Published: June 2023

Abstract
This study was aimed to determine the land suitability class of fruit and vegetable crops which are potential to be developed in the lowland of Bintuni Bay. It showed that Manimeri is potential for the development of fruit crops (particularly orange and rambutan), and vegetables (greens mustard, long beans, chili). Based on actual land suitability, this area was categorized as marginal land (S3) with water availability, nutrient retention, and nutrient availability as limiting factors. Bintuni is potential for fruit crops (banana, durian, mango), and vegetables development (mustard, cabbage, long beans, spinach, eggplant, tomatoes, chili), which is categorized being quite a suitable land (S2), and marginal land (S3) with water and nutrient availability as limiting factors. Tembuni is potential to be developed with fruit crops (red fruit), and vegetables (mustard greens, long beans, pumpkin, and chili), and this area was categorized as a very suitable land (S1). Beimes is potential to be developed with pineapple and papaya with the land suitability class is quite suitable (S2). Mango, durian, green beans, chicory, tomatoes, and red chilies are less suitable because it includes marginal land (S3) with the limiting factors of root media, water availability, and low nutrients.

Abstract
The frost phenomenon that occurred over Jayapura, Indonesia, in July 2022 was the worst frost in the last two decades (1998 – 2022). The frost impact destroyed agricultural fields, crippling most of the crops, and caused famishing to hundreds of people. Because Jayapura has the largest agriculture field in Papua, an assessment of possible mechanisms that caused this extreme event is needed for disaster mitigation. On the other hand, numerous previous studies investigated the relationship between frost and climate change. However, it is still poorly understood, particularly in the Papua study case. This study explores the linkage between the frost phenomenon and climate change in Jayapura, Papua. Hence, we conducted an analysis using station observation and reanalysis datasets. In addition, we also assess spatial analysis to determine the distribution of weather pattern anomalies derived from The European Center for Medium-Range Weather Forecast (ECMWF) – ERA5 datasets during extreme episodes. We found that maximum and average temperatures have increased, while the minimum temperature has decreased over the last decade (2002-2022). It is also noted that the frost event may be related to temperature change in Jayapura, Papua.
Smoldering behavior of peat fire
Authors: Palamba P , Werdhani A S , Numberi J J 
Published: June 2023

Abstract
This research is conducted to study the effect of airflow rate on the smoldering combustion dynamics and transition to flaming. The test is done using three types of peat extracted from South Sumatera, Central Kalimantan, and Papua Provinces, Indonesia. The combustion is carried out on natural, 1.33 cm/s, 3.98 cm/s, and 6.63 cm/s of airflow, respectively, representing the oxidation with lack and excess of air as calculated by stoichiometric equilibrium. For Central Kalimantan and Papuan Peat, the smoldering spread rate tends to increase with increasing the air supply. While in South Sumatran Peat, it begins to decrease at the air velocity of 6.63 cm/s. Differences in physical properties yield the difference in the smoldering dynamic behavior. In general, a higher airflow velocity leads to higher smoldering temperature, spread rate, and mass loss rate. Combustion with natural air and lack of oxygen will result in smoldering whereas excess air led to a transition to flaming.
Enso and climate variability in Papua
Authors: Sarvina Yeli 
Published: June 2023

Abstract
The interaction of sea-atmosphere in the middle and east equators of the Pacific Ocean identified as El-Niño and Southern Oscillation (ENSO) is one of the interannual climate variability in Indonesia. Extremes phase ENSO, EL-Niño, and La-Niña have significant impacts on all sectors including agriculture, maritime, fishery, healthy, forest fire, transportation, etc. To anticipate ENSO impacts, it is required to identify the impacts of ENSO on climate variability in specific regions. In this study, we analyze the impact of ENSO on rainfall characteristics in several areas in Papua Islands namely Merauke, Jayapura, Manokwari, and Wamena. The result of the analysis reveals that the rainfall characteristics in Merauke, Jayapura, Manokwari, and Wamena are influenced by ENSO with different influences among areas. In general, onset of the rainy season is earlier in La Nina years in comparison to the normal year and the onset of the dry season is come in advance in El-Niño years. The annual rainfall in La-Nina year is higher than in normal years and El-Niño year is lower than in normal years. The anomaly of rainfall as impact ENSO varies differently among areas in Papua.

