The utilization of village-information system for integrated social welfare data management: actor-network theory approach in Gunungkidul regency

As the main reference to poverty alleviation in Indonesia, the policy of integrated welfare data management by the Ministry of Social Affairs still contains many inaccuracies. This has an impact on beneficiary groups as the target of the implementation of national programs on poverty reduction. This study shows how Integrated Social Welfare Data management by the local government in Gunungkidul Regency, Special Region of Yogyakarta, can solve the inaccuracy. The analysis was conducted with qualitative methods, based on actor-network theory. Data collection, verification, and validation are processed by integrating Village Information System (SID BERDAYA) and Regency Information System (SIKAB) in Gunungkidul at the local level, with the Social Welfare Information System - Next Generation (SIKS-NG) by the Ministry of Social Affairs in national level. This integration is needed to improve the quality of data accuracy and validity. Strengthening the participation and transparency of social interaction between government agencies at every level (from the village level to the national level) and the community people are important since communities are the beneficiaries. These processes will develop a reflective scheme, to make sure the quality of planning and development program on poverty alleviation is running with accurate and valid data.

Analysis of ceiling type to produce energy efficient residential buildings: case study on housing design of puskim pu-bandung city

Many houses that exist on this earth. Therefore, it is necessary to have tactical and intelligent thinking in designing a home. Many things are rarely considered related to the effects of the design of building elements when related to the temperature or the energy produced. Existing background regarding efforts to reach a comfortable temperature can not only be solved in terms of mechanical systems, but the architectural approach can help and provide a comfortable effect for its inhabitants. This research was conducted to determine the level of thermal comfort or temperature in the room of a residential design that would be related to the size of energy consumption by applying several alternative designs or ceiling forms. This type of research is research using simulation methods through a computer model. The results showed the use of ceiling type Vaulted Ceiling was able to increase the Surface Inside Temperature value by 3 ° C when compared to the type of drop ceiling. The Mean Radiant Temperature value when using the ceiling vault type rises 0.6 ° C and on the acquisition of Operative, Temperature rises 0.3 ° C. The use of insulation material on the roof can significantly reduce Mean Radiant Temperature and Operative Temperature at 1.7 ° C at Mean Radiant Temperature and 0.8 ° C at Operative Temperature. Seeing the results of the simulation in this study, the recommended ceiling type is to use the drop ceiling type because it is quite capable of keeping the temperature in the room not too high so that thermal comfort can be achieved. However, if you want to apply a ceiling design with a model or type of drop ceiling, it is better to use additional insulation material so that the heat transmission temperature is not too high in the room.

Urban tourism space based on bike-sharing tourist in Yogyakarta city

This paper identifies the urban tourism space in a complex way as chosen by the bike-sharing tourists in Yogyakarta. The space is defined as not only the tourist attraction object which has become a common attraction but also the elements of urban architecture such as landmarks, districts, paths, edges, and nodes that becoming lanes, stop points, and the destination for the tourist when cycling around using bike-sharing. The data collecting used in this research is person-cantered mapping by following the bike-sharing tourists’ movement and giving questionnaires to find out the tourists’ motivation in using bike-sharing for tourism. The hypothesis shows that the tourists would prefer to choose the common attraction as an urban tourism space in Yogyakarta. But by cycling, the tourists will be able to seek a new experience because they can be more flexible in exploring the space with uniqueness which has the shape of urban architecture elements. The research results showed that landmarks and paths were the two urban architecture elements that gave strong characteristics toward urban tourism space, as preferred by the bike-sharing tourists in Yogyakarta. The tourist attraction with both characteristics was located around the city centre. It indicated that the distribution of visits is still centrally located close to the bike shelters. So that the tourists could go to the other unique destinations in Yogyakarta, thus the researcher recommends that the bike shelters need to be evenly spread approaching the tourism attractions and amenities.

