Abstract
Zeolites are crystalline aluminosilicates usable for numerous applications, including in the separation or purification gas processes, catalysts, ion exchanger and adsorbent. These benefits are due to their molecular sieve property. One of the appropriate technologies for the peat management related to C sequestration and potential peat fire suppressor is molecular sieve material, i.e., zeolite-clinoptilolites and other gas adsorbent material taken from empty fruit bunches of oil palm (EFBOP) obtained through the pyrolysis process (biochar). This study assessed the physicochemical and morphological characterization of natural zeolite-clinoptilolite type, originated from Bayah, Banten, Indonesia, and biochar as gas adsorbent to minimize greenhouse gas emissions and C sequestration. Physicochemical characteristics of 60-80;80-100, 100-150 particles mesh size of zeolite and biochar were measured according to standard analytical procedures based on Kepmentan 261/KPTS/SR.310/M/4/2019. Mineralogical characteristics and the capacity to absorb greenhouse gasses (CO2 and N2) were determined using SEM-EDS and Brunauer-Emmet-Teller analysis, respectively. The result indicated that 100- 150 mesh zeolite had a higher CEC value (126.45 cmol(+) kg−1), CO2 (1.0586 mmol g−1) and N2 adsorption capacity (75.6 cm3 g−1), compared to biochar originated from EFBOP 26.9 cmol(+) kg−1; 0.071 mmol g−1; and 1.66 cm3 g−1, respectively. Biochar observed in this research yielded a higher pH and organic carbon content, with larger pore space. Combining zeolite and biochar provided an optimal result to deplete greenhouse gas emission i.e., 0.3662 mmol g−1, and improved water retention as indicated by water holding capacity percentage.

Abstract
Greenhouse gas (GHG) emissions from peatlands are influenced by many factors and most of them are difficult to control. Soil temperature and moisture regulate biological reactions in the soil leading to gas production. It is a complex mechanism, considering the difficulty in controlling soil moisture and temperature. The study aimed to assess the consequence of soil moisture and temperature alteration on Carbon Dioxide (CO2) emission through water level management. Soil samples were collected using a 21 cm (diameter) and 100 cm (length) of polyvinyl chloride (PVC); each was dipped into big bucket to control water level. Water levels were controlled in daily basis. Three different water levels were arranged, i.e., at 15 cm, 35 cm and 55 cm beneath earth surface and were replicated 3 times. The results showed that water levels affected soil and water temperature. Non-linear relationship between temperature and CO2 emission (P < 0.01) was discovered in this research. The lowest soil moisture was recorded at -55 cm water level below surface, then by experiments at -35 cm and -15 cm water levels. Lower water level increased aeration of peat soil and created optimal conditions for microorganisms to oxidize organic matters that produced and emitted CO2 into the atmosphere.

Abstract
Soils in riparian swampland are considered marginal and have low nutrient contents. A research on the validation of fertilizer recommendations as a complement to Swamp Soil Test Kit (PUTR) was carried out on shallow inland swamps in Sungai Ambangan Village, Sungai Raya District, Kubu Raya Regency, West Kalimantan, during dry season of 2017. The treatments consisted of 1) complete control; 2) NPK local recommendations; 3) 1 1/2; of NPK PUTR recommendation + Dolomite; 4) NPK PUTR recommendation + Dolomite; 5) 2/3 of NPK PUTR recommendation + Dolomite; and 6) NPK of local farmer’s recommendation. Results using PUTR and laboratory equipment showed acidic soils with low to medium nitrogen, medium to high P, and low potassium. Validation showed that highest number of productive tillers was found in treatment of 1 1/2; of NPK PUTR recommendation + Dolomite. Plant height showed that there was insignificant difference between treatment with NPK local recommendation, 1 1/2; of NPK PUTR recommendation + Dolomite, NPK PUTR recommendation + Dolomite, 2/3 of NPK PUTR recommendation + Dolomite. This was similar to results of harvested dry grain and harvested grind grain. Utilization of PUTR as rapid test tool can be implemented for ricultivation on riparian swampland. Impact of fertilization obtained neck blast attack increased along with the rise of fertilization dose, especially nitrogen.

Abstract
Soybean is one of essential food crops targeted for self-sufficiency. Indonesia’s largest oil palm plantation is located in Riau Province. Juvenile plants cover around 17.60 percent of the area. Soybeans can be intercropped with juvenile oil palm plantations. This study aims to determine the suitability of peatland in Muara Kelantan Village, Sungai Mandau District, Siak Regency. We collected data and information from primary observations, measurements, and from published articles recording secondary data including rainfall, annual temperature, and map of the research area. Soil type was classified as Typic Haplosaprist. Land suitability was determined by matching collected data with criteria for each class, resulting the class of marginal (S3), with base saturation and soil acidity (nr) as limiting factors. Lime and fertilization were required to increase base saturation and soil pH. After the improvement, the potential suitability becomes sufficiently suitable (S2) for intercropping between soybean and juvenile oil palm, with the air humidity (tc) and peat thickness (rc) as limiting factors.

