LIFE LIVED IN LOVE: KONSEP JÜRGEN MOLTMANN MENGENAI ESKATOLOGI PRIBADI | LIFE LIVED IN LOVE: JÜRGEN MOLTMANN’S CONCEPT ON PERSONAL ESCHATOLOGY
Authors: Layantara Jessica Novia 
Published: December 2018

<b>Abstract</b>

This article will focus on describing Moltmann’s view of personal
eschatology, which includes his view on death, the intermediate
state, the resurrection of the dead, and eternal life. The main thesis
of this article is that Moltmann’s view of personal eschatology is
more relevant and applicable to the Christian life here and now.
At the end of this article, the author will give two applications of
Moltmann’s doctrine of personal eschatology. First, Moltmann’s
view of personal eschatology motivates Christians, that they
must live their lives in love, hope, and faith, for they already have
been resurrected and given eternal life, here and now. Secondly,
Moltmann’s focus on the new earth and new heaven in this world,
more than life after death and the traditional concepts of heaven
and hell, should make Christians care about this world and the
life in it.

<b>Keywords:</b> Jürgen Moltmann, Personal Eschatology, Death,
Intermediate State, Resurrection of the Dead, Eternal Life.

<b>Abstrak</b>

Artikel ini terfokus pada deskripsi pandangan Moltmann
tentang eskatologi pribadi, yaitu mengenai kematian, keadaan
peralihan, kebangkitan orang mati, dan kehidupan kekal. Tesis
utama artikel ini ialah pandangan Moltmann tentang eskatologi
pribadi yang lebih relevan dan berlaku untuk kehidupan Kristen
di sini dan saat ini. Pada akhir artikel ini, penulis memberikan
dua aplikasi dari doktrin Moltmann tentang eskatologi pribadi,
yaitu: Pertama, pandangan Moltmann tentang eskatologi pribadi
memotivasi orang Kristen supaya menjalani hidup mereka dalam
cinta, harapan, dan iman, karena mereka sudah dibangkitkan
dan diberikan jaminan kehidupan kekal. Kedua, pandangan
Moltmann mengenai bumi dan surga baru di dunia ini yang lebih
dari kehidupan setelah kematian dan konsep-konsep tradisional
tentang surga dan neraka, membuat orang Kristen peduli terhadap
dunia dan kehidupan di dalamnya.

ESKATOLOGI ISLAM SHIA: ESKATOLOGI DUA DIMENSI | SHIA ISLAMIC ESCHATOLOGY: A TWO DIMENSIONAL ESCHATOLOGY
Authors: Wejak Justin L 
Published: December 2018

<b>Abstract</b>

This paper explains an Islamic eschatology according to Shia,
and suggests that []Shia eschatology always has two dimensions
– religion and politics – and the two dimensions are inseperable.
Discussion surrounding Shia eschatology in this paper is
particularly focused on the Mahdism concept and the figure of
Mahdi. This paper is thus not intended to make a generalisation
about ‘Islamic eschatology’ as if there were only one type of Islam
with a single understanding of eschatology. Most Indonesian
Muslims are of Sunni type of Islam, and may not share the
viewpoint of Shia at all concerning eschatology. The key purpose
of this paper is rather to explore one version of understanding of
eschatology within Islam in order to provoke further reflection on
other perspectives on eschatology.

<b>Keywords:</b> Eschatology, Islam, Politics, Religion, Shia, Sunni,
Prophet Muhammad, Mahdism, Mahdi

<b>Abstrak</b>

Tulisan ini menjelaskan sebuah eskatologi Islam menurut Shia,
dan mengusulkan bahwa versi eskatologi Shia selalu memiliki dua
dimensi – agama dan politik – dan keduanya tak terpisahkan.
Pembahasan mengenai eskatologi Shia dalam tulisan ini khususnya
berfokus pada konsep Mahdisme dan figur Mahdi, menurut versi
Islam Shia. Maka tulisan ini tak dimaksudkan untuk membuat
generalisasi mengenai ‘eskatologi Islam’ seolah ada hanya satu
jenis Islam dengan pemahaman tunggal mengenai eskatologi.
Kebanyakan kaum Muslim Indonesian adalah penganut Sunni,
dan barangkali samasekali tak sependapat dengan pandangan Shia
tentang eskatologi. Tujuan utama tulisan ini sebetulnya untuk
menjelaskan satu versi pemahaman eskatologi dalam Islam agar
memprovokasi refleksi lebih lanjut tentang perspektif-perspektif
lain terkait eskatologi.

