Abstract

Tingkat kelangsungan hidup dan pertumbuhan benih rajungan saat pendederan masih rendah. Penggunaan pakan alami untuk meningkatkan kelangsungan hidup dan pertumbuhan belum banyak dilakukan. Pemberian pakan buatan dan pakan segar sering dapat menyebabkan terjadinya penurunan kualitas air. Hasil penelitian tentang pemanfaatan pakan alami pada pendederan masih sangat kurang dilakukan. Penelitian ini bertujuan untuk mengetahui rasio pemberian Phronima Sp dan Artemia salina pada pendederan crablet rajungan yang dapat meningkatkan kelangsungan hidup dan pertumbuhan. Penelitian ini dilaksanakan di unit pembenihan rajungan Balai Perikanan Budidaya Air Payau Takalar pada bulan Maret-Mei 2023. Rancangan penelitian menggunakan Rancangan Acak Lengkap (RAL), diuji dengan menggunakan wadah 30 liter sebanyak 15 buah di mana setiap wadah yang diisi dengan 20 liter air laut steril bersalinitas 31- 32 ppt dan ditebar crablet rajungan (C5) sebanyak 20 ekor setiap wadah. Ada 5 perlakukan dan 3 ulangan yaitu A: Phronima sp 100%, B: Artemia salina 100%, C: Phronima sp 50%+Artemia salina 50%, D: Phronima sp 25%+Artemia salina 75% dan E: Phronima 75%+Artemia salina 25%. Hasil Penelitian menunjukkan bahwa Phronima sp 25%+Artemia 75% merupakan rasio yang terbaik. The survival rate and growth of crab rajungan in nursery was still low. The use of natural feed to improve survival and growth has not been widely carried out, artificial feeding and fresh feeding can often lead to a deterioration in water quality. The resullt of research on the use of natural feed in nursery is still lackin. This study aimed to determine the ratio of Phronima Sp and Artemia salina in crablet nursery which can increase survival and growth. This research was conducted at the mackerel hatchery unit of the Takalar Brackish Water Aquaculture Fishery Center in March-May 2023. The research design used a Completely Randomized Design (CRD), tested using 15 unit 30-liter containers, each container filled with 20 liters of sterile seawater with a salinity of 31-32 ppt and 20 crablets (C5) were stocked in each container. There were 5 treatments and 3 repetitions, namely A: Phronima Sp. 100%, B: Artemia salina100%, C: Phronima sp 50% + Artemia salina 50%, D: Phronima Sp. 25% + Artemia salina 75% and E: Phronima 75% + Artemia salina 25%. The research result showed that the ratio of Phronima Sp 25%+Artemia salina 75% is the best ratio.

Frekuensi pemberikan pakan dilakukan sebanyak dua kali sehari dengan dosis 5% dari bobot tubuh hewan uji. Parameter uji yang diamati yaitu suhu, pH, DO, amonia (NH3), nitrit (NO2), dan hidrogen sulfida (H2S). Hasil penelitian menyimpulkan bahwa konsentrasi pakan tepung keong mas dengan berbagai dosis berbeda memberikan pengaruh (p<0.05) terhadap kadar amonia (NH3) diawal dan diakhir penelitian. Kadar amonia (NH3) pada perlakuan D (0%) diakhir penelitian telah melebihi baku mutu air untuk kegiatan perikanan kelas III (0,02 mg/L). Sedangkan konsentrasi pakan tepung keong mas dengan berbagai dosis berbeda tidak memberikan pengaruh (p<0.05) terhadap kadar nitrit (NO2) dan kadar H2S diawal dan diakhir penelitian. Kadar nitrit pada semua perlakuan telah melebihi baku mutu air untuk kegiatan perikanan kelas III (0,06 mg/L) dan kadar H2S pada semua perlakuan masih berada dibawah batas ambang baku mutu air (0,05 mg/L). The purpose of this study was to analyze the water quality parameters of the rearing medium for Tilapia (Oreochromis niloticus) seeds which were fed feed made from golden snail flour (Pomacea canaliculata) including temperature, pH, DO, NH3, NO2, and H2S. This research took place at the Laboratory of the Aquaculture Study Program, Faculty of Agriculture, Bosowa University, which was carried out for 5 weeks, from April to June 2023. This research was an experimental study using four treatments and three replications. The treatment given by golden snail was with treatment dose A (70%), treatment B (65%), treatment C (60%), and treatment D (0%). The frequency of feeding was carried out twice a day at a dose of 5% of the body weight of the test animals. The test parameters observed were temperature, pH, DO, ammonia (NH3), nitrite (NO2), and hydrogen sulfide (H2S). The results of the study concluded that the concentration of golden snail flour feed at various different doses had an effect (p<0.05) on ammonia (NH3) levels at the beginning and at the end of the study. The level of ammonia (NH3) in treatment D (0%) at the end of the study exceeded the water quality standard for class III fishing activities (0.02 mg/L). Meanwhile, the concentration of golden snail flour feed with various different doses had no effect (p<0.05) on nitrite (NO2) and H2S levels at the beginning and end of the study. Nitrite levels in all treatments exceeded the water quality standard for class III fishing activities (0.06 mg/L) and H2S levels in all treatments were still below the water quality standard threshold (0.05 mg/L).

