Abstract

Mikroplastik pada biota perairan merupakan salah satu permasalahan global yang dihadapi sekarang ini. Salah satu biota perairan yang diketahui mengakumulasi mikroplastik adalah kerang darah (Anadara granosa). Penelitian ini bertujuan untuk mengidentifikasi jenis dan kelimpahan mikroplastik serta menganalisis korelasi antara kelimpahan mikroplastik dengan ukuran kerang darah. A. granosa dengan ukuran yang berbeda (kecil, sedang dan besar) dikumpulkan dari hasil tangkapan nelayan di Kabupaten Penajam Paser Utara. Proses identifikasi mikroplastik pada A. granosa menggunakan metode mikroskopis secara visual. Berdasarkan hasil identifikasi, ditemukan 4 tipe mikroplastik yang ditemukan pada daging kerang yang didominasi oleh tipe fiber (507 partikel), fragmen (273 partikel), film (194 partikel) dan pellet (15 partikel). Kelimpahan mikroplastik yang terdapat pada daging A. granosa adalah tipe fiber (11,3 partikel/ind), fragmen (6,07 partikel/ind), film (4,31 partikel/ind), dan pellet (0,33 partikel/ind). Tipe fiber merupakan yang paling banyak ditemukan, yaitu 507 partikel per individu. Warna hitam sebanyak 289 partikel mendominasi pada tipe mikroplastik yang ditemukan. Hubungan antara kelimpahan mikroplastik dan ukuran kerang (panjang dan berat) memiliki tingkat korelasi sangat kuat dan signifikan (p < 0,05).

Abstract

Waste is one of the problems for people all over the world, marine debris can come from community activities from the mainland or from the coast. Most of the activities of coastal communities may produce waste including fishing and tourism activities. Research on plastic waste in the Tourism Beach area of Muara Badak District was conducted to identify the type of mesoplastic, analyze the total weight, density and proportion of mesoplastic and determine differences in mesoplastic. This research was conducted at two tourist beach locations, namely Panrita Lopi Beach and Jingga Beach. The research method used was Purpusive Sampling method with recycling and making transect lines with a size of 100 m × 20 m, followed by dividing the transect into 5 lanes measuring 5 m x 5 m. Four types of mesoplastic were found, namely film, fiber, fragment and styrofoam. The amount of trash found on both beaches was 53 particles with the number of particles on Panrita Lopi Beach as many as 32 particles and Jingga Beach was 21 particles. The results of the composition of the percentage of waste obtained at Panrita Lopi Beach were 50% for fragment types and at Jingga Beach for 71% for filament types. The most common amount of trash found was at Panrita Lopi Beach, this was due to the fact that the number of visitors was greater than that of Pantau Jingga.  The relationship between length and weight of waste at Panrita Lopi Beach was 94% while at Jingga Beach it was 58%.

Abstract

Aquatic insects play a crucial role in ecological systems because they are sensitive to environmental changes, indicating whether an environment is healthy or polluted. The vast biodiversity in morphology, physiology, and adaptive behavior among insect species on Earth has led to numerous scientific studies using insects as models. Population dynamics studies, for instance, often rely on the evolution of insect populations. The objective of this research is to explore the types of aquatic insects present, as well as their diversity, evenness, and dominance levels. The study found 4 orders and 4 families totaling 180 individuals on the leaf litter of water lettuce. The diversity index of aquatic insects on the water lettuce leaf litter was categorized as low. The evenness index was categorized as small. The dominance index ranged from low to moderate to high categories.

Abstract

Plastic waste poses a significant threat to the global environment, particularly in coastal and marine ecosystems. Among its various forms, mesoplastics, measuring between 5 and 25 mm have attracted considerable attention. This study aims to identify and analyze the types, weights, quantities, compositions, and densities of mesoplastics found along Manggar Beach, a tourist destination in Balikpapan City, East Kalimantan. Sampling was conducted in two periods: April (Period I) and August (Period II) of 2022. A purposive sampling method was applied using a 100-meter transect line divided into 5x5 meter lanes, followed by the placement of 1x1 meter quadrats. In Period I, four types of mesoplastics were identified as film, fiber, fragments, and styrofoam, while only film was detected in Period II. A total of 43 mesoplastic particles (weighing 9.45 grams) were recorded in Period I, compared to just 5 particles (0.15 grams) in Period II. By weight, styrofoam made up the largest proportion (49%) in Period I, whereas film accounted for 100% in Period II. The average mesoplastic density observed in this study was 0.38 particles per square meter.

Abstract

Mangrove (bakau) is one of the coastal plants that might function socially, ecologically and economically. One of the coastal areas of East Kalimantan that has experienced damage due to human activities is in Bontang City, specifically Telok Bangko. Therefore, planting bakau seedlings is one of the efforts to maintain the bakau ecosystem in the coastal areas of Bontang City. The purpose of this community service activity is to increase knowledge and understanding of the importance of mangrove in coastal areas by planting mangrove seedlings. This community service activity was carried out on September 29, 2024 in the Telok Bangko mangrove tourism area, Bontang City. The method used in this activity was lecture and followed by direct practice in the field. The results of this activity were 500 mangrove seedlings (Rizophora mucronata) were planted at the location of the activity by students and academics of Mulawarman University. The results of this activity could increase knowledge and understanding for each participant in determining the right planting location, type, how to plant mangroves and evaluate activities. This activity is also expected to benefit the community both economically and ecologically in the Telok Bangko mangrove area. The process of evaluating activities must be carried out to support the success of this activity, such as maintenance, periodic data collection (monitoring) of mangrove seedlings (% survival rate) that have been planted by participants.Mangrove (bakau) merupakan salah satu tumbuhan pesisir yang dapat berfungsi secara sosial, ekologi dan ekonomi. Salah satu kawasan pesisir Kalimantan Timur yang  telah mengalami kerusakan akibat aktivitas manusia terdapat di Kota Bontang, khususnya Telok Bangko. Karenanya, menanam bibit bakau merupakan salah satu usaha untuk mempertahankan ekosistem bakau di wilayah pesisir kota Bontang. Tujuan dari kegiatan ini adalah untuk meningkatkan pengetahuan dan pemahaman tentang pentingnya bakau di wilayah pesisir dengan cara menanam bibit bakau. Kegiatan pengabdian masyarakat ini dilakukan pada tanggal 29 September 2024 di kawasan wisata mangrove Telok Bangko, Kota Bontang. Metode ceramah dan praktek langsung merupakan metode yang dilakukan di kegiatan pengabdian masyarakat ini. Hasil kegiatan yang didapatkan dari kegiatan ini adalah bibit bakau (Rizophora mucronata) telah ditanam sebanyak 500 bibit di lokasi kegiatan oleh para siswa dan akademisi Universitas Mulawarman. Hasil kegiatan ini dapat meningkatkan pengetahuan dan pemahaman kepada setiap  peserta dalam penentuan lokasi penanaman, jenis, cara menanam bakau dan evaluasi kegiatan secara tepat. Kegiatan ini juga diharapkan dapat bermanfaat bagi masyarakat baik secara ekonomi dan ekologi di kawasan mangrove Telok Bangko. Proses evaluasi kegiatan harus dilakukan untuk mendukung keberhasilan dari kegiatan ini, seperti pemeliharaan, pendataan berkala (monitoring) bibit bakau yang hidup (% survival rate) yang telah ditanam oleh peserta kegiatan.
