Abstract

Latar belakang penelitian ini adalah kurangnya pengetahuan pelaku UMKM dalam menghitung harga pokok produksi (HPP), yang berdampak pada ketidakakuratan penentuan harga jual dan daya saing produk. Hal ini menjadi tantangan bagi perguruan tinggi untuk memberikan solusi melalui pengabdian masyarakat. Tujuan penelitian adalah meningkatkan pemahaman pelaku UMKM, khususnya perempuan di Jawa Barat, tentang perhitungan HPP agar mereka dapat menentukan harga jual yang kompetitif. Metode yang digunakan adalah workshop kombinasi diskusi teori dan pelatihan praktis, mencakup penyampaian materi elemen HPP (biaya bahan baku, tenaga kerja langsung, dan overhead) serta pendampingan perhitungan sesuai konteks usaha peserta. Hasil penelitian menunjukkan peningkatan signifikan dalam pengetahuan peserta terkait perhitungan HPP, dengan antusiasme tinggi selama pelaksanaan kegiatan. Implikasi penelitian ini adalah perlunya pendampingan berkelanjutan untuk memperkuat kapasitas UMKM, tidak hanya dalam perhitungan HPP tetapi juga aspek akuntansi lainnya seperti pembukuan sederhana. Kegiatan ini juga mendukung Tujuan Pembangunan Berkelanjutan (SDGs) terkait pertumbuhan ekonomi inklusif dan pemberdayaan perempuan.

Abstract

Penelitian ini bertujuan untuk menyelidiki dampak leverage dan likuiditas terhadap return saham pada perusahaan perbankan yang terdaftar di Bursa Efek Indonesia (BEI) selama periode 2014-2022. Penelitian ini menggunakan metode deskriptif-analitis dengan analisis data panel. Data dikumpulkan melalui studi literatur dan dokumentasi laporan keuangan perusahaan perbankan publik. Hasil penelitian menunjukkan bahwa likuiditas memiliki pengaruh positif dan signifikan terhadap return saham, yang berarti bahwa likuiditas yang lebih tinggi pada bank cenderung menghasilkan return saham yang lebih tinggi. Di sisi lain, leverage ditemukan tidak memiliki pengaruh signifikan terhadap return saham selama periode yang diteliti. Hasil ini mendukung teori signaling, di mana likuiditas menjadi sinyal bagi investor dalam pengambilan keputusan investasi, sementara leverage tidak mempengaruhi harga saham secara signifikan. Penelitian ini menyimpulkan bahwa peningkatan pengelolaan likuiditas sangat penting untuk meningkatkan return saham di sektor perbankan. Namun, leverage tidak tampak sebagai faktor yang krusial bagi investor dalam membuat keputusan investasi di sektor ini. Temuan ini memiliki implikasi bagi investor dan pembuat kebijakan, yang menunjukkan bahwa likuiditas harus diprioritaskan dalam operasi perbankan untuk memastikan return yang stabil dan menarik bagi investor.

Abstract

This study investigates the integration of the Apriori algorithm and time series forecasting within a Business Intelligence (BI) framework to optimize supply chain operations in the retail industry. The Apriori algorithm was utilized to identify significant purchasing patterns, enabling strategic decisions such as product bundling and cross-selling. Concurrently, time series forecasting, with an ARIMA model achieving a mean absolute percentage error (MAPE) of 8%, provided accurate demand predictions, supporting improved inventory management and resource allocation. The integration of these methods into a BI dashboard facilitated real-time monitoring and data-driven decisionmaking, leading to enhanced operational efficiency and reduced costs. While challenges such as data quality, computational resource demands, and user adaptability were observed, this research underscores the transformative potential of analytics in retail supply chain management. Future advancements in machine learning and IoT integration are recommended to further enhance system performance. Overall, this study demonstrates a pathway for retailers to achieve operational excellence and superior customer satisfaction through data-driven strategies.

Abstract

Indonesia's renewable energy penetration (12.3% in 2022) lags significantly behind 2030 targets (19-23%), with Cilegon City facing 1,167 unelectrified households and rising waste generation. This study assessed renewable energy development potential through LEAP-based electricity demand modeling (2023-2033) and technical-economic evaluation of solar photovoltaic and Refuse-Derived Fuel (RDF) systems. Meteorological and waste generation data informed engineering calculations and financial feasibility analysis. LEAP projections indicate residential electricity demand reaching 728.1 MWh per household by 2033, driven by 13.9% population growth. Off-grid solar PV systems demonstrate viability with Rp. 5,774/kWh levelized cost for unserved households. The proposed UPTD 3 Merak RDF facility shows strong economics: 22 tonnes/day capacity, 2-year payback, Rp. 12.5 billion NPV, and 3.01 benefit-cost ratio. Findings reveal that institutional rather than technical barriers impede deployment, highlighting needs for standardized subsidies, clarified jurisdictional frameworks, and municipal-utility partnerships. This research advances urban renewable energy planning by integrating bottom-up energy modeling with localized assessments, providing replicable frameworks for Indonesian cities pursuing energy transition and environmental sustainability goals.

Abstract

This study aims to investigate the influence of overhang inclination angle and nozzle temperature on the surface roughness of the overhang section in a 3D printed object using Polylactic Acid (PLA) material with the Fused Deposition Modeling (FDM) method. An experimental approach was employed by varying the overhang angles (35˚, 45˚, and 55˚) and nozzle temperatures (210˚C, 220˚C, and 230˚C) during the printing process. Surface roughness measurements were performed on unsupported overhang areas using a surface roughness tester. The results showed that surface roughness increased with greater overhang angles and higher nozzle temperatures. The lowest surface roughness value was recorded at 210˚C with a 35˚ overhang angle, while the highest was observed at 230˚C with a 55˚ overhang angle. These findings indicate that controlling the nozzle temperature and overhang angle is crucial for achieving optimal surface quality in overhang printing. This study is expected to contribute to the optimization of FDM process parameters to produce smoother surfaces.
