Abstract

The use of disaster insurance for public infrastructure is still uncommon in Indonesia, including in Semarang. The success of the adoption of disaster insurance for public infrastructure is inevitably dependent on the acceptance of stakeholders. The aim of this study is to analyse the power and interest of stakeholders towards the use of disaster insurance for public infrastructure in Semarang. Data was collected via interviews and focussed group discussions with stakeholders of Semarang government officials, asset managers, users, etc. The power-interest grid of stakeholders divides the stakeholders based on their levels of power and interests, resulting in four categories, i.e. players, subjects, crowds, and context setters. This research identified the players are the Mayor, Regional Disaster Management Authority, and Regional Financial and Asset Management Authority (5.5%); the subjects category includes The Public Works Department of Human Settlements and Highways, Public Works Department, Trade Department, majority Public Health Center (40.7%); the crowds are Education Department and majority public schools (53.7%); and no context setters (0%). This study found that low trust in the insurer is a major factor causing a lack of interest in the use of insurance. The results of this study are valuable to understand the stakeholder map of Semarang city based on power and interest aspects, and serve as a basis for developing disaster insurance adoption strategies for public infrastructure.

Abstract

Penelitian ini bertujuan untuk menganalisis tingkat efisiensi serta kehilangan air pada jaringan daerah irigasi Bendung Pandi yang berlokasi di Desa Ngawen, Kecamatan Margorejo, Kabupaten Pati. Studi ini dilakukan di saluran irigasi primer, sekunder, maupun tersier. Analisis efisiensi dan kehilangan air dilakukan dengan metode perbandingan antara debit masuk dan debit keluar. Data primer yang digunakan adalah kecepatan aliran air, yang diukur menggunakan current meter pada saluran primer maupun sekunder, serta pelampung untuk saluran tersier. Selain itu, digunakan juga data sekunder dari Stasiun Klimatologi Jawa Tengah berupa catatan evaporasi selama 10 tahun terakhir. Hasil analisis menunjukkan bahwa total kehilangan air pada jaringan daerah irigasi Bendung Pandi mencapai 15,23%. Air yang hilang akibat evaporasi tergolong rendah, sehingga penyebab utama kehilangan air lebih berkaitan dengan kondisi fisik saluran. Kehilangan terbesar terjadi pada saluran irigasi sekunder-1, sekunder-4, dan saluran tersier yang berbasis tanah. Secara keseluruhan, rata-rata efisiensi dari jaringan daerah irigasi Bendung Pandi mencapai 84,76%, dengan rincian efisiensi pada saluran primer 93,35%, saluran sekunder 83,01%, dan saluran tersier 77,93%.

Abstract

Cracks caused by excessive loads that exceed compressive strength remain a major issue when applying paving blocks. This study aims to develop environmentally friendly paving blocks by utilizing PET plastic waste and cattle bone powder as substitute materials, and to evaluate their effect on the compressive strength characteristics of paving blocks. Cattle bone powder was used as a partial cement substitute in proportions of 0%, 15%, 20%, and 25%, while PET plastic waste was used as a partial sand substitute at 0%, 5%, 10%, and 15%, intended to fill micro-voids in the concrete mixture. The paving block samples were rectangular, measuring 20 × 10.5 × 6 cm. Based on compressive strength test results at 7 days, converted to 28 days, the highest strength value was achieved with the mixture containing 15% cattle bone powder and 5% PET, reaching 29.22 MPa—meeting the SNI 03-0691-1996 quality standard for Class B. The lowest compressive strength was recorded in the mixture with 20% cattle bone powder and 15% PET plastic, at 6.89 MPa. The lowest water absorption value was found in the mix with 0% cattle bone powder and 5% PET, at 2.79%, while the highest water absorption occurred in the mixture with 25% cattle bone powder and 15% PET, at 8.06%.
