A Comparison of Antioxidant Properties of Two Apple Cultivars
Authors: Šahinović Emir , Murtić Senad
Published: December 2019

The apple (Malus domestica Borkh.) possesses a number of health-promoting properties. The main beneficial effects of apple fruits on human health are associated with the antioxidant properties of components synthesising in apple fruits during their growth and development. Phenolic compounds and flavonoids are such components that contribute significantly to the antioxidant capacity of fruits, thus enhancing their health properties. The purpose of this study is to compare the antioxidant properties (namely antioxidant capacity, ascorbic acid, total phenolic and flavonoid contents) of the ‘Idared’ and ‘Braeburn’ apple cultivars, grown under optimal growing conditions in the Goražde area. Ascorbic acid contents were estimated using the 2.6-dichlorophenolindophenol titration method, whereas total phenolics were determined using the Folin-Ciocalteu method. Furthermore, total flavonoids were determined using the aluminium chloride colorimetric assay, whereas the ferric reducing/antioxidant power assay was used to determine the total antioxidant capacity of the apple fruits examined. The average values of the ascorbic acid, the total phenolic and flavonoids contents, and the total antioxidant capacity of the ‘Idared’ apples under consideration were 8.09 mg 100 g−1, 34.56 mg gallic acid equivalents 100 g−1, 12.62 mg catechin equivalents 100 g−1 and 323.28 μmol Fe2+ 100 g−1of fresh weight, respectively. The average values of the total phenolic and flavonoids contents, as well as the antioxidant capacity of the ‘Braeburn’ apples examined were as follows: 8.89 mg 100 g−1, 33.4 mg gallic acid equivalents 100 g−1, 13.56 mg catechin equivalents 100 g−1 and 367.01 μmol Fe2+ 100 g−1 of fresh weight, respectively. The analyses performed indicate that the differences recorded in the parameter values between the apple cultivars ‘Idared’ and ‘Braeburn’ were statistically non-significant. A correlation data analysis confirmed that phenolic compounds are the carriers of the antioxidant activity of apples.
Hugolín Gavlovič on moral education: Enlightenment ideas in baroque literature?
Authors: Komenská Katarína
Published: December 2019

The work of Hugolín Gavlovič belongs is part of the most influential literary and didactic heritage of 18th century literature in the region of contemporary Slovakia. Even though Gavlovič was not a systematic moral philosopher, the role and importance of ethics in his literary work is significant. He contributed greatly to the debate on moral education, which was (in the context of that time) linked to the fulfilment of God's will and to the accomplishment of a good life. In his extensive poetic work Valaská škola mravúv stodola [Shepherd´s school of morals], the author not only formulated moral norms but, inspired by classical Greek philosophy, he also defined them in the wider ethical context of virtue, morals, and human nature. In this study, the historical context of his work, marked by the literary and cultural transition to the Enlightenment era, will be presented, concepts related to the understanding of good life (as a goal of moral education) will be identified, and the possibility for further philosophical and ethical analysis of Gavlovič’s work will be offered (through a reflexion of Aristotle’s thoughts referred to in Valaská škola). Overall, the paper offers an original point of view on how to interpret the thoughts of Hugolín Gavlovič from the perspective of ethics. This has been, despite the impact of his work, rather omitted.
Teachers’s attachments to their place of work and their working locality. A case study of geography teachers in the Silesian Voivodeship (Poland)
Authors: Dacy-Ignatiuk Katarzyna , Hibszer Adam
Published: December 2019

The authors of the article sought to answer the questions: do geography teachers feel a tie with their place of work, what is the strength of this relationship and what factors influence these declared ties with the place. A step towards knowing the answers is the declared subjective assessment of emotional relationships with such a place. To this end, surveys were conducted among geography teachers. Due to their profession, they are a social group having a wide range of influence on young people and their attitudes towards their local geographical environment. Organizational reasons (the ability to reach teachers of all schools through the information exchange platform between Board of Education and school heads – so-called the headmasters panel) decided to examine a selected group of respondents – geography teachers of the Silesian Voivodeship. Google questionnaire was used as an electronic form of data collection. The research was quantitative and only partly qualitative. The analysis of the obtained results gave an interesting view of the perception of teachers' relations with the place where their school is located – their place of work. Almost all respondents declared the existence of a territorial bond with their place of work. The workplace itself is an important factor in the formation and strength of these ties. The length of residence in a given place was also important, and its type (town or a village) and size were less important. For half of the surveyed teachers, it was difficult for them to indicate the distinguishing feature (symbol) of their place of work, regardless of whether they were inhabitants or commuters from elsewhere.

