Abstract

Pemanfaatan teknologi di era globalisasi saat ini sudah menjadi prioritas utama bagi manusia baik dari segi kemudahan maupun efisiensi waktu dalam melakukan berbagai aktivitas. Dengan adanya kemajuan teknologi yang semakin canggih, manusia mengharapkan sebuah perangkat teknologi untuk memudahkan pekerjaan sehari-hari misalnya penyiraman tanaman otomatis. Dalam penelitian ini dikembangkan water pump otomatis dengan menggunakan dua Sensor Soil Moisture YL 69 sehingga diperoleh keakuratan pada nilai kelembaban di dalam tanah dan di permukaan tanah. Rata-rata data yang diambil perharinya adalah 3 jam, dimana pengukuran dilakukan setiap 2 detik sekali maka jumlah data kurang lebih adalah 5400 data per hari. Selain itu, penelitian ini sudah berbasis web sehingga bisa diakses secara dalam jaringan (daring) jika terkoneksi dengan internet dan dapat langsung mengunduh data grafik dalam format JPEG, PNG, PDF, dan SVG juga dapat dicetak dan tabel dapat diunduh dalam format CSV, Excel, dan PDF juga dapat dicetak.

Abstract

Composite is a combination of several or more different materials, which produce better properties than their composition properties. The process of making composites can be done with a pressing method which can reduce voids. This pressing method can use a hydraulic press machine. This study aims to design and analyze a hydraulic press machine with a capacity of 20 tons. The design process begins with designing a 3D model using Solidwork Software. Numerical simulation using the finite element method by providing several variations in pressure loads ranging from 5-20 MPa. The results of the analysis show that the maximum von Mises stress is 79.70 MPa with a maximum deformation of 0.0176 mm and the smallest value of safety factor is 2.595. Based on these results, the press machine design is claimed to be safe to operate.

Abstract

Artikel ini akan mendiskusikan evaluasi kebijakan larangan pembuangan sampah di Sungai Karang Mumus. Pendekatan kualitatif digunakan sebgaai metode penelitian dan dianalisis dengan model analisis data interaktif. Pengumpulan data dilakukan melalui observasi, wawancara, dan studi literatur. Temuan penelitian menunjukkan bahwa pelaksanaan kebijakan belum maksimal dimana dari indikator sosialisasi belum efektif dan merata serta masyarakat belum mengetahui sanksi jika melanggar. Pengawasan tidak berjalan maksimal dan tidak terjadwal. Penindakan juga hanya memberikan sanksi yang ringan.Kata kunci: kebijakan, evaluasi, sampah, larangan, sungai

Abstract

Drop-foot is an inability to lift the foot when walking due to muscle weakness or paralysis. One of the common rehabilitation aids for stroke sufferers with drop-foot is Ankle Foot Orthosis (AFO). This tool serves as a stabilizer for road pattern balance. However, most of the AFO used is passive, so it doesn't help users run properly. Therefore, an active AFO system has been designed as a rehabilitation aid. This AFO is designed with motor control from myoelectric feedback signal (EMG) and also a semi-dynamic ankle joint so that it is more flexible to help the user when stepping. The AFO movement set of to the foot's position in Dorsi and Plantarflexion conditions based on the EMG parameter received by the control unit. Then, the angle sensor standardizes the user's ankle position so that the foot fits the states that have set. This design uses the fuzzy logic method, which functions to control the rotation of the servo motor. The interface system is for monitoring parameters. In this design, pressure sensors (force), EMG, and angle sensors transmitted wirelessly to a computer are used for data analysis under the needs of real-time statistical data processing.

Abstract

Business competition in the palm oil industry causes customer loyalty to be an important factor to maintain business continuity. The authors examine the factors that influence customer purchase intent and its relationship with customer loyalty. The researcher sees the influence of the relationship between Product Quality, Goods Price and Service Quality and the influence of moderation factors from the Payment System on Customer Purchase Intention and Influence Customer Loyalty. In the results of this study, Product Quality and Quality Perceived by Buyers Affect Customer Purchase Intentions. The Payment System strengthens Product Quality to the Customer's buying interest, Purchase intention affects loyalty. While Product Prices and Product Services do not affect Customer Purchase Intention and Ease of Payment is unable to moderate Product and Product Service Prices against Purchase Intentions. This study discusses the relationship between the influence of payment systems on buying interest and customer loyalty in the palm oil industry. This article will contribute literature in palm oil marketing and will simultaneously help the company to maintain customer loyalty.

Abstract

The increasing percentage of e-commerce users each year, accompanied by the growing convenience of online shopping, is considered to have led to the phenomenon of impulse buying tendency, especially in the context of e-commerce usage. This study aims to discuss the occurrence of impulse buying tendency in Indonesia based on the perspectives of the Elaboration Likelihood Model and Regulatory Focus Theory, using information transparency to represent the central route, celebrity endorsers to represent the peripheral route, and regulatory focus as a moderating variable. The research is focused on Shopee, which is one of the most popular e-commerce in Indonesia, therefore the population is Shopee users in Indonesia. The purposive sampling technique was used with a total of 445 respondents, which were taken from 5 top universities in Indonesia. The results of this study indicate that both information transparency and celebrity endorsers have a significant influence on impulse buying tendencies. Furthermore, regulatory focus is found to be a significant moderating variable of the relationship between information transparency and impulse buying tendency, however, there is no significant effect found on the moderating role of regulatory focus in the relationship between celebrity endorsers and impulse buying tendency. Referring to this, it is hoped that the Shopee e-commerce company can provide information according to the needs of consumers and consider the selection of supporting celebrities in accordance with the products or brands offered.

Abstract

Concentrated Photovoltaic (CPV) technology offers the potential to enhance solar energy conversion by utilizing light focusing technology to increase the solar irradiation flux received by photovoltaic cells. On the other hand, as the solar energy density increases on a PV cell, the surface temperature of the PV also rises, which results in decreased energy conversion efficiency and the possibility of thermal fatigue. Therefore, a reliable cooling system is required for CPV. This study aims to evaluate the performance of a two-phase flow heat sink with ethyl acetate (C4H8O2) as the working fluid, which has a low boiling point and high heat of vaporization, making it quite effective for heat transfer. The method used is numerical simulation using Computational Fluid Dynamics (CFD) software. The simulation results show that the heat sink heat transfer effectiveness is 86.03%, with a thermal resistance value of 0.0073 . The highest temperature on the solid part is 105  showing an increasing trend but not significantly, while the average fluid temperature tends to remain constant at 55 . This indicates that the evaporation process is able to maintain the heatsink temperature at stable level.
