Abstract

Tourist activity significantly impacts coastal ecosystems, often leading to increased marine debris pollution. This study examines the influence of tourism on beach cleanliness by analyzing marine debris composition, abundance, and Clean Coast Index (CCI) at four recreational beaches in Prigi Bay, Trenggalek, Indonesia (Cengkrong, Prigi, Karanggongso, and Mutiara). Sampling was conducted in March–April 2024, using a 5×5 m quadrat transect method placed at 20 m intervals along the shoreline in the backshore zone. The Mann-Whitney U test was applied to assess differences in debris accumulation between weekdays and weekends. Results indicated that plastic debris was the dominant type across all sites, with debris abundance slightly higher on weekends (54%) than weekdays (46%). Moreover, the mass of accumulated debris was significantly greater on weekends (1.93 items.m⁻², 8.86 g.m⁻²) than on weekdays (1.57 items.m⁻², 4.69 g.m⁻²), primarily due to an increase in larger debris items (10–100 cm), likely associated with tourism-related waste such as food packaging and recreational items. Despite these fluctuations, all beaches exhibited "extremely dirty" CCI scores (>20), indicating persistent pollution beyond tourism activity. Additional contributing factors may include inefficient waste management, fishing-related debris, and marine transport mechanisms. These findings underscore the urgent need for comprehensive waste management strategies, including source reduction, regular cleanups, improved waste disposal infrastructure, and public awareness campaigns, to mitigate long-term environmental and socio-economic impacts in Prigi Bay. Furthermore, integrating this measure into sustainable coastal tourism planning is crucial to balance recreational use with environmental preservation.

Abstract

Bacteria are microscopic organisms, and a small portion of them are pathogenic or harmful to living organisms. One example is bacteria that cause damage and decay in captured Tuna fish (Thunnus sp.) off the coast of Kondang Merak, Malang. Therefore, to determine the genus of bacteria found in Tuna fish (Thunnus sp.), bacterial morphology identification was conducted. Bacterial morphology identification was performed using methods involving the identification of colony and cell morphology, as well as bacterial respiration tests to enhance genus prediction accuracy. Bacterial morphology identification involved several testing stages, including Gram-staining, cell observation and measurement, motility testing, and bacterial respiration testing. The bacterial isolation samples from Tuna fish (Thunnus sp.) on TSA media consisted of 8 samples, namely 1a, 1b, 2a, 2b, 3, 4a, 4b, and 5, which were differentiated based on bacterial colony morphology. Based on the results of colony morphology identification, cell morphology, and respiratory testing, all 8 bacterial samples were manually identified with reference to identification books. The identification results showed that several samples had similar morphological characteristics. The bacterial morphology identification results for samples 2a and 2b were identified as belonging to the genus Aeromonas; samples 4a and 4b were classified into the genus Mesophilobacter; sample 1a was categorized into the genus Carnobacterium; and samples 1b, 3, and 5 belonged to the genus Vibrio.

Abstract

Senyawa organik volatil atau volatile organic compounds (VOC) adalah kelompok senyawa yang sering ditemukan di lingkungan perairan yang memiliki dampak negatif pada ekosistem dan kesehatan manusia. Keberadaan VOC di perairan dapat disebabkan oleh produksi dan penggunaan senyawa ini secara berkepanjangan. Sungai Sedati terletak di daerah perkotaan telah menerima masukan senyawa ini dari kegiatan rumah tangga, bahan baku industri, pertanian dan budidaya perikanan. Pendeteksian VOC di badan dan muara Sungai Sedati dilakukan menggunakan Solid Phase Microextraction (SPME) dan Gas Cromatography-Mass Spectrometry (GCMS). Selain itu, penelitian ini juga mengevaluasi kualitas perairan berupa pH, DO, salinitas, suhu, dan arus. Total 39 senyawa diperoleh dari Perairan Sedati, dimana senyawa-senyawa tersebut digunakan sebagai bahan kimia industri, bahan kimia farmasi, produk pembersih, produk perawatan pribadi, plasticizer, dan pestisida. Penggunaan tertinggi sebanyak 17 senyawa digunakan sebagai bahan kimia industri dan tujuh senyawa sebagai pestisida. Cemaran VOC didominasi oleh fenol (2,4-di-tert-butilfenol; 3,5-di-tert-butilfenol). Analisis kualitas air menunjukkan bahwa kualitas Perairan Sedati masih dalam ambang batas baku mutu air sungai kelas III dan baku mutu air laut. Penelitian ini memberikan informasi mengenai potensi dampak VOC, dan pentingnya pengelolaan limbah perkotaan yang lebih berkualitas untuk ekosistem perairan dan kesehatan manusia.  Volatile organic compounds (VOCs) are a group of chemicals that are frequently detected in aquatic environments, and show negative impacts on ecosystem and human health. The existence of VOCs in the waters may be obtained from their massive production and application. The Sedati River is located in an urban area that has received impacts from household activities, industrial raw materials, agriculture, and aquaculture. The detection of VOCs in the body and the river mouth of Sedati River was determined by Solid Phase Microextraction (SPME) and Gas Chromatography-Mass Spectrometry (GCMS). Water quality of the Sedati River was evaluated, namely pH, DO, salinity, temperature, and water current. A total of 39 compounds were detected in the Sedati River. Most of them were used in industrial chemicals, pharmaceutical chemicals, cleaning products, personal care products, plasticizers, and pesticides. 17 compounds were highly used as industrial chemicals, whereas seven compounds were lowly used as pesticides. The phenol (2,4-Di-tert-butylphenol; 3,5-Di-tert-butylphenol) was a dominant compound in the Sedati River. The water quality was in agreement with the water quality standards. This study provides information about the impacts of VOC in the water and the importance of water quality treatments for healthy ecosystems and humans.

