Judul: Urban Forest Priority Development Based on Air Pollution Distribution and Land Temperature in Kota Jambi
Abstrak: Kota Jambi terus mengalami perkembangan dan berimplikasi pada pesatnya pembangunan. Hal tersebut dapat menyebabkan penurunan kualitas lingkungan sehingga dibutuhkan hutan kota dalam memitigasinya. Penelitian ini bertujuan untuk menentukan potensi lokasi hutan kota berdasarkan sebaran polutan udara dan suhu permukaan di Kota Jambi. Penentuan lokasi prioritas hutan kota menggunakan sebaran polutan udara dan suhu permukaan yang dikelaskan menurut kriteria lokasi prioritas, sedangkan tutupan lahan menjadi acuan dalam penentuan lokasinya. Data dikumpulkan menggunakan citra satelit Sentinel-5P berupa CO, NO₂, O₃ dan SO₂, sedangkan nilai suhu permukaan dan tutupan lahan dari citra Landsat 8. Semua data diolah di Google Earth Engine. Potensi lokasi hutan kota dikategorikan menjadi tiga kelas prioritas yaitu prioritas 1 dengan nilai polutan dan suhu permukaan tertinggi meliputi Kecamatan Danau Teluk, Jambi Timur dan Pelayangan; Prioritas 2 dengan nilai polutan dan suhu permukaan menengah meliputi Kecamatan Danau Sipin, Jelutung, Paal Merah dan Pasar Jambi; serta prioritas 3 dengan nilai polutan dan suhu permukaan terendah., Jambi City continues to prosper and has implicated to its rapid development. It can cause a decrease in urban environmental quality, hence the existence of urban forests is needed to mitigate such problems. This study aims to determine the potential locations for urban forests based on the distribution of air pollutants and surface temperature in Kota Jambi. Determination of priority locations uses distribution of air pollutants and surface temperature map that are classified according to priority location criteria, while land cover becomes a reference in determining its location. Sentinel-5P satellite is used for collecting CO, NO₂, O₃, and SO₂ whereas the Landsat 8 satellite is used for collecting surface temperature and land cover. The data are processed on Google Earth Engine. The potential locations for urban forests in Jambi City categorized into three priority classes, namely priority 1 with the highest pollutant and surface temperatures values which are the Danau Teluk, Jambi Timur and Pelayangan District; Priority 2 with medium pollutant and surface temperatures values includes of the Danau Sipin, Jelutung, Paal Merah, and Pasar Jambi Districts; and Priority 3 with the lowest pollutant and surface temperature value.

Judul: Prioritas Pengembangan Hutan Kota di Jakarta Selatan
Abstrak: South Jakarta is one of the densely populated municipality in DKI Jakarta. Increased urbanization causes degraded lands green space that will lead to environmental degradation such as air pollution and rising temperatures. Urban forest is one of green space that is capable of restoring the balance and healthy urban environment. Criteria in the selection of priority areas using the variable surface temperature and air pollutants and classified by three classes of priority. Urban forest priority location is the availability of green space that goes into the priority class . The results of this study indicate priority areas in the first class of 1269.86 ha ( 8.72 % ) , the second class of 7076.55 ha ( 48.61 % ) and the third class of 6210.03 ha ( 42.66 % ) . The availability of green space that was in the first priority class of 77.96 Ha , the second class of 327.57 Ha and class of 983.61 Ha . Total green space can not be found to reach 10 % of the South Jakarta areas because land limitation and convertion land use.

Judul: Kawin Berulang Pada sapi, Kausa Kuman Aspesifik Dan Pengobatannya
Abstrak: Kawin berulang pada sapi betina adalah merupakan bantuk atau geja1a inferti1itas, dimana sapi-sapi yang menderita kawin beru1ang tersebut mempunyai siklus berahi yang normal atau hampir normal dan sudah dikawinkan dua ka1i atau 1ebih dengan pejantan atau semen pejantan fertil, tapi tetap belum bisa bunting. Pemeriksaan klinis terhadap sapi tersebut tidak memberikan gambaran tertentu yang dapat menerangkan kegaga1an konsepsi yang dialami (Roberts, 1971).
