Authors: Desmi Adzuha
Published: August 2021

Retarder merupakan bahan kimia pembantu untuk memperlambat waktu pengikatan (setting time) sehingga campuran akan tetap mudah dikerjakan (workable) untuk waktu yang lebih lama. Penggunaan untuk menunda waktu pengikatan beton (setting time) misalnya dengan kondisi cuaca yang panas, atau memperpanjang waktu pemadatan untuk menghindari cold joint dan menghindari dampak penurunan saat beton segar pada saat pengecoran dilaksanakan. Penelitian ini bertujuan untuk mengetahui perubahan perilaku beton terhadap penambahan kadar gula pasir sebagai retarder, dan untuk mengetahui perbandingan sifat-sifat beton yang menggunakan gula pasir dan tanpa menggunakan gula pasir. Persentase penambahan kadar gula pasir 0,15%, 0,30% dan 0,45 % dari berat semen. Setiap variasi dan persentase kadar gula pasir di buat benda uji sebanyak 3 benda uji untuk pengujian tes Vicat, yaitu semen bila dicampur dengan air akan menghasilkan pasta yang plastis dan lecak. Namun setelah selang beberapa waktu, pasta akan mulai menjadi kaku dan sukar dikerjakan, inilah yang disebut pengikatan awal (initial set). Selanjutnya pasta akan meningkat kekuatannya sehingga didapatkan padatan yang utuh, ini disebut pengikatan akhir (final set). Proses berlanjut hingga pasta mempunyai kekuatan, disebut pengerasan (hardening). Hasil uji Vicat menunjukkan perlambatan pengerasan penundaan yang maksimum terjadi pada kadar gula pasir 0,45%, sedangkan pada kadar gula pasir 0,00% terjadi penundaan pengerasan secara normal. Jadi penambahan kadar gula pasir 0,15% sampai 0,45% dapat dianggap sebagai Retarder.

Kata Kunci : retarder, gula pasir, tes vicat, initial set, final set.

Published: August 2021

Lapisan podasi bawah konstruksi sebuah jalan merupakan salah satu faktor yang sangat berperan dalam menentukan kestabilan (kekuatan) dari kostruksi jalan. Besaran nilai daya dukung lapis pondasi bawah sangat dipengaruhi (ditentukan) oleh besar atau kecilnya nilai CBR dari lapis tersebut. Nilai daya dukung subbase didapat dengan menggunakan alat uji CBR. Sand cone digunakan untuk menguji kepadatan dari lapisan lapisan pondasi bawah. Metode yang digunakan adalah dengan cara melakukan pengujian langsung di lapangan untuk memperoleh nilai CBR lapangan. Sedangkan untuk memperoleh nilai sand cone dengan cara mengambil langsung material dari lapangan yang telah dipadatkan dengan menggunakan alat uji sand cone kemudian dilakukan pemeriksaan di laboratorium. Pelaksanaan pengujian mengikuti prosedur-prosedur pengujian sesuai standar yang berlaku baik yang dikeluarkan oleh bina marga maupun oleh AASTHO. Tujuan penelitian ini adalah ingin mengetahui hubungan (kolerasi) nilai CBR dan nilai Sand cone terhadap ketebalan lapisan pondasi bawah pada sebuah kontruksi jalan. Berdasarkan hasil tes CBR nilai yang didapat antara 60,27 % s.d 72,87 % sedang Sand Cone antara 59,88 % s.d 62,71 %. Setelah dirata-ratakan nilai CBR dan Sand Cone menjadi 62,48 % dan 60,44 %. Dari hasil pengujian korelasi Product Moment diperoleh nilai korelasi sebesar -0,225. Hal ini menunjukkan hubungan yang negatif antara nilai CBR dan Sand Cone. Selanjutnya dari hasil uji signifikansi koefisien korelasi diperoleh nilai t hitung = -0,730, nilai t hitung ini lebih kecil dari t tabel = 2,228 dengan derajat kebebasan 12 -2 = 10 dan taraf kesalahan 5 % untuk uji 2 pihak, jadi dapat disimpulkan Ho diterima dan H1 ditolak. Hal ini berarti tidak terdapat korelasi yang signifikan antara nilai CBR dan Sand Cone.

