Abstract

Sampah menjadi salah satu permasalah umum yang menarik banyak perhatian dari seluruh kalangan karena hingga saat ini masih menjadi permasalahan yang belum dapat ditangani secara baik bahkan menjadi potensi bencana yaitu bencana darurat sampah. Sebagai Langkah mitigasi bencana darurat sampah dapat dilakukan dengan penanganan sampah. penanganan sampah adalah rangkaian kegiatan mencakup pemilahan-pemisahan sampah menurut jenis dan sifatnya, pengumpulan sampah, pengakutan sampah dan pengolahan hasil akhir. Satu bentuk pengolahan hasil akhir untuk sampah rumah tangga adalah dengan mengubah sampah organik rumah tangga menjadi kompos. Kegiatan dilakukan dengan metode ceramah dan diskusi kepada masyarakat Pesisiri Bumi Waras. Kegiatan pengelolaan sampah rumah tangga dengan mengolah sebagai pupuk kompos, dapat diterima oleh masyarakat sebagai salah satu solusi upaya pengurangan penumpukan sampah di wilayah Pesisir Bumi Waras, dan juga dapat sebagai sarana usaha penjualan pupuk untuk menambah penghasilan masyarakat.

Abstract

Caulerpa sp. (anggur laut) adalah jenis rumput laut hijau yang tumbuh di perairan tropis dan subtropis. Pengobatan jerawat umumnya menggunakan antibiotik, tetapi dapat menyebabkan efek samping dan resistensi bakteri. Penelitian ini bertujuan untuk mengeksplorasi potensi Caulerpa sp. sebagai alternatif pengobatan jerawat alami. Dilaksanakan di Laboratorium Oseanografi Universitas Lampung dari Oktober hingga November 2024, penelitian ini menggunakan metode maserasi dengan metanol 95% untuk ekstraksi. Aktivitas antibakteri diuji terhadap Propionibacterium acnes dengan metode difusi cakram. Hasil menunjukkan bahwa ekstrak metanol Caulerpa sp. memiliki aktivitas antibakteri yang lemah, dengan zona hambat tertinggi 4,03 mm pada konsentrasi 10.000 ppm. Beberapa faktor yang mempengaruhi aktivitas ini termasuk konsentrasi senyawa bioaktif dan karakteristik resistensi bakteri. Penelitian lebih lanjut diperlukan untuk meningkatkan efektivitas ekstrak ini sebagai agen antibakteri alami.

Abstract

Graphical Abstract   Highlight Research 1. Sargassum polycystum has been extracted and analyzed. 2. Cytobacillus kochii GSD in response to fucoidanase-producing enzyme activity was analyzed. 3. Optimum temperature, pH, and salinity can suppress the activity of the fucoidanase enzyme through the inhibition test. 4. Cytobacillus kochii GSD can produce fucoidanase enzyme with low molecular weight.     Abstract Extensive research has shown that low molecular weight fucoidan exhibits significantly greater biological activity than its high molecular weight. C. kochi GSD, a Sargassum symbiont bacterium, is proven to have the activity of hydrolyze fucoidan. This study proposes the growth optimization and fucoidanase enzymatic activity of C. kochii GSD bacteria under varying environmental conditions (temperature, pH, and salinity) cultured in basic liquid medium (BLM) for 48 hours. Based on Response Surface Methodology (RSM), the range of temperature, pH, and salinity for the growth optimization test of C. kochi GSD bacteria were 26.591, 30, 35, 40, and 43.49oC, the pH used starts from 3.636, 5, 7, 9, and 10.363, while the salinity to be used starts from 3.522, 5, 17.5, 30, and 38.522 ppt, respectively. The best conditions for growth of each environment were then continued with the test of fucoidanase enzyme activity in vitro. The results showed that C. kochii GSD bacteria grew optimally at temperature, pH, and salinity of 35oC, 7, and 30 ppt, respectively. The optimum enzyme activity of C. kochii GSD is at 72 hours with the forming of clear zones on media containing fucoidan and given Cetylpyridinium chloride (CPC) solution with clear zone diameters of 31.17 mm (temperature), 25.9 mm (pH), and 20.97 mm (salinity), respectively. The conclusion of this study is a high novelty finding to produce low molecular weight fucoidan enzymatically with C. kochii GSD bacteria to be used as an immunostimulant.

Abstract

The waters of Lampung Bay have high potential resources for threadfin bream (Nemipterus sp.). This fish has significant economic value as a diverse food ingredient. However, currently, the body size of threadfin bream found tends to be uniform and even smaller due to continuous overfishing. The research was conducted to assess the status of utilization of threadfin bream resources in the waters of Lampung Bay based on five important aspects, namely ecology, economics, social, technological and institutional. The research was carried out in May 2023 at Lempasing Fishing Port, Bandar Lampung City, with data collection through observation and interviews. Data analysis used the multi-dimensional scaling (MDS) method using the Rapfish (rapid appraisal for fisheries) application to evaluate the sustainability of the use of threadfin bream. The results of the analysis show that the sustainability index value for the use of threadfin bream in the waters of Lampung Bay is as follows: ecological dimension 48.59; economic dimension 36.80; social dimension 75.00; technology dimension 49.91; and ethical dimension 61.64. Based on these results, it can be concluded that the use of threadfin bream in the waters of Lampung Bay is quite sustainable, with an average index value of 54.39.Keywords: Ecological dimension, multi-dimensional scaling, Rapfish, sustainability index.
