Penelitian ini bertujuan untuk mengetahui pengaruh pemberian minyak Mandar yang ditambahkan bubuk daun sukun (Arthocarpus altilis) terhadap penurunan kadar kolesterol mencit (Mus musculus). Penelitian ini adalah penelitian eksperimen dengan menggunakan rancangan acak kelompok yang terdiri dari 4 perlakuan dan 5 ulangan, Kelompok 1 yaitu kelompok mencit hanya diberi pakan standar (kontrol negatif), kelompok 2 adalah kelompok mencit diberi pakan kolesterol (kontrol positif), kelompok 3 adalah kelompok mencit diberi pakan standar dan minyak mandar, dan kelompok 4 adalah kelompok mencit diberi pakan standar dan minyak ditambahkan bubuk daun sukun. Kadar kolesterol di ukur sebanyak 3 kali yaitu setelah masa adaptasi, 2 minggu setelah pemberian minyak, dan 2 minggu setelah pemberian pakan kolesterol. Hasil analisis data menunjukkan bahwa tahap awal kadar kolesterol semua perlakuan tidak berbeda nyata terhadap kontrol negatif. Namun, pada tahap akhir menunjukkan minyak yang diberi bubuk daun sukun tidak berbeda nyata dengan kelompok kontrol negatif. Kesimpulan penelitian ini adalah penambahan bubuk daun sukun (Arthocarpus altilis) (0,9 gram) pada minyak goreng olahan tradisional asal Mandar memberikan pengaruh terhadap kadar kolesterol mencit (Mus musculus).

Penelitian ini bertujuan untuk mengetahui efek tonikum pada mencit dan menentukan pada konsentrasi berapa dapat memberikan efek tonikum yang optimum. Hasil penelitian ini menunjukkan bahwa Ekstrak Daun Ceguk (Quisqualis indica L.) pada konsentrasi 5% b/v, 10% b/v dan 15% b/v pada metode ketahanan berenang menunjukkan efek tonikum pada mencit (Mus musculus). Ekstrak Daun Ceguk pada konsentrasi 15% b/v menunjukkan efek tonikum yang paling baik pada mencit dengan menggunakan metode ketahanan berenang, tetapi efeknya masih lebih kecil daripada pemberian kafein sebagai pembanding.

Abstract. The emphasis on the growth of Phytophthora palmivora was important in order to reduce Pod Rot Disease of cacao (Theobrorna cacao L.) which could harm agriculture sector. Some bacteria had chitinolytic enzyme activity that is potentially used as an antifungal against Phytophthora palmivora, because the cell wall of the fungi composed of chitin. The purpose of this research was to know chitinolytic bacteria from Perna viridis shell which had higher activity of chitinase enzyme, the amount of chitinase enzyme activity of each selected isolate, and to know the effect of chitinolytic bacterial isolates from Perna viridis shell to reduce the growth of Phytophthora palmivora. The bacteria were isolated from Perna viridis shell at Depok Beach, Kretek, Bantul, Yogyakarta. This research was an explorative research which include bacterial characterization and experimental research which include antagonistic test of chitinolytic bacteria against Phytophthora palmivora. The chitinolytic bacteria was isolated using selective chitin agar medium by pour plate method and then screening the isolates that had chitinase enzyme activity by measuring the enzyme activity of each bacterial isolates by spectrophotometric method. Selected bacterial isolates were characterized by macroscopic, microscopic and physiological characters. The bacteria that had been selected tested for their ability to reduce the growth of Phytophthora palmivora by Kirby Bauer modification method. The result showed that there were 10 isolates that had chitinase enzyme activity which two selected isolates had the higher chitinase enzyme activity. There were 7D and 6B isolates. The isolate 7D had 1,258 u/ml chitinase enzyme activity and isolate 6B had 1,212 u/ml chitinase enzyme activity. The result of chitinolytic bacterial antagonist test on Phytophthora palmivora growth showed that both bacterial isolates were potential to antifungal Phytophthora palmivora and showed a real effect in inhibiting the growth of Phytophthora palmivora with significance value < 0,05.Keywords: Chitinolytic Bacteria, Perna viridis, Phytophthora palmivora

Abtract. The study aimed to determine the effect of different meatball enhancers on meatbel protein and to determine the effect of different meatball enhancers against meatball water content. This research was conducted in june 2018 at the Laboratory of the Faculty of Agriculture, Animal Husbandry and Fisheries of the University of Muhammadiyah Parepare. Research using broiler chicken meat, water, flavorings, garlic, pepper, salt, egg white, carrageenan, gelatin, tissue, and ice cubes. The study used a completely randomized design (CRD) with four treatment levels and three replications, namely T0 = without ingreadients, T1 = crisp egg white, T2 = crustacean, T = gelatin. The results of the study showed that with the addition of pulses that the protein content of meatballs had a very real effect and water content in meatball with the addition of different ingredients that are influential real to meatball water content. The highest average protein value to the lowest is T0 is 6.52, T2 is 6.46, T1 is 6.33, T3 is 4,15. The highest average water volues to the lowest were T1 at 63.35, T0 at 63.05, T3 at 62.58, and T2 at 62.44. From the results of the study, it is known that the best treatment and can be recommended is T2 treatment with karagenan crusher.Keywords: Proteins, water content, broiler chicken meat, egg white, carrageenan, and gelatin.

Abstract. This study investigated a natural acid-base indicator which is extracted from plants in Kupang city. There are 14 plants that potential as a source of natural indicator for acid base titration, i.e, KolUngu (Brassica oleracea Capitata Group), Turi Merah flower (Sesbania grandiflora L. Pers), BelimbingWuluh flower (Averhoa bilimbi L), Kaktus Merah fruit (Opuntia vulgaris Mill), Ruelia flower (Ruellia simplex), Flamboyan flower (Delonix regia), bugenvil flower (Bougainvillea spectabilisWilld.), Bayam Merah leaves (Amaranthus tricolor L.) Jamblang fruit (Syzygiumcumini L.), Murbey fruit (Morus alba L.), Pinang fruit (Areca catechu L.), Sirih fruit (Piper betle L.), Kunyit (Curcuma longa Linn), and Nanas Kerang leaves (Rhoeo discolor). Plants extract shows a sharp color change in acid and base solution. Promising results as a natural indicator also shown in acid base titration which is have similar equivalent point to synthetic indicator. We can use these natural indicators as an alternative to synthetic indicator because they are found to be simple, very useful, cheap, easy to extract, accurate, and eco-friendly. Keywords: plant, natural indicator, acidbase.

This research is included of Queasy Experimental research with post test group only design where class VII.7 as 1st experiment and class VII.8 as 2nd experiment class. This research is done in three times of learning process meeting and once evaluation test. Taking data is done by using the test of biology studying result and then analyzed descriptive and inferentially. The result is average value in the 1st experiment class is 62,35 and forÂ 2nd experiment class is 72,38 and after hypothesis test is done with using t-test, so obtained thitung is 2,81 and ttabel 1,99. This result shows that there is difference of result studentâ€™s biology studying between the using of exchange couple type of cooperative learning model with STAD (Student Team Achievement Division) type of cooperative learning model, where the result of studentâ€™s studying that use STAD type of cooperative learning model is higher than exchange couple type of cooperative learning model. Â Keywords: exchange couple type of cooperative learning model, STAD (Student Team Achievement Division), result of studying.
