Abstract
One of the fundamental problems in the implementation of village development is related to the elements of village development planning or the preparation of Village Medium-Term Development Planning (RPJMDes) documents, because the RPJMDes is a document that shows the direction, objectives and policies of village development. RPJMDes is a document prepared by considering the objective conditions of the village and the development priorities of the district. The RPJMDes is prepared to be a systematic framework of thinking about the problems faced by villagers, about the potential sources of villages, as well as the formulation of strategic actions oriented to fulfill common ideals, namely improving welfare and at the same time building a democratic, fair and open (transparent) village government system or good governance. Jepitu Village is one of the villages located in Gunungkidul Regency, Yogyakarta Special Region which already has a RPJMDes for the period 2020-2025. This study aims to examine the suitability of the development planning process of Jepitu Village with selected reference documents. The method used was descriptive method. The results of the analysis of the Jepitu RPJMDes shows especially in the village development program, there is a discrepancy between the RPJMDes and the ideal rules of the RPJMDes regulated by government regulations.

Abstract
The emergence of smoke caused by forest and land fires has very specific characteristics because most of it is on peatlands. Efforts to prevent forest and land fires are essential considering the prevalence of forest and land fires in Kubu Raya Regency, West Kalimantan Province. Therefore, this study aims to analyze the spatial pattern of spatial modelling of forest and land fire hazard areas with the Hybrid Fire Index and determine the correlation between forest and land fire hazard areas and the function of forest areas in Kubu Raya Regency. The Hybrid Fire Index method is used to weight each variable used. There are two factors that affect forest and land fire hazard areas, namely topography and human activities. Based on the results of the raster overlay analysis with the Hybrid Fire Index weighting, it was found that Kubu Raya Regency is dominated by moderate-level forest and land fire hazard areas of 654,901.50 hectares or 76.55%. The results of spatial modelling of forest and land fire hazard areas have been validated with hotspots in 2021 using the AUC/ROC curve and the area under the ROC curve value is 0.862 which indicates that the score of this model is very good. The results of the nearest neighbor analysis show that the ratio value is more than 1, which means that the distribution of forest and high-level land and forest fire hazard areas has a spreading pattern throughout the district. The results of the chi-square statistical test of the hazard area with the forest and land area functions yielded a significant value of less than 0.05 with a contingency coefficient of 0.603, which means that there is a moderate correlation between forest and land fire hazard areas and the function of forest and land areas.

Abstract
Forest and land fires are events caused by both natural and human processes. Kubu Raya Regency, West Kalimantan is one of the districts that often experience forest and land fires. Generally, the forest and land fires are caused by human activities increase population density and land clearing through burning land. Forest and land fires in Kubu Raya Regency have caused environmental and economic damage, therefore it is necessary to identify the hazard areas for an effective management system to prevent more fires. This research aims to identify forest and land fire hazard areas and determine its relationship with concession areas in Kubu Raya Regency. Analytical Hierarchy Process (AHP) method is used to obtain the weight of each variable. There are three criteria that affect forest and land fire hazard area: topography, meteorology, and human activities, which consist of eight variables: altitude, slope, aspect, temperature, rainfall, wind speed, population density, and distance from the settlements. Based on the AHP calculation, the final weight of the topographic criteria is 0.11; meteorology 0.28; and human activity 0.62. This district’s forest and land fire hazard areas are divided into three classes: low, medium, and high. The weighted overlay result shows that Kubu Raya Regency is dominated by moderate forest and land fires areas, covering an area of 433.654,34 Ha or 50.7% of the total area. The second-largest forest and land fire hazard area are at a high level with an area of 244.282,41 Ha or 28.6% of the total area. The low forest and land fire hazard area has 177.624,25 Ha or 28.6% of the total area. The results fires hazards area were validated by hotspot data using the AUC/ROC curve and obtained an area under the ROC curve value of 0.76, which indicates moderate score of relationship.

