Full text linkSungai Somber merupakan salah satu sungai yang memiliki ekosistem mangrove di kota Balikpapan. Tingginya aktivitas manusia di kawasan sungai Somber dapat menghasilkan limbah dan pencemaran logam berat di ekosistem mangrove, terutama di sedimen. Tujuan dari penelitian ini adalah untuk menentukan konsentrasi Fe, Mn dan Zn pada sedimen mangrove. Selain itu, nilai indeks pencemaran seperti tingkat kontaminasi (TK), indeks beban pencemaran (IBP) dan indeks geoakumulasi (I-Geo) pada sedimen juga ditentukan di sepanjang sungai Somber, kota Balikpapan. Metode penelitian yang dilakukan di penelitian ini adalah purposive sampling. Sampel sedimen diambil dari 9 titik sampling di sepanjang sungai Somber. Sampel sedimen didestruksi menggunakan zat asam dan dianalisis menggunakan Atomic Absorption Spectrophotometer (AAS) Aurora AI 1200 untuk menentukan konsentrasi Fe, Mn, dan Zn berdasarkan berat kering (dry weight) dalam µg/g. Berdasarkan hasil analisis, ditemukan bahwa konsentrasi Fe pada sedimen mulai dari 5403 sampai 12268 µg/g dengan rerata 9462 ± 2294 µg/g. Pada Mn, nilai konsentrasinya antara 2,25 - 23,2 µg/g dengan rerata 11,4 ± 7,43 µg/g. Kemudian, konsentrasi Zn antara 16,6 - 61,3 µg/g, dengan rerata 43,4 ± 17,4 µg/g. Bervariasinya konsentrasi Fe, Mn dan Zn mungkin ada kaitannya dengan beberapa aktifitas manusia seperti kegiatan industri, dok kapal, pemukiman penduduk, perikanan, pelabuhan serta distribusi logam dari sungai Somber. Konsentrasi Mn dan Fe di semua stasiun penelitian lebih rendah dari standar baku mutu sedimen, kecuali Fe. Tingkat kontaminasi Fe, Mn dan Zn pada sedimen masih rendah (TK<1) dan tidak tercemar (IBP<1) dan indeks geoakumulasi (I-geo) termasuk tidak tercemar hingga tercemar (0<I-geo<1).Somber River is one of the rivers with mangrove ecosystem in Balikpapan city. The high human activity in Somber River area may produce waste and heavy metal pollution in mangrove ecosystem, especially in sediment. The purpose of this study is to determine the concentration of Fe, Mn and Zn in mangrove sediments. In addition, the values of pollution indices such as contamination level (TK), pollution load index (IBP) and geoaccumulation index (I-Geo) in sediments are also determined along Somber river, Balikpapan city. The research method used in this study is purposive sampling. Sediment samples were taken from 9 sampling points along Somber river. Sediment samples were deconstructed using acid and analyzed using the Atomic Absorption Spectrophotometer (AAS) Aurora AI 1200 to determine the concentration of Fe, Mn, and Zn based on dry weight in µg/g. Based on the analysis, it was found that the Fe concentration in the sediment ranged from 5403 to 12268 µg/g with an average of 9462 ± 2294 µg/g. In Mn, the concentration value was between 2,25 and 23,2 µg/g with an average of 11,4 ± 7,43 µg/g. Then, the Zn concentration was between 16,6 and 61,3 µg/g, with an average of 43,4 ± 17,4 µg/g. The varying concentrations of Fe, Mn and Zn might be related to several human activities, such as industrial activities, boat docks, settlements, fisheries, ports and metal distribution from the Somber river. The concentrations of Mn and Fe at all research stations were lower than the sediment quality standards, except for Fe. The level of Fe, Mn and Zn contamination in sediments was low (TK<1) and not polluted (IBP<1) and the geoaccumulation index (I-geo) was not polluted to polluted (0<I-geo<1)
RESPONSE OF EELS (Monopterus sp) TO VARIOUS TYPE OF FEED
Full text linkEel seeds for aquaculture are primarily sourced from the wild. These seeds respond poorly to feed during the initial rearing phase. Therefore, this study aimed to provide feed that eels can consume in the early stages of culture. This study used an experimental method by testing the level of eel acceptance for natural feed, namely worms (Lumbricus sp.), golden snails (Pomacea sp.), chicken intestines, and maggots (black soldier flies), which will then be used as attractants mixed with pellet flour. Based on the order of feed selection and the time duration of eel response to the feed, eels preferred earthworms and snails as feed compared to maggots and chicken