Abstract

Penelitian ini bertujuan untuk mengetahui Pengaruh Jarak Tanam Legowo dan Aplikasi Kompos Jerami Terhadap Serapan Hara K, Pertumbuhan, dan Hasil Tanaman Padi (Oryza sativa L.)Varietas Inpari 19 di Kecamatan Sukra- Indramayu.Penelitian dilaksanakan di Desa Sumuradem Timur Kecamatan Sukra Kabupaten Indramayu Propinsi Jawa Barat.Waktu penelitian dilaksanakan pada bulan Juni sampai dengan bulan Oktober 2013.Metode percobaan menggunakan metode eksperimen dengan Rancangan Acak Kelompok (RAK) pola faktorial, perlakuan terdiri dari dua faktor dan diulang tiga kali.Faktor yang pertama merupakan Sistim Tanam Legowo yang terdiri dari tiga taraf (legowo 2, 3, dan 4).Sedangkan faktor yang kedua adalah aplikasi kompos jerami yang terdiri dari empat taraf (2, 4, 6, 8 ton/Ha). Hasil penelitian menunjukan adanya interaksi antara Sistim Tanam Legowo dan aplikasi kompos jerami terhadap tinggi tanaman per rumpun umur 7  Minggu Setelah Tanam, jumlah anakan per rumpun umur 7, 9, dan 11 MST, panjang malai, jumlah bulir padi per malai, dan gabah kering panen per petak. Terdapat pengaruh mandiri pada tinggi tanaman per rumpun umur 9 dan 11 MST, dan jumlah malai per rumpun. Perlakuan Sistim Tanam Legowo 2 : 1 dan aplikasi kompos jerami 8 ton/ha menunjukkan hasil tertinggi pada gabah kering panen per petak yang menghasilkan 8,37 kg/petak atau setara dengan 11,16 ton/ha.

The behavior of the farmers to using the fertilizer could be influenced by some factors. The factors such as social environment, culture, agriculture differentiate the way of using intensity the fertilizer. That behavior can also be different to what fertilizer the farmers use. The study aims to identify and analyze the behavior of farmers in using intensity of the liquid fertilizer products. The research was conducted by using a survey approach through interviews and questions (questionnaire) to 100 respondents of onion farmers in Brebes District Central Java on April until May 2015. Factors affecting the using intensity were analyzed by using multiple linear regression analysis. As the result shows in this study show that the using intensity of the liquid fertilizer is influenced by the income, the experience in planting the onions, how large the land, the productivity of the onion, the cultivating season, the recommendations from other farmers, field trials, and recommendations from the fertilizer store. The implication of the study is the farmers behavior to using the fertilizer is not only influenced of rational factors but also influenced by psychosocial factors. Government efforts to educate farmers about the benefits and risks to using liquid fertilizer need involves both aspects.

Abstract

Sapi Perah adalah salah satu ternak penghasil protein hewani yang berupa daging dan susu. Permasalahan yang terjadi pada usaha ternak sapi perah di Indonesia secara umum masih dilakukan secara tradisional dengan skala usaha kecil. Tinggi rendahnya pendapatan usaha peternak sapi perah dapat dipengaruhi oleh beberapa faktor seperti jumlah kepemilikan sapi perah, harga jual ternak, jumlah produksi susu, upah tenaga kerja, harga jual susu, harga bahan pakan, faktor obat-obatan serta faktor penjualan kotoran. Penelitian ini bertujuan untuk menganalisis faktor-faktor yang berpengaruh dan yang paling berpengaruh terhadap pendapatan. Metode penelitian menggunakan metode kuantitatif dengan melakukan interview seluruh anggota kelompok tani Maju Rukun yang beranggota 17 peternak. Sumber data yang digunakan dalam penelitian ini adalah data primer dan data sekunder. Analisis data menggunakan analisis deskriptif, analisis regresi linier berganda dengan uji F dan t, serta pengujian hipotesis. Hasil penelitian menujukkan bahwa faktor jumlah sapi perah, faktor harga jual ternak, faktor upah tenaga kerja, faktor harga susu, faktor harga pakan, dan faktor harga obat obatan, berpengaruh secara signifikan terhadap Pendapatan.

Abstract

The research aims to determine; (1) the effect of the combination of spacing and dose of NPK fertilizer on the growth and yield of sweet corn, and (2) the combination of spacing and dose of NPK fertilizer that gave the best effect on the growth and yield of sweet corn of Bonanza F1 cultivar. The research was carried out for 3 (months) months, starting from September to December 2021. The method used in this study is an experimental method, using a randomized block design, 9 combination treatments of spacing and doses of NPK fertilizer and repeated three times. To determine the effect of the treatment being tested, analysis of variance was used through the F test, with further testing using the Scott Knott test at a significance level of 5 percent. The results showed: (1) Plant spacing and NPK fertilizer had a significant effect on plant height, number of leaves per plant, stem diameter, diameter of cob without stalks, length of cobs without kelobot, weight of cob without kelobot per plant and per plot, and (2) A distance of 75 cm x 50 cm and a spacing of 75 cm x 60 cm combined with the application of 300 kg/ha of NPK fertilizer gave the highest weights of cobs without husks per plot, namely 3.67 kg and 3.54 kg or equivalent to 12.23 tons/ha. ha and 11.80 tons/ha.
