Abstract

The existence of post-colonial Contemporary Islamic education cannot be separated from its historical dynamics in the colonial era, Islamic education was "forced" to face the challenges of secular education as part of the propaganda of the European colonialists, giving rise to various reactions from opposing attitudes as the attitudes of traditionalists, neo-traditionalists, reformers, and modernists. . The dualism of the post-colonial Islamic education system is one of the significant effects of the colonial heritage which is very difficult to resolve, this is due to the colonial government's discriminatory treatment of Islamic education so that Islamic education seeks and determines its own form as an educational institution that is separate from the education system managed by the State. The challenges and problems of Islamic education are increasingly complex in the face of global transformation, and advances in science and technology. The rapid flow of modernization is increasingly unstoppable with various positive and negative effects on human life. The contemporary era does not only occur at the global level, but the modern era is also part of the life of Muslim society. The importance of Islamic identity surviving the onslaught of secularization and globalization is an integral part of the task of Islamic education, so the transformation of the Islamic education system becomes a necessity to answer and become a solution for the community. The method used is a literature study with a qualitative research type through an analytical approach to literature review. Previous research as a source of information on the development of Islamic Religious Education research studies. The presence of an Integrated Islamic School in Indonesia is part of the reconstruction and modernization of the Islamic education system by integrating and integrating elements of management and curriculum content, learning methods, and community involvement in school governance so that its presence becomes part of an alternative solution as an Islamic educational institution in the era of contemporary, but the presence of the Integrated Islamic School as an upper secondary educational institution with high-cost standards so that it is not yet accessible to the average Muslim community

Abstract

In coal mining, to check the pH content of the water in the liquid waste from coal mining, most of the mining workers use conventional methods, namely by measuring using a digital pH meter or litmus paper periodically. Manual pH reading system makes handling slow. Based on these reasons the researchers designed a tool that can monitor pH values, the working principle of this tool is that the pH electrode is inserted into the sample solution, then the electrode detects the sample solution and changes the electrical signal, where the output will be amplified by an amplifier circuit in the form of an analog voltage, then on Arduino uno analog data is converted to digital data or ADC (Analog To Digital Conversion) after which it is converted again to pH value and displayed on an LCD that has been equipped with I2C. And this tool is also equipped with an RTC (Real Time Clock) so that it can display the time at which pH data is taken in the waste. The results of the calibration of the pH sensor obtained a linear equation, namely, Y = 25.84 - 7.1211X so that the designed tool has an error percentage of the manufacturer's pH meter tool of 1.028 %. By using this tool, the writer concludes that 0.4 grams of camphor (CaO) on the prototype or 480 kg in real conditions with a pool area of 600 m^3 can reduce the output voltage on the pH sensor from 3.20 V to 2.56 V thereby increasing the pH value. from 3.07 to 7.58 in pool 4 or drain pool.

Abstract

The development of electric vehicles today is not only focused on energy efficiency, but also on user comfort and safety. The 2kW BHARATA electric car, as one of the innovations of light electric vehicles, is designed to meet the needs of environmentally friendly mobility. However, ergonomic design is an important factor in preventing musculoskeletal disorders (MSDs) that are often experienced by vehicle users. This study aims to evaluate the ergonomic aspects of the driver's cabin design of the 2KW BHARATA electric car using the Rapid Upper Limb Assessment (RULA) method. The main problems in this study include: (1) how to apply the RULA method in analyzing the risk of discomfort or potential injury due to the driver's work posture, and (2) how the effect of variations in the angle and length of the driver's body posture on the level of comfort and risk of injury in the vehicle cabin. The research method used is a descriptive quantitative approach. The cabin design process was carried out using SolidWorks 2017 software, while the ergonomic analysis was carried out through simulation on CATIA V5 software. The simulation subjects were individuals with a height of 170 cm. The data obtained were analyzed to determine the ergonomic risk score based on the indicators in the RULA method. The results of the analysis show that the final RULA score is 4, which is included in the moderate risk category. This score indicates that the driver's working posture still needs adjustment to reduce the potential for musculoskeletal system disorders (MSDs), although it is not yet in the high-risk category. The conclusion of this study shows that the cabin design has met most of the ergonomic principles, but improvements are still needed to improve driver comfort and safety. Further researchers are advised to conduct a more comprehensive ergonomic analysis by considering anthropometric data from various user body sizes so that the vehicle design can be used optimally by users with various body postures.

