Menggunakan data panel dinamis dari 68 perusahaan manufaktur yang tercatat di Bursa Efek Indonesia selama periode 2014-2018, penelitian ini menguji pengaruh moderasi ketidakpastian pada hubungan antara leverage dan investasi perusahaan. Ketidakpastian spesifik perusahaan, ketidakpastian pasar, ketidakpastian pasar keuangan dan ketidakpastian ekonomi dan politik digunakan sebagai proksi ketidakpastian. Penelitian ini menggunakan two step robust system Generalized Method of Moments (GMM). Hasil penelitian menunjukkan bahwa ketidakpastian dan interaksinya dengan leverage memiliki efek yang bervariasi pada investasi perusahaan. Studi ini menemukan bahwa hanya ketidakpastian pasar dan ketidakpastian ekonomi dan politik yang berpengaruh signifikan terhadap investasi perusahaan. Untuk efek moderasi, penelitian ini menemukan bukti bahwa interaksi antara ketidakpastian pasar dengan leverage melemahkan efek positif dari leverage pada investasi. Namun interaksi antara ketidakpastian ekonomi dan politik dengan leverage melemahkan efek negatif dari leverage pada investasi. ......

Model kecepatan lapisan bawah permukaan yang diestimasi pada proses pengolahan data seismik yang masih memiliki ketidakpastian posisi sebenarnya dari reflektor seismik atau kedalaman lapisan geologi. Penelitian ini melakukan analisis ketidakpastian dari kedalaman posisi lapisan reservoar pada Lapangan X. Hasil penelitian digunakan untuk membantu pemprediksi area target pengeboran sumur penilaian sebelum dilakukan pengembangan pada Lapangan X. Analisis dilakukan dengan menggabungkan dua metode yaitu analisis statistika dari proses koreksi peta kedalaman reservoar dan proses kalibrasi model kecepatan data seismik. Dari kedua analisis ini diketahui nilai maksimum ketidakpastian kedalaman pada batas atas reservoar sebesar 125ft. Distribusi nilai ketidakpastian kedalaman dilakukan dengan menggunakan acuan dari bentuk geologi lipatan Lapangan X untuk menghasilkan peta ketidakpastian kedalaman. Peta ketidakpastian kedalaman digunakan untuk mendapatkan peta lapisan reservoar dengan kasus dangkal, dasar dan dalam. Dari ketiga peta tersebut dikombinasikan dengan data sekunder kontak gas dan air (Gas Water Contact) dan asumsi akuisisi data pada sumur penilaian sehingga diperoleh prediksi area target pengeboran sumur penilaian dengan jarak terdekat 400 m dari sumur eksplorasi pada Lapangan X.

Penelitian ini menginvestigasi mengenai mekanisme spasial arsitektur yang hadir tanpa penerapan order. Dalam sejarahnya, proses perancangan arsitektur tidak pernah terlepas dari pengaplikasian rigid order sebagai paradigma ideal, meskipun didalam penerapannya order rigid cenderung menyebabkan beberapa permasalahan di kemudian hari. Penelitian ini menggunakan pendekatan contingency dan indeterminacy dengan potensinya dalam meredefinisi penerapan order rigid didalam perancangan arsitektur. Dalam pembahasan menemukan tiga aspek untuk menangani contingency, yaitu subjek yang selalu berubah, perubahan itu sendiri, dan kronologi waktu. Ketiga aspek ini untuk selanjutnya diguanakan untuk membedah beberapa studi kasus yang menggunakan pendekatan contingency dalam proes perancangannya. Hasil yang didapatkan pada penelitian ini adalah mekanisme spasial gradation spacr, dimana dengan mekanisme gradation space akan menghadirkan arsitektur yang dapat terlepas dari penerapan rigid order. Mekanisme spasial gradation space ini terbentuk dengan menyadari dan menghubungkan kemungkinan atas aspek perubahan intensitas yang secara alami terjadi pada alam, perubahan bentuk atau ukuran atas subjek, dan perubahan sensasi ruang. Untuk selanjutnya, dengan menggunakan mekanisme spasial gradation space didalam perancnagan, dapat meredefinisi bentuk arsitektur seperti boundary, spatial organization dan path yang dapat hadir tanpa penerapan order yang rigid. ......This paper investigates the spatial mechanism of architecture without order. During the history, architectural design process has never been separated from the application of rigid order as an ideal paradigm, although the application of rigid order tends to cause several problems in the future. The study utilized a contingency and indeterminacy approach with its potential to redefine the application of rigid order in architectural design. The discussion circulates the idea that contingency is emphasized in three things, i.e., subjects that keep changing, changes of subject, and chronological lines of time. These three aspects are further utilised to analyze precedents that used contingency approach through their design process and contingency on natural phenomenon. This paper proposes gradation space as a potential mechanism for developed architectural design by no rigid order. Mechanism system of gradation space can be formed by shifting intensity of natural force such as temperature and humidity, differential of size and volume of subject’s changes and immersive sensation and experience with the nature of constantly changing according to the possibilities. Further discussion by using this gradation zone within design process, can redefine architectural form such as boundary, spatial organization and path that can exist without rigid order.
