Abstract

DOWNLOAD PDFPenelitian ini merupakan penelitian eksperimen semu yang bertujuan untuk mengetahui pengaruh penerapan strategi  pembelajaran QSH dan kemampuan akademik awal siswa terhadap hasil belajar kognitif siswa kelas VIII SMPN 2 Camba serta pengaruh interaksi antara strategi pembelajaran QSH dengan kemampuan akademik terhadap hasil belajar kognitif siswa. Subjek penelitian ini adalah siswa kelas VIIIa sebagai kelas QSH dengan jumlah siswa 30 orang dan kelas VIIIb sebagai kelas konvensional dengan jumlah siswa 28 orang. Pengambilan data dilakukan dengan mengevaluasi hasil belajar, melalui tes tertulis yang meliputi pretest (tes hasil belajar kognitif awal siswa) dan posttest (tes hasil belajar kognitif akhir siswa). Data yang terkumpul dianalisis secara statistik deskriptif dengan menggunakan pedoman pengkategorian hasil belajar menurut Arikunto dan uji hipotesis secara inferensial dengan menggunakan analisis kovariansi (Anakova) dengan taraf signifikasi 5%. Hasil penelitian menunjukkan bahwa strategi pembelajaran diperoleh nilai p lebih besar dari α 0.05 (p≥0.05) dengan sig. 0,417, kemampuan akademik diperoleh nilai p lebih kecil dari α 0.05 (p≤0.05) dengan sig. 0,008, dan interaksi strategi pembelajaran dan kemampuan akademik diperoleh nilai p lebih besar dari α 0,05 (p≥0,05) dengan sig. 0,131. Dengan demikian, dapat disimpulkan bahwa kemampuan akademik berpengaruh terhadap hasil belajar kognitif siswa sedangkan strategi pembelajaran QSH dan interaksi antara strategi dengan kemampuan akademik tidak berpengaruh signifikan terhadap hasil belajar kognitif.   Kata kunci: Strategi pembelajaran QSH, kemampuan akademik, hasil belajar kognitif

Abstract

DOWNLOAD PDFThe drainage system in Makassar City of Indonesia is intended to efficiently deliver waste water  (stormwater and greywater)  to the  receiving waters  downstream. There is no wastewater processing plant available. Thus, waste water,  from  households and industries located in  residential areas  was delivered  directly  to  the  drainage  system.  Nutrients,  like nitrogen and phosphorus, contained in the waste water was also delivered to the receiving waters. There is no data available on how much nutrient has entered the receiving waterbodies. We conducted a survei on the concentration of total- and soluble- nitrogen and phosphorus in surface water of Sinrijala Drainage and Pampang River that drained a heavily populated area in this city in November 2009. The cadmium reduction method was used to measure nitrogen, and the ascorbic acid method for phosphorus. Our survey showed that the surface water was potentially very eutrophic at the time of sampling. The concentration of TN (0,056-3,697 mg/L), TP (3,140-13,03 mg/L), and the respective soluble species (FRP: 0,028-2,935 -NO3-N: 0,187-0,601 mg/L) were well beyond the internationally accepted levels. The probable sources of these nutrients were domestic waste like deterjent, food scrapes and human waste.   Key words:  Nutrients concentration, total nitrate, total phosphorus, nitrate-nitrogen, nitrite-nitrogen, urban drainage, Makassar.

Abstract

DOWNLOAD PDFThe aim of this research was to examine the total phenolic content and radical scavenging capacity related to antioxidant potential in different fractions of methanolic extract of mangroves trees, Sonneratia alba bark. Total phenolic content was determined by the  Folin-Ciocalteau method.  Antioxidant  potential  has  been determined  as  the  free radical scavenging ability using a stable radical, diphenyl-picryl-hydrazyl (DPPH). Three fractions  of methanol extracts of S. alba were subjected to free radical scavenging activity in order to evaluate their antioxidant activity. The free radical scavenging activity of different fractions obtained from successive fractionation of methanol extracts with organic solvents of different polarities; hexane, chloroform, and ethyl acetate. Total phenolics content of three fraction and crude extract are 17.84 ±0.974, 156.310 ±0.703, 226.89 ±0.605, 249.56  ±0942 (GAE μg/g) respectively for hexane, chloroform, ethyl acetate, and crude extracts (methanol extract). Antioxidant assay showed that the ethyl acetate and chloroform fractions have the high activity with IC50 10.27 μg/ml and 27.34 μg/ml, respectively, while  a weak activity was showed by hexane fraction with 147 μg/ml. Linear correlation between the total antioxidant capacity of the fractions and the total phenolic contents was observed (r2=0.918). This data indicated that the antioxidant activity  mainly due to phenolic compound contain in those fraction. The results indicate promising S.alba or the utilization as significant source of natural antioxidant. Key words: Sonneratia alba,  total phenolics,  radical scavenging activity, antioxidant,  DPPH

