Alkali Activation of Metakaolin and Wollastonite: Reducing Sodium Hydroxide Use and Enhancing Gel Formation through Carbonation
No full textAbstract
Alkali activated materials (AAMs) offer significant advantages over traditional materials like Portland cement, but require the use of strong alkaline solutions, which can have negative environmental impacts. This study investigates the synthesis of AAMs using metakaolin and wollastonite, aiming to reduce environmental impact by eliminating sodium silicate and using only sodium hydroxide as an activator. The hypothesis is that wollastonite can provide the necessary silicon for the reaction, with calcium from wollastonite potentially balancing the negative charges usually countered by sodium in the alkaline solution. This study compares raw and carbonated wollastonite (AAM-W and AAM-CW) systems, with raw materials carefully characterized and binding networks analyzed using TGA, FT-IR, and XRD. The results show that while wollastonite can reduce the amount of sodium hydroxide needed, this reduction cannot exceed 50%, as higher substitution levels lead to an insufficiently alkaline environment for the reactions. The carbonation of wollastonite enhances the availability of silicon and calcium, promoting the formation of both N-A-S-H and C-A-S-H gels.Abstract

Mengenal Allah Lewat Energi Tidak Dengan Esensi
No full textAbstract:The energy of God is the radiance of divine love bestowed upon every human being who acts in accordance with what God has spoken and desired. But it cannot be denied that on the part of man there are still some people who are constantly trying to explain the essence of God through ratio and reason, resulting in man doubting his faith in God. But it cannot be denied that on the part of man there are still some people who are constantly trying to explain the essence of God through ratio and reason, resulting in man doubting his faith in God. This study aims to explain that human limitations cannot explain God who is not limited by time and space, but because of His grace God reveals himself to man through incarnation so that man can feel God's love at every moment. In writing this article, the author uses a literature review method that is carried out based on data in the form of Bible studies, journals, and opinions of Church Fathers. The results of this study prove that the knowledge of the true God is only through the word of God who has been incarnated into man.Abstrak:Energi Allah merupakan pancaran kasih ilahi yang di anugerahkan kepada setiap manusia yang bertindak sesuai dengan apa yang difirmankan oleh Allah dan dikehendaki Allah. Namun tidak bisa di pungkiri bahwa di pihak manusia masih terdapat beberapa orang yang terus berusahan menjelaskan esensi Allah melalui rasio dan akal budi, sehingga mengakibatkan manusia ragu akan imannya terhadap Allah. Penelitian ini bertujuan untuk memberi penjelasan bahwa keterbatasan manusia tidak bisa menjelaskan Allah yang tidak dibatasi oleh ruang dan waktu, namun oleh karena anugerah-Nya Allah menyingkapkan diri kepada manusia melalui inkarnasi sehingga manusia bisa merasakan kasih Allah disetiap saat. Dalam penulisan artikel ini penulis menggunakan metode kajian literatur yang dilakukan berdasarkan data berupa telaah Alkitab, jurnal, dan pendapat para Bapa Gereja. Hasil penelitian ini membuktikan bahwa pengenalan Allah yang benar hanya melalui firman Allah yang telah berinkarnasi menjadi manusia

Uzbeks and Kazakhs in Fazl Allah Khunji’s Mihmannamah-i Bukhara
No full textThis chapter looks at another Persian historian, Fazl Allah b. Ruzbihan Khunji (d. 1519), in his journey to Central Asia and his attempt to justify the Uzbek ruler Shibani Khan (d. 1510) in his disastrous campaign against the Kazakhs of Turkestan. Fazl Allah had to project onto his master’s kinsmen/enemies all the negative associations of a Turkic ancestry in order to justify their murder and enslavement. However, this projection created difficulties for the author as well because he knew that his Shibanid patrons were actually related to the Kazakhs across the river in Turkestan. Thus even in Central Asia itself, Turco-Mongol origins were problematic.</p

A Commentary (ممزوج ) on Abu’l-Ḳâsim Maḥmûd b. ‘Omar Zamakhsharî’s (d. A.H. 538) رسالة التصرفات , or treatise on Particles and the Inflection of Nouns , by MUḤAMMAD ‘IṢMAT ALLAH b. Maḥmûd Ni’mat Allah BUKHÂRÎ, who wrote it A.H. 945.
As the author states himself, the treatise commented on is only a portion of Zamakhsharî’s المقدّمة , i.e. مقدّمة الادب ; and it comprises Parts ( قسم ) III. and IV. of this work. See regarding the latter, Ḥ. Kh. vi. 76; Cat. Bodl. ii. 186; Fleischer, Cat. Lips 332; etc. The first three parts of it have been edited by Dr. Wetzstein (Samachscharii Lexicon Arabicum Persicum, etc., Lips 1850, autographed).
The preface begins:
حمدا لمن فتح ابواب العلوم على اولى الالباب الخ
and the author concludes as follows:
تم ما قصدت جمعه فى هذا الكتاب .... رحم الله لمن دعا لمؤلّفه الفقير الراجى الی رحمة الله البارى محمد عصمة الله محمود ابن 1 نعمة الله البخارى اسكنهما الله جوار رحمته و البسهما لباس مغفرته انه قدير باجابة دعاء الفقير فى وقت الظهر من يوم الاحد العاشر للصفر سنة خمس و اربعين و تسعمائة من الهجرة الخ
This MS. appears to have been transcribed from the author's own copy. It is neatly written in Nasta’lîḳ, and has corrections and notes by the author on the margin; the latter conclude invariably with منه عفى عنه , only the first note has منه مدّ ظلّه instead.
Two prayers are added on the title-page by the original hand. Worm-eaten.

