Abstract

AbstrakDesa Kedamean merupakan salah satu desa yang berada di Kecamatan Kedamean, Kabupaten Gresik bagian selatan. Mayoritas penduduk Desa Kedamean bermata pencaharian sebagai petani dan buruh pabrik. Berdasarkan data Kementrian Lingkungan Hidup dan Kehutanan tahun 2020, di Kabupaten Gresik Provinsi Jawa Timur terdapat sekitar 41% sampah organik dari total sampah keseluruhan yang didominasi oleh sampah sisa makanan. Namun, menurut data Badan Pusat Statistik yang dikeluarkan pada tahun 2018 hanya 1,2% saja masyarakat yang mendaur ulang sampahnya. Rumah tangga menjadi salah satu penyumbang sampah terbesar di Indonesia. Jumlah rumah tangga di Desa Kedamean terhitung sebanyak 1940 yang berarti 32% dari total keseluruhan penduduk. Salah satu pemanfaataan sisa sampah organik adalah sebagai Pupuk Organik Cair (POC). Melalui alat Komposter, sampah organik rumah tangga dapat dimanfaatkan menjadi Pupuk Organik Cair (POC) melalui proses pengomposan dengan memanfaatkan tong bekas. Oleh karena itu, kegiatan pengabdian masyarakat dilaksanakan untuk memberikan edukasi serta penyuluhan kepada masyarakat Desa Kedamean tentang pengolahan sampah rumah tangga. Kegiatan ini mendapatkan respon positif dan antusias yang tinggi dari masyarakat Desa Kedamean. Melalui kegiatan ini, masyarakat Desa Kedamean memperoleh ilmu dan keterampilan baru untuk meningkatkan produktifitas. Kata kunci: Desa Kedamean; gresik; pengolahan sampah organik; komposter; pupuk organik cair. AbstractKedamean Village is one of the villages in the Kedamean District, the southern part of Gresik Regency. The majority of the residents of Kedamean Village have a livelihood as farmers and factory workers. Based on data from the Ministry of Environment and Forestry 2020, in Gresik Regency, East Java Province, there are around 41% organic waste of the total waste, which is dominated by food waste. However, according to data from the Central Statistics Agency released in 2018, only 1.2% of people recycle their waste. Households are one of the biggest waste contributors in Indonesia. The number of households in Kedamean Village is 1940, which means 32% of the total population. One of the utilizations of the remaining organic waste is as Liquid Organic Fertilizer (LOF). Through the Composter tool, household organic waste can be used as Liquid Organic Fertilizer (LOF) fertilizer through the composting process using used barrels. Therefore, community service activities are carried out to provide education and counseling to the people of Kedamean Village regarding household waste management. This activity received a positive and enthusiastic response from the people of Kedamean Village. Through this activity, the people of Kedamean Village gain new knowledge and skills to increase productivity. Keywords: Kedamean Village; gresik; organic waste processing; composter; liquid organic fertilizer.

Abstract

Trains have become a reliable mode of land transportation as they can avoid traffic congestion, operate on structured schedules, and offer high passenger and freight capacity. Technological advancements have led to the development of high-speed trains capable of traveling over 300 km/h on dedicated, unobstructed tracks, enhancing travel efficiency and regional connectivity. In Indonesia, the Jakarta–Surabaya high-speed rail project is expected to facilitate mobility, reduce congestion on the Pantura corridor, and complement conventional lines such as the Pasar Turi–Lamongan route. This study aims to analyze the horizontal and vertical alignment design, rail elevation dimensions, and the location of gradient transitions on the high-speed rail line between Pasar Turi and Lamongan stations. The geometric planning of the high-speed rail uses references from Minister of Transportation Regulation No. 7 of 2022 and the book Jalan Rel by Suryo Hapsoro Tri Utomo, with secondary topographic data from Google Earth Pro processed using Global Mapper and Civil 3D. The results indicate that the horizontal alignment is designed with speeds below 350 km/h—specifically 300 km/h, 250 km/h, and 120 km/h—to avoid overlap in closely spaced curves, while the vertical alignment is planned for a design speed of 350 km/h with concave and convex vertical radii of 25,000 meters and a gradient of less than 2%. The study concludes with a rail elevation of 175 mm, curve radii of 8,000 meters for 350 km/h, eight SCS-type curves with some lower-speed segments to prevent spiral overlap, and a vertical alignment on an elevated track with eight curve points, a radius of 25,000 meters, and a maximum gradient of 2%.
