Abstract

Large-scale mining activities are often not balanced with adequate post-mining management, causing post-mining land to become abandoned and environmental degradation. This study aims to evaluate the potential and opportunities for the implementation of post-mining land reclamation through the development of horticulture-based green infrastructure at PT Radik Jaya Indonesia, Kendal Regency. Identification of land conditions including soil and water characteristics, land cover, and the level of disaster vulnerability is carried out to support sustainable green infrastructure development planning. Research data was obtained through field surveys that included observations, measurements, and interviews, as well as laboratory analysis of soil quality. The collected data was analyzed using the scoring method to determine the level of land suitability in the development of green infrastructure. In addition, SWOT analysis is used to identify internal and external factors that affect the development of green infrastructure at the research site. The results of the study show that the development of horticulture-based green infrastructure has considerable potential as a component to support environmental sustainability as well as improve the community's economy. However, the development still faces a number of challenges, especially related to policy changes and the management of locations that are still actively used for mining activities. The resulting recommendations are expected to be the basis for planning and managing post-mining land reclamation in a sustainable manner, as well as contributing to environmental conservation and improving the economic conditions of the community in the research area.

Abstract

Kepel (Stelechocarpus burahol) is an endemic Javanese plant whose natural populations are declining, requiring conservation based on scientific evidence. This study aimed to characterize the morphological variation and analyze the phenotypic relationships of kepel populations across five ecological zones in Kebumen Regency: West, South, Central, East, and North. A total of 25 individuals were examined using a quantitative descriptive survey. Vegetative traits (leaf length, leaf width, stem diameter) and generative traits (flower diameter) were measured, while environmental parameters were recorded to support data interpretation. Numerical taxonomy analysis was conducted using the Unweighted Pair Group Method with Arithmetic Mean (UPGMA) based on standardized Euclidean distances. The results showed substantial morphological variation among zones, with stem diameters ranging from 27.7 to 30.5 cm and leaf lengths from 17.5 to 19.8 cm. Significant correlations were observed between soil pH, humidity, and temperature with key morphological traits (r = 0.70–0.90). The UPGMA dendrogram revealed three major clusters corresponding to distinct microhabitats. These findings indicate local adaptation of kepel populations in Kebumen and provide a scientific basis for both in situ and ex situ conservation of local germplasm.

Abstract

The purpose of this study was to analyze the income of farmers who grow langsat in Sulewatang village and evaluate the feasibility of their agricultural activities using profit ratio (R/C) analysis. The primary data used were obtained from direct interviews with farmers who grow langsat, as well as secondary data collected from related institutions. The analysis method includes calculating total income (TR = P × Q), total costs (TC = FC + VC), and profit ratio (R/C = TR ÷ TC). The results showed that the average income of farmers who grow langsat reached 2,241,190 Indonesian rupiah, with a total production cost of 360,769 Indonesian rupiah. Thus, the farmer's net income was 1,880,421 Indonesian rupiah. The profitability coefficient (R/C) value of 6.21 indicates that R/C > 1, which means that langsat cultivation in Sulewatang village is profitable and feasible to be further developed.

Abstract

disorder that activates compensatory mechanisms, including neurohormonal responses and circulatory adjustments, which initially preserve perfusion but later contribute to systemic and pulmonary congestion. This study examined the effect of acute and chronic CHF on VKORC1 gene overexpression and measured serum cardiac enzymes, namely troponin I (cTn I), creatine kinase MB (CK MB), lactate dehydrogenase (L LDH), and myoglobin (MYO MB), at each disease phase. The study included 40 CHF patients, consisting of 20 with acute CHF (ACHF) characterized by severe sudden cardiac symptoms and 20 with chronic CHF (CCHF) showing gradual progression, along with 20 healthy participants as a negative control group. Venous blood samples were collected for molecular analysis using quantitative PCR and for serological assessment of cardiac enzymes using quantitative ELISA. Statistical significance was determined using GraphPad Prism at p < 0.05. The results showed that, across all groups, the GG genotype frequency was significantly higher than GA and AA. However, allele frequency analysis of VKORC1 (-1639G>A) rs9923231 revealed significantly increased GA and AA frequencies in both ACHF and CCHF patients. Serologically, cTn I, CK MB, L LDH, and MYO MB levels were significantly elevated in both patient groups compared with controls. Between ACHF and CCHF, only CK MB was significantly higher in CCHF, while cTn I, L LDH, and MYO MB showed no significant difference. This appears to be the first Iraqi study linking VKORC1 with CHF phases, suggesting its potential as an indicator of both acute and chronic CHF, although further investigation is needed

Abstract

Food waste has emerged as a global issue of growing international concern, with developing countries striving to identify effective strategies to address the problem of food-related waste. In this study, food waste refers specifically to edible household food residues that are discarded despite being fit for consumption. This research aims to analyze the generation of food waste in Singkawang City and to examine the relationship between sociodemographic factors and the amount of food waste generated. The household sampling technique employed in this study was proportionate stratified random sampling, while the selection of individual family member respondents within each household was conducted using incidental sampling. The analytical methods applied include descriptive analysis, food waste quantification, and multiple linear regression analysis. The findings indicate that the highest level of food waste generation occurred in Singkawang Tengah District, producing the largest volume of waste (28,370 kg/year), while the lowest generation was recorded in Singkawang Utara District (7,140 kg/year). Furthermore, the results of the analysis examining the relationship between sociodemographic factors and food waste generation demonstrate that, simultaneously, sociodemographic variables (age, gender, income, education level, occupation, and number of household members) significantly influence the dependent variable (food waste generation). Partially, however, age, gender, education level, and occupation were found not to have a significant effect on food waste generation.

