Judul: Pengaruh pemberian ampas kunyit (Curcuma ransum) dalam ransum terhadap performa produksi, respon imun dan kadar kolesterol plasma darah mencit putih (Mus musculus)
Abstrak: This research was conducted to investigate the effect of tumeric waste (Curcuma domestica) in mice diet (Mus musculus) to evaluate performance production (feed consumption, average daily gain and feed conversion), immune response (amount of leucocyte, lymphocyte and neuthil concentration), and cholesterol and trygltcerida concentration in blood plasma. Fourty eight of mices four weeks old (24 male and 24 female) were used in this reserach using different levels of Curcuma domestica waste in the ration.

Judul: Pengaruh Pemberian Salep Fraksi Etil Asetat Rimpang Kunyit (Curcuma longa Linn.) terhadap Persembuhan Luka Mencit (Mus musculus albinus) Hiperglikemik
Abstrak: The aim of this research was to know the effect of turmeric (Curcuma linga Linn.) etil asetat fraction ointment in wound healing of hiperglicemic mice (Mus musculus albinus). Thirty mice were infected with 40 mg/kgbw of streptozotocin to induced hiperglicemic. Mice were divided into three groups, which were negative control without treatment, positive control was treated with the comersil ointment and the group with the etil asetat turmeric rhizomes fraction ointment treatment. Mice were wounded by scalpel blade on the their dorsoanterior skin of mice around 1.5 cm. The pathology-anatomy of the wound healing procces were observed everyday with wound size, wound colour, wound exudation, and scab formation as the parameter. The histopathology lesion were observed on the 2nd, 4th, 7th, 14th, and 21th days after skin incision. The parameter on the histopathology observation are number of polymorfonuclear cell (neutrofil), macrophag, neovascullary formation, the precentation of wound reepitelization and the percentation of collagen connective tissue. The histopathology observation of etil asetat turmeric rhizomes fraction ointment had anti inflamantory activity as well as neovascularization and reepithelization were faster than the other groups.

Judul: Mapping of Coastline Changes in the Coastal of Bantul Regency Using Sentinel-2A Satellite Imagery
Abstrak: Pesisir merupakan wilayah yang kompleks akibat interaksi darat dan laut sehingga mudah mengalami perubahan secara fisik seperti perubahan garis pantai. Perubahan garis pantai penting diketahui untuk kajian pengelolaan kawasan pesisir, pemodelan pesisir, studi akresi-abrasi, serta analisis wilayah bahaya. Penelitian bertujuan memetakan dan menghitung laju perubahan garis pantai di Kabupaten Bantul, Daerah Istimewa Yogyakarta menggunakan citra Sentinel-2A pada tahun 2017, 2018 dan 2021. Metode digital shoreline analysis system (DSAS) digunakan untuk menghitung perubahan garis pantai secara statistik maupun geospasial. Lokasi penelitian terbagi menjadi 15 sub-zona dimana abrasi tertinggi terjadi pada Desa Parangtritis bagian timur (Sub-zona E3) dengan laju perubahan garis pantai mencapai -10,03 m/tahun. Abrasi dipengaruhi landainya kondisi pantai, gelombang dengan tinggi mencapai 2,39 m dan arus dengan kecepatan mencapai 0,24 m/s yang menggerus garis pantai serta tidak adanya penghalang di kawasan pantai. Akresi tertinggi terjadi di Desa Parangtritis bagian barat (Sub-zona E1) dengan laju perubahan garis pantai mencapai 9,20 m/tahun. Akresi dipengaruhi material sedimen dari darat yang mengendap dan menambah area garis pantai serta bergeraknya pasir oleh angin di sekitar gumuk pasir., Coastal is a complex area due to land and sea interactions so that it is easy to experience physical changes such as changes in coastlines. Coastline changes are important to know for coastal area management studies, coastal modeling, accretion-abrasion studies, and hazard area analysis. The study aimed to map and calculate the rate of change in coastlines in Bantul Regency, Yogyakarta Special Region using Sentinel-2A imagery on 2017, 2018 and 2021. The digital shoreline analysis system (DSAS) method used to calculate shoreline changes statistically and geospatially. The research location divided into 15 sub-zones where the highest abrasion occured in east Parangtritis Village (E3 sub-zone) with a coastline change rate of -10,03 m/year. Abrasion influenced by gentle coastal conditions, waves with a height of 2.39 m and currents with a speed of 0.24 m/s which erodes the coastline and there is no barrier in the coastal area. The highest accretion occurred in west Parangtritis Village (E1 sub-zone) with a coastline change 9,20 m/year. Accretion influenced by sedimentary material from land that settled and added to the coastline area and the movement of sand by the wind around the sand dune.
