Abstract

In 2019, the number of conventional vehicles in Indonesia reached 133,617,012 units, dominated by motorcycles of 112,771,136 units and passenger cars of 15,592,419 units. The high number of conventional motorcycle users can increase the number of pollutants and combustion emissions in the environment. This condition has encouraged the transition to a sustainable transport system that will be needed for decades to come, especially for the electric motorcycle to resolve the issue. This research aims to predict and estimate the market share of electric motorcycles by considering life cycle cost per kilometer. System dynamics simulations are developed to model the adoption-diffusion of electric motorcycles in Indonesia. This model has four main modules: an electric motorcycle module, a conventional motorcycle module, an economy module, and a consumer market module. This model shows a positive trend of EM market share from 2021-2030, with the market share value of EM is 0,411 in 2030. The development of retail price subsidy and electricity price scenarios is also carried out to determine the right policies to accelerate the adoption-diffusion process. Based on the scenario, the provision of retail price subsidy and a decrease in electricity price can increase the value of the EM Market Share.

Abstract

Electric buses are increasingly promoted as a sustainable public transportation solution in Indonesia's urban areas, yet their adoption rate from the user perspective remains relatively limited. This study aims to develop a user-oriented conceptual framework to explain the adoption process of electric bus services within Indonesia's urban public transportation system. The study employs a systematic literature review approach following PRISMA guidelines, analysing scientific articles published from 2015 to 2025, with a total of 30 studies examined in depth. Through content analysis, 13 main constructs were identified that integrate behavioral, psychological, technology acceptance, service attribute, and risk perception dimensions, based on the Technology Acceptance Model and the Theory of Planned Behaviour. Based on this synthesis, this study proposes a process-based conceptual framework that maps the stages of electric bus adoption, from evaluating service attributes to actual usage. To strengthen its empirical applicability, the constructs were operationalized into measurable questionnaire indicators adapted from prior studies and supported through expert review and pilot testing with electric bus users. This framework is positioned as an exploratory model to support the identification of factor structures and serve as a basis for empirical Research and the formulation of sustainable public transportation policies in Indonesia.

Abstract

The need for housing for Indonesian people is increasing yearly due to the high population growth rate. This fact can gradually trigger global warming. There is a need for intervention in the residential sector to minimize the resulting negative impacts by developing a green building concept. This study uses an extended Theory of Planned Behavior to identify the factors influencing purchase intention and willingness to pay for green housing (GH) in the Jabodetabek community. The study collected 347 valid responses through a survey with a purposive sampling method and used structural equation modeling to test the hypotheses. The factors raised in this study are attitudes, perceived behavioral control, subjective norms, environmental concern, subjective knowledge, policy, perceived risks, green communication, green purchase intentions (GPI), and willingness to pay (WTP). This research proves that attitude, policy, and subjective knowledge factors significantly directly affect GPI. Meanwhile, environ­mental concerns and subjective knowledge can also significantly and indirectly affect GPI. This study also proves a significant influence between GPI and WTP for GH in the Jabodetabek community. Perceived risk has a significant negative impact on the GPI. Additionally, developers can employ a strategy that combines attitude, subjective knowledge, and environmental concern to design programs that address consumers' cognitive and affective aspects. The government can also play a role in promoting the use of GH through incentives related to green construction.

Abstract

The intense competition in the food industry in Central Java requires business actors to understand the marketing factors that influence consumer behavior. The lack of understanding regarding the impact of each element of the marketing mix (4P) on consumer attitudes and purchase intentions forms the background of this study. This research aims to analyze the influence of the 4P marketing mix elements—product, price, place, and promotion—on consumer attitudes and purchase intentions toward food products in Central Java. Using a quantitative approach with the PLS-SEM method, data were collected from 500 respondents aged 15–60 through an online survey distributed via social media. The analysis results indicate that only two relationships were statistically significant. These findings suggest that in the context of the food industry in Central Java, product quality and the development of consumer attitudes are the primary factors influencing purchase intention. This study contributes to a deeper understanding of local consumer behavior and serves as a strategic reference for business actors in formulating more effective marketing strategies. Keywords: β coefficient, consumer attitude, Central Java market, marketing mix (4P), online survey.

Abstract

Peramalan data penjualan berperan penting dalam optimisasi persediaan produk pada bisnis retail. Apotek adalah satu bentuk bisnis retail yang menjual sediaan farmasi (obat, bahan obat, obat tradisional dan kosmetika), alat kesehatan, dan bahan medis habis pakai. Apotek Suganda yang berlokasi di Kabupaten Sragen, melakukan penentuan rencana pengisian kembali (pembelian) sediaan farmasi dengan manual berbasis kebiasaan semata. Mekanisme tersebut terkadang menyebabkan terjadinya kekurangan persediaan obat. Oleh karena itu, untuk memperbaiki perencanaan pembelian, perlu dilakukan peramalan permintaan sediaan farmasi. Beberapa metode dujikan untuk melakukan peramalan permintaan, salah satunya menggunakan metode Long Short-term Memory (LSTM), yakni suatu metode berbasis machine learning. Bersama dengan métode-metode lainya yakni Least Square, Single exponential Smoothing, Double exponential Smoothing, Triple Exponential Smoothing, Winter Exponential Smoothing, Weight Moving Average, dan ARIMA, peramalan penjualan sediaan farmasi dilakukan. Hasil pengujian menunjukkan bahwa peramalan penjualan sediaan farmasi secara mingguan yang menggunakan LSTM memiliki Mean Absolute Percentage Error (MAPE) yang paling rendah dibanding metode lainnya. Dengan demikian, implementasi peramalan penjualan berbasis machine learning perlu dimanfaatkan, salah satunya dengan membuat modul peramalan untuk diintegrasikan dengan aplikasi penjualan yang dimiliki oleh apotek tersebut.

Abstract

Dalam era digitalisasi saat ini, arus informasi sangat mudah dan cepat untuk didapatkan. Hal tersebut terlihat dari banyaknya media yang memberikan akses mengenai berita aktual yang terjadi, baik tingkat global hingga internasional. Salah satu media yang digunakan untuk mengakses berita adalah media cetak (koran). Namun dengan adanya digitalisasi menyebabkan permintaan koran fluktuatif menurun dan tingkat retur atau pengembalian koran dari agen cukup tinggi. Hal tersebut dapat merugikan perusahaan. Maka perlu adanya metode peramalan jumlah permintaan koran cetak dengan tingkat kesalahan terkecil agar dapat mengurangi kerugian perusahaan akibat pengembalian koran. Metode yang digunakan adalah metode trend line analysis dan metode jaringan syaraf tiruan backpropagation. Data yang digunakan adalah data actual demand, hasil penjualan, harga penjualan dan stok dari bulan Januari 2020 hingga Januari 2021. Proses perhitungan menggunakan Microsoft Excel dan Matlab. Selain itu, pemilihan metode yang terbaik didapatkan dengan membandingkan nilai MSE terkecil. Berdasarkan perbandingan nilai MSE yang dilakukan, didapatkan bahwa nilai MSE dengan metode trend line analysis sebesar 4.39. Sedangkan, nilai MSE dengan metode jaringan syaraf tiruan backpropagation sebesar 0,0107. Oleh karena itu, metode peramalan yang terbaik untuk melakukan peramalan jumlah permintaan koran cetak PT. XYZ adalah metode jaringan syaraf tiruan backpropagation.
