Abstract

Smoking remains prevalent in Indonesia and poses health risks to mothers and infants. Data from the Maternal and Perinatal Death Notification (MPDN) system indicate that maternal mortality increased to 4,129 cases in 2023 from 4,005 cases in the previous year. Although maternal mortality is multifactorial, this highlights the importance of reducing environmental risks such as secondhand smoke (SHS) exposure. SHS is common in household environments and may affect breastfeeding mothers and infants. Breast milk is the main source of infant nutrition and supports early immune protection. Lactoferrin, an iron-binding glycoprotein in breast milk, has antimicrobial, anti-inflammatory, and immunomodulatory functions. SHS-induced oxidative stress may damage the structural integrity of glycoproteins in breast milk, including lactoferrin, which can impair their immunological functions. This literature review aims to examine the potential role of lactoferrin as an immune biomarker in breast milk from mothers exposed to SHS. This study used a literature review approach by identifying, selecting, and synthesizing relevant scientific articles on SHS exposure, breast milk composition, lactoferrin, and infant immune protection based on predetermined inclusion criteria. The reviewed literature indicates that SHS exposure is associated with oxidative stress and inflammatory responses, which may interfere with lactation quality and alter immune-related glycoproteins in breast milk. Lactoferrin is considered a potential biomarker because it is related to antimicrobial activity, immune regulation, and infant protection against infection. This review concludes that reducing household SHS exposure is important to protect breastfeeding mothers and maintain breast milk immunological quality. Further empirical studies are recommended to examine the direct relationship between SHS exposure intensity and lactoferrin levels by considering lactation stage, maternal nutritional status, infant age, infection history, and breastfeeding patterns.

Abstract

Inflammation is a crucial mechanism by which the immune system combats disease. However, when it becomes uncontrolled, it can result in acute inflammatory disorders. Although non-steroidal anti-inflammatory drugs (NSAIDs) are widely used for treatment, their associated side effects have prompted the search for safer, natural alternatives. One of the enzymes central to the progression of acute inflammation is inducible nitric oxide synthase (iNOS), particularly its active site, plays a key role in the progression of acute inflammation. Lansium domesticum Corrêa, 1807 have been reported to contain secondary metabolites with anti-inflammatory potential, but their interaction with iNOS has not been systematically explored. This study is the first to comprehensively evaluate these secondary metabolites against iNOS using an in silico approach combing biological activity prediction, physicochemical and pharmacokinetic profiling, and molecular docking simulations. From 53 screened metabolites, nine compounds met drug-likeness and pharmacokinetic criteria and were further analyzed through molecular docking.  Ellagic Acid, (+)-Spathulenol, α-Cadinene, and τ-Muurolol showed substantial binding affinities at the iNOS active site, which suggests that they could be good anti-inflammatory agents. These results establish a basis for subsequent in vitro and in vivo validation aimed at creating safe, natural iNOS inhibitors as herbal-based for the alternative anti-inflammatory medicines.

Abstract

Lighting intensity strongly influences reproductive physiology and productivity in laying hens. This study examined the effects of different light intensities and lamp types on egg production traits in KUB chickens and modeled production dynamics using nonlinear regression. Four treatments were tested: control, 5-watt blue LED, 5-watt incandescent, and 5-watt white LED. Daily egg count, Hen Day Production (HDP), total egg weight, and average egg weight were analyzed using one-way ANOVA and Tukey’s HSD. Results showed that higher light intensities significantly increased egg count, HDP, and total egg weight (p < 0.05), while average egg weight remained unchanged. Logistic models best fit incandescent and white LED groups, whereas blue LED data aligned with an Exponential model. White LEDs offer an energy-efficient option for improving productivity.

Abstract

Keratin waste is highly recalcitrant due to its complex protein structure, requiring efficient biodegradation strategies. This study aimed to evaluate and optimize keratinase production of thermophilic Bacillus licheniformis AAL3 isolated from the Air Putih hot spring, Lebong, Bengkulu. Qualitative keratinolytic activity was determined using feather meal agar, while quantitative enzyme activity was measured spectrophotometrically based on tyrosine release. The isolate exhibited a higher keratinolytic index (5.0) compared to B. licheniformis SCL2 (1.5). Quantitative analysis showed that AAL3 produced higher cell density (8.9 × 10? CFU/mL) and keratinase activity (1.0074 U/mL). Optimization studies revealed that maximum keratinase production occurred at 60 °C and pH 9. Among the tested carbon sources, 1% glucose resulted in the highest cell growth and enzyme activity, whereas 0.4% peptone was the most effective nitrogen source. The results demonstrate a strong positive correlation between bacterial growth and keratinase production. These findings indicate that B. licheniformis AAL3 has significant potential as a thermophilic keratinase producer for biotechnological applications, particularly in keratin waste biodegradation.