Authors: Aleksanyants Gaik Derenkovich , Pogodin Andrey Vladimirovich , Epishkin Igor Vladimirovich
Published: December 2019

In a series of studies on the adaptation processes of the main body systems of highly skilled male and female athletes in the range of 16-46 years old using immunological biochemical, hematological, eographical, spirometric, gasometric, anthropometric and ergometric methods and load testing established the physiological patterns of formation of involutive-age-related changes in the functional state of athletes of the second adult age. In the age range of 37-46 years old relative to the range of 16-36 years old: changes in the morphometric parameters of the physical status are determined, causing a decrease in the integrated bioenergy indicators; the intensive formation of metabolic factors of fatigue was established at a low-intensity threshold mode of work – aerobic-anaerobic; high intensity of non-specific adaptation processes is shown; revealed features of urgent responses of the main adaptation systems (hormone-metabolic, autonomic nervous, cardiovascular, respiratory) at the level of threshold operation modes. Highly qualified female athletes of 37-45 years old have an anovulatory character of the menstrual cycle, during which chronobiological mechanisms of adaptation processes are studied and systematized, consisting in the features of regulatory nervous effects on heart rate, hemodynamic and ventilatory functions. The revealed changes in adaptation processes in athletes of the second adult age can be used as the basis of the analytical base for predicting the functionality of elite and professional athletes of late periods of ontogenesis.
Formation and education of the elderly in Russia
Authors: Mamayusupova Kristina
Published: December 2019

The social attention of today's world, in continuous transformation, is focused above all on the education and education of the elderly. Taking into account the fact that the lifestyles of elders around the world are tuned to European ones, this article aims to shed light on the life of the elderly in Russia, their education and education. Nowadays, having an active lifestyle means - for the elderly - to be strengthened by sport, by the possession of digital skills, by socializing with relatives, friends and peer groups, as well as by travel and work. Creating oneself through curious thought towards all that is information about the world increases one's knowledge and contributes to the maintenance of physical and mental form. The awareness of living life by forming and educating oneself dynamically favours, in the elderly, a constant search for the self and a desire to experience oneself by adhering ever more to new initiatives. Unfortunately, in Russia, there are still many older people whose existential situation could be characterized by the concept of “social closure”. This situation is due, for the most part, to the unfavourable climatic conditions, poor health and severe economic conditions. Becoming active pensioners, however, is possible, “bypassing” the obstacles aimed at the destruction of the “critical self”. It would, therefore, be necessary to begin to consider themselves as a great Russian “old heritage” so that, soon, the trained eyes of “lovers” can establish their priceless value.

Published: December 2019

Introduction: Chemical industry is obligatory to improve new chemically effective components. Spices are potential new antimicrobials.

Objective: The present study was designed to evaluate the antibacterial and antifungal activity of fifty aromatic spices and medicinal herbs obtained from Turkey.

Material and methods: In vitro antibacterial activities of a total of fifty acetone extracts from aromatic spices and medicinal herbs were studied by disc diffusion and agar diffusion method. The extracts were tested against three Gram-positive bacteria (Listeria monocytogenes, Staphylococcus aureus, Bacillus cereus), four Gram-negative bacteria (Proteus vulgaris, Escherichia coli, Pseudomonas aeruginosa, Salmonella typhimurium) and two fungi (Aspergillus niger, Candida albicans).

Results: The highest antimicrobial activity was observed in the extract of Alpinia officinarum against Salmonella typhimurium and Cassia angustifolia against Bacillus cereus. Many of the extracts showed minimum inhibition concentration at even lowest dose.

