Mangrove forest is one of the important ecosystems in Karimunjawa, Indonesia. It provides a variety of services both ecologically and economically. However, over-exploited activity, such as timber theft, can be threatening the sustainability of mangrove forest in Karimunjawa now and in the future. Thus, the improved management for mangrove forest is necessary to ensure its sustainability, and it is depending on how people value the conservation from economic and environment consideration. This study examines the factors influencing on the willingness to pay (WTP) of respondents for mangrove restoration in Karimunjawa. A total of 502 respondents were interviewed using census method. The method employed is Contingent Valuation Method (CVM)Single Bounded. In CVM, the logit model was defined based on dichotomous choice method to estimate the willingness-to-pay (WTP) randomly with three different starting bid value. Findings showed that local awareness of the importance of the values given by mangroves was popularized among local communities. The findings also indicated that respondents who are higher education and have more income were more likely to pay for the mangrove restoration.

Kualitas hasil perikanan dipengaruhi oleh kondisi tempat pemasaran ikan di pelabuhan perikanan. Penunjang utama keberhasilan peningkatan mutu di Pelabuhan Perikanan Samudra (PPS) yaitu dengan membuat konsep pemasaran ikan higienis, salah satunya di PPS Cilacap. Pembangunan tempat pemasaran ikan (TPI) higienis PPS Cilacap ini dilandasi oleh Keputusan Direktorat Jendral Perikanan Tangkap (DJPT) no 7 tahun 2017 tentang petunjuk teknis TPI higienis di pelabuhan perikanan. Tujuan penelitian adalah mengkaji dan mendeskripsikan persepsi penguna jasa terhadap penerapan tempat pemasaran ikan higienis dengan metode analisis bersifat deskriptif. Hasil penelitian ini menunjukan bahwa persepsi pengguna jasa terhadap tempat pemasaran ikan higienis di PPS Cilacap dari aspek fasilitas mayoritas penerapan tinggi yaitu nilainya di atas 146,67, akan tetapi kondisi (lantai, ventilasi, fasilitas/peralatan penunjang pemasaran higienis) beberapa dinilai rendah yaitu kurang dari 93,33 dan fasilitas seperti roller conveyor, cool box, mesin penghancur es (ice crusher) tidak terdapat di PPS Cilacap. Aktivitas bongkar dan pengangkutan juga memiliki rata-rata persepsi dalam penerapan tinggi yaitu nilainya diatas 146,67. Penanganan ikan di TPI higienis PPS Cilacap tidak dilakukan pelelangan, tidak dilakukan pensotiran di meja sortir dan pelabelan. Partisipasi nelayan dalam pemasaran menjadi berkurang akibat tidak diadakannya pelelangan. Oleh karena itu perlu dilakukan perbaikan penerapan, baik fasilitas yang sudah mulai mengalami kerusakan, serta perlunya penambahan fasilitas untuk memperlancar aktivitas.Title: Fishers Perception on Hygienic Fish Market at Cilacap fishing portThe quality of fisheries products subject to condition of the fish market. The key concept of fish quality at Cilacap was fishing port due to the existence of hygienic fish market. Decision Letter of the Director General of Capture Fisheries No.7/2017 regarding the technical guidelines for hygienic fish market at the fishing port has been the basis of the development of hygienic fishing port in Cilacap. This study aimed to asses and describe public perception on the hygienic fish market using a descriptive method. The study showed that public perception on hygienic fish market at Cilacap fishing port was above 146.67 in terms of its facilities. The condition of some facilities (flooring, ventilation, facilities or other equipment that support hygienic marketing) were classified under 93.33, while some equipment such as roller conveyor, cool box, ice crusher were not available at Cilacap fishing port. Unloading and transportation presented a high average perception in the application above 146.67. There are no auction, sorting on the sorting table, and labelling in the fish handling at hygienic fishing port since there is no auction Cilacap. There was a decreased participation of fishers in fish marketing. Therefore, it is necessary to improve application of hygienic fish handling by repairing the damaged facilities and establishing more additional equipment.

Kualitas air merupakan salah satu faktor penting dalam budidaya, walaupun ikan lele mampu bertahan hidup dalam kondisi kualitas air yang buruk namun keadaan itu akan berpengaruh pada pertumbuhannya. Pada penelitian ini bertujuan untuk mengetahui pengaruh ekoenzim terhadap kualitas air pada pembesaran ikan lele. Penelitian dilakukan pada bulan April - Mei 2018 di Laboratorium Pengelolaan Sumberdaya Ikan dan Lingkungan, Fakultas Perikanan dan Ilmu Kelautan, Universitas Diponegoro,Semarang. Metode yang digunakan pada penelitian ini adalah metode eksperimen di laboratorium dengan menggunakan desain penelitian yaitu rancangan acak lengkap (RAL). Penelitian ini dilakukan dengan menggunakan 4 perlakuan yaitu kontrol, 0,1 ml/L, 0,5 ml/L, dan 1 ml/L dengan 3 pengulangan. Pada penelitian ini menggunakan analisis data one way Anova dengan menggunakan data konsentrasi amoniak dan nitrit sedangkan konsentrasi DO, pH, temperature , dan Pertubuhan menggunakan analisis deskriptif. Hasil analisis data yang telah dilakukan menunjukan bahwa tidak ada perbedaan rata-rata hasil konsentrasi amoniak dan nitrit dengan konsentrasi ekoenzim yang berbeda. Jadi pemberian ekoenzim di media pemeliharaan ikan lele menunjukan hasil yang baik untuk proses budidaya namun masih kurang baik untuk pertumbuhan ikan lele tersebut, karena didapatkan hasil pertumbuhan ikan lele cenderung lambat. Water quality is an important factor in cultivation, although catfish are able to survive under poor water quality conditions but the situation will affect its growth. In this study aims to determine the effect of eczymes on water quality in the enlargement of catfish. The study was conducted in April - May 2018 at the Fish and Environmental Resource Management Laboratory, Faculty of Fisheries and Marine Sciences, Diponegoro University, Semarang. The method used in this study is an experimental method in the laboratory using a research design that is a completely randomized design (CRD). This research was conducted by using 4 treatments, namely control, 0.1 ml / L, 0.5 ml / L, and 1 ml / L with 3 repetitions. In this study used one way Anova data analysis using ammonia concentration data and nitrite concentration while DO, pH, temperature, and Growth using descriptive analysis. The results of the data analysis that has been carried out show that there is no difference in the average yield of the concentration of ammonia and nitrite with different eczene concentrations. So ekoenzim peberian in catfish breeding media showed good results for the cultivation process but still not good for the growth of catfish, because the results obtained growth of catfish tend not slow.