Abstract
Surakarta is one of the big cities in Central Java and is the centre of the development of the mainstay area of SUBOSUKOWONOSRATEN. The physical development of the city of Surakarta has unwittingly spread to the periphery. The material changes in land use illustrate the expansion of the city of Surakarta and social and economic towards urban areas, called urbanization. Spatially, urban development in the suburbs of Surakarta City tends to the south or, in other words, towards Sukoharjo Regency. In line with the unstoppable pace of urbanization, Sukoharjo Regency must maximize development opportunities. The growth of urban areas can indicate urbanization. Industrial and residential growth can be an indication of urban growth. Urban growth modelling uses landusesim, GIS and Cellular Automata as the basis. Expectations of land use change are for industry to increase by 405 ha and settlements to increase by 2103 ha. The most significant land use change from 2022-2032 is in residential land use with an area of 1714.95 ha, which has changed from 2022 by 9%. Changes in land use for settlements are below the previously predicted expectations. Industrial land use also experienced changes in 2032; it increased by 405 ha or 48% from 2022.
The Vulnerability of Indonesian Smallholder Oil Palm Farmers in the Times of Global Crisis
Authors: Novira Nina 
Published: June 2023

Abstract
Since 2010, Indonesia has overtaken Malaysia as the biggest palm oil producer in the world. From around 12,7 million hectares of oil palm plantation spread across the country (2017), more than one third belonged to smallholder farmers. Almost all of those smallholder farmers do not possess any processing skill, thus they are dependent on oil palm mills to sell the fruit bunch. The export-oriented nature of palm oil resulted in the price fluctuation that follows global dynamics. With case studies in four villages in Labuhan Batu Utara Regency, this paper seeks to explore the awareness of how such conditions could impact the economic resilience of oil palm smallholder farmers during the global crisis and explore the near-future strategy to overcome it. The study used a qualitative approach using the in-depth interview to interview smallholder oil palm farmers, village officials, oil palm fruit middlemen, and related local government agency officials. The results show that smallholder oil palm farmers are most vulnerable in multiple aspects. The understanding of the relation of the price fluctuation to the global political and economical dynamics is gained through literature study. The lack of processing skills of farmers do not allow any possibility for an added value to the oil palm fruit, hence selling the fresh fruit immediately after harvest is the only option. Since selling is the only option, while on the other hand they do not hold any power to determine the price, little can be done when price slumps due to global dynamics. The farmers as well as the local leaders and government agency officials do not aware of the threat this may pose. Therefore, no agenda is currently set yet to strengthen the farmers’ resilience or in the near future.
Economic valuation of cattle farm development in Mondokan Sub-district, Sragen Regency
Authors: Irawan Sunu W J B , Sutrisno Djoko , Setyono Prabang 
Published: June 2023

Abstract
Agricultural development in Mondokan Sub-district encounters water scarcity which limits access to clean water for consumption and cultivation. This problem is exacerbated by shifting seasons due to global warming. The limited supply of water affects the cropping patterns of the community. Rice is planted in the rainy season and corn is planted inshifting between the dry and rainy season. Meanwhile, during the dry season, the field is abandoned. This cropping pattern has an impact on the economic level of the community. The dependence on cultivation as the main livelihood of the community needs to be solved through other alternatives, including animal husbandry. Cattle farm development in Mondokan Sub-district is supported by the environmental capacity of up to 9 million livestock units. However, the large capacity requires support in the livestock economy. The cattle farm development requires an economic valuation to obtain more significant benefits than cultivation. The economic valuation for the development of cattle farms employed the cost-benefit analysis method. The samples were farmers from Pare Village of Mondokan Sub-district who already have livestocks. The valuation assessment used the breeding system. The results of the economic valuation based on benefit and cost analysis indicate that cattle farming in Mondokan Sub-district is feasible.

