Abstract

Subsea pipelines have several risks that can cause damage to the surrounding environment if damage occurs. Several factors can cause subsea pipeline failure, such as: third party errors, corrosion, design errors, and operational errors. Literature and historical reviews of subsea pipeline failures and incidents indicate that third party factors are responsible for 38% of subsea pipeline failures. Common factors from the category of third party errors that can cause pipeline failure include: fishing activities, commercial ship activities (emergency anchoring, dragged anchor, dropped containers, and ship sinking), and ship construction activities. The main focus of this assessment is the analysis of damage to the subsea pipeline caused by the anchor fall. Damage calculations based on the DNVGL RP F107 standard were compared with simulations using the FEM application. Based on the damage analysis carried out, the underwater pipeline was damaged in the protective concrete layer and experienced dents. Therefore, external protection using the gravel buried method is recommended to protect subsea pipelines from falling anchors. The total investment value required for the installation of the shield is Rp. 4,853,181,463.

Abstract

The waste in final disposal site that are not managed properly will have an impact the environment and human health. Leachate from rainwater infiltration or waste decomposition can contaminate groundwater due to leachate seepage into the soil. This research aims to determine the pattern of leachate contaminants migration and to predict the leachate contaminant in groundwater from wells of residents living near the landfill over a certain period. The method used is the Domenico analytical solution, where contaminant transport is influenced by advection, dispersion, retardation, and degradation. Source concentration of model simulation from laboratory tests of leachate samples where COD is 4,960 mg/L, hexavalent chromium is 3.5 mg/L, dissolved lead is 0.034 mg/L, and dissolved aluminium is 1.3 mg/L. The distribution pattern of leachate contaminants shows that the distribution of COD contaminants reaches ± 370 m in the longitudinal direction and ± 100 m in the transverse direction, while the distribution pattern of metal contaminants reaches ± 230 m in the longitudinal direction and ± 70 m in the transverse direction. When variations in the operational age of a landfill are 10, 25, and 50 years, the contaminant content of COD, hexavalent chromium, and aluminium exceeds the required quality standard thresholds, while lead is still within the required quality standard thresholds based on PP Nomor 22 Tahun 2021 (Kriteria Mutu Air Kelas II). Keywords: landfill, leachate, groundwater, analytical solution, contaminant transport.

Abstract

Penelitian tentang komposit berbasis serat berkembang dengan penggunaan bahan serat alam untuk beberapa variasi jenis matrik sintetis dan alami. Komposit dengan penguat serat alam ini semakin intensif dikembangkan. Ini berkaitan dengan meluasnya penggunaan komposit pada berbagai bidang kehidupan serta tuntunan penggunaan material yang murah, ringan, sifat mekanik yang kuat dan tidak korosif, sehingga dapat menjadi bahan alternatif selain logam. Lontar (Borasus flabelifer) adalah jenis palma yang bersifat serba guna. Salah satu aplikasi serat pangkal pelepah daun lontar adalah untuk pembuatan komposit dalam lambung kapal fibre reinforced. Pada penelitian ini akan dibuat komposit dari serat pangkal pelepah daun lontar. Spesimen komposit yang terbentuk dilakukan uji tegangan, regangan dan modulus elastisitas menggunakan 2 variasi komposisi. Hasilnya kemudian dibandingkan dengan nilai kekuatan yang disyaratkan/diizinkan oleh Biro Klasifikasi Indonesia (BKI) volume XIV 2014 rules for nonmetallic material sebagai acuan standar. Hasil pengujian menunjukan bahwa kekuatan tarik, modulus tarik elastisitas dan kekuatan tekuk, modulus tekuk elastisitas komposit yang menggunakan serat pangkal pelepah daun lontar memenuhi standar BKI seperti berikut ini: pengujian tarik variasi 1 spesimen (2) dengan kekuatan  63.714 Mpa, spesimen (2) 436.09 N/mm2 modulus elastisitas dan variasi 2 spesimen (4) dengan kekuatan tarik 70.035 Mpa, dengan modulus elastisitas spesimen (4) 1490.11 N/mm2 untuk pengujian tekuk tidak memenuhi standar di kekutan tekuk di variasi 1 spesimen (1) 15.45 Mpa, variasi 2 spesimen (4) 16.27 Mpa. Tetapi di modulus tekuk elastisitasnya ada yang memenuhi standar dengan hasil di variasi 1 spesimen (1) 949.96 N/mm2, dan modulus variasi 2 spesimen (4) 1534.47 N/mm2. Hasil ini telah memenuhi syarat yang ditentukan oleh BKI FRP (fiberglass reinforced plastics) yaitu 55 N/mm2.   Kata kunci: Komposit, Daun Lontar, Uji tarik, Serat Glass

Abstract

Desa Dharma Camplong merupakan wilayah pesisir yang memiliki potensi strategis sebagai destinasi wisata sekaligus pusat ekonomi berbasis perikanan dan pengolahan hasil laut. Namun, limbah padat yang dihasilkan dari aktivitas masyarakat desa belum optimal pengelolaannya. Tujuan pengabdian masyarakat ini untuk menginisiasi sistem pengelolaan sampah yang terintegrasi melalui difusi ipteks, pendidikan masyarakat melalui sosialisasi, dan partisipasi aktif masyarakat. Metode pelaksanaan meliputi survei lapangan, desain dan pembuatan gerobak dan bak sampah, sosialisasi pengelolaan sampah berbasis masyarakat. serta pembentukan tim pengelola lingkungan. Hasil kegiatan menunjukkan adanya ketersediaan dua unit gerobak angkut dan sepuluh unit bak sampah di titik strategis. Selain itu, adanya kenaikan rata-rata yang signifikan dari seluruh indikator kegiatan sosialisasi dan pelatihan teknis terkait pengelolaan sampah sebesar 52 %. Hal ini menunjukkan bahwa intervensi melalui edukasi berhasil mentransfer informasi secara efektif. Peningkatan tertinggi terjadi pada indikator partisipasi aktif masyarakat dalam pengelolaan sampah seperti keikutsertaan dalam program pengelolaan sampah.