Conclusion: The obtained results showed that aromatic spices and medicinal herbs may be used as natural antimicrobials against diseases.
Are Sexual Minorities Hard-to-Survey? Insights from the 2020 Census Barriers, Attitudes, and Motivators Study (CBAMS) Survey
Authors: Bates Nancy , García Trejo Yazmín A. , Vines Monica
Published: December 2019

As a stigmatized and vulnerable population, sexual minorities are often assumed to also be a hard-to-survey population. Despite this implicit assumption, there is little empirical evidence on the topic. Using a nationally representative survey that included sexual orientation (the Census Barriers, Attitudes, and Motivators Survey), we examine level of effort, the Census Bureau’s Low Response Score (LRS), and stated intent to respond to the 2020 Census as proxy measures to explore this assumption. We found no evidence that sexual minorities required higher levels of effort to secure participation in the survey. Additionally, we found that compared to straight respondents, lesbians, gays, and bisexuals had a higher intent to respond to the 2020 Census. We surmise the current social climate in the United States may be a contributing factor to these findings.
Can They and Will They? Exploring Proxy Response of Sexual Orientation and Gender Identity in the Current Population Survey
Authors: Holzberg Jessica , Ellis Renee , Kaplan Robin , Virgile Matt , Edgar Jennifer
Published: December 2019

Within the United States Federal Statistical System, there has been interest in capturing sexual orientation (SO) and gender identity (GI), collectively known as SOGI, on surveys to allow researchers to estimate the size and distribution of sexual and gender minority populations. SOGI measurement in federal surveys may also help to identify disparities between people who identify as lesbian, gay, bisexual, and transgender (LGBT) and those who do not in domains such as health, crime, or employment. Although research has been conducted on best practices for SOGI measurement in surveys, it has largely been limited to examination of self-reports. Many federal surveys use proxy reports, when one person generally responds for all household members. This research used cognitive interviews and focus groups to explore proxy response to SOGI questions. We explored potential sources of measurement error in proxy responses to SOGI questions, including sensitivity, difficulty, as well as the willingness and ability of respondents to answer SOGI questions about other household members. We also conducted paired interviews with members of the same household to assess level of agreement for SOGI questions. Findings suggest that measuring SOGI by proxy may be feasible in federal large-scale, general population surveys.
Principal-Agent Relation and Contracting-out for Employment Case Management to Enable Third-Country Nationals’ Transition to Work
Authors: Bruno Esien Eddy
Published: December 2019

This paper analyzes the role of public and private employment-service agencies in contracting-out for employment case management under principal-agency relation to understand young third-country immigrants’ transition to work in Czechia, Poland, and Hungary. Existing research pointed to contracting-out as a major trend in public-service reforms when the government (principal) hires private employment agencies (agents) to perform service delivery, but overall the control of standards and the accountability to the public remains with the authority. Although the principal-agency relation shows human beings as rational and opportunist in corporate governance, there is still little research in CEE countries explaining the role of public and private employment agencies under principal-agency relation in contracting-out for case management to understand young third-country immigrants’ transition to work. Based on a qualitative cross-national case-oriented research approach with fewer-country comparison, documents and scholastic texts are collected and analyzed by means of a document and content analysis technique to fill in this gap. The findings show that open information, regulation, and monitoring administrative devices are a major perceived influence in principal-agency relational governance with a lack of cooperation that may impair the quality and service when looking at issues such as employment-related transition of young third-country immigrants and socio-economically disadvantaged groups in a contracting-out setting. The study demonstrated certain decentralized new public administration governance similarities but dissimilarities from the country’s institutional context. The outcome points to regulatory administrative devices to target agencies’ behavior and young vulnerable people’s need for paid work. This is relevant to performance monitoring in contemporary fluid society targeting benefits and scarce resources that may not only constrain ethnic minorities’ upward mobility, but the economy and the social cohesion process.
‘Because Migri Says So’:
Authors: Bodström Erna
Published: December 2019

This article argues that authorisation and moral evaluation are the dominant legitimation strategies used in asylum decisions by the Finnish Immigration Service (Migri). After the migration events of 2015, the percentage of accepted asylum claims dropped dramatically in Finland, causing concern about the legal rights of asylum seekers. Drawing on theoretical literature concerning asylum decisions, borders and language, this article is based on a systematic analysis of 77 asylum decisions. It aims to answer the following questions: What strategies of legitimation does Migri use to support their negative asylum decisions? How are these strategies used? The study reports that the reasons behind negative asylum decisions are often not openly provided. Instead, the decisions largely rely on authorisation and implicit moral evaluation; the decision is so ‘because Migri says so’. This lack of transparency has adverse consequences for the due process of asylum seekers, and these consequences can be life-changing.
Investigation of the level structure of 90Nb nucleus using the shell model
Authors: Yi-Heng Wu , Dong Yang , Ke-Yan Ma , Peng-Wei Luo
Published: December 2019

