Published: July 2019

Abstract

Sie reuboh is an Acehnese traditional cuisine which uses red-meat as the main protein and is prepared specifically with addition of beef tallow, traditional vinegar and blend of spices. The dish was extremely popular, has a long shelf life, exquisite and complex taste. However due to the changing in life styles and modernization, nowadays the dish hardly prepared at home and has varied of recipes. Based on previous studies, the updated recipe was formulated by varying the amount of beef tallow and vinegar as independent variables. Furthermore, this study aims to assess the physical quality (pH and cooking weight loss) and sensory attributes (color, aroma, flavor, texture). The sensory attributes were divided onto ten specific attributes, which were assessed with Qualitative Descriptive Analysis (QDA) method. The analysis of variance (ANOVA) showed that addition of beef tallow significantly affected (P≤0.01) the umami flavor of sie reuboh, whereas addition of vinegar significantly (P≤0.01) affected pH, cooking weight loss, color, meat flavor, sour flavor, tenderness and chewiness of produced sie reuboh descriptively. The sensory profiles of each treatment were also described, where the increasing amount of vinegar tend to decrease pH, prevent cooking weight loss and elevate color, tenderness and sour flavor of the product.1

Abstract

Kopi luwak (civet coffee) is produced exclusively from coffee beans excreted by Indonesian palm civet or luwak (Paradoxurus hermaphroditus) and relatively has a high price. The aim of this research was to identify amino acid compositions of kopi luwak (green and roasted beans), its changing forms and its correlation to sensory profile. The coffee beans of kopi luwak were collected from six locations in Gayo Highland, Aceh-Indonesia. Amino acid compositions were analyzed by LC-MS and sensory profiles were performed using a cupping test based on Specialty Coffee Association of America (SCAA) procedures. The result showed that green and roasted beans had significant differences on their Alanine, Tyrosine, Cysteine and Arginine contents. Valine, Glutamine, Aspartic acid and Glutamic acid are considered as the main amino acids which have higher percentage in both green and roasted bean. Several amino acids are absence in green bean but presence in roasted bean or vice versa, such as alanine and arginine. Glutamic acid content was the highest among others, both in green bean and roasted bean. The sensory profile of civet coffee showed that all samples from various origins/sources were classified as specialty coffee because the obtained total score of cupping was above 80.

Abstract
Database course is the main courses in the department of informatics and computer science. This course aims to provide knowledge to students to build and manage data on Database Management Systems (DBMS) like MySQL. Therefore, the implementation of database processing practices in one of the DBMS such as MySQL is very important as basic skills in the field of informatics. With the growing number of informatics students, lectures cannot correct the results of student exercises quickly. For that, we need a system that can help lecturers to make corrections of query exercise on MySQL automatically, which is called Online Judge MySQL. This application was developed using NodeJS to execute queries that users input and ReactJS to build its interfaces. Testing is done by using this application for the online exam in several classes simultaneously. The results show that this application can correct the test results quickly and lightly.
Co-residence as housing strategy for Betawi families: Case study of Betawi family houses in Cengkareng, West Jakarta
Authors: Arima D H , Adianto J , Gabe R T 
Published: July 2019

Abstract
The number of Betawi families, known as the native tribe of Jakarta, in the capital city is decreasing due to massive urbanization. The fierce economic competition with the resilient migrants has purged them to the suburban Jakarta. In order to live in Jakarta and close to their current job locations, transforming the inherited multi-generational family house to co-residence becomes the favorable option. This paper aims to examine the co-residence as a housing strategy of Betawi families to live in Jakarta. There are certain adjustments in determining the strategy of living together, especially with a lot of relatives. Qualitative research method with in-depth interviews and longitudinal through direct observations were delivered to investigate and discover the meticulous the process of transformations throughout the years. These Betawi families have been living the residences since the 1980s, and both have numerous core family from various generation. This type of living, co-residence, need some strategies such as expanding new spaces, shared spaces and merger-separation of the clean-dirty water and electric channel. Based on the selected two houses of Betawi families in Cengkareng, West Jakarta, this paper poses the argument that co-residence is not only the housing strategy for Betawi families to live in Jakarta but also generating extra incomes to the family as it provides rent rooms for migrants.
Active waiting: Potentials of waiting area at airport
Authors: Pasaribu M T T , Arvanda E , Kusuma N R 
Published: July 2019

