Abstract

EVALUATION OF COMMUNITY VULNERABILITY AND PREPAREDNESS IN FACING LANDSLIDE DISASTERS IN BERUK VILLAGE IN 2024 This study analyzes the vulnerability and preparedness of the community in Beruk Village in facing landslide disasters. Due to its hilly topography, the village is at risk of landslides every year, making it essential to enhance community preparedness to reduce disaster impacts and strengthen their resilience in emergency situations. This research adopts a quantitative approach using documentation and questionnaires involving 95 respondents from various hamlets. The data was analyzed spatially and descriptively, focusing on physical, social, economic, and environmental vulnerabilities. Preparedness was measured through indicators such as knowledge, policies, emergency response plans, early warning systems, and resource mobilization. The findings reveal that Pingkok Hamlet has a medium level of vulnerability, while other hamlets like Ngantirejo, Beruk Wetan, Beruk Kulon, and Kambangan have low vulnerability. In terms of preparedness, Ngantirejo, Kambangan, and Gunung Lading Hamlets are deemed relatively prepared, while Pingkok and Beruk Wetan fall under the category of "almost ready." Other hamlets, such as Beruk Kulon and Pringombo, are considered less prepared, and Selangkah Hamlet has shown no significant preparedness for disasters. Efforts to improve preparedness include disaster education, strengthening early warning systems, developing clear evacuation plans, and fostering greater collaboration between the government and the community. These efforts are expected to enhance the preparedness of Beruk Village against landslide disasters.

Abstract

Sawur River is a river that is the border of Central Java and East Java which has a brown to black color with a bit turbid so that it is polluted. This study aims to 1) identify the water pollution index in the Sawur River, Sambungmacan District, 2) examine efforts to control water pollution in the Sawur River, Sambungmacan District. Data analysis techniques using the pollution index method to determine the status of river pollution and SWOT analysis to formulate water pollution control efforts. Water samples were tested at 8 sample points and laboratory tests were carried out on nitrates, nitrites, ammonia, phosphates, potassium, detergent, and coliform. The results of the water quality laboratory show that there are several parameter elements that exceed the quality standards, namely nitrite, ammonia, and phosphate. The laboratory results are calculated by the pollution index formula, the pollution index is obtained at all points of the sample categorized as light pollution. According to the SWOT analysis, water pollution control efforts are in quadrant IV with a survival strategy. Efforts that can be made to control water quality over pollution are a) improve the provision of complete information, b) improve coordination between agencies on water pollution, c) increase inventory and identification of polluting sources, d) increase supervision of waste disposal, and e) increase public knowledge and participation for water quality control over pollution.

Abstract

Urbanisasi yang masif di Kota Surakarta telah mendorong peningkatan area terbangun dan alih fungsi lahan di Daerah Aliran Sungai (DAS) Kali Boro, memicu eskalasi masalah genangan akibat sistem drainase eksisting yang inadekuat. Meskipun banyak studi drainase perkotaan modern mengadopsi model numerik canggih dan solusi berbasis alam, studi ini secara strategis memilih pendekatan hidrologi-hidraulika klasik (Log Pearson Tipe III, Mononobe, Rasional, Manning) untuk mengatasi keterbatasan data spesifik dan sumber daya di tingkat mikro perkotaan tropis, sekaligus menawarkan solusi yang relevan dan aplikatif bagi Pemerintah Kota Surakarta. Pendekatan ini mengisi kekosongan literatur terkait implementasi master plan drainase mikro komprehensif di kota tropis yang masih mengandalkan data primer dan metode yang terjangkau. Penelitian ini bertujuan untuk menganalisis kondisi drainase mikro eksisting, menghitung debit banjir rencana (T = 2, 5, 10 tahun), mengidentifikasi akar permasalahan, dan menyusun master plan drainase mikro di DAS Kali Boro. Hasil analisis menunjukkan bahwa kapasitas saluran drainase eksisting hanya mampu menampung sekitar 72,5% dari debit banjir rencana untuk kala ulang 5 tahun, diperparah oleh penyempitan, sedimentasi, dan penumpukan sampah. Implementasi master plan yang diusulkan, meliputi normalisasi, peningkatan dimensi saluran, perbaikan gorong-gorong, pengelolaan sedimen dan sampah, pembangunan sumur resapan, serta adopsi drainase berwawasan lingkungan, diproyeksikan mampu mengurangi luasan genangan hingga lebih dari 50% di area prioritas. Studi ini menegaskan relevansi pendekatan konvensional yang terjustifikasi dalam konteks lokal, memberikan kontribusi signifikan dalam perencanaan ketahanan banjir di DAS mikro perkotaan tropis, dan dapat menjadi acuan kebijakan adaptasi iklim Kota Surakarta.