Abstract
The purpose of this study was to determine the extent of forest land change due to deforestation and forest degradation in Manokwari Regency as a development activity through land cover dynamics using satellite imagery data and make a land change prediction based on land change data analysis. This study used a descriptive method with an analysis of land cover changes using an overlay technique to determine land cover change. The results showed the change in land cover that occurred during the period 2009-2017 is dominated by changing of forested land to become settlement and plantation areas. The land cover has experienced a significant change in primary dryland forest, where nearly four thousand hectares of forest land have experienced degradation and deforestation. The land use prediction in 2025 was a reduction of the dry land forested area by about 9.1% while plantation and settlement were increased by about 4.5% and 2.0% respectively. Based on the comparison results, it was found that the predicted land use of Manokwari Regency in 2025 has land use suitability with the Regional Spatial Planning of 85.87%, not suitable at 6.8 %, and land use that allows for change at 7.33%.

Authors: Langi M A 
Published: June 2023

Abstract
The objective of this study is to tree biomass and forest carbon stocks contained in the Tangkoko Nature Reserve (TNR) of North Sulawesi. Phylogenetic diversity was analysed based on tree species composition weighted by aboveground biomass. A stratified systematic sampling was used in the study across transect lines. Field measurements follow the method described in the SNI 7724:2019 on ground-based forest carbon accounting. Based on allometric approach, this study produces a quantity of 255.45 Mg.ha−1 of total biomass estimation consisting of 201.14 Mg.ha−1 AGB and 54.31 Mg.ha−1 BGB. A standard approach of C-stock calculation (i.e. 47% of tree biomass and 50% of soil organic biomass) results in quantities of 94.53 and 27.15 Mg.ha−1 respectively). The importance of species traits for biomass estimation should be considered by initiatives in reforestation for carbon offsetting.
Potential carbon stock and environmental services in IUPHHK-HA PT Cenderawasih hijau letari, Kaimana Regency, West Papua Province
Authors: Hendri  , Moeljono S 
Published: June 2023

Abstract
Efforts to utilize natural resources are still constrained by activities that do not pay attention to the principles of sustainable environmental development. Various environmental disasters occur due to forest deforestation and degradation including floods, landslides, global warming, and further impacts on health. Thus, the role of tropical forests as a controller of environmental change is very important, including as one of the mainstay sectors in efforts to reduce the rate of emission (emitter) or the rate of carbon sequestration (removal) in an effort to meet the target of Nationally Determinant Contribution (NDC) in West Papua with a decrease of 29%. Greenhouse Gas (GHG) emissions from own efforts and 41% from international assistance. The supply of ecosystem services from the variety of unique and distinctive species and the computation of carbon potential in the absorption of GHG emissions are two environmental service activities that are currently the main emphasis. The allometric equation was used for carbon stock analysis from purposive sampling conducted at PT Cendrawasih Hijau. The results showed that the carbon potential from the aboveground biomass (AGB) and the belowground biomass (BGB) was 430 tons C/ha and 150 tons C/ha, respectively, respectively.

Abstract
KPHP Unit XIII Muaro Jambi as the forest management unit at site level has the potential as a large enough carbon sink. Given the area that reaches 107,839 hectares and has a type of peat soil, it is necessary to analyze carbon stocks in this forest area. Estimation of carbon stocks above ground level with non-destructive methods can be carried out using remote sensing technology by connecting the results of measurements in the field. Calculation of carbon stocks was calculated from biomass measurement in the field using allometric equations. The variables measured in this study were biomass stocks in sapling, pole, and tree stages. The data taken include data on diameter at breast height (DBH). The results showed that number of carbon stocks in 2022 in the sample plot based on the vegetation index (NDVI) class in KPHP Unit XIII Muaro Jambi from field measurements as follows: for sparse/low-density class, the average biomass is 23.27 tons/ha, the medium density class is 25.70 tons/ha. The last NDVI class, for the high-density class, the biomass stock is 74.62 tons/ha. Average biomass for all classes is 123.59 tons/ha and average of carbon content is 61.80 tons/ha.