Abstract
Peatlands are considerably vulnerable and fragile. Despite this, peatlands serve as a place to live and to exercise sustainable farming for some communities. This study aims to examine the potentials of peatland in Tanjung Jabung Barat Regency for agricultural activities. Peatland distribution map with scale of 1:50,000 and the unanimous map on forest functions (TGHK map) are the main sources for this study. Laboratory analysis over seven soil samples were used for the assessment of land suitability, before overlaid with TGHK map to determine potentials and availability of lands for agriculture activities. Results showed that only 20,285 ha were suitable for agricultural activities. About 18,433 ha peatlands were classified as marginally suitable (S3) for food crops or horticulture, while the same level of suitability for annual crops occupied around 20,142 ha. Main limiting factors in land suitability were root condition (rc) due to deep to very deep peat depth categories; and nutrient retention (nr) due to high soil acidity. Utilization of peatlands for agricultural activities needs to appropriately conserve pristine condition to allow sustainable environment in the long term while maintaining and economic benefits. This research suggests that local water management, liming, fertilizer and minimum tillage would improve the quality of peatlands.

Abstract
Rice fields in Talio Hulu Village, located in the Swamp Irrigation Area (SIA) Block B Pangkoh I, Pandih Batu District, Pulang Pisau Regency, Central Kalimantan is cleared peatlands which replanted with rice afters being abandoned for years. This paper is a review of peatland research and development in Talio Hulu Village. This paper aims to provide an overview of sequential changes of peat soils since its opening in 1983, being developed by planting rice and secondary crops, subsequently abandoned, and afterwards managed and replanted in 2020. Soil chemical properties and fertility in 1987 showed that the top layer (0-30 cm) and below (>30 cm) were very acidic (pH 3.3-3.9); C-organic 36% and 53%; N total 2.3% and 1.2%; low base cation exchange capacity, and P2O5 1.4 mg kg−1 and 0.43 mg kg−1, then the plant showed less than optimal growth. The identification of chemical properties and fertility of the top and bottom layers of the soil after rice development in 1993 showed improvements, including: decreasing soil acidity with pH H2O 3.4-4.4 and 3.3-3.7; C-organic decreased to 11.46% and 54.52%; N total 0.33-1.11% and 0.48-1.53%; P2O5 7-100 mg kg−1 and 10-15 mg kg−1. Rice yields reached 0.3-2.0 t ha−1 for local rice varieties and 0.2-2.4 t ha−1 for high-yielding varieties. The low yield of rice indicated the poor growth of rice plants measured from the high amount of empty grain. From the survey in 2020, we identified 80% of rice fields were categorized as peat and 20% as shallow peat (peat layer <100 cm). After land remediation, soil acidity decreased (pH increased) at pH 4.11 and 4.47, C-organic decreased by 34.89 % and 42.48%, P-available increased to 17.90 mg kg−1 and 22.88 mg kg−1, and no more deep peat was found. Meanwhile, rice productivity increased to 1.55-6.31 t ha−1 or 3.27 t ha−1 an average.

AbstractThis paper assesses the condition of a 45 years old precast reinforced concrete multistorey building and proposes innovative repair techniques for extending its service life. The residential building investigated consists of six floors, and each floor consists of 4 apartments with a total floor area of 900 m2. Initially, visual inspection was conducted to identify the extent of deterioration in all parts of the building, followed by field non-destructive and destructive tests to determine the root causes of the damage. Moreover, analytical tools such as ETABS and SAFE design softwares were used by applying the same loading assumptions and material properties given by the designer, to check the compliance of the building with the safety requirements specified in ACI 318-14/SBC 304-18 building codes. The field and laboratory checks confirmed the occurrence of considerable degree of deterioration in some elements of the building due to reinforcement corrosion, alkali silica reaction (ASR), salt–scaling and leaching. The analytical checks revealed excessive deflections, due to a design error. Several advanced repair techniques including carbon fiber reinforced polymer sheets (CFRP), and steel jackets were implemented to restore the structural load carrying capacity of the columns and beams that suffered extensive deterioration. The excessive deflections were reduced below the code limit by supporting the deflected slabs using wide flanged I-section steel beams. Moreover, the Repair strategy proposed included, removal of the deteriorated concrete, coating the exposed steel bars with a protective anti-corrosive coating, and cathodic protection of the steel bars followed by injecting high strength cementitious grout.

