Urban region formation of small cities and the growth of urban settlements in peripheries: the case of Tegal and Pekalongan urban regions in Central Java, Indonesia

The expansion of urban areas has become spatial feature in the urbanization process of cities in Indonesia. As the most densely populated island in the world, Java has experienced such formation in both large and smaller cities. In most cases of expanded urban formations of small cities in Java, the formation has also created growing towns or urban settlements in the peripheries. Using the cases of the expanded urbanization process occurring in Tegal City and Pekalongan City, two smaller cities of Java whose urban areas have expanded into the territory of surrounding regency (regencies or non-urban districts), this paper aims to elaborate on an understanding of the extent of which the growth of urban settlements in peripheries in the expansion process of small cities. The research, which uses the territory of subdistricts to delineate the towns, tries to find how the spatial process affects the formation of urban regions as well as the towns in the peripheries. The analysis on villages’ transformation in peripheries was implemented by showing the spatial evolution of population density in the regions. Next, the development of towns in peripheries was analyzed to show the influence of such an urbanization process on the formation of towns in the peripheries of small or medium cities in Java. Time series and comparison analysis are employed to develop an understanding of how urbanization affects spatial formation in peripheries. The results show that the urbanization process of small cities needs to be managed in integrated manner so then the urbanization and peri-urbanization processes can be directed to produce better formation of the urban region.

PEMODELAN JUMLAH WISATAWAN DI JAWA TENGAH MENGGUNAKAN METODE GENERALIZED SPACE TIME AUTOREGRESSIVE - SEEMINGLY UNRELATED REGRESSION (GSTAR-SUR)

Space-time model is a model that can explain data with spatial and time characteristics. The Generalized Space Time Autoregressive (GSTAR) model is one of the generalized space-time models from the Space Time Autoregressive (STAR) model. The GSTAR model is more flexible when dealing with areas that have heterogeneous characteristics than the STAR model. The GSTAR model models time series data in multiple regions at once. This model can then be used to model data on the number of tourists in four regions in Central Java, namely Semarang, Jepara, Magelang and Semarang district for the 2014 to 2019 period. in Central Java. On the residual model, the Lagrange Multiplier Test is carried out and it is known that there is a correlation between the residuals. The modeling was continued by using the Generalized Space Time Autoregressive – Seemingly Unrelated Regression (GSTAR-SUR) model. GSTAR-SUR is one of the more efficient models used to model GSTAR with correlated residuals. Residual through the white-noise assumption test, it is found that the appropriate model is the GSTAR-SUR(2,1) model. This model can then be used in forecasting data on the number of tourists in Semarang, Jepara, Magelang and Semarang district in the next period

Daya Dukung Lahan Pertanian Di Kabupaten Kendal

Kendal Regency is one of the regencies in Central Java which is a center for rice production and has a fairly large area of rice fields. The study of the carrying capacity of agricultural land is very important because it is part of the study of the carrying capacity of the environment (D3TLH). Among the achievements of research on the carrying capacity of agricultural land, there has not been much discussion about the limitations and how to improvise the method. Therefore, this article will try to analyze and discuss the carrying capacity of agricultural land in Kendal Regency. The data used is secondary data from Kabupaten Kendal Dalam Angka. The results of the analysis show that Kendal Regency has a carrying capacity of 1.74 agricultural land which means a surplus. The limitation of this agricultural land carrying capacity analysis method is that it is difficult to model the carrying capacity of ecoregion-based agricultural land. Therefore, in the future work, we can build pixel-based data through remote sensing such as rice productivity extracted from the NDVI and EVI vegetation indices.

