Catfish is one of the freshwater fish whose demand is increasing every year, both in the form of fresh fish and processed foods. This increase in demand along with the ease of maintenance has made catfish a cultivated commodity that is widely eyed by fish farmers. One of the important aspects in fish farming is the provision of fish feed, although it is relatively easy, but feed management is needed to increase fish production targets. The fish feeding method mostly uses manual sowing on the surface of the pond. This method has weaknesses in terms of labor requirements and the time required if catfish farmers have many ponds, especially if the breeders forget the schedule for fish feeding. The method of implementing this community service consists of socializing activities, presenting material, directing the steps for making automatic fish feeding tools, tool making practices, tool testing and evaluation. The manufacture of this automatic fish feed tool generally consists of making the body of the tool and the assembly of the timer module components. This activity was attended by 20 people who are members of the SYSGA group in Sumbersari District, a community group engaged in catfish farming. The activity went smoothly, the participants seemed enthusiastic during the activity. Further monitoring is needed to determine the level of effectiveness and efficiency of catfish production by breeders after the use of automatic fish feed equipment.

The article presents the results of an experiment to assess the effect of feed additive of humates on the growth rate and survival of different age groups of sterlet (Acipenser ruthenus L., 1758) and the conversion of fish feed for keeping in aquaculture. Based on the analysis of sources of scientific and technical information, it was found that humic drugs have long been used in crop production as growth stimulants and microfertilizers, and in animal husbandry - to normalize metabolism, treatment of digestive diseases and general stimulating effect on the body as a whole. Analysis of data on the use of humates in aquaculture indicated the presence of a positive effect of these compounds on individual cultivation objects. The small amount of information on the use of humates in fish farming has led to the conclusion that this direction of fish farming intensification is still insufficiently studied, and that studies of the impact of humic substances on aquaculture objects are not comprehensive and mainly concern the assessment of individual effects of biologically active action of the compounds on fish. The available information gave grounds to speculate about the prospects for the use of humates in sturgeon farming. To test this assumption, a series of experiments was conducted on the feeding of sterlet feed with the addition of sodium humate. The research was conducted in 2018, 2020 and 2021, in the production conditions of the cage fishery, located on the Kaniv Reservoir. The effect of different concentrations of sodium humate feed additives on one- and two year old sterlet was evaluated. It was found that the addition of sodium humate to fish feed in concentrations of 60, 100, 120 and 200 mg / kg of feed did not significantly affect the growth rate of sterlet. Thus, the advantage of experimental variants over the control for this indicator was insignificant, in the range of 1.0-1.6%. The effect of sodium humate on the survival of this year sterlet, for their cultivation in gardens. At the same time, the best, by 6.7-17.4%, feed conversion with the addition of humates by one- and two-year-old sterlet was noted. According to the results of the experiments, the best result was obtained in the variant using a feed additive of humates at a concentration of 200 mg / kg of feed. It is considered promising to continue the study of the impact of feed additives of humates on the growth and survival of valuable aquaculture objects under different housing conditions, in particular in closed recirculation aquasystems (RAS), as well as finding the optimal concentration of these additives in feed for different species and age groups of fish.

UKM Mandiri Jaya is a community group effort that has not been economically productive, but has a strong desire to become an entrepreneur. Members of these SMEs are made up of economically weak communities. They have a very low income. Daily necessities of life are obtained through farming and catfish farming. The effort is carried out on arable land and the home page. Agricultural products are sold, but are not able to meet the increasing needs. Catfish farming is also carried out on a small scale because it is constrained by the high price of feed on the market. With the aim to develop the business of fish farming, SMEs have been given fish seeds, materials and pellet making equipment and fish feed making machines. A fish feed machine is needed so that farmers can increase their income by utilizing existing ingredients as a fish feed composition. Partners have been trained so as to be able to make their own fish feed from quality ingredients and partners have the ability to use the machines provided. Through the feed produced by the use of a given machine, the better fish growth. More fish yields resulting in an increase in income for these partners.

