Generally, Central Java Province is quite prone to drought. Based on the balance sheet need’s water in 2020, Java will have a fairly large deficit in water demand. This study aims to overcome its conditions appropriate technology-based countermeasures. The method that used in this research is a literature review, secondary data collection, field observations and round table discussion. The result of this study is an analysis of construction that solving deficit water conditions in districts of Karangmoncol , Purbalingga regency. The concept of construction proposed is implementation efforts are made especially for treatment with the technology of production ponds, ABSAH (Artificial Aquifer of rain water Deposit, Akuifer Buatan Simpanan Air Hujan ) model . Karangmoncol District have problems in the availability of raw water, because well is very deep in the dry season. As an alternative can be taken the second highest value of ABSAH. In Indonesian, the schemes attributed to the so called ABSAH (Akuifer Buatan dan Simpanan Air Hujan), which stands for Artificial Aquifer and Rainfall Storage (AARS). AARS is a result of modification of the well known rainfall harvesting storage tank (PAH) schemes. A guideline for designing this AARS has been accepted for solving water shortage problems elsewhere in Indonesia. This paper discusses the concepts and philosophy of design and modification view points behind these new schemes. Based on population data 2350 person in 535 household we taken 5 person every household. Everyday water demand calculated ais 125 liter/man/day , so we should provide 625 liter/day every household. We have taken rainfall data in Karangmoncong district and it required 70 m2 roof area of the house for providing everyday needed by every household. By the calculation of the dimensions as needed every day obtained the valid dimension is 12m in length , 5m in width and 2.5m in depth.

Mojokerto is one of the leading regions in East Java Province This of course has consequences for growth in all fields, especially industry and housing. So that it will have an influence either directly or indirectly on the growth of other supporting facilities growth in various fields leads to increased demand for water due  to climate change, several springs in Mojokerto district have decreased by 60% from their original condition. This study aims to predict future water needs with the influence of changes in population, the effect of increasing the number of industries and facilities, both commercial and non-commercial using a dynamic system so that it can be used as a basis for water resource management decisions. In analyzing a complex system that works with real conditions, it is very risky and costly, therefore we need a model that can represent the conditions of the existing system. The stages in the research are as follows: 1. Secondary data collection in the study area which includes: Population data, data on the number of public facilities, data on the number of hotel rooms, data on the number of hospital rooms, data on rice fields, data on the number of livestock, data on the area of tourism and data on the number of markets; (2) Data Analysis; (3) System Dynamic Analysis;(4)Simulation of water demand prediction in the study area;(5) Model validation with the structure validation test and the AVE and AME validation tests. The simulation model for the prediction of water demand in Mojekerto Regency based on a dynamic system is declared valid because it has fulfilled the structure test and validation test both AVE and AME From the results of the scenario simulation applied, it was able to save water by 30% for domestic water needs and 92% for non-domestic water needs. It is necessary to make a model to determine the availability of existing water resources so that a model of water resources balance in Mojokerto Regency is compiled.

Abstract Background Minimally invasive esophagectomy (MIE) is a complex and technically demanding procedure with a long learning curve, which is associated with increased morbidity and mortality. To master MIE, training in essential steps is crucial. Yet, no consensus on essential steps of MIE is available. The aim of this study was to achieve expert consensus on essential steps in Ivor Lewis and McKeown MIE through Delphi methodology. Methods Based on expert opinion and peer-reviewed literature, essential steps were defined for Ivor Lewis (IL) and McKeown (McK) MIE. In a round table discussion, experts finalized the lists of steps and an online Delphi questionnaire was sent to an international expert panel (7 European countries) of minimally invasive upper GI surgeons. Based on replies and comments, steps were adjusted and rephrased and sent in iterative fashion until consensus was achieved. Results Two Delphi rounds were conducted and response rates were 74% (23 out of 31 experts) for the first and 81% (27 out of 33 experts) for the second round. Consensus was achieved on 106 essential steps for both the IL and McK approach. Cronbach’s alpha in the first round was 0.78 (IL) and 0.78 (McK) and in the second round 0.92 (IL) and 0.88 (McK). Conclusions Consensus among European experts was achieved on essential surgical steps for both Ivor Lewis and McKeown minimally invasive esophagectomy.

Background: Eye health has garnered increased attention since the COVID-19 pandemic. This Round Table explored the impact mask wearing, delays in eye examinations, and increased screen time have on vision and ultimately the worker. Methods: Leading experts in the areas of occupational health, risk management, eye health, and communication were identified and invited to participate in a Round Table discussion. Questions posed to experts were based on literature that addressed eye health, such as mask wearing, communication and managing expectations when accessing professional eye health appointments, and increased screen time. Findings: Experts agreed that eye health considerations must be in place. These considerations should address not only clinical care of the patient but ways to protect workers from occupational injury associated with the eye. Conclusion/Application to practice: The occupational health professional is a key resource for assessment and training that pertains to eye health.