Abstract

Typhoid fever has increased in some populations, hence the current study, aimed to evaluate the prevalence of salmonella seropositivity and other relevant factors such as sex, age, and CRP positivity among febrile patients, especially among the patients estimated to be suffering with typhoid fever located at Al-Najaf province in Iraq. The study comprised 79 febrile patients who presented for intestinal complaints at Al-Hakeem General Hospital, AL Sajad Hospital, and AL Najaf Hospital’s serological departments within Al-Najaf province between October 2024 and January 2025. Those were between 1 and 75 years of age. This study employed rapid testing modalities for the qualitative detection of typhoid infection and assessment of serum CRP levels. Among the 79 febrile patients screened, 41 (51.9%) were female, 38 male (48.1%) was assessed. On typhoid seropositivity, 23 individuals (29.2%) tested positive, and 56 (70.8%) negative, but no differences between gender were found (P=0.36). Age distribution of febrile patients was further classified into 5 groups, 1-15 years, 16-30 years, 31-45 years, 46-60 years, 61-75 years. Notably, the greatest prevalence occurred at a range of 1 to 15 years of age (27.8%), then in the 16-30 year group (25.3%). Among those diagnosed as positive for Salmonella seropositivity, it was reported that those ages 61-75 had a higher positivity rate of 12.7%, indicating a statistically significant difference (P=0.001).

Abstract

Water is a primary necessity for human life, and its quality directly affects public health and community welfare. In Wayame Village, Ambon City, shallow wells are still used by the community as a source of water for daily needs, including drinking water. This study aimed to evaluate the chemical quality of shallow well water by comparing laboratory test results with the drinking water quality standards established by the Ministry of Health of the Republic of Indonesia. This study employed a descriptive quantitative method. A total of eight shallow well water samples were collected from community wells in Wayame Village using purposive sampling. The chemical parameters analyzed included pH, fluoride, total chromium, cadmium, nitrite, nitrate, iron, hardness, chloride, manganese, lead, and free chlorine. Laboratory analysis was conducted at the Provincial Health Laboratory of Maluku, and the results were compared with the Regulation of the Minister of Health of the Republic of Indonesia Number 492/Menkes/Per/IV/2010. The results showed that most chemical parameters were below the permissible limits for drinking water. Fluoride, total chromium, cadmium, nitrite, nitrate, iron, hardness, chloride, manganese, and lead were within the required standards. However, several samples showed pH values below the minimum standard, indicating slightly acidic water conditions. In addition, free chlorine levels in all samples were below the recommended range, indicating limited residual disinfection capacity.

Abstract

This study aims to analyze the hydro-oceanographic characteristics, identify the natural and anthropogenic factors causing coastal abrasion, assess the level of abrasion impact, and formulate an appropriate coastal abrasion management concept in the Batauga coastal area, South Buton Regency. A descriptive field-survey approach supported by hydro-oceanographic analysis and qualitative assessment was employed. Primary data were collected through bathymetric measurement, tidal observation, current measurement, field observation, documentation, and semi-structured interviews with relevant stakeholders. Bathymetric data were obtained using a GPS-integrated echosounder, tidal data were analyzed using the least squares method, and current velocity was calculated based on buoy displacement and validated with a digital current meter. The results show that the Batauga coast has a gentle bathymetric profile, allowing wave energy from the Flores Sea to reach the shoreline with limited attenuation. The mixed prevailing semidiurnal tidal pattern expands the active intertidal zone, while longshore currents contribute to sediment transport and sediment imbalance. In addition, illegal sand mining significantly accelerates abrasion by reducing sediment volume and altering seabed morphology. The level of abrasion impact is categorized as high, as indicated by shoreline retreat, seabed degradation, scouring around coastal structures, infrastructure vulnerability, and ecosystem damage. Therefore, a hybrid coastal protection system combining structural measures, non-structural strategies, vegetation rehabilitation, sediment stabilization, and strict control of sand mining activities is recommended for sustainable abrasion management in Batauga.

Abstract

Small Island worldwide are highly vulnerable to local food security and climate change. Therefore, appropriate spatial planning is needed to prevent the massive conversion of forest to non-forest areas, including sago, mangrove, and other natural forest on these small Island. This study used a method comprising a variety of activities, including field surveys, drone mapping, and interviews with sago owners and processors. The results showed that Ihamahu Village, on the small island of Saparua (Eastern Indonesia), had a sago forest area of ​​82.08 hectares with an average potential wet starch production of 450 kg per tree and a dry sago starch yield of 443 tons. This production enables local communities to process sago for household use and sell to the Saparua wholesale market. As sago has traditionally been a local food, the community continues to conserve forest in the region. In other words, sago potential has become a primary source of food security for local communities. With the ongoing conservation, the forest ecosystem is increasingly protected. The biomass content, especially of Mature Felling sago trees, was 30.33 tons per hectare, and this biomass would be even greater with the inclusion of Non-Mature Felling sago trees. This indicates that the sago forest ecosystem is capable of absorbing Greenhouse gas (GHG) emissions, thereby playing a significant role in mitigating climate change.