Karya Allah Pada Masa Intertestamen
No full textFrom the word submitted by the prophet Malachi (432 BC) to the angel of God speaking to the priest Zechariah, his father John the Baptist, is estimated to be about 400 years. And over that long period of time, what really happened? Is God indeed dwelling? Or is God preparing for the coming of the Messiah? Or God is angry with His people, who continue to sin? These questions are certainly the mainstays of the theologians to do research. The author tries to collect data from previous studies of historical events, archeological results, and Biblical text. Thus it can be deduced a conclusion, what is actually happening in the grace period of 400 years. Research begins from the years before, during the intertestament and thereafter. The most likely to be studied is the history of Persian media, Greek (Hellenistic), Jews regain Jerusalem (Maccabees struggle) and the formation of the Roman empire. After doing research it turns out in history and events it is found that God plays an active role. The fulfillment of Daniel, Hosea and Malachi\u27s prophecies occurred during the intertestament. Even supernatural things, which would not have been possible if God had not intervened, had occurred. This research will certainly convince all readers, that God is still working and in control in every age. Dari perkataan nubuat nabi Maleakhi (432 SM) hingga malaikat Tuhan berbicara kepada Imam Zakaria, bapaknya Yohanes pembaptis diperkirakan 400 tahun.Dan sepanjang periode waktu yang panjang tersebut, apakah yang terjadi?Apakah Allah berdiam diri? Atau apakah Ia sedang mempersiapkan kedatangan Mesias? Atau Allah marah terhadap umat-Nya yang terus hidup dalam dosa?Pertanyaan-pertanyaan ini yang seringkali menjadi perdebatan para teolog.Penulis mencoba mengumpulkan dari peristiwa-peristiwa sejarah yang telah diteliti sebelumnya, hasil-hasil arkelogi, dan teks Alkitab yang berkaitan. Kemudian dapat diambil suatu kesimpulan, apa yang sebenarnya trjadi dalam periode 400 tahun tersebut. Penelitian dimulai dari tahun-tahun sebelum, selama dan setelah masa intertesmen.Hal-hal yang dipelajari meliputi sejarah Media Persia, Yunani (Helenisasi), kembalinya orang Yahudi ke Yerusalem (pemberontakan Makabe) dan terbentuknya kerajaan Romawi.Setelah melakukan penelitian, maka diperoleh realitas bahwa Allah berperan secara aktif dalam masa tersebut.Penggenapan Nubuat dalam Daniel, Hosea dan Maleaki terjadi pada masa intertestemen.Bahkan hal-hal yang supranatural, yang tidak mungkin terjadi, jika bukan Allah yang mengintervensi hal-hal yang terjadi tersebut.Hasil penelitianini tentu menyakinkan para pembaca bahwa Allah masih dan sedang bekerja dan mengontrol dalam segala zaman

An anonymous Commentary (ممزوج) on the theosophic treatise, التحفة المرسلة الى النبىّ , by MUḤAMMAD B. FAḌL ALLAH Hindi Burhânpûrî (d. A.H. 1029). The latter was a disciple of Shaikh Wajîh al-dîn b. Ḳâḍi Naṣr Allah ‘Alawî Hindi Aḥmadâbâdi, who lived from A.H. 910 to 998, and was the pupil of Shaikh Muḥammad b. Khaṭîr al-din Ḥusainî, commonly called al-Ghauth, the author of الجواهر الخمسة (see above, no. 671). A co-disciple of the author’s, Shaikh of Ṣibghat Allah b. Rûḥ Allah b. Jamâl Allah Ḥusainî Hindî Barûjî, who died at Madînah, was the Shaikh of Abu’l-mawâhib Aḥmad b. ‘Alî b. ‘Abd al-ḳuddûs Ḳurashî ‘Abbâsî Shinnâwî Madanî, and a pupil of the latter was شيخنا الامام ثم الهدلى الانصارى المعروف بالقشار طيفى (!) الدين احمد بن يونس بن احمد المقدسى الرجالى ثم المدنى الانصارى المعروف بالقَشارى (!)1 , who was born A.H. 991, and died A.H. 1071, at Madînah, and was the Shaikh of the author of the present commentary. The latter, therefore, lived in the eleventh century, probably at Madinah. His name is not mentioned, His commentary is entitled اتحاف الزكىّ بشرح التحفة المرسلة الى النبىّ . He wrote it for the instruction of the Muḥammadans of Java, whose notions of orthodoxy had recently been troubled by the introduction of Ṣûfî writings, which their divines were not able to interpret. He, therefore, selected the present treatise, which was very popular with them, in order to show its entire accordance with the doctrines of the Koran and the Sunnah.
The preface begins:الحمدلله الاول الذى ليس قبله شئ . The commentary refers only to the commencement of the treatise, and its chief subject is the absolute essence (الوجود) .
The treatise begins:الحمد لله رب العالمين اما بعد فيقول العبد .. 2 هذه نبذة من الكلمات فى علم الحقائق الخ.
Well written, of about A.H. 1100. The text of the treatise has been added at the end, by a different hand; the greater part of it is, however, lost.

