Rembang Regency is one of the regencies in Central Java that often experiences drought. Based on the results of the mapping of drought-prone areas for 2020 carried out by the Rembang Regency government, there are 63 villages spread across 14 sub-districts, 18,885 families are recorded as experiencing drought. Kaliori District is one of the sub-districts in Rembang Regency that is affected by drought, this sub-district consists of 23 villages and is directly adjacent to the north of Java Sea. The purpose of this research is to be able to do a mapping for planning sustainable drought solutions, obtain quantitative data on drought and stages of drought management. The stages of the research carried out were site surveys and interviews related to drought in the Kaliori area. Prior to the Focus Group Discussion (FGD), a questionnaire was prepared. This research was conducted through joint FGD with all village heads in Kaliori District regarding water drought in Rembang. Based on the FGD and the statistical analysis results, it was found that 70% of Kaliori District experienced drought. When there is a drought, generally villages in Kaliori sub-district use water from water tanks and some use wells of poor quality and having a salty taste. The majority of villages in Kaliori Sub-district experienced a drought that lasted for 4-5 months of a year. Several parties involved in dealing with drought in Kaliori Sub-district included PAMSIMAS, Karang Taruna, Banser, Paguyuban, and P3A. Some solutions proposed are river connection, estuary river gate, and reservoir optimation.

The objective of the study was to evaluate the capacity of Northern Bandung Dairy Farmer Cooperative (KPSBU) to support farmers in producing good quality milk within the milk value chain in West Bandung Regency, West Java. The study used qualitative research strategies including desk study, case study, and focus group discussions. The study compared the involvement of three milk collecting actors that were classified into large cooperative (KPSBU), small cooperative (KUD Puspa Mekar), and private company (Bina Kitri Bersama). A total of 18 dairy farmers, 3 milk collecting actors, 2 milk processors, and one livestock officer were interviewed. Three focus group discussions were conducted. The large cooperative performed better in services, milk collection, and milk quality assessment compared to other milk collecting actors. Members’ commitment, inconsistent milk quality, and shortage of good quality fodder were the hindering factors that influenced the collection of good quality milk in the large cooperative. In conclusion, the large cooperative had better performance in service provision, it also had better infrastructures in milk collection and milk quality assessment compared to other milk collecting actors. Increasing the milk quality standard by milk processing companies affected the milk price since 2000.

The Tuntang Watershed is an important watershed in Central Java. Management of watersheds in the Tuntang stream is a priority for various parties to carry out. One of the things that threatens the sustainability of the Tuntang watershed is erosion. The erosion rate can lead to sediment accumulation and siltation in the Tuntang River reservoir, which can cause catastrophic flooding. Flood disaster mitigation caused by erosion needs to be done, one of which is by calculating the erosion rate per year that occurs in the Tuntang watershed. This study calcultated the predicted erosion rate (per year in the Tuntang watershed) using the Revised Universal Soil Loss Equation (RUSLE) method, processed using the Google Earth Engine (GEE). Google offers a cloud-storage technology called GEE. Programming in JavaScript is required to operate GEE. GEE is a petabyte-scale data-based tool that can be used to analyze and archive geospatial data that is open source. The computing environment is designed for the processing of geospatial data, including the depiction of spatial analysis of satellite imagery. Data for RUSLE is obtained from the database in GEE, and the results can be imaged on a map. According to the study's findings, the degree of soil erosion throughout the Tuntang Watershed was essentially constant, with Moderate erosion predominating in the majority of locations. Senjoyo Sub Watershed, Rowopening Sub Watershed, and Tuntang Hilir Sub Watershed are the primary locations with severe erosion. Rowopening Sub Watershed is the region that is the worst.

