Published: November 2022

Sustainable waste management is an important global environmental agenda in the twenty- first century. The quantity of global waste increases as the population and the level of resource consumption rise over time. The increased generation of waste is also producing bigger environmental deprivation: in particular pollution of land, water, and air due to uncontrol and unsustainable waste disposal and management options. According to the Intergovernmental Panel on Climate Change, the waste sector contributes less than 5% of global GHG emissions, which is very low compared to the energy and industrial sectors (more than 65%).

Several tools are available for evaluating the environmental level and/or performance of waste management in an area using several benchmarking indicators, such as life cycle assessment, multi-criteria decision analysis, compositional analysis etc. Often these tools are the simplifications of the actual facts as the waste management systems are complex and difficult to generalise from case studies

This research uses several benchmarking indicators such as compositional analysis of household waste, level of recycling index, participation in home composting, awareness activities, prevention activities in order to assess the level of the circular economy strategy in a Municipality (located in Cyprus)

The results indicate that the more than 75% of the citizens are participated in the recycling door to door program but the recyclable waste that are delivered are not clear as there are several other wastes. For example, the concentration of other waste in PMD is more than 20% indicated that a door to door training program is needed. Also, the concentration of PMD and Papers in the household waste count more than 18% indicated that the waste sorting at source needs further attention. Home composting seems to be a promising method to treat leftovers and other yard wastes and minimized the volume of organic waste that are dumped in landfills. The results of the compositional analysis highlighted the need to develop actions to divert specific waste streams such as recyclable, green and food waste, as well as the development of awareness activities.

The evaluation of the existing management plan indicated that among the main weaknesses is the level of educational program that are totally missed and the awareness activities while at the same time the prevention activities (beside home composting) needs further attention.

Published: November 2022

Contamination of water resources with Arsenic poses serious health concerns because of its toxic and carcinogenic nature. Detection of Arsenic at concentrations higher than 10 parts per billion (ppb) in some Philippine water resources confirmed the need for further studies on the contamination and for the investigation of potential treatment technologies.
This study examined the removal of Arsenic from synthetic contaminated water, with initial concentrations of 100 ppb and 300 ppb, using electrocoagulation process. The electrocoagulation batch reactor utilised combined iron and aluminum electrodes, in parallel configuration.
Employing a Box-Behnken experiment design for response surface modeling (RSM), three factors were investigated with each factor varied at three levels – pH of the wastewater solution current density and reaction time.
Results showed that at optimum parameters of pH 7, 25 A/m2 current density and 40 minutes reaction time, the electro coagulation reactor was able to reduce the 100 ppb Arsenic in water by 99.20%. At optimum parameters of pH 7, 20 A/m2 current density, and 40 minutes reaction time, the 300 ppb Arsenic in water was reduced by 98.23%.

Published: November 2022

The standard method for the estimation of reference evapotranspiration (ETo) is FAO-Penman-Monteith (FAO56-PM). However, it requires various climatic parameters which are often hard to achieve due to various reason. In order to bridge this gap an alternative equation has to be find out. The main aim of this research work was to assess the performance of the various mass transfer-based method with respect to standard FAO56-PM. Daily meteorological data from 1980 to 2018 has been used to compute reference evapotranspiration. Daily ETo values were computed. Among the computed values 70% of them were used to calibrate the mass transfer equations under study and remaining 30 % data were used to validate the calibrated equation against the standard method. The calibrated models were analysed and compared using statistical tools and ranked using Global Performance Indicator where a higher value represented a model’s better performance. The models were then arranged using GPI and it was found that Albrecht model resulted in best estimation capability. The results of this study could be used by the water management system, crop cultivators, crop advisors, researchers and students from universities and research centres. Moreover, it is beneficial for the decision maker in the vast field of agriculture, hydrology and environment.

Published: November 2022

This work aims at investigating the efficiency of applying calcium polysulfide (CPS) as a reducing agent for the decontamination of a heavily Cr(VI)-contaminated aquifer. Series of batch experiments were carried out in order to evaluate the reductive behavior of CPS towards the aqueous and solid phase. CPS was added in several stoichiometric excesses (2.0X, 2.6X, 4.6X and 6.5X) with respect to the Cr(VI) concentration measured in the contaminated groundwater. The effect of time on Cr(VI) reduction by CPS was tested performing short term batch experiments. In addition, the effect of CPS on other groundwater constituents, e.g. nitrates, and potential mobilization of soil elements, sensitive to redox changes (Mn, As, Co, etc.), were also evaluated. The experimental results showed that CPS can be effectively used for the remediation of the Cr(VI) contaminated aquifer without affecting significantly the soil properties.

