Abstract

This article discusses the use of the Black Scholes model to calculate insurance premium prices based on the rainfall index. The Black Scholes model is one of the models used to determine option prices. The research method used is to study the material through mathematics journals and collect data. The data used in this study are rainfall data and rice production data in North Sulawesi from 2018 to 2020. Based on the results and discussion, the quarterly rainfall data that has a strong correlation is the third quarter rainfall. At the 5th percentile, the third quarter rainfall data is 450.22 mm. For the latest rainfall data size (450.22 mm) the premium obtained is IDR 231,912.09. From the calculation results, the higher the value for both sizes, the greater.

Abstract

Penelitian ini bertujuan untuk mengevaluasi stabilitas tebing sungai dalam rangka proyek pembangunan sarana dan prasarana pengendalian banjir Batang Lembang (Tahap II) yang berlokasi di Solok, Sumatera Barat. Proyek ini mencakup tiga lokasi utama, yaitu Selayo di Kabupaten Solok (BH01), VI Suku di Kota Solok (BH02), dan KTK di Kota Solok (BH03). Analisis stabilitas lereng dilakukan menggunakan metode slope/w dan faktor keamanan yang mengacu pada SNI 8640-2017 mengenai "Persyaratan Perancangan Geoteknik". Berdasarkan hasil analisis, faktor keamanan pada beberapa kondisi di lokasi Selayo dan VI Suku tidak memenuhi standar minimum yang ditetapkan, sementara di lokasi KTK, faktor keamanan menunjukkan hasil yang sesuai dengan persyaratan. Penelitian ini juga mengusulkan modifikasi terhadap geometri lereng dan penambahan elemen perkuatan, seperti cerucuk dolken, untuk meningkatkan stabilitas tebing di lokasi yang tidak memenuhi syarat. Selain itu, evaluasi dilakukan terhadap potensi modifikasi penampang sungai untuk memperbaiki kestabilan lereng, dengan fokus pada perubahan geometri dan penambahan elemen perkuatan. Hasil analisis menunjukkan bahwa dengan penerapan modifikasi tersebut, beberapa lokasi yang sebelumnya tidak memenuhi standar faktor keamanan dapat diperbaiki, sehingga sesuai dengan ketentuan geoteknik yang berlaku. Temuan dari penelitian ini memberikan rekomendasi teknis untuk meningkatkan stabilitas tebing sungai, yang diharapkan dapat memberikan kontribusi penting terhadap kelancaran pembangunan sarana dan prasarana pengendalian banjir yang aman dan berkelanjutan di kawasan Batang Lembang. Penelitian ini juga menawarkan wawasan mengenai penerapan standar geoteknik terbaru dan menekankan pentingnya analisis kondisi lokal dalam merancang solusi mitigasi bencana banjir yang efektif. Selain itu, hasil penelitian ini dapat menjadi acuan bagi perencanaan pembangunan serupa di wilayah lain dengan karakteristik yang serupa.

Abstract

Drought is the decrease in the amount of rainfall from its normal condition and depends on how long it lasts. This study aims to determine the characteristics of drought that occurs in the longest duration of drought and the largest number of drought in the location of rain stations spread in Palambayan basin. Then can be used as early warning of drought disaster and help for the interest of planning design at Palambayan watershed. The method used to analyze drought is Run Theory method. The location of the study was in the Palambayan Basin of West Sumatra Province. The data used are monthly rainfall for 10 years (2007-2016) from 2 rain stations located in the Palambayan River Basin and 1 Rain Station located outside the Palambayan River Basin. The results showed that the largest cumulative drought occurred in 2008 of 283.49 mm at Muaro Tantang rain station. For the longest duration of drought is 9 months in 2009. Based on the result of drought distribution map using Geographic Informaton System (GIS), the worst drought station is Gumarang Station.Keywords: Drought Analysis, Run Theory, Drought Index
