Judul: Sistem Akuisisi dan Pengolahan Data Citra Satelit untuk Pemantauan Perubahan Lahan Pertanian di Provinsi Jawa Barat 2000-2015
Abstrak: Jawa Barat merupakan provinsi yang mengalami alih fungsi lahan sawah terluas di Pulau Jawa sehinga perlu dilakukan monitoring dalam kaitannya dengan perubahan fungsi lahan. Metode pemantauan lahan dengan MODIS telah banyak dilakukan namun masih menggunakan lebih dari satu perangkat lunak. Penelitian ini bertujuan membangun sistem akuisisi dan pengolahan data citra yang memudahkan pengguna dalam memantau lahan. Produk MODIS yang digunakan dalam penelitian ini adalah MOD13Q1, yang memotret indeks vegetasi harian sehingga dapat menampilkan dinamika musiman untuk pola sawah. Data MODIS EVI masih mengandung gangguan atmosfer sehingga perlu dilakukan koreksi sinyal dengan filter transformasi wavelet coifflet untuk mengurangi gangguan. Kemudian dilakukan pengelompokan pola tanam dengan metode pengelompokan k-mean untuk mendapatkan kelompok yang sama pola tanam, intensitas tanam dan perubahannya. Penelitian ini menghasilkan graphical user interface (GUI) dalam software Matlab. Hasil yang diperoleh berupa peta hasil stacking, hasil denoising, serta peta hasil clustering.

Judul: Analisis Luas Lahan Sawah Berbasis Citra MODIS di Provinsi Jawa Barat Tahun 2002-2012
Abstrak: West Java is the largest province in Java Island that had been experiencing rice field land conversion since 1999. Agricultural statistic data that provide by National Statistic Agency (BPS) has several lacks in monitoring process of rice field area year to year, therefore it is required to improve other alternatives to the collected data by satellite imagery. The aims of this research were to detect rice field area based on rice field categorization in West Java derived from MODIS imagery and to obtain the differences of rice field area between MODIS imagery and agricultural statistic data of BPS from 2002 to 2012. The results showed that there were noticeable differences of rice field area in Ciamis, Bogor, Bandung, and Purwakarta districts. In West Java, rice field area during 2002 until 2010 derived from MODIS imagery were higher than those derived from agricultural statistic data of BPS.

Judul: The Effects of Hypothyroidism in the Fertility of Male Rats
Abstrak: Thyroid hormones are involved in the development and maintenance of virtually all tissues. The purpose of the study is to understand effects of the neonatal hypothyroidism in the fertility of male rats. Recent studies with juvenile rats indicate that changes in thyroid function early in life have a major impact on the endocrine and/or paracrine factors regulating testicular growth and function. However, one should keep in mind that hypothyroidism is a complex hormonal dysfunction rather than a single hormonal defect. Hypothyroidism has been also shown to reduce the secretion of GnRH (gonadotropins releasing hormone), LH (Luteinizing Hormone), FSH (Follicle Stimulating Hormone), GH (Growth Hormone) and testicular testosterone in rats. Therefore, many of the testicular changes observed in prolonged hypothyroidism could result in some degree of diminished levels of the aforementioned hormones. The transient neonatal hypothyroidism model results in the unnatural testicular development and in sperm production in neonates hence resulting in decreased fertility upon puberty.