OPTIMASI SIMPANG BERSINYAL JALAN MERDEKA KOTA LHOKSEUMAWE
Authors: Mulizar Mulizar
Published: August 2021

Optimasi simpang bersinyal dimaksudkan untuk mengoptimalkan kinerja suatu jaringan jalan khususnya pada persimpangan bersinyal. Salah satu bentuk optimasi adalah melakukan sinkronisasi simpang bersinyal sehingga diperoleh suatu sistem koordinasi antar simpang bersinyal. Sistem ini bertujuan untuk mengurangi waktu tunda dan waktu berhenti kendaraan. Setelah melakukan antrian waktu merah pada salah satu persimpangan, kendaraan diharapkan akan memperoleh waktu hijau pada persimpangan berikutnya. Sistem demikian belum diterapkan di Jalan Merdeka Kota Lhokseumawe. Sebagai jalan utama pada pada lintasan tersebut ada tiga persimpangan bersinyal yaitu, Simpang BI (simpang I), Simpang Empat (simpang II) dan Simpang BPD (simpang III). Akibat belum adanya koordinasi antar ketiga persimpangan tersebut, sering kendaraan yang baru lolos dari simpang I harus berhenti dan menunggu fase hijau lagi pada simpang II dan sebaliknya. Hal yang sama juga terjadi antara simpang II dan simpang III sehingga antrian, waktu tundaan dan waktu berhenti yang panjang terutama pada jam puncak tidak dapat dihindari. Berdasarkan kondisi tersebut maka dilakukan studi untuk memperbaiki kinerja simpang tersebut dengan cara melakukan optimasi lampu lalulintas persimpangan. Ada dua metode yang digunakan pada optimasi ini, yaitu Manual Kapasitas Jalan Indonesia (MKJI 1997) untuk pengolahan data lalulintas, sementara untuk optimasi menggunakan bantuan perangkat lunak Transyt 14 berpedoman pada metode yang dikembangkan oleh TRRL (Transport and Road Research Laboratory) Inggris. Transyt 14 digunakan untuk mengevaluasi kinerja persimpangan pada kondisi eksisting dan sebagai alat bantu proses optimasi untuk koordinasi persimpangan dengan panjang antrian, waktu tunda, jumlah henti sebagai parameter utama. Hasil optimasi dibandingkan kondisi eksisting diperoleh waktu siklus 81 detik, antrian berkurang 14,15%, waktu tunda berkurang 44,60%, jumlah henti turun 36,23% dan tingkat pelayanan dapat ditingkatkan dari D menjadi C.

PENGARUH PENGGUNAAN ABU SERBUK KAYU TERHADAP KUAT TEKAN DAN DAYA SERAP AIR PADA PAVING BLOCK
Authors: Widari Lis Ayu
Published: August 2021

Paving block terdiri dari campuran semen, air dan agregat halus. Ketika semen dicampur dengan air maka proses hidrasi semen menghasilkan kalsium silikat hidrat (CSH), panas dan kalsium hidroksida (Ca(OH)2). Unsur Ca(OH)2 bersifat basa kuat sehingga menurunkan kuat tekan paving block. Unsur tersebut dapat direaksikan kembali dengan pozzoland untuk menghasilkan unsur CSH kembali. Namun dengan biaya yang relatif mahal, timbul inovasi baru untuk mengolah limbah yang memiliki unsur yang sama dengan pozzolan yaitu silika seperti limbah serbuk kayu. Limbah serbuk kayu merbau diolah dengan dibakar menggunakan furnace suhu 800°c. Abu yang dihasilkan diayak dengan menggunakan saringan no 200. Benda uji dicetak menggunakan mesin press vibrasi dengan variasi penambahan 10%, 15%, 20%, dan 25% dan direndam selama 28 hari. Kuat tekan rata-rata yang dihasilkan pervariasinya adalah 11,979 Mpa, 13,281 Mpa, 14,792 Mpa dan 13,594 Mpa. Dengan daya serap air 4,345%, 3,529%, 2,555% dan 3,063%. Paving block dengan penambahan abu serbuk kayu mengalami penurunan kuat tekan dari paving block normal yaitu 17,760 Mpa. Paving block tersebut termasuk katagori mutu C, bisa digunakan untuk pejalan kaki. Sehingga perlu dilakukannya penelitian lanjutan untuk variasi penambahan dan jenis kayu lainnya untuk mendapatkan paving block dengan mutu yang lebih baik.