Associations among smoking, IDH mutations, MGMT promoter methylation, and grading in glioma: a cross-sectional study

Background Several molecular markers have important roles in glioma management. Mutations in the isocitrate dehydrogenase (IDH) gene are associated with the grading and prognosis of glioma. Methylation in the promoter region of the O (6)-methylguanine-DNA methyltransferase (MGMT) gene is an important determinant of glioma sensitivity to alkylating agents. Studies in various cancers indicated that IDH1 mutations and MGMT promoter methylations were associated with smoking habits. However, these associations in gliomas are still unclear. Accordingly, this study aimed to examine the association among smoking, IDH1 mutations, MGMT promoter methylation, and grading in glioma patients. Methods Patients were recruited from Dr. Sardjito General Hospital (a referral hospital in Yogyakarta and Central Java region) and its network hospitals. Genomic DNA was extracted from formalin-fixed paraffin-embedded samples or fresh glioma tissues. Identification of IDH1 mutation was performed using Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) or DNA sequencing. Methylation-specific real-time PCR was performed to identify MGMT promoter methylation status. Smoking status was obtained by history taken from the patient or family members. Results In total, 122 patients were included in this study. As many as 35 patients (28.7%) had a smoking history. Most smokers (57.1%) smoke less than ten cigarettes per day. However, most of them (68.8%) have been smoking for more than 20 years. Smoking patients have a significantly higher proportion of high-grade glioma than non-smokers (80% vs. 55.2%, p=0.01). Among 122 patients, 24 (19.7%) of them carried IDH1 mutation. Smoking patients have a significantly higher proportion of IDH1 mutation compared with non-smokers (31.4% vs. 14.9%, p<0.001). No significant association was found between intensity and duration of smoking with IDH1 mutations and glioma grading. No significant association was found between smoking and MGMT promoter methylation. Conclusions In glioma patients, smoking is associated with IDH1 mutations and grading but not with MGMT promoter methylation.

Penciptaan Konserto Etude Tangganada Pentatonik untuk Pembelajaran Violin dan Orkestra

The Creation of Pentatonic Scale Etude Concerto for Violin and Orchestral Learning. This research aims to explain creating a musical work in the form of a violin etude in the form of a concerto. The concerto is arranged in a free pentatonic scale from traditional Javanese idioms: the lancaran and gangsaran rhythm. The concerto consists of one movement that contains etude material, namely learning the technique of playing the violin in a beautiful and exciting melody. The problem highlighted is students' difficulty learning etude for the violin, which is often considered complicated. In the learning process, students tend to be oriented towards violin music such as concertos, sonatas, or musical pieces (short works) compared to etude works. Therefore, it is important for creating the concerto etude to bridge the students' violin learning process, both for educative and performative dimensions. Creating the etude concerto in this traditional idiom is expected to foster student interest in learning to practice etude. The research was organized in several stages: document collection, observation, artistic, trial, and dissemination. The research/design method was taken from Reginald Smith Brindle (1986), i.e., Musical Composition and King Palmer Teach Yourself to Composed Music (1952). The method is as follows: listening to different music that is close to the research topic to find ideas, using the violin and piano to make melodic pieces, including double, triple, four-stop techniques, connecting, combining, developing synchronized melody pieces, rhythmic variations, rhythms, articulation variations, syncopations, rhythm figures, melodic decorations, harmonies, dynamic variations, and so on. The conclusion of the research on creating a concerto with one movement is more freedom to express ideas. The use of lancaran and gangsaran rhythms in a pentatonic scale to give the nuances of the Central Java region, turns out to be more nuanced with a Mandarin concerto. After being implemented, it turns out that this concerto is still quite difficult for learning violin 3.

Tourism Village Carbon Footprint after COVID-19 Pandemic: A Challenge to Sustainability

The tourism industry is the most significant global Green House Gases (GHGs) contributor, which is often specifically produced by exploratory activities. This leads to the performance of several actions to reduce carbon emissions and maintain sustainable development. Since the Indonesian Tourism Village is a “carbon emission contributor and COVID-19 pandemic impact victim”, the low-carbon exploration should be necessarily implemented to achieve sustainability. Therefore, this study aims to determine the carbon footprint of solid waste produced by visitors, population, and buildings within seven certified Tourism Villages in Central Java (Kandri, Lerep, Samiran, Karangrejo, Candirejo, Samiran, and Dieng Kulon) and Special Region of Yogyakarta (Pentingsari) Provinces, Indonesia. This was conducted through a mixed method containing quantitative and analytical techniques. The quantitative method was conducted through a field survey of seven Tourism Villages to obtain and analyze data on the population, infrastructures, situations, and environments. Meanwhile, the analytical method was conducted by calculating the carbon footprint of solid waste and buildings produced by seven Tourism Villages. The results showed that Dieng Kulon had the biggest CO2 emissions from all sources (solid waste produced by visitors, population, and buildings). In addition, Candirejo had the lowest solid waste emission produced by visitors and the population before the impact of the pandemic. During the COVID-19 period, Kandri and Samiran were observed as the lowest contributors of solid-waste CO2 emission produced by visitors and buildings, respectively. This indicated that the sustainability of Tourism Villages helped in increasing income as well as obtaining a cleaner and healthier environment. After the pandemic period, these villages should subsequently lead the economic recovery of rural communities to achieve sustainable development goals through the reduction of CO2 emission. In addition, the “The Low-Carbon Sustainable Tourism Village Model” was proposed by this study to answer the challenge of sustainability.

