Abstract

Batik industrial wastewater contains organic pollutants and suspended solids that may degrade water quality if discharged without treatment. Phytoremediation using aquatic plants offers an environmentally friendly alternative for wastewater management. This study aimed to evaluate the effects of plant type and detention time on the phytoremediation efficiency of batik wastewater using Salvinia molesta, Hydrilla verticillata, and their combination. The experiment was conducted using a Randomized Block Design with detention times of 0, 7, and 14 days. Water quality parameters, chlorophyll content, and plant biomass were analyzed using two-way Analysis of Variance (ANOVA) followed by Duncan’s Multiple Range Test (DMRT) at a significance level of p < 0.05. The results demonstrated that both plant type and detention time significantly improved wastewater quality (p < 0.05). The combined plant treatment at 14 days produced the most effective remediation, indicated by reduced BOD, TSS, and turbidity and improved pH conditions within quality standards. Longer detention time enhanced phytoremediation performance and supported plant growth under wastewater conditions. These findings highlight the ecological synergy between floating and submerged aquatic plants as a promising nature-based solution for sustainable batik wastewater treatment.

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

The Western tarsier (Cephalopachus bancanus) is a nocturnal primate distributed across Sundaland, including Bangka and Belitung Islands, where populations face increasing habitat disturbance and conservation threats. Geographic isolation may contribute to genetic differentiation between subspecies. Despite their conservation importance, genetic information for these insular populations remains limited. This study investigated the genetic variation and phylogenetic relationships of C. b. bancanus from Bangka Island and C. b. saltatorfrom Belitung Island using partial mitochondrial Cytochrome-B (Cyt-B) sequences. Ear tissue samples were collected from twelve individuals (six from each island), and DNA was amplified using GLUD-GL and CB2H primers. Amplified fragments ranged from 470–479 bp and showed high similarity (≥91%) with reference C. bancanus sequences in GenBank. Sequence alignment identified conserved and variable nucleotide sites, including parsimony-informative characters and singleton mutations. Haplotype diversity was high (Hd = 0.933), indicating substantial mitochondrial variation within the sampled populations. Phylogenetic reconstruction using the Neighbor-Joining method revealed partial clustering according to island origin, although several individuals shared closely related haplotypes across populations. The low level of sequence divergence may reflect historical connectivity between Bangka and Belitung during Pleistocene land bridge formation in Sundaland. These findings provide preliminary molecular evidence of evolutionary connectivity among island populations and emphasize the importance of integrating genetic information into future conservation and management strategies for Cephalopachus bancanus.

Abstract

Soil is an ecosystem containing various types of microbes with varying morphological and physiological properties. The number of each microbial group varies greatly, with some consisting of only a few individuals, while others number up to millions per gram of soil. The number of microbes influences the chemical and physical properties of the soil, as well as plant growth. By understanding the number and activity of microbes in a soil, it is possible to determine whether the soil is fertile or not, because a high microbial population indicates an adequate food/energy supply, appropriate temperature, sufficient water availability, and soil ecological conditions that support microbial growth. This study aimed to explore and isolate indigenous anaerobic microbes from the soil of Mount Ringgit, Situbondo, and identify their initial characteristics. This study employed a descriptive exploratory approach with laboratory experimental methods. Soil samples were collected using purposive sampling. The isolation process was carried out using a multilevel dilution technique followed by incubation under anaerobic conditions. The growing colonies were then purified and characterized macroscopically and microscopically. The results of the study showed that two distinct anaerobic bacterial isolates were obtained. Based on characterization, the isolates were identified as Clostridium sp. and Thiobacillus denitrificans. The presence of these two bacteria indicates that the soil of Mount Ringgit, Situbondo, has the potential for anaerobic microbial diversity, which plays a role in the decomposition of organic matter and the transformation of inorganic compounds.