Kata Kunci : abu serbuk kayu, kuat tekan, daya serap air, dan paving block.

Global warming is a natural phenomenon that is currently taking place. Natural phenomena occur as a result of changing ecosystem balance. This can be minimized by adding vegetation which acts as an absorber of CO2 to convert CO2 into glucose and oxygen through the process of photosynthesis. Each type of vegetation has the potential to absorb different carbon, so this can be circumvented by using the right cropping pattern. Therefore, information about the potential for carbon stored in complex and simple agroforestry cropping patterns in KPH Batutegi is important. The purpose of this study was to analyze carbon stocks in agroforestry cropping patterns and to compare carbon stocks in simple and complex agroforestry cropping patterns in KPH Batutegi. Source of living tree biomass, dead tree biomass, understorey biomass, and litter biomass.

This article uses an esoteric approach in explaining the intersection of religions in the Yudaeo tradition. There is a misunderstanding of religion because it is seen from an exoteric approach. As a result, people tend to judge that this religion is right and another is wrong. Whereas Abraham is known as the father of monotheistic religions, namely Judaism, Christianity and Islam. The vision of the Judaeo-Christian-Islamic tradition is an indicator of the three religions as monotheistic religions whose teachings are inseparable and cannot be polarized between one another. However, for certain circles, Islam and Christianity are not seen as Yudaeo traditions, because they see the root of the problem that often causes conflicts between Islam and Christianity, especially in the position or capacity of the Koran as Muhaimin. The conflicts that often occur between the two religions often cause discomfort in theological encounters. This resulted in the relationship between the two religions experiencing unfounded "theological" tensions. Even though it is seen in the Yudaeo tradition of Islam-Christianity as a mission religion that descends from God Almighty. where both religions have theological continuity from the aspects of Divinity, Prophethood (prophecy), and revelation. This tradition should be built on the awareness of religiosity between the two adherents of religion (Islam-Christian) who have the same theological roots.

This research examines Hasan Langgulung 's perspective of Fitrah in Islamic education. This research is intended to analyze Hasan Langgulung 's essence of Islamic education and analyze the growth of Fitrah potentials from Hasan Langgulung 's perspective on Islamic Education. This research is a research library utilizing content analysis.

The results of the research revealed that 1) According to Hasan Langgulung, Fitrah is the original power buried in humans from birth, which will become a driving force and determinant of personality and service tools. 2) The potential of Fitrah in Islamic education from Hasan Langgulung 's perspective is an interaction between potential and culture, the possibility of religion that complements humans from birth, promoting the establishment of Islamic civilization. 3) The capacity of Fitrah and Gharizah requires humans to continually learn from their surroundings and the ability to think and choose (good and bad) to decide their course of life. This research shows that improving Fitrah 's potential can be an Islamic education model that can see students' different potential paths. It may also establish formal and informal education. The growth of the capacity of Fitrah by students, teachers, and parents, therefore, seeks to instill good behavior because nature does not evolve by itself. The principle of Fitrah also demands that Islamic education strive to guide instruction for a healthy human connection with God.

