Judul: Kualitas Telur Tetas dan Perkembangan Somite (Tulang Belakang) pada Embrio Ayam Arab dari Umur Induk yang Berbeda
Abstrak: Arab chicken is one of the most favorite local layer chicken developed in Indonesia due to their high productivities. The egg qualities are highly influenced by the hen age. Somitogenesis is an early step in chick embryo development. The data of somite development on chick embryo is very limited, especially in Arab chicken. Therefore this research aimed to analyze the influence of hen breeder age on formation of somites. There were 99 eggs from 36, 42, and 54 weeks of hen age will be used in this study. The embryo samples were harvested in 24, 33, and 48 hours after incubation. The Complete Randomized Design was used to analyze exterior and interior of egg qualities such as the egg weight, egg shape index, shell weight and shell thickness. The number of somites will be analyzed descriptively. The results show that hen age had effect significantly the egg weight and the shell thickness (P<0,05). Hen age did not affect the egg shape index and the shell weight (P>0,05). There were died embryos from hen age of 54 weeks (22%) and 42 weeks (15,38%). The embryo from 42 week of hen age developed slower (15,38%) than embryo from 36 and 54 weeks.

Judul: Produksi dan Kualitas Telur Ayam Arab Umur 22-28 Minggu pada Suhu Kandang yang Berbeda
Abstrak: The production and quality of Arab chicken’s egg are influenced by the quality of parent stock, feed, and also environment. The aim of this research was to determine the production level, and egg quality of chicken’s egg from Arab chicken age 22-28 weeks at different level of temperatures. The experimental design used was completely randomized design (CRD) with three different level of temperatures as the treatment (netral, hot, and environment). The repetition was did 2 times. The results obtained at netral (24,7 oC), hot (27,9 oC), and environment (27,4 oC) temperatures were henday (43,6 ± 16,3 %; 39,3 ± 12,6 %; 26,3 ± 10,9 %), egg’s weight (37,60 ± 3,19 gram; 37,95 ± 3,20 gram; 37,83 ± 4,03 gram), egg’s shape index (0,79 ± 0,19; 0,78 ± 0,04; 0,78 ± 0,06), cleanliness (30,3 ± 31,7 %; 29,4 ± 26,0 %; 21,4 ± 30,4 %), eggshell’s weight (5,14 ± 0,51; 5,28 ± 0,53; 5,20 ± 0,65), eggshell’s thickness (0,29 ± 0,03; 0,30 ± 0,03; 0,30 ± 0,03), haugh unit of albumin (83,94 ± 7,96a; 84,05 ± 7,68a; 78,94 ± 9,09b), albumin’s weight (20,73 ± 2,53; 20,70 ± 2,35; 20,71 ± 2,50), indeks of yolk (0,46 ± 0,04; 0,45 ± 0,03; 0,45 ± 0,04), yolk’s weight (10,78 ± 1,84; 10,83 ± 1,34; 11,13 ± 1,80), and the colour of yolk (6-10; 4-10; 5-10).

Judul: Economic Flood Losses in the Tamansari  Persada Bogor
Abstrak: Provinsi Jawa Barat menjadi provinsi dengan frekuensi kejadian bencana alam tertinggi di Indonesia selama periode 2021, salah satu bencananya adalah banjir. Kelurahan Cibadak merupakan salah satu daerah di Kota Bogor yang sering dilanda banjir akibat meluapnya Situ Cibadak. Kerusakan yang terjadi akibat banjir tersebut menyebabkan kerugian ekonomi pada masyarakat. Dalam kurun waktu satu tahun, banjir di daerah ini bisa terjadi hingga sepuluh kali. Pemerintah harus melakukan program yang bertujuan untuk mengurangi kerugian akibat banjir. Salah satu program yang saat ini dilakukan oleh pemerintah adalah normalisasi Situ Cibadak. Penelitian ini bertujuan untuk mengestimasi nilai kerugian ekonomi masyarakat akibat banjir baik langsung maupun tidak langsung dan menganalisis pengaruh program normalisasi terhadap dampak banjir. Penelitian ini menggunakan metode Stage Damage Function untuk mengetahui hubungan antara karakteristik banjir dan faktor sosial ekonomi dengan kerusakan akibat banjir, Cost of Illness untuk menghitung jumlah biaya pengobatan yang dikeluarkan, serta Loss of Income untuk mengetahui nilai pendapatan yang hilang. Hasil penelitian menunjukkan jumlah kerugian ekonomi langsung akibat banjir pada bulan Juni 2022 adalah sebesar Rp 1.495.626.648. Kerugian ekonomi tidak langsung yang terdiri dari biaya pengobatan dan hilangnya pendapatan sebesar Rp 52.650.805. Normalisasi yang dilakukan berupa pengerukan sampah dan sedimen serta pemasangan sheet pile pada Situ Cibadak. Program normalisasi memengaruhi potensi penurunan kerugian yang dapat dilihat dari penurunan kedalaman banjir setelah normalisasi., West Java Province is the province with the highest frequency of natural disasters in Indonesia during the 2021 period, one of the disasters is flooding. Cibadak Village is one of the areas in Bogor City that is often hit by floods due to the overflow of Situ Cibadak. The damage caused by the flood caused economic losses to the community. Within one year, flooding in this area can occur up to ten times. The government must carry out programs aimed at reducing losses due to flooding. One of the programs currently being carried out by the government is the normalization of Situ Cibadak. This research aims to estimate the value of community economic losses due to flooding, both directly and indirectly, and to analyze the effect of the normalization program on the impact of flooding. This research uses the Stage Damage Function method to determine the relationship between flood characteristics and socio-economic factors with flood damage, Cost of Illness to calculate the amount of medical costs incurred, and Loss of Income to determine the value of lost income. The research results show that the total direct economic loss due to flooding in June 2022 is IDR 1,495,229,999. Indirect economic losses consisting of medical costs and loss of income amounted to IDR 52,650,805. The normalization carried out took the form of dredging rubbish and sediment as well as installing sheet piles at Situ Cibadak. The normalization program influences the potential for reducing losses which can be seen from the decrease in flood depth after normalization.
