Abstract. Bojonegoro faces flood every year with less advanced prevention development. Bojonegoro city development could not peak because the flood results material losses. It affects every sectors in Bojonegoro: education, politics, economy, social, and infrastructure development. This research aims to analyse and to ensure that river capacity has high probability to be the main factor of flood in Bojonegoro. Flood discharge analysis uses Nakayasu synthetic unit hydrograph for period of 5 years, 10 years, 25 years, 50 years, and 100 years. They would be compared to the water maximum capacity that could be loaded by downstream part of Bengawan Solo River in Bojonegoro. According to analysis result, Bengawan Solo River in Bojonegoro could not able to load flood discharges. Another method used is HEC-RAS analysis. The conclusion that shown by HEC-RAS analysis has the same view. It could be observed that flood water loading is more than full bank capacity elevation in the river. To conclude, the main factor that should be noticed by government to solve flood problem is river capacity.
Sampang is one of regency in Madura which always experiences floods every year. The frequency of flood events reach the number of 15 to 18 Sampang regency is divided into 6 watersheds that consist of Kemuning, Nedung, Blega, Samajid, Tambengan, and Tamberu watersheds events annually. From all watersheds, Kemuning watershed has the biggest area and become the priority in management of critical land management due to the impact of floods. The Length of Kemuning watershed is 54.11 kilometres with a watershed area of 354.50 km square consisting of 6 sub-districts, namely Sampang, Omben, Kedungdung, Robata, Torjun, and Camplong. The objective of the paper is to analyse the hazard index in Kemuning watershed, Sampang. The disaster hazard level is divided into 3 classes; low (hazard index <0.333), medium (hazard index: 0.333 - 0.666), high (hazard index> 0.666). The method used is a analysis which combines/overlays parameters of flood-prone areas and History of Flood Events data. The result is a flood hazard map that with details of 3476,18 hectare (51,71%) high level, 2614,37 hectare (38,89%) medium level, 631,61 hectare (9,39%) low level.
In recent years, Indonesia has experienced rapid increases in severe climate-related disasters have dramatically impacted populations unevenly; the poor and the vulnerable populations are most affected, and adaptive measures are urgently needed to protect and mitigate the impact on their health. However, very little is known about the existing measures addressing climate-related disasters and health impacts among vulnerable groups. WHO established a Health Emergency and Disaster Risk Management framework to urge governments and relevant actors to systematically collect evidence to develop science-based feasible adaptive strategies for priority groups. This study used scoping review methods to identify the action areas of Health-EDRM in policy documents in Indonesia, its content, and any potential gaps that require further study. The results from the documents’ review were then reported and discussed at a national stakeholder consultation meeting. This study has identified several achievements, lessons learned, and challenges from strategies and policies for health adaptation in facing climate-related disasters in Indonesia. This study also proposed strategies and recommendations to support mobilizing and accelerating health adaptation actions towards climate-related disasters in Indonesia.
Abstract. Jakarta has 10.2 million inhabitants. It has thoughtful problem about clean water availability. Today, only 54% of clean water availability could be supplied to citizens in Jakarta. The urgent need of new clean water resources is highly demanding for Jakarta future life. By employing abundant sea water in the northern part of Jakarta, desalination is a highly effective way that has been proven through value engineering. A conceptual design of desalination project is completed through FAST diagram and benchmarking method. According to life cycle cost analysis, it results IRR 13%, net product value Rp3.782 trillion, payback period of 13.39 years, and benefit cost ratio of 3.00. To make this project complete and reasonable, the public-private partnership should be conducted for modal sharing. This research piloted four analyzed scenarios. The best alternative scenario makes the government budget 60% for initial cost, spend half for operational and maintenance cost, and obtain 20% from the whole project revenue.