Authors: Özçakır Gamze , Karaduman Ali
Published: November 2022

Co-Pyrolysis of Low Density Polyethylene (LDPE) and Polystyrene (PS) was carried out in a semi-batch glass reactor system. Effects of temperature and feedstock ratio on pyrolytic product yields (gaseous, liquid and solid residue) and chemical composition of the liquid were investigated. All experiments were performed with 15 g feedstock in 25 mL/min nitrogen atmosphere and 60 min duration at specified temperature. Temperature was changed from 470 to 620 °C with 50 °C break by utilizing PID controller which was setted 10 °C/min heating rate. PS in the feedstock was varied as 0, 33, 67, 100 wt. %. The liquid products were characterized by GC-MS. When PS and LDPE were mixed equally by weight at 570 °C, liquid product yield was found 85 wt. %. More PS adding in the feedstock did nearly not affect this value. It was detected that hydrocarbons which were aromatic, cyclic and aliphatic formed the peak areas’s majority of the co-pyrolytic liquid. Specifically styrene was found dominant component in that liquid. Besides that, it was observed that with increasing temperature, peak areas’ percentage of alkanes decreased while temperature rising didn’t affect olefines’ peak areas.

Abstract. Principal Component Analysis (PCA) and Hierarchical Cluster Analysis (HCA) were applied in the groundwater hydrochemical parameters dataset of the Tirnavos alluvial sub basin-central Greece. PCA results suggest occurrence of four principal components both for dry and wet periods. Results of HCA application enabled to divide groundwater samples into two major groups with a large disparity in the number of samples for both periods. Implementation of these methods and spatial distribution of their corresponding results assist revealing key hydrodynamic evolution patterns and hydrochemical dependencies to anthropogenic and geogenic factors.

Published: November 2022

Grey water and rain water are two options as alternative sources to alleviate water stress/scarcity across the world. This paper aims to investigate possible use of reclaimed grey water and harvested rain water from on-site premises as sources of flush water and irrigational water in and around households in the popular settlement district Atakoy of the water-stressed Turkish megacity Istanbul. Calculations using demographic and meteorological data along with an analysis of current municipal plans reveal that the rain water potential is 544 434 and grey water potential 2 070 662 (total)/880 032 (light grey water) m3/year in Atakoy. This indicates that 78% of 3 347 669 m3/year demand for flushes and irrigation of the entire green areas of privately-owned housing complexes may be covered by rain water and grey water in the area. While the entire flush water demand may be covered by light grey water only, 79% of flush water may be supplied if rain water is used. 98% of irrigational demand may be provided using both light grey water and rain water. The results show that considerable water savings may be achieved through the use of grey water/rain water which will aid sustainability.
Reduction of Halogenated Organic Compounds in Water: Comparison of Available Reduction Systems based on Cu, Pd and ZVI
Authors: Shee A. , Kopinke F.-D. , Mackenzie K.
Published: November 2022

Catalysts on the basis of copper (Cu) and the reducing agent borohydride (BH4-) have been successfully used for reduction of chlorinated aliphatics with low substitution degree which are usually resistant to zero-valent iron (ZVI) and hydrodehalogenation catalysts, such as Pd. Reactivity screening towards a broad spectrum of halogenated organic compounds (HOCs) helped to reveal the possible application areas of the Cu/BH4- system in water treatment compared to Pd and ZVI. The HOC reactivity was found to depend on: i) the nature of the C-X bond to be cleaved, ii) the functional groups adjacent to the C-X bond and linked to it, iii) the bond dissociation energy (BDE). The use of the deactivation-stable Cu/BH4- can be recommended as alternative reduction method to ZVI and Pd catalysts for on-site treatment of aliphatic HOCs.

