Abstract

Dampar Beach is one of the area in Lumajang which has abundant fisheries resources and lobster is one of export commodities. Nowadays, increased trade and local market demand led to an increase in lobster sales and will lead to a decrease in lobster stocks. Therefore, a sustainability analysis is needed in managing these fishery resources. This study aims to determine the level of sustainability of lobster fisheries in Dampar Beach, Lumajang in four dimensions, i.e. economic, social, ecological, and technological dimension. The sustainable management strategy of lobster fisheries also determined and discussed. The research method for the analysis of sustainability status uses RAPFISH (Rapid Appraisal for Fisheries Sustainability). This type of research uses a descriptive method with a quantitative approach. The results showed that the sustainability index value of the economic and technology dimension are 39.29% and 48.79%, respectively (less sustainable). The social and ecological dimension are 60.44% and 50.72%, respectively (enough sustainable). The strategies for lobster fisheries at Dampar Beach, Lumajang should focus more on attributes that have high leverage, especially on the social, economy, and ecology dimensions. The utilization of lobster resources in a sustainable manner is basically the goal of management which guarantees the level of resource utilization that does not damage or exceed its recovery capacity, so that it can serving the living needs of present and future generations.

Abstract

Infection is a health problem that can cause death in the world. An antibiotics is a treatment used to treat infectious diseases. If antibiotics are used continuously, they can cause resistance. One of the bacteria that causes skin infections and has been reported to be resistant to several antibacterials is Staphylococcus aureus. So we need an alternative to exploring antibacterial compounds derived from the ocean. Sponge extract from the genus Agelas has been reported to contain secondary metabolites that are antibacterial. This research aims to determine the antibacterial potential of sponge extract and the secondary metabolite of sponge extract, Agelas cervicornis. The extraction process uses maceration with methanol as a solvent. The tests carried out in this study included a phytochemical screening test and an antibacterial activity test carried out using the disc diffusion method to determine the inhibition zone produced against the pathogenic bacteria Staphylococcus aureus. The results of phytochemical screening showed that the sponge extract of Agelas cervicornis contained flavonoids, alkaloids, and terpenoids. The results of the antibacterial activity test of the sponge extract of Agelas cervicornis showed that all concentrations of 0.5 mg/ml, 1 mg/ml, and 1.5 mg/ml had weak inhibitory properties.

Abstract

Linear Alkylbenzene Sulfonate (LAS) is a type of anionic surfactant which is commonly used as a raw material in making commercial detergents or cleaners. Even though LAS can be degraded naturally in the environment, detergent wastewater containing LAS still needs to be treated properly before being discharged into the environment. One way that can be done to reduce the toxic effects of LAS is biodegradation. The use of bacteria, especially endophytic bacteria associated with plants, is known to have potential as a biodegradation agent for LAS. This review aims to examine the potential of endophytic bacteria as LAS biodegradation agents. The method used in this review is a literature review from several international and national journal references. Data were analyzed descriptively and presented in narrative and table form. The results of the research show that several species of endophytic bacteria isolated from various types of plants have the potential to degrade pollutants, such as heavy metals, benzene, phenol, phenanthrene (PHE), diesel, ammonium, phosphate, COD, and hydrocarbons which also shows that endophytic bacteria have the potential to degrades LAS.

Abstract

Tradisi petik laut sering juga disebut dengan larung sesaji yang dikaitkan dengan syukuran para nelayan atas segala hal yang telah diberikan oleh laut. Saat ini petik laut telah mengalami transformasi menjadi ajang pesta rakyat, namun sejatinya ritual petik laut ini merupakan ekspresi spiritualitas komunitas nelayan pesisir di Jawa dan Madura. Untuk menjaga salah satu kearifan lokal tersebut maka perlu dilakukan kajian yang komprehensif mengenai tradisi petik laut dalam tinjauan sains dan Islam. Secara spesifik, penelitian ini bertujuan untuk mengetahui pengaruh bacaan Al-Quran pada pertumbuhan mikroorganisme atau bakteri air laut. Hal ini dikarenakan mikroorganisme atau bakteri merupakan salah satu aktor yang berperan penting dalam sistem kelautan yang selanjutnya akan mempengaruhi produktivitas perairan dan hasil tangkap. Pengambilan sampel air laut yang digunakan dalam penelitian ini adalah air laut di pesisir Sidoarjo. Sampel diambil pada permukaan air laut sejauh 100 meter dari bibir pantai dan dilakukan sekali untuk semua sampel. Analisa pertumbuhan mikroorganisme air laut dilakukan di laboratorium mikrobiologi. Perlakuan yang diberikan adalah dibacakan (1) surat an-Nahl, (2) al-Fatihah, dan (3) tanpa perlakuan (kontrol). Sampel pengontrol (pre-test/baseline) dan sesudah perlakuan (post test) ditumbuhkan dalam media NA dengan teknik Total Plate Count (TPC) di laboratorium. Penghitungan jumlah bakteri dengan menggunakan colony counter dilakukan setelah diinkubasi selama 24 jam. Data hasil pengamatan jumlah koloni bakteri akan diuji dengan dengan menggunakan dua variabel yaitu perlakuan dan hari. Hasil analisa statistik dengan menggunakan analisis non-parametrik uji Friedman menunjukkan bahwa besaran nilai Chi Square = 30.545 dan asymp sig sebesar 0.000. Hasil tersebut menunjukkan bahwa ketiga perlakuan (dibacakan surat an-Nahl, al-Fatihah dan tanpa perlakuan (kontrol)) memberikan reaksi yang berbeda dengan jumlah nilai TPC atau pertambahan koloni bakteri air laut.
