Abstrak: Banyak cara yang ditempuh oleh pemerintah untuk mewujudkan sumber daya manusia Indonesia dengan kemampuan intelektual yang dapat bersaing dengan daerah bahkan dengan Negara lain, salah satunya dengan diadakan Olimpiade Matematika baik tingkat SD/MI, SMP/MTs., SMA/SMK/MA bahkan tingkat Mahasiswa. Namun terkadang yang bisa menikmati kegiatan olimpiade tersebut hanyalah sekolah-sekolah tertentu saja. Hal tersebut disebabkan masih kurangmya sosialisasi yang dilakukan pemerintah mengenai kegiatan tersebut serta faktor dari sekolah itu sendiri yang masih memiliki rasa minder untuk bersaing dengan sekolah-sekolah lain. Tujuan dalam kegiatan pelatihan ini adalah untuk meningkatkan kemampuan peserta didik dalam menyelesaikan soal-soal Olimpiade Matematika. Penyelenggaraan kegiatan ini dilaksanakan di SMAN 2 Tanjung Balai, dengan metode memberikan pelatihan dan strategi pelatihan yang sudah disiapkan oleh tim penulis. hasil pelatihan tersebut, bahwa siswa sangat antusias dalam membahas soal-soal Olimpiade Matematika dengan trik yang diberikan dan mereka pun dapat dengan mudah menjawab soal-soal yang diberikan tanpa kendala yang berarti diharapkan mampu menghasilkan bibit-bibit baru dari pemenang Olimpiade Matematika.

sed vertical hydroponic farming system integrated with LED grow light technology and catfish aquaponics. The proposed system combines vertical hydroponics and aquaponics to optimize plant growth and water utilization. Internet of Things technology enables real-time environmental monitoring through an Arduino Uno microcontroller integrated with LDR, soil moisture, pH, and NPK sensors. The obtained sensor data is processed using the Mamdani Fuzzy Logic algorithm, which performs fuzzification, rule inference, aggregation, and defuzzification to generate adaptive control decisions for irrigation, nutrient circulation, and LED grow light intensity. This research uses the Research and Development (R&D) method through prototype development and performance evaluation for 30 days using spinach (Amaranthus spp.) and mustard greens (Brassica juncea) as test plants. Experimental results showed that the developed system successfully maintained stable environmental conditions, with soil moisture ranging between 69–72%, a pH value between 6.4 and 6.6, and optimal nutrient availability. Plant growth increased significantly. The integration of IoT, AI and aquaponics improves cultivation efficiency, enabling environmental control as a smart and sustainable solution for urban agriculture.

Abstract:Abstract: The assessment of PKH employees in Batu Bara Regency still requires an objective and measurable evaluation process to support performance decisions. Manual assessment can cause subjectivity and take more time,…
especially when several criteria must be considered. This study aims to apply the Simple Additive Weighting (SAW) method to the PKH employee assessment system in Batu Bara Regency. The criteria used in this assessment are attendance, teamwork, responsibility, communication, and length of service. The SAW method is applied by determining criteria weights, converting employee values, normalizing the decision matrix, and calculating preference values to obtain the final ranking. The results show that alternative A1, Rahmi Rizkya, obtained the highest score of 0.9504 and ranked first, while alternative A5, Toni Syahpradanadaely, obtained the lowest score of 0.4831. Based on these results, the SAW method can help the employee assessment process become more objective, structured, and useful as a reference for evaluating PKH employee performance.

Abstrak: Penilaian pegawai PKH Kabupaten Batu Bara membutuhkan proses evaluasi yang objektif dan terukur untuk mendukung pengambilan keputusan terhadap kinerja pegawai. Penilaian yang masih dilakukan secara manual dapat menimbulkan subjektivitas dan membutuhkan waktu lebih lama, terutama jika penilaian melibatkan beberapa kriteria. Penelitian ini bertujuan untuk menerapkan metode Simple Additive Weighting (SAW) pada sistem penilaian pegawai PKH Kabupaten Batu Bara. Kriteria yang digunakan dalam penilaian meliputi kehadiran, kerja sama tim, tanggung jawab, komunikasi, dan masa kerja. Metode SAW diterapkan melalui penentuan bobot kriteria, konversi nilai pegawai, normalisasi matriks keputusan, serta perhitungan nilai preferensi untuk memperoleh hasil perankingan. Hasil penelitian menunjukkan bahwa alternatif A1 atas nama Rahmi Rizkya memperoleh nilai tertinggi sebesar 0,9504 dan menempati peringkat pertama, sedangkan alternatif A5 atas nama Toni Syahpradanadaely memperoleh nilai terendah sebesar 0,4831. Berdasarkan hasil tersebut, metode SAW dapat membantu proses penilaian pegawai menjadi lebih objektif, terstruktur, dan dapat dijadikan acuan dalam evaluasi kinerja pegawai PKH.

