Abstract

The arrangement is a rewriting work of an existing composition with the addition of new material or the completion of the design of a composition.Based on the observation of the musical works, rarely people who play and arranged a song“It Is Well With My Soul” using a guitar instrument in a quartet format. Many other formats play the arrangement of this song, played in pianos, strings, choirs, guitar solos, and orchestras, and in a quartet guitar format is rarely played, that is the reason researchers interested conduct this research. It is well with my soul is a song from Hymn of praise, the lyrics of this song were created based on Horatio G Spafford (1828) experience.Whose then melody was created by Phillip Paul Bliss (1838) was a leader of compliments and composers from America. Philip was impressed by the lyrics that had been written by spafford. And then philip created a melody based on his life experience, that song called “it is well with my soul”.To arranged a song we must understand about melody, harmony, interval, rhythm, musical form, and instrument character to be used in the arrangement of songs that we will arrange to become a new arrangement. Before arranging a song we must choose the music format to be used, In this arrangement will use Quartet guitar format as a musical instrument to play the song arrangement, The guitar quartet is a category of similar ensembles using classical guitar instruments and played by four guitar players. In the methodology of creation there are three stages before we arranged a song. The first stage is to create the idea of making arrangements, the second stage is to design the arrangement of songs, the third stage is the implementation, displaying the work of the arrangement. Overall from this arrangement that have been made, there is something unique, that the original melody is not always on the first guitar, but also played by other guitar players, to change the outgoing sound dimension when played. In the new arrangement the song is divided into three variations, Variation I starts from the bar 31-46, Variation II is starts from the bar 56-97 and Variation III starts from the bar 98-147.

Abstract

This research delves into the challenges faced by a hospitality IT vendor providing services to a diverse clientele in Indonesia. The vendor, relying on profits from clients for operational and developmental activities, needs help with the billing process. The complexities arise from various payment schemes, including full payments and installments, coupled with the annual requirement for clients to purchase a maintenance key for continued system access. The existing transaction process experiences delays due to difficulties searching for invoice data among numerous clients with varying payment times. These delays hinder the timely collection of subsequent payments, resulting in receivables and potential disruptions to the vendor's cash flow for operational and developmental costs. Traditional bill recording methods compound the problem with inaccuracies and data retrieval challenges The findings of this research is a web-based application developed through the SDLC prototyping model to address these issues. The application, evaluated through User Acceptance Testing (UAT), successfully overcame the challenges. The results indicate that the application efficiently manages invoice data, facilitates timely payments, and enhances overall accuracy in data processing. In conclusion, the web-based application is an optimal solution, resolving invoice management issues and streamlining processes for the hospitality IT vendor.

Abstract

Penelitian ini mengeksplorasi penerapan algoritma Support Vector Machine (SVM) dalam Text Mining untuk analisis sentimen sektor pariwisata di Indonesia, menggunakan data dari platform Twitter. Data dikumpulkan melalui API Twitter dan diproses melalui tahapan prapemrosesan teks, termasuk tokenisasi, normalisasi, penghapusan stopword, dan stemming, untuk memastikan kesiapan data dalam analisis. Model SVM diuji dengan tiga kernel berbeda—linear, radial basis function (RBF), dan sigmoid—serta menggunakan rasio data latih-uji 7:3 dan 8:2. Hasil menunjukkan bahwa kernel linear dengan rasio 7:3 menghasilkan kinerja terbaik dengan akurasi 92,89%, precision 92%, recall 74%, dan F1-score 81%. Evaluasi berdasarkan kelas sentimen menunjukkan performa tinggi pada sentimen positif (F1-score 96%) tetapi moderat pada kelas netral (F1-score 67%), mencerminkan pengaruh ketidakseimbangan data. Penelitian ini memberikan kontribusi signifikan dalam mendukung pengambilan keputusan berbasis data untuk pengembangan sektor pariwisata. Temuan ini memungkinkan pengelola destinasi wisata untuk memahami opini wisatawan secara otomatis, menyusun strategi promosi yang lebih efektif, serta meningkatkan kualitas layanan. Dengan menerapkan analisis sentimen berbasis SVM, penelitian ini mendukung pengelolaan pariwisata berbasis data untuk meningkatkan daya saing destinasi wisata di Indonesia. Penelitian lanjutan disarankan untuk mengatasi ketidakseimbangan data melalui teknik resampling atau penerapan algoritma alternatif seperti deep learning, guna meningkatkan akurasi klasifikasi sentimen yang lebih kompleks. Dengan demikian, penelitian ini menjadi langkah strategis dalam memanfaatkan teknologi analitik untuk pengelolaan pariwisata yang lebih inovatif.

Abstract

A reliable control system is essential for the operation of a wheeled robot. A castor wheel is a robotic control device that enables the wheeled robot to navigate to various positions and orientations. One implementation method employs a servo motor to adjust the orientation of the castor wheel to a specific driving angle. The mechanism is robust, cost-effective, and simple to produce. This work demonstrates the development of a castor-wheel-based control mechanism utilizing a servo motor and the pure pursuit algorithm to determine the driving angle. The designated wheeled robot employs a BLDC motor as the primary actuator for its two main wheels. An experiment has been performed to assess the proposed control mechanism. The proposed control system achieved a position error of 0.228 m in the Y direction minimally and less than 1 m position error globally. This study presents mechanical, electrical, and software components.