Waste to Energy Initiatives at the Local Level
Authors: LIM DAVID, JR. , BALLESTEROS FLORENCIO, JR. , DE SALES LOUANNE GRACE
Published: November 2022

The problem on solid waste has been and still remains as a major problem in the Philippines especially in developing countries where proper facilities for collection and disposal are not always available. In Metro Manila alone, daily waste generation stands at 8,600 tons coming from a population 12.8M. The infrastructure has already reached its maximum capacity resulting to major upsets in environmental quality. The sheer volume of solid waste generated daily poses a big challenge for disposal options since reuse and recycling methods are the only the socially acceptable options. Incineration though not strictly banned by law has never been initiated apparently due to lack of a scientific understanding of the process and its appreciation as a safe and viable process of handling solid waste. Meanwhile, depletion of available capacities of sanitary landfills proceeds at an accelerated phase because of the sheer volume of solid waste to be disposed compounded by the reluctance to implement waste to energy options of waste disposal. In a bid to address the issue, the Philippine Congress legislated a law to require all local government units (LGU) in the country to develop a comprehensive solid waste management plan. Notwithstanding these efforts, the problem remains far from over. The volume of waste ending up in the landfill continues to be the dominant concern. Should the the problem persist, hazards, ground and surface water contamination, flooding, air pollution and spread of diseases will continue to present major problems. Hence, initiatives to reduce the volume of waste that is both environmental sound and sustainable is called for. A waste to energy (WTE) path can easily fulfill these requirements.
This paper provides information on WTE developments in the Philippines seeking to encourage LGUs to consider WTE as one of the waste diversion methods in promoting environmentally sound management (ESM) of Municipal Solid Waste (MSW). Complementing this objective is for the country’s Department of Energy (DOE) to change its policy on Renewable Energy (RE) to include solid waste as part of the biomass category and incorporating market driven incentives to encourage investors and waste practitioners to choose WTE as a sustainable approach in managing MSW while considering the triple bottom line (TBL) approach (Profit, People and Planet) to ensure sustainability.

Continuous Atmospheric Boundary Layer (ABL) temperature profile measurements are of particular interest in a variety of applications and studies, including air pollution and pollutants dispersion, agricultural meteorology, aeronautical meteorology, mesoscale meteorology, weather forecasting, climate studies, energy applications. Several methods have developed and are applied for these measurements, being both direct (in situ) by using sensors located on tower structures, balloon-borne instrumentation, until aircraft techniques and indirect or remote sensing techniques. The latest mainly involve transmitted acoustic, radio, or light energy, and the detection of the scattered energy due to atmospheric targets. Passive techniques involve the measurement of radiation naturally emitted from the atmosphere, for example, as in microwave and infrared radiometry. In this work, the technique of passive microwave radiometry for the measurement of the temperature profile in ABL is described and some measurements are presented and analyzed. These measurements carried out in the industrial area of Western Macedonia, a large and broad mountain basin in NW Greece, by using the MTP-5 system. MTP-5 is a remote sensing instrument that measures microwave radiation emitted from the lower 1000 m of the atmosphere, within the Planetary Boundary Layer. The measurements of the temperature profile during two typical cases (hot and cold season) are analyzed and the ABL development are being investigated. Finally, some concluding remarks are provided.

Published: November 2022

Soil resource is essential for livelihood of human being. Soil erosion is one of the most serious natural problem affected by land degradation, agricultural and other human induced activities, such as climate change, particularly the changed precipitation trend. The aim of the study is applying the Revised Universal Soil Loss Equation (RUSLE) with the help of remote sensing and geographic information system techniques to calculate soil loss and to map soil erosion of the Marmara Region of Turkey in the changing climate conditions between 1989 and 2017, and also to make future projection of soil erosion for the years between 2020 and 2049. This model is composed of variety of factors associated with climate, vegetation, soil and topography.
The results of the study showed that according to the two scenarios of the Regional Climate Model RCP 4.5 (optimistic), and RCP 8.5 (pessimistic), the future soil loss of the Marmara Region in the changing rainfall events is higher than the results of the historical data. The soil loss results for the time interval 2020-2049 of the scenario RCP8.5 is 61% higher than the results of the scenario RCP4.5. Also, the soil loss results of the historical data of the Regional Climate Model showed that the soil loss range from 0 to 24,298 Mg. ha-1. year—1 during the time interval 1989 – 2017 in the Marmara Region, and also the average soil loss is 12,2 Mg. ha-1. year—1 .