Abstract

Desa Sidoasri, Kabupaten Malang, memiliki potensi ekowisata bahari yang tinggi namun menghadapi tekanan ekologi dan kelembagaan lokal yang terbatas. Program ini bertujuan memberdayakan Pokmaswas dan masyarakat pesisir agar bertransformasi dari pengguna pasif menjadi pengelola aktif ekowisata berkelanjutan. Metode yang digunakan adalah pendekatan partisipatif berbasis komunitas melalui survei awal, FGD, pelatihan Training Ecodiver (selam dasar, identifikasi biota, pemantauan terumbu, dokumentasi), sarasehan desa, pendampingan intensif, serta evaluasi formatif–sumatif. Hasil menunjukkan: (i) penilaian potensi wisata (panorama pantai, trekking, snorkeling–diving, canoeing, GT fishing) memperoleh skor tinggi pada keunikan ekosistem, keterkaitan antarhabitat, dan keterwakilan ekosistem pesisir; (ii) partisipasi, motivasi, dan kapasitas kelembagaan masyarakat meningkat, tercermin dari keterlibatan dalam pemantauan terumbu, pengelolaan homestay, promosi digital, serta penguatan rencana kerja Pokmaswas; (iii) jejaring komunitas–pemerintah–akademisi menguat dan membuka peluang tindak lanjut. Disimpulkan bahwa konservasi harus menjadi prasyarat pengembangan ekowisata, dengan paradigma “konservasi sebagai investasi” untuk menjaga daya tarik destinasi dan manfaat ekonomi lokal. Ke depan disarankan institusionalisasi SOP dan insentif konservasi, monitoring jangka panjang berbasis komunitas, perluasan kemitraan lintas sektor, serta integrasi adaptasi iklim dan pengendalian spesies invasif dalam paket ekowisata Sidoasri.

Abstract

Senyawa kimia yang berasosiasi dengan sampah plastik di laut dapat terjadi karena bahan dari produk plastik itu sendiri atau kontaminan kimia yang berada di lautan dan terakumulasi pada plastik saat menjadi sampah laut. Senyawa kimia yang berasosiasi dengan sampah plastik di lautan adalah POPs, PAH, TPH. Kelompok senyawa tersebut umumnya menyebabkan pencemaran lingkungan dan masalah kesehatan seperti kanker, alergi serta iritasi, mutasi genetik dan merusak susunan saraf. Tujuan dari penelitian ini adalah mengidentifikasi komposisi senyawa organik volatil yang berasosiasi dengan makroplastik di pantai selatan, Kabupaten Malang serta mengetahui persentase dari senyawa kimianya dan mengetahui potensi dampak dari senyawa organik volatil yang berasosiasi dengan sampah laut. Pengambilan sampel penelitian dibuat menjadi enam stasiun di sepanjang Pesisir Kabupaten Malang. Sampah akan diambil menggunakan metode purposive sampling dan metode composite sampling. Sampel yang sudah dikumpulkan dipotong kecil lalu diekstraksi dengan metode maserasi menggunakan pelarut benzena dan setelah itu diidentifikasi menggunakan GC-MS. Hasil penelitian menunjukkan bahwa terdapat enam senyawa kimia yang dominan yaitu seperti trans -2-Chloro -3 - (1,1 - dimethylehyl) cyclohexanone (PAH); 3-Methyl-1,1-diphenyl-1,2-butanediol (POP); 4,4-Dimethyl-1-hydroxy-2-cyclopentene (POP); 7-Hydroxy-7-phenyl-3,9-diisopropyl-2,10-dioxadispiro (TPC); Benzenemethanol,.alpha.-phenyl-(CAS), Diphenylmethanol (PAH); Cyclohexanone,3-(3,3-dimethylbutyl) (CAS) (3,3Dimethylbuthyl) Cyclohe xanone (POP). Hampir semua senyawa kimia yang teridentifikasi berpengaruh buruk terhadap lingkungan. Senyawa-senyawa tersebut merupakan bahan baku dari pembuatan produk plastik, parfum, deterjen, solar, alat kosmetik, serta bahan kimia farmasi.   Chemical compounds associated with plastic waste in the sea can occur due to materials from the plastic product itself or chemical contaminants that are in the ocean and accumulate in plastic when it becomes marine waste. Chemical compounds associated with plastic waste in the ocean are POPs, PAH, and TPH. These groups of compound generally cause environmental pollution and health problems such as cancer, allergies and irritation, genetic mutations and damage to the nervous system. The aim of this study was to identify the composition of volatile organic compounds associated with macroplastics in South Coastal of Malang, as well as to determine the percentage of chemical compounds and determine the potential impact of volatile organic compounds associated with marine debris. The plastic samples were collected from six stations in the coastal of Malang Regency. Plastic wastes were collected using the purposive sampling method and composite sampling method. The samples that had been collected were cut into small pieces and then extracted using the maceration method using benzene solvent and then identified using GC-MS. The results showed that there were six dominant chemical compounds, namely trans - 2 - Chloro - 3 - (1,1 - dimethylehyl) cyclohexanone (PAH); 3-Methyl-1,1-diphenyl-1,2-butanediol (POP); 4,4-Dimethyl-1-hydroxy-2-cyclopentene (POP); 7-Hydroxy-7-phenyl-3,9-diisopropyl-2,10-dioxadispiro (TPC); Benzenemethanol,.alpha.-phenyl-(CAS) Diphenylmethanol (PAH); Cyclohexanone,3-(3,3-dimethylbutyl)-(CAS) (3,3Dimethylbuthyl) Cyclohexanone (POP). Almost all chemical compounds which had been identified showed negative effects in the environment. These compounds are raw materials for the manufacture of plastic products, perfume, detergent, diesel, cosmetic equipment, and pharmaceutical chemicals.

