Abstract

Maggot or fly larva black soldier fly (Hermetically illucens) has been widely reported to be able to improve the growth performance of farmed fish because it contains high protein. Adding microalgae Aurantiochytrium sp. which contains omega-3 docosahexanoic acid (DHA) enriches the quality of fish feed. This research used a Completely Randomized Design (CRD) consisting of six treatments, each consisting of four repetitions with the percentage of maggot and microalgae. Aurantiochytrium sp. different ones. Then the ANOVA test was continued after fulfilling the requirements for normality and homogeneity of the data, then the Least Significant Difference (BNT) Follow-up Test was carried out. All parameters of absolute weight, relative weight, absolute length, relative length have value F>F table. The optimum animal feed formulation resulting from this research was obtained in P3 treatment with a composition of Corn Flour + Bran 59%, Maggot 30%, Aurantiochytrium,sp 11%. Providing variations in maggot composition black soldier fly (Hermetically shining) and micro algae Aurantiochytrium sp affects the growth of catfish (Clarias, Sp.). It is hoped that the results of this research will become fish animal feed that produces protein and omega 3 DHA content in fish as a source of quality animal protein for humans.

Abstract

The growing demand for sustainable and high-quality animal feed has led to exploring alternative sources of protein and other essential nutrients. The black soldier fly (BSF) maggots Hermetia illucens and microalgae Aurantiochytrium sp. are promising candidates. Both have shown significant potential due to their nutritional profiles and environmental benefits. This study aimed to compare the fatty acid content of two groups of Sangkuriang catfish. One group was given commercial animal feed, while the other group was fed with a combination of Aurantiochytrium sp. microalga biomass feed, Hermetia illucens maggot, rice bran, and corn flour. The catfish fed with Aurantiochytrium sp. microalga biomass, Hermetia illucens maggot, rice bran, and corn flour had a different fatty acid composition than the control group. This alternative diet led to an increase in the omega-3 docosahexaenoic fatty acid (DHA) content in the catfish. The study results suggest that fish feed containing Hermetia illucens maggots and microalgae Aurantiochytrium sp. can enhance fish's beneficial nutrition after being fed this particular feed mixture.

Abstract

Chicken is the most consumed food commodity in Indonesia. Chicken also contains protein which is needed by the body to maintain body strength. However, due to the Covid-19 pandemic, chicken prices have soared due to the increasingly expensive feed prices along with the increase in demand for chicken in the market. This study aims to determine the effectiveness of feeding Maggot Hermetia illucens and Microalgae Aurantiocyhtrium sp. as a source of protein and fatty acids in Joper chickens (Gallus domesticus). Using a completely randomized design (CRD) consisting of 6 treatments and 4 repetitions. Treatment P0 (100% Bran, Corn, Pur feed), P1 (Maggot 30%, microalgae Aurantiochytrium sp. 1.5%, Bran, Corn, Pur 68.5%), P2 (Maggot 35% and microalgae Aurantiochytrium sp. 2%, Bran, Maize, Pur 63%), P3 (Maggot 40% and microalgae Aurantiochytrium sp. 2.5%, Bran, Maize, Pur 57.5%), P4 (Maggot 45% and microalgae Aurantiochytrium sp. 3%, Bran, Maize, Pur 52%), P5 (Maggot 50% and microalgae Aurantiochytrium sp. 3.5%). Parameters observed were final body weight and daily weight gain rate of joper chickens. The results of this study showed that the provision of P5 treatment gave the best results in increasing protein and omega-3 levels with results of 18.19% and 4.53% respectively compared to the protein and omega-3 content of the control treatment which only amounted to 16.62% and 1.17% respectively. This study provides results with treatment P5 which has a major effect on the growth of joper chicken (Gallus domesticus). The results of this study can be an option for chicken feed because it is proven to increase protein and omega-3 content in chickens.

