Abstract

Saat ini dunia pemasaran sangat berkembang, persaingan barang dan jasa juga sangat ketat, hal ini membutuhkan suatu strategi pemasaran yang tepat agar dapat memasarkan produk dengan baik dan dapat mengembangkan pangsa pasar yang telah di tentutkan. Kota Batu merupakan kota yang sangat potensial untuk segala produk, karena Kota batu merupakan kota wisata yang mana banyak para wisatawan datang dan berkunjung ke tempat wisata dan produk Kota Batu merupakan icon Kota Batu. Fungsi manajemen sebagai fasilitator antara produsen dengan konsumen. Tujuan penelitian ini adalah untuk mengetahui strategi pemasaran yang di terapkan Koperasi Unit Desa (KUD) Batu untuk produk Susu Nandhi Murninya, serta kendala-kendala yang di hadapi dalam mengembangkan pangsa pasarnya. Dalam penelitian ini penulis menggunakan jenis penelitian Kualitatif Deskriptif yang bertujuan untuk mendeskripsikan analisis strategi pemasaran dengan teknik observasi, wawancara atau interview dan dokumentasi. Sedangkan data yang di dapat dianalisis dengan menggunakan analisis lingkungan Internal-Eksternal atau SWOT (Strenght, Weakness, Opportunities, Threats) untuk mendeskripsikan posisi perusahaan serta memperoleh pemecahan masalah dengan mempertimbangkan alternatif strategi pemasaran yang tepat dari hasil analisis SWOT. Dari hasil penelitian yang telah di lakukan dapat di tarik kesimpulan bahwa strategi yang di gunakan oleh  Koperasi Unit Desa (KUD) Batu untuk produk Susu Nandhi Murninya adalah bersifat personal selling, dan promosi yang dilakukan Koperasi Unit Desa (KUD) melalui brosur, acara-acara tertentu seperti pada waktu pameran, bazar, dan rakernas untuk lebih mengenal produk susu Koperasi Unit Desa (KUD). Dari hasil analisis SWOT dapat diketahui bahwa Koperasi Unit Desa (KUD) berada pada posisi pertumbuhan melalui integritas horizontal, yang mana pada posisi ini paling baik menerapkan strategi intensif yaitu pengembangan pasar. Kata Kunci : Strategi Pemasaran, SWOT (Strenght, Weakness, Opportunities, Threats), Dan Pengembangan Pangsa Pasar

Abstract

Background: Pacitan Regency, located between hills, mountains, and waters, boasts abundant natural resources, including geothermal potential and renewable energy. However, its remote location, far from the capital of East Java, has led to underutilization of these resources, particularly in the tourism sector. Objective: This initiative aims to develop eco-friendly tourist destinations integrated with IoT technology to enhance Pacitan's branding and recognition. Method: The project involves planning through Forum Group Discussions (FGD) and socialization, followed by technical implementation, publicity, recruitment of local cadres, and signing of integrity pacts. Subsequent steps include strengthening local identity, implementation, and program monitoring and evaluation. Results: The partnership has effectively addressed challenges related to infrastructure and planning for renewable energy and IoT-based geothermal tourism while adhering to sustainable development principles. Conclusion: The activity was successfully executed, receiving strong support from regional figures. The material delivery was precise, the target participant numbers were met, and there was significant collaboration with local communities and universities. The project has not only helped local partners but also contributed to Pacitan's potential for sustainable tourism development.

Abstract

The utilization of solar energy as a renewable and environmentally friendly energy source, which is inexhaustible, is an ideal solution to meet the growing demand for electricity. Solar Home Energy refers to a house powered by solar energy. The solar energy is subsequently stored in batteries using a battery charger. In this paper, a forward DC-DC converter is used as a battery charger to supply power to a self-sufficient house from solar energy, stored in a 96 V 45 Ah battery. A fuzzy logic controller is employed to regulate the output of the forward DC-DC converter, ensuring a constant charging voltage according to the set point. The output of this project is designed for 110 V 4.5 A; however, in practice, the forward DC-DC converter only achieved a charging voltage of 100.5 V, resulting in an error of 8.63% from the planned value. Additionally, the charging current reached 1.4 A, leading to a significant error of 63.89% from the planned charging current.

