Abstract

Shrimp Waste Hydrolyzate (SWH) /Shrimp Soluble Extract (SSE) is a product produced from the enzymatic process of shrimp waste. SWH contains essential and non-essential amino acids which useful for fish. This study aimed to determine effect of SWH on the growth and total production of catfish. The parameters observed were average growth rate, specific growth rate (SGR), food conversion ratio (FCR), protein efficiency ratio (PER), total production and length weight relationship from beginning until the end of rearing period. Growth performance was observed by calculating average growth rate and SGR of catfish. The results of this study showed that oral administration of SWH significantly increased SGR of catfish length at 4th sampling period with value 1.54% body length/day. Administration of SWH did not affect on the AGR, FCR, PER and total production. The growth pattern of catfish is negative allometric.

Abstract

Sea grapes have high economic potential. The development of sea grape cultivation is inseparable from its cultivation techniques. The research objective was to determine the daily growth rate and chlorophyll content of sea grapes in different cultivation techniques. The research was conducted from September to November 2020 at the Polytechnic of Marine and Fisheries, Kupang, East Nusa Tenggara. The treatment in this study was a different cultivation technique with 3 treatments, namely by spreading it (scattering technique), using the substrate (substrate technique), and combining the spread and substrate (combined technique). The results showed no difference in daily growth rate and chlorophyll content even though using different cultivation techniques. The intensity of sunlight more influences the daily growth rate and chlorophyll content. Water quality parameters during the study supported the daily growth rate.

Abstract

ABSTRAK Anggur laut (Caulerpa sp.) merupakan salah satu jenis rumput laut yang memiliki nilai ekonomis tinggi yaitu dapat dimanfaatkan sebagai bahan makanan, pangan fungsional, dan obat.Sebagian kecil masyarakat wilayah Nusa Tenggara Timur telah mengenal anggur laut, namun pemanfaatannya masih sangat terbatas sebagai bahan makanan segar saja atau disebut dengan lawar. Anggur laut tersebut diperoleh dari alam sehingga ketersediaannya sangat tergantung dari alam dan kondisi musim. Budidaya merupakan cara yang dapat dilakukan untuk memastikan ketersediaan dan jumlah anggur laut sehingga dapat dimanfaatkan oleh masyarakat secara berkelanjutan. Tujuan kegiatan ini adalah memberikan sosialisasi tentang budidaya serta potensi anggur laut, dan memberikan pelatihan tentang budidaya anggur laut bagi masyarakat Desa Bolok.Kegiatan pengabdian kepada masyarakat ini bermitra dengan Kelompok Tani Rumput Laut “UT LATU” yang beralamat di Dusun III, Desa Bolok, Kupang Barat, NTT.Metode pelaksanaan kegiatan dilakukan dua tahap. Tahap pertama adalah sosialisasi tentang budidaya anggur laut, manfaat anggur laut, produk olahan anggur laut dan tahap kedua adalah pelatihandengan tahapan persiapan alat dan bahan, penimbangan bibit anggur laut, penanaman dalam media tanam berupa PE, penambahan pupuk Guano, pemasukan media tanam ke dalam kontainer box, monitoring pertumbuhan, panen, dan pengawetan sederhana anggur laut.Pada saat panen diperoleh bobot anggur laut berkisar antara 680 – 1210 g dari bobot awal 400 g selama pemeliharaan 30 hari, pertumbuhan relatif diperoleh nilai 70 – 203%. Setelah kegiatan ini dilaksanakan, masyarakat mulai menyadari akanmanfaat anggur laut, dan dapat ditumbuhkan pada kontainer box yang diletakkan di pekarangan rumah sehingga dapat menjadi alternatif kegiatan budidaya oleh masyarakat.

Abstract

Seagrapes (Caulerpa sp.) is one of the aquatic plants which tends to grow slowly according to the environmental conditions where sea grapes live. This study aims to determine the growth performance of sea grapes given different shelters. The method used in this study was three treatments, each treatment was repeated three times, with differences in the shade (P1 = paranet), (P2 = without roof), and (P3 = coconut leaves). Data analysis used a non-factorial completely randomized design (CRD). The results of this study are at absolute weights (P1 =1163.3 ± 260a g), (P2 = 210 ± 79.3b g), (P3 = 922 ± 199.5a g), absolute length (P1 = 5.75 ± 1.74a cm), (P2 = 0.59 ± 0 , 07b cm), (P3 = 4.82 ± 0.22a cm), daily growth rate (4.40 ± 0.1a %), (3.76 ± 0.09b %), (4.29 ± 0.09a) and the number of ramuli (P1 = 56.2 ± 21.3a), (P2 = 19.5 ± 2.3b), (P3 = 46.3 ± 3.1a). The conclusion of this study each parameter (absolute weight, absolute length and number of ramuli) has a significant difference.

