The prevalence of risk factors and symptoms of mental-health problems has been found to be higher in urban than non-urban areas. However, most studies are conducted in developed countries, and we are unsure whether a similar pattern can be observed in a developing country. In the present study, we compared rates of common mental health risk-factors and symptoms of psychosis, depression, and anxiety between urban and non-urban residents. A community sample of 844 participants completed an anonymous cross-sectional online survey. T-tests and Mann-Whitney U Test were used to compare participants’ scores on mental health-risk factors and symptoms based on their area of residence. Our analyses showed that participants living in urban areas experienced a higher frequency of loneliness, being bullied at home, positive symptoms of psychosis, depression, and stronger beliefs of negative schemas. These results reveal a similar pattern of higher frequencies of risk factors and symptoms of mental-health problems among people living in urban areas was found in a developing country. Urban living may be linked exposure to mental health risk factors and thus, increase the risk of having symptoms of mental health problems. Future research should investigate this mechanism in a longitudinal data.
AbstrakRuang Terbuka Hijau (RTH) merupakan ruang dengan vegetasi yang berfungsi sebagai penyerap gas karbondioksida (CO2) dalam bentuk karbon tersimpan sehingga dapat tercapai suatu kualitas lingkungan udara kota yang bersih dan nyaman. Penelitian ini bertujuan untuk menganalisis status dan faktor-faktor yang mempengaruhi tingkat keberlanjutan RTH publik sebagai cadangan karbon di Kota Pekanbaru. Data diperoleh melalui metode survey, pengamatan dan wawancara dianalisis menggunakan Multi Dimensional Scaling (MDS). Hasil penelitian menunjukkan bahwa pengelolaan RTH publik Kota Pekanbaru termasuk kurang berkelanjutan (49,57). Dimensi sosial (52,24) dinilai cukup berkelanjutan. Sementara dimensi ekologi (46,23), ekonomi (49,91), dan kelembagaan (49,93) tergolong kurang berkelanjutan. Secara umum disimpulkan bahwa pengelolaan RTH Kota Pekanbaru tergolong kurang berkelanjutan. Peningkatan indeks dan status keberlanjutan pengelolaan RTH Kota Pekanbaru perlu diupayakan dalam perspektif pembangunan kota berkelanjutan. AbstractGreen Open Space (GOS) is a space with vegetation that serves as an absorber of carbondioxide gas (CO2) in the form of carbon is stored so that a good quality of clean and comfortable city air environment could be achieved. This study aimed to analyze the status and the factors that affect the level of sustainability of public green space as a reserve of carbon in Pekanbaru. Data obtained through the survey, observation, and interviews method were analyzed using Multi Dimensional Scaling (MDS). The results showed that the management of public green space was less sustainable (49.57). The social dimension (52.24) is considered quite sustainable. While the dimensions of the ecological (46.23), economic (49.91), and institutional (49,93) relatively less sustainable. In general the management of Pekanbaru City GOS relatively less sustainable. Improving index and sustainability status RTH Pekanbaru City management needs to be pursued in the perspective of sustainable urban development.
The aims to determine the effect of chitosan concentration and smoking time on the quality of smoked catfish (Pangasius sp.) and produce Student Worksheet design. This research was divided into two step, there is experimental step and the Student Worksheet design. At the experimental step, used a factorial Completely Randomized Design (CRD). Factor I is the concentration of chitosan, and factor II is duration of smoking time. This study consisted of 12 treatments with 3 replications so that there were 36 experimental units. Parameters observed were protein content, fat content, water content and organoleptic on appearance, scent, taste and texture. The results showed that the effect of chitosan concentration and smoking time had an effect on treated with 3% chitosan and 3 days of smoking showed the best results, with the total protein content was 35.89%, fat content was 29.72% and water content was 15.27%. Meanwhile, the organoleptic test results of smoked catfish on the aspects of appearance, scent, taste and texture, the best treatment was also found in smoked catfish with 3% chitosan treatment and 3 days of smoking time. The results can be used as a student worksheet design on Food Additives material for class XI high school.
This study aims to determine the effect of the concentration of rice husk charcoal and cow manure on the growth of Dayak onions (Eleutherine americana Merr.) And produce Student Worksheets for class XII SMA. This research was conducted in Jayapura Village, Siak Regency, in October-December 2019. This study used an experimental method with a completely randomized factorial design consisting of 2 treatments using a combination of rice husk charcoal and cow manure and each treatment was repeated as much 3 times. The parameters of this study were leaf length, number of leaves, number of tillers, leaf wet weight, and tuber wet weight. The design of LKPD development refers to the stages of the Problem Based Learning model which are simplified into the Analyze and Design stages. The results showed that the combination of rice husk charcoal and cow manure can increase the growth of Dayak onions significantly affected at a dose of 90 gr/tan (S2K2) with the best treatment on each parameter observed. The results obtained will be used as a development material for the growth and development of Class XII SMA in KD 3.1 and 4.1. The results of the design of learning tools in the form of Syllabus, RPP and LKPD.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