Abstract

Keberadaan Hylobates moloch (Owa Jawa) endemik di hutan-hutan konservasi seperti Taman Nasional Ujung Kulon, Gunung Halimun, Gunung Gede Pangrango, Cagar Alam Gunung Simpang, dan Leuweung Sancang, dan menurut IUCN Redlist status konservasi Owa tersebut termasuk dalam kategori endangered (genting). Penelitian bertujuan untuk mempelajari tingkah laku dan karakteristik Owa Jawa di Karantina Taman Margasatwa Ragunan (TMR). Metode kualitatif yang digunakan dalam penelitian adalah melakukan pengamatan langsung terhadap tingkah laku Owa Jawa dengan cara: a) deskripsi, b) ad libitum, c) focal sampling, dan d) scan sampling. Aktivitas harian hidup Owa Jawa yang mencakup makan dan minum, bergerak, beristirahat, serta bersosialisasi di Karantina TMR pada dasarnya mirip dengan perilaku Owa di habitat alamiahnya serta di Pusat Penyelamatan dan Rehabilitasi Owa Jawa (Javan Gibbon Center), Taman Nasional Gunung Gede Pangrango. Adanya kemiripan aktivitas harian hidup Owa Jawa mengindikasikan bahwa sudah selayaknya tidak ada alasan yang sangat mendasar dalam tata cara pemeliharaan maupun perawatan Owa Jawa di karantina TMR untuk tidak berhasil, sebaliknya harus berhasil dan berkembang menjadi lebih banyak.Kata kunci: Owa Jawa, tingkah laku, Taman Margasatwa Ragunan

Abstract

DOWNLOADGentamisin merupakan salah satu antibiotik dari golongan aminoglikosida yang sering digunakan karena harganya relatif lebih terjangkau dan efektif. Namun gentamisin memiliki efek samping terhadap berbagai organ. Efek toksik gentamisin berbagai organ dapat dinetralisir oleh antioksidan yang terdapat dalam ekstrak tanaman obat. Penelitian ini bertujuan untuk mengetahui pengaruh ekstrak jintan hitam (Nigella sativa L.) terhadap berbagai organ diantaranya hepar, paru dan testis tikus putih (Rattus norvegicus) yang diinduksi gentamisin.Penelitian menggunakan 25 ekor tikus putih jantan galur Sprague dawley. Tikus secara acak dibagi menjadi 5 kelompok yaitu K1 (aquadest), K2 (gentamisin intraperitoneal/ip 80 mg/KgBB), K3 (gentamisin ip 80 mg/KgBB+ ekstrak jinten hitam 500 mg/KgBB), K4 (gentamisin ip 80 mg/KgBB+ ekstrak jinten hitam 1000 mg/KgBB) dan K5 (gentamisin ip 80 mg/KgBB+ ekstrak jinten hitam 1500 mg/KgBB). Gentamisin diberikan selama 8 hari dan ekstrak jintan hitam selama 10 hari, lalu tikus diterminasi. Gambaran histopatologi hati, paru dan testis tikus dengan pewarnaan hematoksilin eosin diamati dibawah mikroskop dan dilakukan analisis data. Dari hasil penelitian ini dapat disimpulkan bahwa terdapat pengaruh pemberian ekstrak jintan hitam (Nigella sativa L.) terhadap gambaran histopatologi hepar, paru dantestis tikus putih (Rattus norvegicus) yang diinduksi gentamisin.
