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 appropriatetechnology-based countermeasures. The method that used in this research is a literature review, secondarydata collection, field observations and round table discussion. The result of this study is an analysis ofconstruction that solving deficit water conditions in districts of Karangmoncol , Purbalingga regency. Theconcept of construction proposed is implementation efforts are made especially for treatment with thetechnology of production ponds, ABSAH (Artificial Aquifer of rain water Deposit, Akuifer Buatan SimpananAir Hujan ) model . Karangmoncol District have problems in the availability of raw water, because well isvery 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 forArtificial Aquifer and Rainfall Storage (AARS). AARS is a result of modification of the well known rainfallharvesting storage tank (PAH) schemes. A guideline for designing this AARS has been accepted for solvingwater shortage problems elsewhere in Indonesia. This paper discusses the concepts and philosophy ofdesign and modification view points behind these new schemes. Based on population data 2350 person in535 household we taken 5 person every household. Everyday water demand calculated ais 125liter/man/day , so we should provide 625 liter/day every household. We have taken rainfall data inKarangmoncong district and it required 70 m2 roof area of the house for providing everyday needed byevery household. By the calculation of the dimensions as needed every day obtained the valid dimensionis 12m in length , 5m in width and 2.5m in depth.Keyword : Karangmoncol, Rainfall, population data, roof area, absah, harvesting rainfall storage

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.
