Building permit (Ijin Mendirikan Bangunan/IMB) is one of the development control mechanism inIndonesia that allows people to develop their land. The idea in using this permit to control developmentmay come from a reasonable thought, i.e. managing building as the core of urban development will be ableto create a proper urban planning. Therefore, as one of control system, building permit has to followregulations that have been determined by the authority.Concerning the issue above, Surakartaâ€™s municipality has determined a bundle of regulation functioned asguidance for permit decision into a municipal regulation (Peraturan Daerah/ Perda) as well as conventionregulation. That regulation control Building Coverage Ratio (Koefisien Dasar Bangunan/KDB), FloorAverage Ratio (Koefisien Lantai Bangunan/KLB), Set Back Building (Garis Sempadan Bangunan), andBuilding Height. Unfortunately, the implementation of that regulation is frequently questioned because theprocedure and the phenomenon of building permit which has been issued by the local government was noteffectively implemented. Hence, this study aims to answer the question on to what extent the buildingregulation has been used in controlong urban land development in Surakarta.This study uses comparative and qualitative descriptive analyses. The first analysis aims to observewhether that regulation have been considered in issuing a building permit. The second analysis is used toidentify how the factors above influence the implementation of that regulation. The triangulation techniquethat combines desk study, interview with the apparatus, questioners for IMB owners, and direct observationwas used to collect the data.The result of study shows that building permit was not issued based on the available regulation andmoreover not considered as a preventive action to control land development. The deviation between thedetermined ragulation and the building permit issued was affected by some factors, e.g. bureaucracysystem that does not use them as a control function to integrate permit decisions, low commitment of localgovernment staffs in controlling land development, and political intervention from its higher level of localgovernment authority. To overcome these problems, a brief regulation and a punishment mechanism arecertainly needed. Besides, improvement of apparatus quality, optimization of coordination and watchingsystem in building permit process are supposed to be able to support urban land development.

Publisher : Diponegoro University

In developing countries like Indonesia, the rationalization of production processes and systems will increase.Challenge that emerged significantly is the increase in planning efficiency. A prospective approach to reduce theplanning effort is the development of a production system capable of optimizing itself during the process. On theassembly line PT. Kubota Indonesia found that the workers perform assembly process with a sequence that is notplanned as a result of the lack of a standardized sequence of process companies and lead to cognitive controlthat are not stable and continuous learning process. Because this issue contrary to the concept of efficiency inplanning, it takes an automated system with a complete and fully optimized (self-optimizing production system).The purpose of this study is to apply the planning efficiency through implementation of optimized productionsystem (self-optimizing production systems) in assembly-line PT. Kubota Indonesia. Data obtaining done by thedetermination of primary and secondary variables include the perception of cognitive control, a solution basedon the memory (memory), and action. Repairs are carried out is by applying self-optimizing production systemconsisting of 4 steps: the development of cognitive architecture is to determine the sequence of work andapplying it to extend the software, implementation of individual modules is through the use of hand screw, thedevelopment of human machine interfaces in hand tool screw is through the explanation task analysis andimplementation and evaluation of improvement is the use of robotic assembly in the assembly processenvironment.

In our previous analysis of trusses, it was always assumed that the truss members are joined by ideal hingesand that loads are applied only at joints. The centroidal axes all of members are stright, coincide with thelines connecting the joint center, and lie in a plane that also contains the lines of action of all the loads andreaction. Thus the members of truss are subjected to axial force only, and these can be determined by staticmethod. A stress analysis base on these assumtion leads to the determination of so â€“ called â€œprimarystressesâ€.In actual cases the joint are usually riveted or welded; and because of this fact the members undergo, notonly axial forces, but also bending stresses from secondary moment, cuased by this condition are calledâ€œsecondary stressesâ€. In discusing secondary stresses we shall consider only trussses in one plane andassume that this plane represents the plane of symmetri for all members and that external loads are acting inthe same plane. Of these the most important are caused by the fact that the joint are rigid, and hence themembers are not free to change their relative directions when the truss is deformed. This problem canlikewise be solved very eficiently by means of moment distibution.From the first analyze result, it was obtained the scondary tension ratio with the primary tension at the pullshaft about 19.20 %. This result is significant that it will increase the existence of primary tension. At theanalyze by SAP 2000 is obtained that the end tension much more lower than the scondary tension in the firstanalyze. This is need to obtain attention at planning trusses.

