Abstract

Pari kekeh (Rhynchobatus sp.) adalah organisme laut yang tergolong dalam Subkelas Elasmobranchii dan dikelompokkan ke dalam Kelas Chondrichthyes. Pari kekeh sering ditangkap dikarenakan dagingnya memiliki rasa yang enak, Selain itu, sirip Pari kekeh memiliki harga yang mahal  di China dan Global. Pari kekeh telah masuk kedalam daftar IUCN red list kategori critically endangered akibat eksploitasi berlebihan. Hal ini apabila terus terjadi maka ketersedian sumber daya Pari kekeh di habitatnya terancam punah. Oleh karena itu, perlu adanya pengaturan agar tidak terjadi eksploitasi berlebihan yang berdampak pada populasi pari kekeh, salah satunya dengan melakukan analisis aspek biologi. Tujuan dari penelitian ini untuk mengetahui hubungan panjang berat, nisbah kelamin, tingkat kematangan gonad, ukuran pertama kali matang gonad dan fekunditas Pari kekeh yang didaratkan di PPN Brondong. Sampel yang digunakan yaitu pari kekeh sebanyak 160 ekor. Penelitian ini menggunakan metode deskriptif dengan mengukur data panjang total dan standar, bobot, pengamatan gonad. Pola pertumbuhan Pari kekeh yaitu allometrik negatif (b = 2,52). Nisbah kelamin = 0,625 (Chi Square) dengan X tabel = 3,975, maka jumlah Pari jantan dan betina seimbang. Kematangan gonad Pari Rhynchobatus sp. sebesar 53%. Ukuran pertama kali matang gonad Pari kekeh jantan memiliki panjang total 48,97-49,16 cm dan Pari kekeh betina memiliki panjang total 95,29-98,60 cm. Nilai fekunditas Pari kekeh berkisar antara 5-16 butir pada kisaran panjang total tubuh 86-114 cm.  Kekeh Stingrays (Rhynchobatus sp.) are marine organisms that classified to the Elasmobranchii subclass and grouped into the Chondrichthyes Class.

Abstract

Rajungan (Portunus pelagicus) adalah hewan bercangkang keras seperti kepiting yang memiliki habitat alami hidup di laut dan biasa disebut sebagai Blue Swimming Crab. Rajungan menjadi salah satu komoditas perikanan yang memiliki nilai ekonomis yang tinggi di Indonesia. Tujuan dilakukannya penelitian ini untuk mengkaji tingkat kerentanan Rajungan (Portunus pelagicus) akibat adanya kegiatan penangkapan di Desa Paciran Kecamatan Paciran Kabupaten Lamongan, Jawa Timur. Metode yang digunakan dalam penelitian ini adalah metode Analisis PSA (Productivity and Susceptibility Analysis). Hasil analisa parameter produktivitas didapatkan dari literatur, sedangkan parameter kerentanan didapatkan dari hasil wawancara dengan nelayan setempat. Nilai PSA yang didapatkan sebesar 2,01 yang menunjukkan bahwa tingkat kerentanan masih tergolong rendah, sehingga tekanan aktivitas penangkapan belum berdampak serius terhadap potensi keberlanjutan Rajungan (Portunus pelagicus) sementara hasil pola pertumbuhan menunjukkan pola pertumbuhan allometrik negatif baik jantan dan betina. Hubungan lebar karapas dengan berat rajungan menghasilkan nilai b sebesar 2,37 untuk rajungan jantan dan 2,33 untuk rajungan betina. Sifat pertumbuhan ini menunjukkan bahwa pertumbuhan lebar karapas lebih cepat dibandingkan pertumbuhan berat rajungan. Rata rata lebar karapas yang ditemukan dilokasi penelitian 128 mm pada Rajungan jantan dan 111 mm pada Rajungan betina serta memiliki rata rata ukuran berat 115 gr baik pada Rajungan jantan dan betina.  Blue Swimming Crab (Portunus pelagicus) is a hard-shelled animal like a crab that naturally lives in the sea and is commonly referred to as the Blue Swimming Crab.

Abstract

Epibion merupakan organisme yang hidup melekat pada berbagai jenis substrat alamiah di dasar perairan dan berperan penting sebagai pemakan sisa. Bandengan dan Pulau Panjang adalah dua lokasi pantai berpasir yang terletak berdekatan di Kabupaten Jepara Jawa Tengah. Studi ini menginvestigasi epibion pada makrofit, yaitu makroalgae dan lamun di kedua lokasi, dengan metode survei. Epibion utama kedua jenis makrofit tersebut adalah mikroalgae dan mikrozoobentos, dengan jumlah dan keanekaragaman yang relatif tidak berbeda. Secara lebih detil, epibion utama makroalgae umumnya adalah mikroalgae planktonik dan mikrozoobentos, sedangkan epibion utama lamun adalah mikroalgae planktonik yang bersifat epifit. Struktur komunitas bentik yang mengandung Polychaeta dalam jumlah jenis dan jumlah individu terbanyak dibandingkan Crustacea dan Mollusca, dan tidak dijumpainya genera lamun pionir Halophila dan Halodule di kedua lokasi, mengindikasikan masih cukup baiknya kualitas hayati kedua pantai wisata tersebut. Kata kunci: epibion, lamun, makroalga,  pantai berpasir, Jepara Epibiont ​​is known as living organisms attached to various natural benthic substrates and plays an important role as scavenger. Bandengan and Pulau Panjang are two sandy beaches close to each other located at Jepara, Central Java. This study investigates epibionts on macrophytes, which are macroalgae and seagrasses in both locations, by means of survey method. In general, major constituent of epibionts in those two macrophytes are microalgae and microzoobenthos, with relatively similar individual number and diversity. In more details, epibionts in macroalgae is planktonic microalgae and microzoobenthos, whereas, for seagrass it is of epiphytic microalgae. Benthic community structure which have more abundant and more diverse Polychaeta compared to that of Crustacea and Mollusca, combined with no existence of pioneer seagrass, i.e., Halophila and Halodule indicating that both beaches have still retained relatively good quality ecosystem for tourism.

Abstract

The city of Palangka Raya has 3 faces, namely the city face, the village face and the forest face. The rapid development of the Palangka Raya City area will certainly change every face. The basic idea of this study stems from anxiety in observing the existence of local wisdom which is starting to be eroded by developments over time. Sometimes local wisdom is considered old-fashioned and uninteresting, but this is different from the Dayak tribe, which still has a strong culture. So the urgency of this research problem is to examine the complexity of the development of urban areas which will certainly sacrifice many aspects of forests to become urban areas. Seeing that this problem is multi-faceted, researchers dissect it from the perspective of policy, planning and consistency of sustainable development based on local wisdom. This research aims to investigate the existence of local Dayak wisdom in urban policy and planning in Palangka Raya City. As well as analyzing the consistency of government responsibility for the development of Palangka Raya City. This research uses a design that adopts qualitative research methods. The research approach does not focus on government governance and its implementation, but attempts to find answers to the study through the theory used as an analytical tool, namely CIPP model policy evaluation. The research results show that the existence of local wisdom of the Dayak Tribe in urban area policy in Palangka Raya is quite significant, however, consistency in urban planning based on local wisdom of the Dayak Tribe in Palangka Raya is still going through various dynamics and maintaining it is a challenge