Challenging the belief that organic waste and plastic should be diverted from landfill on climate change grounds:
Authors: Hutton B , Norrish M , Horan E
Published: November 2022

Abstract Landfill is generally believed to have higher greenhouse gas emissions than composting or waste-to-energy. The EU Landfill Directive requires nations to progressively divert biodegradable waste away from landfill. Waste disposal in landfill is at the bottom of its Waste Hierarchy. Many nations also ban landfilling of plastic. These policies may inadvertently increase global warming by increasing incineration. In Europe, Waste-to-Energy (WTE) incineration emits 72,000,000 tonnes of fossil CO2 a year, increasing yearly. Landfill methane is now generally captured. Nations that directly measure landfill gas emissions (the UK, Ireland and USA) now report about 65- 75% landfill gas recovery; the average for California is 79%. It is now almost always used to generate electricity. When burnt it does not emit fossil CO2. Landfill is a carbon sink, sequestering about half of the organic carbon deposited in it, long-term, like peat. This reduces the global flux of CO2.

Published: November 2022

The co-pyrolysis of lignocellulosic wastes such as Corn stover with plastic has been found to improve the both the yield and quality of pyrolysis oil and gas products. In this study, the co-pyrolysis of Corn stover (CS) with plastic (LDPE, and PP) were studied through thermogravimetric analysis. The parameter “change in weight loss rate” denoted by ΔW was used to quantify the synergistic effects on the yield during co-pyrolysis. The ΔW values were fitted using a combined mixture design to generate an RSM model relating the factors mixture component proportions, plastic type, and temperature to the response ΔW. From numerical optimization, the obtained optimum co-pyrolysis conditions are: (a) 0.60 CS proportion, 0.40 LDPE proportion, and 481.73 ℃ temperature for CS-LDPE, (b) 0.68 CS proportion, 0.32 PP proportion, and 492.15 ℃ temperature for CS-PP. The activation energy, and pre-exponential factor of the reactions in the co-pyrolysis process were also obtained using direct solution method. The activation energy of the reaction that took place from 420 to 510 ℃ was found to be lower in the co-pyrolysis of Corn stover and plastic than in the pyrolysis of pure plastic.

Published: November 2022

Over the past few decades eutrophication of surface water has increased worldwide because of different anthropological activities including land fertilization and sewage run-offs; in combination with climate change. Excessive amount of nutrients (phosphorus and nitrogen), is now detected in freshwater lakes, artificially made reservoirs, and streams. Cyanobacterial nuisance in surface waters is among the most current environmental issues as it causes socio-economical problems. CYANOS is a two-year bilateral project funded from the Research Promotion Foundation of Cyprus and the Campus France of France with interdisciplinary activities that combines surface water monitoring and on-site water treatment for the restoration of eutrophic surface waters. Specifically, CYANOS aims to monitor the seasonal variation of cyanobacterial harmful algal blooms (cyano-HABs) in the surface waters of Cyprus and France and explore emerging on-site treatments to control their formation.

Published: November 2022

The adoption and enforcement of most conventions and regulations have been triggered by a series of disasters that had devastating effects on the marine environment. To improve the safety levels at sea and at the same time to protect the marine environment, it is imperative that the major shipping nations must ratify and make domestic law the international rules. Consequently, MARPOL, other conventions and codes refer to significant actions for minimising most pollution threats to the marine environment. So, member-states through their national ship-owners must comply with every new or amended regulation. This paper will focus on types of pollution that are not covered by any international legislation or are at a preliminary stage for future implementation. These types are: (i) Volatile Organic Compounds (VOC), (ii) Carbon Dioxide (CO₂), (iii) SOx Scrubbers Wash Water.

Published: November 2022

This paper reviews the use of remote sensing for practical applications in remediation of contaminated water and soil. Due to their flexibility of use, the Unmanned Aerial Vehicles (UAV) open interesting new prospects in the management of remediation of contaminated water and soil regarding various aspects such as sources of contamination, spatial dimension of contamination, level of contamination. However, the specificity of this kind of vehicles and of the sensors that they are capable to transport still requires detailed research work before making it fully operational for most of the unspecialized human resource existing in remediation of contaminated water and soil sectors.

