Abstract

Chlorella sp. is a single-celled microalga that mostly grows in marine waters. Chlorella sp. can grow in heavy polluted waters and therefore it has potency as a bioremediation agent. This study aimed was to analyze the effect of coal on the growth of Chlorella sp. in plant isolation media and the quality of water in plant isolation media for Chlorella sp. The complete randomized design with 4 treatments of coal concentration was used in this study. Four concentration concentrations were tested namely, 0 ppt, 1 ppt, 3 ppt and 5 ppt. The results revealed that coal with different concentrations gave no significant effect on the growth of Chlorella sp. (p 0.05). The density among the concentrations of 0 ppt, 1 ppt, 3 ppt and 5 ppt were not significantly different. In addition, the coal concentration gave no significant effect on temperature, salinity and potential hydrogen (pH) (p0.05). The Chlorella sp. can grow in the polluted water by coal, and therefore this alga can be used as potential organisms for bioremediation of coal waste.Chlorella sp. merupakan mikroalga bersel satu yang banyak tumbuh di perairan laut. Chlorella sp. dapat tumbuh di perairan yang tercemar berat sehingga berpotensi sebagai bioremediator. Penelitian ini bertujuan untuk menganalisis pengaruh konsentrasi batubara terhadap pertumbuhan Chlorella sp. dan kualitas air pada media kultur Chlorella sp. Metode yang digunakan dalam penelitian ini adalah metode eksperimen skala laboratorium. Rancangan percobaan yang digunakan adalah rancangan acak lengkap dengan 4 perlakuan konsentrasi batubara 0 ppt, 1 ppt, 3 ppt dan 5 ppt. Hasil penelitian menunjukkan bahwa batubara dengan konsentrasi yang berbeda tidak berpengaruh nyata terhadap laju pertumbuhan Chlorella sp (P0,05). Kepadatan antara konsentrasi 0 ppt, 1 ppt, 3 ppt dan 5 ppt tidak terlalu jauh berbeda. Konsentrasi batubara juga tidak berpengaruh nyata terhadap parameter suhu, salinitas dan derajat keasaman (pH) (p0,05). Chlorella sp. dapat tumbuh pada lingkungan yang tercemar oleh batubara, sehingga dapat dipakai sebagai organisme yang berpotensi untuk bioremediasi batubara.

Abstract

Protein is one of the most important components that can support the growth and development of catfish. The price of feed with high protein content which is relatively expensive is a big problem in the catfish farming process. On the one hand, there is shrimp head waste which is a source of protein with a protein content of 42.16% - 49.8% which has not been utilized and is disposed of as waste. Through this research, the shrimp head waste was carried out by an enzyme hydrolysis process to produce shrimp soluble extract (SSE) using a protease enzyme. The SSE that has been produced is then given to catfish aged 14 days to support the addition of protein sources for the growth of catfish. During the 1 month trial, there was a significant difference in results in the treatment catfish with the addition of 2% SSE compared to the control catfish. The addition of SSE gave a very good effect on the weight of catfish which was randomly distributed in a tank containing 50 catfish with an average initial weight of 0.6-0.8 grams. The provision of SSE was carried out simultaneously with the provision of standard fish feed, namely 3 times a day. The increase in catfish weight after being treated was about 2 grams/week. This indicates that SSE can increase the growth of catfish and can be used as an alternative supplement in the future because in addition to reducing the level of pollution due to catfish waste, it can also be a new discovery in the field of fisheries.

Abstract

The purpose of this study was to analyze the socio-economic impact of the community as beneficiaries of Idi fishing port (PPN) and to formulate a strategy to increase people's income. The method used in this research is descriptive method and case study, where descriptive method is used to collect data about the condition and activity of Idi fishing port operation within 5 (five) years, while the case study method is used to know the socio-economic condition of the community as the beneficiary ports, where the data were taken are workers within the port area as well as direct or indirect beneficiaries of port activities with a focal point on fishing communities as the largest workers in the port area. Formulation of income generation strategy using SWOT analysis. The results of the study explain that the condition of the community around the of Idi fishery port is not much different from the condition of other coastal communities where education is not the main priority. In addition, the amount of income in general is still strongly influenced by fish production and ship visits and has not yet met the needs of household fishermen's expenditure. Strategies that can be used to increase people's income is through increased efficiency in the preparation of facilities and infrastructure so that the process of fishing and loading and unloading fish can be faster, saving time and saving cost. Further information on the location of fishing ground and encourage the use of frozen freezer on board is recommended to be done so that the cost of fishing is cheaper and fish prices higher. Tujuan penelitian ini adalah untuk  menganalisis dampak sosial ekonomi masyarakat nelayan sebagai penerima manfaat Pelabuhan Perikanan Nusantara (PPN) Idi serta merumuskan strategi peningkatan pendapatan masyarakat. Metode yang digunakan dalam penelitian adalah metode deskriptif dan studi kasus, dimana metode deskriptif digunakan untuk mengumpulkan data mengenai kondisi dan aktivitas operasional  PPN Idi dalam jangka waktu 5 (lima) tahun. Perumusan strategi peningkatan pendapatan masyarakat menggunakan analisis Internal Strengths dan weaknesses serta lingkungan Eksternal Opportunities dan Threats (SWOT). Hasil penelitian menjelaskan bahwa kondisi masyarakat nelayan disekitar PPN Idi tidak jauh berbeda dengan kondisi masyarakat pesisir lainnya dimana pendidikan bukan prioritas utama. Selain itu jumlah pendapatan secara umum masih sangat dipengaruhi oleh produksi ikan serta kunjungan kapal. Strategi yang bisa digunakan untuk meningkatkan pendapatan masyarakat yaitu melalui peningkatan efisiensi dalam penyiapan sarana serta prasarana sehingga proses nelayan berangkat dan bongkar muat ikan bisa lebih cepat, menghemat waktu dan biaya. Selanjutnya informasi lokasi keberadaan ikan secara berkala serta mendorong penggunaan freezer beku diatas kapal direkomendasikan untuk dilakukan sehingga biaya melaut lebih murah dan harga ikan lebih tinggi.
