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.

Hasil menunjukkan bahwa perlakuan B menghasilkan performa terbaik dengan kelangsungan hidup 100%, penurunan bobot terendah (2,74%), dan CSI terendah (77,7). Kondisi suhu dan kelembapan kemasan juga paling stabil, masing-masing 25,8°C dan 99%. Temuan ini mengindikasikan bahwa kombinasi daun pisang kering dan sabut kelapa merupakan media pengisi paling efektif untuk mempertahankan kondisi fisiologis lobster selama transportasi sistem kering. Dry transport systems are an efficient alternative method for distributing freshwater lobsters, but they require a filling medium that can maintain the physiological stability of the organisms during transport. This research aims to evaluate the effectiveness of a combination of filling media consisting of dried banana leaves, coconut husks, and rice straw on survival, weight loss, cumulative stress index (CSI), temperature, and humidity during dry system transportation of freshwater lobsters of the species Cherax quadricarinatus. The study used a completely randomized design (CRD) with three treatments of filling media combinations: A (dried banana leaves + rice straw), B (dried banana leaves + coconut husks), and C (coconut husks + rice straw), each with three replicates. The results showed that treatment B produced the best performance with 100% survival, the lowest weight loss (2.74%), and the lowest CSI (77.7). The packaging conditions maintained the most stable temperature and humidity levels, measuring 25.8°C and 99%, respectively. These findings indicate that the combination of dried banana leaves and coconut husks is the most effective packing material for maintaining the physiological condition of lobsters during dry-system transportation
