Abstract

Pipa High Density Polyethylene (HDPE) telah menjadi pilihan utama dalam sistem perpipaan modern karena keunggulannya dalam fleksibilitas, ketahanan korosi, dan umur panjang. Makalah ini membahas pertimbangan teknis dan praktis dalam pemilihan pipa HDPE untuk dua aplikasi utama: sistem sumur bor dan saluran irigasi. Fokus utama diarahkan pada karakteristik pipa, kebutuhan tekanan dan aliran, kemudahan instalasi di lapangan, serta aspek biaya dan perawatan jangka panjang. Hasil kajian menunjukkan bahwa pipa HDPE menawarkan solusi yang efisien, tahan lama, dan ramah lingkungan, sangat cocok untuk digunakan dalam sistem distribusi air tanah dan jaringan irigasi pertanian. Rekomendasi diberikan terkait spesifikasi pipa berdasarkan tekanan kerja, diameter nominal, dan standar mutu yang harus dipenuhi untuk memastikan performa optimal di lapangan.

Abstract

The effect of institutional ownership on firm value with the conditional process model (CPM) approach: This study aims to test and analyze how and when Institutional Ownership is effective in increasing Firm Value. The research method uses a quantitative approach, the research design uses a descriptive approach, and an explanatory survey to test and analyze causal relationships. Research on public companies in Indonesia in the consumer-non-cyclical sector, as much as 488 pooled times series data with the analysis period 2016-2023, with the Conditional Process Model (CPM) approach to explain how (Mediation effect) and when / under what conditions (moderation effect) the effect occurs on the institutional ownership structure on firm value both directly and indirectly, to estimate the research model using Macro for SPSS V3.4. Research findings: institutional ownership, investment efficiency, and an independent board of commissioners affect increasing the value of the firm, The researcher produced a model formula that institutional ownership of the firm value through investment efficiency, is more visible to the company by involving an independent Board of Commissioners that leads to a high level, and investment efficiency can be used as a mitigation in making investment policies that can produce positive returns,  increase the value of the company, so that it can compete sustainably.
