Abstract

Good water quality is very important to support the sustainability of the organisms that live in it. The location of the Semuong River which is close to mining and human activities such as settlements will generally cause environmental problems such as water quality degradation. The research was to determine the Samuong river water quality based on its physical and chemical parameters. This research was conducted from November to December 2019 with sampling locations in the Semuong River and analysis done at the Environmental Laboratory of PT. Unilab Perdana. Water sampling was carried out at five stations, namely left, right, main, upstream and downstream Lunik. The results of the measurement of samples were compared with the quality standards stipulated by Lampung Regional Regulation No. 11 of 2012 and analyzed using the STORET method. The results showed that The values of several parameters were exceeded the threshold for class III water quality standards, namely BOD and COD. Based on STORET index in the first sampling has a total score of -4 which is categorized as lightly polluted, the second sampling has a total score of -16 which is categorized as moderate pollution, the third sampling has a total score of -40 which is categorized as heavily polluted, and the forth sampling has a score of 0 which is categorized as not polluted

Abstract

Ketapang Beach, situated in Pesawaran Regency, Lampung, is a well-known tourist spot frequented by many visitors. The beach features a pier and a boat lane used for transporting tourists to nearby islands. Additionally, the surrounding area is home to residential communities and small-scale fish farming. Despite this activity, a comprehensive analysis of the beach’s water conditions had not been conducted previously, and there is limited information available on its water quality and pollution levels. Given the extensive human activity, it is crucial to monitor the water quality regularly, as these activities can significantly impact the ecosystem. This study collected data on several physical, chemical, and biological water parameters, such as temperature, total suspended solids (TSS), pH, salinity, dissolved oxygen, biochemical oxygen demand (BOD5), ammonia, nitrite, orthophosphate, lead (Pb), and total coliform bacteria. These parameters were measured to evaluate the water quality using the Pollution Index (IP), with reference to the seawater quality standards for marine tourism and aquatic life. The findings revealed that several parameters—such as salinity, dissolved oxygen, BOD5, ammonia, orthophosphate, and lead (Pb)—exceeded the recommended thresholds. Based on the Pollution Index assessment, the waters at Ketapang Beach were classified as moderately polluted.Keywords: Ammonia, pollution index, purposive sampling, water pollution.

Abstract

Penelitian ini bertujuan untuk menganalisis berbagai aspek biologi ikan gabus, termasuk tingkat kematangan gonad, indeks kematangan gonad, ukuran pertama kali matang gonad, fekunditas, dan pola pemijahan, serta faktor-faktor yang memengaruhi kematangan gonad dan pemijahan di berbagai daerah melalui studi literatur. Penelitian ini mencakup 16 jurnal yang diterbitkan dalam 10 tahun terakhir. Hasil analisis menunjukkan bahwa tingkat kematangan gonad dan indeks kematangan gonad ikan gabus (Channa striata) dipengaruhi oleh berbagai faktor lingkungan dan biologis. Terdapat variasi signifikan dalam kematangan gonad ikan gabus yang berkaitan erat dengan habitat dan kualitas perairan. Indeks kematangan gonad dipengaruhi oleh musim pemijahan dan ketersediaan makanan, menunjukkan bahwa pola pemijahan ikan gabus bisa bersifat parsial atau total spawner. Sebagian besar daerah penelitian menunjukkan pola pemijahan partial spawner, yang ditandai dengan distribusi diameter telur yang memiliki lebih dari satu modus, menandakan pemijahan bertahap. Namun, pola pemijahan total spawner ditemukan di beberapa lokasi, dipengaruhi oleh perbedaan waktu penangkapan dan musim. Variasi ukuran pertama kali matang gonad di berbagai lokasi disebabkan oleh perbedaan dalam habitat, musim pemijahan, jenis kelamin, ketersediaan makanan, dan kualitas perairan. Selain itu, variasi fekunditas ikan gabus dapat dipengaruhi oleh ukuran ikan, kondisi lingkungan, dan faktor genetik.

Abstract

Keberhasilan dalam budidaya ikan lele sangat bergantung pada pemilihan bibit yang berkualitas serta proses aklimatisasi yang tepat. Kegiatan pengabdian masyarakat ini bertujuan untuk meningkatkan pengetahuan dan pemahaman pembudidaya ikan mengenai cara memilih bibit lele yang baik dan teknik aklimatisasi yang tepat. Pelaksanaan kegiatan ini melibatkan pelatihan langsung, penyuluhan, dan demonstrasi di lapangan. Metode yang digunakan meliputi pembelajaran teori, praktik lapangan, dan diskusi interaktif. Hasil dari kegiatan ini menunjukkan peningkatan signifikan dalam pengetahuan dan keterampilan peserta dimana peserta memahami tentang karakteristik bibit lele yang berkualitas sebesar 87,5% dan teknik aklimatisasi yang benar 81,25%. Kelompok pembudidaya dapat membedakan benih ikan lele yang baik dan sehat serta dapat melakukan proses aklimatisasi ikan yang tepat sehingga nantinya akan dijadikan referensi pengetahuan untuk kegiatan budidaya ikan. Keberhasilan kegiatan ini diharapkan dapat berkontribusi pada pengembangan budidaya ikan yang lebih berkelanjutan dan produktif.

Abstract

Tirtayasa Beach is a coastal tourism attraction in Bandar Lampung City, located in Way Tataan Village, East Teluk Betung District. The waters of Tirtayasa Beach have significant tourism potential due to their natural beauty. However, a decline in water quality, caused by increased human activities and domestic waste input around the beach, has affected the physical, chemical, and biological conditions of the waters. Mollusks can serve as indicators of water quality. Therefore, the structure of the mollusk community can be used to assess the condition of these waters. This study aimed to evaluate the structure of mollusk populations and analyze the influence of water quality on mollusk communities in the intertidal zone of Tirtayasa Beach, East Teluk Betung District, Lampung. The selection of study locations/stations and observation points was carried out using the purposive sampling method. The mollusks identified in the waters of Tirtayasa Beach belong to two classes: Gastropoda and Bivalvia. The Gastropoda class, with eight species, dominated across the three stations, with Cerithium kobelti being the most prevalent species. The parameter that significantly affected mollusk abundance at Station 1 was pH. At Station 2, depth, brightness, dissolved oxygen (DO), and salinity were influential. At Station 3, total suspended solids (TSS) and temperature were the key influencing factors.  Keywords: Abundance, biodiversity, evenness index, principal component analysis.

Abstract

Yellowstripe scad (Selaroides leptolepis) is a type of pelagic fish that is dominantly caught in the waters of Lampung Bay and is landed at the Lempasing Coastal Fisheries Harbor. The high market demand for yellowstripe scad means fishing for this fish is carried out throughout the year. The aim of this research was to analyze the population dynamics of yellow trevally (Selaroides leptolepis) in the waters of Lampung Bay. The yellow trevally fish collected during the research came from fishermen's catches in the waters around Lampung Bay. The study's findings demonstrated that the yellow trevally's development pattern was negative allometric, and its condition factor value varied between 0.7509 and 1.0842.  the growth parameters of yellowstripe scad obtained an asymptotic length (L∞) value of 152 mm, the growth coefficient (K) of 0.57/year, and theoretical age (t0) of -0.2191 years. Yellow trevally have a natural mortality value (M) of 0.80 per year, a fishing mortality value (F) of 1.12 per year, and a total mortality value (Z) of 1.92/year. Yellowstripe scad recruitment peaked in the Sunda Strait between May and September, at 18.19% and 13.90%, respectively.
