Authors: Indriastiningsih Erna , Hafid Ridlo Nugroho Muhammad
Published: March 2019

PT. XYZ merupakan perusahaan manufaktur yang memproduksi kemasan kaleng sebagai produk utama. Selain memproduksi kaleng kemasan, PT. XYZ juga memproduksi tolling/ spare part mesin untuk digunakan pada lini produksinya. Spare part merupakan bagian komponen mesin produksi yang diproduksi pada workshop departemen melalui beberapa proses permesinan seperti lathe, fraise, dan wire cut, grinding baik melalui mesin manual maupun CNC. Untuk menghasilkan kualitas spare part dan tolling yang presisi (0,001 mm) maka digunakan mesin CNC. Namun dalam pengggunaannya, mesin CNC ini sering mengalami breakdown sehingga mesin tersebut tidak dapat beroperasi. Setelah dilakukan pengamatan, mesin yang sering mengalami breakdown adalah pada mesin HASSTM3. Penelitian ini bertujuan untuk menghitung efektifitas mesin CNC HASS-TM3 menggunakan metode Overall Equipment Effectiveness (OEE). OEE merupakan suatu metode yang digunakan untuk mengukur efektivitas suatu mesin atau peralatan. Data yang digunakan dalam penelitian ini terdiri dari data primer dan data sekunder. Data primer berisi hasil wawancara dengan operator HASS TM-3 dan teknisi listrik tentang penyebab breakdown mesin tersebut, sedangkan data sekunder berisi tentang data jam kerja, perawaatan mesin, delay mesin, data produksi mesin. Hasil perhitungan OEE bulan Desember 2015 – November 2016 menunjukkan bahwa efektivitas mesin HASS-TM3 masih rendah yaitu berkisar antara 55,12%-74,08%. Penyebab utama rendahnya nilai OEE mesin HASS-TM3 adalah keterlambatan maintenance mesin, sehingga tidak beroperasi lama yang menyebabkan rendahnya nilai availability.

Limbah ampas tebu periode giling tahun 2016 dapat digunakan sebagai bahan bakar ketel uap pengganti solar selama 3266,18 jam atau 165,44 hari. Penghematan biaya yang dapat dicapai oleh perusahaan dengan memanfaatkan limbah ampas tebu sebagai bahan bakar ketel uap sebagai pengganti solar sebesar Rp 614. 354. 330,80.
Analisis Pengaruh Shift Kerja terhadap Beban Kerja Mental pada Operator Air Traffic Control (ATC) dengan Metode NASA-TLX (Studi Kasus: Bandar Udara Internasional X)
Authors: Amanda Putri Rizka , Tambunan Willy , Dianati Fathimahhayati Lina
Published: March 2019

Pelayanan navigasi membutuhkan ketelitian dari seorang operator Air Traffic Control (ATC) untuk melakukan proses scanning pada air situation display dalam mengatur lalu lintas pesawat yang akan take off dan landing di Bandar Udara Internasional X dan pesawat overflying di bawah FL245 di area Balikpapan TMA serta semua penerbangan dari dan yang akan menuju Bandar Udara di Samarinda. Kegiatan ini termasuk ke dalam pekerjaan yang membutuhkan kerja mental. Selain itu, kepadatan lalu lintas udara setiap waktu pastinya berbeda-beda yang mungkin akan mempengaruhi tingkat ketelitian operator dalam melakukan kegiatan pemantauan. Berdasarkan permasalahan tersebut, maka dilakukan pengukuran beban kerja mental operator ATC. Pengukuran beban kerja mental pada penelitian ini menggunakan NASA –TLX dengan tiga kondisi kerja yang berbeda yaitu shift pagi pada pukul 7.30-13.30 WITA, shift siang pada pukul 13.30-19.30 WITA, dan shift malam pada pukul 19.30-7.30 WITA. Hasil penelitian menunjukkan bahwa beban kerja mental operator ATC pada shift pagi masuk ke dalam kategori beban kerja mental tinggi sekali dengan skor 81, shift siang masuk ke dalam kategori beban kerja mental tinggi dengan skor 77, dan shift malam masuk ke dalam kategori beban kerja mental tinggi dengan skor 77. Shift kerja memiliki pengaruh terhadap beban kerja mental operator ATC karena disebabkan oleh kepadatan traffic yang terjadi pada tiga kondisi kerja yang berbeda yaitu shift pagi sebanyak 80 sampai 100 lebih traffic, shift siang sebanyak 20-80 traffic dan shift malam sebanyak 0-20 traffic. Rekomendasi yang dapat diberikan terhadap perolehan beban kerja mental yang cukup tinggi ini adalah melalui pembagian wilayah pada Balikpapan TMA, penambahan Sumber Daya Manusia (SDM), serta penyediaan tempat istirahat yang memadai dan fasilitas di dalamnya.