In recent years, the technical-scientific community has been paying increasing attention to the presence of emerging contaminants that are intercepted in surface water and wastewater since these compounds could have harmful effects on human health and on environment too.
Conventional wastewater treatment installations represent a source of pollution from emerging contaminants because they are not designed to remove these compounds from the wastewater in their treatment cycle.
Several studies have shown the possibility of removing successfully these compounds from wastewater through the use of membrane bioreactors (MBR) combined with electrochemical processes, using conventional membranes.
The present study first examined the possibility of combining electrochemical processes with MBR (eMBR), through the use of self-forming dynamic membranes (SFDM) for the removal of emerging contaminants from municipal wastewater.
Thanks to this extremely innovative hybrid system, it has been possible to reduce the problems linked to the use of traditional membranes, in particular the high costs both of initial investment and of cleaning following fouling.
Particularly, the four most drugs used by humans representing different therapeutic groups, diclofenac (DCF) as anti-inflammatory, carbamazepine (CBZ) as anti-epileptic, amoxicillin (AMX) as antibiotic, estrone (E1) as sexual hormone and as a pesticide used in agriculture, atrazine (ATZ) it have been analysed.

Published: November 2022

Mediterranean (MED) islands and coastal areas are under pressure due to water shortage. Water reserves are depleted, while tourism in the summer months burdens the limited water sources. A persistent issue arising from the above activity is the increased seasonal loads of sewage that wastewater treatment plants (WWTPs) receive and need to cope with. On the top of that, the circular economy concept is not implemented in the MED region and particularly in small WWTPs. Water, nutrients, energy and chemicals contained in sewage are not usually valorized. At the same time, in several MED islands, energy intensive seawater desalination is applied to produce potable water thus increasing the energy demand and producing large quantities of brine water, which is not further valorized. As a consequence, activities within the concept of circular economy are required, considering the water-energy-food nexus. The HYDROUSA Horizon2020 Innovation Action project will provide innovative, regenerative and circular solutions for (1) nature-based water management of Mediterranean coastal areas, closing water loops; (2) nutrient management, boosting the agricultural and energy profile; and (3) local economies, based on circular value chains. The services provided lead to a win-win-win situation for the economy, environment and community within the water-energy-food-employment nexus.

Published: November 2022

The aim of the study was to perform extended monitoring of emerging contaminants in the water samples from three reservoirs of drinking water of EYDAP, Evinos, Mornos and Marathonas. Solid-Phase Extraction (SPE) by mixed-mode sorbent was used during the sample preparation to ensure the extraction of compounds with a wide range of physicochemical properties and very low limits of detection. The extracts were analyzed by complimentary chromatographic techniques, including Reversed Phase (RP) and Hydrophilic Interaction Liquid Chromatography (HILIC) coupled to Quadrupole-Time-of-Flight Mass Spectrometry (QToF-MS) due to its increased selectivity. Wide-scope target screening was performed by in-house databases consisting of 3,000 compounds, including several classes of emerging contaminants, naturally occurring compounds and endogenous metabolites. For the suspect screening, a database of approximately 40,000 compounds (REACH chemicals, industrial chemicals, biocides, PPCPs, surfactants and compounds from the NORMAN network monitoring programs) was used. Non-target screening was also performed for the identification of unknown unknowns in the analyzed samples.
Mobilisation of Arsenic in groundwater, Lesvos Island, Greece
Authors: ZKERI EIRINI , ALOUPI MARIA , GAGANIS PETROS
Published: November 2022

In the present study, a geochemical analysis was conducted to investigate the As occurrence and release in groundwater from two different geological environments on Lesvos island: (i) the volcanic area of Mandamados (ignimbrite) and (ii) the metamorphic area of Tarti that comprises the geologic basement under ignimbrite. Seven sampling campaigns were conducted between October 2010 and October 2011 including 65 groundwater samples from 11 wells and springs. Chemical analyses showed As concentrations exceeding the 10 μg/L national drinking water limit in 46% of the samples from Mandamados. Groundwater composition in Mandamados evolved from Ca-HCO3 type, to mixed type and finally to Na-Cl type along the groundwater flow direction, indicating the contribution of ion exchange in groundwater chemical composition, while Ca-HCO3 type waters were observed in the Tarti area. Arsenic speciation analysis showed that As(V) was the main species in all samples, indicating that As was released under oxidizing conditions. Statistical analysis suggested silicate weathering as the prime mechanism of As release in groundwater in both cases, while, in the Tarti area, carbonate dissolution may represent a secondary mechanism which could be related to the observed relatively low As concentrations in the region. In both areas, pH related desorption of As, primarily from Fe mineral phases, was found to be the most important factor controlling the mobilisation of As, while the contribution of the redox control to As release in groundwater was generally found to be less significant.
MODELING AND OPTIMIZATION OF TWO-PHASE OLIVE-OIL WASHING WASTEWATER PHENOLIC COMPOUNDS RECOVERY AND TREATMENT BY NOVEL WEAK-BASE ION EXCHANGE RESINS
Authors: Ochando Javier M. , Anotnio Martínez-Férez
Published: November 2022

