Abstract

Ikan toman sebagai salah satu ikan lokal bernilai ekonomis tinggi kini telah beradaptasi dengan pakan buatan. Guna meningkatkan laju pertumbuhan ikan toman diperlukan suplemen atau probiotik. Spesies bakteri probiotik lactobacillus sp didapatkan dari lauratan probiotik dari berbagai merek dagang di pasaran. Rancangan penelitian menggunakan metode RAL, dengan 3 perlakuan 3 ulangan dan satu perlakuan kontrol. Tiap perlakuan menggunakan pakan buatan dengan dosis 10 ml/kg pakan dengan spesies bakteri lactobacillus sp pada Perlakuan A yaitu Lactobacillus acidophilus, perlakuan B yaitu Lactobacillus casei , perlakuan C yaitu Lactobacillus acetobacer, dan Kontrol tanpa pemberian probiotik. Pemberian pakan dilakukan 3 kali sehari, pagi, siang dan sore hari dengan lama pengamatan dilakukan selama 60 hari. Sampling pertumbuhan dilakukan setiap 15 hari sedangkan pengamtan kelangsungan hidup dilakukan tiap hari. Data yang diambil dan dianalisis meliputi laju pertumbuhan mencakup mutlak dan relatif, tingkat kelangsungan hidup, dan FCR. Analisis data dilakukan menggunakan analisis sidik ragam Anova. Hasil yang diperoleh menunjukan laju pertumbuhan dan nilai FCR yang terbaik terdapat pada Perlakuan A dengan laju pertumbuhan berat mutlak 19,88 gram dan laju pertumbuhan berat relatif 29,53% serta nilai FCR 3,71, selanjutnya diikuti oleh perlakuan B dengan laju pertumbuhan berat mutlak 19,56 dan relatif 29,05% serta nilai FCR 3,81. Urutan berikutnya perlakuan C dengan laju pertumbuhan berat mutlak 19,24 gram dan relative 28,54% serta nilai FCR 3,89. Kontrol memberikan laju pertumbuhan yang terendah dibandingkan dengan 3 perlakuan lainnya dengan laju pertumbuhan berat mutlak 19,22 gram dan relatif 28,51% serta nilai FCR 3.96. Perlakuan pemberian ragam spesies bakteri probiotik tidak berpengaruh signifikan terhadap tingkat kelangsungan hidup ikan toman, dimana nilai prosentase kelangsungan hidup selama pemeliharaan berkisar antara 83-86%.

Abstract

The sustainability of vannamei shrimp (L. vannamei) aquaculture activities is very dependent on the health of the vannamei shrimp being reared, the health of the vannamei shrimp is greatly influenced by biotic (pathogenic bacteria) and abiotic (environmental stress) factors which together affect their survival. This study aims to analyze the relationship and distribution of salinity, dissolved oxygen, and pH variables for the distribution of Vibrio sp. The results show that the salinity has a strong effect on the presence of Vibrio sp. in the shrimp pond area with a value of 0.008495, while pH and dissolved oxygen did not have a strong influence on the presence of Vibrio sp. bacteria with values ​​​​of 0.470479 and 0.663797 respectively. Therefore, it was concluded that it is important to control the salinity value so that it is not too high or too low with a value in the range of 18 – 20 ppt. Then even though pH and dissolved oxygen do not affect the presence of bacteria, these two parameters greatly affect the vannamei shrimp immune system which can make it easier for Vibrio sp. bacteria to develop and infect.

Abstract

Ulva lactuca contains various bioactive compounds, and has been developed by many recent researchers into cosmetic products, especially for skin. In addition, other types of plants that can be used for cosmetics, namely Aloe vera which has lots of nutrients and vitamins for the skin. This study aims to obtain the best body lotion formulation from U. lactuca and A. vera based on thwphysical evaluation. The process of making body lotion consists of two stages, namely the oil phase and the water phase, then homogenized at 70-75°C. The formulation in the study varied with the addition of U. lactuca and A. vera with a ratio of 1:2 (F1), 1:1 (F2), 2:1 (F3) and F0 as a control treatment. The body lotion formulation with a ratio of 1:2 (F2) has a good moisture level for the skin and a pH value that is suitable for the skin, and all treatments have spreadability that meets the standards. All treatments have an oil-in-water emulsion type. In centrifugal testing no phase is formed. The organoleptic test results for all products ranged from moderate to like. The results of this study indicate that the F1 formulation is the best formulation of all treatments because it has a good pH and moisture value for the skin.