POSISI PENTING ORANG DIFABEL DALAM MASYARAKAT | THE IMPORTANT PLACE OF PEOPLE WITH DISABILITIES IN SOCIETY
Authors: Hutagalung Novriana Gloria 
Published: December 2018

<b>Abstract</b>

Making use of the haecceitas theory of Duns Scotus, this text
critiques the statement that every person, and in fact everything
created, and especially people with disabilities, have an individual
uniqueness. This is based upon the uniqueness of the Triune God
who is relational. “Normal” people have self control, can decide
and make personal choices. They can stand on their own two
feet, and they are not dependent on others. The individuality
or personality of a disabled person is often reduced because
the disabled person is regarded as one who cannot do “normal”
activities without assistance. All living creatures are relational
beings because they have been created by and in God who is
relational. The Church witnesses, in the Athanasian Creed, to the
belief that the Triune God is Three separate Persons while being
One in Essence.

<b>Keywords:</b> Disability, Uniqueness, Personality, Trinity

<b>Abstrak</b>

Dengan menggunakan teori haecceitas dari Duns Scotus, tulisan
ini hendak mengulas kenyataan bahwa setiap manusia bahkan
setiap ciptaan, secara khusus orang dengan disabilitas, memiliki
ke-ini-an masing-masing yang bersumber dari ke-ini-an Allah
Trinitas yang relasional. Seorang manusia yang ‘normal’ adalah
orang yang menguasai diri, dapat memutuskan dan menentukan
pilihan bagi diri, mandiri, dan tidak bergantung kepada orang
lain. Individualitas ataupun kepribadian orang dengan disabilitas
sering direduksi karena orang dengan disabilitas dianggap tidak
dapat melakukan aktivitas secara ‘normal’ tanpa dibantu orang
lain. Seluruh makhluk hidup adalah makhluk yang relasional
karena diciptakan oleh dan dalam Allah yang relasional. Gereja
menyaksikan iman, melalui Pengakuan Iman Athanasius, bahwa
Allah Trinitas tidak bercampur dalam Tiga Pribadi (persona) dan
tidak terpisah dalam Esensi-Nya (substantia).

ILMU-ILMU SOSIAL DAN TEOLOGI KONTEKSTUAL | SOCIAL SCIENCES AND CONTEXTUAL THEOLOGY
Authors: Kleden Ignas 
Published: December 2018

<b>Abstract</b>

This text describes the connection between the social sciences
and contextual theology. The social sciences investigate the way
people relate in society via various institutions and structures,
which facilitate relationships in the economic, cultural and
political spheres.The social sciences also investigate the way
human beings relate to nature for two reasons, namely to defend
themselves against the power of nature, and also to enable
them to benefit from nature. Systematic theology studies the
relationship between God and humanity in light of revelation
and faith. Contextual theology investigates to what extent human
institutions and structures, interpersonal relationships and the
relationship between humanity and nature, become a help or a
hindrance to expressing faith in the Lord, and to listening to what
is said by God in God’s revelation to humankind.

<b>Keywords:</b> Social Sciences, Contextual Theology, Society, People,
Institution, Humanity, Relationship, Lord, Structures.

<b>Abstrak:</b>

Tulisan ini bertujuan untuk mendeskripsikan hubungan antara
ilmu-ilmu sosial dan teologi kontekstual. Ilmu-ilmu sosial
menyelidiki hubungan manusia dengan manusia dalam masyarakat
melalui berbagai institusi dan struktur yang memungkinkan dan
memudahkan hubungan itu dalam ekonomi, kebudayaan, dan
politik. Ilmu-ilmu sosial juga meneliti hubungan manusia dengan
alam dalam kaitannya dengan dua tujuan, yaitu mempertahankan
diri terhadap kekuatan alam, dan memanfaatkan alam untuk
keperluan hidupnya. Di sini teknologi dan ekonomi memainkan
peranan yang menentukan. Teologi sistematik meneliti berbagai
aspek relasi Tuhan dengan manusia melalui wahyu serta relasi
manusia dengan Tuhan melalui iman. Teologi kontekstual
meneliti sejauh mana institusi dan struktur yang dibangun
manusia, baik dalam relasi antar-manusia maupun dalam relasi
manusia dan alam, menjadi fasilitas atau hambatan baginya dalam
menyatakan iman kepada Tuhan, dan dalam mendengarkan apa
yang disampaikan Tuhan dalam wahyu-Nya kepada manusia.

Alloy Cast Irons
Authors: Gundlach Richard B. , Doane Douglas V. 
Published: December 2018

Abstract
Alloy cast irons are considered to be those casting alloys based on the iron-carbon-silicon system that contain one or more alloying elements intentionally added to enhance one or more useful properties. Alloy cast irons can be classified as white cast irons, corrosion-resistant cast irons, and heat-resistant cast irons. This article discusses abrasion-resistant chilled and white irons, high-alloy corrosion-resistant irons, and medium-alloy and high-alloy heat-resistant gray and ductile irons. The article outlines in a list the approximate ranges of alloy content for various types of alloy cast irons. The article explains the effects of alloying elements and the effects of inoculants. In most cast irons, it is the interaction among alloying elements that has the greatest effect on properties. Inoculants other than appropriate graphitizing or nodularizing agents are used rarely, if ever, in high-alloy corrosion-resistant or heat-resistant irons.

