Abstract

Access to clean water is essential for human life and a key target of Sustainable Development Goal (SDG) 6: Clean Water and Sanitation. However, cities in developing countries, including Padang City, Indonesia, face significant challenges in meeting the growing demand due to population growth and limited water infrastructure. This study used system dynamics modelling approach with Powersim Studio 10 to develop an integrated clean water management system for Padang City. The model simulates the dynamics of population growth, water consumption, production, and distribution efficiency over a 20-year period (2022–2042). Several policy scenarios—optimistic, moderate, and pessimistic—were tested to evaluate their impact on water availability. The baseline scenario predicts a continuous decline in clean water supply due to increasing population, high leakage rates (11.99%), and water wastage (2%), which surpass the water production growth rate (5.01%). As a result, a water deficit is expected. However, under the optimistic scenario, with increased production (10%), reduced leakage (8%), and reduced wastage (3%), Padang City could achieve a clean water surplus by 2042. The moderate and pessimistic scenarios still result in a deficit. This research highlights the value of the system dynamics modelling in forecasting urban water demand and assessing policy impacts. The findings emphasize the need for integrated planning, combining technical solutions and behavioural change, to ensure sustainable water management and support the achievement of SDG 6.

Abstract

Drinking water is a very important basic need for humans. One of the detected drinking water pollution that greatly affects the quality is the content of nanoplastics. In aquatic ecosystems, nanoplastics are materials that cannot be decomposed. Through this brief review, the efficiency of removing nanoplastics using various water treatment methods will be reviewed. Some of the treatment methods reviewed are nanoplastic removal using filtration, adsorption, coagulant and flocculant addition, and CFS (Coagulation/Flocculation Sedimentation). The research method used is a literature review related to drinking water treatment to eliminate pollution by nanoplastics. The conclusion from the literature review is that the process of treating drinking water by filtration with the addition of coagulants is the most efficient treatment for removing pollution by nanoplastics, reaching 99.9%.

Abstract

Air pollution is one of the most dangerous and worrying. One of the causes of air pollution is dust or Total Suspended Particulate (TSP), namely particles with a diameter of <100 μm. The Total Suspended Particulate causes visual distrurbances and respiratory disorders such as URTI (Upper Respiratory Tract Infection). According to data from Badan Pusat Statistik Kota Padang in 2018, URTI represents the highest complaint in the district Lubuk Begalung as many as 5,534 cases (28%). In the district has industrial and transportation activities which are a source of air pollution. However, in there haven’t real time monitoring of air pollution, so it is necessary to carry out air pollution simulations. This study aims to determine the concentration of TSP ambient air pollution and to analyze the distribution air pollutant in the Lubuk Begalung District, Padang City. The research method used a quantitative, where the emission inventory and meteorological data used the Gauss dispersion model and surver 15 software. The maximum TSP from measurement and modeling results was 113.42 µg/m3 and 27.16 µg/m3. This result explain about the TSP concentration is still below the National BMUA in PP RI No. 41 of 1999, which is 230 µg/m3 (still in good condition). This is different from previous studies because this study only considers sources of industrial emissions without other sources of pollution. The result of the TSP distribution is moving increasingly towards the Southwest from the emission source and reaches a maximum concentration at the coordinate point (-0.98103 oS, 100.34567 oE), according to the dominant wind direction.

Abstract

Islamic Religious Education and moral education play a strategic role as key pillars in shaping the character of elementary school students to face increasingly complex contemporary challenges. Both function not merely as a transmission of normative knowledge, but also as essential instruments for instilling fundamental values such as honesty, responsibility, and empathy in everyday life. Through a literature-based study reviewing various academic journals and scholarly references, this study finds that the integration of religious and moral education within the formal education system constitutes a crucial foundation for students’ character development. The analysis indicates that strengthening these two aspects in an integrated manner has a significant impact, particularly on improving students’ moral conduct, discipline, and awareness of social responsibility. Therefore, strong synergy is required among educational institutions, the role of teachers as role models, and the family environment as the primary foundation to ensure that moral and spiritual values are optimally internalized in the educational process. Thus, this article emphasizes that Islamic religious and moral education in elementary schools plays an important role in shaping a young generation that is religious, possesses noble character, and is ready to become a pillar of the nation by contributing positively to society and the wider world.

Abstract

Hadis Nabi merupakan salah satu dari dua sumber Islam yang memiliki peranan yang sangat penting dalam kokohnya bangunan Islam. Mengetahui asbab al-wurud dalam ilmu hadis sama pentingnya dalam mengetahui asbab an-nuzul dalam al-Qur’an, yang mana keduanya sama-sama menjadi ruh kontekstual dari sebuah peristiwa. Asbab al-wurud menjadi kajian yang sangat penting dalam pembahasan hadis, dikarenakan agar tidak terjadi kesalah pahaman dalam menangkap maksud dari suatu hadis. Pemahaman yang mengabaikan asbab al-wurud suatu hadis, lebih cenderung terjebak pada arti tekstualnya saja bahkan dapat membawa pemahaman yang keliru. Memahami teks suatu hadis tidak terlepas dari analisis mendalam terhadap konteksnya. Kedua hal tersebut tidak dapat dipisahkan karena konteks telah memproduksi teks. Oleh karena itu kajian asbab al-wurud ini merupakan cara yang paling baik untuk memahami makna hadis dengan tepat dan benar. Dalam kajian ini juga dipaparkan pentingnya mengetahui asbab al-wurud, cara mengetahui asbab al-wurud, dan klasifikasi asbab al-wurud yang terdiri atas ayat Al-Qur’an, hadis, sebab yang berupa perkara yang berkaitan dengan para sahabat yang mendengar hadis tersebut dan pentingnya asbabul wurud dalam pendidikan.
