Abstract

Pantai Serang merupakan pantai pariwisata yang terletak di Kabupaten Blitar, Jawa Timur. Kegiatan pariwisata ini dapat memicu pencemaran sampah laut. Sampah laut yang mencemari pantai dikategorikan menjadi sampah plastik, kertas, kayu, kain, kaca, logam, karet, dan bahan berbahaya. Sampah plastik yang banyak ditemukan juga dapat terdegradasi menjadi mikroplastik yang dapat dijumpai dengan variasi bentuk, ukuran, dan warna yang beragam. Sampah laut dan mikroplastik dapat menimbulkan efek buruk terhadap lingkungan dan biota laut. Tujuan penelitian adalah untuk mengetahui kelimpahan sampah laut dan mikroplastik di Pantai Serang, Kabupaten Blitar, Jawa Timur. Sampel sampah laut dan mikroplastik dikumpulkan dengan metode random sampling pada lima titik sampling yang berbeda menggunakan transek kuadrat. Sampel sampah laut dan mikroplastik dianalisis secara visual berdasarkan jenis dan ukurannya. Hasil analisis menunjukkan bahwa di Pantai Serang, Kabupaten Blitar, Jawa Timur terdapat sampah laut dan mikroplastik dengan ukuran 1–5 mm atau large microplastic particles (LMP). Sampah laut yang ditemukan didominasi ukuran 5-10 cm. Sampah plastik mendominasi kelimpahan sampah laut di Pantai Serang (75.49%) disusul dengan kertas (18.87%), karet (3.31%), dan lainnya (<1%). Hal ini juga memicu banyaknya pencemaran mikroplastik. Mikroplastik dengan ukuran 1–5 mm yang terdapat pada Pantai Serang, Kabupaten Blitar didominasi jenis foam (57%) yang kemudian disusul dengan fragment (33%) dan film (10%). Kelimpahan sampah laut dan mikroplastik utamanya disebabkan oleh aktivitas antropogenik pariwisata dan perikanan tangkap.

Abstract

Lamongan Regency has a fairly progressive fisheries sector with high fishing activity, such as the fishing industry and ports, especially in the Paciran and Brondong subdistricts. On the other hand, rapid fishing activities can also cause the entry of pollutants such as heavy metals and have the potential to reduce water quality in the area. The aim of this research is to analyze water conditions based on physical and chemical parameters as well as the distribution of dissolved heavy metal Hg and Pb in the fisheries industrial area and port of Lamongan Regency. The research was carried out using a purposive sampling method at seven stations along the waters of both Brondong and Paciran Districts. The data used in this research includes water quality parameters and dissolved heavy metal Hg and Pb. Analysis of heavy metal content was carried out in the laboratory using an Atomic Absorption Spectroscopy (AAS) instrument. The results showed that the heavy metal Hg at all stations was not detected by AAS because its concentration was very low. Meanwhile, the heavy metal Pb shows varying values at all stations with a range of 0.08 mg/L – 1.88 mg/L. The concentration of the heavy metal Pb at most location points has exceeded the limits set by Indonesian Government Regulations. The results of statistical analysis show that there is a relationship between temperature and pH and the concentration of the heavy metal Pb in water.

Abstract

Avicennia marina is a species of mangrove that has been studied extensively for its capability to uptake and accumulate heavy metals. Since Avicennia marina was found in the Wonorejo Mangrove ecosystem, which confirmed received anthropogenic inputs from Surabaya as the second largest city in Indonesia, the effectivity of bioaccumulation and translocation metals Cd, Zn, and Pb was studied. The sediments, roots, stems and leaves of Avicennia marina were collected in three sites in Wonorejo Mangrove Ecosystem, East Surabaya. The measurement of Cd, Zn and Pb was conducted by ICP-MS. To assess the effectiveness of accumulation and translocation capability, Bioconcentration Factor (BCF) and Translocation Factor (TF) were calculated. The results showed that the distribution of heavy metals Cd and Pb in the organs of the mangrove Avicennia marina exhibited distinct patterns. Although both of them are considered as non-essential elements, Cd tends to distribute evenly until leaves parts, while Pb tends to retain in the roots. In the case of Zn, as an essential element, the uptake was more intense compared to non-essential elements and mobilized until the leaves parts. Interestingly, once all metals reach the stem, they might transfer to the leaves as shown by TF values more than 1. Therefore, Avicennia marine has an effective defense mechanism in the presence of metals by regulating the accumulation and translocation of metals into detoxifying organs.

