Published: July 2019

Steam Electrics Power Sijantang Sawahlunto in West Sumatra, produce fly ash waste from coal burning which is very much every day (about 300 tons/day). Air pollution caused by fly-ash has been disturbing the community surrounding due to environmental pollution, the pollution has been carried away by water flown to the rice fields, causing the rice crops of community are damage. It is already a big problem, because the public has repeatedly protested to the PLN, even the local government had been repeatedly requested to the PLN, to resolved that the issue soon. To solved that problem, PLN in cooperation with Padang State of Polytechnic, has done some research in order to utilize the waste fly ash into building materials. The results of this study prove that the waste fly ash can be used as the basic material to produce instant tiling mortar. Through research conducted, it is found a smart way out, where "there is a problem that can be used as an opportunity" especially if people are trained and given the opportunity to produce mortar instant in their homes (home industry), it will be able to improve the economy and welfare of the people around the plant Sijantang.

One of the diseases that can be detected through blood tests is Dengue Hemorrhagic Fever (DHF). The number of platelets are one of the guidelines used by doctors diagnosing DHF. Actually, platelets can be calculated manually, but it will be very difficult if the platelets are counted quite a lot. So, we need a technology that can calculate the number of platelets quickly and automatized to get more accurate results. The automatic systems built by using the template matching method with image processing include HSL Segmentation with Luminance type and Reverse Color Manipulation. After building the system, the system will automatically look for objects that match the template in the sample image and then give the marking and calculate it.The overall system testing results are the number of platelets which are then classified manually at what degree of DHF.

Traffic is an important part of road pavement design in addition to subgrade strength. This is because traffic is a burden for the road and is very decisive in the thick planning of each layer of pavement. Thus the calculation of the traffic load should have been carried out before carrying out the design of the pavement. The Sicincin - Lubuk Alung ring road section located in Kab.Padang Pariaman is one of the road sections designed with pavement design. Therefore, a traffic survey was carried out on the road section.
Traffic surveys are carried out for three days, two days on weekdays and one day on holidays. Every day the survey time is divided into three times, morning, afternoon and evening at rush hour. The survey in the morning takes place at 07:15 - 08:15 and 08:15 - 09:15 while in the afternoon it takes place at 13:00 - 14:00 and 14:00 - 15:00. Furthermore, for the afternoon survey, it will be held at 16:00 - 17:00 and 17:00 - 18:00. After processing the data, in each survey period the LHR value is obtained for both directions. The LHR value used for pavement design is the largest LHR value of all LHR values obtained.

Batang Kuranji merupakan sungai yang memunyai luas DAS sebesar 187,50 km2. Banjir yang terjadi akibat luapan Batang Kuranji apabila itensitas hujan tinggi membuat kerugian bagi masyarakat disekitar aliran sungai. Pengendalian banjir direncanakan bertujuan untuk menaggulangi banjir sepanjang aliran batang kuranji. Dalam perhitungan Debit Banjir tahunan menggunakan metoda Melchior didapat Q10 adalah 730, 48 m3/dtk. Analisa banjir dilanjutkan menggunakan Program HEC-RAS 4.0 untuk mengetahui tinggi banjir dari luapan batang kuranji. Hasil analisa menggunakan HEC-RAS terhadap 9 buah cross memberikan gambaran hampir semua titik mengalami kondisi banjir (luapan), dan hanya beberapa titik saja yang tidak mengalami luapan. Hal ini disebabkan karena kontur daerah bagian hulu rendah. Hasil menggunakan HEC-RAS 4.0 didapat tinggi banjir setinggi 0,20 meter pada bagian hilir dan setinggi 1,40 meter pada bagian hulu. Perencanaan tanggul menjadi solusi sebagai penahan luapan air Batang Kuranji dengan dimensi tinggi 2,40 meter, lebar atas 1,00 meter dan lebar bawah 1,5 meter dengan kontrol stabilitas aman terhadap guling dan memenuhi safety factor.

Background: It is increasingly recognized that the complex functions of human cognition are not accurately represented by arbitrarily-defined anatomical brain regions. Given the considerable functional specialization within such regions, more fine-grained studies of brain structure could capture such localized associations. However, such analyses/studies in a large community-dwelling population are lacking. Objective: To perform a fine-mapping of cognitive ability to cortical and subcortical grey matter on magnetic resonance imaging (MRI). Methods: In 3,813 stroke-free and non-demented persons from the Rotterdam Study (mean age 69.1 (±8.8) years; 55.8% women) with cognitive assessments and brain MRI, we performed voxel-based morphometry and subcortical shape analysis on global cognition and separate tests that tapped into memory, information processing speed, fine motor speed, and executive function domains. Results: We found that the different cognitive tests significantly associated with grey matter density in differential but also overlapping brain regions, primarily in the left hemisphere. Clusters of significantly associated voxels with global cognition were located within multiple anatomic regions: left amygdala, hippocampus, parietal lobule, superior temporal gyrus, insula and posterior temporal lobe. Subcortical shape analysis revealed associations primarily within the head and tail of the caudate nucleus, putamen, ventral part of the thalamus, and nucleus accumbens, more equally distributed among the left and right hemisphere. Within the caudate nucleus both positive (head) as well as negative (tail) associations were observed with global cognition. Conclusions: In a large population-based sample, we mapped cognitive performance to cortical and subcortical grey matter density using a hypothesis-free approach with high-dimensional neuroimaging. Leveraging the power of our large sample size, we confirmed well-known associations as well as identified novel brain regions related to cognition.