Modeling and optimization methods are commonly used, still not able to model and optimize the complexchemical processes non-linear. Hybrid method of Artificial Neural Network-Genetic Algorithm (ANN-GA) isconsidered as an effective method for resolving these problems and obtain optimum conditions globally. Theaim of this study is to develop a modeling and optimization with hybrid ANN-GA methods, which applied inprocess of making glucose from starch hydrolysis. The ANN-GA stategy consists of two steps. In the first step,an ANN-based prosess model is developed. Therefore, the input at ANN model will be optimized using GAtechnique. The optimal values of starch concentration, enzyme concentration, temperature and time with ANNGAmethod were 7,13 % (w/v), 1,47 %(w/v), 40,53ÂºC, and 166,04 min respectively with predicted glucose yieldof 6,08 mg/mL. These result differed from the secondary data (Baskar et al., 2008) which were used RSM. Itwas because R2 values of ANN-GA method was 0,9755. While RSM method was only able to achieved value ofR2 for 0,842. Modeling and optimization with the GA-ANN can be developed and used to obtain the model instarch hydrolysis into glucose and the optimal operating conditions simultaneouosly.

The petroleum is the fuel derived from fossil which can not be renewable and the deposit in the earth is not morenow. In the middle 2008, the price of petroleum achieved US$ 147/Barrel because the supply of petroleum toworld market was reduced. This situation forced the appearance of the alternative energy which can replace thefossil fuel in the future. Their result of combustion has low emission so that they can be reduced the pollutionand were environment friendly. Biobriquette is the one alternative energy which expected to be able to replacethe kerosene and LPG. This research aims to get the exactly composition and type in manufacturing ofbiobriquette from cashew nut shell and jatropa shell waste. The variables choose as the independence variablewas the type of waste (cashew nut shell and jatropa shell) and the compositions (40, 60, 80 and 100%). Theothers are the fixed variable such as the size of briquette 4 cm and the total weight/biquette 25 g. The responseor parameters observed in the experiment were the color, the value of calor, the length of combustion and thecolor of fire. The result of experiment showed that composition of the material greatly affected the quality ofbriquette produced. The composition 100% owns the highest calor of combustion. The calor of Jatropa wastewas higher than that of cashew nut shell.

Roads that have poor surface roughness can cause uncomfortable to road users, traffic accidents, increase dynamic loads on the road surface, thereby accelerating the process of road damage, and damage to vehicles. This research aims to evaluate the stability of road conditions based on the international roughness index (IRI). Evaluation of road stability conditions was carried out on 14 road segments in the city of Yogyakarta, with details of four secondary arterial road segments and 10 secondary collector road segments. Data on road surface roughness (IRI) values were obtained using NAASRA roughness meter which refers to SNI 03-3426-1994. Evaluation of the stability of road conditions is done by comparing the IRI values of the survey results and the limits of IRI values determined by the Directorate General of Highways. The results showed that 14 roads were evaluated, 64% were in moderate condition and 36% were in good condition. Of the 14 roads, the Sisingamangaraja, Lowanu, and Sugeng Jeroni roads have the highest IRI value in a sequence so that the three road segments are prioritized for handling.

THE OUTBURST OF MODERN MARKET DEVELOPMENT (HYPERMART, MALL AND THE KINDS) Ediati, Murni

Publisher : Diponegoro University

Urban areas in Indonesia have tended to grow with little control or order in recent years, and this problemincludes the problem of modern markets. The emergence of modern market centers in Indonesia has given anew color to commerce activities. Opinions pro and contra have appeared about the emergence of thesecommercial centers. There are the various interests and needs of the actors such as investors, society, andgovernment in the emergence of malls, plazas, hypermarts, and groceries. The interests focus on the need toimprove tax revenue, regional compensation, inclusion of employees, improvement of trade, and the fulfillmentof people living standbards. Recently, the fast-growing modern markets have caused many controversies.However, government policies and decisions still support the emergence of such modern trade centers. Thesemodern markets compete with traditional markets. Although the traditional markets have their own marketsegments, modern markets should not allowed to wipe out them out. Based on these reasons, therefore, thegovernment should make strict, fair, and neutral regional policies (regional regulation) such as zoning rule andurban planning concepts for upcoming 50 years. Moreover, the government should improve the role oforganizers and urban planners as the managers, and enrich the market with pluralistic and comprehensiveconcepts sustainable development and social participation, something which is often neglected in urbanplanning.
