Floating Raft

Penelitian ini bertujuan untuk mengetahui respon pertumbuhan dan produksi tiga varietas selada dengan teknik hidroponik menggunakan sistem Floating Raft ditinjau dari tinggi tanaman, jumlah daun dan berat basah di dekat input, tengah dan dekat output. Waktu penelitian yaitu 19 Mei – 13 Juni 2018 di PT. Hidroponik Agrofarm Bandungan. Pengambilan sampel dilakukan dengan cara simple random sampling pada ketiga varietas selada yaitu selada Jonction varietas L. sativa capitata, selada Romaine varietas L. sativa longifolia dan selada Red Saladbowl varietas L. sativa crispa. Penelitian menggunakan Rancangan Acak Lengkap dengan 3 kali ulangan. Data dianalisis menggunakan uji sidik ragam (ANOVA) dan dilanjut menggunakan uji BNT 5%. Hasil penelitian menunjukkan bahwa respon pertumbuhan dan produksi tertinggi dari tiga varietas selada pada hidroponik sistem Floating Raft terjadi pada selada yang ditempatkan di dekat input nutrisi.

This paper explores the possibility and plausibility of developing a hybrid simulation method combining agent-based (AB) and system dynamics (SD) modeling to address the case study of produced water management (PWM). In southeastern New Mexico, the oil and gas industry generates large volumes of produced water, while at the same time, freshwater resources are scarce. Single-method models are unable to capture the dynamic impacts of PWM on the water budget at both the local and regional levels, hence the need for a more complex hybrid approach. We used the literature, information characterizing produced water in New Mexico, and our preliminary interviews with subject matter experts to develop this framework. We then conducted a systematic literature review to summarize state-of-the-art of hybrid modeling methodologies and techniques. Our research revealed that there is a small but growing volume of hybrid modeling research that could provide some foundational support for modelers interested in hybrid modeling approaches for complex natural resource management issues. We categorized these efforts into four classes based on their approaches to hybrid modeling. It appears that, among these classes, PWM requires the most sophisticated approach, indicating that PWM modelers will need to face serious challenges and break new ground in this realm.
