Abstract

One of the reptiles whose natural habitat is in the sea and has the ability to migrate very far is the turtle. Threats that endanger the turtle population, both directly and indirectly, come from natural sources and from human activities. The factors that influence turtle nesting ground were predators, sand grain size, substrate humidity, substrate temperature, beach width, coastal vegetation and beach slope. Humans as one of the predators of the availability of turtles in nature by taking turtle eggs. The aim of the study was to determine the nesting habitat characteristics of the Lekang turtle (Lepidochelys Olivaceae) in the coastal area of Gampong Geulumpang, East Sulu, Dewantara District, North Aceh Regency. This research was carried out in November 2021, which took place on the coast of the village of Gelumpang, East Sulu, Dewantara District, North Aceh Regency. In this study, observational data collection and biophysical measurements were set at 3 stations. Station 1 (Dusun Cot U Sibak), station 2 (Dusun Pasie Kuala), and station 3 (Dusun Teupin). The distance between stations in this study was ± 2 km. Data analysis was carried out by weight body and scoring methods. Based on the results of data analysis from three observation stations at turtle nesting locations from several parameters such as beach slope is 4.5-9.3%, beach width is 10.20 -22 meters, the sand temperature is 29-32 0C, humidity is 21-28%, the size of the sand grains is 0.15322-0.31601 mm, while the coastal vegetation is 16.7-49.4%, it is concluded that the three observation stations are in the very suitable category for turtle nesting locations

Abstract

Pupuk organik merupakan bahan organik yang berasal dari tanaman atau hewan yang sudah melalui proses penguraian. Secara fisik pupuk organik dibedakan menjadi dua jenis, yaitu pupuk organik padat dan pupuk organik cair. Urin sapi salah satu pilihan untuk meningkatkan ketersediaan, kecukupan, dan efisiensi serapan hara bagi tanaman yang mengandung mikroorganisme, sehingga dapat mengurangi penggunaan pupuk anorganik (NPK) dan meningkatkan hasil tanaman secara maksimal. Urin sapi merupakan salah satu zat pengatur tumbuh yang dapat digunakan, selain relatif lebih mudah diperoleh juga sederhana penggunaannya. Gampong Keude Blangmee Pulo Klat  merupakan salah satu tempat  yang memiliki lokasi peternakan sapi serta limbah sapi khususnya urine sapi yang belum bisa dimanfaatkan secara maksimal. Berkaitan dengan permasalahan diatas maka tim pelaksana Pengabdian Kepada Masyarakat bertujuaan untuk meningkatkan ketrampilan dan pengetahuan masyarakat  Gampong Keude Blangmee Pulo Klat dalam memanfaatkan urine sapi menjadi POC dengan cara memberi penyuluhan, pelatihan dan pendampingan tentang teknik pembuatan POC urine sapi dan cara aplikasi pada tanaman sayuran. Kegiatan ini dilakukan supaya masyarakat dapat meminimalisir penggunaan pupuk kimia, karena POC urine sapi memberi efek jangka panjang yang baik bagi tanah, yaitu dapat memperbaiki struktur kandungan organik tanah, merangsang pertumbuhan akar tanaman pada benih/bibit serta ramah lingkungan dan memberi keuntungan secara ekonomis. POC urine sapi  yang diaplikasi pada tanaman sayur –sayuran  dengan  dosis 300 ml per liter air pada umur 14 dan 21 hari. Kelebihan dari aplikasi pupuk organik cair adalah dapat menghasilkan sayuran organik yang bebas dari bahan kimia sehingga  tidak menimbulkan pencemaran lingkungan.

Abstract

Usaha budidaya perikanan merupakan sebuah usaha pemeliharaan ikan mulai dari pembenihan, pemeliharaan, pemberian pakan sampai pemasaran ikan. Dalam usaha budidaya ikan tidak terlepas dari pakan ikan, karena pakan merupakan biaya terbesar dalam produksi mencapai 60- 70% dari biaya produksi ikan. Pakan ikan selama ini memiliki kendala salah satunya yaitu harga pakan yang tinggi yang tidak mengimbangi harga jual ikan sehingga pembudidaya merasa kewalahan dalam hal pakan ikan, apalagi pakan dengan protein tinggi sudah pasti harganya jauh lebih mahal dibandingkan dengan pakan dengan protein rendah. Metode pendekatan dalam kegiatan pengabdian ini adalah metode edukatif, partisipatif, dan persuasif. Prosedur kegiatan pengabdian kepada masyarakat ini terdiri atas beberapa tahapan, yakni: (1) Penyuluhan tentang pakan ikan buatan berbahan baku limbah, (2) penyuluhan tentang pengenalan berbagai bahan baku limbah yang berpotensi untuk dijadikan bahan pakan, (3) penyuluhan tentang teknologi pembuatan pakan ikan, (4) pelatihan dalam tahapan pembuatan pakan ikan. Hasil yang dirasakan adalah terjadi perubahan tambahan pengetahuan dan pengalaman serta skil peserta pengabdian tentang pemanfaatan bahan baku limbah untuk pembuatan pakan ikan mandiri.