Published: July 2019

Background: Although physical activity has been associated with better cognitive function and reduced dementia risk, its association with cognitive decline in normal aging remains uncertain. Objective: To determine whether physical activity in youth and older age are associated with age-related cognitive change. Methods: Over a period of 27 years, 2,027 community-dwelling adults (mean age 73.5; 60% women) of the Rancho Bernardo Study of Healthy Aging completed up to seven cognitive assessments, including tests of global cognitive function, executive function, verbal fluency, and episodic memory. At each visit, participants reported concurrent physical activity. At baseline (1988– 1992), participants additionally reported physical activity as a teenager and at age 30. For each age period, participants were classified as regularly active (3+ times/week) or inactive. Results: Associations between concurrent physical activity and better cognitive function were stronger with advancing age on all tests, even after accounting for education, health, and lifestyle factors, as well as survival differences ( ps < 0.05). Baseline physical activity did not predict rates of cognitive decline ( ps > 0.40). Individuals who were physically active at age 30 and older age maintained the highest global cognitive function with advancing age ( p = 0.002). Conclusion: Regular physical activity is associated with better cognitive function with advancing age. Physical activity in young adulthood may contribute to cognitive reserve, which together with physical activity in later years, may act to preserve cognitive function with age.

Published: July 2019

Background: The UCP2 gene variation has been associated with the increased risk for obesity and lower response to an energy-restricted diet. Objectives: This study aimed to compare the effect of intermittent fasting diet (IFD) and low-calorie diet with exercise (LCD-ex) based on UCP2 gene variations. Methods: Subjects were adult men and women ( n = 125) with body mass index between 25–40 kg/m2. During IFD, subjects were abstained from eating and drinking for 13 hours. During LCD-ex, subjects received dietary counseling for low-calorie diet and group exercise program. Anthropometric changes were compared after 4 weeks. The -866 G/A (rs659366) UCP2 gene variation was analyzed and subjects were separated into 2 groups: GG and AA+GA. Results: In GG genotype, IFD was associated with a higher weight reduction compared to LCD-ex (–1.7±0.2 vs. –0.7±0.3 kg, p = 0.016). In AA+GA genotypes, there were no differences in weight loss between IFD and LCD-ex (–1.7±0.3 vs. –1.7±0.3 kg, p = 0.967). No differences in energy intake between genotypes (all p > 0.05). Conclusions: This study shows that GG genotype of -866 G/A UCP2 was associated with a better response towards IFD compared to LCD-ex.

Seiring dengan pesatnya kemajuan teknologi saat ini, kebutuhan manusia menjadi lebih beragam, termasuk kebutuhan akan informasi. Tidak hanya media informasinya yang semakin beragam, jenis informasi yang dibutuhkan juga semakin beragam, salah satunya adalah kebutuhan informasi akan posisi kita terhadap lingkungan sekitar. Untuk memenuhi kebutuhan itu sebuah sistem pemosisi diciptakan.
Sistem pemosisi yang banyak digunakan saat ini cenderung berfokus pada lingkup ruang yang besar (global) padahal, dalam lingkup ruang yang lebih kecil (lokal) sebuah sistem pemosisi juga diperlukan, seperti di ruang-ruang terbuka umum (taman atau kebun), ataupun dalam sebuah bangunan. Sistem pemosisi lokal yang ada saat ini sering kali membutuhkan infrastruktur yang mahal dalam pembangunannya.
Aplikasi Pemosisi Lokal Berbasis Android dengan Menggunakan GPS ini adalah sebuah aplikasi yang dibangun untuk memenuhi kebutuhan pengguna akan informasi lokasi dan posisi mereka terhadap lingkungan di sekitarnya dalam lingkup ruang yang lebih kecil (lokal) dengan memanfaatkan perangkat GPS (Global Positioning System) yang telah tertanam dalam perangkat smartphone Android agar infrastruktur yang dibutuhkan lebih efisien.
Dalam implementasinya, Aplikasi Pemosisi Lokal ini bertindak sebagai klien dengan dukungan sebuah Database Server yang berfungsi sebagai media penyimpanan data serta sumber referensi informasi yang dapat diakses melalui jaringan internet sehingga tercipta sebuah sistem yang terintegrasi secara global.