Shell model calculations have been carried out for 90Nb nucleus with the model space in which the valence protons occupy the f5/2, p3/2, p1/2, and g9/2 orbitals and the valence neutrons occupy the p1/2, g9/2, d5/2, and g7/2 orbitals. According to the calculated results, the negative parity is from the contribution of the proton of the f5/2, p3/2, and p1/2 orbits. The moderate spin states of 90Nb are mainly due to the excitation of protons from the f5/2 and p3/2 orbits to the p1/2 and g9/2 orbits across the Z = 38 subshell closure, and the high spin states arise from the excitation of a single neutron from the g9/2 orbit into the d5/2 orbit across the N = 50 shell closure.
Sorana Țopa – Journal Pages
Authors: Ciobotaru Anca Doina , Antochi Elena Carmen
Published: December 2019

In the spring of 2017, we had the chance of receiving several unpublished documents from actress Sorana Ţopa’s personal archive. Recovered by Mrs. Lucreția Angheluţă from a dark cellar in Bucharest and generously given to us to help our doctoral research1, the handwritten notebooks and typed pages help to shed... light both on the actress’ personality and the image of an era. Here are some of the pages from the manuscript Journal, fragments through which one can better see Sorana Ţopa’s personality, her reflexive abilities, her capacity to scan the relation human – destiny – era. With the hope that, one day, the Journal will be published in its entirety, we hence begin a project of restitutio in integrum – which we find both natural and necessary in a time when values are being overthrown and those who strive to start an artistic (or other type of) career feel the increasingly inequitable fight with the pressures of the socio-economic system. Reading these pages, one understands that freedom of spirit cannot be crushed by any political regime, on one condition: being aware of the fact that “becoming an easy prey for these masters of pulling ideological strings would be proof of downright superficiality and gross immaturity”. And maybe there is something else to be understood: any of Thalia’s servants’ chances are based equally on talent and the reading of profound pieces of writing. Beyond the pages of the Journal, there is the... telling silence of doubt. “Your eyes, becoming more accurate, clearer, could reflect the entire deposit at once; that is, you could have a clear image of the entire process and of the most intimate structure of this self. And if the eyes are not completely open, completely untouched by any intervention of the wish to see clearly and also of those obscure reactions that automatically appear from memory, then of course the state of fog persists somewhere, springing from who knows what corners of the consciousness that have not yet been cleared.”
The Language of Puppetry – Code for Remembering and Theatricalization
Authors: Bujoreanu-Huţanu Raluca
Published: December 2019

Ever since the prehistoric age, people have been endowing some objects with symbolic status and, by animating them, they have turned them into means of communicating profound truths about man and life. The need to communicate led to conceiving a system of representation through which exterior forms of expression were created and assumed, a particular way of making the invisible visible.
Medea – or the Fantasies of the Woman within Us
Authors: Botezatu Sandu Oana
Published: December 2019

From generation to generation, the theatre teacher stands in front of a new experience and that is why, each time, they have to approach the group of students by a different manner, trying to find common points, the binder that unites the team, to determine it to function flawlessly, united. Taking into account that each student comes with different life experiences, a different personality from the other actors, different visions and expectations, the teacher has the difficult task, in the first stage, to build a team, to make the students aware that everyone should “bring their contribution” on the construction of the show (or exam), to help, to listen, to be present and involved. The stage is not a personal fight, but a battle of ideas, which helps us to evolve, grow professionally and this is why the theatre performance cannot be made in a hostile, conflicting environment. This is how, precisely because of this need to unite a divided group made up of extremely talented students, but with totally different and powerful personalities, the acting teacher suggests as a study theme for the first semester ancient theatre, forcing the team to be together throughout the rehearsals and the show-examination on the stage, giving the choir’s soul and voice, to listen, to take over and to put, each of them, a brick in the construction of the main character, which, through the directorial vision, belonged to all and not to a single performer. This is how a merged, united team and a festival performance were built: Medea.
The Dilemma of the Composition Role
Authors: Aftanasiu Doru
Published: December 2019

What could we possibly mean by the expression “composition role”? To this question we will try to find an answer as comprehensive as possible. Are we talking only about those “character roles” mentioned by Stanislavsky? This reference can be considered, since all those character roles require stage composition, the way Stanislavsky described his own acting experiences. But is this the only landmark? Should we label as composition roles only the characters that demand text-triggered stage composition? Indeed, there are characters that assume, within their construction, elements that do not belong to the actor as an individual. But are these the only cases when the term applies?