This paper is actually the author's desire to contribute to the idea of ​​halal thought initiated by most of the world's Muslims, the author does not interpret halal simply and narrowly but the author tries to interpret halal by changing the paradigm of Muslims that halal must be expanded into a halal industry. in this world. This paper inspires especially Muslims in Indonesia to have the courage to create new halal industries, developed in various aspects of the needs of the wider community. In this paper the author shows how great the potential of the halal industry is, but it must be driven by politics and productive market mechanisms. According to the author's research, the halal industry is actually a religious commandment, namely Islam, but more importantly the substance of the halal industry is to develop the desire and logic of consumption, why because the halal industry will progress and develop depending on the consumer who consumes goods, if the desire and logic of consumption is weak , then as good and as productive as any halal industry will not develop and experience progress, therefore the desire and logic of consumption is very important to be understood by Muslim entrepreneurs who will develop the halal industry.
REAL TIME POLYMERASE CHAIN REACTION (RT-PCR) FOR DNA PIG CONTAMINATION IDENTIFICATION SAUSAGE IN SIX DISTRICT PANDEGLANG BANTEN
Authors: Susilo Hadi
Published: August 2021

Sausage is a meat product processed that is popular food especially in Pandeglang, Banten Province. The importance of halal certificates or the existence of the MUI (Indonesian Ulama Council) halal logo for processed meat products makes Muslim people confident to consume them. The aim this research was to identify pig DNA contamination in sausage products in six  districts in Pandeglang without the MUI halal labels using RT-PCR (Real Time-Polymerase Chain Reaction). RT PCR that can calculate to pig to fill these sample free from pig contamination. This research was divided into two stage, the first stage is extracted or carried out DNA and the second stage is RT PCR analysis. The results of the DNA purity test on sausage samples had DNA purity values ​​of 1.84-1.9 (A260 / A280) and resulted in sample concentrations ranging from 37.8 to 102.5 ng / µl.  The only amplification on the FAM curve was in the positive control pig.  the Cq value ranges from 30 - 31.29. The results of RT PCR on sausage samples in the district area in Pandeglang Banten did not detect the presence of pig DNA.

The samples of humic preparations (HPs) containing macro and trace elements for plant nutrition were obtained based on humic acids isolated from brown coal of the Tisul deposit in the Kansk-Achinsk Coal Basin. The biological activity of the humic preparations was tested under laboratory and field conditions with the use of Iren and Novosibirskaya 89 varietal wheat seeds. A comparative assessment of the effects of the concentrations of various elements in the HPs on the growth parameters and productivity of cereals was carried out. The edaphic properties of soil substrates should be taken into account for a more effective use of humic preparations.

The goal was to study the effect of certain types of mineral fertilizers (N, P, K) and their paired compounds (NP, NK, PK) on the protein and gluten content in the grain of winter wheat on chernozem typical (Haplic Chernozem (Profundihumic)). The research was carried out in the conditions of a field stationary experiment which was laid down in the experimental farm of the NSC "Institute for Soil Science and Agrochemistry Research named after O. N. Sokolovsky" in the Kharkiv region. Eight variants with the following norms of fertilizers were studied for winter wheat: 1 – without fertilizers (control); 2 – N60; 3 – P120; 4 – K90; 5 – N60P120; 6 – N60K90; 7 – P120K90; 8 – N60P120K90. The effectiveness of fertilizers was reseached on two agrophones - natural and aftereffect of fertilizers (240 t/ha for crop rotation). The content of protein and gluten in wheat grain was determined on the Spectran-119M. On typical chernozem of the Forest-Steppe of the left-bank high application of nitrogen and phosphorus fertilizers in norm N60P120 provides the content of protein in grain of winter wheat at the level of 12,9 – 14,7 % that corresponds to the 1st and 2nd classes of quality of grain according to the National standard (DSTU 3768 : 2010). The gluten content ranges from 23.6 to 25.0 %, which corresponds to the 2nd class of grain quality of winter wheat.

