Abstract

In fish farming activities, problems often arise that must be faced by farmers, the main factor causing the failure of fish farming efforts is the emergence of disease attacks. The type of disease that often attacks carp (Cyprinus carpio) is the bacteria Aeromonas hydrophila. Efforts made by farmers using artificial drugs or antibiotics. The use of antibiotics does not always have a positive effect; there are also negative effects. Therefore, natural, environmentally friendly handling is needed, and water lily leaf extract plants (Crinum asiaticum L.) are able to treat A. hyrophila infections in farmed fish. This study aims to determine the soaking of water lily leaf extract on the survival and optimal concentration that can reduce infection in carp juvenile (Cyprinus carpio). The research method used is an experiment with a Completely Randomized Design (CRD) consisting of 3 treatments and 3 replications. Treatment P1 (20 ml of water lily leaf extract), treatment P2 (40 ml of water lily leaf extract), and P3 (60 ml of water lily leaf extract). Data were analyzed using Analysis of Variance (ANOVA). If the results were significantly different, they were followed up with the Least Significant Difference (LSD) test. The results showed that the provision of water lily leaf extract (Crinum asiaticum L.) soaking had a very significant effect on the survival of carp (Cyprinus carpio) juvenile. The optimal concentration that can reduce A. hyrophila bacterial infection is in treatment P1 (20 ml) with the highest survival rate of 90%. Water quality during the study obtained a temperature value between 23-27.3 oC, pH between 6.9-8.45, and DO levels between 4.1-8.3 mg/l.

Abstract

Paddle aerator is an important tool in intensive shrimp farming. The purpose of this study is to determine the performance and electrical power consumption of paddle aerators based on the results of dynamic modelling analysis. This study uses causal ex-pose facto design concept with data analysis using dynamic modelling system. The results showed the salinity levels of pond 1 20-27 gr/L and pond 2 31-33 gr/L, pH pond 1 7.9-9.0 and pond 2 8.1-8.3, DO concentration pond 1 4.43-6.93 mg/L and pond 2 4.72-5.99 mg/L, temperature pond 1 27.15-31.400C with a brightness of 43 cm and pond 2 ranging from 27.50-29.850C with a brightness of 49 cm. From the calculation of the level of oxygen production paddle aerator power 1 HP produces oxygen average 2.12 mgO2 / hour (1.68-2.89 mgO2 / hour) with gas pressure 10.31-16.00 mmHg and paddle aerator power 2 HP produces oxygen average 3.20 mgO2 / hour (2.82-3.65 mgO2 / hour) with gas pressure 10.05-14.56 mmHg. From the accumulated results, the electrical load power required for pond 1 is about 6.83-10.38 kW and pond 2 is about 6.59-7.71 kW. The performance of 1 HP paddle aerator is more effective than 2 HP paddle aerator 4 pieces. The results of dynamic model analysis estimated the level of dissolved oxygen production by paddle aerators during one cultivation cycle ranged from 1-2.70 mgO2/hours and 1-2.75 mgO2/hours with a rotational speed of 0-30 rpm/s and power requirements of 8-10 kW. The conclusion from the results of this study is that the use of 1 HP paddle aerators in large quantities is proven to be more effective and based on the results of dynamic modelling system analysis, it is shown that the performance of DO production by paddle aerators will stagnate at week ten of the cultivation period, with increasing electrical power requirements.

Abstract

One of the determining factors the success of aquaculture is the provision of fish feed. There are many types of fish feed sold in the market, ranging from natural feed to artificial feed. One type of natural fish feed was Daphnia sp. Growth of Daphnia sp can be maximized by utilizing livestock waste as an additional nutrient. The aim of this community partnership program was to socialize to the public about Daphnia sp natural food and provide training to the community on how to cultivate Daphnia sp. The main target was an aquaculture stakeholder namely Women Farmers Group of Permai Tani which was in Gandusari Village, Bandongan District, Magelang Regency. The stages of this activity include tools and materials preparation, program of socialization to partners, implementation, and evaluation program. The working steps of implementing the activity were preparing the tools and materials needed including Daphnia sp seeds, livestock waste (goat manure, chicken manure and eggs) and catfish cultured wastewater as a culture medium. This activity has been carried out well, socialization and training attended by participants from Women Farmers Group of Permai Tani members. The enthusiasm of the participants was very good. This can be seen from sharing and asking activity about how to cultivate Daphnia sp. The results of this activity can increase the production of Daphnia sp which was used as natural fish feed in Gandusari Village, Bandongan District, Magelang Regency.