Mineraalien karbonoinnin ja alkaliaktivoinnin soveltamismahdollisuudet Mg-rikkaiden rikastushiekkojen hyödyntämisessä
No full textCO₂ levels in the atmosphere has raised concerns about its influence on climate change. At the same time, mine tailings present a significant environmental problem for the mining industry. In the existing literature, two environmentally friendly technologies, CO₂ sequestration and Alkali activation are widely employed to solve these challenges. The technologies are however decoupled. Thus, this study explores the simultaneous use of both methods to solve both environmental problems: first through CO₂ sequestration using mineral carbonation of mine tailings, and then the valorization of CO₂-treated mine tailings using alkali activation. Batch experiments were first conducted to determine the leachability of Mg–rich tailings to extract Mg and Ca for carbonation. The residues of the batch experiments were dissolved in strong alkaline solution to determine their reactivity. The results indicated that the Mg-rich tailings can serve as good feedstock for Mg and Ca cations for carbonation. The Si-rich residues obtained can be activated to form a geopolymer, according to activation test. This study reveals that alkali activation and mineral carbonation can be coupled to solve both environmental problems presented by CO₂ and mine tailings. Thus, after leaching several tons of magnesium or calcium silicates from tailing, their residues can be utilized for the formation of alkali activated products
MEMAHAMI PEMELIHARAAN ALLAH DALAM BENCANA GAGAL PANEN DI DAERAH SA’DAN TIROALLO BERDASARKAN MODEL BERTEOLOGI KOSUKE KOYAMA
No full textRecognition of God's love and care is not enough through fellowship but also through disasters in life, one of which is crop failure. This research aims to discover and understand the form of God's providence through crop failure disasters based on God's will, which is present in human life. Several theories used by the author include disaster theory, Kosuke Koyama's theology, and theories about God, which several authors have summarized. The research method used by the author is qualitative with a descriptive approach. Qualitative was developed through a literature study sourced from relevant book literature, articles and internet sources. To complete this article, the author used an analysis method in the form of interviews. The research results from this article show that the disaster of crop failure did not occur because of God's hatred but rather as a form of care so that humanity turns to Him and lives in a movement of ecumenical love for others. Based on Kosuke Koyama's theory, it can be concluded that God's intention for the crop failure disaster that occurred in the Sa'dan Tiroallo area was as a form of invitation so that humans have concern in terms of love for their neighbours, as well as a form of warning so that people can spend time communing with God and to repent and turn to God.Pengenalan terhadap kasih dan pemeliharaan Allah tidak cukup dengan persekutuan, tetapi juga lewat bencana dalam hidup, salah satunya lewat gagal panen. Penelitian ini bertujuan untuk menemukan dan memahami bentuk pemeliharaan Allah lewat bencana gagal panen berdasarkan kehendak Allah yang hadir di tengah-tengah kehidupan manusia. Beberapa teori yang digunakan oleh penulis seperti teori bencana, teologi Kosuke Koyama, dan teori tentang Allah yang dirangkumkan dari beberapa penulis. Metode penelitian yang digunakan oleh penulis adalah metode kualitatif dengan pendekatan deskriptif. Kualitatif dikembangkan lewat studi kepustakaan yang bersumber dari literatur-literatur buku, artikel dan sumber internet yang relevan, untuk melengkapi tulisan tersebut, penulis menggunakan metode analisis dalam bentuk wawancara. Hasil penelitian dari tulisan tersebut adalah bahwa bencana gagal panen bukan terjadi karena kebencian Allah melainkan sebagai bentuk pemeliharaan supaya umat manusia berbalik kepada-Nya, dan hidup dalam gerakan kasih oikumene bagi sesama. Berdasar terhadap teori Kosuke Koyama maka disimpulkan bahwa maksud Allah terhadap bencana gagal panen yang terjadi di daerah Sa’dan Tiroallo adalah sebagai bentuk ajakan supaya manusia memiliki kepedulian dalam hal kasih kepada sesama mereka, juga sebagai bentuk teguran supaya umat dapat meluangkan waktu bersekutu bersama Allah serta untuk bertobat dan berbalik kepada Allah
