Abstract

This study examines the implementation of the principle of qaulan layyina as mentioned in the Qur’an (QS. Taha: 44) within the context of Islamic preaching on Indonesian television, specifically in the Q&A program aired on Metro TV. Utilizing a descriptive qualitative approach supported by literature analysis, this research explores how preachers deliver religious messages with gentleness, empathy, and persuasion to a heterogeneous audience. The study highlights that the application of qaulan layyina is influenced by several factors, including the preacher’s personal understanding of Islamic ethical principles, their communication skills, and the structure of the television program. The findings demonstrate that most preachers succeed in maintaining a soft and inclusive tone, especially when responding to sensitive or controversial questions. Through this approach, they are able to minimize conflict, promote mutual respect, and uphold the core values of Islamic communication. This research contributes to the broader field of Islamic communication studies and offers practical insights for da’wah practices in modern media environments. Keywords: Qaulan Layyina, Da’wah, Q&A Di Metro TV.

Abstract

The most obvious characteristics of lignite are its high moisture content (30-50%) and relatively low calorific value compared to other types of coal. This causes low combustion efficiency, making it not optimal for use as fuel. In this study, the slurry dewatering process was applied to coal that has a low calorific value of 3,662 cal/g and a moisture content of 37.29%. The addition effect of heavy oil from catalytic cracking of Polypropylene-Low Density Polyethylene (PP/LDPE) plastic waste pyrolysis oil on improving quality of lignite was investigated in this study. Heavy oil was used as additive. The ratio of 120 mesh lignite to heavy oil used was 100:15, 100:30, 100:45, 100:60, 100:75, and 100:90 (g/mL). Coal was carried out with a slurry dewatering process in an autoclave at various temperatures of 140 and 150 °C for 60 min. The test results obtained the highest calorific value of 6,374 cal/g and the moisture content of 2.81% for a ratio of lignite to heavy oil of 100: 45 g/mL at a temperature of 140 °C.

Abstract

Latar Belakang: Desa Bulu Cindea, Kabupaten Pangkep, merupakan salah satu penghasil garam terbesar di Sulawesi Selatan. Namun, masyarakat setempat hanya memproduksi garam mentah dengan nilai ekonomi rendah, yang menyebabkan keterbatasan dalam peningkatan kesejahteraan ekonomi mereka. Program pengabdian masyarakat ini bertujuan untuk meningkatkan keterampilan masyarakat dalam diversifikasi produk berbasis garam menjadi garam spa BC dan garam susu BC, yang memiliki nilai tambah lebih tinggi. Metode: Metode yang digunakan meliputi penyuluhan, pelatihan berbasis praktik langsung, dan pendampingan berkelanjutan dalam pengolahan garam dengan memanfaatkan bahan lokal, termasuk limbah garam berkandungan magnesium tinggi. Keberhasilan program diukur berdasarkan peningkatan keterampilan peserta, jumlah produk yang berhasil diproduksi, serta peningkatan pendapatan masyarakat dari hasil penjualan produk diversifikasi garam. Hasil: Menunjukkan bahwa 85% peserta memahami dan mampu menerapkan proses pembuatan garam spa dan garam susu, serta menghasilkan produk dengan kualitas yang memenuhi standar pasar. Selain itu, terjadi peningkatan rata-rata pendapatan peserta sebesar 30% setelah program berjalan selama enam bulan. Program ini berdampak positif terhadap keterampilan masyarakat, terutama ibu rumah tangga, serta membuka peluang ekonomi baru yang berkelanjutan. Kesimpulan: Novelty dari program ini terletak pada pemanfaatan limbah garam berkandungan magnesium tinggi sebagai bahan baku utama dalam produk garam spa dan garam susu, yang sebelumnya kurang dimanfaatkan. Selain itu, pendekatan pelatihan berbasis komunitas dengan pendampingan jangka panjang memastikan keberlanjutan usaha serta peningkatan daya saing produk di pasar lokal maupun nasional. Untuk keberhasilan jangka panjang, direkomendasikan adanya pendampingan lebih lanjut dalam aspek pengemasan dan strategi pemasaran digital guna memperluas akses pasar serta meningkatkan daya saing produk di tingkat nasional dan internasional.