Abstract

Raja Ampat (Southwest Papua Province) and Kepulauan Seribu (Jakarta Raya Province) are part of Indonesia#39;s territory, which includes the mangrove forest area. This habitat supports a diverse array of animals, plants, and microalgae, including Aurantiochytrium sp. It has antioxidant activity related to lipid content. This study aims to identify the lipid content and the antioxidant effects of the microalgae Aurantiochytrium sp.’s extract isolated from the mangrove forest areas of Raja Ampat and Kepulauan Seribu. The extraction process was conducted using the Folch method, which involves a 2:1 (v/v) chloroform-methanol solvent ratio. The microalgae Aurantiochytrium sp. extract of Raja Ampat (MAERA) and microalgae Aurantiochytrium sp. extract of Kepulauan Seribu (MAEKS) were analyzed using GC-MS, antioxidant potential tested in silico by target proteins (5ZLG, 2A1X, 3VLN, and 1EEM) using Autodock Tools, and in vitro by DPPH and ABTS radicals and the carotenoid bleaching method. The results showed that total squalene and fatty acids in MAERA and MAEKS were at different levels. Squalene as a ligand had the lowest binding energy (-9.4, -6.6, -7.7, and -6.5) compared to the native ligand (-5.6, -4.4, -5.2, and -5.2) and ascorbic acid (-5.6, -4.8, -5.3, and -4.9) by in silico antioxidant activity. The in vitro antioxidant activities by DPPH, ABTS, and ß-caroteen bleaching were 103.00 ± 3.75, 216.39 ± 367, 214.62 ± 7,07 (MAERA); and 131.85 ± 23.48, 225.50 ± 3.36, 251.69 ± 5.39 (MAEKS) were not significantly different (pgt;0.05) by all methods. These findings showed that the Aurantiochytrium sp. strains Raja Ampat and Kepulauan Seribu contained diverse levels of fatty acids and squalene. In the in silico study, squalene was evaluated and in vitro, the MAERA and MAEKS extracts showed moderate antioxidant activity.

Abstract

Aurantiochytrium microalgae has long been recognized as oleaginous microalgae since its capability to produce high content of lipids biomass. Produced lipids from cultivation process of Aurantiochytrium can contain high concentration of omega-3 docosahexanoic acid, hence valuable biomass from the Aurantiochytrium microalgae has the potential to be used as a source of raw materials for nutrition, cosmetics and medicines. Generally,  Aurantiochytrium microalgae can be found in mangrove ecosystems. Even Indonesia is ranked as the largest mangrove in the world, but the use of Aurantiochytrium sp microalgae is rarely explored in Indonesia. In order to optimize biomass utiisation produced the cultivation process, there shall be an optimum extraction process. Therefore, this study present the optimization of lipids from the Aurantiochytrium sp microalgae. The isolate used in this research comes from Bunaken mangrove forest, North Sulawesi, Indonesia. The cultivation process consists of three steps, namely standing culture (SC, 48 hours), pre-culture (PC, 48 hours) and standing culture (SC, 120 hours). The cultivation took pace in an erlemeyer flask using orbital shaker with an orbital speed of 220 rpm at room temperature and pressure. The average dried biomass was 9.4 g/L. In addition to cultivation process, recent paper presents also an extraction methodology using organic solvents, namely methanol, chloroform, acetone, ethyl acetate, and n-hexane. The lipids fcation can be extracted with a minimum of 7% lipid and a  maximum of 47% lipid. From this study, extraction using acetone-chloroform-ethyl acetate solvents resulted in the highest fraction of lipids from the extraction process of Aurantiochytrium biomass. Since the paper discussing the extraction process of native Indonesia strain of Aurantiochytrium microalgae has never been presented before, therefore this paper shall be valuable basis for further research in this field.

Abstract

Aurantiochytrium microalgae is recognized as heterotrophic microalgae enables to produce high economic value of lipids for the use in health care industries. This research presents the production of biomass containing lipids through the bioconversion of fruit waste using Aurantiochytrium microalgae. Aurantiochytrium microalgae isolate was obtained from isolated mangrove leaves in the mangrove forest of Bunyu Island, North Kalimantan. The production process takes place in three stages, namely standing culture (SC), pre-culture (PC), and main culture. The SC and PC stages took place 48 hours respectively, while the MC took place 120 hours. The source of nutrition at the main cultivation stage (MC) used monosodium glutamate (MSG) as a nitrogen source, while the carbon source was from fruit waste. Amount of 250 grams of fruit waste was mixed and blended, added with 250 ml of water and then sonicated. The mass ratio of nitrogen source and carbon source was 1:3. The maximum of observed microalgal cell diameters for each stage were 14.5 μm (SC), 19.2 μm (PC) and 25.5 μm (MC). Produced biomass in this experiment has the characteristics of a yellow emulsion liquid, pH 6.2, fishy smell and total dissolved solids (TDS) of 4,820 ppm and a wet biomass of 68 g/l

