Abstract

Microplastics are non-degradable contaminants that have been found in many river waters. Microplastics not only pollute water bodies but also become pollutants in river sediments. The Malang area is one of the areas passed by the Brantas River, which is the longest river in East Java and plays an important role for the community. The Brantas River has experienced a decline in water quality related to microplastic contamination. This study aims to analyze the types of microplastics and the abundance of microplastics found in water and sediment in the Brantas Subwatershed Malang Region. This study used a survey method and determined the sampling location point by purposive sampling. Microplastics found in water and sediment samples have the same 3 types, namely fragments, fibers and films. The fragment type was found to dominate in water samples by 38.62% and also in sediment samples by 76.13%. The abundance of microplastics in water was highest at Station 5 at 686.67 particles/m3 and lowest at Station 1 at 396.67 particles/m3. While the abundance of microplastics in the sediment was highest at Station 3 at 2,517.15 particles/kg and lowest at Station 2 at 1,779.93 particles/kg.

Abstract

Ekosistem lamun di wilayah Paciran, Lamongan, Jawa Timur, merupakan habitat bagi komunitas makrozoobentos. Tujuan dari penelitian ini adalah untuk mengetahui struktur komunitas makrozoobentos di wilayah pesisir Paciran dengan metode survei. Sampel makrozoobentos diamati dengan menggunakan transek saat air laut surut di tiga stasiun yang telah ditentukan. Stasiun 1 merupakan wilayah tempat bersandarnya kapal; stasiun 2 adalah daerah dekat pemukiman penduduk dan stasiun 3 di dekat daerah pembenihan ikan atau udang. Hasil penelitian ditemukan 3 filum organisme, yaitu Mollusca, Echinodermata, dan Annelida. Kelimpahan makrozoobentos di tiga stasiun berkisar 486-608 ind/m2, dengan indeks keanekaragaman (H’) sedang (1,68-1,71), indeks keseragaman (E) tinggi (0,70-0,73) dan indeks dominasi (C) rendah (0,23-0,25) dengan kelimpahan relatif tertinggi yaitu pada gastropoda Cerithium granosum dan tidak ditemukan makrozoobenthos yang mendominasi. Berdasarkan hasil penelitian dapat disimpulkan bahwa perlu adanya pemantauan dan penyuluhan bagi warga sekitar lingkungan pantai agar ketersediaan makrozoobentos tersebut tetap lestari.

Abstract

Fitoplankton adalah organisme akuatik yang memegang peranan penting di ekosistem perairan karena merupakan produsen utama dalam ratai makanan. Pertumbuhan fitoplankton sangat tergantung dari ketersediaan nutrient (nitrat dan fosfat) yang ada di perairan. Ranu Grati adalah danau vulkanis yang terletak di Jawa Timur yang banyak dimanfaatkan oleh masyarakat untuk berbagai aktivitas. Aktivitas-aktivitas tersebut umumnya menghasilkan bahan organik yang akan mempengaruhi konsentrasi nitrat dan fosfat sekaligus juga mempengaruhi struktur komunitas fitoplankton di perairan danau. Penelitian ini bertujuan untuk memodelkan hubungan kelimpahan fitoplankton dengan ketersediaan nutrient serta memprediksi komposisi fitoplankton berdasarkan divisi untuk mengetahui struktur komunitasnya dengan pendekatan Generalized Linear Regression. Hasil analisis menunjukkan bahwa nutrient yang berpengaruh signifikan terhadap jumlah amatan fitoplankton adalah konsentrasi fosfat, sedangkan kelimpahan fitoplankton di Ranu Grati cenderung didominasi oleh fitoplankton dari divisi Chlorophyta.

Abstract

Ketersediaan pakan alami dalam budidaya ikan ataupun udang menjadi tantangan, dimana bisa menjadi peluang untuk para pembudidaya agar dapat meningkatkan produksi perikanan budidaya. Pakan alami yang berkualitas tinggi sangat diperlukan untuk mendukung pertumbuhan larva ikan dan udang pada awal mula kehidupan. Pakan alami seperti Chlorella sp. dalam budidaya perikanan tidak bisa sepenuhnya bergantung pada alam sebagai sumber utama, melainkan diperlukan usaha pengkulturan untuk meningkatkan produksi Chlorella sp. sehingga para petambak dapat mengoptimalkan produktivitas budidaya mereka. Metode dalam penelitian ini terdiri dari persiapan bibit mikroalga, persiapan alat kultur, sterilisasi alat dan bahan, proses kultur, dan pemantauan setelah kultur dilakukan. Stoples ukuran 3 liter sebagai wadah kultur skala laboratorium. Kepadatan populasi mikroalga pada setiap sampel ditentukan dengan metode hitung langsung menggunakan haemocytometer dan mikroskop dengan perbesaran 10x. Beberapa faktor lingkungan dapat mempengaruhi pertumbuhan Chlorella sp. ini selama masa kultur seperti kualitas air dalam beberapa kondisi seperti kimia dan mediannya. Parameter fisik seperti suhu, intensitas cahaya, dan aerasi, serta parameter kimia seperti suhu, DO, pH, dan salinitas digunakan untuk mengevaluasi kualitas air. Penggunaan pakan alami sebagai tambahan nutrisi dapat meningkatkan kualitas hasil budidaya udang vaname.

Abstract

This community service program was conducted with the Benur Barokah Group (Tuban Regency), a producer of vannamei shrimp (Litopenaeus vannamei) post larvae at the PL-5 stage. Major constraints included inconsistent natural feed quality, water-quality management based mainly on experience, and limited marketing, leading to low harvest success (≈40% of stocked PL-5) and fluctuating survival rates. The program aimed to improve seed production by mentoring partners on Chlorella sp. microalgae culture as natural feed, training on routine water-quality monitoring, and providing measuring tools (digital thermometer and refractometer), supported by an operational culture module. A website was also developed to broaden marketing reach. Methods included site surveys, socialization and extension sessions, hands-on mentoring, and monitoring and evaluation. Outcomes included improved partner understanding of microalgae culture and key water-quality parameters, availability of monitoring instruments, and the establishment of digital promotional media. Questionnaire-based evaluation indicated highly positive partner responses. Sustainability will be supported by appointing responsible personnel, scheduling routine culture activities and water-quality record keeping, and periodically updating digital marketing content.

Abstract

The Mojomakmur farmer group in Mojorejo Village, Junrejo District, Batu City faces the challenge of abundant goat livestock waste that has not been properly utilized, resulting in unpleasant odors and potential environmental pollution. In fact, this waste has high agronomic value when processed into organic fertilizer to support sustainable agriculture. Limited knowledge, skills, and facilities are the main obstacles hindering effective waste utilization. To address these issues, this community service program was carried out through awareness activities on the importance of livestock-waste management, training on the production of solid and liquid organic fertilizers, and the implementation of appropriate technology that farmers can apply easily and efficiently. In addition, intensive mentoring and continuous evaluation were conducted to ensure that the acquired skills can be independently implemented. This program is expected to promote more environmentally friendly waste management, increase the added value of livestock waste for farmers, and strengthen sustainable agricultural practices.
