Abstract

This study aims to determine the magnitude of the decline in clay, by comparing the reduction in soft clay soil of the village Belimbing Sari and organic clay from the village of Beteng Sari, using concrete reinforcement mats and bamboo poles to increase the carrying capacity of the land, because the clay when getting the imposition of the will experience a significant drop. This research was conducted by making test Boks modeling land subsidence, and perform impairment testing ground that has been given concrete reinforcement using a bamboo mat with a pole on soft clay soil of the village Belimbing Sari and organic clay from the village of Beteng Sari. Using weights ranging from 0.2 kg/cm2, 0.3 kg/cm2, 0.4 kg/cm2, 0.5 kg/cm2. Testing was conducted on the impairment testing ground to seek consolidation coefficient (Cv), congestion coefficient of volume (Mv), compression index (Cc) and coefficient of compression (Av). Based on the research results, the test box, the decline in clay is lower than the original soil testing, this happens because the test soil reinforcement box has been given a concrete form bamboo mat with a pole. From this it can be concluded that the carrying capacity of the clay to get better after being given reinforcement.

Abstract

Paving block is made of by mixturing cement portland or other hidrolic material, water, and agre- gate or without any other material. In this research paving blok will be made by using of soil, ce- ment, and rice husk ash. Besides, soaking of paving block is aimed to improve compressive the paving block that is suitable with SNI 03-0691 (1996). The samples of soil that is used came fromq ITERA, South Lampung. The making of paving block samples consists of two stages. First, mixture A (10% of cement, 5% of rice husk ash, 85% of silt soil) and mixture B (15% of cement, 5% of rice husk ash, 80% of silt soil) and the making of samples in the second stage is to deter- mine the effect of immersion of compressive the paving block in which the samples using is sam - ples with optimum compressive result from making samples in the firsh strage by time variant in 0 day, 7 days, 14 days, 21 days and 28 days and also by doing pre-burning and post-burning. From the experiment result of innovation compressive this paving block includes to the quality class D and absorption of paving block that is made of mixturing soil, cement, and rice husk ash is not ap- propriate with SNI 03-0691 (1996). The adding of rice husk ash gives a little influence in improv- ing compressive of paving block. The soaking that is done to paving block causing the decrease of compressive till 45,7%. The highes compressive produced by paving block post-burning during immersion 0 day that is 11,70 Mpa.

Abstract

This paper reports on an international collaboration between two universities, one private university in Indonesia (Universitas Muhammadiyah Jakarta, UMJ) and one public and world class university in Malaysia (Universiti Teknologi Malaysia, UTM). Both collaborative action plans were implemented through projects in program development, faculty exchange, graduate student/teacher field experiences, pre-service student’s internship mentoring and also conjoined research in the area of a foreign/second language teaching and teacher development, and educational technology. Over a three-year period from 2015-2018 reported that UMJ, i.e Fakultas Ilmu Pendidikan (Faculty of Education) sent students for teaching practice to Fakulti Pendidikan UTM in four batches with 65 preservice students. In March 2018, UTM sent seven students to do internship program atUMJ. This collaboration commitment portrayed a smooth international partnership between universities and hoped to be continued in other field of collaborations. Keywords: international collaboration, teaching practice program, UTM, UMJ