AbstractBeside their role as carbon sinker, mangrove soil can also emit greenhouse gases (GHG) through microbial metabolism. However, their emission was scarce in every mangrove zone. We measured the CO2and N2O concentrations in Ngurah Rai Grand Forest Park, Bali, which experienced anthropogenic pressure.Rhizophora mucronataandSonneratia albadominated the mangrove vegetation in this area and have a characteristic zonation across the intertidal (landwards, middle, and seaward zone). Gas samples were taken above a height of 25 cm from mangrove soil during the wet season of 2020 at the three mangrove zones within three sites. Gas concentrations ranged from 303.09 – 330.57 ppm for CO2and 0.51 – 0.53 ppm for N2O. CO2and N2O concentrations were similar across mangrove zones, with a decreasing trend from the land toward the sea. A high density of mangrove trees was negatively associated with N2O; meanwhile, no soil and porewater parameters were significantly correlated with the gas concentrations. The result revealed that N2O concentration had exceeded the average value of the earth’s atmospheric N2O concentration. This information is essential for complementing previous research variations on GHG emissions and helps support the inventory of GHG emissions from the forestry sector.
Nutritional strategy underlying plant specialization to gypsum soils
Authors: Cera Andreu , Montserrat-Martí Gabriel , Palacio Sara 
Published: June 2023

Abstract
Gypsum soils are amongst the most widespread extreme substrates of the world, occurring in 112 countries. This type of hypercalcic substrate has a suite of extreme physical and chemical properties that make it stressful for plant establishment and growth. Extreme chemical properties include low plant-available nitrogen and phosphorus and high plant-available sulphur and calcium, which impose strong nutritional imbalances on plants. In spite of these edaphic barriers, gypsum soils harbour rich endemic floras that have evolved independently on five continents, with highly specialized species. Plants that only grow on gypsum are considered soil specialists, and they have a foliar elemental composition similar to the elemental availability of gypsum soils, with high calcium, sulphur and magnesium accumulation. However, the physiological and ecological role of the unique foliar elemental composition of gypsum specialists remains poorly understood, and it is unknown whether it provides an ecological advantage over other generalist species on gypsum soils. This article reviews available literature on the impact of gypsum soil features on plant life and the mechanisms underlying plant adaptation to gypsum environments. We conclude with a hypothesis on the potential role of the nutritional strategy underlying plant specialization to gypsum soils: Gypsum specialists primarily use SO42– as a counter anion to tolerate high Ca2+ concentrations in cells and avoid phosphorus depletion, which is one of the most limiting nutrients in gypsum soils.
Connectivity gradients in spontaneous brain activity at multiple frequency bands
Authors: Gong Zhu-Qing , Zuo Xi-Nian 
Published: June 2023

AbstractThe intrinsic organizational structure of the brain is reflected in spontaneous brain oscillations. Its functional integration and segregation hierarchy have been discovered in space by leveraging gradient approaches to low-frequency functional connectivity. This hierarchy of brain oscillations has not yet been fully understood, since previous studies have mainly concentrated on the brain oscillations from a single limited frequency range (~ 0.01–0.1 Hz). In this work, we extended the frequency range and performed gradient analysis across multiple frequency bands of fast resting-state fMRI signals from the Human Connectome Project and condensed a frequency-rank cortical map of the highest gradient. We found that the coarse skeletons of the functional organization hierarchy are generalizable across the multiple frequency bands. Beyond that, the highest integration levels of connectivity vary in the frequency domain across different large-scale brain networks. These findings are replicated in another independent dataset and demonstrated that different brain networks can integrate information at varying rates, indicating the significance of examining the intrinsic architecture of spontaneous brain activity from the perspective of multiple frequency bands.
Evolutive (Dynamic) Interpretation and Informal Modification of Constituent Instruments of International Organizations
Authors: Etinski Rodoljub 
Published: June 2023

Abstract
Induced by the work of the Institute of International Law on the limits to evolutive (dynamic) interpretation of constituent instruments of international organizations, the author discusses the issues of evolutive and dynamic interpretation, limits to the interpretation, legitimacy of informal modification of constituent instruments and borderline between interpretation and informal modification. He will propose conditions under which an informal modification may be legitimate. In spite of the fact that the borderline between interpretation and informal modification cannot be precisely located, the author will refer to certain judicial indications that its location may depend on the way by which a constituent instrument responds to the disputed issue. The author will turn attention, also, to the meeting points of judicial interpretation and informal modification.