Abstract
For travellers in the airport, waiting is often associated as an unpleasant activity. One of the reasons of the perception is because waiting area is viewed as a space for uncomfortable waiting experience. Bissel explains that the experience of waiting is often conceptualised as a stasis period that bore the passenger to be passive. Regarding to this understanding, Schweizer and Gasparini try to dissect the potential of a waiting space by using active waiting concept as a lens of analysing the space. According to their concept, active waiting is where waiting is seen as an activity that has balance focus between achieving what is expected and how to have comfort when experiencing the process itself. This paper argues, by incorporating this concept to a waiting space, passengers will experience in both passenger system and a new occasional experience. This paper will observe and analyse the relation between spatial elements and the behaviour of passengers at a waiting area within an airport terminal, through the lens of active waiting concept. The experience of waiting can be achieved through three stages of habitation, which is lingering, tarrying, and the state of dwelling. The expected result from this study is to discover the potentials of waiting area at an airport. Findings from this paper may be useful for planning the airport waiting in order to create a more comfortable experience for the body and state of mind of the passengers.

Authors: Ambarita H 
Published: July 2019

Abstract
This work studied experimentally the performance and exhaust gas emission of a diesel engine coupled with a catalytic converter run on dual-fuel mode using refined biogas resulted from agricultural waste. The content of methane on the biogas is 70%. The experiments were carried out at constant load 1500 kW. The engine rotation varies from 1000 rpm to 1500 rpm. The biogas flow rate varies from 0 to 6 L/min. The output power of the engine operated on dual-fuel mode is better than the engine operated with pure diesel. The brake thermal efficiency of the diesel engine with flow rate of 2 L/min and 4 L/min is better than diesel only. The specific fuel consumption of the diesel engine operated on dual-fuel mode is higher than pure diesel mode. The opacity number of the engine operated on dual-fuel mode is better than pure diesel mode. However, the CO number and HC number of the engine operated on dual-fuel mode are higher than pure diesel mode. The diesel replacement ratio is within the range 15.6% % to 74.8%. It is recommended to run the present diesel engine in dual fuel mode with biogas flow rate 2 L/min - 4 L/min.

Abstract
Steel construction is mostly connected by using a welding technique. The result of the welding process can cause the change of mechanical properties of the welding zone. Therefore, it needs to be reviewed to guarantee the quality of the welding zone. This research aims to assess the effect of welding on the change of microstructure and the mechanic characteristic of welded connection. Low carbon steel was welded by using Shield Metal Arc Welding method (SMAW) with electrode E7016, diameter 2,6 mm. Type of notch used was single V with angle 70° and welding position was 1G. Then, the Charpy impact test, Rockwell hardness and micro-macro structure monitoring on the welding zone including base metal, Heat Affected Zone (HAZ) and weld metal, are conducted. The results show that the highest impact toughness value at metal welding area is 251 joule/mm2, and lowest impact toughness is at the heat affected area (HAZ) is 119 joule/mm2. Hardness values of welding zones are found of about 87,6 HRB for weld metal, 73,9 HRB for HAZ zone and 67,1 HRB for the base metal. The microstructure of weld metal zone, HAZ and base metal are included on ferrite and pearlite formed by welding on low carbon steel AISI 1010 observer by using an optic microscope.

Published: July 2019

Abstract
This study investigates the grain size characteristics and sediment types of the Aceh’s coastal deposits that are primarily based on the sieve analysis. This study is mainly driven by two reasons. Firstly, this study is a preliminary effort to identify coastal sediment in the Aceh coastal areas. Secondly, this information is important to interpret the support mechanism of sediment during transportation and depositional processes. In this study, many sediment deposits from both the east and west coasts of Aceh were collected. Laboratory sieve analysis was carried out to these samples. Then, further analysis of this sieve analysis results is carried out. The analysis reveals the past transport mechanism of this study sand deposits which is river’s channel. However, such finding should be investigated further as all the tested sand were taken at the top surface and big main rivers are not indicated at both sand locations.

Abstract

Background
Previous research documents an association between adverse childhood experiences (ACEs) and immune system inflammation. High chronic inflammation is believed to be one biological pathway through which childhood adversity may affect health into adulthood. The Blackfeet tribal community has high rates of childhood trauma and community members are disproportionately affected by inflammatory diseases.

Purpose
To investigate whether belonging to the tribal community may moderate the relationship between childhood trauma and immune system inflammation in the Blackfeet tribal community.