Human resources (HR) or labor are the main assets in an organization, need special treatment in the management of labor because the basis is labor can affect the existence of the organization in the future. The management of a good workforce will be able to create an optimal working atmosphere in order to realize the productivity of the workforce in the organization. There are many factors that can affect employee performance in work, including the process of recruitment and giving motivation to employees. The process of employee recruitment requires good planning related to the organization's needs for labor and needs a good analysis in placing a worker in a position that is in accordance with his competence. Furthermore, giving motivation is another important factor in improving employee work outcomes. Giving motivation by an organization is an obligation and demand, with good and continuous motivation in the form of direction or appreciation to employees can provide stimulation to employees to work better in order to achieve organizational goals that have been set.
Severe violations of independence in response inhibition tasks
Authors: Bissett Patrick , Jones Henry Morrow , Poldrack Russell , Logan Gordon D.
Published: March 2019

The stop-signal paradigm, a primary experimental paradigm for understanding cognitive control and response inhibition, rests upon the theoretical foundation of race models, which assume that a go process races independently against a stop process that occurs after a stop-signal delay (SSD). We show that severe violations of this independence assumption at short SSDs occur systematically across a wide range of conditions, including fast and slow RTs, auditory and visual stop signals, manual and saccadic responses, and especially in selective stopping. We also reanalyze existing data and show that conclusions can change when short SSDs are excluded. Finally, we suggest experimental and analysis techniques to address this violation, and propose adjustments to extant models to accommodate this finding.
Land Tenure and Missing Women: Evidence from North India
Authors: Lal Apoorva
Published: March 2019

While a substantial literature documents a robust positive relationship between property rights and economic growth, the effects of institutions on demographic and socio- political outcomes are less well understood. This paper studies this relationship by using variation in property rights systems induced by historically contingent assignment of districts in North Indian state of Uttar Pradesh to study their effects on modern day demographic outcomes. We find that villages where property rights were granted to the cultivators have more skewed sex-ratios, lower female literacy, and lower female labor force participation rate than villages where property rights were granted to the landlord. These findings suggest that, in contrast to the robust positive relationship between institutions and economic outcomes, economic institutions may, depending on existing social norms, ameliorate or exacerbate social inequalities.
Appraisal Practices in Web Archives
Authors: Summers Edward
Published: March 2019

This paper explores the art and science of deciding what web archives collect by reviewing the literature of archival appraisal through the theoretical lens of Science and Technology Studies. I suggest that our anxieties around what web archives remember and forget, get embodied in dreams (and nightmares) of Big Data and The Cloud. These notions are best understood by attending to the specific material practices of people working with memory and machines. The disciplinary perspective of software studies can provide insight into how these material practices of appraisal operate in response to, and outside of traditional conceptions of the archive, and also as an instrument of governmentality.
Multiplatform MOOC Analytics: Comparing Global and Regional Patterns in edX and Edraak
Authors: Ruipérez-Valiente José A. , Halawa Sherif , Reich Justin
Published: March 2019