Abstract

Marine debris has emerged as a significant environmental issue of growing global concern, closely linked to pollution and its impact on the environment. Understanding the distribution of marine waste in coastal areas is crucial, especially considering that beaches are key sites for various human activities such as tourism, fishing, and shipping. To address this, a study was conducted to analyze the composition of marine debris on three beaches in Banyuwangi Regency, East Java. The study took place in July and August of 2023, focusing on Boom, Cacalan, and Cemara beaches. Marine debris was collected along the coastline in 5 x 5 m transects, spaced 20 m apart, to identify and quantify the types of waste. The findings revealed that Boom Beach had the highest percentage of rubbish (46%), followed by Cemara Beach (30%) and Cacalan Beach (24%). Additionally, the highest abundance of rubbish per area was found at Boom Beach (5.97 ± 16.64 item/m2), Cemara Beach (3,92 ± 11,36 item/m2), and Cacalan Beach (3,12 ± 5,27 item/m2). Boom Beach and Cemara Beach were primarily dominated by plastic waste, while at Cacalan Beach, plastic waste and broken glass were found in nearly equal proportions. The calculation of the Clean Coast Index (CCI) indicated that all three beaches were significantly polluted. As a result, there is a clear need for focused attention on waste management at tourist beaches to preserve the aesthetics and comfort of beach visitors.

Abstract

Kondang Merak Beach has several community groups that inhabit and manage the beach. One of the local community groups is Bina Karya Mina fishing group. Apart from fishing, which was their main livelihood, this group of fishermen was also proficient in diving and snorkeling. However, due to the lack of training in diving for the fishermen, the diving equipment that is there is not properly utilized. Knowledge about first aid for diving accident victims is also needed not only when a fishermen’s diving accident occurs but can also be used to help tourists when an accident occurs while snorkeling or swimming at the beach. This community service activity aimed to increase the knowledge and skills of the Bina Karya Mina fishing group in terms of diving, especially first aid for accident victims at Kondang Merak Beach, Malang Regency. This activity was divided into three stages of activity, namely the preparation, implementation, evaluation, and reporting stages. The implementation stage of this community service activity was carried out in a hybrid manner, namely socialization material was given online, while practical activities and handover of first aid assistance are carried out offline. Through this activity, it was expected to improve the ability of fishermen in the field of diving. In addition, socialization about first aid kits as supporting equipment to help accident victims was carried out as well so that they could increase the preparedness of fishermen on Kondang Merak Beach in case of an emergency.

Abstract

Characteristics of plastic debris were assessed among two types of beaches on Bawean Island (windward and leeward) to analyze its sources and long-term effects. Plastic debris was collected inside a 5 x 5 meter transect with five transect plots on each beach per 20 meters. Samplings were carried out three times at intervals of seven days from six different beaches. The average abundances of plastic debris were almost similar between leeward (0.1690.123 pcs m-2) and windward beaches (0.8410.577 pcs m-2). On the other hand, in terms of weight, leeward beaches contained a very low value of debris (0.9270.746 g m-2) compared to windward beaches (4.4793.551 g m-2). Sheets on the windward beaches and wholes on the leeward beaches dominate the shape of plastic debris with the average size was 1520 cm. The color on both type of beaches was dominated by white (38%) and blue (12%). The weathering intensity is 48% on the leeward beach and 52% on the windward beach. The absence of significant differences in size, color, and weathering intensity implies that the debris found came from the same source. The large size and low weathering intensity of the plastic debris means that the debris has not been exposed to hydro-oceanographic factors for an extended period and they came from a local source. The difference in abundance and shape of plastic debris suggests that wind still plays a vital role in shaping the characteristics of plastic debris on Bawean Island.Keywords:Marine DebrisPlastic WeatheringWind DirectionMarine PollutionMacroplastic