Abstract

This study's main focus is how the adaptation level affects the treatment of shelter composition in controlled containers. Parameters observed included growth rate, stress level, fish survival rate, and water quality during rearing. The research design used a completely randomized design (CRD) and was analyzed using SPSS. The results showed that the shelter composition was good for the C. limbata survival in experimental group 3 (P3) by placing the addition of sand, stones, gutters and aquatic plants in the aquarium. The effect of the composition of the shelter in a controlled container on the adaptation level of C. limbata was shown in experimental group 3 (P3), which experienced an increase in length of up to 5 mm, and an increase in weight of 25 g and a survival rate of 60%. This value is the best among 1st, 2nd, and control. This shows that the C. limbata can adapt its life to an artificial habitat that is as suitable as its natural habitat.

Abstract

Introduction: The availability of food sources influences the abundance of insect pollinators. The interaction between plants and insect pollinators is a symbiotic mutualism. In addition, the use of a plant barrier could attract insect pollinators in foraging activities. The study aimed to determine the effect of plant barrier on the abundance of insect pollinators and the yield of chili pepper. This research was carried out on agricultural land in Lumpoknyo village, North Luwuk, Banggai Regency, in July - December 2020. Methods: The research was carried out using a randomized block design, and four treatments, namely chili plants without barriers and covered with nets (P0 or control), eggplant plant barriers (P1), plant barriers with Zinnia sp and Cosmos caudatus (P2), and tomato plant barrier (P3). Observations were made every day at the time of flowering for 14 days. Sample collection of insect pollinators is done by taking insects that visit chili flowers using a sweep net. Results: Three species of insect pollinators were collected, namely Bembecinius sp, Ceratina sp, and Nomia sp. 730 individuals were found on eggplant barriers, 660 individuals on Zinnia sp and Cosmos caudatus barriers and 592 on tomato barriers. The highest individual is Ceratina sp (810 individuals), followed by Nomia sp. (799 individuals), and Bembecinius sp (373 individuals). Chili pepper cultivation using eggplant barrier yielded 4,93 kg/plot, Zinnia sp and Cosmos caudatus barriers 3,96 kg/plot, tomato barrier 3,62 kg/plot, and the lowest yield was shown in chili pepper fields covered with insect nets. of 2,00 kg/plot. Conclusion: The barrier system using eggplant is considered effective for increasing the abundance of insect pollinators and the yield of chili pepper.

Abstract

Vibrio sp. and plankton are important microorganisms in shrimp pond ecosystems. The research aims to predict the dynamics of Vibrio sp. and plankton abundance in intensive shrimp pond ecosystems based on causal model analysis. The research method used is an ex-pose facto causal design concept with quantitative descriptive data analysis using causal dynamic modeling. The results showed the water quality in the pond has a high correlation, except Vibrio sp. and alkalinity. In the pond ecosystem 24 genus of plankton from 6 classes. Chlorella sp. is the dominant plankton genus with an abundance of 1.00E+05-4.00E+05 cells/ml. Vibrio sp. abundance in ponds ranged from 1.38E+03 - 1.31E+05 CFU/ml. Based on the results of dynamic modelling, the growth pattern of Vibrio sp. lasted for 30 weeks which was divided into 4 growth phases. The conclusion of this study is that Vibrio sp. will dynamically experience a pure growth rate for 30 weeks with details of the initial growth phase (1-7 weeks), logarithmic growth phase (8-14 weeks), exponential phase (15-21 weeks), and growth declination phase (22-30 weeks). The growth phase of Vibrio sp. has a high degree of similarity to the growth pattern of plankton in the pond water ecosystem correlatively. The novelty of this research lies in the discovery of an estimation model for the abundance of Vibrio sp. and plankton during the shrimp farming cycle. This finding can serve as a fundamental reference for farmers to optimize feeding processes and conduct regular siphoning during the peak abundance of Vibrio sp. and plankton.

