Judul: Deliniasi Wilayah Pioritas Penangan Rawan Kekeringan Di Lahan Pertanian (Studi Kasus: Sulawesi Selatan)
Abstrak: Drought in the agricultural land might be happened because of the late wet season, it’s cause inappropriate cropping pattern. Delineation of vulnerability drought areas must be done to anticipate crop failure areas. Drought vulnerability areas analize by three different aspects: climatological, hydrological and agronomical. Each aspects has role in the water availability for agriculture land. Approachment of climatological aspect, drought vulnerability areas showed by the sensitivity level of rainfall towards sea surface temperature (SST) anomalies in the Nino-3.4 region. The rainfall is divided in three period: wet season (MH) at November-February, first dry season (MK-1) at March-June and second dry season (MK-2) at July-October. The correlation between rainfall anpmalies and SST anomalies specify three different areas: high sensitive areas, low sensitive areas and non-significant areas. Significant areas is the regions where rainfall has correlation toward sea surface temperature anomaly where the regression produce P-value ≤ 0.05. Approachment of hydrological aspect, drought vulnerability areas determined by the density of stream pattern. In agronomy aspect, drought areas is determined from the type of agricultural land use. The integration of these three aspects result distribution of drought level areas in agriculture field, specifically rice-field. Results of the climatological aspect analysis shows that the drought areas more often in the west and south Sulawesi Selatan. While on the agronomy aspect, drought areas are dominated by rainfed lands and moor lands that spreads all over province.

Judul: Penentuan indeks kekeringan agro-hidrologi untuk analisis risiko kekeringan dan mitigasinya (Studi Kasus DAS Kariango Sulawesi Selatan).
Abstrak: Agro-Hydrological drought can be interpreted as a shortage of surface water and groundwater supplying and insufficient for the plants and society needs a certain period. So far there have been no study assessing the agro-hidrology drought index. This study develops a Drought Hazard Index (DHI) as an indicator of Agro-Hydrological drought. The model developed from a combination of dry season rainfall, ground water depth, distance of water sources, soil texture and Water Supply Vegetation Index (WSVI) using remote sensing and GIS methods. Further analysis was caeried out to develop vulnerability and risk of drought which gave an overview of areas that need to be formulated for drought mitigation in the Kariango watershed. Agro-hidrologi Drought Hazard Index was DHI = (0.33CH) + (0.27KAT) + (0.20SA) + (0.13T) + (0.06WSVI) with model validation results showed high similarity drought in the field. The results of the analysis of vulnerability describes 25 % of villages are classified vulnerable. In the drought risk analysis shows the highest class are 19.52 % and 40.98 % are the dominant from paddy fields So that the mitigation efforts created are made together in the form of regulation and capacity building with reference to the combination of risk parameters included hazard risk and vulnerability.

Judul: Desain Gerbang Logika Kuantum Fredkin Multi- Kontrol Berbasis Gerbang Toffoli Melalui Superposisi Gerbang Elementer
Abstrak: Gerbang Fredkin dapat dimanfaatkan sebagai sel pembangun rangkaian fulladder untuk proses komputasi. Karena sifatnya yang reversibel, gerbang tersebut dapat dibuat dari sususan gerbang-gerbang elementer dengan basis gerbang Toffoli. Pada penelitian ini, penulis mencari desain dari gerbang Fredkin multi-kontrol berbasis gerbang Toffoli dengan mengkombinasikan tiga jenis gerbang elementer, yaitu CNOT, CV, dan CV†. Penelitian ini juga memperhitungkan jumlah gerbang elementer yang digunakan (quantum cost) dan jalur tambahan (ancillae input) dari desain-desain gerbang Fredkin yang dihasilkan. Dari hasil penelitian ditunjukkan bahwa gerbang Fredkin multi-kontrol dapat dibentuk oleh susunan tiga gerbang Toffoli multi-kontrol. Kemudian, gerbang-gerbang tersebut dapat direkonstruksi menjadi susunan gerbang-gerbang elementernya. Jumlah quantum cost dan ancillae input akan semakin besar seiring bertambahnya jumlah kontrol yang digunakan.
