Judul: Analysis of Tsunami's Vulnerability Level and Mitigation Study Case: Tasikmalaya Regency's Coast
Abstrak: Kondisi geografis dan geologis menjadikan Indonesia rawan terhadap bencana tsunami. Salah satu wilayah pesisir yang memiliki potensi terjadinya tsunami adalah Pesisir Kabupaten Tasikmalaya. Berdasarkan hal tersebut, diperlukan adanya analisis tingkat kerawanan dan upaya mitigasi tsunami dengan tujuan memperkirakan luas wilayah yang terdampak tsunami, menganalisis tingkat kerawanan tsunami, memperkirakan jumlah penduduk yang terdampak, memetakan shelter dan jalur evakuasi tsunami, serta merencanakan upaya mitigasi struktural tsunami. Metode yang digunakan, tool model builder, weighted overlay, InaSAFE, dan Network Analyst. Hasil pemodelan menunjukkan tsunami setinggi 10, 15, dan 20 meter dapat menggenangi wilayah seluas 12,25 km2, 18,47 km2, dan 24,69 km2. Wilayah Pesisir Kabupaten Tasikmalaya didominasi oleh tingkat kerawanan rendah sebesar (54,62%), kemudian tingkat kerawanan sangat rendah (26,25%), tingkat kerawanan sedang (12,61%), tingkat kerawanan tinggi (5,30%), dan tingkat kerawanan sangat tinggi (1,22%). Jumlah penduduk terdampak tsunami setinggi 10, 15, dan 20 meter adalah sebanyak 8.280, 12.320, dan 17.770 orang. Terdapat 59 jalur evakuasi, dimana jalur yang termasuk kategori sedang sebanyak 27 jalur, kategori dekat 14 jalur, kategori sangat dekat dan jauh masing-masing sebanyak 9 jalur. Upaya mitigasi struktural yang dilakukan adalah dengan membuat green belt dan sea wall yang efektif mereduksi tsunami dengan tinggi di bawah 15 meter., Geographical and geological conditions make Indonesia vulnerable to tsunami disasters. One of the coastal areas that has the potential for a tsunami is Tasikmalaya Regency’s Coast. It is necessary to analyze tsunami’s vulnerability and mitigation to describing the area affected by the tsunami, analyzing the level of tsunami vulnerability, estimating the number of people affected, mapping shelters and tsunami exit routes, and planning structural tsunami mitigation. Methods used, model builder, weighted overlay, InaSAFE, and Network Analyst. The results show that tsunami as high as 10, 15 and 20 meters can inundate areas of 12,25 km2, 18,47 km2 and 24,69 km2. Tasikmalaya Regency’s Coast is dominated by a low level of vulnerability (54,62%), then a very low level of vulnerability (26,25%), a medium level of vulnerability (12,61%), a high level of vulnerability (5,30%), and a very high level of vulnerability (1,22%). The number of people affected by tsunamis as high as 10, 15 and 20 meters was 8.280, 12.320 and 17.770 people. There are 59 exit routes, which there are 27 routes in the medium category, 14 routes in the near category, and 9 routes in the very near and far categories. The structural mitigation efforts carried out are by creating a green belt and sea wall which are effective in reducing tsunamis with a height of below 15 meters.

Judul: Pemetaan Shelter dan Jalur Evakuasi Tsunami Studi Kasus: Kabupaten Bantul.
Abstrak: Terdapat potensi tsunami setinggi 20 meter yang dapat terjadi di sepanjang pesisir selatan Pulau Jawa. Bantul merupakan salah satu daerah yang rentan akan bencana tsunami tersebut sehingga diperlukan upaya mitigasi dalam bentuk dan pembuatan jalur evakuasi serta lokasi yang tepat dijadikan tempat evakuasi (shelter). Metode yang digunakan dengan bantuan aplikasi Sistem Informasi Geografis antara lain pemodelan inundasi tsunami, weighted overlay, dan network analysist dengan bantuan tools InaSafe. Hasil pemodelan inundasi tsunami menunjukkan tsunami ketinggian 10 meter menggenangi area seluas 9,72 km2, ketinggian 15 meter menggenangi area seluas 15,69 km2, dan ketinggian 20 meter menggenangi area seluas 21,29 km2. Kecamatan Kretek, Sanden, dan Srandakan terdampak oleh hasil pemodelan tsunami tesebut.. Terdapat 8940 penduduk terdampak tsunami run up 10 meter, 15060 penduduk untuk run up tsunami 15 meter, dan 23870 penduduk untuk run up tsunami 20 meter sebesar 23870 penduduk. Hasil pemodelan menunjukkan 41 rute evakuasi tsunami dengan 16 jalur yang dikategorikan sangat jauh, 3 jalur dikategorikan jauh, 14 jalur yang dikategorikan sedang, dan 5 jalur yang dikategorikan dekat, dan 3 jalur yang dikategorikan sangat dekat., There is a potential for a tsunami as high as 20 meters that could occur along the southern coast of Java Island. Bantul is one of the areas that is vulnerable to the tsunami disaster, so mitigation efforts are needed in the form and creation of evacuation routes and appropriate locations for evacuation (shelter). The methods used with the help of the Geographic Information System application include tsunami inundation modeling, weighted overlay, and network analysis with the help of InaSafe tools. The results of the tsunami inundation model show that a tsunami with a height of 10 meters inundated an area of 9.72 km2, a height of 15 meters inundated an area of 15.69 km2, and a height of 20 meters inundated an area of 21.29 km2. Kretek, Sanden and Srandakan sub-districts were affected by the results of the tsunami modeling. There were 8940 people affected by the 10-meter tsunami run-up, 15060 people for the 15-meter tsunami run-up, and 23870 people for the 20-meter tsunami run-up of 23870 people. The modeling results show 41 tsunami evacuation routes with 16 lanes categorized as very far, 3 routes categorized as far, 14 routes categorized as medium, 5 routes categorized as close, and 3 routes categorized as very close.

Judul: Sintesis Flavonol melalui 2’-Hidroksikalkon
Abstrak: Flavonol is a class of flavonoids commonly found in fruits and vegetables. Flavonol is very useful, especially in food sector and health. In this study, flavonol unsubstituted was successfully synthesized from an intermediate material 2’-hydroxychalcone. The 2’-hydroxychalcone was synthesized by Claisen-Schmidt condensation method between o-hydroxyacetophenone and benzaldehyde using 4 different catalysts, namely KOH 60%, solid pellet of KOH-grinding technique, BF3-Et2O, and NaH in DMF. The KOH 60% was the best catalyst, giving the highest yield (57%). Afterward, the flavonol was synthesized in 1-stage oxidation cyclization of o-hydroxyacetophenone using Algar-Flynn-Oyamada (AFO) reaction, giving 76%. The flavonol total yield from 2’-hydroxychalcone was 43%. All synthesized products were characterized by their melting points and their spectra. The success of the synthesis flavonol opens the way to synthesis of useful flavonol derivatives such as quercetin and kaempferol.
