Abstract

During the COVID-19 pandemic, restrictions on activities directly affected people's lives socially and economically to meet their needs of people's lives, namely by developing aquaponic technology with a fish farming system in buckets (Budikdamber). These activities maximise limited land with various crops and develop fisheries so that the results can be used to meet household food needs independently. This service was conducted for local KKN students online through a zoom meeting on September 13, 2021, with 20 participants. The implementation of aquaponics system activities considers the types of fish and vegetables recommended and the procedures for making budikdamber.

Abstract

Pangasius catfish (Pangasius sp.) was an important commodity in Indonesia. High demand in the market requires production to be carried out actively. Adding spirulina as a supplement to feed was a way to increase the growth of pangasius catfish seeds for optimal production. The aimed of the research was to determine the effect of spirulina on the growth of pangasius catfish seeds which were added to pelleted feed. The research used a completely randomized design with four levels of treatment. Treatment 1 (100g commercial pellets + 3g spirulina), treatment 2 (100g commercial pellets + 5g spirulina), treatment 3 (100g commercial pellets + 7 g spirulina), treatment 4 (100g commercial pellets + 9g spirulina). The parameters observed were growth of length, weight, survival, and water quality (pH, temperature and dissolved oxygen). The study results showed that the addition of 7 g spirulina had the best effect on growth with a length of 5.25 cm and a weight of 6.74 g. Meanwhile, the lowest occurred when adding 9 g of spirulina with a length of 4.08 cm and a weight of 5.78 g. There was no mortality during maintenance so that the survival rate of pangasius catfish seeds was 100% in each treatment. So the addition of spirulina to feed has an effect on the growth of pangasius catfish. However, if ftoo much spirulina was added, the effect will not be optimal.

Abstract

The high market demand for gourami has led to an increase in fish farming activities. However, this fish farming activity is constrained by the spawning and breeding process. Gourami fish takes quite a long time in the seed growth phase so it is feared that it can hamper the fulfillment of gourami fish stocks in the market. Several studies have been conducted to shorten the growth time of fish seeds. One of them is in the field of feed. Modification and alternative feed are expected to contribute to science in the cultivation of gourami fish seeds. The purpose of this study was to determine the effect of feeding additives to increase the growth of carp fry (Osphoronemous gouramy). The research was conducted from August to October 2019 using nets in concrete ponds.  The research was conducted experimentally using the group randomized design (RAK) method carried out in 4 treatments and 4 groups. The treatments tested were the provision of additional ingredients consisting of P_1 = 15% Probiotic / Kg feed, P_2 = 0.4% Vitamin C / Kg feed, P_3 = 3% Spirulina/kg feed, P_4 = 3.25% Papain enzyme/kg feed. Observation parameters include absolute length growth, absolute weight growth, survival, and feed conversion ratio. The results showed that 3% spirulina/kg and 3.25% papain enzyme/kg had a significant effect on the rate of weight growth and growth.

Abstract

Silkworms (Tubifex sp) are a natural feed with high nutritional content and are needed by fish, especially in the fry phase to support fish growth. Therefore, knowledge of natural food cultivation is needed to support the success of fish farming. Silkworm cultivation requires media with high organic content. Tofu pulp waste is one of the media that can be utilized for silkworm cultivation.  The purpose of this activity is to increase community skills in silkworm cultivation by utilizing tofu pulp waste as a cultivation medium to provide natural feed for cultured fish carried out by the Bumdes fish farming group of Serdang Menang village, SP. Padang OKI. Padang OKI.  The method is carried out by conducting counseling and mentoring in making silkworm cultivation sites and how to cultivate silkworms. Community Service activities regarding the production of silkworm cultivation with a system of utilizing organic waste have been well understood by the community.  It is hoped that the community in Serdang Menang Village, SP. Padang Kab.OKI can apply it in fish farming activities.

