Abstract

Earthquake and tsunami struck Palu bay on September 28, 2018, and has affected the entire coast. BCF habitat on Palu bay was lost by the tsunami. BCF depends on its habitat for survival. Banggai cardinalfish is a paternal mouthbrooder with direct development, without pelagic phase and sedentary movement. If habitat extinction occurs, there is a small chance for the population to recover naturally. The BCF spread was naturally uneven, although on a relatively uniform habitat. This research aimed at determining BCF biodiversity in the Gulf of Palu and examined the distribution of BCF in Palu bay. The Determination of BCF population was done by visual census through Fish Belt Transect method and Swim Survey method, besides the conditions and habitat composition were done by using Point Intercept Transect (PIT) method. Surveys were carried out by2 times observations with 5 meters width and the transect length in a repeat was 25 meters. The results obtained the living habitat of P. kauderni on both observation locations consist of hard corals, anemones, and sea urchins. The diversity index obtained indicated that the diversity and community stability were low, while uniformity index indicated that the distribution between individual types of reasonably uniform. In contrast, the dominance index showed that the size of the adults was more dominating on the habitat on both of the observation locations. These findings would be a reference for habitat restoration of Banggai cardinalfish (BCF) post-disaster.

Abstract

Gelatin is derivative protein of collagen fiber which is found in the skin, bone, and cartilage. The composition of amino acids is almost similar to collagen, where glycine as the main amino acid and as 2/3 of all the amino acids that make it up, where 1/3 of the amino acids contained by proline and proline hydroxine. This research aims at knowing the physical charateristic of rendement and pH by using the skin of tilapia (Oreochromis niloticus) in concentration of HCL as immersion solution. The benefits of this research are expected to be the information sources of gelatin making in production scale, especially the gelatin production from the skin of tilapia (Oreochromis niloticus). The information are expected to support the development of information science and technology (IPTEK). Gelatin of tilapia skin (Oreochromis niloticus) used Completely Randomized Design (RAL) with 4 treatments. The treatments were HCl immersion to Tilapia’s skin (Oreochromis nilaticus) with N1 (4%), N2 (5%), N3 (6%) and N4 (7%) in 4 times repetitions

Abstract

Marine debris provides habitat for several species. These species attach and carried (rafting) marine debris in all directions following the ocean currents. When stranded, these alien species will quickly develop because they have high survival and adaptation capabilities, these alien species will cause economic, ecological and social impacts. This research begins with a survey of the presence of marine debris that attached by alien species on coast of Palu Bay, then observations on the marine debris such as: size, weight, observations on alien species such as: type, size, colony size, ability to spread and survive, impact category based on literature. The aim of this study was to identify the types of alien species carried by marine debris in Palu Bay.  Calculating the amount of alien species carried by marine debris in Palu Bay. Based on the analysis, there are 3 alien species on the coast of Palu Bay. Lepas sp were 247 individuals, then Isognomon sp with 124 individuals and Saccostrea cuccullata d for 36 individuals. The species were found on wood, iron, coconut, PVC pipes, bamboo, nets and boat ropes as substrates.

Abstract

Coral reefs are very important ecosystems and have a direct economic impact on coastal communities. In addition, coral reef ecosystems also play a role in providing habitat for various kinds of marine organisms such as Echinoderms, Crustaceans, Polychaeta, Chordata, Molluscs, Annelids and free-living marine biota such as plankton and fish. Over-exploitation of coral reefs and their resources, changes in top land that cause sedimentation and other anthropogenic activities will cause damage to coral reefs. Increasing pressure can threaten the existence and sustainability of coral reef ecosystems and the biota that live in them. In 2018 there was an earthquake 7.4 Richter scale accompanied by tsunami, the impact was large of destruction of the aquatic biota habitat of coral reef ecosystem. The aims of this study were (1) to examine the condition of coral reefs in Palu Bay, (2) to examine the composition of coral reefs in Palu Bay. Coral reef data was collected using the Line Intercept Transect (LIT) method. For coral reef observations using a transect with a length of 25 m, with  every 50 cm observations or 50 points/transect. Each location were carried out 2 times. The results obtained shown the growth conditions of live coral were poor, but coral growth has started to improve. For water quality, it shown that the water quality in Palu Bay was suitable for coral reefs growth.

Abstract

Akumulasi cemaran mikroplastik di Teluk Palu berpotensi masuk ke rantai makanan. Penelitian ini bertujuan untuk mengkaji konsentrasi dan identifikasi mikroplastik di permukaan air, kolom air dan sedimen di pesisir Teluk Palu. Penelitian dilakukan pada bulan Agustus hingga Oktober 2022. Pengambilan sampel mikroplastik dilakukan pada 5 titik pengambilan sampel dengan pengulangan sebanyak 3 kali. Sampel mikroplastik yang dianalisis menggunakan metode perendaman dengan larutan KOH 10% dan H2O2 30% selama 4 hingga 10 hari dan untuk memastikan bahwa objek yang dianalisa adalah mikroplastik dilakukan metode Hot Needle Test. Mikroplastik jenis serpihan yang paling tinggi ditemukan. Titik pengamatan station 3, Lere, kepadatan mikroplastik tertinggi yaitu: permukaan air 11.29 partikel/l; kolom air 1.14 partikel/l; dan sedimen 62.08 partikel/kg. Penelitian ini menunjukkan bahwa input dari Sungai Palu sangat mempengaruhi kepadatan mikroplastik di Teluk Palu.Kata Kunci: mikroplastik, kolom air, permukaan, polusi, sedimen, Teluk Palu
