Abstract

Agregat merupakan komponen utama dari lapisan perkerasan jalan yaitu berkisar antara 90-95% berdasarkan prosentase beratnya. Daya dukung dan stabilitas lapisan permukaan jalan ditentukan dari sifat – sifat, bentuk butir, dan gradasi agregatnya. Namun untuk mendapatkan agregate yang memenuhi syarat sulit dilakukan jika agregat di ambil langsung dari alam (quarry). Sehingga perlu identifikasi awal batuan dengan menggunakan metode analisis petrografi sebelum dilakukan pengolahan di stone crusher.Dalam penelitian ini pengujian yang dilakukan adalah berat jenis, penyerapan air, abrasi, aggregate impact value, soundness test agregat, dan petrografi agregat yang kemudian dibuat campuran laston untuk mencari stabilitas marshall dengan variasi campuran aspal 4; 4,5; 5; 5,5; 6.Dari kajian petrografi agregat batuan dari quarry Ampel Boyolali merupakan jenis batuan basalt yang mempunyai kandungan mineral plagioklas (40%), piroksen (8%), hornblende (2%), Kalsium feldspar (5%), mineral opak (10%) dan massa dasar berupa gelas volkanik (35%). Sedangkan quarry Kramat Kramat merupakan jenis batuan andesit yang mempunyai kandungan mineral plagioklas (40%), piroksen (15%), mineral opak (3%) dan massa dasar berupa gelas volkanik (42%).  Menurut kandungan mineral penyusun batuan tersebut pada kadar aspal optimum pengujian Marshall Test jenis batuan basalt dari quarry Ampel Boyolali pada kadar aspal optimum memiliki stabilitas 996, 720 Kg, porositas 11,05 %, flow 3,61 mm, densitas 2,201 g/cm3, dengan Marshall Quotien 295,389 kg/mm. Sedangkan jenis Batuan andesit dari quarry Kramat  pada kadar aspal optimum memiliki stabilitas 898,852 Kg, porositas 10,5 %, flow 3,52 mm, densitas 2,224 g/cm3, dengan Marshall Quotien 298,943 kg/mm.

Abstract

The land registration system in Indonesia plays an important role in managing natural resources and protecting land rights, which has a direct impact on the performance of public services. This research explores the performance of land registration at the Gorontalo District Land Office, with a focus on efforts to systematically increase land registration. Even though there have been good achievements in the land redistribution program and the unsystematic issuance of certificates, registration results still show less than optimal performance. The main problems include complicated bureaucracy, lack of human resources, and wrong public perceptions regarding proof of land ownership. The research method uses a qualitative approach with interviews with 15 key informants and 5 people who have registered land. The research results show that increasing socialization, employee training and proactive communication are very necessary to improve public service performance. Apart from that, management of community expectations must be considered so that the registration process is more efficient. With these steps, it is hoped that public confidence in the land registration system can increase, and legal certainty over land rights is guaranteed, which ultimately supports better public service performance in Gorontalo Regency.
