Abstract

The Jagir River estuary system constitutes a significant ecosystem in Surabaya that sustains the livelihoods of the surrounding communities. Despite its importance, the river is subjected to substantial pollution originating from domestic and industrial waste. Therefore, this study aims to investigate the patterns of physicochemical interactions between lead (Pb) in the Jagir River estuary system. Water and sediment samples were collected at 5 strategic points, and the concentration of Pb was analyzed using Inductively Coupled Plasma optical emission spectrometry (ICP-OES). The correlation between Pb and various environmental parameters (temperature, salinity, DO, pH & TDS) was analyzed using Principal Component Analysis (PCA). The results showed that the concentrations of Pb in the water column and sediment were 0.1637 – 1.8905 ppm and 0.0735 – 0.2349 ppm, respectively, exceeding the established quality standards for water. Pb content in the waterbody exhibited an increasing trend from upstream to the sea. These results show the salinity and tidal parameters as characteristic features of the Jagir River estuary system, which influence Pb content in water and sediment. The distinct characteristics of this estuary system vary for each region or location, showing that the results can contribute to the development of environmental policies and monitoring of water quality.Received: 2024-08-15 Revised: 2024-09-12 Accepted: 2025-01-25 Published: 2025-04-28

Abstract

Cancer is one of the leading causes of death in the world. The main therapies for cancer include surgery, chemotherapy, radiotherapy. However, the use of chemotherapy drugs can cause side effects such as hair loss, bone marrow suppression, drug resistance. Based on these side effects, this study conducted research on natural ingredients as an alternative to cancer treatment. Rhizophora mucronata can be used as an anticancer, where people in coastal areas or around mangrove forests use mangroves as medicinal plants, and are believed to have minimal side effects so that they can be developed as traditional medicines. In this study, analysis of phytochemical screening and anticancer potential tests of methanol extract of Rhizophora mucronata stem bark was carried out from Pamurbaya, Surabaya, East Java. In this study, the BSLT (Brine Shrimp Lethality Test) method was used to test the anticancer potential with the LC50 (Letal Concentration) value as a parameter. The results of phytochemical screening of the methanol extract of Rhizophora mucronata stem bark contain tannins, saponins, alkaloids, steroids, flavonoids, anthraquinones and polyphenols and have anticancer potential with an LC50 value of 120.8656 ppm which falls into the toxic category.

Abstract

Indonesia is a country that has a variety of marine ecosystems that have a lot of potential, one of which is mangroves. Rhizophora mucronata is a species in the mangrove ecosystem in Indonesia. Rhizophora mucronata or black mangroves are plants that contain various kinds of compounds. Antioxidants play an important role in the prevention of degenerative diseases. This research is motivated by the presence of carcinogenic dangers caused by consuming synthetic antioxidants at high doses synthetic antioxidants can function as prooxidants which can increase oxidative stress and damage body cells, so it wants to explore the natural antioxidant potential of Rhizophora mucronata. Rhizophora mucronata root was chosen in this study because no one has examined the potential of this plant that grows in the Pamurbaya area, Surabaya - East Java as an antioxidant. This study aims to determine the content of secondary metabolites and antioxidant activity of the root extract of Rhizophora mucronata. In this study, the antioxidant activity test used the DPPH (2,2-diphenyl-1-picrylhydrazyl) method. The results showed that the antioxidant activity of the methanol extract of Rhizophora mucronata root had very weak antioxidant activity with an IC50 value of 2604.56 ppm. The antioxidant potential of the methanol extract of Rhizophora mucronata root has an IC value of 50 with a very weak antioxidant intensity

Abstract

Free radicals are compounds that trigger oxidative stress and harm human health. Uncontrolled oxidative stress causes several degenerative diseases. Antioxidants are needed to prevent or reduce oxidative stress. One of the plants with a high content of antioxidant compounds is brown algae (Sargassum sp). The study aimed to examine Sargassum sp.'s antioxidant activity, which is expressed in the IC50 value using the DPPH method as measured by a UV-Vis spectrophotometer. It is a narrative review, with literature searches from the Science Direct, Pubmed, and Google Scholar databases. The results showed that the methanol extract of Sargassum sp. has strong antioxidant activity consisting of phenolic compounds, flavonoids, and carotenoids. This review concludes that Sargassum sp extract has antioxidant activity.

Abstract

Sungai Gunung Anyar Surabaya digunakan untuk pembuangan limbah rumah tangga karena terdapat pemukiman padat penduduk di sepanjang alirannya. Selain itu, terdapat tambak-tambak yang membuang sisa pakan dan sisa metabolisme ke Sungai Gunung Anyar. Limbah yang mengandung unsur hara seperti nitrat dan fosfat akan dimanfaatkan oleh fitoplankton untuk pertumbuhannya. Masuknya bahan organik nitrat dan fosfat, ke muara dapat mempengaruhi kualitas air yang berpengaruh pada keberadaan fitoplankton. Tujuan penelitian ini adalah menganalisis hubungan konsentrasi nitrat dan fosfat terhadap kelimpahan fitoplankton di Perairan Mangrove Gunung Anyar, Surabaya. Penelitian ini dilakukan pada pertengahan bulan Oktober sampai Desember 2021. Pengambilan sampel dilakukan pada sembilan stasiun dengan metode pengambilan fitoplankton secara horizontal. Analisis fitoplankton menggunakan Sedgwick Rafter Counter Cell (SRCC). Sampel air digunakan untuk menganalisis nitrat dan fosfat yang selanjutnya dianalisis menggunakan Spektrofotometri Uv-Vis. Analisa data meliputi densitas absolut fitoplankton, indeks keanekaragaman fitoplankton, serta uji regresi untuk mengetahui hubungan nitrat dan fosfat dengan fitoplankton. Konsentrasi nitrat tergolong oligotrofik sedangkan konsentrasi fosfat tergolong mesotrofik. Kelimpahan fitoplankton termasuk dalam kategori oligotrofik. Indeks keanekaragaman (H’) termasuk dalam kategori sedang. Hubungan antara nitrat terhadap kelimpahan fitoplankton menunjukkan (r) memiliki korelasi lemah, sedangkan hubungan antara fosfat terhadap kelimpahan fitoplankton menunjukkan (r) memiliki korelasi cukup.

Untuk validitas data digunakan yakni melalui uji kreadibilitas data dengan cara triangulasi sumber dan triangulasi teknik. Hasil penelitian ini menunjukkan bahwa di era sekarang ini dakwah dilakukan dengan berbagai metode dan menyesuaikan dengan situasi saat ini. Sehingga ajaran-ajaran Islam dapat diterima oleh mad’u. maraknya wisata di Lombok nusa tenggara barat yang dapat memberikan nutrisi ajaran-ajaran Islam dimana Lombok dijuluki dengan pulau seribu masjid. Abstract:This study aims to provide communities an understanding about the importance of spreading the Islamic teachings through tourism sites. Given tourism is currently growing rapidly in Indonesia, especially in Lombok, West Nusa Tenggara, this allows Islamic teachings can be accepted by both foreign and domestic tourists. The data were collected through triangulation which was the combination of data collection techniques and existing data sources. The data were analyzed through interactive analysis consisting of four stages; data collection, data reduction, data presentation, and conclusions drawing. Validity of the data was done through data credibility test by means of triangulation of sources and techniques. The results of this study indicated that in the current era, da'wah is carried out through various methods and adapted to the current situation so that Islamic teachings can be accepted by mad'u. Also, the rise of Lombok tourism, well known as the island of a thousand mosques, has provided chances for teaching Islamic values.
