Abstract

This study aims to design and implement an Internet of Things (IoT)-based monitoring system for detecting electric pole tilt and Public Street Lighting (LPJU) failures. Stable pole structures and optimal street lighting are critical to ensure public safety and comfort, especially at night. However, manual inspections are inefficient and often fail to provide early detection of infrastructure damage. The system was developed using NodeMCU ESP8266 integrated with a potentiometer-based tilt sensor and a voltage sensor. The sensors acquire data on pole tilt and LPJU status, which are transmitted via Wi-Fi to a web-based monitoring application. Experimental procedures were carried out through laboratory testing and limited field simulations to evaluate both hardware and software performance. The test results show that the tilt sensor provides a linear response between the tilt angle and the output voltage, allowing accurate detection of pole inclination. In addition, the system successfully identified LPJU conditions (on/off) and displayed them in real-time on the monitoring dashboard. In conclusion, the proposed IoT-based monitoring system has proven reliable in detecting pole tilt and LPJU failures. This approach not only improves the efficiency of infrastructure maintenance but also contributes to the development of smart city solutions through more advanced and real-time monitoring technologies

Abstract

Indonesia merupakan negara yang memiliki curah hujan cukup tinggi pada musim penghujan hampir keseluruhan daerah diguyur hujan dengan intensitas yang tinggi, sehingga perlu diwaspadai akan terjadinya banjir. Namun jika terjadi kelalaian dalam pengawasan bendungan tersebut akibatnya sangat merugikan karena menyangkut keselamatan warga disekitarnya jika terjadi meluapnya air. Oleh karena itu penulis bertujuan membuat sistem monitoring bendungan berbasi IoT, dimana sistem ini bukan hanya sebatas mengontrol ketinggian air, serta mengotomatisasi buka tutup pintu air pada bendungan, tetapi sistem monitoring ini dapat juga dikontrol setiap saat untuk disiarkan langsung atau live streaming dan diberitahukan melalui situs web ketika air meluap. Penelitian ini menggunakan metode penelitian kuantitatif dengan pendekatan eksperimen, jenis penelitian yang dapat dilakukan dalam penelitian sistem monitoring bendungan ini yaitu "eksperimen lapangan". Dari hasil pengujian, didapatkan bahwa jarak air ke sensor lebih dari 11 cm maka status yang tampil pada website adalah Normal dan pintu air dalam keadaan tertutup, jika jarak air ke sensor lebih dari atau sama dengan 10 cm dan kurang dari 11 cm maka status yang tampil pada website adalah Siaga 3, pada saat ini pula pesan whatsapp akan terkirim ke penjaga bendungan untuk menginformasikan bahwa air mengalami kenaikan, jika jarak air ke sensor lebih dari atau sama dengan 9 cm dan kurang dari 10 cm maka status yang tampil pada website adalah Siaga 2, pada saat ini pula pesan whatsapp akan terkirim ke penjaga bendungan untuk menginformasikan bahwa air mengalami kenaikan dan secara otomatis motor servo akan berputar 900 dan pintu bendungan akan terbuka setengah jika jarak air ke sensor kurang dari atau sama dengan 8 cm maka status yang tampil pada website adalah Siaga 1 dan sirine akan berbunyi serta secara otomatis motor servo akan berputar untuk membuka pintu air 1800 dan lagi pesan whatsapp akan terkirim ke penjaga pintu untuk menginformasikan bahwa ketinggian air dalam status siaga 1, serta fitur tambahan yaitu live streaming yang berfungsi sebagai pengontrol kondisi sekitar pintu bendungan apakah benar sensor ultrasonik mendeteksi kenaikan air atau tidak, kesemua alat yang digunakan dapat berfungsi dengan baik. hasil pengujian yang didapatkan nilai error rata-rata adalah 0,72% dan tingkat akurasi sebesar 99,28% dengan mengambil 15 sampel jarak dan air ditambahkan setiap 1 cm, pengujian ini dilakukan pada keadaan air yang tenang tanpa adanya gelombang atau riakan. Dan diperoleh kesimpulan bahwa pembacaan sensor dengan penggaris akurat dan alat berfungsi dengan baik.