The composition role is therefore not limited to only a few obvious milestones identified in the text. On a closer look, some characters may require a stage composition based on external elements, even if this problem is not apparent. Yet we must not misunderstand things and come to the conclusion that all roles, following a deep psychological analysis, become composition roles. If we agree that the construction of a character involves many elements pertaining to externalization, we must consider the cases where such suggestions originate from the director. Some directors claim scenic effects from the actors, sometimes contradicting the natural line of the character created by the author, maybe even completely modifying its construction. How reprehensible, however, is the acting effect? Has it only arisen from a desire to simulate virtuosity?

The term “effect” in composition can be accepted in the sense of the element helping to achieve the contrasts indispensable to the stage creation, about which Michael Chekhov speaks in To the Actor. He confers to it a broader acceptance.

Solutions not related to elementary normality can give the actor an unbearable sense of awkwardness, inevitably leading to effort. This effort will not go unnoticed by the spectator. And the spectator, almost always without hesitation, gives a negative verdict to such a performance.

And yet, visible manifestations that seem to be chaotic can be lived from the inside, which averts effort in interpretation and artificiality. The actor can avoid some clumsiness in emotions, clumsiness that is spoken about by Dario Fo, among others.

ANALISIS HEAT TRANSFER PADA BETON MASSA MENGGUNAKAN OPC TIPE I DALAM HUBUNGAN DENGAN CARA CURING
Authors: Setiawan Billy , Supartono F.X.
Published: December 2019

Skripsi ini membahas tentang heat transfer dan tegangan yang terjadi pada pilecap bermassa besar di Jembatan Pulau Balang, Kalimantan Timur. Pada pekerjaan konstruksi beton massa, sering kali dihadapkan dengan masalah-masalah tertentu yang biasanya diakibatkan oleh kelalaian dalam pembuatan beton massa tersebut. Salah satunya adalah timbulnya crack pada permukaan beton massa. Crack ini biasa diakibatkan oleh proses curing yang kurang tepat, ataupun pemakaian semen yang berlebih. Dimensinya yang besar juga dapat mengakibatkan bagian dalam beton sulit untuk melepaskan panas. Adanya perbedaan temperatur yang besar antara permukaan dan inti beton dapat menimbulkan tegangan yang mana dikhawatirkan akan melampaui kuat tarik beton, sehingga menimbulkan retak pada permukaan beton. Dalam penelitian ini, metode curing dan initial temperature akan menjadi variabel bebas, yang mana akan mempengaruhi temperatur yang terjadi. Menurut literatur, temperatur maksimum yang diijinkan adalah 70oC, sedangkan perbedaan temperatur harus lebih kecil dari 20oC. Dalam penelitian ini, dibuat opsi curing dengan cara isolasi dan temperatur awal yang rendah (perbedaan temperatur yang terjadi 11,7oC). Sedangkan untuk opsi tanpa isolasi sudah tidak memenuhi persyaratan (perbedaan temperatur yang terjadi 33oC) dan terjadi thermal crack pada permukaan beton. Pemasangan lapisan isolator dengan metode buka tutup dapat menjadi cara alternatif, namun berisiko terjadi thermal shock dan harus dilakukan trial and error untuk menghindari hal tersebut.