Treating COVID-19 with Anticoagulation based on Kabir Bleeding Risk Score
Authors: Kabir Azad A
Published: August 2021

Three large randomized clinical trials named the ATTACC, ACTIV-4a, and REMAP-CAP were terminated early as these trials showed use of therapeutic anticoagulation among non-critical COVID-19 patients increased the probability of survival to hospital discharge as well as reduced the need for cardiovascular or respiratory organ support. These clinical trials also showed when a COVID-19 patient presents with a critical stage, therapeutic anticoagulation does not provide any benefit. This study retrospectively evaluated the COVID-19 admission at Jackson Hospital, Alabama, USA from June 15th, 2020, to June 15th, 2021. The study developed COVID-19 mechanism of death and found that anticoagulation doses can be titrated up or down based on D-Dimer trends and many patients do not need therapeutic anticoagulation, rather an intermediate dose (Lovenox 0.5mg/kg subQ BID or higher dose) anticoagulation can be sufficient for those who have a higher risk of bleeding. The author developed the Kabir bleeding risk score-based treatment strategies for COVID-19 patients which can be visited by clicking on the following link: .
Norm vigilance in reaction to control threat: A file drawer report
Authors: Czepluch Felix , Jugert Philipp , Fritsche Immo
Published: August 2021

In times of threat people often turn to social groups to fulfill various needs. In situations where this threat is related to people’s personal sense of control, the model of group-based control provides a social-identity-based account of why thinking and acting in terms of group membership should become more likely to occur. We set out to extend this perspective to the perception and processing of information about norms. Our initial hypothesis, the norm vigilance hypothesis, was that threat to people’s personal sense of control should induce a state where people become more vigilant for information about relevant social norms. This should become evident in more accurate recall of specifically this type of information under conditions of threat. In a series of four studies, we investigated this hypothesis with different paradigms, but were unable to find convincing evidence for the notion of norm vigilance in terms of enhanced accuracy. In a fifth study, we investigated an alternative hypothesis of motivated intergroup distortion of information about social norms after threat, but did not find convincing evidence for this mechanism either.
When numbers fail: Do researchers agree on operationalisation of published research?
Authors: Haucke Matthias , Hoekstra Rink , van Ravenzwaaij Don
Published: August 2021

Current discussions on improving the reproducibility of science often revolve around statistical innovations. However, equally important for improving methodological rigour is a valid operationalisation of phenomena. Operationalisation is the process of translating theoretical constructs into measurable lab-quantities. Thus, the validity of operationalisation is central for the quality of empirical studies. But do differences in the validity of operationalisation affect the way scientists evaluate scientific literature? To investigate this, we adapted three published studies and manipulated the strength of operationalisation. We preregistered our planned study as a registered report. For each study, we designed two tasks in which the validity of the used operationalisation is manipulated and sent them to researchers via email. In the first task, researchers were presented with a summary of the Method and Result section from one of the studies and were asked to guess the hypothesis that was investigated via a multiple-choice questionnaire. In a second task, researchers were asked to rate the perceived quality of the study. Our results show that (1) researchers are better at inferring the underlying research question from empirical results if the operationalisation is more valid; but (2) the different validity is only to some extent reflected in a different judgment of the quality of the study. These results combined give partial evidence for the notion that researchers’ evaluations of research results are not affected by operationalisation validity.

Authors: Rai Arjun
Published: August 2021

This survey examined the association between the gender of the respondents and their desire to join or form a local cooperative association, perception towards the quality of locally grown agricultural products, and practice of selling locally produced agricultural products of the residents of Musunkhel, ward number 3 of Laligurans Municipality of Tehrathum district, Province No.1, Nepal. The population in the study comprised all the households of ward number 3 of Laligurans Municipality. This survey used a standardized questionnaire to collect primary data from 92 households from the targeted area. However, this study included 79 households only. The remaining households were filtered during the data curation and cleaning process. The collected data were processed in the Statistical Package for the Social Science (SPSS), version 25. Data were analyzed using descriptive and inferential statistical tools. The study's findings indicated an insignificant association between gender and desire to join or form a local cooperative association, perception towards the quality of locally grown agricultural products, and practice of selling locally produced agricultural products. The study also found that the level of qualification does not influence awareness of the export process. However, relatively respondents with lower academic qualifications were aware of the export procedure.
