Abstract

— This study developed a hydroponic control system to regulate nutrient concentration (PPM) and water volume using a Proportional-Integral (PI) controller. The PI controller was chosen for its simplicity and effectiveness in systems that do not require fast response times. A trial-and-error method was used to tune the Kp and Ki values, which were implemented in an ATMega328 microcontroller. The system consists of one AC pump and two DC pumps: DC Pump-1 controls the PPM by supplying liquid fertilizer, while DC Pump-2 regulates the water volume. The results showed that modifying the PI controller with an integrator limitation improved performance. For PPM control, a limit of 13000 with Kp = 2 and Ki = 0.01 resulted in a 0.5% error, 56.8-second rise time, and a 4.8% overshot. For water level control, a limit of 12000 with Kp = 100 and Ki = 0.16 yielded a 3.25% error, 2% overshot, and a 65.4-second rise time. The test results demonstrated that the use of AB Mix can be reduced by up to 26% compared to a conventional PID, with an initial PPM value of around 350.

Abstract

Tujuan: Penelitian ini bertujuan menganalisis pengaruh pengungkapan Environmental, Social, and Governance (ESG) terhadap reaksi pasar dengan volatilitas harga saham sebagai variabel moderasi pada perusahaan transportasi dan logistik yang terdaftar di Bursa Efek Indonesia (BEI). Desain Penelitian dan Metodologi: Pendekatan yang digunakan adalah kuantitatif eksplanatori dengan desain kausal komparatif. Sampel penelitian dipilih secara purposive sampling dari perusahaan transportasi dan logistik periode 2019–2023. Data sekunder diperoleh dari laporan tahunan, laporan keberlanjutan, dan basis data keuangan seperti Refinitiv dan Yahoo Finance. Pengungkapan ESG diukur melalui content analysis berdasarkan pedoman GRI, sedangkan reaksi pasar diukur menggunakan abnormal return. Analisis data dilakukan dengan regresi linear berganda dan Moderated Regression Analysis (MRA). Hasil dan Pembahasan: Hasil penelitian menunjukkan bahwa pengungkapan ESG berpengaruh signifikan terhadap reaksi pasar dengan nilai koefisien determinasi (R²) sebesar 0,767. Secara parsial, aspek environmental dan governance berpengaruh positif signifikan terhadap reaksi pasar, sedangkan aspek social berpengaruh negatif signifikan. Volatilitas harga saham berpengaruh negatif terhadap reaksi pasar dan terbukti memperlemah hubungan antara ESG dan reaksi pasar. Hal ini menandakan bahwa praktik lingkungan dan tata kelola yang baik diapresiasi pasar, sementara aktivitas sosial belum dianggap memberikan nilai ekonomi langsung bagi investor. Implikasi: Penelitian ini menegaskan pentingnya pengungkapan ESG yang konsisten dan transparan dalam membangun kepercayaan investor serta memperkuat reputasi perusahaan. Bagi regulator, hasil ini mendukung penguatan kebijakan pelaporan keberlanjutan, sedangkan bagi manajemen, menjadi dasar strategis dalam meningkatkan nilai perusahaan melalui praktik lingkungan dan tata kelola yang baik.

Abstract

Kecakapan dalam menyelesaikan persoalan matematika adalah bagian dari keterampilan mendasar yang perlu dipunyai oleh kalangan siswa SMA agar dapat mengembangkan solusi terhadap permasalahan kehidupan dan kompetensi ini krusial bagi siswa dalam menyelesaikan soal matematika. Fakta di lapangan menunjukkan bahwa keterampilan tersebut masih berada di bawah harapan dan belum optimal. Penelitian ini bertujuan untuk mengetahui perbedaan capaian belajar siswa yang mendapatkan pembelajaran dengan pendekatan open-ended dan konvensional. Penelitian ini menggunakan pendekatan kuantitatif dengan populasi adalah siswa kelas X SMAN 5 Banda Aceh dan teknik pemilihan sampel adalah simple random sampling. Sampel yang terpilih adalah siswa kelas X-2 sebagai kelas kontrol dan siswa kelas X-3 sebagai kelas eksperimen. Pengumpulan data dilakukan dengan pemberian tes awal dan akhir setelah perlakuan, selanjutnya setelah data terkumpul dianalisis dengan menggunakan uji-t setelah uji normalitas dan homogenitas data terpenuhi. Hasil penelitian didapatkan bahwa keterampilan pemecahan masalah matematika pada siswa yang diajarkan dengan pendekatan open-ended lebih baik dibanding dengan siswa yang diajarkan dengan pendekatan konvensional.

Abstract

This study aims to determine the impact of Regional Original Revenue (PAD), Balancing Funds (DP) consisting of the General Allocation Fund (DAU), Special Allocation Fund (DAK), and Revenue Sharing Fund (DBH), as well as the Gross Regional Domestic Product (GRDP) on the Human Development Index (HDI). The research was conducted using a quantitative descriptive method aimed at explaining empirical phenomena supported by patterns of relationships among variables, characteristics, and statistical data. Secondary data in the form of time series data over 15 years (2010–2024) were analyzed using multiple linear regression.The results of the statistical analysis show that PAD and DP each have no positive and significant effect on HDI when tested partially. Meanwhile, GRDP has a positive and significant partial effect on HDI. However, simultaneously, the variables PAD (X1), DP (X2), and GRDP (X3), based on the F-test hypothesis, have a positive and significant effect on HDI. In other words, these three variables, both directly and indirectly, contribute jointly to the achievement of the HDI score in Sleman Regency during the study period. In 2024, Sleman’s HDI reached 84.91, classified as “Very High,” surpassing the HDI of Yogyakarta Special Region Province in 2024, which was 81.62 (“Very High”), and the national HDI of 75.02 (“High”), an achievement truly worthy of appreciation.

Abstract

Soil moisture monitoring is essential for precision agriculture to optimize irrigation and increase crop productivity. Traditional conductivity-based sensors often face limitations such as low sensitivity, slow response, and measurement instability. This study presents a simple and effective enhancement method by applying a graphene coating on copper electrodes using the drop casting technique. Experimental evaluations were conducted on natural soil samples at varying moisture levels. The graphene-coated sensor exhibited a significantly higher sensitivity of 23.0 Ω/% compared to 12.0 Ω/% for the uncoated sensor, a faster response time of approximately 5 seconds, and improved measurement consistency with a reduced standard deviation of ±15 Ω. Graphene's superior electrical conductivity and strong water affinity are key factors contributing to this performance improvement. These findings indicate that graphene-coated sensors offer a promising solution for reliable, cost-effective soil moisture monitoring in smart farming systems.

Abstract

Numeracy skills are essential for daily life and must be mastered by students. However, data from PISA and TIMSS indicate that Indonesian students' numeracy skills are still low. One contributing factor is the limited availability of numeracy-based learning materials, which reduces students' familiarity with numeracy-oriented problems. Therefore, this study aimed to develop a numeracy e-module on geometry for eighth-grade junior high school students. This study employed a research and development (R&D) method using the ADDIE model, consisting of analysis, design, development, implementation, and evaluation stages. The participants included students and teachers from SMPN 2 Banda Aceh. Data were analyzed using qualitative techniques to describe interview results and quantitative techniques to analyze validation, readability, and practicality data. The results showed that the e-module achieved an average score of 4.37 for material presentation and assessment and 4.53 for media and language aspects, both categorized as very valid. The practicality evaluation indicated positive responses, with average scores of 4.46 from teachers and 4.35 from students, both categorized as very practical. These findings indicate that the developed numeracy e-module on geometry is valid and practical for use in junior high school mathematics learning.
