Abstract

The objective of this research is to know the varieties of macro invertebrate species and water quality of the rivers in Madiun. The researcher used macro invertebrate as bio indicator. The result of the study can be used as references to the people to fulfill water need. This research used bio monitoring with macro invertebrate as bio indicator. The technique which was used in this research was purposes random sampling. The samples were taken from four differences places. They were taken from the upstream, the middle of the river, and the downstream. The samples were taken once in two weeks for two months. The researcher used Family Biotic Index (FBI) to analyze the data that was supported by physic and chemistry parameter. From the research that has been done in station 1, the researcher found one hundred and fifty species, FBI: 6, 58. It meant that the water quality was bad, with the highest pollution. In station 2, the researcher found two hundreds and seventy nine species, FBI: 6, 49, it meant that water quality was bad with the high pollution. In station 3, the researcher found three hundred and forty two species, FBI = 6, 64. It meant that the water quality was bad, with the high pollution. And in station 4, the researcher found fifty one species FBI=6, 58, meant that the water quality was bad with the high pollution. Based on the macro invertebrate samples that were found in above, the researcher found t13n families were resistant to pollution.

Abstract

To achieve national education purpose, Indonesia's government provide three categories facilities, formal, non-formal, and informal education. Formal education held the Ministry of education, non-formal education organized independently, informal education in family and society. Three types education work together to achieve the national education purpose. The research purposeto determine students satisfaction level to learning Biology in formal school and non-formal learning. Analysis results of research are expected as material evaluation Organizer formal education in order to meet the needs student learning without having to rely institutions of the mentorship of non-formallearning. Research using observation method, researchers conducted bservations directly the research object to see the reality in the field. Data collected using questionnaires on 30 respondents high level school students. Questionnaire were analyzed using comparative average student learning satisfaction in formal school and non-formal learning. Student learning satisfaction measurementresults on the quality of the material, 81,6% of formal schooling and non-formal learning 87,6% , aspects method of formal school 87% and non-formal learning 75%, teaching quality aspects of formal school 79% and non-formal learning 83%, school formal infrastructure aspects of 92% and non-formal learning 76%, learning time aspects formal school 90% and non-formal learning 85%.

Abstract

This study aims to determine the quality of the river water Gandong using bio-indicators of macroinvertebrates and utilize the results of this study to be used as the building blocks of practical guidance on the subject of environmental pollution junior class VII. The study was conducted in River Gandong Village. Ringinagung, Kab. Mabopane divided into 3 stations. Data obtained from direct observations in the field and laboratory tests. The method used is descriptive qualitative approach that gives an overview of water quality Gandong River. Data were analyzed after identifying the calculating method Family Biotic Index (FBI) based on tolerance index macroinvertebrates.The results of measurements of physical and chemical parameters, such as temperature for each station in the range of 25 ° C-26, turbidity range 27-30 cm, the pH range 7, the current speed 0,16-0,29 m / s, DO 5,8-6 , 1 mg / L. Station II data has physical and chemical parameters lowest, but some aquatic biota able to survive despite the type and the amount is not much in the station I and III. As for the calculation of the FBI, the station I have the 6.39, 6.99 II station, and the station III 6.82. Water quality station I quite bad, but the quality of the station II and III declined to poor interpretation of the FBI. Family macroinvertebrates are most commonly found in every station is family Thiaridae and Physidae. The results of this study can be used as the building blocks of practical instructions Chapter Pollution Junior Class VII entitled "Observing types of animals macroinvertebrates in the river".

Abstract

Tujuan yang ingin dicapai dalam penelitian ini adalah untuk mengetahui keanekaragaman spesies makroinvertebrata dan kualitas Sungai Madiun dengan menggunakan makroinvertebrata sebagai bioindikator, sehingga hasil penelitian ini dapat digunakan sebagai dasar acuan penggunaan air Sungai Madiun dalam peruntukan kebutuhan masyarakat.Metode yang digunakan dalam penelitian ini adalah biomonitoring dengan bioindikator makroinvertebrata, teknik yang digunakan dalam mengambil sampel adalah dengan teknik purposive random sampling, sampling dilakukan di empat stasiun yaitu bagian hulu bagian tengah dan bagian hilir, pengambilan sampel dilakukan setiap 2 minggu sekali selama dua bulan.Analisis data yang digunakan adalah dengan menggunakan Famili Biotik Indeks (FBI) yang didukung oleh paramater fisik dan kimia.Dari penelitian yang telah dilakkan pada stasiun 1 ditemukan 150 spesies dengan FBI=6,58, yang artinya termasuk kategori kualitas air buruk, dengan tingkat pencemaran terpolusi sangat banyak, pada stasiun 2 ditemukan 279 spesies dengan FBI=6,49, yang artinya termasuk kategori kualitas air sangat buruk, dengan tingkat pencemaran terpolusi sangat banyak, pada stasiun 3 ditemukan 342 spesies dengan FBI=6,64, yang artinya termasuk kategori kualitas air buruk, dengan tingkat pencemaran terpolusi sangat banyak dan pada stasiun 4 ditemukan 51 spesies dengan FBI=6,58, yang artinya termasuk kategori kualitas air buruk, dengan tingkat pencemaran terpolusi sangat banyak. Dari data sampel hewan makroinvertebrata yang ditemukan tersebut di atas terdiri dari 13 famili yang sebagian besar adalah makroinvertebrata yang tahan terhadap pencemaran.

Abstract

Tujuan penelitian ini adalah untuk mengetahui (1) Pengaruh cara pemeraman yang berbeda terhadap kandungan vitamin C buah pisang Raja (2) Pengaruh lama pemeraman terhadap kandungan vitamin C buah pisang Raja (3) Adanya interaksi antara cara dan lama pemeraman terhadap kandungan vitamin C buah pisang Raja. Penelitian ini dilaksanakan di Laboratorium Biologi IKIP PGRI Madiun pada bulan Juni sampai September 2012. Rancangan penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan 2 faktorial yaitu cara pemeraman dan lama pemeraman. Cara pemeraman dibedakan menjadi daun Lamtoro (C1), Karbid (C2) dan Larutan Ethrel (C3), dan faktor lama pemeraman meliputi 0 hari (L0), 2 hari (L1), 4 hari (L2), 6 hari (L3), dan 8 hari (L4). Data penelitian ini dianalisis dengan menggunakan analisis variansi (ANAVA) ganda. Jika dalam penelitian ini didapatkan nilai F hitung > Ftabel berarti hipotesis diterima dan untuk mengetahui perbedaan tiap perlakuan dilanjutkan dengan uji Beda Nyata Terkecil (BNT) dengan taraf signifikansi 5%. Hasil penelitian menunjukkan bahwa: (1) Cara pemeraman yang berbeda berpengaruh terhadap kandungan vitamin C buah pisang raja (Musa paradisiaca L). Pemeraman dengan ethrel menghasilkan rata-rata vitamin C yang paling tinggi yaitu 8,51 mg setiap100mg larutan pisang. (2). Lama pemeraman berpengaruh terhadap kandungan vitamin C pada buah pisang raja (Musa paradisiaca L). Pemeraman pada hari ke-4 menghasilkan vitamin C paling tinggi untuk semua perlakuan yaitu 11,02mg/100mg. (3). Ada interaksi antara cara dan lama pemeraman terhadap kandungan vitamin C buah pisang raja (Musa paradisiaca L). Pada cara pemeraman dengan ethrel dan lama pemeraman 2 hari didapatkan kandungan vitamin C yang paling tinggi dan berbeda nyata dengan perlakuan yang lain.