Abstract

Salah satu upaya untuk menciptakan inovasi baru pada bahan campuran paving block yaitu dengan material tanah ditambah bahan aditif semen atau kapur disubtitusi tambahan bahan additive fly ash (abu terbang) yang berasal dari limbah pembakaran batubara PLTU Tarahan Lampung dan membandingkan kuat tekan paving block dicampur semen fly ash dengan paving block dicampur kapur fly ash tanpa pembakaran. Sampel tanah yang diuji pada penelitian ini yaitu tanah yang berasal dari daerah Karang Anyar, Lampung Selatan. Variasi kadar campuran yang digunakan adalah 6%, 8% dan 10%, perbandingan antara fly ash ( abu terbang) dan semen yaitu 1:1 begitu pula fly ash dan kapur. Nilai kuat tekan paving block tanah dengan aditif semen dicampur fly ash lebih tinggi dibandingkan dengan penggunaan aditif kapur di tambah fly ash,. Nilai rata-rata kuat tekan yang dihasilkan secara keseluruhan campuran memenuhi syarat paving block SNI-03-0691-1996 yaitu minimal kuat tekan sebesar 85 kg/cm². Nilai kuat tekan yang memenuhi kuat tekan mutu paving block untuk jalan dengan menggunakan campuran semen ditambah fly ash pasca bakar dengan presentasi campuran 10%, Selain kuat tekan pengujian daya serap air yang dihasilkan diantara 3-9% secara keseluruhan memenuhi syaratpaving block SNI-03-0691-1996

Abstract

Perilaku amoral terus melaju ibarat anak panah yang melesat dari busurnya, seolah tak terbendung bisa menancap kepada siapa saja, tak terkecuali anak-anak yang masih usia remaja. Pendidikan karakter dan keteladanan di pondok pesantren salah satu benteng pertahanan yang paling kokoh hingga saat ini. Penelitian menemukan bahwa pendidikan karakter dan keteladanan sudah melekat, identik, dan teruji ratusan tahun-cenennial-di beberapa pondok pesantren besar termasuk pondok modern Darussalam Gontor yang diorkestrai oleh KH Imam Zarkasi. Di mana ruh karakter dan keteladanan beliau masih terus hidup hingga kini. Spirit pendidikan karakter dan keteladanan banyak terinspirasi daru dua tokoh protagonis di dalam Al-Qur’an yang disematkan kepada keduanya term “uswatun hasanah” yaitu habibullah Muhammad ﷺ dan khalilullah Ibrahim ‘alahissalam. Ujian dan cobaan yang dirasakan oleh kedua nabi protagonis dalam berdakwah juga dirasakan pahit-getirnya oleh KH Imam Zarkasyi yang melewati masa penjajahan Jepang, pemberontakan G-30 SPKI, dan gagasannya untuk menjadikan pendidikan pesantren sebagai pendidikan utama di Indonesia tidak diakomodir pemerintah saat itu.

Abstract

Easy access to distributed generation (DG) technology is promoting the utilization of single-phase DGs for residential purposes. Surplus energy generated by household DGs can be shared or sold to other communities through existing networks. However, the interconnection of single-phase DGs from residential generators to the distribution network requires careful handling to secure the reliability and quality of the electric power system. This paper focuses on the optimal placement of single-phase multi-type DGs on unbalanced distribution systems that are connected to nonlinear loads. The objective of this study is to minimize the power losses and voltage unbalances in the distribution networks. To verify the efficacy of this method in reducing voltage unbalances and harmonics, an optimization approach is also presented using three-phase DG. Optimal placement of DG is performed on a modified Kaliasin distribution system using an adaptive real coded genetic algorithm (ARC-GA). Simulation results demonstrate that the installation of single-phase DGs is highly effective in reducing power losses and voltage unbalances in the distribution networks.

Abstract

This research examines the dynamics of social interaction between ethnic groups and the influence of cultural values ​​on the formation of attitudes of tolerance and good citizenship among students in a multicultural school environment. Using a qualitative approach, this study involved observations, in-depth interviews, and document analysis to collect data from students and teachers in several ethnically diverse schools. The research results show that positive social interactions between students of various ethnicities promote understanding and appreciation of each other's cultural values, which is an important foundation in building tolerance. Furthermore, curricular and extracurricular activities designed to celebrate diversity are important instruments in developing students' citizenship. However, research also reveals barriers, such as prejudice and stereotypes, that need to be overcome through effective pedagogical approaches. Recommendations include developing inclusive learning programs, training teachers to manage diversity in the classroom, and integrating best practices between schools. This research provides insight into the importance of multicultural education in creating a harmonious society in the context of rich ethnic diversity.