Tujuan dari penelitian ini adalah untuk menganalisis tingkat keinginan dari masyarakat terhadap dua sistem tesebut jika diterapkan di kota Jakarta. Pada dua sistem tersebut mempunyai cara kerja yang berbeda dalam mengatasi kemacetan dan pengendalian kendaraan pribadi. Electronic Road Pricing telah berhasil diterapkan di beberapa negara di dunia, salah satunya Singapura negara pertama di dunia yang menerapkan sistem Electronic Road Pricing dalam menanggulangi kemacetan. Sedangkan sistem kebijakan parkir merupakan sistem dimana untuk menggurangi kendaraan pribadi maka tarif parkir akan dinaikan dengan tinggi sesuai dengan kepadatan penggunaan kendaraan pribadi di daerah tersebut dan pada daerah padat perkantoran. Hal ini bertujuan agar pengguna kendaraan pribadi beralih menggunakan kendaraan umum untuk menggurangi kemacetan. Penelitian ini mengambil data dengan cara penyebaran kuesioner di jalan Sudirman – Thamrin dan responden yang melewati jalan tersebut, agar dapat mengetahui pilihan dari responden, setelah data sudah terkumpul di analisis agar dapat mengetahui pilihan dari responden tentang kedua sistem tersebut dengan menggunakan model analisis sensitifitas terhadap sistem ERP dan parkir yang berhubungan dengan total responden ,pendapatan responden ,dan kendaraan umum yang digunakan responden sehari - hari untuk mengetahui keinginan responden pada kedua sistem tersebut. Hasil dari penelitian ini adalah ketika strategi ERP dan parkir diterapkan dengan tarif yang tinggi maka pengguna jalan Sudirman – Thamrin akan beralih menggunakan kendaraan umum.

Untuk memperoleh data produktivitas, proses pelaksanaan suatu pekerjaan akan didata dan ditampilkan dalam bentuk diagram yang disebut Crew Balance Chart (CBC). Besaran produktivitas ini kemudian akan ditingkatkan untuk membandingkan biaya dari pekerjaan fabrikasi tulangan pada proyek Indonesia 1 dalam kondisi real dan optimal serta menghitung kerugian yang diperoleh akibat rendahnya produktivitas. Penelitian ini akan menggunakan metode observasi dengan video camera dan wawancara untuk memperoleh data-data yang dibutuhkan. Data yang diambil dengan cara merekam dan mencatat waktu produktif dan waktu tidak produktif dari pekerjaan fabrikasi tulangan. Waktu produktif dan tidak produktif ini akan diproses dan dihitung dengan matematika sederhana untuk mendapatkan waktu produktivitas tenaga kerja dan mengetahui koefisien produktivitas tenaga kerja. Berdasarkan hasil penelitian, dapat dikatakan bahwa produktivitas para pekerja yang terlibat kurang baik. Hal ini terbukti dari rendahnya waktu produktif para pekerja selama bekerja di lapangan, di mana waktu produktif dari para pekerja berkisar di angka 50%. Hal ini berimbas pada timbulnya pemborosan biaya pekerjaan fabrikasi tulangan. Pekerjaan yang seharusnya hanya memakan biaya sebesar Rp 287.799.030,30, justru mengeluarkan biaya sebesar Rp 301.564.489,40. Akibatnya, timbul kerugian akibat kelebihan biaya pekerjaan fabrikasi tulangan ini, yaitu sebesar Rp 13.765.459,14.

Struktur penahan gaya gempa secara umum memakai konsep Force Based Design. Konsep dari Force Based Design hanya berdasarkan kondisi elastis struktur dan tidak sesuai dengan kondisi sebenarnya dimana struktur gedung mengalami kondisi inelastis ketika mengalami peristiwa gempa. Sehingga perlu dilakukan analisis evaluasi kinerja struktur untuk mengetahui kinerja gedung ketika mencapai kondisi inelastis yang merupakan konsep Performance Based Design. Dalam penilitian ini terdapat dua metode yang dipakai untuk analisis gedung ketika mengalami kondisi inelastis, yaitu metode Direct Displacement Based Design dan metode analisis Pushover. Tujuan dalam penelitian ini untuk mengidentifikasi dan membandingkan kinerja struktur bangunan antara metode-metode tersebut. Penelitian digunakan program ETABS untuk mengetahui berapa besar gaya dan perpindahan yang dapat ditahan oleh struktur. Melalui program ETABS dapat diketahui pula level kinerja struktur bangunan tersebut. Tipe struktur bangunan yang dimodelkan berupa bangunan dengan sistem ganda. Bangunan terbuat dari beton bertulang, jarak bentang arah memanjang 53.7 m, jarak bentang arah memendek 36.2 m, dengan ketinggian 64.5 m, tinggi tiap lantai 4.3 m. Penelitian mengacu pada SNI 1726:2012, ATC-40, FEMA 356, dan FEMA 440.

