Abstract

Clays are soft soil which have a low bearing capacity and potentially to failure. Utilization of additive material is an one way that can be applied to stabilize the clay. This study was conducted to determine the effectiveness of using POFA which is a local available material as an one alternative in stabilizing the clay by increasing its bearing capacity. The research focused on the influence of the POFA percentage with CBR value and the value of Cu in the clay stabilization. The results showed that the increasing of POFA percentage and curing process resulted in the increasing CBR and Cu values.  The average increase in the value of CBR curing method 1 to CBR without curing by 0,07% at the top and the bottom of the CBR. whereas for the curing method 2 by 2,29% at the top of CBR and 2,41% at the bottom of CBR. For cu values, the average increase by 1,10 kPa for curing method 1, and 14.65 kPa for curing method 2. It shows an increase in the value of the bearing capacity of the clay.  Key Words: CBR value, cu value, clay, POFA.

Abstract

The Indonesian domestic aviation industry continues to experience significant growth in line with increasing public mobility and expanding regional access. Citilink, a subsidiary of Garuda Indonesia operating as a low-cost carrier (LCC), strives to strengthen its national market share through the implementation of adaptive and innovative marketing strategies. This study aims to analyze Citilink's marketing strategy to win the Indonesian domestic aviation market competition in 2024. Using a qualitative approach and descriptive methods, data were collected through interviews with Citilink management, observations in various operational areas, and secondary document reviews. The results show that Citilink consistently applies the marketing mix (7Ps) covering product, price, place, promotion, people, process, and physical evidence. Competitive pricing strategies, aggressive digital promotional campaigns, and collaboration with various industrial sectors and local governments are key to expanding market reach. Citilink positions itself as a "Smart Value Airline" that prioritizes a combination of affordable prices and quality service. Challenges faced include limited infrastructure, intense price competition, and public perception of LCC airline services. This study concludes that Citilink's marketing strategy is generally relevant to the characteristics of the Indonesian market and capable of enhancing its national competitiveness. These findings are expected to serve as a strategic reference for industry players and contribute to academics' development of aviation marketing studies.

Abstract

Keandalan data aeronautika merupakan faktor penting dalam mendukung keselamatan dan efisiensi operasi penerbangan. Pusat Informasi Aeronautika (PIA) memiliki tanggung jawab dalam memastikan bahwa data yang dipublikasikan akurat, mutakhir dan sesuai standar ICAO Annex 15 serta PANS-AIM. Namun, hasil publikasi Pusat Informasi Aeronautika masih menunjukkan adanya ketidakakuratan data, seperti perbedaan koordinat, duplikasi waypoint, serta inkonsistensi prosedur yang berpotensi menimbulkan kebingungan pengguna, meningkatkan risiko human error, dan menurunkan tingkat keselamatan penerbangan. Penelitian ini bertujuan untuk menganalisis efektivitas penerapan Sistem Manajemen Mutu (SMM) terhadap peningkatan kualitas data aeronautika. Metode penelitian menggunakan pendekatan pengukuran efektivitas melalui survei terhadap personel Aeronautical Information Management (AIM) serta pengumpulan data-data yang berasal dari peraturan, dokumen, buku, laporan, catatan dan rekaman serta foto. Hasil penelitian menunjukkan bahwa penerapan SMM berpengaruh signifikan terhadap kualitas data aeronautika. Kesimpulan penelitian menegaskan bahwa SMM memiliki kontribusi terhadap kualitas publikasi data aeronautika. Temuan ini dapat menjadi dasar perbaikan berkelanjutan dalam manajemen data aeronautika di Pusat Informasi Aeronautika.