Abstract

Birgus latro L. adalah kepiting pertapa darat terbesar di dunia. Spesies ini tersebar luas di pulau-pulau terpencil Indo-Pasifik di daerah tropis, tetapi populasinya menurun drastis. Tujuan penelitian ini mengidentifikasi ekologi dan kelimpahan relatif dari keberadaan Birgus latro L. di Pulau Kadatua, Kabupaten Buton, Sulawesi Tenggara. Metode penelitian yang dilakukan dengan pendekatan kuantitatif dan observasi lapangan. Pengumpulan data dilakukan melalui survei visual, uji parameter lingkungan, dan morfometrik kepiting kelapa. Berdasarkan hasil penelitian memperlihatkan bahwa kepiting kelapa hadir dalam kondisi tertentu dan dipengaruhi oleh kondisi lingkungannya. Habitat kepiting kelapa ini lebih menyukai tekstur tanah berpasir-lempung dengan suhu tanah antara 28-30°C dan kelembaban antara 70-90%. Curah hujan, pH tanah, dan vegetasi sekitar habitat Birgus latro L. mempengaruhi kehidupannya seperti ketersediaan sumber makanan dan tempat berlindung dari ancaman predator. Analisis morfometrik dan kelimpahan kepiting kelapa berdasarkan 4 stasiun pengamatan memperlihatkan bahwa rata-rata ukuran dan berat kepiting kelapa bervariasi yang dipengaruhi oleh lokasi habitatnya. Semakin dekat dari pemukiman masyarakat ukuran kelas panjang karapas kepiting kelapa semakin kecil, sebaliknya apabila kehidupan kepiting kelapa berada jauh dari pemukiman dan aktivitas manusia maka ukuran kelas panjang karapas kepiting kelapa akan semakin besar dan jumlah populasinya semakin banyak. Kelimpahan relatif memperlihatkan bahwa kepiting kelapa hampir tidak ditemukan pada malam hari tanpa umpan. Penelitian ini memiliki implikasi penting dalam pengelolaan ekosistem pesisir, khususnya dalam upaya konservasi kepiting kelapa dan habitat-habitatnya. Selain itu, penelitian ini juga dapat menjadi sumbangan pengetahuan dalam konteks ekologi kepiting kelapa secara lebih luas di wilayah Sulawesi Tenggara.

Abstract

Milkfish satay is one of the signature dishes from the Banten Province that tends to experience a rapid decline in quality. Milkfish satay can only stay fresh for approximately 2 days at room temperature and 6 days when stored in cold conditions. This limited shelf life is due to its high nutritional content and various environmental factors. Therefore, a preservative such as carboxymethyl chitosan (CMC) is needed to extend the shelf life of milkfish satay. The objective of this research is to determine the optimal concentration of CMC that is effective as an antibacterial agent for milkfish satay against Staphylococcus aureus bacteria during cold storage. This study employs an experimental method with a Completely Randomized Factorial Design (CRFD) involving two factors and conducted with two replications. The first factor involves four levels of CMC concentration, namely 0%, 3%, 4%, and 5%. Meanwhile, the second factor encompasses six different storage periods, namely day 0, 3, 6, 9, 12, and 15. The parameters tested include antibacterial activity against Staphylococcus aureus, Total Plate Count (TPC), and proximate analysis of the best treatment. It is important to note that the milkfish satay samples used in this research do not represent all milkfish satay from the Banten Province. The samples were obtained from one of the Micro, Small, and Medium Enterprises (MSMEs) with sanitation compliance not meeting the Standard Operating Procedures (SOP). The research results are presented in tabular form and described descriptively. The findings of the study indicate that the addition of carboxymethyl chitosan (CMC) has an impact on the antibacterial activity of milkfish satay, with the optimal CMC concentration being at 5%.

Abstract

Turtles are reptiles whose lives are almost entirely in the sea. They are able to migrate long distances for several purposes, one of which is laying eggs. One of the places turtles like to lay their eggs is Batu Hiu Beach. At Batu Hiu Beach there is also a turtle hatchery called the Raksa Bintana Foundation. Turtles themselves have been included in the red list on the IUCN and Appendix I CITES due to natural and human threats. The purpose of this research is to find out procedures for evacuating, protecting and caring for turtles at the Raksa Bintana Turtle Conservation Foundation, Batu Hiu Beach, Pangandaran. The method used is a qualitative descriptive method. This foundation carries out turtle conservation starting from the discovery of eggs until the turtles can be released back into the sea. Efforts to transfer (evacuate) the eggs are carried out in less than 12 hours and are incubated in semi-natural hatching nests for 40-60 days. Based on research by the Raksa Bintana Foundation, carrying out the transfer, incubation and maintenance processes was appropriate, resulting in 85% hatching success.