SUMMARY Architecture compliance checking (ACC) is an approach to verify conformance of implemented program code to high-level models of architec tural design. Static ACC focuses on the modular software architecture and on the existence of rule violating dependencies between modules. Accurate tool support is essential for effective and efficient ACC. This paper presents a study on the accuracy of ACC tools regarding dependency analysis and violation reporting. Ten tools were tested and compare d by means of a custom-made benchmark. The Java code of the benchmark testware contains 34 different types of dependencies, which are based on an inventory of dependency types in object oriented program code. In a second test, the code of open source system FreeMind was used to compare the 10 tools on the number of reported rule violating dependencies and the exactness of the dependency and violation messages. On the average, 77% of the dependencies in our custom-made test software were reported, while 72% of the dependencies within a module of FreeMind were reported. The results show that all tools in the test could improve the accuracy of the reported dependencies and violations, though large differences between the 10 tools were observed. We have identified10 hard-to-detect types of dependencies and four challenges in dependency detection. The relevance of our findings is substantiated by means of a frequency analysis of the hard-to-detect types of dependencies in five open source systems. DOI: 10.1002/spe.2421

There is a clear demand for a collaborative knowledge-sharing on climate adaptation and mitigation. The aim of most climate adaptation platforms is (inter)national knowledge exchange and raising awareness about climate adaptation in urban areas and promote solutions such as Nature-based solutions (NBS) and floating infrastructure. However their multiple benefits are often unknown to the wider public. During seminars (February 2020) in Indonesia climate adaptation measures where mapped and the relevance of the climate adaption platforms such as ClimateScan was evaluated by the means of workshops and a survey. The platform ClimateScan holds now over 5000 locations in 5 main categories of climate adaptation (water, nature, agriculture, energy and people). The conclusions from the workshops in Semarang and Surabaya show high relevance scores for NBS: permeable pavement and swales; for infiltration of stormwater to groundwater; for mitigation of high temperatures with heat stress measures; and flood barriers to mitigate flooding. There were low scores for floating urbanization because this is not a culturally accepted practice in contradiction to other parts of the world. Indonesian floating infrastructure as a floating library, restaurant and airport terminal where mapped during workshops bringing the total of international floating structure locations to 150. The workshops have raised awareness among participants and contributed to capacity building by empowering the participants to map and review climate adaptation measures. A high majority see the value of climate adaptation platforms and will use it in the future.

Author supplied: Abstract—The growing importance and impact of new technologies are changing many industries. This effect is especially noticeable in the manufacturing industry. This paper explores a practical implementation of a hybrid architecture for the newest generation of manufacturing systems. The papers starts with a proposition that envisions reconfigurable systems that work together autonomously to create Manufacturing as a Service (MaaS). It introduces a number of problems in this area and shows the requirements for an architecture that can be the main research platform to solve a number of these problems, including the need for safe and flexible system behaviour and the ability to reconfigure with limited interference to other systems within the manufacturing environment. The paper highlights the infrastructure and architecture itself that can support the requirements to solve the mentioned problems in the future. A concept system named Grid Manufacturing is then introduced that shows both the hardware and software systems to handle the challenges. The paper then moves towards the design of the architecture and introduces all systems involved, including the specific hardware platforms that will be controlled by the software platform called REXOS (Reconfigurable EQuipletS Operating System). The design choices are provided that show why it has become a hybrid platform that uses Java Agent Development Framework (JADE) and Robot Operating System (ROS). Finally, to validate REXOS, the performance is measured and discussed, which shows that REXOS can be used as a practical basis for more specific research for robust autonomous reconfigurable systems and application in industry 4.0. This paper shows practical examples of how to successfully combine several technologies that are meant to lead to a faster adoption and a better business case for autonomous and reconfigurable systems in industry.

Many delta cities worldwide are dealing with the same kind of problems: rising of the sea level, land subsidence, scarcity of land and illegal housing. Multiple land use is one of these solutions that will help to reduce flooding and scarcity of land. An example of multiple land use is a floating community. This research used Semarang as location for the research into the social acceptance of floating houses. The data in this study were obtained through literature study and survey among inhabitants. The social acceptance of the inhabitants is determined with 35 respondents that have been done in the area of Kemijen, Semarang. In order to determine the social acceptance of floating houses, there are elements used, namely: knowledge of floating houses, perception of risk, urgency, implementation, chose for a floating house, requirements, positive and negative elements, self-sufficient system. According to the result of research, the social acceptance of the inhabitants is quite low, but there is potential because they see positive elements in a floating house. Low social acceptance is caused by the fact that the concept of floating houses is not well known in this community. With raising awareness on the challenges and informing the community on the possibilities on floating infrastructure will result in higher social acceptance.