Methods
In a sample of 90 adults residing on the Blackfeet reservation, we measured ACEs belonging to the tribal community and two markers of immune system inflammation, interleukin-6 (IL-6) and C-reactive protein (CRP).

Results
We found that independent of age, gender, annual income, body mass index, and depressive symptoms, belonging to the tribal community and ACEs interacted to predict levels of both IL-6 and CRP (B= −.37, t[81] = −3.82, p &lt; .001, R2 change = .07 and B = −.29, t[81] = −2.75, p = .01, R2 change = .08, respectively). The association between ACEs and markers of immune system inflammation was statistically significant for community members who reported low levels of belonging to the community.

Conclusions
The findings of this study have important implications for intervention research seeking to reduce risk for inflammatory diseases for at-risk populations. Fostering stronger connections to the larger tribal community may positively affect risk for inflammatory diseases. Future work should examine the behavioral and psychosocial pathways through which stronger connections to community may confer health benefits.
Who Files for Bankruptcy? The Heterogeneous Impact of State Laws on a Household’s Bankruptcy Decision
Authors: Miller Michelle M 
Published: July 2019

Abstract
This article examines the heterogeneous impact of state exemption laws and state garnishment laws on bankruptcy. Using a new household-level dataset, my empirical specification simultaneously examines the impact these laws have on a household’s bankruptcy decision as well as a household’s assets and unsecured debts. I find that high exemption laws have a positive impact on bankruptcy and that this effect is increasing in assets. Additionally, I find that high garnishment rates have a positive impact on bankruptcy, which is increasing in income. Moreover, I examine the policy implications of standardizing state exemption laws and state garnishments laws. Understanding the heterogeneous effects of these laws is crucial as they suggest that a household with a given set of financial characteristics will seek bankruptcy relief if it resides in one state but will have to use alternative consumption smoothing measures if it lives in a different state.
Neuroimaging in Parkinson’s disease dementia: connecting the dots
Authors: Weil Rimona S , Hsu Joey K , Darby Ryan R , Soussand Louis , Fox Michael D 
Published: July 2019

Abstract
Dementia is a common and devastating symptom of Parkinson’s disease but the anatomical substrate remains unclear. Some evidence points towards hippocampal involvement but neuroimaging abnormalities have been reported throughout the brain and are largely inconsistent across studies. Here, we test whether these disparate neuroimaging findings for Parkinson’s disease dementia localize to a common brain network. We used a literature search to identify studies reporting neuroimaging correlates of Parkinson’s dementia (11 studies, 385 patients). We restricted our search to studies of brain atrophy and hypometabolism that compared Parkinson’s patients with dementia to those without cognitive involvement. We used a standard coordinate-based activation likelihood estimation meta-analysis to assess for consistency in the neuroimaging findings. We then used a new approach, coordinate-based network mapping, to test whether neuroimaging findings localized to a common brain network. This approach uses resting-state functional connectivity from a large cohort of normative subjects (n = 1000) to identify the network of regions connected to a reported neuroimaging coordinate. Activation likelihood estimation meta-analysis failed to identify any brain regions consistently associated with Parkinson’s dementia, showing major heterogeneity across studies. In contrast, coordinate-based network mapping found that these heterogeneous neuroimaging findings localized to a specific brain network centred on the hippocampus. Next, we tested whether this network showed symptom specificity and stage specificity by performing two further analyses. We tested symptom specificity by examining studies of Parkinson’s hallucinations (9 studies, 402 patients) that are frequently co-morbid with Parkinson’s dementia. We tested for stage specificity by using studies of mild cognitive impairment in Parkinson’s disease (15 studies, 844 patients). Coordinate-based network mapping revealed that correlates of visual hallucinations fell within a network centred on bilateral lateral geniculate nucleus and correlates of mild cognitive impairment in Parkinson’s disease fell within a network centred on posterior default mode network. In both cases, the identified networks were distinct from the hippocampal network of Parkinson’s dementia. Our results link heterogeneous neuroimaging findings in Parkinson’s dementia to a common network centred on the hippocampus. This finding was symptom and stage-specific, with implications for understanding Parkinson’s dementia and heterogeneity of neuroimaging findings in general.

Abstract

Background and Aims
Based on genetics and natural history, Crohn’s disease can be separated into two entities, an ileal and a colonic disease. Protein-based approaches are needed to elucidate whether such subphenotypes are related to distinct pathophysiological processes.