Abstract

Thrautochytrids are often called heterotrophic microalgae that have a lot of omega-3 docosahexaenoic acid, or DHA. These microbes are found in many mangrove forest areas, including Indonesia, which has the biggest mangrove forests in the world. Indonesia is also beginning to look for useful microbes in these environments. The goal of this study was to find and identify a type of Thrautochytrid called Aurantiochytrium sp. in the mangrove forests of Tidung Island, part of the Thousand Islands near Jakarta. This area has never been studied for this type of microbe before. The study found two isolates of Thrautochytrids, named Aurantiochytrium sp. PTD5 and PTD6. These were identified by looking at the phylogenetic tree made from 18S rRNA sequences. The phylogenetic tree shows that PTD5 and PTD6 are closely related to other Aurantiochytrium strains like SR21 and BL10, which are widely used in research for making omega-3 DHA lipids.

Abstract

Abstrak: Masyarakat pulau Pari sudah tidak lagi membudidayakan rumput laut karena keadaan perairan yang semakin tidak kondusif. Alternatifnya, masyarakat saat ini menekuni pariwisata dan penginapan di pulau Pari. Salah satu keanekaragaman hayati yang terdapat di pulau Pari dan kurang disadari adalah kelimpahan dan potensi mikroalga. Masyarakat belum menyadari bahwa di pulau Pari terdapat mikroalga yang bernilai ekonomi tinggi yang memerlukan terobosan dalam pemanfaatannya dan juga pelestarian ekosistemnya. Pemandu wisata yang menjadi bagian dari masyarakat pulau diharapkan dapat mengedukasi jenis mikroalga dan manfaatnya terhadap warga lainnya maupun pengunjung pulau. Kegiatan pengabdian ini dilakukan dengan sosialisasi pemberian materi tentang mikroalga terhadap 21 warga pemandu wisata yang tergabung dalam ikatan Karang Taruna Unit 04 di Pulau Pari Kepulauan Seribu. Kegiatan diawali dengan pemberian soal pretest dan diakhiri dengan pemberian soal posttest. Perbedaan hasil dari skor yang diperoleh menjadi acuan dalam menentukan ada atau tidak adanya peningkatan pemahaman terhadap mikroalga ini. Angket pendapat diberikan demi mengevaluasi kegiatan untuk perbaikan ke depannya. Skor pretest yang diperoleh adalah 14,29 sedangkan posttest 20,95. Dengan demikian telah terjadi peningkatan pemahaman terhadap mikroalga. Harapannya dengan warga pemandu wisata yang memiliki wawasan terhadap mikroalga ini dapat mengedukasi masyarakat, wisatawan, dan pengunjung di pulau Pari akan pentingnya pelestarian perairan dan hutan mangrove sebagai habitat mikroalga serta membuka potensi peluang dalam mengembangkan produk berbahan dasar dari mikroalga.Abstract: The people of Pari Island are no longer cultivating seaweed due to increasingly unfavorable water conditions. As an alternative, people are currently pursuing tourism and lodging on Pari Island. One of the biodiversity found on Pari Island which is not recognized is the abundance and potential of microalgae. The community does not yet realize that on Pari Island there are microalgae that have high economic value which require a breakthrough in their utilization and also the preservation of their ecosystem. Tour guides, who are part of the island community, are expected to educate other residents and visitors about microalgae and their benefits. This community service activity involved providing outreach and training on microalgae to 21 tour guides from the Karang Taruna Unit 04 association on Pari Island, Seribu Islands. The activity begins with giving pretest questions and ends with giving posttest questions. The difference in the results of the scores obtained becomes a reference in determining whether or not there is an increase in understanding of this microalgae. Opinion questionnaires were given to evaluate activities for future improvement. The pretest score obtained was 14.29 while the posttest was 20.95. Thus there has been an increase in understanding of microalgae. The hope is that tour guides who have insight into microalgae can educate the public, tourists, and visitors on Pari Island about the importance of conserving waters and mangrove forests as microalgae habitats and open up potential opportunities in developing products made from microalgae.