Abstract

Utilization of seluang fish (Rasbora sp.) for food and collection by the community as decorative fish to serve as a source of income. The objective of research on the identification of plankton in the digestion of seluang fish from the Musi river downstream is to determine the type of plankton ingested by seluang fish, phytoplankton or zooplankton, which are seluang fish's natural food source. Prior to domestication, plankton variations can be exploited for cultivation efforts as a source of knowledge. The study was conducted in May, June and July 2019 at three stations. Samples of fish caught were observed in the Biology laboratory of the Faculty of Agriculture, University of Muhammadiyah Palembang. The fish is dissected using a scalpel, and its digestion is put in a small jar containing a 10% formalin solution. The fish digestion was formalized, transferred into a measuring cup with the addition of 10 ml of an aqueduct, stirred until crushed and observed under a microscope using a petri dish. The study results showed that the seluang fish species (Rasbora sp.) caught were Rasbora argyrotaenia and Rasbora borapetensis. In digestion, there are phytoplankton consisting of 4 classes, namely Cyanophycea, Chlorophyceae, Bacillariophyceae, and Eugleanophycea, while in zooplankton, only one class is found, namely Entomostraca. The composition of phytoplankton is greater than that of zooplankton of the class Cyanophyceae predominating by 34.7%. Thek-index of plankton diversity in digestion is moderate, the biota community is stable, and the dominance index indicates species dominate at each station. Water quality is relatively normal only at station 2, with the value of dissolved oxygen and low-value pH. The phytoplankton composition is greater than that of zooplankton.

Abstract

Research on Plankton Community in The Waters of Ogan River Kertapati District, Palembang, South Sumatra Province, has been conducted from March to April 2018. This study aimed to identify the plankton community, i.e., abundance, diversity index, dominance index, similarity index between stations, and describe pollution level conditions based on saprobic coefficient. Sampling in this study using purposive random sampling method at five observation stations with three sampling locations, respectively. The physical and chemical parameters of the waters include temperature, brightness, current speed, pH, Dissolved Oxygen (DO), nitrates, and phosphates. The composition of plankton consists of 47 Genera derived from 8 Classes, with a total abundance value in March ranging from 13-27 ind./L, and the total value of abundance in April 2018 has a range of values of 12-21 ind./L. Plankton diversity index values in about 1.87-2.98 indicate the stability of the moderate biota community. Based on the index of plankton dominance with a range of 0.05-0.21, no species dominate other species or D = 0(<0.5). In contrast, the index of plankton similarity between stations shows the communities between stations are relatively different (<50%). The water quality of the Ogan River based on saprobic coefficients is light to very light.

Abstract

Residents use the Komering tributary that flows through Pangkalan Gelebak Village in Banyuasin Regency for fish farming activities. Villagers tried to cultivate catfish and tilapia, but it did not work because they died. Water as a medium for fish farming activities is an important factor that must be considered. Water quality in waters can affect aquaculture activities and fish growth. The study was conducted to determine the water quality (physics and chemistry) in the Komering River tributary as a basis for the cultivation environment. The research was conducted in the Komering tributary of Pangkalan Gelebak Village, Banyuasin Regency,  in September, October, and November 2019. The sampling point is determined using a purposive sampling method in four sampling points. The temperature measurements range from 27-32.7ºC, depth 0.4-9 m, brightness 0.2-1.1 m, and turbidity 12.62-69.2 NTU. Only the depth of the four physical parameters is unsuitable for cultivation activities. During the dry season, the water depth between the riverbed and cage nets does not reach 1m. Chemical parameter measurement results; dissolved oxygen 1.7 – 7 mg/l, pH 6.5 – 7, alkalinity 34 - 46 mg/l CaCO3, nitrate 0.892 - 2.278 mg/l, nitrite 0.032 - 0.217 mg/l, ammonia 0.02-0.398 mg/ l and ortho-phosphate 0.054-0.283 mg/l. The value of nitrate, ammonia, and orthophosphate indicated high values so than unsuitable for fish farming activities. Agricultural activities around creeks and domestic waste disposal are causes of poor water quality.