tric shapes. The development process adopted the Multimedia Development Life Cycle (MDLC) model, which consists of six systematic stages: concept, design, material collecting, assembly, testing, and distribution. The research concentrated on the development and expert validation stages. Validation results from content and media experts indicate that the application meets pedagogical and technical feasibility standards. The content expert confirmed that the materials align with the national mathematics curriculum and are presented in a clear, contextual, and accurate manner, while the media expert highlighted the user-friendly interface, interactive features, and visual appeal of
the application. Theoretically, this AR-based medium bridges the gap between abstract mathematical concepts and concrete visualization by enabling students to interact directly with
virtual 3D objects. Practically, the application enhances learning motivation and engagement by providing dynamic, interactive experiences. Overall, this research contributes to the
advancement of educational technology by offering a systematic model for developing AR-based learning media that support active and meaningful learning in the digital
era.

in PostgreSQL, compare the effectiveness of B-Tree and Hash indexes, and evaluate their influence on query planner decisions. A quantitative experimental approach was employed using the TPC-H benchmark dataset at scale factors SF0.1, SF1, and SF10. Experiments were conducted using EXPLAIN ANALYZE on exact match, range, and join queries under three conditions: without indexing, with B-Tree indexing, and with Hash indexing. The results demonstrate that indexing significantly improves query performance. For exact match queries on the SF10 dataset, execution time decreased from 93.36 ms without indexing to 0.034 ms using B-Tree and 0.045 ms using Hash indexes. For join queries, execution time was reduced from 857.77 ms to 0.180 ms using B-Tree and 0.079 ms using Hash indexes. B-Tree showed consistent performance across different query types, while Hash achieved the best results for equality-based queries. Furthermore, index usage influenced query planner decisions in selecting more efficient execution strategies. These findings indicate that appropriate index selection can substantially improve data access efficiency in PostgreSQL.

Abstrak: Performa query merupakan faktor penting dalam pengelolaan basis data berskala besar. Salah satu teknik optimasi yang umum digunakan adalah indexing. Penelitian ini bertujuan menganalisis pengaruh penggunaan indexing terhadap performa query pada PostgreSQL, membandingkan efektivitas B-Tree dan Hash index, serta mengevaluasi pengaruhnya terhadap keputusan query planner. Penelitian menggunakan metode eksperimen kuantitatif dengan dataset benchmark TPC-H pada skala SF0.1, SF1, dan SF10. Pengujian dilakukan menggunakan EXPLAIN ANALYZE pada exact match query, range query, dan join query dalam kondisi tanpa index, menggunakan B-Tree index, dan Hash index. Hasil penelitian menunjukkan bahwa indexing meningkatkan performa query secara signifikan. Pada exact match query dataset SF10, execution time menurun dari 93,36 ms tanpa index menjadi 0,034 ms menggunakan B-Tree dan 0,045 ms menggunakan Hash index. Pada join query, execution time berkurang dari 857,77 ms menjadi 0,180 ms menggunakan B-Tree dan 0,079 ms menggunakan Hash index. B-Tree menunjukkan performa yang konsisten pada berbagai jenis query, sedangkan Hash index memberikan performa terbaik pada query berbasis equality. Selain itu, penggunaan index memengaruhi keputusan query planner dalam memilih strategi eksekusi yang lebih efisien. Hasil penelitian menunjukkan bahwa pemilihan metode indexing yang tepat dapat meningkatkan efisiensi akses data pada PostgreSQL