Abstract

Penelitian ini bertujuan menganalisis perbandingan sampah laut jenis plastik dan jenis non-plastik yang ditemukan di sepanjang pantai Pulau Gili Ketapang, Kabupaten Probolinggo, Jawa Timur. Penelitian dilaksanakan pada bulan Juni 2024 dengan dua kali pengulangan. Stasiun ditentukan berdasarkan aktivitas antropogeniknya yaitu stasiun wisata bagian barat (WB), dermaga bagian utara (DU), dermaga bagian selatan (DS), area bagian timur laut (TL), Pantai Goa Kucing (PGK), dan area bagian barat selatan (BS). Transek garis ditempatkan sepanjang 100 m garis pantai , dan setiap 20 m ditempatkan transek kuadrat berukuran 5 x 5 m, kecuali pada stasiun DS berukuran 1x 1 m. Sampah laut jenis plastik dan non-plastik yang ditemukan dicatat jumlah, ukuran (makro kecil dan makro besar) dan jenisnya. Hasil penelitian menunjukkan kepadatan sampah laut jenis plastik sebesar 14,89 item/m2 dan jenis non-plastik sebesar 5,22 item/m2. Persentase sampah plastik tertinggi ditemukan pada stasiun dermaga utara (DU) dan stasiun dermaga Selatan (DS) dengan kisaran 75-77 %. Sebesar > 86 % ditemukan jenis sampah plastik sekali pakai di semua stasiun penelitian. Dilihat pada ukurannya, kedua jenis sampah laut tersebut didominasi dengan ukuran sampah makro kecil atau 2,5 – 30 cm. Penelitian ini menunjukkan sampah plastik masih menjadi masalah utama di Pulau Gili Ketapang sehingga diperlukan adanya manajemen pengelolaan sampah.

Abstract

Invertebrata laut umumnya ditemukan di wilayah perairan laut terutama area intertidal. Namun, seiring dengan kebutuhan akan makanan dan tempat berlindung, invertebrata laut juga dapat ditemukan di sampah laut organik di daerah pesisir. Penelitian ini bertujuan untuk menganalisis jenis invertebrata yang berasosiasi dengan sampah laut organik dan struktur komunitasnya. Penelitian ini dilakukan di Pesisir Kabupaten Malang khususnya Pantai Sendang Biru dan Pelabuhan Perikanan Pantai Pondokdadap. Sampah organik laut dikumpulkan dari transek garis yang telah ditentukan dengan pengulangan waktu, kemudian dilanjutkan dengan menganalisis komposisi jenis sampah dan invertebrata laut asosiasinya. Komposisi jenis tertinggi sampah organik laut yaitu daun sebesar 67,80% di Pantai Sendang Biru dan 48,29% di Pelabuhan Pondokdadap. Komposisi berat tertinggi sampah organik laut yaitu sabut kelapa sebesar 46,02% di Pantai Sendang Biru dan 68,08% di Pelabuhan Pondokdadap. Sebanyak empat genus invertebrata laut (Melampus, Littoraria, Ligia, dan Platorchestia) ditemukan berasoasi dengan sampah laut organik di Pantai Sendang Biru, sedangkan sebanyak enam genus (Melampus, Ellobium, Littoraria, Nerita, Ligia, dan Platorchestia) ditemukan berasosiasi dengan sampah laut organik di Pelabuhan Pondokdadap. Indeks keanekaragaman invertebrata yang ditemukan pada kedua wilayah bernilai sedang, komunitas dalam kondisi stabil, dan tidak terdapat spesies yang mendominasi. Analisis korelasi menunjukkan hubungan yang positif antara kepadatan jenis sampah organik laut dengan kelimpahan invertebrata laut. Penelitian ini menunjukkan pentingnya pengelolaan sampah organik di daerah pesisir untuk kelangsungan hidup invertebrata laut.

Abstract

The problem of cigarette butts scattered in the Kondangmerak Tourism Beach area, Malang Regency, is a serious concern because of its impact on the environment and coastal ecosystems. Therefore, through community service activities at Kondangmerak Beach, Sumberbening Village, Bantur District, Malang Regency, we will discuss the design and application of special trash bins for cigarette butts as a solution to reduce pollution in the Kondangmerak tourist beach area. The cigarette butt waste disposal bin is made of wood with dimensions of 30 x 50 x 5 cm in the shape of a box and painted yellow. Next, the disposal site is divided into two boxes for disposing of cigarette butts and each box is equipped with a hole the size of the diameter of the cigarette butt for disposal. This design also considers educational aspects through environmental awareness campaigns, to encourage responsible behavior in disposing of cigarette butts in the right place. The application of this trash can involves the active participation of local communities and tourism managers in promoting a clean and healthy environment.