Abstract

Winged-bean meal can serve as a substitute for soybean meal in plant-based fish feed, despite its trypsin-inhibitor properties, which can be alleviated through heating processes. This study aimed to explore the potential of winged-bean meal subjected to different heating methods, namely oven (110 °C for 30 minutes) and autoclave (121 °C for 30 minutes), based on proximate analysis and trypsin activity. The study applied three treatments with four replications: oven heating (O), autoclave heating (A), and control (without heating, E). All data were analyzed using analysis of variance and Duncan’s multiple range test to determine the best treatment. Data were also compared to the nutrient requirements of several cultured freshwater fish in Indonesia. Heating treatments improved in vitro trypsin activity (1300 units/O and 1135 units/A vs. 835 units) but reduced protein (29.05±1.96%/A and 31.73±1.52%/O vs. 35.17±0.38%) and moisture contents. Additionally, the O treatment met the standards for aquafeed protein content (27-45%) and potentially fulfilled the protein requirements for catfish (25-40%), Nile tilapia (30-35%), and Java barb (30-32%). Therefore, oven heating presents a viable candidate as an alternative plant-based aquafeed ingredient. Nevertheless, the in vivo application of winged-bean meal as an aquafeed ingredient should be further evaluated to determine whether heating treatment effectively enhances digestive activity, nutrient retention, and growth performance in target fish species.

Abstract

Produksi ikan nila di Indonesia yang banyak diminati masyarakat luas menjadikan ikan nila mengalami peningkatan permintaan pasar. Namun, peningkatan target produksi komoditas ikan nila terdapat berbagai hambatan yang muncul seperti padat tebar tinggi, kualitas air yang buruk, dan timbulnya penyakit. Salah satu serangan penyakit yang ditemukan menyerang komoditas ikan air tawar, yaitu infeksi bakteri Aeromonas hydrophila. Penggunaan antibiotik yang diaplikasikan dalam jangka panjang dapat mengakibatkan dampak yang negatif bagi kesehatan ikan, sehingga perlu adanya alternatif bahan alami yang dapat diaplikasikan untuk pengendalian bakteri tanpa menimbulkan resistensi. Penelitian ini bertujuan untuk mengetahui pengaruh perendaman ekstrak rimpang bangle (Zingiber cassumunar Roxb.) terhadap kelulushidupan ikan nila (Oreochromis niloticus) yang diinfeksi bakteri Aeromonas hydrophila. Penelitian dilakukan selama 14 hari menggunakan Rancangan Acak Lengkap (RAL) dengan empat perlakuan dan empat ulangan. Perlakuan terdiri dari P1 (0 ml/L), P2 (0,25 ml/L), P3 (0,5 ml/L) dan P4 (0,75 ml/L). Parameter yang diamati meliputi kelulushidupan, gejala klinis, panjang bobot, dan kualitas air. Data kelulushidupan, panjang, dan berat dianalisis menggunakan Analysis of Variance (ANOVA) dan dilanjutkan dengan Duncan’s Multiple Range Test (DMRT). Data kelulushidupan dilakukan uji regresi polinomial. Data gejala klinis dan kualitas air dianalisis secara deskriptif. Hasil penelitian menunjukkan, bahwa perendaman ekstrak rimpang bangle berpengaruh nyata terhadap tingkat kelulushidupan ikan nila (P < 0,05), namun tidak berpengaruh terhadap panjang dan berat ikan nila. Gejala klinis yang muncul yaitu kemerahan, exopthalmia, sirip geripis, warna tubuh pucat disertai penurunan respons pakan dan perubahan tingkah laku ikan setelah infeksi bakteri. Penelitian ini menyimpulkan bahwa perendaman ekstrak rimpang bangle berpengaruh nyata terhadap kelulushidupan dengan nilai kelulushidupan tertinggi terdapat pada perlakuan P3 (0,5 ml/L) sebesar 77,5%.Kata kunci : Bangle; MAS; nila