Abstract

Pectin methylesterase (PME) plays a key role in polysaccharide digestion in the rice weevil Sitophilus oryzae, making it a potential molecular target for pest control. This study employed structure-based in silico analysis to evaluate selected metabolites of Lansium domesticum as PME inhibitors. Representative compounds were chosen according to predicted interference mechanisms and docked into the validated catalytic site. All complexes showed structural stability, while interaction patterns revealed six inhibition modes: competitive mimicry, catalytic disruption, orientation interference, channel blocking, polymer mimicry, and interfacial modulation, whereas polyphenols and glycosides produced the strongest interference. The findings indicate that L. domesticum metabolites can disrupt digestive enzymatic processes through multiple complementary pathways, supporting their potential development as biologically derived pest management agents.

Abstract. Hanum L, Usman SG, Oktariansyah Y. 2025. Genetic diversity and phylogenetic analysis of matoa (Pometia pinnata) from South Sumatra, Indonesia based on ITS rDNA. Biodiversitas 26: 5515-5524. Matoa (Pometia pinnata) is an ecologically and economically significant tropical fruit tree, however, its genetic variation in South Sumatra, Indonesia remains poorly characterized. This study aimed to examine the genetic diversity and phylogenetic relationships of four matoa variants, i.e., red, yellow, green, and forest types using ITS rDNA sequences. PCR amplification yielded sequences of 681 bp for cultivated and 478 bp for forest matoa, revealing two InDel haplotypes, 141 InDel sites, and three InDel events with moderate haplotype diversity (Hd = 0.50) and low InDel diversity per site (?i = 0.001). These findings indicate limited but informative structural variation linked to insertion-deletion mutation events, supporting the ITS region’s dual role as both a conserved barcode and a marker for intraspecific differentiation. Phylogenetic and AMOVA analyses showed clear separation between cultivated and forest variants, with almost all genetic variation (99.9997%) partitioned among populations (Fst = 0.999997), suggesting restricted gene flow and possible ecological divergence. Despite high sequence similarity of 99.85% to 100% confirming conspecificity, forest matoa formed a distinct clade and grouped separately, highlighting its potential as a unique genetic reservoir. These results provide foundational molecular insights for conservation, breeding, and germplasm authentication strategies for matoa in Indonesia.

Abstract. Hanum L, Wahyuni T, Oktariansyah Y. 2026. Genetic diversity of pigmented rice landraces (Oryza sativa) from South Sumatra, Indonesia revealed by SSR markers. Biodiversitas 27 (1): d270130. https://doi.org/10.13057/biodiv/d270130. Pigmented rice landraces constitute an important component of Indonesia’s rice genetic resources, yet information on their molecular diversity in South Sumatra remains limited. This study tested the hypothesis that pigmented rice landraces from South Sumatra exhibit SSR-detectable genetic variation among accessions, whereas genome-wide differentiation between pigmentation groups (red and black rice) is weak or non-significant. This study assessed the genetic diversity and relatedness of ten local pigmented rice (Oryza sativa) landraces, comprising seven red and three black rice accessions, using 11 Simple Sequence Repeat (SSR) markers. All markers produced clear and reproducible amplification profiles, generating fragments ranging from 127 to 480 bp, with six to twelve alleles per locus. Marker informativeness was consistently high, with PIC values of 0.790-0.917 (mean = 0.878), indicating strong discriminatory power for accession differentiation. SSR profiles were predominantly homozygous, reflecting the autogamous reproductive system of rice, although limited heterozygosity was detected at a few loci in specific accessions. Multilocus comparison revealed moderate divergence among landraces, supported by Jaccard similarity coefficients ranging from 0.769 to 1.000. UPGMA clustering resolved a structured pattern consisting of a closely related core group of accessions, an intermediate subgroup represented by Linggau and Tanjung Agung, and a more divergent subgroup comprising Sumber Jaya and Teluk Tenggirik. However, AMOVA indicated that molecular variation was predominantly distributed within populations (100%) rather than among populations (0%), with a non-significant differentiation between red and black rice groups (Fst = -0.038; p = 0.769). These findings provide baseline molecular evidence supporting conservation prioritization and highlight genetically distinct landraces as potential donors for future pigmented rice breeding programs. This study represents one of the few SSR-based molecular assessments focusing specifically on pigmented rice landraces from South Sumatra, Indonesia.