Abstract

In the context of toxic business competition, this research investigates the legal protection of Micro, Small, and Medium Enterprises (MSMEs) in Indonesia, particularly in partnerships with large corporations. The primary emphasis is on the implementation of Law Number 5 of 1999, which prohibits monopolistic practices and unfair business competition, and Law Number 20 of 2008, which pertains to small and medium-sized enterprises. Data was collected from literature studies, pertinent regulations, and in-depth interviews with relevant stakeholders using a qualitative approach and a case study design. The research results show that although the legal framework already exists, effective implementation still requires improvement. MSMEs face various challenges in partnerships with large companies, including access to resources and greater risks in business transactions. Recommendations are prepared to strengthen legal protection through regulatory revisions, strengthening legal institutions, legal education, developing partnerships, and stricter law enforcement. The main aim is to increase fairness in business relations between MSMEs and large companies, as well as support inclusive and sustainable economic growth in Indonesia. It is hoped that the implications of this research can provide a positive contribution in renewing policies that support the development of MSMEs as the backbone of the national economy.

Abstract

Perpustakaan perguruan tinggi memiliki tanggung jawab untuk menyediakan koleksi yang relevan dan berkualitas guna mendukung kegiatan pendidikan, penelitian, dan pengembangan ilmu pengetahuan. Namun, pertambahan koleksi yang tidak diimbangi dengan pengelolaan yang tepat dapat menyebabkan penumpukan bahan pustaka yang tidak lagi sesuai kebutuhan pengguna. Salah satu upaya yang dilakukan untuk menjaga kualitas koleksi adalah kegiatan penyiangan (weeding), termasuk penyiangan koleksi skripsi. Artikel ini membahas pelaksanaan penyiangan koleksi skripsi yang dilakukan oleh mahasiswa Jurusan Ilmu Perpustakaan UIN Alauddin Makassar melalui kegiatan Praktik Kerja Lapangan (PKL) di Perpustakaan Politeknik Ilmu Pelayaran Makassar. Metode pelaksanaan dilakukan secara tatap muka dalam lingkungan kerja nyata selama satu bulan lebih, dengan pendampingan pustakawan dan dosen pembimbing. Tahapan kegiatan meliputi identifikasi koleksi, seleksi berdasarkan kriteria relevansi dan kondisi fisik, serta dokumentasi hasil penilaian. Hasil kegiatan menunjukkan bahwa penyiangan berdampak positif terhadap peningkatan kualitas koleksi, efisiensi ruang penyimpanan, dan kemudahan temu kembali informasi. Selain itu, kegiatan ini memberikan pengalaman praktis bagi mahasiswa dalam menerapkan teori manajemen koleksi, meningkatkan kompetensi profesional, dan memperkuat kesiapan mereka memasuki dunia kerja. Dengan demikian, penyiangan koleksi skripsi tidak hanya mendukung optimalisasi layanan perpustakaan, tetapi juga berperan sebagai sarana pembelajaran berbasis praktik bagi mahasiswa.

Abstract

This study presents the design of a 10-ton capacity solar-powered cold storage system for the Cituis Fish Auction Site (TPI) in Tangerang, Indonesia, as a sustainable solution to support the coastal fisheries sector. The system comprises two temperature zones: an anteroom at 5°C and a freezer room at -30°C, both integrated with a hybrid system utilizing solar panels and batteries. The total power consumption of the cooling system reaches 27.51 kW. The simulation results, obtained using HOMER Pro software, indicate that the hybrid PV system can reduce CO2 emissions by up to 16,754 kg per year. From an economic perspective, the system shows high feasibility with a payback period of only 0.41 years, a capital expenditure (CAPEX) of IDR 745.29 million, and a monthly operational cost (OPEX) of IDR 9.7 million. These findings confirm that the system is both technically and economically viable and can be replicated in other coastal regions.
