Abstract

Penelitian ini bertujuan untuk mengetahui pertumbuhan dan tingkat kelulushidupan serta perbedaan rasio konversi pakan ikan nila yang diberikan pakan rucahan ikan red devil dengan persentase berbeda. Penelitian dilaksanakan pada kurun waktu 56 hari, menggunakan tiga perlakuan yakni A (kontrol) pemberian pakan 100% pelet, perlakuan B pemberian pakan rucah ikan red devil 100%, dan perlakuan C pemberian pakan pelet 50% + rucahan ikan 50%. Padat tebar ikan dalam penelitian ini adalah 20 ekor/50 liter air dengan ukuran ikan 4-6 cm yang diperoleh dari petani pendederan di daerah Bangli. Parameter yang diamati dalam penelitian ini adalah pengukuran panjang ikan, laju pertmbuhan spesifik, kelulushidupan, rasio konversi pakan dan kualitas air. Hasil dari penelitian yang telah dilaksanakan menunjukkan bahwa perlakuan C memberi hasil yang tertinggi dan berbeda nyata secara stastistik (P<0.05) pada pertumbuhan panjang mutlak dan kelangsungan hidup ikan. Hasil pengukuran parameter kualitas air selama penelitian menunjukkan suhu berkisar 23.80-24.18oC, nilai pH rata-rata 7.03 dan DO pada kisaran 5.82-6.13 mg/L. Nilai kualitas air ini masih berada dalam rentang optimum untuk pemeliharaan ikan nila. Kata Kunci: Ikan Nila; Ikan red devil; Laju Pertumbuhan

Abstract

Abstract This study was conducted in Pandan Beach, Pandan District, Central Tapanuli, North Sumatra which aims to know the supporting factors of coastal tourism feasibility from the limiting factors of tourism conformity index value and to know the tourism conformity index (IKW). This research was conducted for 1 Month, namely in early March to early April 2021. The method used in this study is descriptive quantitative method. Determination of the location of research based on the representation of the area is located with the consideration that in the area is often carried out tourist activities such as point 1 waterspot activities, point 2 is swimming activity and point 3 ship activity that carries passengers around the island. parameters measured in the Index of Tourism Conformity Category Of Beach Tourism namely depth, tipe beach, beach width, water base material, beach slope, current speed, brightness, closure of coastal land, hazardous biota, and availability of fresh water. Based on the observation of the potential of Pandan Beach is the white sand, the waves are not too besar. The results showed the value of tourist conformity index of the three stations, namely at station 1 has a value of 2,695, while at stations II and III has the same value of 2,795. It shows that pandanus beach falls into the category of very appropriate (SI) with a conformity index value of >2.5. Hal showed that Pandan Beach Tapanuli Central North Sumatra has a very good potential to be a location for recreational beach tourism activities. Keywords: Potential; Tourism Conformity Index; Pandan Beach.

Abstract

Identification is necessary to identify the identity of an organism. Fish can be identified morphologically, namely by recognizing physical characteristics and looking for differences in the fish. This research was carried out for 3 months, from sampling, laboratory activities, and data analysis, starting from January 2021 to March 2021. Sampling was taken universally, samples were obtained from fishermen in the coastal waters of South Bali who caught eels. Laboratory activities are carried out at Fisheries Laboratory, Udayana University. This study used a descriptive analysis method. The sampling technique used in this study was probability sampling with simple random sampling. The stages carried out in this study were divided into two stages, including (1) sampling and (2) identification of morphological characters. The eel samples were obtained based on morphological identification of physical observation, eels are known to have a mottled pattern with slightly rounded oval tails and long fins. The morphometric measurements also obtained the results of the pre-dorsal length (PDL) ratio of 27.98%, the head length (HL) ratio of 14.14%, the ano-dorsal length (AD) ratio of 18.79%, and the ratio of pre-anal length (PAL) of 46.54%. The morphologically and morphometrically identified eel samples were identified as Anguilla marmorata.