Abstract

Stunting is a problem of chronic malnutrition caused by insufficient nutritional intake over a long period of time due to the provision of food that does not meet nutritional needs. This research uses descriptive qualitative research methods. The qualitative approach was chosen because the data collected was natural. The aim of this research is to find out how to implement the Pandeglang Regency Regent's Regulation Policy Number 28 of 2019 concerning the Acceleration of Stunting Reduction (Case Study of Banjarsari Village, Kaduhejo District). The problems found in this research are the high stunting rate in Paandeglang Regency amounting to 29.4% in 2022, the discrepancy in the recapitulation data of stunting cases between those recorded at the Health Service and those at the health centers accessed via e-PPGM, lack of community participation and community support in participating in the Stunting reduction program, lack of supervision and monitoring from the Health Service and Community Health Centers, lack of understanding and public awareness about the importance of balanced nutrition for children's growth and development. The theory used is the Implementation theory from Van Metter and Horn. From this research it is known that in implementing the Pandeglang Regent Regulation Number 28 of 2019 concerning the Acceleration of Stunting Reduction (Case Study of Banjarsari Village, Kaduhejo District) it can be said that the results are quite good but there are still deficiencies and obstacles in its implementation that prevent stunting reduction programs from running optimally. This is caused by several obstacles, namely the social conditions of the community, the habits of the community, the availability of a budget that is not yet fully adequate, the understanding of some implementers is still not optimal, then regarding the targets, everything is already in this Regent's Regulation, but in its implementation there are still data inconsistencies. data in the field.

Abstract

Kualitas warna ikan koi sangat dipengaruhi oleh kandungan nutrisi pakan, khususnya karotenoid sebagai prekursor pigmen. Maggot Black Soldier Fly (Hermetia illucens) berpotensi menjadi sumber karotenoid alami karena mampu mengakumulasi pigmen dari substrat pakannya. Sel kromatofor pada ikan menunjukkan respons berbeda terhadap variasi kandungan pigmen dan nutrisi, sehingga jenis media kultur maggot dapat memengaruhi intensitas warna ikan. Penelitian ini menggunakan Rancangan Acak Lengkap dengan empat perlakuan dan tiga ulangan: (A) maggot yang diberi pakan labu kuning, (B) buah naga, (C) pepaya, dan (D) kontrol. Hasil penelitian menunjukkan bahwa maggot yang dikultur menggunakan labu kuning memiliki kandungan karotenoid tertinggi (0,3269 mg/L), diikuti perlakuan pepaya dan buah naga. Perlakuan A juga memberikan peningkatan warna paling signifikan, dengan skor 25 pada skala TCF dan jumlah sel kromatofor tertinggi, yaitu 1.255 sel. Peningkatan jumlah sel kromatofor menyebabkan distribusi pigmen lebih merata sehingga menghasilkan warna koi yang lebih cerah. Seluruh perlakuan menunjukkan tingkat kelangsungan hidup 100% selama 30 hari pemeliharaan. Parameter kualitas air selama penelitian berada dalam kisaran optimal bagi kehidupan ikan koi. The nutritional content of koi fish's feed, particularly the carotenoids that serve as pigment precursors, greatly influences their color quality. Black soldier fly maggots (Hermetia illucens) have the potential to be a source of natural carotenoids because they are able to accumulate pigments from their feed substrate. Chromatophore cells in fish show different responses to variations in pigment and nutrient content, so the type of maggot culture medium can affect the intensity of fish color. This study used a completely randomized design with four treatments and three replicates: (A) maggots fed yellow pumpkin, (B) dragon fruit, (C) papaya, and (D) control. The results indicated that maggots cultured using pumpkin had the highest carotenoid content (0.3269 mg/L), followed by the papaya and dragon fruit treatments. Treatment A also provided the most significant color enhancement, with a score of 25 on the TCF scale and the highest number of chromatophore cells, namely 1,255 cells. The increase in the number of chromophore cells caused a more even distribution of pigments, resulting in brighter koi colors. All treatments showed a 100% survival rate during the 30-day maintenance period. Water quality parameters during the research were within the optimal range for koi fish life.

Abstract

This study aims to determine suitable biomarkers as monitoring tools for detecting heavy metal pollution in the Maros River. The analysis results showed that the livers of Corbicula javanica from the Maros River contained metallothionein Pb and metallothionein Cd. The average accumulation values of Pb and Cd that induced the appearance of metallothionein Pb were 0.001628 ppm and 0.004929 ppm, respectively. This study demonstrates that Corbicula javanica clams exhibit a significant biological response to exposure to heavy metals Pb and Cd in the Maros River, as evidenced by high bioaccumulation levels, the presence of the molecular biomarker metallothionein, and disturbances in physiological parameters such as the Gonad Somatic Index (GSI). Cd exhibited higher and faster accumulation patterns and Bioaccumulation Factor (BCF) values compared to Pb, indicating stronger toxicity potential and biological retention. The expression of Cd and Pb metallothionein in liver tissue, which appeared in the first and fifth weeks of exposure, demonstrated the high sensitivity of these biomarkers as early detection tools for heavy metal contamination. Conversely, although the GSI values of river freshwater clam were significantly lower than those of the control group, this parameter proved less sensitive to specific metal types, making it unsuitable as a sole indicator for early detection of contamination. The positive correlation between metal concentrations in tissues and shifts in physiological distribution, as determined by Principal Component Analysis (PCA), further supports the finding that freshwater clams experience stress accumulation over time. Based on the results obtained, Pb metallothionein and Cd metallothionein are biological markers (biomarkers) that can be used as tools for early detection of water pollution.
