The implementation of decentralized system in 2001 has transferred the tasks to plan, execute and evaluate rural development to village government. Nevertheless, to be successful, decentralized system requires sufficient local capacity to implement these newly transferred tasks. This study aims to analyze the capacity of rural institutions, the realization of capacity to address livelihood problems and the effort of capacity development done by the government. It focuses on the four rural governmental institutions, namely village officers, neighborhood group, village parliament and village development committee. Case study was conducted in Serang, Kedarpan and Sumilir villages in Purbalingga District. Data were collected through questionnaires, interviews, observations and documentary studies. Totally 232 respondents were selected to provide perception on a set of capacity indicators of rural institutions. Among four levels of capacity set in this study, namely poor, slightly poor, good enough and good, this study finds that majority of the indicators fall under category of good enough. However, the realization of the capacity remains limited, and therefore only partial solution can be made to address local problems. Moreover, district government is so far emphasizing on capacity development for village officers, while neighborhood group, village parliament and village development committee were given less attention. Therefore, this study recommends the district government to conduct such effort of capacity development for neighborhood group, village parliament and village development committee.
Using the axe-bow to reduce total ship resistance on monohull ships has been well-known. This advantage has been further applied to a trimaran configuration together with its space-to-length (S/L) ratio differences. The investigation was carried out experimentally using an ITTC standard towing tank and numerically using computational fluid dynamics (CFD) analysis. The base model for the study uses an NPL 4a both for the mainhull and sidehulls of the trimaran, and later the mainhull is modified by attaching a front bulb known as an axe-bow. The resistance analysis of the trimaran was conducted with and without an axe-bow on the mainhull together with S/L ratios of S/L = 0.3 and S/L = 0.4 and at various Froude (Fr) numbers: 0.15, 0.2, 0.25, 0.3, 0.4, and 0.5. The results showed that the monohull with an axe-bow had a smaller drag than that without an axebow of an order up to 11.5%, whereas in the trimaran form, the reduction of drag was up to 8.4%. This indicates a positive influence of using the axe-bow on the total resistance of the trimaran configuration. Both experimental and CFD methods showed positive agreement of the order 2.7% discrepancy for the monohull form and a 3.4% discrepancy for the trimaran configuration.
This study aims to measure community membership in rural institution and analyze its benefits in rural development after Indonesian decentralization. To do so, a case study was conducted in Serang, Kedarpan and Sumilir village of Purbalingga District, Central Java Province. Respondents of this study consist of 232 people, and data are analyzed both qualitatively and quantitatively. Findings of this study present that diverse community groups exist, and most households become active members in one to two rural institutions. Neighbourhood, religious and farmer groups are the most active institutions in term of membership and carrying periodic meeting. Membership in rural institutions improves access to financial, physical and natural capital, but less in improving human capital. While most villagers are member of neighbourhood, farmer and religious groups, the village government does not build intensive interaction with these institutions in meetings to formulate village decision. Thus, the empowerment process is not optimally delivered, and the institutions cannot optimally help their members in addressing their livelihood problems. Some initiatives are performed by the institutions, but without government support, they result only limited benefits for the members. Thus, this study recommends the government to involve more institutions in village decision making, especially by improving the participation of neighbourhood, religious and farmer groups.
The use of propeller boss cap fins (PBCF) on open B-series propeller have been known to reduce wake effect behind the propeller thus increase torque and thrust of propeller, whilst the use of Kaplan-series propeller is successful to improve the quality of flow around the propeller blades hence increase the propeller efficiency. The current work is carried out to investigate the effect of combining PBCF and ducted on B-series and Kaplan-series propellers to discover further advantages of using the two types of energy saving device (ESD) tools. The study is carried out numerically using computational fluid dynamics (CFD) approach which is based on Reynolds-averaged Navier-Stokes Equations (RANSE) together with the use of k-epsilon turbulence modelling. Overall results show that the use of Kaplan-series with combination ducted and PBCF can even further improve the thrust, torque, and efficiency of propeller.
Research on the development of multihull vessels has investigated the breakdown of trimaran side hulls and produced a new type of vessel popularly known as a pentamaran. This study into the resistance characteristics of pentamarans was carried out using a towing tank belonging to the Institute Technology at Sepuluh Nopember in Surabaya, Indonesia. A test of trimaran resistance was included for comparison. The investigation focused on total resistance estimation and interference analysis for the two types of multihull vessels at separation-length ratios (S/Ls) of 0.2, 0.3, and 0.4. The dominant resistance value for the pentamaran was higher than that for the trimaran, with an average of 5.2%, due to the more complex interference between hulls. The average total resistance interference was 9.5% for the trimaran and 12.5% for the pentamaran.
Pertolongan kecelakaan penerbangan dan pemadam kebakaran (PKP-PK) merupakan unit bagian dari penanggulangan keadaan darurat di bandar udara yang memiliki standar teknis dan operasi yang telah diatur oleh regulator. Mengingat pentingnya peran PKP-PK di suatu bandar udara, maka maka sudah sepantasnya PKP-PK memiliki Personel yang kompeten di bidangnya. Hal tersebut dapat diperoleh melalui Pendidikan dan pelatihan yang diselenggarakan oleh Lembaga Pendidikan Penerbangan. Salah satu program pelatihan Basic PKP-PK oleh Poltekbang Palembang secara keseluruhan berjalan dengan baik dan lancar, dengan rata-rata nilai 83,46 (kualifikasi: baik sekali) dapat menjadi indikator bahwa tujuan pembelajaran telah tercapai.