While global massive open online course (MOOC) providers such as edX, Coursera, and FutureLearn have garnered the bulk of attention from researchers and the popular press, MOOCs are also provisioned by a series of regional providers, who are often using the Open edX platform. We leverage the data infrastructure shared by the main edX instance and one regional Open edX provider, Edraak in Jordan, to compare the experience of learners from Arab countries on both platforms. Comparing learners from Arab countries on edX to those on Edraak, the Edraak population has a more even gender balance, more learners with lower education levels, greater participation from more developing countries, higher levels of persistence and completion, and a larger total population of learners. This "apples to apples" comparison of MOOC learners is facilitated by an approach to multiplatform MOOC analytics, which employs parallel research processes to create joint aggregate datasets without sharing identifiable data across institutions. Our findings suggest that greater research attention should be paid towards regional MOOC providers, and regional providers may have an important role to play in expanding access to higher education.
Social dilemmas in the sharing economy
Authors: Corten Rense
Published: March 2019

While it is widely acknowledged that trust plays an important role in the sharing economy, it is often confused with other strategic considerations related to cooperation in sharing economy interactions. In this chapter I propose that social dilemma research, rooted in game theory, offers a rich and flexible theoretical framework for studying sharing economy interactions. I sketch applicable models that may involve trust as an important feature of many sharing economy interactions but also highlight other strategic considerations that superficially look similar to trust problems but may be understood more fruitfully by alternative models. More specifically, I discuss various types of two-person dilemmas such as the Prisoner’s Dilemma and the Trust Game, but also N-person dilemmas, including common pool problems, exchange systems, and club goods. Solutions to the cooperation problems implied by these dilemmas are also discussed. I conclude the chapter by sketching some promising directions for future research.
Ford and the New Auto Industry
Authors: Arroyo Jose Daniel
Published: March 2019

The iconic Ford Motor Company is considered one of the pillars of the automotive industry. Its first vehicle, the Model T, introduced the concept of mass production and automobile affordability to the masses. Today, the market is full of domestic and foreign competitors, yet, Ford has struggled to remain competitive, even though it promotes itself as America’s best-selling brand. Its stock was recently downgraded, and recently, it announced its intentions to only sell sports utility vehicles, trucks, Mustangs and Focus, in other words, it will stop selling most of its passenger cars. Conversely, Toyota continues to lead the market in passenger car sales, while newcomer Tesla struggles to deliver on its backlog of 500,000 electric vehicle orders. Ford has strong brand equity, has automated production facilities and a large franchised dealer network across the globe. Yet, it is rapidly losing passenger car market share, its profits are eroding, and its new vision is confusing. Furthermore, the company is facing a significant threat from well capitalized new competitors entering from the tech industry. The company, on the other hand, has enjoyed significant success in mainland China, where the demand for American automobiles continuous to be strong. Yet, the company needs to assume a cost leadership position and attempt to use this strategy to increase market share. The contention in this paper is that an adequate approach for the company appears to be a combination of market penetration in the domestic front, market expansion in Asia and other parts of the globe, and a product development approach that ushers cost reductions.

Published: March 2019

Nepal is considered as one of the earthquake-prone countries in the region. Earthquake is a major concern of Nepal because of rapid population growth, poor land use planning, precarious settlement patterns, and poorly implemented building code. Earthquakes in Nepal have been reported since 1255 while major earthquakes were recorded in 1408, 1681, 1810, 1833, and 1866, 1934, 1980, 1988, 2011, and 2015. An earthquake in September 18, 2011 measuring 6.9 in Richter scale, killed 6 people and injured 30 people in Nepal. There were many roadside slope damages near the epicenter area. To assess the roadside slope damages after this earthquake, a field visit was conducted and a landslide inventory map along the roadside slope was prepared for most damaged area. This paper provides a comprehensive information about earthquake-induced slope failures occurred in the Mechi Highway of eastern Nepal and also discusses an approach of earthquake-induced slope failures hazard mapping in Nepal.

