Penelitian ini bertujuan untuk mengembangkan e-moduldengan pendekatan kontekstual pada materi bilangan bulat SMP kelas VII. Jenis penelitian yang digunakan adalah Research and Development. Pada penelitian ini menggunakan model pengembangan ADDIE dimana dalam tahapannya terdiri dari lima tahapan yaitu analysis, design, development, implementation, evaluation.Sebelum di uji cobakan e-modulterlebih dahulu di validasi oleh ahli media dan ahli materi. Selain itu juga ada angket tanggapan siswa mengenai media tersebut. Hasil dari validasi ahli media, ahli materi, dan angket tanggapan siswa berkriteria sangat baik dan layak digunakan sebagai media pembelajaran. Perhitungan analisis akhir dengan mengunakan uji-t pihak kanan, diperoleh rata-rata kelas eksperimen dan kelas kontrol. Berdasarkan analisis akhir dengan menggunakan uji-t pihak kanan, diperoleh nilai   yaitu 3.8963 > 2 maka H0ditolak, artinya rata-rata nilai kelas eksperimen lebih baik daripada rata-rata nilai kelas kontrol. Hal ini ditujukkan dengan perolehan rata-rata kelas eksperimen sebesar 78.75 dan kelas kontrol sebesar 65.2, artinya e-moduldengan pendekatan kontekstual pada materi bilangan bulat efektif digunakan saat pembelajaran. berdasarkan data tersebut dapat disimpulkan bahwa pembelajaran yang menggunakan e-moduldengan pendekatan kontesktual pada materi bilangan bulat SMP kelas VII layak (valid) digunakan dan rata-rata hasil belajar siswa yang menggunakan e-moduldengan pendekatan kontekstual lebih baik daripada siswa yang tidak menggunakan e-modul dengan pendekatan kontekstual.

The study aimed to determine which substrate and nutrition that gives the best result in improving growth and yield of Capsicum frutescens. The study design using CRD (completely randomized design) with two factors, namely substrates (6 levels: charcoal husks, fractional tiles, fractional bricks, arenga fiber, beach sand, husk steamed) and nutrition (2 levels: standards, standards with NPK). The study was conducted October 2015 until March 2016 in screen house Faculty of Agriculture, Sebelas Maret University. Data were analyzed using analysis of variance and if significant difference continued with DMRT (Duncan Multiple Range Test) level of 5%. The results showed that the kinds of substrates significantly affect all variables of Capsicum frutescens (plant height, leaf number, branch number, total interest, diameter trunk, root length, root volume, fresh weight of plants, plant dry weight, fruit weight and number of fruit), and the addition of NPK nutrition significantly affect variable leaf number, branch number, and fresh weight of plants.

Soybean is the basic material for any kind of industry, such as tofu and tempeh industries. Soybean cultivation will be better if use a sustainable agricultural system, such as using organic fertilizers. This research purpose was to find out the effect of organic fertilizer on the growth and yield of local soybean. The research used a complete randomized design with one factor which was a variety of organic fertilizers with 6 treatments. Various fertilizers used in this research consist of inorganic fertilizer, liquid organic, compost, cow manure, rabbit urine, chicken manure, and goat manure. Each test unit consists of 4 pots (plants) and each was repeated 4 times. The results showed that the provision of compost and goat manure increased the growth of local soybean plants, include plant height and the number of leaves at 42 DAP and leaf area at 28 DAP. The application of various organic fertilizers (liquid fertilizer, compost, cow manure, goat manure, and rabbit urine) is unable to increase the yield and yield components of local soybeans.

The flowering of shallot is influenced by low temperature and difference temperature between day and night. In Indonesia, to flowering shallot in low temperature are possible by planting in highlands. Because of climate change, the temperature difference in the highlands is very pronounced. This study aimed to determine the percentage of flowering and True Shallot Seed (TSS) production of three shallot varieties grown in the highlands. The research was conducted at Pancot Village, Tawangmangu, Karanganyar, Indonesia. The elevation of research site was 1, 300 m asl. The research design used was Split Plot with three replications. The main plot was variety: Bali Karet, Bali Lancur, and Bima Brebes. The subplot was fertilizers composition (Manure, ZA, SP36, KCl) and gibberellins: farmer’s dose (100% Inorganic and Organic) (P1G0), 100% Inorganic and Organic + Gibberellin 50ppm (P2G1), 50% Inorganic and 150% Organic (P3G0), 50% Inorganic and 150% Organic + Gibberellin 50ppm (P4G1), 200% Organic (P5G0), 200% Organic + Gibberellin 50ppm (P6G1). The results showed that fertilizer composition + gibberellins and varieties did not have significant effect on percentage of flowering, number of flowers and percentage of TSS formation. Fertilizer composition + gibberellins just influenced the number of TSS per stalks. Bima Brebes variety with P6G1 was able to flowering at 65 DAP with the flowering percentage reaching 88.87%.