Salah satu permasalahan yang timbul pada pelaksanaan konstruksi gedung bertingkat adalah terjadinya pembengkakan biaya. Biaya peralatan merupakan komponen biaya yang sering luput dari pengendalian, sehingga ada kecenderungan meningkat akibat lemahnya pengendalian. Usaha awal yang dapat dilakukan untuk meminimalisasi terjadinya pembengkakan biaya peralatan adalah dengan mengidentifikasi faktor-faktor internal penyebab terjadinya pembengkakan biaya peralatan. Faktor internal pembengkakan biaya peralatan dibagi kedalam 6 kelompok faktor, yaitu kelompok perencanaan dan pengendalian, kelompok pengorganisasian, kelompok pengadaan, kelompok operasional, kelompok pemeliharaan, dan kelompok pengawasan dan pengendalian. Studi ini dilakukan dengan menyebarkan kuesioner kepada para praktisi lapangan proyek konstruksi gedung bertingkat, seperti project manager, site manager, quantity of surveyor, quality of control, engineer, dll. Sebanyak 70 kuesioner yang telah disebarkan, jumlah kuesioner yang terkumpul kembali sebanyak 51 kuesioner. Analisis data menggunakan metode statistik deskriptif, hasil yang didapat bahwa faktor pengorganisasian merupakan sumber utama pada pembengkakan biaya peralatan pada proyek konstruksi gedung bertingkat.
ANALISIS PERILAKU TANAH DISPERSIF TERHADAP DINDING PENAHAN TANAH DALAM PEKERJAAN DEWATERING KONSTRUKSI BASEMENT

Skripsi ini menganalisis tentang metode pelaksanaan dalam pembuatan basement 3 lantai menggunakan sistem dewatering dengan dinding penahan tanah pada tanah dispersif. Tanah dispersif adalah tanah yang mudah tererosi dan terurai apabila berinteraksi dengan air, sehingga dapat menyebabkan banyak kerusakan. Perilaku tanah dispersif terhadap dinding penahan tanah juga sangat berpengaruh pada pekerjaan konstruksi dan dapat mempengaruhi kriteria desain suatu struktur. Tujuan dari analisis ini adalah untuk memberi peringatan pentingnya memahami perilaku tanah di lokasi konstruksi, terutama untuk tanah sensitif yang sangat memerlukan keberhati-hatian desain dan juga desain yang bersifat koservatifKemudian, analisis dilanjutkan dengan pengecekan kestabilan dinding penahan tanah dengan menggunakan bantuan program. Dalam simulasi program, syarat angka keamanan dan batas deformasi dinding penahan tanah ditingkatkan untuk mencegah kemungkinan terburuk terjadi karena kondisi lapangan dan simulasi pada program tidak sepenuhnya sama. Analisis pada program menunjukkan bahwa kondisi drained (SF=2.3394) memiliki angka keamanan lebih kecil dari kondisi undrained (SF=3.5499). Hal ini membenarkan teori bahwa pada kondisi drained, tanah memiliki permeabilitas tinggi sehingga air dapat dengan mudah mengalir keluar masuk pada tanah.

Jalan tol merupakan salah satu jalan bebas hambatan yang keberadaannya saat ini sangat dibutuhkan untuk mempercepat memperpendek waktu tempuh, hal ini akibat  jalan arteri yang sudah ada semakin macet terutama pada saat jam – jam sibuk dan akhir pekan. Dengan semakin padatnya pengguna jalan  tol membuat angka risiko kecelakaan mobil di jalan tol juga semakin meningkat. Dalam upaya meningkatkan keselamatan para pengguna jalan, khususnya jalan tol, Badan Pengatur Jalan Tol (BPJT) telah melaksanakan Audit Keselamatan Jalan (Road Safety Audit). Aspek yang diperiksa meliputi aspek geometrik jalan, manajemen lalu lintas serta geoteknik dan struktur. Sebagai hasilnya, didapatkan kesimpulan bahwa dari segi geometrik, secara umum jalan sudah dirancang sesuai dengan ketentuan, namun demikian ada bagian-bagian yang masih memerlukan penyempurnaan. Penelitian ini akan membahas kondisi eksisting jalan Tol Purbaleunyi berdasarkan pengamatan langsung dan persepsi pengemudi. Aspek yang ditinjau adalah aspek geometrik, perkerasan, dan bangunan pelengkap jalan. Persepsi perngemudi akan didapat dengan melakukan penyebaran kuisioner dan wawancara langsung yang akan diolah dengan menggunakan metode analysis of variance (ANOVA) dibantu dengan program SPSS yang dapat membantu kita untuk mengetahui bagaimana persepsi pengemudi terhadap kondisi eksisting geometrik, perkerasan, dan bangunan pelengkap jalan di jalan Tol Purbaleunyi. Pada akhirnya, akan didapatkan daerah rawan kecelakaan pada ruas tol Purbaleunyi dengan analisis perbandingan dari data persepsi pengemudi, pengamatan langsung, dan data kecelakaan lalu lintas.