Abstract

AbstrakPenelitian ini bertujuan untuk mengetahui pengaruh pakan yang ditambahkan tepung hipotalamus sapi terhadap laju pertumbuhan optimal pada benih Ikan Gurami (Oshpronemus gouramy, L). Penelitian ini diharapkan dapat dijadikan solusi untuk optimalisasi pertumbuhan benih Ikan Gurami (Oshpronemus gouramy) dengan menggunakan pakan yang diberi tambahan tepung hipotalamus sapi. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap Non Faktorial dengan 5 perlakuan dan 3 ulangan, yakni perlakuan A (Kontrol), B (Tepung hipotalamus sapi 0,05% /gr pelet), C (Tepung hipotalamus sapi 0,10% / gr pelet), perlakuan D (Tepung hipotalamus sapi 0,15% / gr pelet) dan perlakuan E (Tepung hipotalamus sapi 0,20%/gr pelet). Parameter yang diamati adalah pertumbuhan berat, pertumbuhan panjang, kelangsungan hidup dan kualitas air. Hasil penelitian menunjukkan bahwa penambahan tepung hipotalamus sapi ke dalam pakan pellet berpengaruh nyata terhadap pertumbuhan panjang dan pertumbuhan bobot benih ikan gurami namun tidak berpengaruh nyata terhadap kelangsungan hidup ikan gurami (Oshpronemus gouramy). Pertambahan panjang tertinggi yaitu pada perlakuan C (0,29 cm) pertambahan bobot tertinggi yaitu pada perlakuan C (0,35 gr) dan kelangsungan hidup tertinggi yaitu terdapat pada perlakuan B dan C mencapai 76,66 %. Nilai kisaran kualitas air adalah suhu berkisar antara 24-26 0C, pH 6,6 - 7,1, DO antara 4,6 - 5,2 mg/L dan amonia berkisar antara 0,001- 0,296 mg/L.Kata kunci: ikan gurami; tepung hipotalamus sapi; kelangsungan hidup; laju pertumbuhanAbstractThis study aims to determine the effect of addition the cows hypothalamous flour to comercial feed, in the optimal growth rate in gourami fingerling (Oshpronemus gouramy, L). The benefits of this study are expected to be used as a solution to optimize the growth of gourami fish fingerling (Oshpronemus gouramy, L) by using feed which is supplemented with cow hypothalamic flour. The design used in this study was a Non-Factorial Completely Randomized Design with 5 treatments and 3 replications, namely treatment A (Control), B (Cow hypothalamic flour 0.05% / g pellets), C (Cow hypothalamic flour 0, 10% / g pellets), treatment D (cow hypothalamic flour 0.15% / g pellets) and treatment E (cow hypothalamic flour 0.20% / g pellets). The parameters observed were weight growth, length growth, survival rate and water quality. The results showed that the addition of cows hypothalamus flour into pellet feed significantly affected the long growth and growth of gourami fingerling weight but did not significantly influence the survival of gourami (Oshpronemus gouramy, L). The highest length increase is in treatment C (0.29 cm) the highest weight gain is in treatment C (0.35 gr) and the highest survival is found in treatment B and C reaching 76.66%.

Abstract

Microalgae is one of the natural resources that has the potential to make biodiesel because it contains a fairly high amount of oil. The content of fat (lipid) and fatty acid (fatty acid) in microalgae is a source of energy and is used as raw material for biodiesel. In lipids there are elements of saturated fatty acids that play a role in the process of making biodiesel. The addition of growth nutrients into microalgae culture media is considered the most influential aspect on the quantity of biomass produced by microalgae cultivation. This study aims to determine the effect of chicken manure on the growth rate of Nannochloropsis sp. and to get the best treatment the lipid content of Nannochloropsis sp. of dry weight. The method used in this study was to use a non-factorial Complete RandomIzed Design (RAL) with 3 repeat treatments. The treatments in this study were A: 0 mg/L, B: 250 mg/L, C: 300 mg/L, D: 350 mgL. The results showed that the effect of giving chicken manure with different doses had a very real effect on the density of Nannochloropsis sp, and population peaks. Treatment B with a dose of 250 mg/L of showed the best results with an average density value of 4713 x 104 cells/ml and a population peak of 9415 x 104 cells/ml and the highest lipid levels found in treatment B, which is 12.73.  Water quality during the study was conditioned standard. Temperature 26 - 27 oC, pH 7.1 - 7.7, DO 5.2 - 6.3 and salinity 31 - 34 ppt. Based on the results of the study found that lipid results are high, so it is possible to try biodiesel testing.Keywords: Biodesel; Biomass; Lipid; Microalgae; Nannochloropsis  sp
