Desa Nggorang, Kecamatan Komodo, Maggarai Barat merupakan daerah yang cukup ideal untuk pengembangan ternak dan pemanfaatan limbah pertanian karena didukung oleh beberapa faktor antara lain daya dukung wilayah tempat sumber air yang ada dapat memenuhi air masyarakat kebutuhan sepanjang tahun dan ketersediaan limbah pertanian jerami padi. Tujuan dari pelaksanaan pelatihan pemrosesan pakan amoniase adalah untuk memaksimalkan produktivitas peternakan sapi dengan memanfaatkan ketersediaan sumber daya alam sambil memberdayakan limbah pertanian jerami padi sebagai sumber pakan utama dengan memanfaatkan teknologi pemrosesan pakan. Oleh karena itu, pelatihan teknologi pengolahan pakan jerami telah menjadi limbah pertanian terbesar di Desa Nggorang. Berdasarkan hasil kegiatan yang ada, ada peningkatan pemahaman petani yang dicapai. Dengan demikian desa Nggorang diharapkan mampu meningkatkan kemandirian masyarakat desa melalui kelompok tani mitra yang mampu mengoptimalkan produktivitas ternak melalui kemandirian dan kecukupan pakan ternak di Desa Nggorang, Kecamatan Komodo, Manggarai Barat, NTT  Kata Kunci: Agrowisata, Amoniase, Nggorang, Komodo

This study aims to evaluate the ability of lactic acid bacteria isolated from Sumba horse milk as a starter in improving the quality of rice straw silage. Determination of the quality of rice straw silage through organoleptic tests, measurement of percentage of silage damage and silage pH. there are 7 treatments based on silage compositions and lactic acid bacteria. The results showed the presence of golden color in all treatments as the original color, the texture was very soft to soft and not slimy, and the presence of a distinctive silage odor or close to the typical smell of silage in all treatments. The presentation of silage damage to rice straw in the positive control group showed the highest percentage of damage that was equal to 43.58%, while the percentage of damage in the treatment group ranged from 28.57% to 41.02%. The pH results showed the control group had a pH of 3.6 and the P1-P6 group had an average pH ranging from 5.7 to 6.5. The addition of lactic acid bacteria in the manufacture of silage in rice straw provides good quality silage results.

Paraquat dichloride has been used by farmers as a herbicide to kill the grass. On the other hand, paraquat dichloride is harmful if enters to the body, causing Parkinson's disease, since it is disrupting dopamine production in the substantia nigra pars compacta or dopamine pathways Nigro striatal pathway. The study was done to fi nd out the histological changes of catecholaminergic neurons and Nigro striatal pathway caused by paraquat dichloride treatment in Wistar rats as a model of Parkinson's disease.Twenty-two Wistar rats 3,5 months old were divided into 4 groups, 5 rats each. Group I (control group) were injected with aquabidest, while groups II, III, and IV were injected intraperitoneally with paraquat dichloride in aquabidest, with the dosage 5 , 10 and 15 mg/kg bw respectively. The rats were injected once per week for 6 weeks. Three days after the last injection, the rats were anesthetized using xylasin (2 mg/kg) and ketamine (20 mg/kg) intramuscularly, and then were intracardiac perfused using physiological saline as prerinse solution, followed by 10% buffered formalin solution as a fi xative. After animals were fi xed, the brains were removed and embedded in paraffi n block and cut in 12 μm thickness for immunohistochemistry staining using tyrosine hydroxylase antibody. The results of staining then were observed under light microscope and analyzed descriptively.The results showed that the catecholaminergic neurons were distributed in the substantia nigra pars compacta in all treatment groups, however, the cell density were found decreased only in group IV. Catecholaminergic neurons appear in the bipolar and multipolar form, while dopamine 'Nigro striatal pathway' was found exist in all treatment groups. From our study, histologycally the decreased of catecholaminergic neurons is only found in rats that received paraquat dichloride in dose 15 mg/kg bw for 6 weeks.

Acalypha indica Linn is a tropical weed, grows annually in East Nusa Tenggara. The weed is member of Euphorbiaceae family, a largest plant family known as medicinal plant. The weed leaves were used by local people in NTT to treat wounds, diseases or myasis on their livestock. This study aim to investigate the secondary metabolites in A. indica L leaves as a scientific proven for its local use.  The extract preparation comprises of several steps, i.e collection of fresh leaves, dry and wet sortation. The clean leaves were air dried in a room temperature for about 2 weeks before grounded into powder and subjected to extraction. The extraction method was maceration with ethanol 96% as solvent. The dense extract was evaporated using rotary evaporator and subjected to phytochemical screening. The result shows that ethanol extract of A.indica leaves were tested positive for flavonoid and tannin. Alkaloid, saponins, triterpenes and steroid were tested negative on the extract.