Employing lipase of candida antarctica (calb) as catalyst in the acetylation of para-aminophenol in aqueous and water-free medium

Candida antarctica lipase B (CaLB) is one of lipase classes enzymes that has many advantages to be used in the process of synthesizing organic compounds. In this study, some experiments were conducted to examine the ability of CaLB as a catalyst in the para-aminophenol (PAP) acetylation to produce paracetamol as the result. Two types of research have been carried out, the first one is to utilize CaLB to catalyze acetylation of PAP in a water-free reaction medium, and the second one is to use CaLB as catalyst in aqueous medium through oxidative amidation reaction. Reaction in water free system was held in ethyl catalyst acetate as solvent that also act as the acyl donor, while in the aqueous medium, acetylacetone was used as acyl donor and ethyl acetate as source to produce peracid that will be used as oxidator. Analysis was done by HPLC and TLC densitometric to follow the amount of paracetamol produced. The results of CaLB-catalyzed acylation in water free system showed that the enzyme could accept PAF and ethyl acetate as a substrate in a nucleophilic substitution reaction, resulting in paracetamol as a product. However, the yield from the acylation of PAP is still not satisfactory. In the reaction in aqueous medium, CaLB has been proven to show its activity to catalyze the acylation of PAP with acetylacetone, as well as the reaction of peracid formation from ethyl acetate. The results show that this strategy can work well and give better yields than the other reaction in water-free medium.

Determination of the convective heat transfer constant (c and n) in a solar still

The geometry of a solar still determines the convection constants C and n, which in turn affect the convection heat transfer coefficient’s value and mass. A method for determining the value of convection heat transfer constants C and n has already been developed by the researchers. Therefore, this study aimed to use several methods and theories to find the value of convection heat transfer constants C and n. The results are then compared with the results of the study. The solar still used in this study has one slope. To reduce variables that cannot be controlled, the data collection was conducted indoors using a halogen lamp that can be regulated as a heat source for 24 hours nonstop. The sea surface height in the solar still was maintained at a height of 20 mm, using a height regulator. Temperature was measured using a data logger set to enter data every hour. The desalinised clean water was stored in bottles placed on scales that were recorded every one hour. Room temperature was maintained in the range of 35 to 36 oC. The data in this study were used to calculate the heat transfer constants C and n to obtain the value of the convection heat transfer coefficient and mass calculation. This study compares the calculation models of Tiwari, Dunkle and Power. The following calculation model results: Tiwari model, C = 0.082 and n = 0.612; Dunkle model, C = 0.075 and n = 1/3; Power model, C = 0.815 and n = 0.611. The C and n values obtained with these four approaches reveal that the results from the Power model calculation are the closest to the actual mass, showing a percentage deviation of 1.63%.

Pemanfaatan citra kamera inframerah thermal (kit) untuk mendeteksi area inflamasi pada tubuh manusia

Inflammation is an indication of an abnormality in the human body. Cases of inflammation occur accompanied by changes in temperature on the surface of the body. The location and location of the spread of inflammation cannot be seen solely by the human eye in detail. An imaging modality tool that is suitable for use in observing this problem is needed. In this study, the Thermal Infrared Camera (TIC) is used as an imaging modality. Samples in the form of a pair of legs in which one part of inflammation occurs are used as research objects. TIC is an imaging modality tool that can detect temperatures on the surface of an object quickly and is nondestructive. The results of the TIC image are processed using the global thresholding image processing method to distinguish between the inflammatory areas and normal areas more specifically. The results displayed indicate that there are differences in the image between the area of inflammation with the normal area of the patient's feet. The results of image processing data in the form of binary images show between the inflammatory area represented by white and vice versa the normal area represented by black. A comparison between the two conditions of the patient's feet before and after recovery shows the shrinkage of the area. There are two main results obtained in the exploration of this research, which is successful in distinguishing the inflammatory area from the normal area and the progress of recovery from the legs of the affected patient.
