Primary data for the analysis were obtained by direct observation/survey at the research site in Jalan Abu Bakar Ali, Malioboro, and Solo in Yogyakarta City and survey of respondents of road users with questionnaires. Secondary data used to support the analysis are (a) road map and condition of around study sites, (b) assumptions in design standards, (c) standards on markers, signs, lighting, drainage, and (d) related study reports. The method of quantitative and qualitative analysis according to SLFJ and SRTH was applied rationally. It can be concluded that the knowledge and perceptions of respondents about the use of road space and environmental conditions around the road in the three locations was obtained in Good category with scores of 3.4; 3.52; and 4.2, respectively. In Jalan Abu Bakar Ali respondents responded Agreed (score of 4.18), meaning that it required additional facilities and maintenance of the RTH’s facilities and landscape. The management and maintenance of RTH's infrastructure and facilities of Jalan Abu Bakar Ali, Jalan Malioboro and Jalan Solo has been done by Yogyakarta City Planning Agency, organized and well-scheduled. Based on the evaluation of road functional requirement in Jalan Abu Bakar Ali (secondary collector), Jalan Malioboro (secondary artery), and Jalan Solo (secondary artery), all that are categorized as Conditional Function (LS). It means that the road has not fulfilled some road functional requirements in terms of utilization of road space, or there are still technical recommendations that must be met so that roads can be categorized as Function (LF). It obtained that Road Use Space (RUMAJA) is not effectively used, which characterized by still many permanent and non permanent buildings in the RUMAJA area. The design concept of the management and maintenance of road infrastructure should be based on the principle of maximizing road function (according to SLFJ) and the fulfillment of green open spaces on sidewalks and around (according to SRTH).","PeriodicalId":159255,"journal":{"name":"Jurnal Nasional Teknologi Terapan (JNTT)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115983196","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The selection of deep well water is preferred because the water quality is relatively better than the surface water. This condition causes PDAM to choose surface water such as river water as raw water, such as Progo water which is now used as alternative water for PDAM Kota Yogyakarta, PDAM Sleman and Bantul. Characteristics of surface water are generally poorer than ground water, this is due to more possibilities of contamination with pollutants resulting from human activities such as industry, agriculture and even natural events such as rain. It is physically easy to see that the surface water is generally cloudy compared to groundwater, since surface water generally contains mud and larger suspended particles. To reduce the mud content and suspended particles can be used coagulant material. There are many types of coagulant materials that we know such as alum (Alumunium Sulfate, Sodium Aluminate, Ferro Sulphate, Ferric Sulphate, Ferric Chloride, Lime and others). Technically coagulant capable of decreasing turbidity up to 0 NTU is Al2(SO4)3, combination between NaAlO2 and PAC, and combination between Fe (SO4) and PAC. Economically the cheapest coagulant is alum, with the optimum dose not much different but the purchase price is much cheaper than other types of coagulant.","PeriodicalId":159255,"journal":{"name":"Jurnal Nasional Teknologi Terapan (JNTT)","volume":"355 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132704124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the development of railway brake block material needs a device that capable of testing the characteristics of the brake block material. One of the important characteristics of the brake block material is the frictional characteristic. The method of testing the frictional characteristics of existing brake blocks include using the pin on disc method, direct testing on the railway and using a full-scale dynamometer. The full-scale dynamometer has advantages than other methods because it can test specimens according to the actual railway braking conditions in a short time and less preparations. However, with the same specimen size as the original, the cost of making the specimen and the full-scale dynamometer become expensive. Therefore, to reduce the cost of making device and test specimens, this study will design the dynamometer small-scale brake block testing. This paper use Pahl and Beitz design method which divides the design into four stages: clarification of the task, conceptual design, embodiment design, and detail design. This dynamometer is designed by considering function designs, structures, and forces that are adapted to the brake block contact pressure according to the original conditions. This dynamometer is designed to vary material, wheel speed, and contact presssure with the output of measurement of friction coefficient of brake block material. Brake block test specimens have a reduced size with a 1: 4 scale from their original size. The results obtained from this research are engineering drawings and dynamometer test model of railway braking.","PeriodicalId":159255,"journal":{"name":"Jurnal Nasional Teknologi Terapan (JNTT)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125606695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Land conversion which happens today has a negative impact on the environment and can damage the potency of the land use itself. One of the negative impacts of the land use conversion which are unwell planned, unwell patterned and not aware with the environment is the increased of the run-off volume due to the decrease the ability of the soil infiltration. If there is no further management of the land conversion, it will cause the increase of the annual peak discharge and has the potential to cause the flood. Green-Ampt is one of the method that can be used to analyze run-off volume by estimating capacity and infiltration rate. In Green-Ampt Method there are some parameters that affect the result of the analysis which are related to vegetal cover and soil parameters such as suction head, hydraulic conductivity, initial moisture, and saturated moisture condition of the soil. The aims of this study are to give the additional information and knowledge related to the run-off volume potency in the study area which has been conducted using Green-Ampt Method for the analysis. Hope the result can be used as the reference in management of water resources potency especially in study area, there are Sub Watershed Pogung, Kaloran and Papringan. From the analysis it is known that there is a different result between observed run-off volume and run-off volume by GreenAmpt Method. The difference of the result can occur because of the different intepretation data on both methods.