Abstract

A comfortable home is one of the basic human needs, namely the need for shelter. However, not only is it comfortable, a residential house must also be designed and calculated for its structural needs so that it is safe from the loads acting on the house, including loads due to loads inside the house (dead load, superimposed dead load, live load) and earthquake loads. Therefore, the aim of this Abdimas activity is to calculate the structure in accordance with the provisions based on the Indonesian National Standard (SNI) for three-story houses in the Jepara area. Partner as the architect has carried out interior and architectural designs, but has not been able to check the structural design needs of the house. Therefore, expert assistance is needed to calculate the structure of the house so that it meets the strength, serviceability, and comfort requirements based on applicable regulations. The structure of the Jepara House is quite complex because there is a mezzanine floor and quite a lot of floor leveling variations. Apart from that, the ground floor is also planned to be used as a shop, which means the load is quite large. The scope of this Abdimas includes structural calculations using an open frame system, foundation planning by interpreting soil data, creating construction drawings for use in the field, as well as coordinating problems that occur in the field. Currently, the structural drawings have been completely completed and have been given to Partners to work on. Meanwhile, construction is still ongoing and is expected to be completed around November. ABSTRAK Rumah tinggal yang nyaman merupakan salah satu kebutuhan pokok manusia, yaitu kebutuhan akan papan. Namun tidak hanya nyaman, rumah tinggal juga harus didesain dan dihitung untuk kebutuhan strukturnya agar aman terhadap beban yang bekerja pada rumah tersebut, di antaranya beban akibat muatan-muatan di dalam rumah (dead load, superimposed dead load, live load) dan beban gempa. Maka dari itu tujuan dalam kegiatan Abdimas ini adalah perhitungan struktur sesuai dengan ketentuan berdasarkan Standar Nasional Indonesia (SNI) untuk rumah tiga lantai di daerah Jepara. Mitra selaku arsitek telah melakukan desain untuk interior dan arsitektur, namun belum dapat mengecek untuk kebutuhan desain struktur rumah tersebut. Maka dari itu diperlukan bantuan tenaga ahli untuk melakukan perhitungan struktur rumah tersebut agar memenuhi syarat kekuatan, ketahanan, dan kenyamanan berdasarkan peraturan yang berlaku. Struktur Rumah Jepara ini cukup kompleks karena terdapat lantai mezzanine dan variasi levelling lantai yang cukup banyak. Selain itu di lantai dasar juga direncanakan agar dapat difungsikan sebagai toko yang berarti bebannya cukup besar. Cakupan Abdimas ini meliputi perhitungan struktur dengan sistem open frame, perencanaan pondasi dengan membaca data tanah, membuat gambar kerja untuk digunakan di lapangan, serta koordinasi terhadap kendala-kendala yang terjadi di lapangan. Saat ini, gambar struktur telah selesai sepenuhnya dan telah diberikan kepada Mitra untuk dikerjakan. Sementara itu, pembangunan masih sedang berjalan dan diperkirakan akan selesai di sekitar bulan November

Abstract

Marketing is a very important strategy to introduce products and attract consumers, especially in the fashion sector which continues to develop following trends and lifestyles. Irian Supermarket located in Tanjung Morawa also provides fashion products, but is facing a decline in sales because it is unable to compete with specialty stores or online shopping platforms that offer more choices, more affordable prices, and products that are more in line with trend developments. Some of the reasons for the low consumer buying interest include relatively expensive prices, less attractive promotions, and product quality that has not met expectations. To increase the attractiveness of fashion products, this supermarket needs to review its pricing strategy, improve its promotional approach, and provide products with more modern quality and design. This study covers all visitors to Irian Supermarket Tanjung Morawa as the population, although the exact number is not clearly known or tends to be biased. Therefore, the sampling technique uses the Lemeshow formula, which is appropriate when the population size is not known for certain, so that one hundred people are determined as the research sample. The sampling method used is accidental sampling, which is the random selection of respondents based on who is willing and available when the research is conducted. The results of the study indicate that partially, price has a significant negative effect on purchasing decisions. Promotion has a significant effect on purchasing decisions partially. Product quality also shows a significant effect partially on purchasing decisions. Together, the variables price, promotion, and product quality have a significant effect on consumer purchasing decisions.

Abstract

Rice production in East Kalimantan Province during 2023 reached around 215,290 tons/year of milled dry grain. Rice is one of the main agricultural products that produce waste in the form of rice husks. Rice husk is stillNot well utilized so that it only becomes a pile of agricultural waste. Rice husk ash contains compounds that can be used as catalyst support, including SiO2. This study aims to determine the effect of rice husk ash catalyst from the KOH impregnation method as a catalyst for making biodiesel from conventional palm oil. Transesterification was conducted on palm oil with the ratio of catalyst mass to oil volume (10%, 15%, 20%). Biodiesel production from palm oil using KOH impregnated catalyst with 2N concentration and 20% catalyst concentration produced the highest yield of 86.3%. Viscosity and density of the results obtained meet the standards.
