Abstract

Cikarawang Village, Dramaga, Bogor is a village with a large potential for water resources. However, the water in this village has high levels of Mg2+ and Mn2+. High levels of Mg2+ and Mn2+ can cause eye and nose irritation, as well as influenza symptoms. To reduce the levels of Mg2+ and Mn2+ in water, this study used the adsorption method using activated carbon and bentonite. The results of the study showed that the levels of Mg2+ and Mn2+ in water can be significantly reduced using the adsorption method. In sample 1, the level of Mg2+ decreased from 14.64% to 11.64% after adsorption for 30 minutes. In sample 2, the level of Mg2+ dropped to 0% after adsorption for 30 minutes. In sample 3, the level of Mg2+ decreased from 9.60% to 5.76% after adsorption for 30 minutes. In general, the longer the contact time between the sample and the adsorbent, the greater the decrease in the levels of Mg2+ and Mn2+. However, for sample 2, the level of Mg2+ dropped to 0% after adsorption for 30 minutes. This indicates that sample 2 has a very high level of Mg2+ that can be adsorbed perfectly by bentonite in a short time. This study concluded that the adsorption method using activated carbon and bentonite is an effective method for reducing the levels of Mg2+ and Mn2+ in water.

Abstract

This study aims to examine the decomposition method of liquid waste in the home industry, especially in the tofu industry, by using non-thermal plasma and electrocoagulant methods that are environmentally friendly and with low energy. In this study, the plasma method, electro-coagulant method, and a combination of both (electro-coagulant followed by plasma method and plasma followed by electro-coagulant method) were used to decompose liquid waste in the tofu industry. The results showed that non-thermal plasma followed by the electrocoagulation method was the most effective in reducing the T.D.S. value of 1983 ppm (the minimum value of the total control T.D.S. was around 2702 ppm), the minimum value of electrical conductivity (E.C.) was around 3967 (μs/cm), and also obtained a value of 3967 (μs/cm). pH 7.0. Based on the research results, non-thermal plasma combined with the electrocoagulant method can be applied to more optimally decompose liquid waste, especially in the tofu industry. The combination method of plasma and electrocoagulation to decompose the tofu industrial wastewater, which is environmentally friendly, is the novelty of this research

Abstract

Brass (CuZn) is widely used today due to better mechanical, thermal, and chemical properties. The present research fabricated CuZn alloy by adding various Zn (6, 9, and 12 wt.%) to the Cu using gravity casting. Casts CuZn alloy by adding various Zn to the Cu to investigate optimum composition were resulting highest inhibited of bacterial activity. In addition, the structure, hardness, and electrochemical behavior of the alloy were also investigated using XRD, Vickers hardness, and potentiostat equipment. XRD confirmed that CuZn alloy has an alpha phase, and a FCC crystal structure. The rise of the Zn content in the alloy led to an increase in crystallite size, a decrease in the hardness and a shift to a more negative OCP potential at 1200 s measurement. Enhancing the Zn content to 9 wt.% in the alloy lead to decrease the corrosion rate. Moreover, 24-hour post-contact observation found that the sample places removed remained clear of bacteria. The Cu6Zn sample successfully inhibited the growth of Escherichia coli in the 3rd hour, while Staphylococcus aureus was 100 % reduced in the 7th hour. The Cu6Zn sample could be used as an alternative material for medical equipment in ambulances.

Abstract

Keberhasilan proses pemboran sumur minyak tergantung pada kualitas dan campuran semen pemboran. Perencanaan komposisi pembuatan bubur semen yaitu air, bahan tambahan, atau campuran tambahan lainnya perlu dianalisa untuk menghasilkan sifat-sifat bubur semen yang diinginkan. Tujuan penelitian adalah untuk mengetahui komposisi dan sifat fisik bubur semen dengan penambahan zat adiktif cangkang kerang pada tiga variasi suhu waktu pengentalan, kuat tekan, dan rheologi bubur semen. Metodologi penelitian, desain penelitian kuantitatif menguji pengaruh penambahan aditif terhadap berbagai sifat fisik bubur semen. Pelaksanaan sesuai dengan protokol penelitian yang telah disusun. Analisis dengan mengukur waktu penebalan, kuat tekan, dan reologi bubur semen menggunakan peralatan vicat, dengan memperhatikan kondisi tekanan dan suhu standar API 10A. Hasil penelitian, pengujian semen kelas G dengan aditif kerang pada kadar air 44% menunjukkan hasil penurunan kuat tekan dengan setiap penambahan konsentrasi aditif. Penambahan aditif clamshell pada kadar air 44% dengan tiga variasi temperatur yaitu 80°F, 140°F, dan 200°F waktu perendaman selama 24 jam dan 8 jam. Suhu memiliki pengaruh yang besar terhadap uji waktu pengentalan sampel semen dan waktu perendaman akan berpengaruh lebih besar terhadap penambahan aditif kerang. Hasil uji waktu pengentalan semen kelas G dengan penambahan aditif cangkang kerang pada substitusi cangkang kerang 0%, 15%, 20%, 25% dan 50%, menunjukkan bahwa semakin banyak substitusi cangkang kerang maka semakin cepat waktu pengeringan pada pembacaan vicat dan hasil yang sama Ditemukan juga pada uji kuat tekan ekosemen pada substitusi cangkang kerang 0%, 15%, 20%, 25% dan 50% menunjukkan penurunan nilai kuat tekan dengan semakin banyak substitusi shell ditambahkan.

Abstract

Keterbatasan penguasaan teknologi digital, khususnya Artificial Intelligence (AI), masih menjadi tantangan bagi tenaga pengajar di Pondok Pesantren Madinatunnajah. Padahal, penguasaan teknologi tersebut semakin relevan dalam menunjang efektivitas pembelajaran di era transformasi digital. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan kapasitas tenaga pengajar pondok pesantren dalam memahami dan memanfaatkan AI secara praktis dalam kegiatan belajar mengajar. Kegiatan ini dilaksanakan melalui pelatihan berbasis pemaparan materi, diskusi interaktif, dan praktik langsung, yang kemudian dievaluasi menggunakan pendekatan deskriptif kuantitatif melalui survei terhadap 19 peserta.Hasil evaluasi menunjukkan bahwa pelatihan memberikan dampak positif yang nyata, tercermin dari peningkatan rata-rata kemampuan peserta dari skor 2,11 menjadi 2,89. Visualisasi boxplot menunjukkan peningkatan yang merata dan konsisten, sementara analisis heatmap dan radar chart memperlihatkan penilaian tinggi terhadap efektivitas metode pengajaran dan relevansi materi pelatihan. Dampak kegiatan ini dirasakan langsung oleh mitra, yakni tenaga pengajar di Madinatunnajah, yang kini memiliki pengetahuan dan keterampilan dasar dalam mengintegrasikan AI ke dalam proses pembelajaran. Selain itu, kegiatan ini mendorong terbangunnya budaya literasi digital di lingkungan pesantren serta menjadi model awal integrasi teknologi dalam pendidikan berbasis keagamaan. Program ini diharapkan menjadi langkah awal dalam menciptakan guru-guru pesantren yang adaptif terhadap perkembangan teknologi pendidikan.
