Abstract

Tingkat keselamatan di jalan tol khususnya dalam kota perlu diperhatikan digunakan masyarakat untuk kegiatan sehari-hari. Potensi bahaya dan permasalahan di Jalan Tol Ir. Wiyoto Wiyono MSc perlu diidentifkasi untuk menemukan penanganan yang efektif. Fokus terhadap keselamatan di jalan tol menjadi penting mengingat jalan tol memungkinkan kendaraan melaju dengan kecepatan tinggi, kemudian kendaraan berat dan kendaraan pribadi yang menjadi satu pada ruas jalan. Alasan-alasan tersebut sudah dapan menjadi penyebab kecelakaan terjadi di jalan tol. Oleh karena itu keselamaran di jalan tol perlu memperoleh perhatian khusus oleh pengelola Jalan Tol Ir Wiyoto Wiyono MSc. Metode deskriptif kualitatif digunakan untuk menginterpretasikan temuan yang ada secara mendalam. Observasi langsung dilakukan secara aktif dalam studi kasus yang diamati. Hal ini dilakukan untuk mempermudah mengetahui kondisi eksisting secara akurat. Penelitian ini mengidentifikasi 5 potensi bahaya dan permasalahan yang mungkin terjadi di lokasi studi di masa mendatang. Hasil yang diperoleh adalah railling terputus hampir merata di setiap tiang APJ (Alat Penerangan Jalan) jalur NSL (North South Link), bahu jalan  sempit, kerusakan jalan akibat kendaraan ODOL (Over Dimension Over Loading), kemacetan di hampir seluruh ruas pada jam puncak dan adanya kolong tol. Rekomendasi penanganan yang ditawarkan berupa penggantian median railling menjadi barrier, patroli dan derek yang cepat tanggap, operasi ODOL rutin, serta sidak rutin penertiban kolong tol.

Abstract

The study namely Drought Analysis Using Various Drought Indices in District Ngemplak, Boyolali offers a comprehensive examination of drought phenomena in the Ngemplak, Boyolali district through the lens of var­ious drought indices, aiming to understand the impact on agricultural productivity and propose effective water management strategies. Using data from 2009 to 2023, this study used SPI and PDSI.  Focusing on the Ngem­plak, Boyolali district, this research identifies the most relevant drought indices tailored to the local climatic and geographical contexts, analyzes the correlation between these indices and the productivity of primary crops, and suggests sustainable water management practices to mitigate drought risks. The study underscores the importance of adopting a multifaceted and adaptive water management framework, incorporating sophisticated irrigation technologies, and fostering policy reforms to enhance water use efficiency and resilience against climatic variability. It calls for collaborative efforts involving stakeholders across different sectors to implement these recommendations, ensuring the sustainability of water resources and agricultural productivity in the face of drought challenges.

Abstract

Concrete is a widely used construction material, but its production has a negative impact on the environment. This study aims to determine the effect and optimal percentage of using palm kernel shells and coconut fiber in concrete mixtures on the compressive strength of concrete. The research method involved making a variety of concrete mixes with the replacement of conventional aggregates by palm kernel shells as coarse aggregate and coconut fiber as fine aggregate. Four mix variations were tested: A (1% coconut fiber, 5% palm kernel shell), B (2% coconut fiber, 5% palm kernel shell), C (1% coconut fiber, 10% palm kernel shell), and D (2% coconut fiber, 10% palm kernel shell). Compressive strength testing was conducted at 7, 14, and 28 days of concrete age. The analysis showed that variation A, with 1% coir and 5% palm kernel shell, produced the closest compressive strength to normal concrete. ANOVA tests confirmed the significant effect of these mixtures on compressive strength. The contribution of this research lies in the development of alternative concrete materials that are more environmentally friendly, utilizing agricultural waste to reduce dependence on natural resources and lower the carbon footprint of the construction industry.

Abstract

This study investigates the impact of the Southern Oscillation Index (SOI) on meteorological droughts in the Bengawan Solo River Basin, Indonesia, from 2004 to 2023. Indonesia’s climate is influenced by the El Niño Southern Oscillation (ENSO), with negative SOI values (El Niño conditions) linked to drought events and positive values associated with the rainy season. This study analyzed the values of multiple stations' Rainfall Anomaly Index (RAI) and Standardized Precipitation Index (SPI).  This study evaluates the compatibility of drought indices obtained from the Rainfall Anomaly Index (RAI) and the Standardized Precipitation Index (SPI) with the Southern Oscillation Index (SOI). The study's results indicate that the drought index using the Standardized Precipitation Index (SPI) method yields a higher percentage of compatibility with the Southern Oscillation Index (SOI), averaging 60.78%.  The compatibility of the SPI method can also be observed in the number of meteorological dry months during 2010, the year of the most severe La Niña, and in 2015, during the most severe El Niño.  Through the SPI method, it can also be demonstrated that rainfall data can accurately reflect drought events and rainy seasons, consistent with climate change occurrences.

Abstract

Daerah Aliran Sungai (DAS) Padolo mempunyai luas 222,89 km2. DAS Padolo bagian hulu berada di Kabupaten Bima, sedangkan bagian hilir berada di Kota Bima. Selain memberikan banyak manfaat, DAS Padolo juga memberikan dampak negatif bagi masyarakat, terutama dibagian hilir yaitu terjadinya banjir. Perubahan tata guna lahan merupakan salah satu pemicu meningkatnya debit banjir. Tujuan penelitian ini untuk mengetahui pengaruh perubahan tata guna lahan terhadap debit banjir pada DAS Padolo. Dalam penelitian ini analisis intensitas hujan menggunakan metode Mononobe, analisis tata guna lahan menggunakan peta tata guna lahan dari DLHK propinsi NTB, sedangkan analisis debit banjir menggunakan software HEC-HMS versi 4.12. Parameter tata guna lahan menggunakan Curve Number (CN). Hasil analisis perubahan tata guna lahan  selama kurun waktu antara tahun 2014 s/d 2023 menunjukkan lahan pertanian lahan kering mengalami peningkatan yang sangat besar yaitu sebesar 2.318, 53%. Penggunaan lahan lain yang mengalami peningkatan adalah sawah, permukiman dan hutan lahan kering sekunder masing-masing sebesar 111,14%, 69,38% dan 49,89%.  Sedangkan penggunaan lahan yang mengalami penurunan luas adalah semak belukar sebesar 89,7%.  Pertanian lahan kering campur juga mengalami penurunan luas lahan sebesar 67,70%. Perubahan tata guna lahan tersebut menyebabkan peningkatan debit banjir rata-rata sebesar 8,91%.