Abstract
One of Indonesia’s regencies known for its agricultural land is Sukoharjo. The shortage of irrigation water has caused many problems in past years. The purpose of the research was to better understand the subsurface structure to increase the effectiveness of drilling in deep groundwater. Schlumberger’s configuration with a deep aquifer irrigation target zone was used to conduct the investigation. The track’s length is between 275 and 300 meters. Information obtained about the depth of the aquifer zone in the southern part of Sukoharjo is estimated to range from 4.83 to 155.79 meters. In the southern part of Sukoharjo, most of the ground cover consists of layers of sediment, limestone, and sandy clay.

Published: June 2023

Abstract

Background
Evidence on sleep duration or quality and cognitive function in diverse older adults is limited. We examined prospective associations between subjective sleep measures and cognitive function, with modifying effects of sex and age (&lt;65 vs ≥65 years).

Methods
Data are from the longitudinal Boston Puerto Rican Health Study, Waves 2 (n = 943) and 4 (n = 444), with mean follow-up of 10.5 years (range 7.2–12.8). Subjective measures of sleep duration (short &lt;7, ref. 7, or long ≥8 hours) and insomnia symptoms (sum of difficulty falling asleep, waking up at night, and early morning awakening), were assessed at Wave 2. Linear regression models were used to assess changes in global cognition, executive function, memory, and Mini-Mental State Examination, and tested for modifying roles of sex and age.

Results
Significant 3-way interaction (sex × age × cognition) in fully adjusted models showed greater decline in global cognitive function in older men with short (β [95% confidence interval]: −0.67 [−1.24, −0.10]) or long sleep duration (−0.92 [−1.55, −0.30]), compared to women, younger men, and older men with 7 hours of sleep. Insomnia symptoms were associated with a greater decline in memory (−0.54, [−0.85, −0.22]) among older men, compared to women and younger men.

Conclusion
Sleep duration showed a U-shaped association with cognitive decline, and insomnia symptoms were associated with memory decline in fully adjusted models. Older men, versus women and younger men, were at relatively greater risk for cognitive decline associated with sleep factors. These findings are important for personalizing sleep interventions to support cognitive health.

Authors: Toukach Philip V 
Published: June 2023

Abstract
Carbohydrate structures in the Carbohydrate Structure Database have been referenced to glycoepitopes from the Immune Epitope Database allowing users to explore the glycan structures and contained epitopes. Starting with an epitope, one can figure out the glycans from other organisms that share the same structural determinant, and retrieve the associated taxonomical, medical, and other data. This database mapping demonstrates the advantages of the integration of immunological and glycomic databases.

Published: June 2023

Abstract
Primary leptomeningeal melanoma is an extremely rare type of intracranial melanoma. It cannot be reliably distinguished from metastatic melanoma on neuroimaging and histopathological characteristics alone; its diagnosis is established only after exclusion of secondary metastatic disease from a cutaneous, mucosal or retinal primary. Prognosis is poor, partly due to its high rate of misdiagnosis. Herein, we report a case of a primary meningeal melanoma of the skull base with melanomatosis, in a 31-year-old man, mimicking meningioma. Our aim is to highlight the diagnostic pitfalls and to discuss the histopathological differential diagnoses, especially with other pigmented lesions of central nervous system.
UHECR echoes from the Council of Giants
Authors: Taylor A M , Matthews J H , Bell A R 
Published: June 2023

ABSTRACT
Recent anisotropy studies of UHECR data at energies ≳40 EeV have disclosed a correlation of their angular distribution with the extragalactic local structure, specifically with either local starburst galaxies or AGN. Using Monte Carlo simulations taking into account photodisintegration processes, we further explore a framework in which these UHECRs were accelerated by Centaurus A in a recent powerful outburst before being scattered by magnetic fields associated with local, Council of Giant, extragalactic structure. We find that the observed intermediate-scale anisotropies can be accounted for by the Council of Giant structure imposing a response function on the initial outburst of UHECRs from a single source located at Centaurus A’s position. The presence of these local structures create ‘echoes’ of UHECRs after the initial impulse and focusing effects. The strongest echo wave has a lag of ∼20 Myr, comparable to the age of synchrotron-emitting electrons in the giant Centaurus A lobes. Through consideration of the composition of both the direct and echo wave components, we find that the distribution of the light (1 &lt; ln A &lt; 1.5) component across the sky offers exciting prospects for testing the echo model using future facilities such as Auger prime. Our results demonstrate the potential that UHECR nuclei offer, as ‘composition clocks’, for probing propagation scenarios from local sources.
Exploring binary black hole mergers and host galaxies withsharkand COMPAS
Authors: Rauf Liana , Howlett Cullan , Davis Tamara M , Lagos Claudia D P 
Published: June 2023