Abstract

Enrichment process seperti proses upwelling, mixing, atau river runoff, sangat diperlukan dalam meningkatkan kesuburan perairan, namun demikian enrichment process yang berlebihan pada suatu perairan berpotensi pada perubahan keseimbangan suatu ekosistem yang ditandai dengan adanya perubahan struktur komunitas plankton. Perairan Probolinggo yang merupakan bagian dari Selat Madura, diduga mengalami kondisi ini. Tujuan dari penelitian ini adalah untuk menganalisis pengaruh konsentrasi nutrien terhadap struktur komunitas plankton di Perairan Probolinggo. Pengambilan sampel dilakukan pada bulan Juli dan September 2023 dengan menggunakan metode purposive sampling. Parameter kualitas air yang diukur meliputi nitrat, ortofosfat, silikat, suhu, salinitas, pH, DO, dan kecerahan. Sampel plankton diambil menggunakan plankton net, kemudian diidentifikasi dan dianalisis menggunakan indeks ekologi. Hasil penelitian menunjukkan konsentrasi nitrat berkisar antara 0,04–2,03 mg/L, sedangkan ortofosfat dan silikat relatif homogen dengan nilai 0,02–0,03 mg/L dan 0,02–0,10 mg/L, dengan nilai indeks keanekaragaman plankton (H’) antara 0,62–1,45. Analisis PCA menunjukkan nitrat menjadi variabel dominan terhadap variasi struktur komunitas plankton di Perairan Probolinggo. Kelimpahan fitoplankton lebih tinggi dibandingkan zooplankton, terutama pada titik yang memiliki konsentrasi nutrien relatif tinggi (Titik 1 dan 2 di bulan Juli). Namun, tingginya kelimpahan tersebut tidak diikuti dengan keanekaragaman yang tinggi (H’ lebih rendah), sehingga menunjukkan adanya pergeseran struktur komunitas plankton menuju kondisi yang kurang beragam. Temuan ini mengindikasikan bahwa enrichment nutrient, khususnya nitrat berkontribusi terhadap perubahan struktur komunitas plankton di Perairan Probolinggo. Penelitian diharapkan dapat memberikan gambaran mengenai kondisi ekosistem setempat serta menjadi dasar bagi pengelolaan perikanan dan sumber daya pesisir secara berkelanjutan.   Enrichment processes such as upwelling, mixing, or river runoff can increase water fertility, but excessive enrichment has the potential to disrupt ecosystem balance, as reflected in changes to plankton community structure. The waters of Probolinggo, part of the Madura Strait, are suspected of experiencing this condition. This study aimed to analyze the effect of nutrient concentration on plankton community structure in Probolinggo Waters. Sampling was conducted in July and September 2023 using purposive sampling. Measured water quality parameters included nitrate, orthophosphate, silicate, temperature, salinity, pH, DO, and brightness. Plankton samples were collected with a plankton net, then identified and analyzed using ecological indices. Results showed nitrate concentrations ranged from 0.04 to 2.03 mg/L, while orthophosphate and silicate were relatively homogeneous (0.02–0.03 mg/L and 0.02–0.10 mg/L, respectively). Plankton diversity index (H’) values ranged from 0.62 to 1.45. PCA analysis indicated that nitrate was the dominant variable influencing variation in plankton community structure. Phytoplankton abundance was higher than zooplankton, especially at stations with relatively high nutrient concentrations (stations 1 and 2 in July). However, this abundance was not accompanied by higher diversity (lower H’), indicating a shift in community structure towards reduced diversity. These findings suggest that nutrient enrichment, particularly nitrate, plays a significant role in altering plankton community structure in Probolinggo waters. This study provides insight into local ecosystem dynamics and serves as a basis for sustainable fisheries and coastal resource management.
