Abstract

Pelabuhan Tanjung Emas, Semarang, Jawa Tengah termasuk ke dalam salah satu fasilitas pelabuhan di Indonesia yang menaungi beberapa industri di dalamnya. Lokasi penelitian kali ini bertempat di salah satu fasilitas pelabuhan yaitu Dermaga Nusantara yang secara umum memiliki aktivitas pelabuhan seperti bongkar muat batu bara, pasir, dan log kayu menggunakan alat berat seperti Exavator dan Wheel Loader. Adanya banyak aktivitas pelabuhan dapat dikatakan sebagai faktor yang dapat mempengaruhi keadaan atau baik buruknya air laut serta kadar timbal (Pb) pada air laut di area Dermaga Nusantara. Penelitian ini dilakukan untuk mengetahui kualitas air laut, menganalisis kadar logam berat pada air laut dan menganalisis tindakan pencegahan yang dapat dilakukan untuk meminimalisir timbulnya pencemaran laut. Analisis kualitas perairan menggunakan alat ukur thermometer digital, pH meter, DO meter, secchi disk, dan refractometer. Pengujian kandungan timbal (Pb) menggunakan alat AAS dilakukan di Laboratorium Teknik Lingkungan Universitas Diponegoro. Hasil pengukuran suhu pada kisaran 30,5-32,2°C; nilai pH pada kisaran 6,35-7,56; nilai dissolved oxygen (DO) pada kisaran 5,22-8,51 mg/l; nilai kecerahan pada kisaran 3,18-3,52 meter; dan nilai salinitas pada kisaran 31-35 ppt.

中爪哇三宝垄市 Tanjung Emas 港水域的水质和海水重金属铅 (Pb) 含量分析

印尼中爪哇三宝垄的丹绒埃玛斯港是印尼的港口设施之一，其中有多个行业。此次的研究地点位于其中一个港口设施，即 Nusantara 码头，该码头通常有使用挖掘机和轮式装载机等重型设备装卸煤炭、沙子和原木等港口活动。可以说，许多港口活动的存在是影响 Nusantara 码头地区海水状态或好或坏以及海水中铅（Pb）含量的一个因素。本研究旨在确定海水质量，分析海水中的重金属含量，并分析可采取的预防措施，以尽量减少海洋污染的发生。水质分析使用了数字温度计、pH 计、溶解氧计、秒速盘和折射仪。使用 AAS 设备对铅（Pb）含量的测试是在 Diponegoro 大学环境工程实验室进行的。温度测量结果在 30.5-32.2°C 之间；pH 值在 6.35-7.56 之间；溶解氧 (DO) 值在 5.22-8.51 mg/l 之间；亮度值在 3.18-3.52 米之间；盐度值在 31-35 ppt 之间。铅（Pb）含量的检测结果范围为 0.390 - 0.640 毫克/升。水质测量值仍被归类为符合质量标准，但根据印度尼西亚共和国 2021 年关于实施环境保护和管理的第 22 号 PP 和 2004 年关于港口海水质量标准的第 51 号 KepMen LH，铅含量测试结果仍超出质量标准。印尼中爪哇三宝垄的丹绒埃玛斯港是印尼的港口设施之一，内有多个行业。此次的研究地点位于其中一个港口设施，即 Nusantara 码头，该码头通常有港口活动，如使用挖掘机和轮式装载机等重型设备装卸煤炭、沙子和原木。这项研究旨在确定海水质量，分析海水中重金属的含量，并分析可采取哪些预防措施来尽量减少海洋污染。使用数字温度计、pH 计、溶解氧计、秒速盘和折射仪分析水质。在迪波内戈罗大学环境工程实验室使用 AAS 工具对铅（Pb）含量进行了检测。温度测量结果在 30.5-32.2°C 之间；pH 值在 6.35-7.56 之间；溶解氧 (DO) 值在 5.22-8.51 mg/l 之间；亮度值在 3.18-3.52 米之间；盐度值在 31-35 ppt 之间。铅（Pb）含量的检测结果范围为 0.390 - 0.640 毫克/升。根据印度尼西亚共和国 2021 年关于实施环境保护和管理的第 22 号 PP 和 2004 年关于港口海水质量标准的第 51 号环境部长令，水质测量值仍被归类为符合质量标准，但铅含量检测结果仍超出质量标准。