Abstract

The renewable energy system (RES) has recently become hot topic due to its unlimited, green energy potential, and the maturity of its technology. A solar charging controller (SCC) is required to regulate parameters for the battery and is an essential component for sustainable and renewable energy usage. An SCC based on a DC-DC Buck converter with cascaded proportional-integral (PI) controller is used in the system for managing the current and voltage loops, thereby preventing battery overcharging. The control parameters are determined using the Ziegler-Nichols method based on the reaction curve. A first -order system is employed due to the open-loop responses show no overshoot and oscillations. MATLAB software is used for both simulation and controller design. Simulations are conducted to validate the proposed SCC with the cascaded controller. Variations in the state of charge (SoC) are presented in two cases: without and with the controller. The SoC is set 20%, 50%, and 95%. A high SoC percentage indicates that the battery is near the full capacity, whereas a low percentage indicates that battery is near empty. Using the cascaded controller, both current and voltage responses at different SoC levels demonstrate satisfactory performance, including rapid transient responses, minimal overshoot, small ripples, and robustness.

Abstract

The need for a smart grid has been spurred by the growth of distributed generation, the aging of the current grid infrastructure, and the desire to alter networks. The development and enhancement of smart grid technology is significantly facilitated by the Internet of Things (IoT) technology. Batteries play a crucial role in the energy storage of electrical systems, including smart microgrids and electric vehicles. To enhance performance and prolong battery life, a Battery Monitoring System (BMS) is required to manage the energy storage process dynamics within the battery. Battery life prediction contributes to the consistent and efficient operation of battery-powered devices. This research presents battery charging monitoring using Nodered. Apart from that, the battery charging feature uses a cut-off concept. The cut off on the battery is to prevent the battery from over-discharging which can damage the battery and shorten its lifespan. This research carried out validation using 3 case studies on battery charging. Validation of measurements uses a comparison between the INA 219 sensor and a multimeter. From experiments, current testing from 3 case studies, it was found that the average difference in current sensor error was 0.19%.

Abstract

Kerusakan lingkungan kini telah menyebar dan menjadi isu global, padahal dulunya dianggap sebagai permasalahan lokal dalam suatu negara. munculnya permasalahan lingkungan yang sebagian besar disebabkan oleh aktivitas manusia. Akibat kepedulian manusia terhadap lingkungan, residu tersebut mulai hilang. Oleh karena itu, kesadaran lingkungan perlu ditanamkan sejak dini. Karakter Salah satu cara sekolah dasar mengajarkan tanggung jawab terhadap lingkungan adalah melalui kelas sains. Tujuan Tujuan dari penelitian ini adalah untuk menggunakan pengajaran sains untuk membantu siswa sekolah dasar mengembangkan sikap sadar lingkungan. Penelitian ini menggunakan metode kualitatif. Tinjauan literatur dan dokumentasi digunakan untuk mengumpulkan data. Reduksi data, visualisasi data, dan penarikan kesimpulan/verifikasi merupakan metode yang digunakan untuk mengkaji data, yang kemudian disajikan kembali melalui pembahasan deskriptif. Studi ini menunjukkan bahwa menciptakan kurikulum ilmiah yang berpusat pada siswa dapat membantu siswa mengembangkan karakter sadar lingkungan. Siswa mendapat kesempatan untuk terlibat langsung dengan lingkungan melalui pendidikan sains. Guru dapat menerapkan berbagai model pembelajaran, antara lain Problem Based Learning (PBL), Project Based Learning (PjBL), Contextual Teaching and Learning (CTL), dan Outdoor Methods Learning, untuk membantu siswa mengembangkan karakter sadar lingkungan. Sumber daya pengajaran dan media pendidikan juga sangat penting dalam membantu anak mengembangkan karakter welas asih.