Methods
The proteome of ulcer edges was compared with that of paired control tissue samples [n = 32 biopsies] by differential proteomics in the ileum and the colon of Crohn’s disease patients [n = 16]. The results were analysed using a hypothesis-driven approach [based on the literature] and a hypothesis-free approach [pathway enrichment analyses] to determine common and segment-specific pathophysiological processes associated with ileal and colonic CD ulcer edges. To confirm the involvement of a key pathway highlighted by proteomics, two proteins were also studied by immunochemistry.

Results
In the ileum and the colon, 4428 and 5204 proteins, respectively, were identified and quantified. Ileal and colonic ulcer edges differed in having a distinct distribution of proteins associated with epithelial–mesenchymal transition, neutrophil degranulation, and ribosomes. Ileal and colonic ulcer edges were similarly characterized by an increase in the proteins implicated in the endoplasmic reticulum protein-processing pathway and a decrease in mitochondrial proteins. Immunochemistry confirmed the presence of endoplasmic reticulum stress in the mucosa of ileal and colonic ulcer edges.

Conclusion
This study provides protein-based evidence for partially distinct pathophysiological processes being associated with ileal and colonic ulcer edges in Crohn’s disease patients. This could constitute a first step toward the development of gut segment–specific diagnostic markers and therapeutics.
Effect of tree species mixing on stand structural complexity
Authors: Juchheim Julia , Ehbrecht Martin , Schall Peter , Ammer Christian , Seidel Dominik 
Published: July 2019

AbstractThe proportion of mixed-species forests is presently increasing since they are commonly seen as providing a higher level of many ecosystem goods and services than monospecific stands. This may be due to a more complex three-dimensional distribution pattern of plant elements, which has often been noted, but to date rarely been quantified. In the present study, we used terrestrial laser scanning data to analyze the relationship between tree species mixing and stand structural complexity in three regions of Germany. We examined 60 forest plots representing commercially important and typical species combinations for Central Europe. The results showed an increasing but saturating relationship between stand structural complexity and tree species diversity. Moreover, we found that as the proportion of broadleaved trees increased, the stand structural complexity of coniferous stands also increased. Our study provides evidence that the conversion of monospecific conifer stands into mixed forests with broadleaved tree species as well as mixing tree species with interspecific differences in physiological and morphological traits can promote the development of structurally more complex stand structures.
Increased Individual Tree Growth Maintains Stand Volume Growth after B-Level Thinning and Crop-Tree Management in Mature Oak Stands
Authors: Ward Jeffrey S , Wikle Jessica 
Published: July 2019

AbstractSix study areas were established in 80–125-year-old upland oak stands on average sites to compare stand and individual tree growth response following two active treatments (B-level thinning, crop tree) with an unmanaged control. Initial stocking of 104 percent was reduced to 62 percent and 60 percent on the B-level and crop-tree-management plots, respectively. Approximately 7,200 board feet per acre (International ¼) were harvested on the actively managed plots with upland oaks accounting for 81 percent of pre- and 86 percent of residual stand. Eleven-year diameter and volume growth of oak sawtimber trees was greater on actively managed plots. Growth response increased with degree of release and was maintained for the length of the study. Because of the increased individual tree growth of oaks in response to release, stand volume growth of oak sawtimber did not differ between treatments. In contrast to an 11-year decline of poletimber stocking on unmanaged plots, poletimber stocking increased on managed plots as diameter growth increased in response to partial release. This may increase difficulty of regenerating oak in the future. For those mature red oak stands where traditional regeneration prescriptions will not be implemented or will be delayed, commercial harvests can be conducted without compromising stand volume growth of oak.
The milk-based diet of infancy and the gut microbiome
Authors: Hao Hu , Zhu Lixin , Faden Howard S 
Published: July 2019

AbstractThe composition and the diversity of the gut microbiome play a major role in the health and well-being of humans beginning at birth. The impact of the diet on the structure and the function of the gut microbiome is evident by the changes in the gut microbiome concurrent with the transition from human milk to solid food. Complex oligosaccharides contained in milk are essential nutrients for commensal microbes in the infant gut. The most important commensal bacterium in the infant gut, bifidobacterium, requires α1, 2 fucosylated oligosaccharides for growth. Because not all humans are able to secrete α1, 2 fucosylated oligosaccharides into milk, the gut microbiome of infants and bifidobacteria, in particular, vary considerably between ‘secretors’ and ‘non-secretors’. A paucity of α1, 2 fucosylated oligosaccharides and bifidobacteria in the gut of infants may be associated with poor health.
