Abstract

The purpose of this study is to determine whether there is influence of the number of cigarettes smoked per day against Lung Cancer at the School of Economics student Bali International Institute of Tourism Management (STIE - BITTM) Sahid. After analyzing gradually acquired sig . = 0.403 > 0.05 so that Ho is accepted in other words , a variable number of cigarettes smoked per day did not significantly influence the lung cancer illness among students . Obtained an average value of covariates (which is used as a predictor ) is 5.167 . This value means that both male and female students , the average cigarette rod 5 a day , the students in this study were categorized as light smokers because smoking less than 10 cigarettes per day . In other words they are in the maintenance stage of smoking . For students , smoking is one of self-regulation (self - preparatory ) , smoking was done to obtain unpleasant physiological effects . Based on Plot Survival Function at mean of covariates obtained survival rate (healthy) decreases student active smokers among female respondents in week 7 and men at week 9 through week 12 . This is consistent with the results Plot Hazard Function at Mean of covariates where possible dangers for female respondents lung disease appear after 7th week and continue to increase until week 11 .

Abstract

Piutang adalah klaim terhadap aset seperti uang, barang, atau jasa yang harus diterima dari pelanggan. Terkadang, piutang ini tidak dapat ditagihkan karena berbagai alasan, seperti ketidakmampuan atau ketidakmauan pelanggan untuk melunasi kewajibannya kepada perusahaan. Oleh karena itu, pengendalian internal terhadap piutang sangat penting. Pengelolaan yang tepat terhadap piutang memainkan peran kunci dalam perusahaan, terutama dalam hal kebijakan pemberian kredit. Salah satu contoh adalah Hotel Alila Seminyak, sebuah hotel bintang lima yang terletak di Jl. Petitenget No.9, Seminyak, Kec. Kuta Utara, Kabupaten Badung, Bali. Hotel ini menerapkan kebijakan kredit untuk penggunaan jasa kamar dan fasilitas lainnya. Oleh karena itu, penelitian ini bertujuan untuk mengevaluasi efektivitas pengendalian internal piutang di Hotel Alila Seminyak dalam mengurangi risiko piutang yang tidak dapat ditagih. Penelitian ini mengadopsi metode kualitatif yang menggunakan analisis deskriptif, di mana data dikumpulkan melalui wawancara dan observasi di Hotel Alila Seminyak. Teknik analisis data yang diterapkan adalah analisis deskriptif. Alila Seminyak sudah menerapkan beberapa sub-komponen dari lima komponen pengendalian internal piutang dengan baik. Namun masih terdapat beberapa sub-komponen yang belum diterapkan secara optimal dari prinsip kerangka kerja pengendalian internal Committee of Sponsoring Organizations of The Treadway Commision (COSO). Hasil pada penelitian menunjukkan bahwa sistem pengendalian internal atas piutang memerlukan adanya account receivable, penerpan credit limit, melakukan meeting dengan Finance Departement, serta pemberian sanksi berupa denda pada travel agent untuk mempertegas tindakan yuridis.

Abstract

Tourism planning, infrastructure growth, and economic stability. This study presents an extensive comparative evaluation of Random Forest (RF), Extreme Gradient Boosting (XGBoost), Long Short-Term Memory (LSTM), and a novel Hybrid RF-XGBoost model in the prediction of monthly international tourist arrivals. A full time series dataset of a ten-year period (2014–2024) from the Central Bureau of Statistics of Bali was used for training and testing the models. Hyperparameter optimization using Grid Search with cross-validation (Grid Search CV) was used for all the machine learning models to obtain best predictive performance. Two robust metrics, Root Mean Squared Error (RMSE) and Mean Absolute Percentage Error (MAPE), were used to assess forecasting accuracy. Results show that the Random Forest model outperforms all competitors with lowest RMSE (41,772.68) and MAPE (6.30%), indicating high forecasting precision and robustness, especially during structural breaks such as the COVID-19 pandemic. The hybrid model also performs well, with LSTM indicating higher error rates, illustrating its shortcomings on small-to-medium-scale tourism time series. Besides, the study provides six-month ahead predictions (January–June 2025) with 95% prediction intervals, showing an ongoing trend of recovery. The findings affirm the superiority of bagging-based ensemble methods over polynomial-based methods in capturing nonlinearity, seasonality, and exogenous shocks in tourist demand. The study plugs the growing amount of data-driven tourism analytics by offering a reproducible, high-precision forecasting model for developing countries and seasonally driven destinations.