This article examines the most common precoating methods and provides a metallurgical understanding of how they impact the manufacturability, performance, and service life of the host material. The article covers metallic coatings, including zinc, aluminum, zinc-aluminum alloys, tin, and terne; pretreatment or phosphate coatings; and preprimed and painted finishes based on organic coatings.
Hot-Rolled Steel Bars and Shapes
Authors: Moss Timothy E. , Hambright J.M. , Murphy T.E. , Schmidt J.A. 
Published: December 2018

Abstract
Hot-rolled steel bars and other hot-rolled steel shapes are produced from ingots, blooms, or billets converted from ingots or from strand cast blooms or billets and comprise a variety of sizes and cross sections. Most carbon steel and alloy steel hot-rolled bars and shapes contain surface imperfections with varying degrees of severity. Seams, laps, and slivers are probably the most common defects in hot-rolled bars and shapes. Another condition that could be considered a surface defect is decarburization. Hot-rolled steel bars and shapes can be produced to chemical composition ranges or limits, mechanical property requirements, or both. Hot-rolled carbon steel bars are produced to two primary quality levels: merchant quality and special quality. Merchant quality is the least restrictive descriptor for hot-rolled carbon steel bars. Special quality bars are employed when end use, method of fabrication, or subsequent processing treatment requires characteristics not available in merchant quality bars.
High-Strength Low-Alloy Steel Forgings
Authors: Wright Peter H. 
Published: December 2018

Abstract
Two high-strength low-alloy (HSLA) families, acicular-ferrite steels and pearlite-reduced steels, contain microalloying additions of vanadium and niobium. Vanadium, niobium, and titanium combine preferentially with carbon and/or nitrogen to form a fine dispersion of precipitated particles in the steel matrix. This article summarizes the metallurgical effects of vanadium, niobium, molybdenum, and titanium. The metallurgical fundamentals were first applied to forgings in the early 1970s. The ultimate strength of first- and second-generation microalloy steels is adequate for many engineering applications, but these steels do not achieve the toughness of conventional quenched and tempered alloys under normal hot-forging conditions. Third-generation microalloy steels differ from their predecessors in that they are direct quenched from the forging temperature to produce microstructures of lath martensite with uniformly distributed temper carbides. Without subsequent heat treatment, these materials achieve properties, including toughness, similar to those of standard quenched and tempered steels.
Machinability of Steels
Authors: Boulger Francis W. 
Published: December 2018

Abstract
The machinability of carbon and alloy steels is affected by many factors, such as the composition, microstructure, and strength level of the steel; the feeds, speeds, and depth of cut; and the choice of cutting fluid and cutting tool material. This article describes the influence of the various attributes of carbon and alloy steels on machining characteristics. It lists the relative machinability ratings for some plain carbon steels, standard resulfurized steels, and several alloy steels. The addition of lead to carbon steels is one of the means of increasing the machinability of the steel and improving the surface finish of machined parts. Low carbon content of carburizing steels may be beneficial to tool life and production rate. The sulfur content of through-hardening alloy steels can significantly affect machining behavior. Cold drawing generally improves the machinability of steels containing less than about 0.2% carbon.
Notch Toughness of Steels
Authors: Roe G.J. , Bramfitt B.L. 
Published: December 2018

Abstract
Notch toughness is an indication of the capacity of a steel to absorb energy when a stress concentrator or notch is present. The notch toughness of a steel product is the result of a number of interactive effects, including composition, deoxidation and steelmaking practices, solidification, and rolling practices, as well as the resulting microstructure. All carbon and high-strength low-alloy (HSLA) steels undergo a ductile-to-brittle transition as the temperature is lowered. The composition of a steel, as well as its microstructure and processing history, significantly affects both the ductile-to-brittle transition temperature range and the energy absorbed during fracture at any particular temperature.. Th article focuses on various aspects of notch toughness including the effects of composition and microstructure, general influence of manufacturing practices and the interactive effects that simultaneously influence notch toughness. With the exception of working direction, most of the same chemical, microstructural, and manufacturing factors that influence the notch toughness of wrought steels also apply to cast steels. The Charpy V-notch test is used worldwide to indicate the ductile-to-brittle transition of a steel. While Charpy results cannot be directly applied to structural design requirements, a number of correlations have been made between Charpy results and fracture toughness.