Abstract

Background
Continuous evolution of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outpaces monovalent vaccine cross-protection to new viral variants. Consequently, bivalent coronavirus disease 2019 (COVID-19) vaccines including Omicron antigens were developed. The contrasting immunogenicity of the bivalent vaccines and the impact of prior antigenic exposure on new immune imprinting remains to be clarified.

Methods
In the large prospective ENFORCE cohort, we quantified spike-specific antibodies to 5 Omicron variants (BA.1 to BA.5) before and after BA.1 or BA.4/5 bivalent booster vaccination to compare Omicron variant-specific antibody inductions. We evaluated the impact of previous infection and characterized the dominant antibody responses.

Results
Prior to the bivalent fourth vaccine, all participants (N = 1697) had high levels of Omicron-specific antibodies. Antibody levels were significantly higher in individuals with a previous polymerase chain reaction positive (PCR+) infection, particularly for BA.2-specific antibodies (geometric mean ratio [GMR] 6.79, 95% confidence interval [CI] 6.05–7.62). Antibody levels were further significantly boosted in all individuals by receiving either of the bivalent vaccines, but greater fold inductions to all Omicron variants were observed in individuals with no prior infection. The BA.1 bivalent vaccine generated a dominant response toward BA.1 (adjusted GMR 1.31, 95% CI 1.09–1.57) and BA.3 (1.32, 1.09–1.59) antigens in individuals with no prior infection, whereas the BA.4/5 bivalent vaccine generated a dominant response toward BA.2 (0.87, 0.76–0.98), BA.4 (0.85, 0.75–0.97), and BA.5 (0.87, 0.76–0.99) antigens in individuals with a prior infection.

Conclusions
Vaccination and previous infection leave a clear serological imprint that is focused on the variant-specific antigen. Importantly, both bivalent vaccines induce high levels of Omicron variant-specific antibodies, suggesting broad cross-protection of Omicron variants.
When debates break apart: discursive polarization as a multi-dimensional divergence emerging in and through communication
Authors: Brüggemann Michael , Meyer Hendrik 
Published: June 2023

Abstract“Polarization” is a common diagnosis of the state of contemporary societies. Yet, few studies theorize or systematically analyze how polarization evolves in media content. To guide future empirical studies, we introduce a public sphere perspective on polarization. Discursive Polarization, defined as divergence emerging in public communication, may disrupt the public sphere if left untamed. Its analysis should combine the study of ideological polarization (increasing disagreement about issues) and affective polarization (growing disaffection between groups) as evolving in communication. Both processes may be measured in media content. We propose a framework combining the study of journalism and digital communication networks, investigating (1) content and (2) networked interactions regarding both political issues and social identity formation. The exploration of how the public sphere is disrupted in the process of Discursive Polarization may help us to understand the wider social phenomenon of polarization: before societies break apart, debates break apart.
Experiences of Hearing Children of Deaf Parents in Ireland
Authors: Heffernan Georgina , Nixon Elizabeth 
Published: June 2023

Abstract
Children of Deaf Adults (CODAs) are uniquely positioned at the intersection between Deaf and hearing communities and often act as interpreters for their parents and hearing individuals. Informed by previous research which has highlighted language brokering as a core element of CODAs’ experiences, along with the research which identifies the risk for parentification among CODAs, the aim of this study is to explore CODAs’ experiences of their roles within deaf-parented households and beyond the household, at the intersection between the Deaf and hearing worlds. Semi-structured interviews were conducted with 12 CODAs (Mean age 36.33 years, Range 22–54 years) in Ireland. Three themes were generated from the analysis of the interviews: “It was really normal”, Facing the Stigma associated with Deafness, and Being a Language Broker. The findings suggest that healthcare and education providers need a better understanding of the unique situations faced by CODAs in their roles as mediators between their parents and the hearing community, so that children and Deaf parents can be appropriately supported in their interactions with professionals.
