildings are physically damaged or do not meet administrative requirements. This study aims to evaluate the suitability of district office buildings in Tegal Regency based on technical and administrative aspects in accordance with Ministry of Public Works and Housing Regulation No. 29/PRT/M/2006 and Law No. 28 of 2002 on Building Structures. The study was conducted on seven district offices: Bumijawa, Balapulang, Lebaksiu, Pagerbarang, Adiwerna, Talang, and Kramat. The methods used included a visual survey of structural, architectural, and utility elements with a weighting system (structure 40%, architecture 35%, utilities 25%) as well as an examination of administrative documents such as Land Certificates, KIB, IMB, and SLF. The research results showed that Talang Subdistrict had an average score of 1.41 and was categorized as Suitable. Bumijawa District (1.94), Balapulang District (1.98), and Lebaksiu District (2.01) are classified as Conditionally Feasible. Meanwhile, Pagerbarang District (2.74), Adiwerna District (2.63), and Kramat District (2.77) are categorized as Not Feasible. From an administrative perspective, none of the subdistricts have building permits (IMB) or site clearance certificates (SLF), resulting in an average administrative score of only 2 out of 4 points (50%). This study recommends gradual improvements, prioritizing technical rehabilitation budgets, and expediting the processing of legal documents to enhance the suitability of subdistrict office buildings