Abstract

Enrekang Regency is one of the famous Arabica coffee-producing areas because it has a topography and climate that are suitable for the growth of coffee plants. Despite having suitable land for coffee cultivation, most coffee farmers still face several problems both internally and externally. Therefore, research is needed to determine the strategy for developing Arabica coffee farming businesses in Enrekang Regency by examining the analysis of internal and external factors. This research is a descriptive study using a qualitative approach. Respondents in this study were coffee farmers and traders, determined intentionally. Data collection used in the study included observation, interviews, and documentation. The data obtained were analyzed using SWOT analysis. Based on the results of the study, it shows that the strategy applied to coffee farming is in quadrant one, namely Aggressive (growth-oriented strategy), or is in a dynamic growth position, or is in a strength-opportunity strategy position (using strengths to take advantage of opportunities in decision making). This shows that there is an opportunity to develop Arabica coffee farming, in addition to having greater strengths compared to its weaknesses, it also has greater opportunities compared to its threats.

Abstract

Bioethanol merupakan senyawa alkohol yang diperoleh dari proses fermentasi biomassa dan termasuk golongan energi yang dapat diperbarui. Merupakan jenis bahan bakar yang menghasilkan polutan yang rendah, titik nyala tinggi, dan emisi hidrokarbon lebih sedikit sehingga dapat dimanfaatkan sebagai tambahan bahan bakar yang bisa berperan dalam performa motor. Penelitian ini membahas pengaruh penambahan bioethanol terhadap karakteristik performa motor 150 dan 160 cc menggunakan dynotest. Penambahan bioethanol 10 dan 20% terhadap bahan bakar jenis pertamax dan setiap sampel dilakukan pengujian sebanyak 3 kali.  Hasilnya menunjukkan bahwa penambahan bioethanol dapat meningkatkan torsi dan daya dari motor yang diuji. Torsi tertinggi pada motor 150 cc untuk bahan bakar pertamax murni tanpa ada penambahan bioethanol adalah 13,36 Nm. Pada penambahan bioethanol 10% torsi meningkat menjadi 13,94 dan 14,16 Nm ketika penambahan bioethanolnya 20%. Pada motor 160 cc torsi tertinggi yang diperoleh adalah 12,14 Nm untuk pertamax murni dan menjadi 15,01 Nm ketika ditambahkan bioethanol sebanyak 10%. Horse power tertinggi yang dapat dihasilkan pada motor 150 cc adalah 14,1 HP untuk pertamax murni dan masing-masing menjadi 14,8 dan 14,6 Nm ketika ditambahkan bioethanol sebanyak 10 dan 20%. Pada motor 160 cc horse power tertinggi yang dihasilkan adalah 12 HP untuk pertamax murni dan meningkat menjadi 13,8 HP ketika ditambahkan bioethanol sebanyak 10%. Dapat disimpulkan bahwa penambahan bioethanol berpengaruh terhadap peningkatan torsi dan daya pada motor. Namun, dengan persentase penambahan 20% cenderung menurunkan torsi dan daya yang dihasilkan.