Due to metacognition, as a psychological concept, has been a focus of educational researchers and become a potential to empower students to improve their own learning; increase the meaningfulness of learning, especially among students who are having problems in learning; and become successful learners, the present paper implicatively investigates the possible role of metacognitive instruction in developing ESL/EFL listening abilities among students by providing theoretical and empirical foundations drawn from the literature. To elicit the purpose of this article, the literature study was used. This study reviewed several recent research papers in the last 10 years related to the implementation of metacognitive instruction in order to elicit the information of the possibilities in developing ESL/EFL students’ listening comprehension abilities. Based on a detailed analysis and review of the research articles, there were some themes related to the possibility role of implementing the instruction not only developing ESL/EFL listening abilities, but also metacognitive knowledge and metacognitive awareness. Moreover, the instruction enables ESL/EFL students to increase their awareness of the listening process by improving richer metacognitive knowledge about themselves as listeners, the nature and demands of listening tasks, and listening strategies. This instruction they may encourage them to have an ability to regulate their own learning in and outside ESL/EFL classrooms. Therefore, based on the literature review  and analysis above, ESL/EFL teachers will regard the important role of metacognition and attempt to implement the instruction as an alternative of effective teaching ways to develop ESL/EFL students’ listening abilities in and outside the classroom independently, particularly in the context of higher education in Indonesia.

Isus Krist – Početnik i Dovršitelj vjere
Authors: Kalem Hrvoje
Published: March 2019

Pitanje vjere sržno je teološko i egzistencijalno pitanje. Vjernikova vjera ima svoj uzor u Isusovoj vjeri na koju se slabo ukazivalo u povijesti teologije. Obnovljeno promišljanje o fides Christi započinje se s Hansom Ursom von Balthasarom i to u njegovu istoimenom djelu. Na tragu njegove misli u članku se promišlja o novozavjetnoj vjeri kao upotpunjenju starozavjetne. U drugom koraku donosi se misao o Kristovoj vjeri do koje se dolazi fenomenološkim putem, promatrajući Isusov odnos prema Ocu kako ga opisuje Novi zavjet. Iz toga će postati razvidno da je Isusov odnos prema Ocu paradigma svakoga vjerničkoga odnosa prema Bogu, što je tema trećega dijela ovoga članka. U zadnjem koraku artikulira se pitanje vjere u eshatonu pokazujući da je vjera potrebna i u gledanju Boga licem u lice jer se Otajstvo nikada ne može iscrpiti. Nakon rezimea članak kratko upućuje na vjeru kao put svetosti na koji nas poziva Božja svetost.
Skica kristološko-trinitarne hermeneutike pakla i dužnosti nade u spas svih ljudi u misli H. U. von Balthasara
Authors: Vulić Boris
Published: March 2019

Čini se da je posljednja velika uistinu teološka diskusija vođena oko teze švicarskoga teologa Hansa Ursa von Balthasara o nadi u spas svih ljudi. Nakana je ovoga članka ponajprije podsjetiti na temeljne sadržaje toga prijedloga. Tako u prvom poglavlju prikazujemo novozavjetna mjesta i teološke momente koje ovaj švicarski teolog uzima za polazišta i opravdanja svoga uvjerenja o dužnosti kršćanske nade u sveopći spas. Ipak, temeljna je teza članka da je konačna pozadina takve nade Balthasarova kristološko-trinitarna hermeneutika pakla, u kojoj pakao postaje poduhvaćen Kristom i zato kristološko mjesto milosti. Upravo se ta konačna pozadina, čiju skicu donosimo u drugom poglavlju, u većini prikaza na hrvatskom jeziku propušta uočiti kao temeljna premisa nade u spas svih ljudi. Spomenuta originalna hermeneutika dovela je Balthasara do uvjerenja da Božje milosrđe po Kristovu križu zauzima mjesto pravednosti, čime se bavimo u trećem i ujedno posljednjem poglavlju članka. U zaključnim mislima ukazujemo na važne doprinose Balthasarovih promišljanja o sveopćoj nadi, poput ozbiljnosti vjerske istine o paklu, osobnom karakteru mogućnosti pakla (pakao za mene) te o Bogu koji je uvijek posljednja čovjekova stvarnost, pa i onda kad je vječno izgubljen. Također otkrivamo i neka dvojbena ili problematična mjesta Balthasarove misli koja valja prepoznati kao nove perspektive za daljnja kritička istraživanja.
Depopulacija i starenje u Istočnoj Hrvatskoj
Authors: Živić Dražen
Published: March 2019