RELATIONSHIP IN MOTHER’S PERSONALITY WITH HEALTHY BEHAVIOR IN AUTISTIC CHILDREN WITH CARERING MEDIATION IN THE TIME OF THE COVID-19 PANDEMIC

Healthy behavior implementation is a main priority during this Covid-19 pandemic, especially for children with autistic disorder. Children with autistic disorder have a high risk of transmission if there is no help associated with health problems accompaniment. The purpose of this study is to determine whether there is an effect of personality traits (extraversion, agreeableness, conscientiousness, neuroticism, and openness) on health behavior for children with autism, mediated by parenting in the COVID-19 pandemic. The study participants included 31 mothers who have children with ASD aged 6-12 years with the Mild - Moderately category who live in the Central Java region and are cared for by their mothers. The research method used is a quantitative method using path analysis as a data analysis technique. The research measurement tools used a scale of health behavior, parenting scale, and Big Five Inventory (BFI) scale. The Results of the study found that there was an effect of personality traits (extraversion, agreeableness, conscientiousness and openness) on health behavior in children with autism, mediated by parenting in the COVID-19 pandemic.

Seismic Imaging of Lithospheric Structure Beneath Central-East Java Region, Indonesia: Relation to Recent Earthquakes

The Central and East Java region, which is part of the Sunda Arc, has an important role in producing destructive earthquakes and volcanic complexes in Indonesia as a result of the convergence between the Indo-Australian plate that subducts under the Eurasian plate. In this study, the 3-D seismic velocity structure (Vp, Vs, and Vp/Vs) of the crust and upper mantle was determined to reveal the presence of the subducted slab, volcanic sources, and seismogenic features in the Central and East Java region. We have manually re-picked P- and S-arrivals of 1,488 events from January 2009 to September 2017 recorded at 27 stations of the BMKG network. An iterative damped least-squares inversion method was applied to simultaneously calculate both hypocenter relocations and velocity structure beneath this high-risk region to a depth of 200 km. We then compare the tomographic results and seismicity to interpret structural features in the seismic zones. The subducted slab is dipping toward the north, imaged by the high-velocity regions with low Vp/Vs at depths of about 50–100 km. Low-velocity anomalies with high Vp/Vs above the slab at a depth of ∼100 km, imply the possible location of partial melting from slab dehydration. Fluids and melts are ascending to feed the volcanoes i. e., Merapi-Merbabu, Wilis, Pandan, Semeru, Bromo, and Ijen that also have similar low-velocity anomalies at 10–30 km depths, suggesting the presence of the sedimentary basin or magma reservoir. We also have redetermined the hypocenter location of the 2021 (Mw 6.1) Malang earthquake at 8.94oS, 112.45oE, with a depth of 59.7 km. The location error in the x, y, and z directions are 3.08, 6.39, and 11.91 km, respectively. This intraslab event with a thrusting mechanism is located in the high-velocity region and close to the intermediate-depth seismic clusters, which indicates the geometry of the oceanic slab. In the region of 1994 (Mw 7.8) Banyuwangi earthquake, we found a low-velocity anomaly at ∼ 50 km depth that might be associated with the presence of subducting seamount that is more hydrated than the surrounding slab. The slip over this subducting seamount caused the tsunamigenic earthquake.
