“…Bencana alam yang terjadi saat ini lebih kepada adanya suatu fenomena degradasi lingkungan dan berdampak pada terjadinya perubahan iklim global. Akibat perubahan iklim global menyebabkan meningkatnya elevasi permukaan air laut, berkurangnya jumlah hari hujan dan meningkatnya intensitas hujan (Suripin & Kurniani, 2016). Fenomena degradasi lingkungan ini perlu diimbangi dengan adanya perubahan dan penyesuaian dalam pengelolaan sumber daya air serta perencanaan pembangunan berkelanjutan.…”

Fenomena degradasi lingkungan menyebabkan meningkatnya frekuensi banjir di beberapa wilayah, salah satunya adalah kawasan pesisir pantai Kota Semarang. Kecamatan Genuk, Kecamatan Tugu, Kecamatan Semarang Utara, dan Kecamatan Semarang Barat merupakan empat wilayah yang berbatasan langsung dengan Laut Jawa. Kondisi topografi dan karakteristik wilayah empat kecamatan tersebut menyebabkan empat kecamatan tersebut rawan mengalami bencana banjir. Untuk mengatasi fenomena tersebut perlu adanya penyesuaian perencanaan pembangunan berkelanjutan. Agar perencanaan tersebut efektif maka diperlukan analisa untuk menentukan faktor utama penyebab permasalahan banjir di wilayah tersebut. Oleh karena itu, dalam penelitian ini dilakukan analisa tingkat risiko banjir menggunakan metode AHP TOPSIS untuk menentukan faktor utama penyebab banjir di masing-masing kecamatan. Kriteria yang digunakan dalam analisa terdiri dari curah hujan, tata guna lahan, kemiringan lahan, dan ketinggian. Berdasarkan hasil analisa, didapatkan bahwa Kecamatan Semarang Utara dan Semarang Barat memiliki tingkat risiko paling tinggi terhadap bencana banjir. Faktor dominan penyebab tingginya risiko banjir di dua kecamatan tersebut dibanding dua kecamatan lainnya adalah curah hujan. Sedangkan faktor utama penyebab banjir di kawasan pesisir pantai Kota Semarang adalah ketinggian

Climate change has brought changes to the characteristics of the rain, wherein the rainy season duration is short; however, the dry season is getting longer. This study aims to detect the climate change presence or absence, identify the relationship of climate change to the nature of rainfall, and the relationship of climate change to rainy, humid and dry months. This research was conducted in the Mepanga Watershed, Parigi Moutong Regency, Central Sulawesi, Indonesia. The Makesens method is used for climate change detection. The rainfall characteristics use standard deviation statistical methods; furthermore, the Oldman method is used for dry, humid, and wet months. The data used is rainfall data for 30 years (1990-2019) from Kayu Agung Station. The results show that there has been a climate change in the Mepanga watershed. Marked by a Z ≠ zero value, where there is a positive trend (Z> 0) and a negative trend (Z <0). The increase in rainfall and conversely indicates the positive trend; otherwise, a decrease in rainfall indicates a negative trend. There is an effect of climate change on the nature of rain, wet, humid and dry months but not significant.

“…The climate issue has resulted in changes in the duration of the season, where the rainy season is getting shorter while the dry season is getting longer. As a result, the intensity of rain increases while the number of rainy days decreases, thereby increasing the risk of flooding [1]. Furthermore, asphalt and concrete layers that have impermeable properties are being used in the construction of residential roads, parking lots, and parks.…”

In Indonesia, paving blocks are one of the most extensively used building materials. Paving blocks are ideal for making roads, parks, and parking lots because they are easy to install, durable, and weather-resistant. The high demand for paving blocks contributes to the increasing demand for aggregate as the main material for paving blocks. This has an indirect impact on the environment. On the other hand, building demolition waste is increasing. The majority of these building materials are non-biodegradable, such as concrete, plaster, brick walls, and tiles, which could harm the environment. Therefore, this study aims to see the possibility of using demolished concrete, brick walls, and tiles as a substitute for the aggregate in the production of permeable paving blocks. Each substitute material is then sampled and evaluated with compressive strength and infiltration rate to find the most optimum permeable paving block design. Based on the analysis, permeable paving blocks that use concrete as a substitute for coarse aggregate have better permeability and compressive strength compared to paving blocks that use brick walls and tiles waste. This paving block has an infiltration rate of 858 mm/hour and compressive strength of 11.68 MPa which is suitable for use in the park.