Abstract

Power quality disturbances, such as voltage sag and swell, can lead to system instability and equipment damage. In this study, identification is defined as the process of detecting the presence and characteristics of these disturbances through time-frequency feature extraction using the Discrete Wavelet Transform (DWT). A Radial Basis Function Neural Network (RBFNN) is then employed as the classification method to determine the specific type of disturbance (sag or swell).The need for an automated identification and classification system arises because manual monitoring is slow and subjective, whereas industrial applications require rapid decisions based on measurable metrics. The disturbance dataset, specifically comprising voltage sag and voltage swell, was generated through modeling and simulation using MATLAB/Simulink. Features were extracted from the disturbance signals by decomposing them up to 7 levels with the DWT, using four different Mother Wavelets: Daubechies-4 (db4), Haar, Symlet-4 (sym4), and Coiflet-4 (coif4). These feature datasets were then normalized and divided into training, validation, and testing sets to train and evaluate the RBFNN model. Performance was assessed based on Mean Squared Error (MSE), classification accuracy, and the confusion matrix as objective success criteria. The results indicate that all models successfully achieved an MSE below 10-5 and 100% accuracy on the test data, signifying a very low error rate. The model utilizing the Haar wavelet demonstrated the best training efficiency, requiring the fewest epochs. Therefore, this combination is highly recommended for practical power quality monitoring applications Abstrak Gangguan kualitas daya , seperti Voltage Sag, dan Swell, dapat menyebabkan ketidakstabilan sistem dan kerusakan pada peralatan. Identifikasi pada penelitian ini didefenisikan sebagai proses mendeteksi keberadaan dan karakteristik gangguan melalui ekstraksi fitur waktu- frekuensi menggunakan Discrete Wavelet Transform (DWT) dan Radial Basis Function Neural Network (RBFNN) sebagai metode klasifikasi untuk proses menentukan jenis gangguan (sag dan swell). Kebutuhan akan sistem identifikasi dan klasifikasi otomatis diperlukan karena pemantauan manual bersifat lambat dan subjektif, sementara industri memerlukan keputusan cepat berbasis metrik yang terukur. Dataset gangguan, yang secara spesifik mencakup Voltage Sag dan Voltage Swell, dihasilkan melalui pemodelan dan simulasi dengan perangkat lunak MATLAB/Simulink. Fitur dari sinyal gangguan ini diekstraksi dari dekomposisi Discrete Wavelet Transform (DWT) hingga 7 level, dengan empat variasi Mother Wavelet (Daubechies-4, Haar, Symlet-4, dan Coiflet-4). Data fitur tersebut kemudian dinormalisasi dan dibagi menjadi data training, validation dan testing, untuk melatih dan menguji model RBFNN, yang kinerjanya dievaluasi berdasarkan Mean Squared Error (MSE), akurasi klasifikasi dan confusion matrix sebagai kriteria objektif keberhasilan. Hasil penelitian menunjukkan bahwa semua model berhasil mencapai MSE di bawah 10⁻⁵ dan akurasi 100% pada data uji, yang mengindikasikan tingkat kesalahan sangat rendah. Model berbasis wavelet Haar menunjukkan efisiensi pelatihan terbaik dengan jumlah epoch paling sedikit. Oleh karena itu, kombinasi ini sangat direkomendasikan untuk aplikasi pemantauan kualitas daya

Abstract

Khairul Ummah 2 Islamic Boarding School, located on Jalan Gajah, Bambu Kuning Village, Tenayan Raya District, Pekanbaru City, is equipped with facilities such as a mosque, madrasah office, teachers’ housing, dormitories, gazebos, and learning spaces. However, lighting in the gazebo area is still inadequate, limiting its use at night. Through this community service project, a solar-powered lighting system was designed and installed to support nighttime activities, particularly Qur’an memorization. The system includes a 12V 30Ah battery module, a 12V–24V 30A solar charge controller (SCC), 12V 30-watt LED lamps, and a 100 Wp solar panel mounted on the gazebo roof. During the day, the battery is charged via the solar panel, and at night it powers the lamps. Four lighting units were installed and donated to the school. Post-installation, light intensity was measured using a fluxmeter, yielding results between 173–245 lux. This range complies with Indonesian National Standard (SNI 03-6575-2001), which recommends 120–250 lux for reading or working areas. The lighting system is expected to enhance the comfort of students’ nighttime activities, particularly Qur’an memorization, which is more effective in a calm and relaxed evening environment.

Abstract

Budidaya ikan lele merupakan salah satu usaha di Pondok Pesantren Markiz Daarul Qur’an Kecamatan Lipat Kain, Kabupaten Kampar Kiri dengan tujuan untuk memenuhi kebutuhan sehari-hari bagi santri yang ada di pondok. Kegiatan utama pengabdian masyarakat ini adalah memanfaatkan teknologi tepat guna untuk pemberian pakan ikan lele di ponpes Markiz Daarul Qur’an sehingga kegiatan pemberian pakan ikan dapat diberikan secara teratur dan otomatis. Selain mempermudah dalam pemberian pakan juga mengurangi tingkat kanibalisme ikan lele, sehingga ikan lele dapat diproduksi dalam jumlah yang sama dengan padat tebarnya. Kegiatan ini dimulai dengan melakukan survei oleh tim pengabdian dan mahasiswa Kukerta. Kedatangan tim pengabdian disambut oleh pihak pesantren dan mengantar tim untuk melakukan pengecekan ke tempat kolam budidaya ikan lele yang menjadi tempat pemasangan alat teknologi tepat guna (TTG) pemberi pakan ikan otomatis. Kondisi kolam dalam keadaan baik. Padat tebar benih ikan lele yang dibudidayakan yaitu 750 ekor, dengan jadwal pemberian pakan pada tiga waktu yaitu, jam 07.00 WIB untuk pagi hari, jam 15.00 WIB untuk sore hari dan jam 21.00 WIB untuk malam hari. Penerapan TTG pemberian pakan ikan lele di ponpes ini secara tidak langsung telah membantu  biaya operasional dan penyelenggaraan pendidikan santrinya, karena kebanyakan berasal dari golongan masyarakat kurang mampu dan anak yatim dari berbagai usia.