Abstract

Aquaculture is a food production sector that is developing quite rapidly in the world with a projection that production will double in the next 15-20 years. However, to run a cultivation system, you must have a large area of ​​land and large capital. The Covid-19 pandemic has had an impact on all aspects of people's lives. One of the aspects most affected by the pandemic is the economy, namely the occurrence of mass layoffs. Therefore, it is necessary to make alternative efforts that can help increase people's income during a pandemic, with a low risk of failure, and easy to implement as a side business during a pandemic. Budikdamber or also known as fish farming in buckets, can be an alternative business that can be done to maintain food security and increase income during a pandemic. Budikdamber is a form of fish farming that is inexpensive and easy to implement. The Budikdamber extension activity is one way to educate the community around Bolok Village, West Kupang, NTT. This PkM program was carried out with the output of the Budikdamber extension activity on November 9, 2020, attended by 56 participants from Bolok Village, West Kupang District, Kab. Kupang. The output of this program is that the people of Bolok Village are more educated about the easy and inexpensive practice of catfish farming in order to maintain independent food security in the midst of the Covid-19 pandemic and at the same time become an alternative solution for people's income, because they do not use large land and can take advantage of the yard. .

Abstract

Kotoran kelelawar mengandung banyak unsur hara yang tinggi (N, P, K, Ca, Mg, S), namun di sisi lain hasil buangan kelelawar ini mengandung C/N rasio yang rendah sehingga perlu dilakukan suatu proses untuk meningkatkan C/N rasio yang pada akhirnya dapat dimanfaatkan oleh tanaman. Penelitian ini bertujuan untuk mengetahui kadar nitrat dan fosfat pada pupuk guano serta pemanfaatannya untuk pertumbuhan anggur laut (Caulerpa racemose). Penelitian ini dilaksanakan pada bulan Oktober sampai November 2021 bertempat di Teaching Factory Budidaya, Politeknik Kelautan dan Perikanan Kupang, Nusa Tenggara Timur. Pembuatan pupuk guano dilakukan menggunakan kotoran kelelawar, EM4, gula merah, terasi, dan air tawar sebagai pelarut yang difermentasikan selama 12 hari dan dilakukan pengujian sampel setiap tiga hari sekali. Hasil penelitian menunjukkan bahwa kotoran kelelawar secara alami mengandung kadar fosfat dan nitrat berturut-turut sebesar 1,030 mg/L dan 2,308 mg/L. Kadar fosfat dan nitrat selama 12 hari fermentasi mengalami penurunan dan kenaikan dan diperoleh hasil kadar fosfat dan nitrat pada hari ke-12 sebesar 1,302 mg/L dan 2,296 mg/L. Peningkatan dan penurunan kadar fosfat dan nitrat berkaitan dengan aktivitas mikroorganisme yang terdapat di dalam EM4. Hasil penelitian menunjukkan bahwa pupuk guano mengandung kadar fosfat dan nitrat yang dapat dimanfaatkan sebagai sumber nutrisi bagi tanaman dan terbukti dapat meningkatkan pertumbuhan anggur laut (C. racemose) dengan menaikkan bobot anggur laut dan panjang serta jumlah ramuli. Pupuk guano yang diperoleh dapat dijadikan alternatif pengganti pupuk organik yang harganya relatif mahal di Kota Kupang.

Abstract

Assistance in the form of seeds and feed will become one of the programs of the Kupang City Maritime Affairs and Fisheries Department in 2022 to improve the economy of 56 catfish farmers. The purpose of the study was to analyze the impact of capital, human resources, and marketing on yield in catfish farming. The investigation was conducted in the city of Kupang for 120 days. Data was collected through observations, questionnaires, and interviews and analyzed for rank spearman correlation, multiple regression, and SWOT analysis. Capital, human resources, and marketing factors significantly affected catfish production in Kupang City, with Rank Spearman's correlation p-value (0.024?0.050), p-value (0.021?0.050), and p-value (0.000?0.050). 0.277, 0.283, and 0.548 were obtained. The direction of the influence relationship of capital, human resources, and marketing factors on production is positive, meaning that production increases as capital increases, and production increases as capital increases. Better human resources capabilities lead to higher productivity and vice versa. Every time there is a change in production inputs, such as capital and human resources (labor), it affects the production at the catfish farm in Kupang City. Development strategies are implemented through consulting and training, expanded access to capital and large-scale promotions.