Predmet istraživanja u ovom radu jest ukupno kretanje stanovništva i suvremene promjene u biološkoj strukturi stanovništva Istočne Hrvatske. Svrha istraživanja jest na temelju rezultata dvaju posljednjih popisa stanovništva (2001. i 2011.), analize vitalne statistike za razdoblje 2001. – 2016. te projekcija budućega kretanja stanovništva (do 2030., odnosno 2051.) utvrditi, analizirati i interpretirati osnovne agregatne pokazatelje koji indiciraju trendove u općem, prirodnom i mehaničkom kretanju stanovništva Istočne Hrvatske te njihovu interakcijsku povezanost uz proces demografskoga starenja. Cilj je rada utvrditi i opisati dosegnutu razinu ukupne depopulacije i demografskoga starenja Istočne Hrvatske. S obzirom na to da se opći i parcijalni procesi depopulacije nalaze u snažnom korelativnom odnosu spram oblikovanja biološke strukture stanovništva, jasno je da oni zajedno čine dalekosežne regresivne čimbenike populacijskoga, a time i društveno-gospodarskoga razvoja Istočne Hrvatske. Ako se nastave dosadašnji nepovoljni demografski trendovi, osobito u bioreprodukciji, realno se može očekivati da će Istočna Hrvatska do sredine 21. stoljeća prirodnim i mehaničkim putem izgubiti trećinu stanovništva popisanoga 2011. godine. Očekivani daljnji pad broja stanovnika ne će biti linearan, nego se očekuje jačanje debalansa u odnosu između pojedinih velikih (funkcionalnih) dobnih kontingenata, osobito u odnosu: mlado – staro stanovništvo.
HALKEVLERİ’NDE EĞİTİCİ SİNEMA REPERTUARI: ERKEN CUMHURİYET TÜRKİYESİ’NDE SİNEMA, EĞİTİM, PROPAGANDA (1923-1945)
Authors: ÇELİKTEMEL-THOMEN Özde
Published: March 2019

Halkevleri’nde Eğitici Sinema Repertuarı, 1923-1945 yıllarında Cumhuriyet Halk Partisi’nin (CHP) Kemalist ideolojiyi desteklemek için Halkevleri’nde başlattığı eğitici/öğretici ve propaganda amaçlı film gösterimlerinin izini sürer. Makalenin çıkış noktası, Halkevleri’nde 1932’de filizlenen, devlet güdümlü sinema girişimini tarihselleştirmektir. Sözü geçen haber ve seyahat filmlerinin, eğitici/öğretici filmlerin ve diğer belgesellerin çoğu CHP’nin bizzat çektirdiği veya kiraladığı filmlerdir. Bu çalışmanın temelde iki önemli iddiası bulunuyor: Birincisi siyasal ve resmi elit, öncelikle yetişkinleri hedef alarak eğitici/öğretici filmler aracılığıyla (i) ulusal kimlik inşasını, (ii) siyasal liderlerin meşruiyetini ve (iii) Kemalist ideolojiyi yaymayı ve güçlendirmeyi hedeflemiştir. Bu bağlamda Halkevleri kültürel boyutta, Louis Althusser’in tarif ettiği “devletin ideolojik aygıtı” haline gelmiş ve “somut bireylerin birer özne” olarak egemen siyasal görüşü benimsemelerinde rol oynamıştır. İkincisi Halkevleri, özel sinema salonları dışında, sinema için yeni bir kamusal alan oluşturmuştur. Bu araştırmanın ilk bölümünde, tarihsel altyapıyı oluşturmak için Türkiye’deki sinemalar, filmler ve seyirciler çağdaşlarıyla karşılaştırılarak değerlendiriliyor. Bu çalışma, arşiv belgelerine dayalı, niceliksel ve niteliksel temsili örneklemlerle oluşturulan bir tarihsel anlatı denemesidir. Devlet tutanakları, önergeler, yazışmalar ve kararnamelerden derlenen veriler dışında, mevcut birkaç film incelenmektedir. Filmlerin seyirci tarafından alımlanması ve film yapımının tekniği ise yazıya dahil edilmemektedir.