Southeast Minahasa Regency has potential natural resources, one of them related aquculture in Lake Tutud. Considering the conditions and opportunities for the development of aquaculture in Lake Tutud, improvement efforts and increase the potential for fish production needs to be done. Some of the factors that caused the current problems include declining water level of Lake Tutud drastically in recent years caused by the death of most of spring water coming into the lake causing sedimentation, high content of sulfur from the irrigation run off. All of these problems can be a barrier to tilapia fish culture, so it is necessary to periodically measure the water quality in Lake Tutud in order to improve and enhance the quality of the water before it is used for culture efforts. Referring to the current economic conditions of the community around Lake Tutud of Tombatu 3 Village include community leaders and the fish farmers are also public observers who are interested in this program, through the Program Implementation of science and technology for the Community (IbM) of PNBP UNSRAT given counseling, training and mentoring such as water quality management technology. The methods used in the implementation of science and technology program are education, training, discussion and mentoring. Materials used were proper method of producing fish seeds, the stages of the production process, the use immunostimulatory in fish feed for fish disease management, maintain and improve water quality. With the Community Service Program through the application of science and technology, it is expected that there will be a transferred in science and technology in water quality management of Tutud lake so hopefully their business development, creation of business opportunity, income generation and welfare of the people in this Tombatu 3 village. The results revealed that the implementation of this community service activity in the form of the application of science and technology are: lecture activities, training, discussion and question and answer, including the lake water quality measurements that have been going well with good response of the fish farmers indicated by the presence of participants as much as 80%, show that a). increased production of tilapia fish farmers through water quality management can be implemented, b). tilapia fish farming is feasible and can provide profit if done properly, so it can be an alternative in an effort to help the reduction of unemployment and poverty. Interaction with the community on this community service activity, it is found that there were many people who still do not understand much about the overall material included engineering, water quality management and proper fish feed and feeding method. One of the barriers was the language, so it is necessary for the lectures and trainers to use the local language. It can be recommended in the future to keep on doing this kind of community service considering the inherent of the knowledge and application of water quality management is still a new thing and has a business prospective opportunities in the Tombatu 3 village. Keywords: water quality, community, management. Abstrak Kabupaten Minahasa Tenggara mempunyai potensi sumber daya alam yang banyak salah satunya yang berkaitan dengan bidang Perikanan budi daya air tawar adalah Danau Tutud. Memperhatikan kondisi dan peluang pengembangan pembudidayaan ikan di Danau Tutud maka upaya perbaikan dan peningkatan potensi produksi ikan perlu dilakukan. Budi daya ikan khususnya di Danau Tutud adalah pembudidayaan pembesaran ikan nila di Keramba Jaring Tanjap (KJT). Dalam usaha pengembangan budi daya ikan air tawar harus diimbangi dengan pengelolaan kualitas air danau dan penanganan penyakit ikan yang baik. Oleh sebab itu aspek-aspek yang menjadi factor pembatas dalam hal peningkatan produksi perlu dicari jalan keluarnya yang baik. Beberapa faktor yang menjadi masalah yang dihadapi saat ini antara lain adalah menyusutnya secara drastis permukaan air Danau Tutud dalam beberapa tahun belakangan ini akibat dari matinya sebagian besar mata air yang masuk ke danau sehingga mengalami sedimentasi, selain itu kandungan sulfur atau belerang cukup tinggi dari air irigasi yang berasal dari danau yang mana akan dapat menjadi hambatan usaha pembenihan ikan nila, sehinggan diperlukan adanya pengukuran kualitas air Danau Tutud untuk dapat memperbaiki dan meningkatkan kualitas air sebelum dipergunakan untuk usaha budi daya. Mengacu pada kondisi tersebut maka untuk masyarakat sekitar Danau Tutud di Desa Tombatu 3 antara lain para tokoh masyarakat dan para pembudidaya ikan juga masyarakat pemerhati yang tertarik pada program ini, melalui Program Penerapan Ipteks bagi Masyarakat (IbM) dari PNBP UNSRAT diberikan penyuluhan, pelatihan dan pendampingan berupa teknologi pengelolaan kualitas air. Metode yang digunakan dalam Program Penerapan Ipteks ini adalah penyuluhan, pelatihan, diskusi dan pendampingan. Materi kegiatan pengabdian penerapan Ipteks ini meliputi cara memproduksi benih ikan yang benar dan baik, tahapan-tahapan proses produksi pakan ikan yang diberi imunostimulan untuk penanganan penyakit ikan, tahapan tahapan untuk memelihara dan meningkatkan kualitas air. Dengan Program Pengabdian Kepada Masyarakat melalui penerapan Ipteks ini diharapkan dapat ditransfer ilmu dan teknologi pengelolaan kualitas air Danau Tutud sehingga diharapkan adanya pengembangan usaha, penciptaan peluang berusaha, peningkatan pendapatan dan kesejahteraan masyarakat di Desa Tombatu 3 ini. Hasil pelaksanaan kegiatan pengabdian kepada masyarakat dalam bentuk penerapan ipteks ini adalah: kegiatan ceramah, pelatihan, diskusi dan tanya jawab, termasuk dengan pengukuran kualitas air Danau Tutud telah berjalan dengan baik respon kehadiran peserta sebanyak 80%. Dari hasil pelatihan, diskusi tanya jawab dan prakek dilapangan menunjukkan bahwa a). peningkatan produksi pembudidaya ikan nila melalui pengelolaan kualitas air ini dapat dilaksanakan, b). pembudidayaan ikan nila ini layak dan dapat memberikan profit bila dilaksanakan dengan baik dan benar, sehingga dapat menjadi alternatif lapangan usaha baru untuk membantu program pengentasan penggangguran dan penanggulangan kemiskinan. Dari hasil interaksi dengan masyarakat pada kegiatan pengabdian ini diketahui bahwa banyak masyarakat yang masih belum banyak mengerti tentang keseluruhan materi termasuk pada materi teknik dan proses pengelolaan kualitas air dan pakan ikan yang baik dan benar, salah satu kendala adalah bahasa, sehingga perlu ceramah dan pelatihan yang menggunakan bahasa setempat. Untuk selanjutnya dapat direkomendasikan agar terus digalakkan dan dilakukan pembinaan yang melekat mengingat pengetahuan dan penerapan pengelolaan kualitas air ini masih merupakan hal yang baru dan merupakan peluang usaha yang prospektif di Desa Tombatu 3. Keywords: Kualitas Perairan, Komunitas, Manajemen.

