Abstract

Surface drainage is the regular diversion or disposal of excess water from the land surface through improved natural channels or constructed water channels, if necessary, equipped with the formation and assessment of the land surface for these channels. Campus 1 of Pancasakti University Tegal is located in the coastal area of ​​Tegal City. In some cases, the land surface of Pancasakti Tegal University is shaped or graded to create a slope towards the channel. The different types of surface drainage systems are open channels, humps and depressions, embankments, and building edge drains. Drainage is the natural or artificial removal of surface and subsurface water from an area that has excess water. Internal drainage on most educational sites can prevent severe waterlogging, but many soils require artificial drainage to improve management of excess water. The first step in installing a drainage system is to survey the area and determine the type of system needed. During high tides and high rainfall, water intrusion occurs into the grounds of Pancasakti University Tegal. This involves assessing the amount of rainfall and sea tides in waterlogged areas, the slope of the land, and the type of soil. This will tell us what type and material of drainage system is best for the structure. The drainage problem that often arises is the lack of coordination and synchronization with other infrastructure development. In general, the handling of the drainage system is still partial, so it does not solve the problem of flooding and inundation completely. The purpose of this paper is to review several factors that cause water intrusion in drainage due to high tides causing water flow to be obstructed so that when it rains, water overflows and puddles occur.

Abstract

Pantai Komodo dikembangkan sebagai kawasan eduminawisata melalui berbagai kegiatan edukatif dan pemberdayaan masyarakat pesisir yang mengintegrasikan sektor perikanan, konservasi, dan pariwisata. Namun, dalam proses pengembangannya masih dijumpai sejumlah permasalahan, terutama keterbatasan pengetahuan dan keterampilan nelayan dalam pengelolaan sumber daya, pemanfaatan teknologi, serta pengembangan usaha bernilai tambah. Kondisi tersebut berpotensi menghambat optimalisasi potensi kawasan, sehingga diperlukan kegiatan pengabdian kepada masyarakat yang terarah dan berkelanjutan sebagai upaya peningkatan kapasitas, kemandirian, dan kesejahteraan masyarakat pesisir. Tujuan kegiatan Penguatan Kapasitas Nelayan Melalui Pelatihan Penentuan Zona Tangkap dan Konservasi Laut di Pantai Komodo adalah untuk meningkatkan pengetahuan dan keterampilan nelayan dalam menentukan zona tangkap yang tepat dan efisien berbasis teknologi, sekaligus menumbuhkan pemahaman tentang pentingnya konservasi laut. Kegiatan pengabdian masyarakat dilakukan dengan metode partisipatif melalui survei pendahuluan, koordinasi dengan pemangku kepentingan, sosialisasi, pendampingan, implementasi teknologi sederhana, serta monitoring dan evaluasi. Selama pelaksanaan  program ini meningkatkan keterampilan nelayan dalam penentuan zona tangkap berbasis GPS, memberdayakan ibu-ibu nelayan melalui produksi olahan hasil laut bernilai tambah, membangun substrat budidaya kerang hijau dan rumah semai mangrove, serta menghadirkan aplikasi Smart Fisheries Economy, yang berdampak pada efisiensi produksi, diversifikasi usaha pesisir, pemberdayaan perempuan, dan penguatan branding Eduminawisata Pantai Komodo. Mitra utama yaitu Kelompok Usaha Bersama (KUB Gulamah), Pokdarwis, dan Pokwasmas berperan aktif dalam pelaksanaan program sehingga terbentuk sinergi antara konservasi, pemanfaatan perikanan tangkap, dan pengembangan ekowisata berbasis literasi kelautan. Hasil pre-test dan post-test menunjukkan kenaikan rata-rata nilai dari 56,37 menjadi 58,18, atau meningkat 1,81 poin. Sebanyak 6 peserta mengalami peningkatan, 3 tetap, dan 2 menurun. Secara umum, kegiatan memberikan dampak positif, meskipun peningkatannya masih tergolong moderat dan perlu penguatan materi lanjutan.

Abstract

Population growth and increasing economic activities have raised the demand for durable and high-quality road infrastructure. However, the Asphalt Concrete–Wearing Course (AC-WC), which functions as the surface layer of flexible pavements, often suffers from premature damage such as cracking and deformation due to heavy traffic loads and extreme weather. Therefore, improvements in asphalt mixture materials are necessary. One alternative is the use of liquid latex derived from natural rubber as an additive. Owing to its high elasticity, liquid latex is expected to improve flexibility, crack resistance, and durability of asphalt mixtures. This study aims to evaluate the effect of liquid latex addition on the Marshall characteristics of AC-WC mixtures and to determine the optimum latex content. The research employed laboratory experimental methods using liquid latex contents of 0%, 2.5%, 5%, 7.5%, and 10%, with three specimens prepared for each variation. The evaluated parameters included stability, flow, air voids in the mix (VIM), voids in mineral aggregate (VMA), voids filled with asphalt (VFA), Marshall Quotient (MQ), and density. The results indicate that liquid latex significantly affects all Marshall parameters. However, excessive latex content reduces mixture performance. The optimum condition was achieved at 2.5% liquid latex with an asphalt content of 5.65%, producing a stability of 1102.2 kg, flow of 3.13 mm, VIM of 3.87%, VMA of 17.01%, VFA of 77.26%, MQ of 355.15 kg/mm, and density of 2.297 g/cc. All parameters satisfy the 2018 Bina Marga General Specifications (Revision 2).
