The Potential Overview of PV System Installation at the Quarry Open Pit Mine PT. Bukit Asam, Tbk Tanjung Enim

South Sumatra has an established state-own enterprise exploring the Quarry Open Pit Mine. This mining process leaves some abondance open field that has a high potential to install a PV system. The Government has undertaken an initial analysis of 200 hectares of ex-mining land for this purpose. This paper analyzes the potential for PV panels to be installed at PTBA Tanjung Enim Quarry Open Pit Mine. The location of the PV panel in the open pit Quarry for this analysis is at an altitude of +140 m above sea level. Meanwhile, the PTBA Tanah Putih Township housing site where the PV comparison panel is installed is located on the altitude of +100 m above sea level, and within 2.97 km from the mine. PV panels installed in Open Pit mines generate better electricity and efficiency compared to PV panels installed outside the mine (in PTBA Township Housing). The difference of Isc between PV Panel installed in Quarry Open Pit Mine and Township is 0.0075 A. The Iload measured on the Quarry Open Pit Mine PV panel is 0.5478 A higher than the Township PV panel. Meanwhile, Voc measured on Quarry Open Pit Mine PV panel is smaller than Township PV panel, approximately 0.266 V and Vload of Quarry Open Pit Mine PV panel is 0.266 V larger than Township PV panel. The produced power of Quarry Open Pit Mine PV panel is 11.02 W larger than the Township PV panel. From the total value, the average efficiency produced by Quarry Open Pit Mine PV panels is 2.31 % higher than the efficiency produced by Township PV panels. This research shows the possibility and advantage of installing a PV system on a Quarry Open Pit Mine.

THE ROLE OF HOUSING MANAGEMENT AND STAFF IN ADMINISTERING THE R3 PROGRAM

Existing staff and management are central players in integrating enhanced services into affordable senior housing. This study describes the experience of housing providers in the implementation and operations of the R3 program. Semi-structured interviews were conducted with executives and direct service staff across the four intervention sites. Results indicate that staff served an important role in facilitating resident recruitment by operating as trusted sources of information about the R3 program. Top-level support for R3, acculturating R3 staff to the housing site, developing communication and data systems, and integrating new and existing staff were seen as crucial to the success of the program. Benefits noted by housing staff included freedom to redirect one’s energies/focus, production of actionable data/insights, reductions in resident turnover, and the addition of a nurse to the onsite services team. Housing management/staff experience with R3 can serve as a guide to moving to an enhanced services model.

Financing Informal Housing Provisioning in the Kumasi Metropolis of Ghana

Inadequate housing supply is one of the biggest challenges facing both developed and developing countries today with housingfinance being a critical factor. The informal sector is the largest housing supply system in Ghana but has not been able to meetthe increasing housing demand. This is partly because of inadequate and ineffective financial mechanisms for financing informalhousing provision in Ghana. The Study therefore investigated the major financing mechanisms used by the informal sectorand factors which hinder their access to formal credit facilities. A cross-sectional research design was adopted for the Study.Simple random sampling was used to select the ten communities whilst the convenience sampling method was used to select thehomeowners. A total of 310 interviews were conducted out of the total determined sample size of 392. The major findingsemanating from the Study included the dominant use of informal source of housing finance; the existence of an underdevelopedmortgage market; and uneasy access to formal credit facilities from financial institutions. These have led to homeowners buildingincrementally and hence delay in housing completion. The Study therefore recommends microfinance for housing, site andservices scheme and a non-mortgage lending facility for the informal sector.
