Abstract

Electricity is an essential need in almost all human activities, making it a vital component of everyday life. However, in the process of distributing it to customers, there is often a difference between the energy delivered and the energy sold, known as energy loss or shrinkage. This shrinkage can be categorized into two types, namely technical and non-technical shrinkage. PT PLN (Persero) uses the Jogja formula to map and analyze these two types of shrinkage, allowing a percentage comparison between technical and non-technical shrinkage. The focus of this research is on efforts to overcome non-technical shrinkage, especially in Muara Tebo ULP. PT PLN (Persero) implements preventive measures, including public education on the efficient and safe use of electrical energy, as well as the routine implementation of the Electricity Usage Control (P2TL). The purpose of these measures is to reduce non-technical losses that occur in the use of electricity. The results of the P2TL implementation in ULP Muara Tebo showed an increase in average kWh generation from 193,193 kWh in the January to May period to 216,582 kWh in June. This increase contributed significantly to the reduction of total shrinkage by 2.51% in June. This research confirms that a structured enforcement and education strategy can effectively improve energy distribution efficiency and reduce non-technical losses, supporting the overall operations of PT PLN (Persero).Keywords: energy loss, non-technical loss, formula jogja, P2TL

Abstract

The construction of government office buildings requires technical planning documents that comply with national standards. This study aims to evaluate the technical planning documents for the rehabilitation of the South Sumatra Settlement Infrastructure Agency (BPPW) Office Building, focusing on structural and material aspects based on Checklist SE DJCK 04 of 2022. A descriptive qualitative method was applied through document analysis and technical discussions. The evaluation covers legal compliance, building description, document completeness, normative references, material specifications, structural system, load analysis, structural calculation, and construction detailing. Results indicate that the planning documents generally meet technical standards, though some discrepancies were found, such as incomplete geological maps, absence of wind load analysis, and inconsistencies in material specifications across documents. In conclusion, the documents are deemed suitable as a project implementation guide, with recommended improvements in cartography, lateral load analysis, and cross-document harmonization. Suggestions are provided to enhance the integrity of technical documentation through normative updates and cross-validation to ensure optimal safety and construction quality.Keywords: Technical Evaluation, Building Structure, Material Specification, Checklist, Building Rehabilitation

Abstract

The widespread use of concrete in the construction industry contributes significantly to environmental degradation, primarily through CO₂ emissions from cement production and natural resource depletion for aggregate sourcing. This study investigates the feasibility of using seashell waste as a partial replacement for fine aggregate in concrete, aiming to maintain structural performance while promoting sustainability. A control concrete mix and an innovative mix incorporating seashell waste were prepared, with compressive strength tests conducted at 28 days. The results show that the seashell concrete achieved a compressive strength of 35.09 MPa, slightly surpassing the control concrete's 35 MPa. This minor increase is attributed to the calcium carbonate content of seashells, which contributes to a stable cementitious matrix similar to that of limestone.The findings suggest that seashell waste, abundant in coastal regions, can be effectively utilized as an eco-friendly alternative in concrete production without compromising structural integrity. By partially substituting fine aggregates with seashells, this study highlights a potential solution for reducing reliance on natural sand while supporting marine waste management. This research provides a basis for future studies on optimizing seashell content in concrete and exploring its durability under varying environmental conditions, contributing to sustainable construction practices.

Abstract

Jalan Moga - Guci merupakan akses penting menuju destinasi wisata di Kabupaten Tegal, namun karena kondisi geometrik jalan yang sulit dan minimnya sarana dan prasarana keselamatan, maka jalan tersebut menjadi rawan terjadinya kecelakaan. Tujuan dari penelitian ini untuk menemukan kemungkinan risiko berdasarkan penerapan konsep Self-Explaining Road (SER) dan Forgiving Road (FR), dengan metode Hazard Identification and Risk Assessment (HIRA). Pelaksanaan penelitian ini melalui observasi lapangan sepanjang 3,016 km dan menganalisis 12 titik defisiensi jalan. Hasil evaluasi menunjukkan bahwa 66% dari potensi bahaya berada dalam kategori risiko moderate, 17% high, dan 17% low. Mayoritas bahaya memiliki tingkat kemungkinan kejadian unlikely namun berdampak moderate hingga major jika terjadi kecelakaan. Temuan risiko tertinggi berada di titik STA 1+800 dan 2+400 akibat kombinasi kerusakan perkerasan dan visibilitas rendah. Studi ini membuktikan bahwa penerapan prinsip Self-Explaining Road (SER) dan Forgiving Road (FR) dalam desain jalan dapat membantu meminimalisir risiko kecelakaan. Diperlukan intervensi berbasis rekayasa lalu lintas untuk meningkatkan keselamatan di koridor pada jalur tersebut.