Abstract In this study, daidzein long-circulating liposomes (DLCL) were prepared using the ultrasonication and lipid film-hydration method. The optimized preparation conditions by the orthogonal design was as follows: 55 to 40 for the molar ratio of soybean phosphatidylcholine (SPC) to cholesterol, 1 to 10 for the mass ratio of daidzein to total lipid (SPC and cholesterol) (w:w), the indicated concentration of 5% DSPE-mPEG2000 (w:w), 50 °C for the hydration temperature, and 24 min for the ultrasonic time. Under these conditions, the encapsulation efficiency and drug loading of DLCL were 85.3 ± 3.6% and 8.2 ± 1.4%, respectively. The complete release times of DLCL in the medium of pH 1.2 and pH 6.9 increased by four- and twofold of that of free drugs, respectively. After rats were orally administered, a single dose of daidzein (30 mg/kg) and DLCL (containing equal dose of daidzein), respectively, and the MRT0−t (mean residence time, which is the time required for the elimination of 63.2% of drug in the body), t1/2 (the elimination half-life, which is the time required to halve the plasma drug concentration of the terminal phase), and AUC0−t (the area under the plasma drug concentration-time curve, which represents the total absorption after a single dose and reflects the drug absorption degree) of daidzein in DLCL group, increased by 1.6-, 1.8- and 2.5-fold as compared with those in the free group daidzein. Our results indicated that DLCL could not only reduce the first-pass effect of daidzein to promote its oral absorption, but also prolong its mean resident time to achieve the slow-release effect.

The purpose of this study is to compare and analyze the kinematic characteristics of the upper limb segments during the archery shooting of Paralympic Wheelchair Class archers (ARW2—second wheelchair class—paraplegia or comparable disability) and Paralympic Standing Class archers (ARST—standing archery class—loss of 25 points in the upper limbs or lower limbs), where archers are classified according to their disability grade among elite disabled archers. The participants of this study were selected as seven elite athletes with disabilities by the ARW2 (n = 4) and ARST (n = 3). The analysis variables were (1) the time required for each phase, (2) the angle of inclination of the body center, (3) the change of trajectory of body center, and (4) the change of the movement trajectory of the bow center by phase when performing six shots in total. The ARW2 group (drawing phase; M = 2.228 s, p < 0.05, holding phase; M = 4.414 s, p < 0.05) showed a longer time than the ARST group (drawing phase; M = 0.985 s, holding phase; M = 3.042 s), and the angle of the body did not show a significant difference between the two groups. Additionally, in the direction of the anteroposterior axis in the drawing phase, the change in the movement trajectory of the body center showed a more significant amount of change in the ARW2 group than in the ARST group, and the change in the movement trajectory of the bow center did not show a significant difference between the two groups.

