Judul: Analisis perubahan ruang terbuka hijau dan strategi pengembangannya di Kota Bandar Lampung:
Abstrak: Development of Bandar Lampung City has the great influenced to the land use changes. Land use conversion commonly happen on Green Open Space (GOS) into other usages. The aims of this research are : (a) to identify GOS change in Bandar Lampung City along the year 2000-2007; (b) to identify GOS needed base on regulation of spatial planning (UU No 26/2007) and number of population; (c) to identify center of GOS change into built up area related to the regional development and the factors that affected the change; (d) to identify divergency of GOS change in RTRW (Public Document of Regional Planning); and (5) to find the strategy to maintain and develop GOS. This research was conducted by Landsat analysis using Geographic Information System (GIS) and combined with Location Quotient Analisys (LQ) to analize GS change. Scalogram and regression analysis used for analize the regional development and the factors that affected the GOS change. The result showed that forest, mixed dry farming, plantation and paddy field decrease of 1.449 Ha (7.35%) in 7 years, since year 2000 to 2007. Meanwhile, built up area increase to 1.218 Ha (6,19%). Based on UU No 26/2007, availability of GOS in Bandar Lampung City are still sufficient (> 30%), it’s about 61.40% (12.110 Ha) from the total area of the city. Analysis of GOS needed based on area found that in subdistrict level at Tanjung Karang Pusat and Kedaton subdistrict insufficient GOS. Based on standard for number of population, Tanjung Karang Pusat, Kedaton and Teluk Betung Selatan subdistrict still in below standard. The changes center of GOS in Bandar Lampung City happen in 63 villages, which are distributed in hierarchy III 79,57 % villages, hierarchy II 16,60% village, and hierarchy I 3,83% village. There are 2 factors that affected GOS change, one is village development index and another is number of population. Land use change from GOS and protection area into built up area was found as deviation of RTRW. The strategy to maintain and to develop GOS depend on the availability and the problem that occur with GOS, so GOS can be developed optimally.

Judul: Determination of Green Open Space Priority based on Urban Heat Island in Bandar Lampung Area
Abstrak: Tingginya laju urbanisasi yang didorong oleh meningkatnya populasi penduduk tiap tahun, terjadi di wilayah Kota Bandar Lampung. Peningkatan populasi tersebut akan berdampak pada konversi lahan kawasan vegetasi menjadi lahan pemukiman. Ketidakseimbangan antara kawasan vegetasi dan pemukiman, akan memengaruhi perubahan suhu yang memicu pertumbuhan Urban Heat Island (UHI). Penelitian bertujuan memberikan rekomendasi lokasi prioritas dalam pengembangan ruang terbuka hijau sebagai upaya mengurangi efek fenomena UHI. Metode yang digunakan bersifat kuantitatif-deduktif menggunakan analisis remote sensing dari citra Landsat 8. Hasil analisis spasial dari penentuan prioritas ruang terbuka hijau menunjukkan nilai NDVI sebagai aspek biologis yang cenderung tinggi pada wilayah sekitar urban sebesar 0,51-0,82 di tahun 2021. Aspek fisik yang dilihat dari Land Surface Temperature yang mengalami peningkatan sebesar 0,8 °C di tahun 2015 menuju 2018, penurunan sebesar 2,6 °C di tahun 2018 menuju 2021. Aspek sosial dilihat dari pertambahan penduduk yang meningkat sebesar 2,16% selama 7 tahun. Hasil penggabungan antara 3 aspek biologis yaitu NDVI, fisik yaitu LST, dan sosial yaitu kepadatan penduduk menghasilkan nilai MOORA tertinggi sebesar 7,2%, menunjukkan wilayah prioritas utama penambahan RTH sebesar 415 Ha terletak di Kecamatan Tanjung Karang Timur., The high urbanisation rate, driven by the increasing population every year, occurs in the Bandar Lampung City area. The increase in population will impact the conversion of vegetated area into residential area. The imbalance between vegetation and the residential regions will affect temperature stability which triggers the growth of Urban Heat Island (UHI). This study aims to determinate the priority locations in the development of green open spaces as an effort to reduce the effect of the UHI phenomenon. This study delivers spatial information related to the UHI phenomenon. The research method is deductive-quantitative using remote sensing analysis from Landsat 8 imagery. The spatial analysis results of the determination of green open space priorities show that the NDVI value as a biological aspect tends to be high in urban, from 0.51-0.82 in 2021. The physical part of the Land Surface Temperature has increased by 0,8°C from 2015 to 2018, and decreased by 2,6°C from 2018 to 2021. The social aspect looked at population growth with an increase of 2.16% for seven years. Combining these three aspects, NDVI as a biological aspect, LST as a physical aspect, and population growth as a social aspect get results in the highest score of MOORA with the value of 7,2% in the main priority areas for the addition of 415 Ha of green open spaces is located in the Tanjung Karang Timur District.

Judul: Diteksi antibodi anti-escherichia coli K99 dalam kolostrum induk sapi friesian holstein post vaksinasi escherichia coli polivalen dengan teknik elisa
Abstrak: Penelitian ini bertujuan untuk mendeteksi adanya antibodi terhadap Escherichia coli (E. coli) K99 di dalam kolostrum sapi Friesian Holstein (FH) yang divaksin dengan vaksin E. coli polivalen. Vaksinasi terhadap enam ekor induk sapi dilakukan sebanyak 3 kali yaitu pada 8, 6, dan 4 minggu sebelum induk diperkirakan melahirkan. Deteksi antibodi dilakukan menggunakan teknik ELISA dengan metode tidak langsung. Hasil pengamatan menunjukkan bahwa antibodi terhadap E. coli dapat dideteksi di dalam kolostrum hasil pemerahan ke-1 sampai dengan ke-9. Konsentrasi kolostrum ke-1 sampai ke-3 berkisar antara 1,054-1,129 μg/100μl. Konsentrasi antibodi tertinggi terdapat di dalam kolostrum hasil pemerahan pertama, yaitu sebesar 1,129±0.005 μg/100μl. Hasil penelitian ini dapat disimpulkan bahwa induk sapi bunting trimester akhir yang divaksin dengan vaksin E. coli polivalen mampu memproduksi antibodi spesifik terhadap E. coli K99 di dalam kolostrum dari kolostrum hasil pemerahan ke-1 sampai ke-9 dengan konsentrasi IgG total yang makin menurun pa
