Abstract

Abstrak - Rental mobil dan motor merupakan layanan penting bagi masyarakat, terutama bagi mereka yang membutuhkan transportasi di daerah tertentu. Namun, masyarakat sering menghadapi kesulitan dalam mengakses informasi mengenai lokasi dan layanan rental mobil serta motor, yang mengharuskan mereka mengandalkan sumber informasi informal atau melakukan kunjungan langsung, sehingga mengakibatkan pemborosan waktu dan tenaga. Penelitian ini bertujuan untuk mengembangkan aplikasi berbasis WebGIS yang memfasilitasi pencarian rental mobil dan motor di Kota Lhokseumawe. Aplikasi ini dirancang untuk memberikan informasi yang akurat dan detail mengenai lokasi layanan rental tersebut, dengan tujuan mempermudah dan mempercepat akses informasi bagi masyarakat. Dalam proses pengembangan, aplikasi ini menggunakan bahasa pemrograman PHP, HTML, JavaScript, dan CSS, serta memanfaatkan software MySQL MariaDB untuk penyimpanan basis data. Peta Leaflet digunakan untuk visualisasi geografis yang memungkinkan pengguna melihat lokasi rental mobil dan motor secara interaktif. Metode penelitian melibatkan perancangan basis data menggunakan Entity Relationship Diagram (ERD), pengembangan aplikasi, serta evaluasi dan pengujian fungsionalitas aplikasi. Hasil penelitian menunjukkan bahwa aplikasi ini efektif dalam menyediakan informasi lokasi secara cepat, efisien, dan akurat. Aplikasi ini menawarkan solusi yang signifikan bagi masyarakat dalam mencari layanan rental mobil dan motor di Kota Lhokseumawe, serta berfungsi sebagai alat informasi yang berguna bagi pengelola bisnis rental.Kata kunci: Aplikasi Pencarian, Rental Mobil dan Motor, WebGIS Abstract - Car and motorbike rental services are essential for people, especially those in need of transportation in specific areas. However, the public often faces challenges in accessing information regarding the locations and services of car and motorbike rentals, frequently relying on informal sources of information or making direct visits, which results in wasted time and effort. This research aims to develop a WebGIS-based application to facilitate the search for car and motorbike rentals in Lhokseumawe City. The application was designed to provide accurate and detailed information about the locations of these rental services, with the goal of making information access easier and faster for the public. The development process utilizes programming languages such as PHP, HTML, JavaScript, and CSS, along with MySQL MariaDB software for database storage. Leaflet Maps are employed for geographic visualization, allowing users to interactively view rental car and motorbike locations. The research methodology involves database design using an Entity-Relationship Diagram (ERD), application development, and the evaluation and testing of the application's functionality. The results of the study indicate that this application is effective in providing fast, efficient, and accurate location information. This application offers a significant solution for the public in finding car and motorbike rental services in Lhokseumawe City and serves as a useful informational tool for rental business managers.Keywords: Application, Car and Motorbike Rental, WebGIS

Abstract

The need for fertilizers has significantly increased due to the expanding global population and the mounting pressure on agricultural systems to increase food production. Fertilizers are essential in upgrading soil fertility and increasing crop productivity, making them indispensable in contemporary agriculture. Extensive usage of chemical fertilizers has led to environmental issues such as soil deterioration, water contamination, and the exhaustion of non-renewable resources like phosphate rock. Phosphorus, one of the essential macronutrients for plants, is a critical component of commercial fertilizers. Struvite, with its high phosphate content, presents a viable alternative to conventional fertilizers. Struvite (MgNH4PO46H2O) is a crystalline compound comprising magnesium, ammonium, and phosphate. Cow urine, which contains nitrogen, phosphate, and potassium, can serve as a nutrient source for plants. In the context of fertilizer production, bittern serves as a source of magnesium. This study investigated the production of struvite from cow urine and bittern using a precipitation technique. The study aimed to determine the optimal conditions for maximizing struvite production, focusing on the ratio of cow urine to bittern and the storage duration of cow urine. The research involved the preparation and characterization of raw materials, struvite synthesis, and the analysis of struvite characteristics. The optimal conditions were found to be a molar ratio of cow urine to bittern of 1:1 and a cow urine storage time of one week. UV-VIS spectrophotometry was utilized to analyze phosphate and ammonia contents, yielding optimal values of 72.417 mg/kg and 0.715 mg/kg, respectively. XRF analysis indicated a magnesium content of 26.000 mg/kg. SEM and XRD analyses revealed that the morphology of the struvite was orthorhombic at the optimum conditions. FTIR analysis was used to identify N-H, P-O, and water vibrations.

Abstract

This research investigated a Bismuth-based ceramic nanocomposite material with the stoichiometric composition Bi?.?Pb?.?Sr?Ca?Cu?O_y (abbreviated as B(P)SCCO-2223), synthesized via the solid-state reaction method. The fabrication process involved compound composition calculations and powder metallurgy using several high-purity oxide precursors, with bismuth oxide as the primary component. Heat treatment in the form of sintering was conducted at 846?°C for durations of 32 and 34 hours to examine its effects on the material’s physical properties. Scanning Electron Microscopy (SEM) analysis revealed layered grain structures with the presence of pores at grain boundaries. Energy Dispersive X-ray (EDX) analysis confirmed that the target 2:2:2:3 elemental ratio was achieved across all samples. X-ray Diffraction (XRD) analysis showed that the sample sintered for 34 hours exhibited the largest grain size of 48.07?nm. The holding time of 34 hours during the sintering process has provided sufficient opportunity for the crystal grains to grow larger. Scanning electron microscopy photos also show that longer sintering times make the empty space between the grains smaller because the crystal grains are closer together, followed by the pore size becoming smaller. This sample also demonstrated the highest oriented phase percentage (58.12%) and the lowest impurity level (6.05%). Mechanical properties, evaluated using Vickers microhardness testing, indicated that the 34-hour sintered sample had superior performance, with a Vickers hardness of 0.905?GPa, Young’s modulus of 74.2?GPa, yield strength of 0.301?GPa, fracture toughness of 5.17, surface energy of 0.18?J, and a brittleness index of 0.175. Overall, the study concluded that the physical properties of the ceramic nanocomposite improved with increased sintering duration.
