Judul: Analisis Manfaat Sosial Ekonomi Ruang Terbuka Hijau pada Normalisasi Waduk Ria Rio Jakarta
Abstrak: Increasing flood disaster in DKI Jakarta makes the government do some efforts to increase the quality of a reservoir and its environment through reservoir normalization program. The specific objective of this study is to identify the public perception towards the normalization of Ria Rio Reservoir and the socio economic benefits of it, estimate the number of willingness to pay of people around the Ria Rio Reservoir toward the effort of preservation of the open green space around it, and identify factors that affect the value of the willingness to pay of the community toward preservation efforts of the open green space around the Ria Rio Reservoir. The results of this study indicate that people's perception of each indicator to the development of open green space around the Ria Rio Reservoir is well worth. Socio-economic benefits of the normalization of Ria Rio Reservoir which has been enjoyed by society is the park can be used as a recreation area, the park become public sports facilities, they get entertainment by fishing in the reservoir, nearby the reservoir becomes strategic for selling things as many visitors and gain employment as sweepers and garbage collectors. The average yield of willingness to pay of 61 respondents who are willing to pay is IDR 44.836,07 per month per person. Factors that affect the 10% significance level were gender, age, income level, education level, residence status, and length of stay.

Judul: Analisis kerugian ekonomi dan kesediaan membayar masyarakat dalam upaya perbaikan lingkungan perumahan (Studi kasus Perumahan Dosen IKIP, RW 02, Kelurahan Jatikramat, Kecamatan Jatiasih, Kota Bekasi)
Abstrak: RW 02 IKIP Lecture’s Housing Complex in one of the housing areas in Jatiasih District that has been affected by flood. As flood water had brought loss to the society, it takes effort to restore the residential neighborhood, to minimize the effect of flood in the future. The purposes of this study are to identify the characteristic of respondents, to estimate the economic loss, to estimate willingness to pay for environmental improvement, and to identify the factors that influence willingness to pay for the environmental improvement. This study used four methods of analyses, namely: (1) descriptive analysis, (2) damage assessment analysis, (3) willingness to pay analysis, and (4) multiple linear regression analysis. The result showed that the impact of flood in RW 02 IKIP Lecture’s Housing Complex are the disruption of activity, public health, income losses, the damage on houses and household furniture also the decreasing of housing environmental condition. Total estimated of economic loss of the society in RW 02 IKIP Lecture’s Housing Complex by flood in January to February period 2014 was as much as IDRRp1,055,129,468.20. The mean value of willingness to pay for 95 respondents, who are willing to pay for environmental improvement is IDR26,736.84 per month per household. Factors that influence the willingness to pay were education, family dependent, income, housing status, and flood elevation.

Judul: Cloning and Structure Prediction of C-Type Lectin 19 (CTL-19) from Silkworm (Bombyx mori L.)
Abstrak: Bombyx mori L. is a highly significant insect due to its silk production affects several industries. Unfortunately, B. mori farming has recently experienced mortality issues caused by pathogenic infectious diseases. Despite the extensive study of innate immunity of B. mori, information regarding the molecular functions and mode of actions of C-type lectin 19 (CTL-19) in the innate immunity of B. mori remains limited. Therefore, this study aimed to predict the structure of the B. mori CTL-19 also clone and produce the recombinant protein to better understand its role in the silkworm's innate immunity. The open reading frame (ORF) of the CTL-19 gene (945bp) was successfully amplified and cloned to pGEM®-T Easy Vector. The mature protein consists of 294 amino acids with 2 CRDs, 9 conserved cysteine, and two specific carbohydrate binding motifs. Protein threading demonstrated to be superior in order to predict the ligand binding site in comparison to homology modelling. The predicted molecular weight is 33.26 kDa, with pI value of 5.70. Furthermore, molecular docking analysis reveal that BmCTL-19 have ability to bind to various carbohydrate residues. The BmCTL-19 gene will be sub clone into an appropriate expression vector and produce purified recombinant protein to evaluate its properties.