Abstract
Rapid urbanization and population migration encountered in developing countries results in an increasing need for transportation. To investigate the impact of vehicular emissions on air pollution/quality and respiratory health we conducted a comparative 2:1 cross-sectional study in rural and urban communities, 150 adult respondents and 30 children comprised the study population. Structured interviewer administered questionnaires; Clinical respiratory examination and digital Spirometry were conducted. Informed consent was obtained; data were analyzed using Epi info statistical software version 7. Results showed Mean age: (36.3± 12.9 years), Linear height: (median 1.65, range: 1.40 – 1.86). Adult Male: female ratio 1:1. Average Distance of households to roads/highway: 36.03±23.79 meters and prevalent duration of daily transit 2- 5 hours. In urban settlements: distance to highway/road <50 meters (OR 32.4, 95% CI: 8.57- 122.3) and Non-use of protective devices (OR: 12.43, 95% CI: 2.60-59.34) showed significant associations. Twenty two (22) Spirometry results were within the obstructive index. Abnormalities detected on Spirometry in the absence of a history of respiratory conditions or abnormalities on clinical chest examination require further investigation. Recommendations were targeted to improve health education, provide sustainable mass transit, urban planning, support focused research and ensure effective emissions control.

Abstract
Tuscany, with its mixed geology, offers a great variety of stones that are used to build entire villages. In this paper, two of these building materials are considered: Rosso Ammonitco and Pietra Serena. In particular, the activity concentration of 226Ra, 232Th and 40K have been analysed in order to estimate the value of the gamma index. In addition to this, the X-ray fluorescence spectroscopy has been carried out to obtain a chemical characterization of the stones. Although these kind of stones are not subjected to radiological characterization, the approach used was the one reported in Radiation Protection 112, also implemented in the Italian Legislative Decree 101/2020, because of their lithographical peculiarity and their employment in construction.

Published: July 2022

Abstract
Anthropogenic pollutants get into the environment not only with untreated sewage but can also migrate with treated municipal sewage. Examples of such contaminants are UV filters (BP-3, EHS, EHMC, OC), synthetic volatile fragrances (AHTN, HHCB), and microplastics. In the case of these pollutants, it is necessary to intensify the treatment of municipal wastewater and introduce pre-treatment or additional wastewater treatment; constant monitoring of concentrations in surface and marine waters, sediments, and tissues of aquatic organisms; assessment of transformations and interactions with other pollutants in seawater and assessment of changes in conditions unfavorable for their degradation. The seas and oceans are the dumps where these pollutants eventually get it.

Authors: Zhao Puyang , Tian Wei 
Published: July 2022

Abstract
In this paper, we use the methods of machine learning and traditional time series to predict solar power generation, which is based on the Australia Market Data. In the paper, we analyze Ausgrid's Solar by using long and short-term memory (LSTM) methods and time series models (multiple regression models with related errors) to accurately estimate the parameters of photovoltaic (PV) array models, which is using the data of household electricity consumption from July 1, 2010, to June 30, 2013. The results show that the regression model with correlated errors is better than the machine learning-based LSTM algorithm, which is based on the differential MSE performance. The final prediction accuracy rate is as high as 98%, so the regression model can accurately predict solar power generation.

Published: July 2022

Abstract
A The motion response of floating wave energy converters (WEC) is crucial for study in the field of ocean energy harvesting. A well-known design for gathering ocean wave energy is the floating wave energy point absorber. It is commonly investigated theoretically using idealised one- and two-degrees-of-freedom dynamic models based on the system's number of free bodies. Using Computational Fluid Dynamics (CFD) software, this article evaluates the hydrodynamic damping of heaving motions on cylinder and conical two-body point absorber wave energy harvesters. The damping performance of both point absorber devices in the Sarawak zone was evaluated using a simulation run at low wave heights (0.25m-2.25m) and short wave periods (3.5s-9.5s). Both point absorber bodies are modelled to determine their heaving dynamic motion frequency under calm, medium, and strong wave conditions. This analysis reveals the extensive research being undertaken to advance point absorbers' technical maturity, ultimately paving the way for commercialization and mass production. The results reveal that a cylinder two-body point absorber with a Response Amplitude Operator (RAO) is more efficient than a conical point absorber at absorbing low wave heights.
A Zero-injection Initialization Numerical Method for Ill-conditioned Power Flow
Authors: Zhang Shuiping , Li Shun , Luan Tianrui , Chen Yixing , Li Suirong 
Published: July 2022