ABSTRACTWe explore the connection between the gravitational wave (GW) merger rates of stellar-mass binary black holes (BBHs) and galaxy properties. We do this by generating populations of stars using the binary population synthesis code COMPAS and evolving them in galaxies from the semi-analytic galaxy formation model Shark, to determine the number of mergers occurring in each simulation time-step. We find that metal-rich and massive galaxies with star formation rate (SFR) greater than $1\, {\rm M}_{\odot }\, \rm yr^{-1}$ are 10 times more likely to have GW events compared to younger, less massive, and metal-poor galaxies. Our simulation with the default input parameters predicts a higher local merger rate density compared to the third GW transient catalogue (GWTC-3) prediction from LIGO, VIRGO, and KAGRA, due to short coalescence times, low metallicities, and a high SFR at low redshift in the simulation, which produces more BBHs that merge within the age of the Universe compared to observations. We identify alternate remnant mass models that more accurately reproduce the volumetric rate and provide updated fits to the merger rate as a function of redshift. We then investigate the relative fraction of GW events in our simulation that are in observable host galaxies from upcoming galaxy surveys, determining which of those are ideal for tracing host galaxies with high merger rates. The implications of this work can be utilized for constraining stellar evolution models, better informing follow-up programs, and placing informative priors on host galaxies when measuring cosmological parameters such as the Hubble constant.
ATRT-12. HYPERACTIVATING THE INTEGRATED STRESS RESPONSE WITH PROTEASOME INHIBITION IN AT/RT

Published: June 2023

Abstract
Atypical teratoid/rhabdoid tumor (AT/RT) is an aggressive pediatric brain tumor with a poor prognosis. AT/RT has increased baseline activation of the integrated stress response (ISR), an evolutionarily conserved system that enables cells to tolerate various forms of stress. Elevated expression of ATF4 indicates activation of the ISR. Transient or low-level expression of this transcription factor protects cells from stress, while sustained, high-level activation results in cell death. Ixazomib is an orally bioavailable proteasome inhibitor that causes endoplasmic reticulum stress, which is a major upstream activator of the ISR. Because AT/RT has a high baseline level of ATF4, we hypothesized that this tumor would be susceptible to ISR activators such as ixazomib. After determining the IC50 of ixazomib, AT/RT cell lines were treated with increasing concentrations of the drug. Cleaved caspase-3 immunofluorescence showed a significant increase of apoptosis (CHLA06 p&lt;0.0001 by ANOVA). We are currently testing ixazomib in combination with idarubicin, a brain-penetrant anthracycline, and gemcitabine, a brain-penetrant nucleoside analog. Synergy testing in CHLA06 showed an overall zero-interaction-potency (ZIP) synergy score of 23.464 with inhibitory concentrations of ixazomib and idarubicin in the low nanomolar range (scores of 10 or above indicate synergy). Similarly, ixazomib and gemcitabine synergized to suppress CHLA06 growth and induce apoptosis (67% Annexin V+ cells in combination compared to 14 and 24% Annexin V+ with single agent treatment). In the future, we will determine if ixazomib selectively kills AT/RT while sparing normal cells in iPSC brain organoids. We will also test ixazomib in orthotopic xenografts of AT/RT. These results suggest that ixazomib, especially in combination with idarubicin, gemcitabine or other ISR activators, has the potential to serve as an effective therapy for AT/RT.