Abstract

Research on the diversity of fish fauna has been widely carried out, especially in Indonesia, even in some areas has decreased, especially in rivers due to many factors. The Ogan River that flows through Ogan Ilir Regency is a multipurpose river for the community, not only for daily needs, transportation, aquaculture activities, and capture fisheries. Currently, information on fish fauna in the Ogan River in Ogan Ilir Regency has not been verified and has not been published in detail. The study aims to determine the types of fish caught, diversity index, uniformity index, abundance index, and dominance index. The research was conducted in the Ogan River, South Pemulutan Subdistrict, Ogan Ilir Regency with a survey method that determines the station point by purposive sampling and produces three stations with different characteristics. Sampling of fish was done 8 times for three months using a gill net. The results showed that in the Ogan River 24 species of fish were found with a total catch of 276 fish classified into 14 families, namely dukang fish, dukang yellow fish, long whiskers catfish, asian redtail catfish, marble goby, milkfish, duskyfin glassy perchlet, striped snakehead, nile tilapia, long tongue sole, silver barb, tinfoil barb, beardless barb, black sharkminnow, bonylip barb, umbut fish, sleepy goby, kissing gourami, amazon sailfin catfish, giant prawn, giant gourami, pangasius juaro, malayan leaffish, and lais fish. All stations show a moderate diversity index value of 1.72-2.842, the uniformity index value shows evenly distributed at all stations, namely 0.898 - 1.816, the abundance index value is 1 which indicates less abundant at all stations and the dominance index shows a low value that ranges from 0.068-0.094 or no dominating species.

Abstract

Belanti village used to be land before the entry of the palm oil company, which caused the canalization to form a lake or swamp. The company's canalization blocked the flow of a natural river in Ulak Pati, Pampangan sub-district, preventing water from flowing and causing it to pool in what was once open land. The result of this canalization caused changes to the ecosystem in the village of Rawa Belanti, which had an impact on the growth factors of aquatic organisms that formed along with the formation of the lake/swamp. This study focuses on collecting data and information about the growth of cork fish that are found in many communities in rawa belanti through the sampling method. The study was conducted for 4 months with sampling intervals every 10 days. Calculation of length-weight and condition factor used all cork fish caught during the sampling.The growth factors assessed were the correlation between length and weight, and the condition factor of the gourami fish caught in the swamp. Based on the results of the study, the correlation of length and weight growth is negative allometric, which means that weight growth is slower than the growth of fish length. Assessment of the condition factor of cork fish shows an average value of 1, which means that the fish is in good body condition. Water quality assessment was also conducted in order to support growth data.

Abstract

Environmental factors play an important role in the growth and survival of fish, both directly and indirectly. This role is not limited to determining the success of fish growth in terms of length and weight; fish behavior, feeding patterns, and metabolism are also affected. Photoperiod itself is defined as the length of time of light and dark exposure. This study aims to evaluate the effect of photoperiodism on the growth rate and physiological response of red tilapia (Oreochromis niloticus). The study was conducted in Gandus District, Palembang City. Data and analysis were performed using a completely randomized design (CRD) with several parameters such as growth rate, weight gain, survival rate, and behavior of red tilapia observed qualitatively in response to treatment with varying light exposure times. The treatments given were 3 variations of light and dark exposure and 5 repetitions with variations P1: 20 hours of light: 4 hours of dark (20T; 4G) P2: 16 hours of light: 8 hours of dark (16T; 8G), and P3: 12 hours light : 12 hours dark (12T; 12G). The analysis results showed that red tilapia had a positive growth response, characterized by an increase in fish length and weight, caused by increased metabolism due to an increase in feed consumption rate. Fish behavior changed compared to the control group due to physiological stress caused by prolonged exposure to light.