Abstract
Regarding the initial value sensitivity issues commonly found in Newton-like power flow calculation algorithms, a zero-injection initialization numerical method for ill-conditioned power flow is proposed in this paper, which improves the convergence of power flow calculation in ill-conditioned power systems. Based on the initial power flow provided by this method, the unbalanced active power of each bus (the slack bus excluded) relates to the net injection of active power of that bus and the unbalanced reactive power of each PQ bus relates to the net injection of reactive power of that bus, thus avoiding significant power unbalance. The method put forward herein can provide a reasonable initial value for the power flow calculation so that difficulty in power flow convergence caused by the unreasonable initial power flow is effectively avoided. The Newton’s method and the optimal multiplier method are implemented respectively on a small-scale ill-conditioned test system to verify the feasibility of the proposed zero-injection initialization numerical method.

Published: July 2022

Abstract
This research investigates the economic and environmental impact of various suitable biogas conversion technologies and their energy utilization options (electrical and thermal) on cassava pulp treatment. The results showed that the anaerobic cover lagoon (ACL), modified cover lagoon (MCL), and anaerobic baffled reactors (ABR) were the most suitable options in terms of the investment cost, which was the major factor influencing the selection of biogas technology. The ACL and MCL technologies had the highest values of NPV, a high IRR and a short payback period regardless of the energy utilization options due to their low investment and operating costs.
Tailor-Tuned Nanoparticle-Based CoOx/Pd Electrocatalyst for the Direct Glycerol Fuel Cell
Authors: El-Nowihy Ghada H. 
Published: July 2022

Abstract
A glassy carbon (GC) electrode decorated with an efficient nanoparticle-based electrocatalyst of palladium (nano-Pd) and cobalt oxide (nano-CoOx) is electrochemically prepared and examined towards glycerol electro-oxidation (GO) for direct glycerol fuel cell (DGFC) applications. The activity of the tailored electrode toward GO depends on the catalyst components and loadings onto the GC surface. Cyclic voltammetry (CV) technique is used to evaluate the electrocatalytic activity of the introduced catalyst toward GO. Field-emission scanning electron microscope (FE-SEM) and X-ray diffraction (XRD) are used to disclose the morphology and the crystallographic structure of the surface, respectively. CV measurements depict that the oxidation peak current (I
p) of GO obtained at CoOx/Pd/GC electrode (where nano-Pd is first electrodeposited at GC surface followed by nano-CoOx deposition) is almost double the value obtained at Pd/GC electrode (where nano-Pd is electrodeposited at GC surface), concurrently with a significant cathodic shift in the onset potential (E
onset) of GO ≅ 80 mV. As well, CoOx/Pd/GC electrode shows a good stability towards GO with continuous electrolysis. It also shows an enhanced catalytic activity towards other alcohols oxidation (i.e., methanol and ethylene glycol) when compared to Pd/GC electrode.
Determination of The Thermal Lethality Distances Generated by The Radiative Flux Emitted by The Di-Tert-Butyl Peroxide (DTBP, C8H18O2) Fireball: Use of Characteristic Curves
Authors: Mbarki Anas , Ettahir Aziz , Guelzim Abderraouf 
Published: July 2022

Abstract
Di-tert-butyl peroxide or DTBP is a very dangerous organic peroxide, widely used as a modifier, cross-linking agent and polymerization initiator in the industry. Its widespread use pushes us to set up studies assessing the dangers of this product, since it has been at the origin of Bleve explosions producing fireballs with a very devastating power and thermal effects. The hazard studies of this product remain very minimal. Our work consists in determining the thermal effect distances of a resulting fireball during the rupture of a DTBP storage tank, based on the characteristic curves of the thermal doses deduced from the specific model of P. Blankenhagel modeling a fireball of an organic peroxide. The authors propose a new graphical method that allows to efficiently determine the hazard zones of the effects of thermal doses, and consequently, the delimitation of the safety distances in case of an accident Bleve. The adequate utilization of this method can improve the response time of first responders in disaster areas to set up safety zones and evacuate people, and at the same time improve the safety of a large number of facilities.

Published: July 2022

Abstract
In the aim of reducing the effect of climate change on the environment, multiple energy efficient solutions have been developed in all energy-consuming sectors around the world, especially smart building design strategies in the building sector. One of these technologies are Ventilated Double-Skin Façades (VDFs), which use the thermal interaction between the external environment and the internal space of a building in order to reduce its heating or cooling loads and thus reduce the greenhouse gas emissions. They also offer multiple other benefits, depending on several parameters, including improving the building’s thermal and acoustic insulation, and providing natural ventilation and exposure to daylight. The goal of this paper is to provide a review of the available research on VDFs in literature, namely their thermal behavior, the parameters that influence it, and the main criteria used to categorize VDFs.
