No full textIn the cigarette paper industry, pallet packaging plays a crucial role in the supply chain. It helps protect cigarette paper from physical damage and environmental factors during transportation and storage. PT BM faces several challenges, one of which is inefficiency in inventory management, leading to unnecessary costs in production and distribution processes. This study applies the Economic Order Quantity (EOQ) method to determine the optimal order quantity of raw materials, ensuring a smooth production process. The calculation results show that implementing the EOQ method leads to more efficient total inventory costs compared to the company\u27s previous ordering policy. For local pallets, the optimal order quantity changed from 3,600 sets ordered 12 times per year (costing Rp 43,200,000.00) to 514,208 sets ordered only 3 times per year (costing Rp 10,800,000.00). A similar improvement was observed for export pallets, where the order quantity changed from 3,600 sets ordered 24 times per year (costing Rp 52,200,000.00) to 338,327 sets ordered only 3 times per year (costing Rp 6,525,000.00). Additionally, the total inventory cost using the EOQ method was recorded at Rp 38,333,333.33 for local pallets and Rp 36,912,500.00 for export pallets.

No full textAbstrak
Penelitian ini menganalisis penerimaan vaksin booster COVID-19 serta willingness to pay (WTP) di masyarakat Kota Bandar Lampung dengan pendekatan Health Belief Model (HBM). Studi ini menggunakan metode survei cross-sectional terhadap 400 responden berusia ≥18 tahun yang belum menerima vaksin booster, selama Maret–Mei 2023. Data dikumpulkan melalui kuesioner daring dan dianalisis menggunakan SEM-PLS serta metode deskriptif untuk WTP. Hasil penelitian menunjukkan bahwa komponen utama HBM yang secara signifikan mempengaruhi penerimaan vaksin booster adalah perceived benefits, self efficacy, cues to action, dan perceived barriers. Sementara itu, perceived susceptibility dan perceived severity tidak ditemukan sebagai prediktor kuat dalam model. Faktor demografi seperti usia, pendidikan, dan pendapatan berpengaruh signifikan terhadap konstruk HBM dan sikap terhadap vaksin. WTP masyarakat untuk vaksin booster tergolong rendah: hanya 26,75% responden bersedia membayar dengan rata-rata nilai sebesar Rp 130.794 per dosis, mayoritas mengharapkan program tetap gratis atau disubsidi pemerintah. Temuan ini menunjukkan bahwa strategi peningkatan cakupan vaksinasi booster perlu berfokus pada edukasi manfaat konkret, penguatan motivasi dan kepercayaan diri masyarakat, serta pengurangan hambatan ekonomi dan logistik. Pemerintah disarankan mempertahankan subsidi vaksin untuk meningkatkan partisipasi booster di masa transisi pandemi.

This study analyzes the acceptance of the COVID-19 booster vaccine and the public’s willingness to pay (WTP) in Bandar Lampung City using the Health Belief Model (HBM). A cross-sectional survey was conducted among 400 respondents aged ≥18 years who had not received a booster dose during March–May 2023. Data were collected through an online questionnaire and analyzed using SEM-PLS and descriptive methods for the WTP component. The findings indicate that the key HBM constructs significantly influencing booster vaccine acceptance are perceived benefits, self-efficacy, cues to action, and perceived barriers, while perceived susceptibility and perceived severity do not serve as strong predictors. Demographic factors such as age, education, and income significantly affect HBM constructs and attitudes toward vaccination. Public WTP was relatively low, with only 26.75% of respondents willing to pay and an average (mean) WTP of IDR 130,794 per dose, while most respondents expected the booster program to remain free or government-subsidized. These results highlight the need for strategies that emphasize concrete benefits, strengthen motivation and self-confidence, and reduce economic and logistical barriers. It is recommended that the government maintain vaccine subsidies to enhance booster uptake during the pandemic transition period.

No full textAbstrak
Penelitian ini mengkaji perluasan legal standing dalam permohonan pembubaran partai politik di Mahkamah Konstitusi Indonesia. Kerangka hukum saat ini yang secara eksklusif memberikan hak kepada pemerintah untuk mengajukan permohonan pembubaran partai politik menciptakan tantangan konstitusional yang signifikan. Menggunakan pendekatan yuridis normatif dengan metode kualitatif-deskriptif, penelitian ini menganalisis urgensi perluasan subjek dan alasan pembubaran partai politik. Penelitian mengeksplorasi bagaimana mekanisme yang membatasi saat ini menghambat partisipasi warga negara dalam pengawasan demokratis dan berpotensi mengancam prinsip kedaulatan rakyat dan akuntabilitas hukum. Dengan membandingkan praktik demokrasi internasional dan menganalisis prinsip-prinsip konstitusional Indonesia, penelitian ini mengusulkan model perluasan legal standing yang mencakup warga negara, organisasi masyarakat sipil, badan pengawas pemilu, dan lembaga anti-korupsi. Model yang diusulkan bertujuan memperkuat mekanisme checks and balances demokrasi, meningkatkan akuntabilitas partai politik, dan memastikan partai politik beroperasi dalam batas-batas konstitusi dan hukum. Penelitian menyimpulkan bahwa perluasan permohonan pembubaran partai politik merupakan kebutuhan konstitusional untuk memperkuat demokrasi dan negara hukum di Indonesia.
