    Kegiatan pembesaran kepiting bakau hasil pembenihan di tambak masih terbatas dan pada umumnya masih merupakan kegiatan penelitian. Tujuan penelitian ini adalah untuk mengetahui pertumbuhan, sintasan, produksi, dan membuat analisis usaha pembesaran krablet kepiting bakau hasil pembenihan pada beberapa lokasi tambak tradisional. Penelitian dilakukan di tiga lokasi tambak yaitu Maros, Pangkep, dan Polewali Mandar (Polman). Tambak yang digunakan pada setiap lokasi merupakan tambak tradisional berkonstruksi tanah dengan sistem penggantian air berdasarkan pasang surut. Krablet kepiting bakau dengan kisaran bobot 0,05-0,1 g/ekor ditebar dengan kepadatan 0,24 ekor/m2 dan 0,27 ekor/m2 untuk Kabupaten Pangkep dan Polman secara berurutan sedangkan pada Kabupaten Maros dengan kepadatan 0,53 ekor/m2. Jenis pakan yang diberikan yaitu ikan rucah atau ikan liar yang ada di sekitar lokasi tambak dengan dosis 5%-10% dari biomassa dan diberikan dua atau tiga hari sekali. Hasil penelitian menunjukkan bahwa pertumbuhan kepiting bakau di tiga lokasi pada bulan ketiga diperoleh bobot akhir rata-rata dengan kisaran 131,05-199,50 g/ekor (163,17 ┬▒ 34,42); sintasan 22%-36,94% (30,41 ┬▒ 7,65); dan produksi 79,25-272,12 kg/ha (176,07 ┬▒ 96,43). Keuntungan tertinggi diperoleh pada lokasi Maros yaitu Rp5.454.750,00/ha/siklus dan terendah di lokasi Polman yaitu Rp317.150,00/ha/siklus. Nilai R/C rasio untuk semua lokasi menunjukkan lebih besar dari satu yang berarti bahwa usaha pembesaran kepiting bakau di tambak menggunakan krablet asal hatchery merupakan usaha yang layak. Ketersediaan pakan yang cukup, keberadaan shelter, pergantian air secara rutin dan kondisi kualitas air yang optimal merupakan faktor penting yang perlu diperhatikan untuk meningkatkan produksi pada ketiga lokasi di samping meningkatkan kepadatan sampai 1 ekor/m2.The grow-out cultures of hatchery-produced mudcrab seed in pond are rare and mostly part of research activities. The purpose of this study was to determine the performance of growth, survival rate, production, and develop a business analysis of mudcrab (S. tranquebarica) grow-out culture in different pond locations using hatchery-reared seed. The study was conducted in three pond areas in Maros, Pangkep, and Polewali Mandar (Polman). The ponds used in each location were traditional soil ponds with sufficient tidal system for water exchange. Crablets with a weight range of 0.05-0.1 g were reared in the ponds located in Pangkep, Polman and Maros with stocking densities of 0.24, 0.27 and 0.53 ind./m2, respectively. The feed used was trash fish or locally caught wild fish and given 5%-10% of the total crab biomass once every two or three days. The results showed that the average final weight of mudcrab in the three locations during three months rearing period was 131.05-199.50 g/ind. (163.17 ┬▒ 34.42) with survival rates of 22%-36.94% (30.41 ┬▒ 7.65), and crab production of 79.25-272.12 kg/ha (176.07 ┬▒ 96.43). The highest profit was obtained by grow-out culture in Maros location (IDR 5,454,750/ha/cycle) followed by Pangkep location (IDR 4,624,400/ha/cycle) and the lowest at Polman location (IDR 317,150/ha/cycle). The R/C ratio for all locations was greater than one which means that mudcrab culture in pond using seed from hatchery is economically feasibility

    During the COVID-19 pandemic, more community activities were at home with government policies to limit people's movements, especially in urban areas. During the period of restrictions on people's movements due to COVID-19, it was also followed by new habits, namely activities around the house, one of which was the increasing trend of Urban Farming to fill time. However, after the pandemic began to experience a downward trend, people no longer cared for their plants due to activities that had returned to normal. In this research, the design of Internet of Things technology was carried out to help urban communities to monitor and control plants so that people continue to carry out their daily activities without worrying about their plants running out of water. This study uses the NodeMCu V3 microcontroller as the data receiving center at the hardware layer and then a DHT 11 sensor is needed for temperature monitoring, a Soil Moisture sensor for monitoring soil moisture, a raindrop sensor for monitoring rain conditions as well as relays and a mini pump to control the water needs of plants. The results of this study are that the IoT device successfully displays temperature data, soil moisture data, rain status and automatic plant watering controls function properly if the value on the soil moisture sensor is below 25. The data communication path in this study uses the MQTT protocol using a webserver from Adafruit IO with an average packet loss of 0.20%. With the functioning of all the components on the created IoT device, the community can apply an IoT-based Smart Garden in urban farming so that plant maintenance can still be carried out

