Judul: Risk Analysis and Mitigation Strategy for a Tsunami on the South Coast of Java Case Study: Cilacap District
Abstrak: Indonesia memiliki banyak daerah rawan bencana tsunami. Faktor yang dapat menyebabkan terjadinya tsunami salah satunya gempa bumi yang tidak dapat dihindari mengingat posisi tata letak geografis Indonesia yang berada di Zona megathrust. Penelitian dilakukan di salah satu kabupaten yang berada di selatan Pulau Jawa yaitu Kabupaten Cilacap. Pemodelan tsunami dilakukan menggunakan Model Crunch untuk memprediksi tingkat risiko bencana tsunami. Metode ini merupakan hasil perkalian antara bahaya (hazard) dengan kerentanan (vulnerability). Berdasarkan hasil Weighted Overlay Analysist, kerentanan wilayah pesisir Kabupaten Cilacap terhadap bencana tsunami yaitu berada pada kategori cukup rentan. Hasil Inundasi pada skenario tsunami ketinggian 10 m, 15 m, dan 20 m menunjukan bahwa hampir sebagian besar kecamatan di pesisir pantai Kabupaten Cilacap terdampak tsunami. Salah satu kecamatan dengan wilayah terdampak yang besar yaitu Kecamatan Kampung Laut dengan besaran berturut-turut 94.50 km2, 119.02 km2, dan 125.76 km2. Hasil identifikasi menunjukan bahwasannya perlu dilakukan pengembangan pada Kabupaten Cilacap, antara lain sarana peringatan dini yang perlu diperbanyak jumlahnya, pembangunan bangunan pemecah ombak didukung dengan penanaman bibit mangrove, penambahan jalur evakuasi, pembangunan bangunan shelter dengan struktur tahan gempa dan tsunami, penambahan pos lembaga penanggulangan bencana., Indonesia has many tsunami-prone areas. Factors that can cause a tsunami, one of which is an earthquake, which cannot be avoided considering Indonesia's geographic position in the megathrust zone. The research was conducted in one of the districts in the south of Java Island, namely Cilacap Regency. Tsunami modeling is carried out using the Crunch Model to predict the risk level of a tsunami disaster. This method is the result of multiplying the hazard and vulnerability. Based on the results of the Weighted Overlay Analysist, the vulnerability of the coastal area of Cilacap Regency to the tsunami disaster is in the moderately vulnerable category. Inundation results in the scenario of a tsunami with a height of 10 m, 15 m and 20 m show that almost most of the sub-districts on the coast of Cilacap Regency were affected by the tsunami. One of the sub-districts with a large affected area is Kampung Laut Sub-district with successive sizes of 94.50 km2, 119.02 km2 and 125.76 km2. The identification results show that it is necessary to develop Cilacap Regency, including increasing the number of early warning facilities, building breakwaters supported by planting mangrove seedlings, adding evacuation routes, building shelters with earthquake and tsunami resistant structures, adding disaster management agency posts.

Judul: Mapping the Level of Coastal Vulnerability to Tsunami Disaster on the South Coast of Cilacap Regency, Central Java
Abstrak: Wilayah pantai selatan Kabupaten Cilacap termasuk salah satu wilayah yang mempunyai probabilitas yang tinggi dipengaruhi bencana gempa bumi dan tsunami. Hal ini disebabkan posisi wilayah Kabupaten Cilacap yang sangat dekat dengan pertemuan Lempeng Indo-Australia dan Lempeng Eurasia. Penelitian ini bertujuan untuk mengidentifikasi, memetakan dan menganalisis penyebaran tingkat kerentanan tsunami di wilayah pantai selatan Kabupaten Cilacap, Jawa Tengah. Peta kerentanan tsunami dibuat menggunakan Sistem Informasi Geografis (SIG) dengan metode tumpang susun (overlay) dengan lima parameter, yaitu elevasi daratan, kemiringan lahan, jarak dari garis pantai, jarak dari sungai, dan penggunaan lahan. Penelitian dibagi menjadi dua tahap yaitu tahap pengumpulan serta pengolahan data dan tahap survei lapang yang dilakukan di 4 kecamatan yaitu Kecamatan Cilacap Selatan, Kecamatan Cilacap Utara, Kecamatan Kesugihan dan Kecamatan Adipala. Klasifikasi tingkat kerentanan tsunami dibagi menjadi lima kelas yaitu sangat rendah dengan luas wilayah sebesar 268 ha (0,25%), rendah dengan luas wilayah sebesar 18.708,94 ha (17,16%), sedang dengan luas wilayah sebesar 54.510,29 ha (50%), tinggi dengan memiliki luas wilayah sebesar 33.711,67 ha (30,92%) dan sangat tinggi dengan luas wilayah sebesar 1.815,90 ha (1,67%)., The southern coastal area of Cilacap Regency is one of the areas that has a high probability of being affected by earthquakes and tsunamis. This is due to the position of the Cilacap Regency area which is very close to the meeting of the IndoAustralian Plate and the Eurasian Plate. This study aims to identify, map and analyze the distribution of tsunami vulnerability levels in the southern coastal area of Cilacap Regency, Central Java. The tsunami vulnerability map was created using the Geographic Information System (GIS) with the overlay method using five parameters, namely land elevation, land slope, distance from the coastline, distance from the river, and land use. The research was divided into two stages, namely the data collection and processing stage and the field survey stage carried out in 4 subdistricts, including the Sub-District of South Cilacap, North Cilacap, and Adipala. The classification of tsunami vulnerability level is divided into five classes: very low with an area of 268 ha (0,25%), low with an area of 18.708,94 ha (17,16%), medium with an area of 54.510,29 ha (50%), high with an area of 33.711,67 ha (30,92%) and very high with an area of 1.815,90 ha (1,67%).

Judul: Quality of Eggs Based on Different Age of Chickens from Yong's Farm, Seremban, Malaysia
Abstrak: This study aimed to determine the quality of eggs from different ages of chickens from Yong’s Farm, Seremban, Malaysia. The method used was 60 eggs were collected from three of different ages of chicken; 25 (n=20 eggs), 35 (n=20 eggs) and 58 weeks old (n=20 eggs). The variables included egg weight, shell thickness, yolk color, yolk index, albumen index and Haugh unit. The results showed the highest egg weight was recorded with 58 weeks old chicken. The egg shell thickness found at week 25 week (0,455 ± 0,08 mm), 35 weeks (0,495 ± 0,08 mm) and 58 weeks (0,475 ± 0,08 mm). Yolk color was at the highest mean of.12,6 ± 0,68 (25 weeks) while on week 35 and 58 it ranges between 5,45 ± 0,51 and 5,55 ± 0,51. The yolk index was recorded on week 25 and no specific trends were observed and the yolk index was not significant between 35 and 58 weeks of age. Albumen index was highest at week 25 were (0,129 ± 0,0), week 35 (0,113 ± 0,03) and week 58 (0,088 ± 0,02). The highest HU was recorded at week 25 (94,81 ± 5,33) and decreased to (90,52 ± 6,64) at week 35 and (81,95 ± 6,24) at week 58. It can be concluded that chicken influences both exterior and interior quality, except the yolk color with the quality of eggs decreasing as the age increases.
