Abstract

Penelitian ini bertujuan untuk mengetahui bagaimana pengaruh konsentrasi dan penyemprotan ZPT Atonik serta pengaruh interaksi antara keduanya terhadap produktivitas bawang merah. Penelitian dilakukan di desa Arjasa, Kecamatan Arjasa, Kabupaten Jember pada ketinggian tempat ± 141 m dpl pada bulan Juli 2010 sampai Oktober 2010. Rancangan yang digunakan adalah RAK Faktorial dengan 3 kali ulangan. Faktor pertama konsentrasi Atonik (K) terdiri dari 4 level yaitu: K1 = 0,25 cc/liter,  K2 = 0,50 cc/liter,  K3 = 0,75 cc/liter, K4 = 1,00 cc/liter. Faktor kedua interval penyemprotan (I) terdiri dari 3 aras yaitu I1 = umur 15-20-25-30 hari setelah tanam, I2 = umur 15-25-35-45 hari setelah tanam I3 = umur 15-30-45 hari setelah tanam. Hasil penelitian menunjukkan bahwa konsentrasi Atonik berpengaruh nyata terhadap berat basah dan berat kering bawang merah serta jumlah umbi bawang merah. ZPT Atonik dengan konsentrasi 0,50 cc/1 dapat meningkatkan produktivitas bawang merah. Interval penyemprotan Atonik tidak berpengaruh nyata terhadap berat basah umbi, jumlah umbi, diameter umbi, dan berat kering umbi bawang merah. Terdapat pengaruh interaksi antara perlakuan konsentrasi dan interval penyemprotan Atonik terhadap diameter umbi bawang merah. Atonik dengan konsentrasi 0,25 cc/l yang disemprotkan pada umur 15-20-25-30 hari setelah tanam dapat meningkatkan diameter umbi bawang merah. Kata kunci: Bawang Merah, ZPT Atonik. AbstractThis research was aims to determine how the the effect concentration and the interval of spraying intervals of Atonik PGR and interaction effect both of them on the productivity of shallots. The study was conducted in the of Arjasa, Kecamatan Arjasa, Jember on the elevation ± 141 meters above the sea level in July 2010 to October 2010. The research design used was Factorials RCBD with the 3 replication. The first factor was the concentration Atonik (K) consisted of 4 levels namely: K1 = 0.25 cc / liter, K2 = 0.50 cc / liter, K3 = 0.75 cc / liter, K4 = 1.00 cc / liter. The second factor that of spraying interval (I) composed of the 3 level namely I1 = age 15-20-25-30 days after planting, I2 = age 15-25-35-45 days after planting I3 = 15-30-45 days old planting. The results indicated that the concentrations of Atonik had significant effect on fresh weight, dried weight and also amount of bulbs shallots. Atonik PGR concentration of 0.50 cc / 1 could improve the productivity of shallots crop. The interval of spray of Atonik PGR did not significantly affect to bulbs fresh weight, number of tubers, bulbs diameter, and the dried weight of shallots bulbs. Treatment effect of interaction occurred among treatment of concentrations and the intervals of spray of Atonik PGR was against the shallots bulbs diameter. Concentration of Atonik PGR on 0.25 cc / l which be sprayed on the age of 15-20-25-30 days after planted could improve the diameter of the bulbs shallots. Keywords: Shallots, Atonik PGR.

Abstract

Abstrak: Produksi kopi di Desa Suci menghasilkan limbah yang banyak dan belum dimanfaatkan oleh petani maupun masyarakatnya. Limbah yang berasal dari pengolahan kopi tersebut banyak yang tertimbun dilingkungan rumah warga dan juga banyak yang dibuang ke sungai. Hal tersebut akan membahayakan kesehatan masyarakat apabila tidak dikelola dengan baik. Tujuan dari pengabdian ini adalah memberi pelatihan untuk meningkatkan pengetahuan dan keterampilan petani dan masyarakat di Desa Suci tentang pengelolaan limbah kopi menjadi produk yang bermanfaat yaitu media tanam sosis organik (kompos blok). Metode yang digunakan pada pengabdian ini dimulai dengan survei, kemudian melakukan sosialisasi kepada petani, kelompok wanita tani dan masyarakat. Langkah selanjutnya yang dilakukan adalah demonstrasi pembuatan media tanam sosis organik. Hasil dari kegiatan pengabdian adalah meningkatnya pengetahuan dan keterampilan petani, kelompoh wanita tani dan masyarakat di Desa Suci dalam mengolah limbah kopi menjadi media tanam organik dan memanfaatkannya pada kegiatan pertaniannya sendiri maupun memasarkannya langsung dan secara online. Berdasarkan kegiatan pengabdian yang telah dilaksanakan didapatkan pemahaman, pengetahuan dan keterampilan yang baik dari petani, ikatan wanita tani dan masyarakat tentang media tanam sosis organik.

Abstract

Agriculture in Indonesia faces major challenges in terms of sustainability and productivity, especially with the high dependence on chemical fertilizers that can damage the soil in the long run. This study aims to determine the impact of chemical fertilizer substitution with MOL organic fertilizer on rice productivity in Village X, East Java. This research used a quantitative approach with a comparative case study. Data were collected during one rice growing season from two treatment groups using different fertilizers. Primary data were obtained through field observation, direct measurement, and sample analysis, while secondary data were collected from village reports and previous studies. Data analysis was conducted using descriptive statistics and Structural Equation Modeling (SEM). The results showed that chemical fertilizer increased rice productivity higher in the short term than MOL organic fertilizer. Independent T-test results showed significant differences, with chemical fertilizers producing significantly higher yields (t-value 12.45, p-value 2.306). However, the use of chemical fertilizers negatively impacts soil quality and the environment in the long run. In contrast, MOL organic fertilizer improved soil quality despite lower yields. SEM analysis showed that the substitution of chemical fertilizer with MOL organic fertilizer had a significant effect but with a smaller estimated coefficient compared to the use of chemical fertilizer. MOL organic fertilizer provides long-term benefits by improving soil fertility so that to achieve high production and protect the environment, a combination of using chemical fertilizers at optimal doses and gradually using organic fertilizers is highly recommended to support sustainable agriculture.