Pengendalian penggunaan mobil pribadi menggunakan strategi Electronic Road Pricing, kebijakan parkir dan Transjakarta dapat mengurangi kepadatan lalu lintas. Tujuan dilakukannya penelitian ini adalah untuk menganalisis respon masyarakat terhadap sistem Electronic Road Pricing, kebijakan parkir dan Transjakarta jika diterapkan untuk mengurangi kepadatan lalu lintas. Electronic Road Pricing telah berhasil menanggulangi kemacetan di beberapa negara dengan memberikan tarif berbayar pada jalan tertentu. Sistem kebijakan parkir dapat mengurangi kepadatan lalu lintas dengan menaikan tarif parkir sesuai dengan kepadatan penggunaan kendaraan pribadi di daerah tertentu. Tujuan dari sistem Electronic Road Pricing dan kebijakan parkir agar pengguna kendaraan pribadi beralih menggunakan kendaraan umum untuk mengurangi kepadatan lalu lintas. Pengambilan data untuk penelitian ini diambil dengan cara penyebaran kuesioner di Jalan Raya Serpong kepada responden yang mengetahui dan pernah melewati jalan tersebut. Data yang didapat dari responden, akan diolah agar dapat mengetahui pilihan dari responden tentang kedua sistem tersebut dengan menggunakan model analisis sensitivitas. Strategi parkir, ERP dan Transjakarta dianggap menjadi salah satu solusi untuk mengurangi kepadatan lalu lintas. Hasil dari penelitian ini adalah ketika strategi ERP dan kebijakan parkir diterapkan dengan tarif yang tinggi maka pengguna Jalan Raya Serpong akan beralih menggunakan kendaraan umum dan didapatkan bahwa responden cenderung lebih memilih tarif yang lebih murah.

Indonesia merupakan daerah dengan resiko gempa tinggi, dimana dibutuhkan perencanaan tahan gempa. Struktur penahan gaya gempa secara umum memakai konsep Force Based Design. Konsep dari Force Based Design hanya berdasarkan kondisi elastis struktur dan tidak sesuai dengan kondisi sebenarnya dimana struktur gedung mengalami kondisi inelastis ketika mengalami guncangan gempa. Sehingga perlu dilakukan analisis evaluasi kinerja struktur untuk mengetahui kinerja gedung ketika mencapai kondisi inelastis yang merupakan konsep Performance Based Design. Dalam penelitian ini terdapat dua metode yang dipakai untuk analisis gedung ketika mengalami kondisi inelastis, yaitu metode Direct Displacement Based Design (DDBD) dan metode analisis statik nonlinier Pushover. Tujuan dalam penelitian ini untuk mengindentifikasi hasil output dari kurva kapasitas dan kinerja struktur dari metode ATC-40, FEMA 356, dan FEMA 440, serta membandingkan nilai gaya geser dasar antara SNI 1726:2012 dengan metode DDBD. Tipe struktur bangunan yang dimodelkan berupa bangunan sistem rangka gedung dengan dinding geser. Dari hasil analisis, untuk sistem rangka gedung dengan dinding geser, gaya geser dasar yang diperoleh dari perhitungan dengan metode Direct Dipslacement Based Design lebih kecil dari gaya geser dasar analisis gempa menurut SNI 1726:2012. Dari berbagai metode yang direncanakan sesuai dengan peraturan SNI 1726:2012 menghasilkan level kinerja yang sama menurut ATC-40, FEMA 356, dan FEMA 440 yaitu Immediate Occupancy.