intestines. However, the four tested feed types can be consumed by eels. Mixing earthworms with pellet meal in the form of paste feed was responded well by eels. Eels consumed more (p <0.05) pellet meal mixed with earthworms than feed that did not have earthworms added to it. The incorporation of earthworms as an attractant in paste feed, as much as 50%, produced the same eel growth (P> 0.05) as eels given 100% worms. It indicated that a combination of artificial feed and earthworms could facilitate the consumption of artificial feed by eels in the initial phases of culture.Benih belut kebanyakan diambil dari alam. Belut hasil tangkapan yang digunakan sebagai benih sangat lambat untuk merespon pemberian pakan pada saat awal penebaran. Oleh karena itu penelitian ini bertujuan untuk menyediakan pakan yang dapat dikonsumsi oleh belut dimasa awal pemeliharaan. Penelitian ini menggunakan metode experimental dengan menguji tingkat penerimaan belut terhadap pakan alami yaitu cacing (Lumbricus sp.), keong mas (Pomacea sp.), usus ayam, dan maggot (black soldier fly) yang selanjutnya akan digunakan sebagai atraktan yang dicampur pada tepung pellet. Berdasarkan urutan pemilihan pakan dan lama waktu belut merespon pakan, maka cacing dan keong lebih dipilih oleh belut sebagai pakan dibandingkan dengan magot dan usus. Meskipun demikian keempat jenis pakan yang dicobakan dapat dikonsumsi oleh belut. Pencampuran cacing pada tepung pellet dalam bentuk pakan pasta direspon dengan baik oleh belut. Belut akan lebih banyak (p<0,05) mengkonsumsi tepung pellet yang dicampur dengan cacing dibandingkan dengan pakan tanpa penambahan cacing. Pencampuran cacing sebagai atraktan dalam pakan pasta sebanyak 50% menghasilkan pertumbuhan belut yang sama (P>0,05) dengan belut yang diberikan cacing 100%. Hal ini menujukkan pakan buatan yang dicampur dengan cacing dapat digunakan untuk menginisiasi pengambilan pakan buatan oleh belut selama masa awal pemeliharaan

INTEGRATING SWOT AND AHP IN A PARTICIPATORY STRATEGY FOR DISSEMINATING FISHERIES PRODUCTIVITY INFORMATION IN SEGARA ANAKAN LAGOON, CILACAP REGENCY
Full text linkThe Segara Anakan Lagoon (LSA) is a coastal region characterized by unique ecological features and a high level of biodiversity in its fishery resources. Functioning as the estuarine outlet of the Citanduy River Basin, the lagoon receives substantial freshwater inflow laden with high sediment loads. This natural dynamic, compounded by anthropogenic activities from surrounding communities, has led to ecological degradation manifested in declining water quality, reduction of the lagoon’s water body, and increased nutrient accumulation, which in turn triggers eutrophication. Consequently, the fishery resource potential has diminished, adversely affecting the welfare of local fishing communities, as evidenced by a growing trend of occupational shifts from fishing to farming. This community engagement study, grounded in scientific research, aims to mitigate the rate of ecological degradation while promoting behavioral transformation toward a conservation-oriented mindset as a strategic measure to enhance the livelihoods of fishers. The methodology encompasses the development of thematic maps based on in situ ecological analyses, a SWOT (Strengths, Weaknesses, Opportunities, Threats) analysis to identify the strategic conditions of the LSA area, and the application of the Analytical Hierarchy Process (AHP) to establish solution prioritization. All quantitative data obtained were disseminated to the local community through Focus Group Discussions (FGDs). Community perception and participation were evaluated using structured questionnaires, with subsequent statistical analysis performed to test the validity and reliability of the instruments. Through this participatory approach, it is anticipated that information on high-potential fishery zones and viable ecological management solutions can be effectively communicated, thereby enhancing the adaptive capacity of coastal communities for sustainable resource governance.The Segara Anakan Lagoon (LSA) is a coastal region characterized by unique ecological features and a high level of biodiversity in its fishery resources.
