Abstract

Excessive groundwater extraction can result in the intrusion of seawater inland, contaminating the aquifer conditions in the Jakarta Groundwater Basin or commonly known as seawater intrusion, impacting the use of water for daily domestic and industrial needs. Therefore, an analysis is conducted to generate the seawater intrusion spread zones using a groundwater classification method on 54 samples from the confined aquifers of the Jakarta Groundwater Basin. Based on the analysis results of classified groundwater facies using the Piper diagram, facies such as CaHCO3, NaHCO3, MgHCO3, NaCl, and NaSO4 are identified, with CaHCO3 dominating from west to east and NaCl in the northern region of Jakarta, resulting in a groundwater salinity classification of 2, ranging from fresh to brackish water. A Na/Cl ratio <1 may be attributed to seawater mixing into the aquifer, possibly due to low rates of rainwater flushing through percolation. Conversely, a high Na/Cl ratio indicates interactions between groundwater and rocks through hydrolysis and acid-base reactions. Besides the Na/Cl ratio, a CL/HCO3 ratio <0.5 indicates no influence, 0.5 to 6.6 indicates slight to moderate influence, and >6.6 indicates high influence. Moreover, seawater intrusion classifications are divided into four categories: freshwater, slight seawater intrusion, moderate seawater intrusion, and relatively high seawater intrusion. This research is also expected to provide further evaluation, especially on an annual basis, particularly in the North Jakarta, East Jakarta, and Bekasi Regency areas.

Abstract

Kampung Unggul Balitnak Chicken (KUB) is a highly favored Indonesian native chicken breed among breeders because of its rapid development rate and ability to thrive in many situations. This study aimed to investigate KUB chickens' growth performance and morphometric parameters at 60 days of age, a crucial phase for determining their suitability as commercial broilers. Using an intensive rearing system, 100 KUB chickens were reared for 60 days in group cages. Body weight measurements were recorded weekly, and morphometric traits were measured after the study period. The study's findings indicated that the mean body weight of KUB chickens at 60 days of age was 710.53±16.76 grams, suggesting a favorable growth rate. In addition, the morphometric analysis revealed favorable physical characteristics, including an average chest length of 100.55±3.70 mm, chest width of 47.47±3.12 mm, wing length of 165.93±4.34 mm, back length of 164.9±4.26 mm, back height of 205.51±3.99 mm, shank length of 63.23±3.69 mm, and shank circumference of 35.76±1.48 mm. The results indicate that KUB chickens exhibit desirable body weight and morphometric traits at 60 days old, proving their suitability in commercial broiler farming. To summarize, this study offers significant information regarding the growth performance and physical characteristics of KUB chickens during a critical phase of their development. The findings highlight the breed's capacity to serve as a practical choice for commercial broiler production, enhancing the variety and long-term viability of the poultry sector in Indonesia.

Abstract

The immune system of Kampung chickens is vital for maintaining health and productivity, especially in combating bacterial infections. Among the genetic components involved, the inducible nitric oxide synthase (iNOS) gene is crucial for producing nitric oxide (NO), a molecule with strong antimicrobial properties. This study investigated the association between iNOS (AluI│g.15056T>C) gene polymorphism and immune traits in Kampung chickens to enhance disease resistance. Blood samples from 100 Kampung chickens were genotyped using PCR-RFLP, and immune parameters such as leukocyte count, macrophage activity, and bacterial resistance were evaluated. Statistical analysis revealed significant differences among TT, TC, and CC genotypes. The CC genotype exhibited superior performance, including the highest macrophage activity (91.74±1.92%), activated macrophage capacity (2279.49), and bacterial death rate (60.81±3.54%). These findings suggest that the CC genotype enhances NO production, strengthening the immune response to bacterial pathogens like Staphylococcus aureus and Salmonella Pullorum. Additionally, the polymorphism contributes to improved genetic diversity and immune efficiency in Kampung chickens. The study highlights the potential of incorporating the iNOS CC genotype in selective breeding programs to produce chickens with enhanced resilience. Future research should focus on interacting environmental factors with iNOS expression to optimize its application in chicken production.

Abstract

Indonesian local chickens are essential genetic resources with significant potential for advancing the national poultry industry due to their high genetic diversity, reflecting adaptation to tropical environments and traditional farming systems. This study analyzed the genetic diversity of Kampung, Sentul, KUB, SenSi, and Broiler chickens based on the MSTN g.4842T>G locus. Blood samples from 150 chickens underwent PCR-RFLP analysis using the BsrI restriction enzyme targeting exon 2 of the MSTN gene. Parameters such as observed heterozygosity (Ho), expected heterozygosity (He), polymorphism information content (PIC), and Hardy-Weinberg equilibrium were assessed. Genetic distances were calculated using PHYLIP, and a dendrogram was constructed with UPGMA. The study identified two alleles (G and T) and three genotypes (GG, GT, TT), with the T allele being dominant, particularly in Broiler chickens (78.3%). Ho was lower than He in all populations, indicating a heterozygosity deficit. PIC values ranged from 0.282 (Broiler) to 0.367 (SenSi), classifying the MSTN locus as moderately polymorphic. Kampung and KUB chickens showed the closest genetic relationship, while Broiler chickens were the most distinct. These findings underscore the potential of local chickens in breeding programs for adaptability and productivity. Further research with additional markers is recommended to enhance sustainable poultry farming.
