Judul: Waste from Pot Fishery Operation and its Management Strategies in Indramayu District
Abstrak: Sampah operasional adalah sampah yang dihasilkan dari kegiatan di kapal saat trip penangkapan ikan, meliputi alat tangkap dan sampah perbekalan. Sampah dari alat tangkap ini dapat menghasilkan Ghost gear. Ghost gear adalah alat tangkap yang hilang, dibuang, dan ditinggalkan di perairan dan masih mempunyai kemampuan menangkap ikan. Pada Desa Karangsong, Kecamatan Indramayu, sering terjadi kasus jaring aktif menyeret tali bubu dan menyebabkan hilangnya 100-200 bubu. Tujuan penelitian ini adalah mengestimasi ghost gear, identifikasi faktor penyebabnya, merumuskan penanggulangannya, dan mengestimasi limbah dari aktivitas penangkapan bubu. Penelitian ini dilakukan di PPI Karangsong dengan metode survei. Analisis yang digunakan adalah analisis statistik dan deskriptif. Hasil penelitian menunjukkan bahwa estimasi ghost gear bubu adalah 28.178 unit/tahun. Faktor hilangnya bubu tertinggi adalah konflik dengan nelayan lain. Sementara faktor tertinggi bubu dibuang dan ditinggalkan adalah bubu rusak. Rumusan penanggulangan ghost gear di kecamatan Indramayu adalah pendataan lewat asosiasi nelayan lokal serta dialog dengan nelayan jaring aktif. Estimasi limbah yang dihasilkan nelayan bubu Kecamatan Indramayu adalah sekitar 4.961,93 Kg/tahun., Operational waste is generated from fisheries activity, including fisherman's supplies and fishing gear waste. Fishing gear waste can produce Ghost gear. Ghost gear is fishing gear that is lost, discarded, or abandoned in the waters and still can catch fish. In Karangsong Village, Indramayu District, there are frequent cases of active nets dragging trap ropes and causing the loss of 100-200 pots. This research aims to estimate ghost gear, identify the causal factors, formulate mitigation efforts, and assess waste from trap fishing activities. This research was conducted at PPI Karangsong using a survey method. The analysis used is statistical and descriptive. The research results show that the estimated ghost gear trap was 28,178 units/year. The highest factor in fish trap loss was conflict with other fishermen. Meanwhile, the highest factor for traps being discarded and abandoned is damaged traps. The recommended ghost gear mitigation is data accumulation through local fishermen's associations and dialogue with active net fishermen. The estimated waste produced by trap fishermen in Indramayu District was around 4,961.93 kg/year.

Judul: Estimating Ghost Gear in Gillnet Fisheries and Coping Strategies at the Cilacap Fishing Port, Central Java
Abstrak: Ghost gear merupakan alat tangkap yang hilang, ditinggalkan, atau dibuang di lingkungan laut dan dapat menjerat ikan meski tidak dioperasikan. Penyumbang utama ghost gear adalah jaring insang dan sebanyak 44% jaring insang dioperasikan di Pelabuhan Perikanan Samudera (PPS) Cilacap sehingga potensi ghost gear di PPS Cilacap cukup tinggi. Penelitian ini bertujuan untuk mengestimasi jumlah ghost gear, mengetahui faktor penyebab terjadinya ghost gear, serta merekomendasikan upaya penanggulangan ghost gear pada perikanan jaring insang di PPS Cilacap. Penelitian dilakukan menggunakan metode survei, pengambilan data dengan teknik wawancara dan pengamatan langsung pada kapal berukuran <5 GT. Analisis yang digunakan adalah analisis statistik dan deskriptif. Hasil penelitian menunjukkan 94% nelayan jaring insang di PPS Cilacap pernah mengalami ghost gear. Diestimasikan jumlah ghost gear yang terjadi dalam satu tahun terakhir adalah 1.626 pieces dengan total kerugian mencapai Rp310.972.500,00. Faktor penyebab ghost gear dikategorikan menjadi aspek alam, sosial, dan teknis. Upaya penanggulangan yang dapat dilakukan adalah sosialisasi terkait ghost gear, standarisasi gear marking, mewajibkan nelayan melapor, penyediaan fasilitas penampungan sampah alat tangkap dan pemberian insentif, serta penggunaan teknologi modern. kata kunci: alat tangkap, ghost gear, jaring insang, sampah laut, Ghost gear refers to fishing gear lost, abandoned, or discarded in the marine environment, which can still entangle fish even when not used. Gillnets are the primary contributor to ghost gear, with up to 44% of gillnets operated at the Cilacap fishing port (PPS). Consequently, the potential for ghost gear at PPS Cilacap is relatively high. This study aims to estimate the amount of ghost gear, identify the factors causing it, and recommend countermeasures for gillnet fisheries at PPS Cilacap. The research was conducted by survey methods, collecting data through interviews and direct observations on boats under 5GT. Both statistical and descriptive analyses were used. Results indicated that 94% of gillnet fishermen had encountered ghost gear. An estimated 1,626 pieces of ghost gear were lost in the past year, amounting to a total loss of Rp310,972,500. Factors contributing to ghost gear include natural, social, and technical aspects. Suggested countermeasures involve raising awareness about ghost gear, standardizing gear marking, mandating reporting by fishermen, providing disposal facilities and incentives, and implementing modern technology.

Judul: Gambaran Leukosit Domba Ekor Tipis yang Diinfeksi Haemonchus contortus.
Abstrak: The aim of this study was to investigate the effect of Haemonchus contortus infection to white blood cell profile of Javanese thin tail sheep. Twenty males Javanese thin tailed sheep were divided into five groups, namely infected group of 500 L3, 1000 L3, 2000 L3, 4000 L3 and uninfective group as control. The blood and fecal samples were collected from rectum before and three weeks after infection. The blood samples were collected using venoject® from Jugular vein. The fecal samples were collected directly from rectum. The blood samples were examined to determine total of white blood cell (leukocytes) and white blood cell differential, whereas fecal samples to determine egg per gram. The result showed that Haemonchus contortus infections cause an increased total of leukocyte but were not significantly different among of level infection doses (P>0.05). Number of eosinophils were significantly different among uninfected group (P<0.05), but were not significantly different in number of lymphocyte, monocyte, and neutrophil (P>0.05). There where positively correlated significantly between the amount of egg per gram (EPG) and profile of eosinophil (P<0.05), however were negatively correlated significantly between the amount of egg per gram (EPG) and neutrophil’s profile (P<0.05). There where no correlation significantly between the amount of egg per gram (EPG) and profile of white blood cell, lymphocyte, and monocyte (P>0.05).
