Media pembibitan merupakan faktor eksternal yang juga menentukan pertumbuhan bibit tanaman. Penelitian ini dilakukan untuk menganalisis kandungan N,P, K, porosita,s dan pertumbuhan bibit sengon Paraserianthes falcataria (L) Nielsen pada 5 macam media pembibitan. Media pembibitan dibuat dari tanah ultisol dicampur sekam padi atau serbuk gergaji dengan takaran berbeda lalu diinkubasi selama 30 hari. Hasil analisis kandungan N total  media M1 yaitu 0.18% (kategori rendah); media M2, M3, M4 dan M5, berkisar antara 0.20-0.50% (kategori sedang). Kandungan P media M1 yaitu 13.98 mg/kg  (kategori rendah); media M2, M3, M4 dan M5,  berkisar antara 26-35 mg/kg (kategori tinggi).  Kandungan K semua media berkisar antara 9.68-18.63 me/100g (kategori tinggi).  Porositas media M1= 52%; M2=66%; M3 = 84%; M4 = 75% dan M5 =71%.  Hasil analisis pertumbuhan bibit sengon P. falcataria (L) Nielsen pada 5 media pembibitan yaitu: tinggi = 12.3-17.5 cm; diameter batang = 0.65-0.85 cm; jumlah daun = 110–140 helai dan panjang akar = 9.0–14.3 cm. Media pembibitan M3 berbahan tanah ultisol 50% dan sekam padi 50% menghasilkan kandungan N sedang, kandungan P dan K tinggi, porositas tertinggi, dan menghasilkan  pertumbuhan bibit sengon P. falcataria (L) Nielsen terbaik.

Abstract

Penelitian tentang struktur komunitas mangrove asosiasi di sekitar area tambak telah dilakukan pada bulan Mei-Desember 2016 di Desa Balandatu Kecamatan Mappakasunggu Kabupaten Takalar Sulawesi Selatan. Penelitian ini bertujuan untuk mengetahui jenis, kerapatan, frekuensi, penutupan, INP, SDR (Standard Dominance Rasio), dan penyebaran mangrove asosiasi di daerah tersebut, serta membandingkan struktur komunitas mangrove asosiasi di daerah tambak dan non tambak. Pengambilan dilakukan dengan metode purposive sampling menggunakan transek sabuk di daerah tambak dan transek kuadrat di daerah non tambak. Data yang diperoleh dianalisis secara kuantitatif untuk mendapatkan nilai SDR (Standard Dominance Rasio). Data penyebaran spesies dihitung berdasarkan Indeks Morisita. Dari hasil pengambilan data diperoleh 36 spesies mangrove asosiasi dari 22 familia, terdiri dari 11 spesies (7 familia) di daerah tambak dan 26 spesies (19 familia) di daerah non tambak. Nilai SDR tertinggi dari 5 stasiun di daerah tambak terdapat di stasiun 1 ditemukan pada rumput Fimbristylis cymosa dengan nilai 100%, sedangkan di daerah non tambak nilai SDR tertinggi ditemukan di stasiun 3 pada semak Kirinyu Eupatorium odoratum dengan nilai 75,48 %.  Mangrove asosiasi umumnya memiliki pola penyebaran mengelompok. Dapat disimpulkan bahwa mangrove assosiasi di daerah non tambak dan tambak memiliki struktur komunitas berbeda dengan penyebaran mengelompok. Kata kunci: Struktur komunitas, mangrove asosiasi, Desa Balandatu, Tanakeke, Sulawesi Selatan

Abstract

Actinomycetes is one type of microorganism that has been widely used for the production of antibiotics as well as a biological control for pests and diseases in plants. In general, many Actinomycetes distributed in soil, water, tissues endophyte, and other natural environments. The study aimed to determine the distribution and diversity of Actinomycetes found in the root zone at Solanaceae plants and to know the isolates of Actinomycetes isolated from the root zone of plants Soalaneceae could inhibiting the growth of bacteria. Actinomycetes isolated from seven soil samples of Solanaceae plants rhizosphere in Selo Boyolali, Colomadu Karanganyar, Gondangrejo Karanganyar, and Wonogiri Jatipurno. The isolates of Actinomycetes tested the antibacterial activity by well diffusion method on media Glycerol-Yeast Extract against four species of pathogenic bacteria Ralstonia solanacearum, Staphylococcus aureus, Bacillus subtilis and Escherichia coli. Results showed that there were 54 isolates of Actinomycetes isolated from the soil samples of Solanaceae plants rhizosphere. Isolates could inhibit the growth of R. solanacearum (29%), S. aureus (24%), B. subtillis (14%), and E. coli (7%). Isolates had the ability to degrade carbohydrate and protein.

Abstract

Industrial progress and waste of urban domestic activities have an impact on the Pb heavy metal pollution on the environment, this will have an impact on human health. Pb metal can be overcome with biological methods by utilizing bacteria in reducing Pb metal. The study aimed to obtain the species  of resistant bacterial isolates of Pb metal and determine its characteristics. Sediment and water samples were obtained from the Tallo River. Isolation and selection of Pb metal resistant bacteria were carried out on nutrient agar media is 10 ppm added of PbAgNO3, afterwards the colonies that grew and differed were characterized by morphological morphology and several biochemical tests. The characterization results obtained 8 isolates of Pb metal resistant bacteria consisted of 8 isolates from sediment samples and 3 isolates from water samples. The characteristics of each bacterial isolate on cell morphology are the same and biochemical tests show different results.

Abstract

The purpose of this study was to determine the effect of K2DAV and K3DAV animation media on learning motivation in terms of the academic abilities of students in class X MIPA SMA N 1 Sukoharjo. The focus of the biological material studied is the component material, interactions, and energy flow in the ecosystem. This research is a quasi-experimental study with a post-test-only non-equivalent group design. The population consists of 7 classes, and the sample is taken by simple random sampling of as many as three classes. Class X MIPA 1 is an experimental class with K2DAV media. Class X MIPA 3 as experimental class 2 with K3DAV media. Class X MIPA 6 as a control class. Data collection is done through documentation, questionnaires, and observations. The research instrument was a student learning motivation questionnaire and an observation sheet on implementing discovery learning syntax. The data analysis technique was carried out by testing prerequisites and testing hypotheses. The prerequisite test was carried out for normality, homogeneity, regression, and linearity. In contrast, the hypothesis test used the Anacova test. The study results explain that discovery learning combined with K2DAV and K3DAV media affects learning motivation in terms of academic ability, and academic ability affects learning motivation.