Abstract

Salah satu metode desalinasi adalah capacitive deionization (CDI). CDI terdiri dari elektroda arang aktif, dan untuk meningkatkan kinerjanya perlu adanya lapisan penukar ion pada permukaan elektroda. Salah satu bahan alam yang dapat digunakan sebagai adsorben penukar ion adalah silika. Penelitian ini untuk mengetahui efek ketebalan silika sebagai material penukar ion pada elektroda CDI terhadap kapasitansi dan kemampuan desalinasi air laut. Elektroda arang aktif terbuat dari cangkang kemiri kemudian penukar ion dibuat dengan mencampur 9 gr silika, 1 gr Polyvinyl Alcohol (PVA) lalu dilarutkan dalam 15 ml alkohol dan diaduk menggunakan magnetic stirrer sampai membentuk bubur, lalu dicetak dengan ukuran 30 mm × 30 mm ketebalan 1 mm, 2 mm, dan 3 mm di atas elektroda arang aktif ketebalan 10 mm lalu dikeringkan dengan oven pada temperatur 70°C selama ± 1 jam. Proses Kapasitansi ditentukan dengan rangkaian RC (Resistor Capasitor) yang dihubungkan dengan osiloskop serta proses desalinasi menggunakan metode  CDI yang tersusun dari sepasang elektroda, dua buah kolektor, dan satu buah separator yang diberi beda potensial sebesar 1,5 V. Pengukuran salinitas menggunakan Handrefractometer dan konduktivitas menggunakan Conductivity  meter.  Ketebalan  penukar  ion  1  mm,  2  mm,  dan  3  mm memiliki hasil nilai kapasitansi masing-masing diperoleh sebesar 6,928 10-10 F, 6,318  10-10 F, dan 5,417  10-10 F. Untuk hasil salinitas diperoleh sebesar 6 ‰, 6 ‰, dan 10 ‰ dan untuk hasil konduktivitas diperoleh sebesar 2,49 mS/cm, 2,58 mS/cm, dan 6, 32 mS/cm. Hasil penelitian menunjukkan bahwa dengan menggunakan penukar ion yang lebih tipis mengalami kenaikkan nilai kapasitansi, penurunan salinitas dan konduktivitas tertinggi dibandingkan dengan ketebalan penukar ion yang lain. Efek variasi ketebalan mempengaruhi tinggi rendahnya nilai kapasitansi kemudian  hasil  salinitas  mencapai 6 ‰ untuk ketebalan 1 mm dan 2 mm dan nilai konduktivitas 2,49 mS/cm untuk ketebalan 1 mm. Hal ini menunjukkan bahwa air yang dihasilkan masih dalam kategori air payau.

Abstract

The objective of this study was to analyze the dynamics of spread and tissue damage due to infection with Black Band Disease (BBD) on Pachyseris sp. and Brown Disease (BrB) on Acropora sp. Additionally, the effect of ambient temperature on transmission rates was investigated. The results demonstrated that BBD on Pachyseris sp. caused progressive tissue damage, characterized by zones of necrosis and distinctive black bands separating healthy tissue from dead tissue. At 31°C, the disease transmission rate increased twofold compared to 29°C, with an infection rate reaching 1.72 ± 0.76 cm/day. BrB on Acropora sp. showed the highest infection rate reaching 2.20 ± 0.41 cm/day at 29°C with a bacterial concentration of 106 CFU/ml. However, the infection rate decreased significantly at 31°C for all bacterial concentrations tested. The disease propagated linearly along the coral branches, manifesting as yellowish-brown discolouration attributable to symbiont ciliate activity. The virulence of pathogens such as Acinetobacter sp. increased at 31°C, accelerating the spread of necrosis through the production of toxins and enzymes that damage the coral epithelium. BrB symptoms appeared within 2 days at 29°C and only 1 day at 31°C. This study confirms that high temperature and sedimentation play a key role in accelerating disease dynamics in corals. Increasing seawater temperatures due to global climate change create ideal conditions for the spread of disease, threatening the sustainability of coral reef ecosystems. To mitigate these challenges, a multifaceted approach involving environmental management, carbon emission reduction, and the development of biotechnology to enhance coral resistance to pathogens is essential.