In the present work, the concentration and recovery of high-added value phenolic compounds from two-phase olive mill wastewater (OMW) and the simultaneous effluent treatment by a ‘green process’ based on resins adsorption/ion exchange was studied. Olive oil is produced by a technological procedure based on physical operations, without use of chemicals. This industry is concerned to make the whole process environmentally friendly, which includes the treatment of the wastewater produced in the mills. The proposed weak-based IE process was statistically optimized and modelled. Results showed the resin performance was optimal at the raw effluent pH and ambient temperature conditions, which means no acidification or basification, nor cooling or heating would be needed. This would imply important savings for the scale-up of the process in real mills. The examined resin ensured minimum 72.4% phenols adsorption after 2 h contact time. The effluent could be partially discharged on suitable terrains or disposed to biological treatments, avoiding phytotoxicity or inhibition due to the phenolic content. The obtention of this concentrated pool of added-value antioxidant compounds for food, cosmetics, pharmaceutical and biotechnological industrial sectors could help counter-balance the economic feasibility of the reclamation process.
Climate Change and Security

Published: November 2022

Climate change is increasingly been called a ‘security’ problem, and there has been speculation that climate change may increase the risk of violent conflict. In this paper, the impact of climate change on the indicators such as war and insecurity, water and food resources, poverty development, migration, political and health borders and the spread of diseases that threatens human security, have been investigated. The result is that climate change is a global concern and requires global cooperation and accountability, especially in helping developing countries to adapt to its harmful effects. On a national level, all governments should establish a sustainable development ministry dedicated to managing the relationship between environmental change and human beings. On a global level, governments must ultimately realize that the treaties signed by all of them in the recent years on climate, environment and multi-state affairs are at least as much as the issue of global security and the size of all war zones and points.

Published: November 2022

The objective of this study was to investigate the accumulation of Se (IV) and Se (VI) and their effect on the growth of two unicellular photosynthetic algae, Chlamydomonas reinhardtii and Thalassiosira weissflogii. For this purpose, a cell growth rate experiment was conducted, in nutrient media spiked with several non-lethal levels of Se salts of both oxidation states, and the growth curves were constructed spectrophotometrically for all the conditions under examination. Cells were also grown in larger volumes in all conditions and the selenium contents of individual Chlamydomonas reinhardtii and Thalassiosira weissflogii cells were quantitated through the use of conventional ICP-MS and SC ICP-MS. Comparisons are being made between cell suspensions grown in different selenium salts in the two organisms. Our data show that the cell growth rates depend on the Se species (IV or VI) in the growth media. Similar observations were made with the Inductively Coupled Plasma – Mass Spectrometrry analysis regarding the accumulation of the different Se species in the cells.

Quasy eksperimental menggunakan desain kelompok kontrol pre-post test dan pengambilan sampel purposif yang dibagi menjadi 2 kelompok, kelompok intervensi dan kontrol dengan 17 orang setiap kelompok. Kelompok intervensi diberikan buah tin (Ficus carica) berdasarkan perhitungan dosis sesuai dengan konversi laurance, sementara kelompok kontrol hanya melakukan penarikan 24 jam sekali per dua hari. Hasilnya dianalisis dengan tes t berpasangan untuk menentukan perbedaan tekanan darah sebelum dan sesudah perawatan. Tes t independen dilakukan untuk menentukan perbedaan tekanan darah antara kelompok intervensi dan kontrol setelah perawatan. Buah tin (Ficus carica) memiliki efek pada pengurangan tekanan darah sistolik (p = 0,000) dan tekanan darah diastolik (p = 0,001). Tidak ada perbedaan yang signifikan antara kelompok intervensi dan kontrol (p = 0,599) pada tekanan darah systolik dan diastolik (p = 0,705). Buah tin (Ficus carica) dapat menurunkan tekanan darah, tetapi tidak ada perbedaan yang signifikan antara kelompok intervensi dan kontrol.
