Abstract

Selectivity of zeolite-lampung (ZKK) towards some matrices cations generated from uranium fission products has been investigated using some typical fission product-non-radioactive cations by cation exchange batch-system process. The previous investigation showed that zeolite-lampung is effectively able to absorb cesium ion from radioactive waste, consequently the presence of others cations i.e. generated cations from the uranium fission products are assumed as the competitive cations which may affect the zeolite selectivity on to Cs exchanges, on the otherhand the Cs-exchange capacity of zeolite would decrease. The main matrices cations which present in the natural zeolite are K+, Na+ and Ca2+and those are generated from fission products such as Cs+, Ba2+, Sr2+ and Ce4+ exist in the nuclear spent fuel solution. The ion exchanges of counterpart cations in zeolites with that each of Cs+, Ba2+, Sr2+ and Ce4+ ion or/and its mixtures have been examined. The selectivity of zeolite onto mentioned exchanged cations has been shown by the correlation of fraction of the cations concentration in the zeolite (Az) towards that in equilibrated solution (As). The results show that the raw zeolite Lampung selectivity is decrease in order to Cs+> Ba2+= Sr2+ > Ce4+. The exchanged capacity of zeolite into Cs+ ion is decreased by the presence of combining ions of Ba2+, Sr2+ and Ce4+, and so are those competitive cations.

Abstract

Village planning and budgeting in Indonesia is now reaping many problems, including human resources and the planning and budgeting model applied to several village heads in the country. One of the areas studied in Indonesia is Southeast Sulawesi Province with research locations in Muna Regency, namely 7 seaside villages and 8 non-seaside villages. This research aims to develop a collaborative mentoring model to improve the effectiveness of village planning and budgeting. This study uses a qualitative approach with a case study method in Muna Regency, Southeast Sulawesi, involving 15 villages with document analysis and in-depth interviews. Based on research that has been carried out, the village documents in Muna Regency already have village medium-term development plan documents, but most villages have expired village medium-term development plan documents. In addition, village assistance in budgeting has also not been maximized, such as the number of budgets in the field of community empowerment that are not planned in the deliberations of the village community development plan but then appear when the village revenue and expenditure budget changes and most of the activities are repeated for less than 4 (four) years. For an effective mentoring model in village planning and budgeting is the Stakeholders Collaborative Model in Village Planning and Budgeting in Muna Regency involving Ministries, Provincial Governments, Regency/City Regional Governments, District Governments, Village Community empowerment cadres and/or Third Parties.
