Tinjauan Dampak Metode Penginjilan Evangelism Explosion Bagi Pertumbuhan Jemaat Lokal

The Great Commission of the Lord Jesus commanded every believer to go make all nations. This is an important mandate called an evangelistic mandate. But there is no denying that many of God's churches or believers are not serious about carrying out the mandate of evangelism which is God's desire to bring believers to Him. The author tries to contribute to the understanding of one of the methods in evangelism, evangelism explosion method as an evangelistic method is quite effective for the growth of the local church. In obtaining accurate and accountable data, the author uses descriptive writing methods of literature. The purpose of this writing is to convey how important evangelism is in the local congregation. Then through evangelism the evangelism explosion method became a very effective method of bringing people to accept Jesus as Lord, and the Savior personally. In addition, local congregations can play an active role in evangelism. The impact of the application of this method experienced the maximum growth of the congregation and evangelism into the lifestyle of believers.Keyword : Evangelism Explosion, Local Church AbstrakAmanat Agung Tuhan Yesus memerintahkan setiap orang percaya untuk pergi menjadikan semua bangsa. Ini merupakan mandat penting yang disebut mandat penginjilan. Namun tidak bisa dipungkiri, banyak gereja Tuhan atau orang percaya tidak serius dalam melaksanakan mandat penginjilan yang merupakan keinginan Tuhan untuk membawa orang percaya kepada-Nya. Penulis mencoba memberikan kontribusi pemahaman salah satu metode dalam penginjilan, yaitu metode evangelism explosion sebagai metode penginjilan cukup efektif bagi pertumbuhan gereja lokal. Di dalam mendapatkan data-data yang akurat dan dapat dipertanggungjawabkan, penulis menggunakan metode penulisan deskriptif literatur. Tujuan penulisan ini adalah menyampaikan betapa pentingnya sebuah penginjilan dalam jemaat lokal. Kemudian melalui metode penginjilan dengan evangelism explosion menjadi metode yang sangat efektif dalam membawa orang menerima Yesus sebagai Tuhan, dan Juruselamat secara pribadi. Selain itu jemaat lokal dapat berperan aktif dalam penginjilan. Dampak dari penerapan metode ini mengalami pertumbuhan jemaat yang maksimal dan penginjilan menjadi gaya hidup orang percaya.Kata Kunci : Evangelism Explosion, Gereja Lokal

Controlled Cracking of Large Size Concrete Structures by a Steam Pressure Cracking Agent

The dismantling of large concrete structures causes environmental pollution due to the dispersion of polluted micro-particles. The purpose of this study is to develop an environmentally friendly demolition method. Steam pressure cracking (SPC) is a method that can safely and quickly separate concrete because there is less vibration compared to the explosion method. To date, the authors have shown that the direction of cracking in a small sample can be controlled by an induction hole. The principle of control is that the elastic wave of compression stress generated from the SPC reaction changes to a tensile elastic wave at the induction hole, and a crack is initiated. In this study, it was shown that the direction of crack propagation can be controlled by using induction holes in large concrete structures that are 1m on each side. Further, in the SPC method, the large amount of concrete powder generated by the explosion method is not produced, and there is no risk of secondary contamination by fine concrete powder. It was also possible to separate small pieces from the end face of the large concrete by SPC and induction holes. The area over which the crack propagated depends on the energy generated from the SPC agent, and the relationship was linear. By applying an SPC agent to dismantling large concrete structures, we can achieve controlled cracking safely and quickly without any environmental pollution.

An economically sustainable bifunctional Ni@C catalyst in a solar-to-hydrogen device employing a CIGS submodule

In this work, Ni@C was successfully fabricated using a one-step metal wire explosion method and employed as a bifunctional catalyst material for electrodes in an electrolyzer connected to a CIGS-sub module for continuous hydrogen production.

Preparation and characterisation of electrospun composite nanofibre polyvinyl alcohol/ nanofibrillated cellulose isolated from oil palm empty fruit bunches

Composite nanofibre polyvinyl alcohol (PVOH) was prepared in this work reinforced with nanofibrillated cellulose (NFC) using an electrospinning technique. NFC was isolated from oil palm empty fruit bunches (OPEFB) by steam explosion method followed by acid hydrolysis. A 12 wt% PVOH solution in distilled water was prepared under constant reflux at 80 ºC for 5 h. Several concentrations of NFC were added to the polymer solution of 2.5, 5.0, and 7.5 wt%. The nano-dimension of NFC was analysed using transmission electron microscopy (TEM). The morphology of electrospun nanofibre was characterised using scanning electron microscopy (SEM). The morphology of PVOH nanofibre was smooth and uniform without beads. The presence of NFC in the PVOH nanofibre decreased the diameter. The morphology of PVOH/NFC nanofibre at a concentration of NFC 2.5% was fairly uniform with good quality. However, the preparation of PVOH/NFC nanofibre at concentrations of NFC 5.0% and 7.5% resulted in elliptical beads. The crystallinity of NFC and electrospinning nanofibre was investigated using X-ray diffraction (XRD). In addition, the thermal properties of the samples were analysed using thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The results showed that NFC improved the thermal stability of electrospun PVOH nanofibre.

Particularities regarding the evaluation of large equipment for explosive atmospheres

For placing electrical equipment that is protected by pressurized casings type of protection on the European market and for its use in spaces classified as explosive atmospheres, they must be evaluated and tested in accordance to relevant standards. The paper aims at presenting the peculiarities regarding the evaluation of large-scale equipment for explosive atmospheres. The first part of the paper refers to general requirements for large electrical equipment intended for use in explosive atmospheres. The requirements of pressurized casings type of protection and its technical principle of protection are shown in Part Two. As a conclusion, it has been pointed out that the disadvantage of energy consumed to provide protection to explosion provides the benefit of protection to explosion for large or complex structure equipment for which no other protection to explosion method can be applied.