Abstract

Male broodstock candidates of Asian redtail catfish tend to have aggressive behaviour due to excessive testosterone production, which is exacerbated by poorly-regulated high-cholesterol feeding practices. This study aimed to suppress these conditions by administering the dietary combination of animal and plant-based oils during pre-gonadal maturation of male broodstock candidates (BW: 215.83±41.28 g; BL: 272.12±19.89 mm), reared in a 2 × 1 × 1 m3 net cage with the stocking density of two fish per cage. This study was conducted using a completely randomized design with three dietary combination treatments (2% of each oil dosage) with four replicates: base feed with no mixed dietary oil (K), mixed fish oil-maggot oil (IM), and mixed fish oil-palm oil (IS). All parameters, namely reproductive performance (final length/Pt, final weight/Wt, feed intake/FI, gonadosomatic index/GSI, and hepatosomatic index/HSI) and blood chemistry profile (total cholesterol/TC, high-density lipoprotein/HDL, triglycerides/TG, and glucose/GLU), were statistically tested their significance using the analysis of variance and Duncan’s multiple range test with 95% confidence level. Significant differences were found in Pt and Wt (p<0.05), where the dietary combination of oils (IM-IS) showed higher Pt and Wt values than the dietary without the mixed oils (K). The IM treatment obtained the highest TG level (159.98±38.44 mg dL-1; p<0.05), yet showed no significant differences from the other treatments in TC, HDL, and GLU levels (p>0.05). This study concludes that the dietary combination of fish oil (2%)-maggot oil (2%) improves lipid deposition during pre-gonadal maturation and regulates energy storage through weight gain, without jeopardizing the somatic growth (length) of male Asian redtail catfish broodstock candidates.Calon induk ikan baung jantan memiliki sifat agresif yang salah satunya disebabkan produksi testosteron berlebih akibat pemberian pakan dengan kadar tinggi kolesterol. Penelitian ini ditujukan untuk mengurangi dampak tersebut melalui evaluasi kombinasi minyak hewani dan nabati pada pakan selama fase awal kematangan gonad calon induk ikan baung jantan (BW: 215,83±41,28 g; BL: 272,12±19,89 mm), yang dipelihara pada hapa ukuran 2 × 1 × 1 m3 dan padat tebar sebesar dua ekor ikan per hapa. Penelitian ini menggunakan rancangan acak lengkap dengan tiga perlakuan pakan kombinasi (dosis tiap minyak 2%) dan empat ulangan, yaitu pakan tanpa kombinasi (K), pakan dengan kombinasi minyak ikan-maggot (IM), dan minyak ikan-sawit (IS). Seluruh parameter, yaitu kinerja reproduksi (panjang akhir/Pt, bobot akhir/Wt, total konsumsi pakan/FI, indeks somatik gonad /GSI, dan indeks somatik hati /HSI) dan profil kimia darah (total kolesterol/TC, high-density lipoprotein/HDL, trigliserida/TG, dan glukosa/GLU), dianalisis menggunakan analisis sidik ragam dan uji jarak berganda Duncan dengan derajat kepercayaan 95%. Perbedaan nyata ditunjukkan pada Pt dan Wt (p<0,05), dimana kombinasi minyak IM-IS menunjukkan nilai Pt dan Wt yang lebih tinggi dibandingkan tanpa pemberian kombinasi minyak (K). Perlakuan IM memperoleh konsentrasi TG tertinggi (159,98±38,44 mg dL-1; p<0,05), namun menunjukkan tidak adanya perbedaan nyata terhadap perlakuan lainnya pada konsentrasi TC, HDL, dan GLU. Penelitian ini menyimpulkan, bahwa kombinasi minyak ikan (2%) dan minyak maggot (2%) mampu memperbaiki penyimpanan lemak untuk fase awal kematangan gonad (trigliserida dalam serum darah) dan mendorong penyimpanan energi melalui peningkatan bobot, tanpa mengganggu pertumbuhan somatik (panjang) dari calon induk ikan baung jantan.