Feed is one of the most important external signals in fish that stimulates its feeding behavior and growth. The intake of feed is the main factor determining efficiency and cost, maximizing production efficiency in a fish farming firm. The physiological mechanism regulating food intake lies between an intricate connection linking central and peripheral signals that are unified in the hypothalamus consequently responding to the release of appetite-regulating genes that eventually induce or hinder appetite, such as apelin; a recently discovered peptide produced by several tissues with diverse physiological actions mediated by its receptor, such as feed regulation. Extrinsic factors have a great influence on food intake and feeding behavior in fish. Under these factors, feeding in fish is decontrolled and the appetite indicators in the brain do not function appropriately thus, in controlling conditions which result in the fluctuations in the expression of these appetite-relating genes, which in turn decrease food consumption. Here, we examine the research advancements in fish feeding behavior regarding dietary selection and preference and identify some key external influences on feed intake and feeding behavior. Also, we present summaries of the results of research findings on apelin as an appetite-regulating hormone in fish. We also identified gaps in knowledge and directions for future research to fully ascertain the functional importance of apelin in fish.

Abstract Fish bone is a solid waste that usually found in traditional fish markets of Ternate. The bone fraction contains high minerals such as calcium, phosphorus, and collagen proteins which are important for fish growth. Tuna fish bone waste was processed into dry fish feed and mixed into feed formulation of Tilapia. Four different dose of tuna fish bone powder were applied namely 0%, 1%, 3%, and 5% as mentioned treatment A, B, C, and D. Fish diet were given to Tilapia juvenile for 42 days. Results show that the body weight and specific growth rate are highest in fish which given 3% dose of tuna fish bone than other treatments. It reaches 38.66 g and 9.617% BW/day. The lowest FCR is 1.34 in treatment C and the survival rate is not significantly different among treatments (p>0.05).

Fish contain many nutrients that are very beneficial for the body, but often fish are traded in a state of death as well as being alive. To observe the freshness of tilapia is done by the introduction of color changes that appear on digital images using the least squares method. The purpose of this research is to build an image management application system to detect the freshness of tilapia. The data used are 10 samples of tilapia images which are photographed every 1 hour for 15 hours and obtained 150 image data and then processed and analyzed using the least squares method. The first process begins with image processing by cropping at the edge of the eye of the original image and then proceed with resizing to 1000 x 1000 pixels and changing the image format to *. Png. After the image has been processed then the average value is calculated rata grayscale uses the 'rata_rata Gambar' application system and an equation is stored which is stored as training data on the application system. After the image has been processed then the image is input into the system, the image will be converted into grayscale form and displayed at a predetermined place together with the rgb and grayscale histograms and then calculated using the least squares method. The last process we do is matching the test image with the image stored as training data and we conclude whether the image is (very fresh, fresh, fresh enough, not fresh, or very not fresh), the percentage of freshness of the anchor fish, and the length of time the anchor fish dies. This study used 150 samples of fish images from fresh fish that were still very fresh until the fish were not very fresh (rotten).

Drug delivery constitutes the formulations, technologies, and systems for the transport of pharmaceutical compounds to specific areas in the body to exert safe therapeutic effects. The main criteria for selecting the correct medium for drug delivery are the quantity of the drug being carried and the amount of time required to release the drug. Hence, this research aimed to improve the aforementioned criteria by synthesizing a medium based on calcium carbonate-nanocellulose composite and evaluating its efficiency as a medium for drug delivery. Specifically, the efficiency was assessed in terms of the rates of uptake and release of 5-fluorouracil. Through the evaluation of the morphological and chemical properties of the synthesized composite, the established 3D printing profiles of nanocellulose and CaCO3 took place following the layer-by-layer films. The 3D printed double laminated CaCO3-nanocellulose managed to release the 5-fluorouracil as an effective single composition and in a time-controlled manner.