    The effects of an artificial commercial feed supplementation on larval rearing and crablet production of mud crab Scylla tranquebarica. In mass production of mud crab seeds, only rotifer and Artemia nauplii are usually fed to mud crab larvae rearing until the larvae develop to crablet stage. The supplementation of artificial commercial feed from zoea-3 stage is expected to supply an essential nutrient required for an optimum larval development. The research was aimed to determine the optimum dosage of commercial feed supplementation for a successful larval rearing to produce crablet in hatchery. Newly hatched larvae of mud crab were stocked at a density of 100 ind./L. The larvae were fed with rotifer and Artemia nauplii. Microbound artificial commercial feed sized <100 microns (protein 52%, fat 14,5%, fiber 3% and water content 10%) was supplemented to the larvae from zoea-3 to megalopa stage at different dosages namely: a). 0.5 mg/L/2 days; b). 0.75 mg/L/2 days; c). 1.0 mg/L/2 days; d). 1.25 mg/L/2 days. Larval population, larval development indices (LDI), megalopa occurrence index (MOI) and crablet production were observed and measured. Water quality (ammonium, nitrite, Total Organic Matter (TOM), and total Vibrio sp. count were also monitored. The LDI, MOI, and crablet production from each treatment were compared and tested using one way-ANOVA. The results showed that the survival rate of larvae at zoea-5 ranged between 29-33%. The LDI was not significantly different (P>0.05) among treatments. However, the MOI of treatment A and B at day 21 ph was significantly higher (P<0.05) compared with treatment C and D. In addition, the crablet production in treatment B, C and D were significantly higher (P<0.05) compared with treatment A. It was concluded that the supplementation of artificial commercial feed in larval rearing of S. tranquebarica could be applied at the dosage range of 0.75-1.25 mg/L/2-days from zoea-3 until crablet (C-7) stage

    One of the technologies to improve the productivity of shrimp farms are environmentally friendly shrimp farming multitrophic integrated system known as Integrated Multitrophic Aquaculture (IMTA). The aims of the study were to observe the water quality dynamic on the integrated multitrophic aquaculture and the effect on the production. This study was used four plots which each of pond had 4,000 m2 in sizing, located in experiment pond, at Research and Development Institute for Coastal Aquaculture, Maros. The main commodities used were tiger and vannamei shrimp. In the A pond was cultivated the tiger shrimp with density 12 ind./m2, in B pond was tiger shrimp with density 8 ind./m2, C pond was vannamei shrimp with density 50 ind./m2, and D pond was vannamei shrimp with density 25 ind./m2. Other commodities were red tilapia (Oreochromis niloticus). Each pond had stocking density 2,400 ind./plot which was divided into 5 hapas having a size of (6 m x 4 m x 1.2 m)/each, mangrove oysters (Crassostrea iredalei and Saccostrea cucullata) with density 7,500 ind./4,000 m2 and seaweed (Gracilaria verrucosa) of 500 kg/4,000 m2. The observation of dynamic water quality in the pond was conducted every day i.e. temperature, dissolved oxygen, salinity, and measured pH, while the total organic matter total (TOM), total ammonia nitrogen (TAN), nitrite, nitrate, phosphate were taken every two weeks. The measurements methods of water quality in laboratory was refered to APHA (2008); and Boyd (1990). During the study, absorption of N and P in seaweed were measured, the obtained plankton was identified and the ratio of carbon and nitrogen during the observation was also calculated. To determine the effect of dominant water quality on production was used the principal component analysis (PCA). The result showed that water quality during the study was suitable for shrimp and red tilapia culture. The dominant water qualities which effected the shrimp production in IMTA system were total ammonia nitrogen (TAN), oxygen, total organic matter (TOM), phosphate, and salinity. The survival rate of the tiger shrimp in intensive pond and semi intensive pond was 50.68% and 59.28% respectively, while the survival rate of the vannamei shrimp in intensive and semi intensive was 71.26% and 68.06% respectively. The highest shrimp production in the cultivation of IMTA reached was 1,488 kg/pond (3,720 kg/ha) in C pond. The lowest feed conversion ratio (FCR) was obtained in the D pond (0.89). The highest production of red tilapia in IMTA reached in C pond (426.65 kg/pond)

    This study was carried out to determine the physiological changes (survival, growth, molting cycle, sex differentiation, and gill condition) of mud crab, Scylla paramamosain crablet at different water temperatures of 24, 28 and 32 ┬░C, and ambient temperature of 27 to 30 ┬░C. Thermoregulatory behavior, represented by preferred temperature (29.83 ┬▒ SD 2.47 ┬░C), critical thermal minimum (17.33 ┬▒ SD 0.58 ┬░C), critical thermal maximum (40 ┬▒ SD 0.00 ┬░C), and thermal tolerance interval (22.67 ┬▒ SD 0.58 ┬░C), were checked for Crablet 1 stage only (with ambient temperature as acclimation temperature).Both low (24 ┬░C) and high (32 ┬░C) temperatures were associated with lower growth performance, and survival rate (p < 0.05), in comparison with both 28 ┬░C and ambient temperature treatments.Male ratio at low temperaturetreatment (24 ┬░C) was higher (80.09 ┬▒ SD 18.86%) than for other treatments (p < 0.05), observed as 44.81 ┬▒ D 10.50%, 41.94 ┬▒ SD 19.44%, and 76.30 ┬▒ SD 5.13% for 28 ┬░C, 32 ┬░C and ambient temperature treatments, respectively. However, there was no significant difference observed between 24 ┬░C, 28 ┬░C, and ambient temperature treatments. Anatomical alterations of gill lamellae of S. paramamosain crablet for both 32 ┬░C, and 24 ┬░C treatments, appeared thinner and paler than at both 28 ┬░C, and ambient temperature treatments. Based on this study, temperature of 28 to 30 ┬░C was recommended as the optimal temperature for the long-term nursery phase of S. paramamosain
