Implementasi Peraturan Daerah Kota Semarang Nomor 14 Tahun 2011 Tentang Rencana Tata Ruang Wilayah Kota Semarang 2011-2031 (Studi Kasus Penataan Ruang Kawasan Simongan)

Landscaping area is the process of spatial planning and space utilization to control the development of the region. Spatial planning Semarang itself is set in Semarang City Regional Regulation No. 14 of 2011 on Spatial Planning Semarang City Year 2011-2031. Implementation of these regulations is difficult to do, as it happens in Simongan Region, District of West Semarang. Simongan region is mentioned as a settlement area of allotment, the trade and services and not as an industrial area. But in fact there are 12 companies located in the region. There is resistance from employers, factory workers and the public against this policy because the policy had an impact on the social and economic fields. Hampered by the problem of financial resources. However Semarang City Government still taking action to not issue a business license for industry in Region Simongan industry for entrepreneurs willing to relocate. There are several factors that affect the implementation of this policy, the resources, the strategy of implementing actors, characteristics of institutions and authorities, public response and target groups as well as compliance with the target group. It should be done reexamining the region by involving community, business, academia and experts structuring policy space in order to be accepted by all parties and in accordance with the existing problems at the site

The Effect of Fermented Oil Palm Fronds in Diet on Body Weight Gain and Meat Quality of Goat

The aims of study were to evaluate the use of fermented of oil palm fronds (FOPF) on body weightgain and meat quality of goat. This experiment was arranged in Completely Randomized Design with 3treatments i.e. R1 (grass 0%: FOPF 100%), R2 (grass 50%: FOPF 50%) and R3 (grass 100%: FOPF 0%)and 5 replications. The parameters of the study were feed intake, average daily gain (ADG), weight andpercentage of carcass and meat quality. The results indicated that feed intake and meat quality of goatwas not affected by treatment, but the average daily gain, carcass weight, and percentage of carcass, wasaffected by the differences of percentage of FOPF in the pellet complete feed. The best ration was in theR1 ration (grass 0%: FOPF 100%) that significantly different (P<0.05) from the other rations. The feedintake tended to be higher in goat fed R1 (895.87 g/d) compared to those in goat with the R2 (854.38g/d) and R3 (851.53 g/d). The average daily gain and carcass weight were higher in goat fed R1 rationcompared to those in goat fed R2 and R3. Consequently, the carcass percentage in R1 was higher thanthose in R2 and R3. The carcass percentage was ranged from 38.41-41.38%. The Ribeye area was higherin goat fed R1 (9.73 cm2) than R2 (8.34 cm2) and R3 (7.76 cm2). In this study, the protein content ofgoat meat was ranged from 19.06 to 20.71%, lipid content was ranged from 0.703 to 1.106% and watercontent was range from 72.45% to 74.12%, in which were not different among the treatments. It can beconcluded that the use of FOPF in a complete feed could improve performance and meat quality of goat

Flexural behaviour of plain concrete prism strengthened by textile fine grained mortar

This paper presents a flexural strength study of concrete incorporated with textile fine grained mortar (TFGM) as a strengthening laminate. TFGM is a combination of fine grained mortar (FGM) with alkali resistant glass fabric (AR glass). Fine grained sand with 600 m maximum size was used in FGM and fly ash (FA) or rice husk ash (RHA) has been used as a partial substitute for ordinary Portland cement (OPC). The potential of TFGM as strengthening laminate was tested under monolithic load with three point flexure loading. The TFGM were laid in layers of two, four, six, and eight. Results shown a promising flexure enhancement of up to three times of unstrengthened concrete when eight layers of both RHA and FA were laid. Load bearing capacity and ductility of the samples increased about 200% and 61%, respectively, compared to control samples as well. The outcome shows a highly potential use of agro-waste as cement replacement to produce load bearing structural component

Infantile acute megakaryoblastic leukaemia with T(1:22) in a non-down syndrome child.

Megakaryoblastic leukaemia is the commonest form of leukaemia occuring in Down syndrome infants. However, it’s subtype with translocation t(1;22)(p13;q13)is uncommon comprising <1% of all cases and reported to exclusively occur in infant without Down syndrome. It has a female predominance and carries apoor prognosis. We described this rare form of leukaemia in a 9-month-old girl who presented with bruises, massive hepatosplenomegaly and multiple cervical and inguinal lymphadenopathy. The blood film showed severe anaemia with ovalostomatocytosis, thrombocytopenia and mild leucocytosis. The bone marrow aspirate showed numerous blasts showing high nuclear-cytoplasmic ratio and agranular cytoplasm with cytoplasmic blebs. Peroxidase staining was negative. The immunophenotyping of the blasts showed positive expression of CD117, CD13, CD33 and CD61 which confirmed the diagnosis of acute megakaryoblastic leukaemia. Interestingly, the cytogenetic finding of translocation t(1;22) which is most common in acute megaloblastic leukaemia in infants without Down syndrome was found in this case. She received the AML trial 15 ADE protocol chemotherapy regime and developed severe neutropenic sepsis and respiratory distress requiring ventilatory support and granulocyte colony stimulating factor (G-CSF). She recovered wellmafter the first course of chemotherapy and was discharged. Unfortunately, she was not brought in for follow-up chemotherapy and presented a few months later with relapsed AML. She was re-started on ADE protocol and currently is on oral thioguanine for maintenance therapy

A model for ranking and selecting integrity tests in a distributed database

Checking the consistency of a database state generally involves the execution of integrity tests on the database, which verify whether the database is satisfying its constraints or not. This paper presents the various types of integrity tests as reported in previous works and discusses how these tests can significantly improve the performance of the constraint checking mechanisms without limiting to a certain type of test. Having these test alternatives and selecting the most suitable test is an issue that needs to be tackled. In this regard, the authors propose a model to rank and select the suitable test to be evaluated given several alternative tests. The model uses the amount of data transferred across the network, the number of sites involved, and the amount of data accessed as the parameters in deciding the suitable test. Several analyses have been performed to evaluate the proposed model, and results show that the model achieves a higher percentage of local processing as compared to the previous selected strategies
