Judul: Evaluasi Potensi Bahaya Banjir di DKI Jakarta  Menggunakan  Analisis  Multi-Kriteria  dan  Satelit  Berbasis  Flood  Hazard Index (FHI)
Abstrak: Floods are one of the most destructive and common natural disasters in the world. Globally, flood disasters have an increasing trend from year to year. In Indonesia istelf, the number of flood disasters from 2011 to 2020 was recorded at 7.574 cases which caused losses in several aspects of life. Losses caused by flooding include death, minor/severe injuries, missing persons, damage to houses, access roads, as well as education and health centers. Various methods have been applied as a preventive action for flood control. One of the methods commonly used to prevent flooding is creating water infiltration channels and cleaning rivers periodically from garbage. However, there is another approach that can be used, namely by making a flood hazard map based on the Flood Hazard Index (FHI). The FHI method is able to combine Geographic Information System (GIS) analysis with Multi Criteria Decision Analysis (MCDA) to obtain flood hazard maps. The MCDA technique used is Analytical Hierarchy Process (AHP) to determine the weight of the influence of factors on flood events. This study aims to obtain the level of flood hazard in DKI Jakarta and the most influential factors in causing flooding. In the analysis process, the seven factors that cause flooding in DKI Jakarta are defined, namely flow accumulation, distance from rivers, density of river networks, slopes, rainfall intensity, land cover, and geology. AHP analysis is used to obtain weighted scores, while GIS analysis is used to obtain scores. The value of weights and scores are combined to obtain FHI. Sensitivity analysis was then carried out to obtain the effective weights used in constructing the flood hazard index. The FHI map, FHI sensitivity (FHIS), and FHI equal weight (FHIW) were validated using the 2013 flood inundation map to find the index that best represents flood events in DKI Jakarta. The results of the analysis show that the FHIS index is best used to represent the flood hazard in DKI Jakarta (59%). Factors that influence in causing flooding are rainfall intensity, followed by land use, and slope. FHIS values have a pattern of high in the north and low in the south. This indicates that the northern region has a higher level of danger than the southern region. This phenomenon occurs due to the high intensity of rain in the northern part of Jakarta due to its location close to the Java Sea. In addition, the northern area of Jakarta is downstream of 13 rivers so it has a higher potential for flooding.

Judul: Evaluation of Flood Hazard Index (FHI) Parameter Weight In Mapping Flood Hazard Areas In Citarum Hulu Watershed
Abstrak: Bencana hidrometeorologi terutama banjir merupakan bencana yang sering terjadi di Indonesia. Banjir akan semakin parah apabila telah memasuki wilayah pemukiman penduduk. DAS Citarum Hulu merupakan salah satu daerah aliran sungai prioritas di Indonesia yang memerlukan upaya mitigasi terhadap sebuah bencana banjir. Penelitian ini bertujuan menganalisis dan memetakan daerah bahaya banjir di DAS Citarum Hulu menggunakan pendekatan Flood Hazard Index (FHI). FHI dihitung berdasarkan tujuh parameter yaitu topografi, kelerengan, akumulasi aliran permukaan, intensitas hujan, jarak dari sungai, geologi, dan tutupan lahan yang diberikan bobot menggunakan pendekatan bobot sama dan Analytical Hierarchy Process (AHP). Hasil analisis menunjukkan bahwa bobot parameter FHI dengan pendekatan AHP tertinggi adalah intensitas hujan sebesar 1,911 dan bobot terendah adalah topografi sebesar 0,294. Berdasarkan perhitungan menggunakan metode FHI, maka DAS Citarum Hulu didominasi oleh tingkat bahaya banjir sedang. Nilai akurasi FHI menggunakan pendekatan bobot sama sebesar 85,8% dan pendekatan AHP sebesar 87,3%. Hasil ini memberikan gambaran tingkat bahaya banjir yang dapat digunakan oleh pengampu dan pengambil kebijakan dalam perencanaan sumberdaya air wilayah.

Judul: Korpus Luteum Persisten pada Sapi serta Beberapa Aspek Penanggulangannya
Abstrak: Korpus luteum pada ovarium terbentuk pada hari ke lima atau ke enam setelah ovulasi terjadi. Bila pada uteru tidak terjadi kebuntingan, korpus luteun dinonaktifkan oleh hormon luteolitik yaitu prostaglandin yang dihasilkan dinding uterus. Jika pada uterus terjadi kebuntingan, korpus luteum tetap bertahan pada ovarium dan berfungsi secara normal, disebut korpus luteum graviditatum. Korpus luteum graviditatum aktif pada sapi betina (erti) selama total waktu 320 hari dalan satu tahun.
