Abstract

ABSTRAKTanah regosol umumnya memiliki kesuburan tanah rendah. Upaya perbaikan kesuburan tanah dapat dilakukan menggunakan pembenah tanah Tujuan penelitian untuk mengetahui pengaruh pembenah tanah terhadap biomasa bawang merah. Penelitian dilaksanakan di Kapanewon Kalasan, Kabupaten Sleman, Provinsi D.I. Yogyakarta pada Juni-Juli 2023. Rancangan penelitian menggunakan rancangan acak kelompok (RAK) diulang 3 kali. Bahan pembenah tanah dalam perlakuan ini terdiri dari H0:tanpa pembenah (kontrol); H1: pupuk kandang sapi 10 ton/ha; H2: arang sekam 5 ton/ha; H3: asam humat 3 kg/ha; H4: pupuk kandang sapi 5 ton/ha dan arang sekam 2.5 ton/ha; H5: pupuk kandang sapi 5 ton/ha dan asam humat 1.5 kg/ha; H6: asam humat takaran 1.5 kg/ha dan arang sekam 2.5 ton/ha dan H7: pupuk kandang sapi takaran 3.3 ton/ha; asam humat 1 kg/ha dan arang sekam 1.6 ton/ha. Hasil penelitian menunjukkan bahwa Bahan pembenah tanah tidak berpengaruh nyata terhadap jumlah daun, klorofil daun, kadar air relatif (KAR) daun, biomasa/rumpun (berat brangkasan segar dan kering jemur, umbi segar dan kering jemur; daun segar dan kering), berat/umbi dan jumlah anakan, namun berpengaruh nyata pada diameter umbi dan tinggi tanaman 3 dan 5 MST. Perlakuan H4 memberikan diameter umbi yang paling besar dibanding perlakuan yang lain, yaitu sebesar 28.16 mm.  ABSTRACTRegosol generally has low soil fertility. Efforts to improve soil fertility can be carried out using soil amendments. The aim of the research is to determine the effect of soil amendments on shallot biomass. The research was conducted in Kapanewon Kalasan, Sleman Regency, D.I. Province. Yogyakarta in June-July 2023. The research design used a randomized block design (RAK) repeated 3 times. The soil amendment materials in this treatment consisted of H0: no amendment (control); H1: cow manure 10 tons/ha; H2: husk charcoal 5 tons/ha; H3: humic acid 3 kg/ha; H4: cow manure 5 tonnes/ha and husk charcoal 2.5 tonnes/ha; H5: cow manure 5 tons/ha and humic acid 1.5 kg/ha; H6: humic acid at a rate of 1.5 kg/ha and husk charcoal at a rate of 2.5 tonnes/ha and H7: cow manure at a rate of 3.3 tonnes/ha; humic acid 1 kg/ha and husk charcoal 1.6 tons/ha. The results showed that soil amendments had no significant effect on the number of leaves, leaf chlorophyll, relative water content (KAR) of leaves, biomass/clump (weight of fresh and sun-dried stover, fresh and sun-dried tubers; fresh and dry leaves), weight/ tubers and number of tillers, but had a significant effect on tuber diameter and plant height at 3 and 5 WAP. The H4 treatment provided the largest tuber diameter compared to the other treatments, namely 28.16 mm.

Abstract

This study aims to determine the increase in rice production with sub-optimal land use in the Makmur I Farmer Group in Banjaranyar Village. The research method used is survey. The sampling technique was purposive sampling, with a total sample of 30 respondents belonging to the Makmur I Farmer Group. Data analysis used descriptive analysis using a Likert scale tool. The results showed that there was an increase in rice production on sub optimal land. Increased rice production in sub-optimal land occurs due to the application of technology, namely tillage with tractors, pumping irrigation technology, use of superior and early maturing varieties, use of balanced fertilizers with organic fertilizers, and adjusting cropping patterns

Abstract

This study aims to determine the prospects for the use of organic fertilizers in the cultivation of shallot bulb seeds in the Sumber Pangan farmer group, Butterfly Village, Wanasari District, Brebes Regency. The research method used is a survey with a questionnaire. The sampling technique used was the population sampling technique, namely from the entire population of 48 respondents taken by census. Data analysis used descriptive analysis using a Likert scale tool. The results showed that the prospects for using organic fertilizers were classified as good with the parameters measured being in the medium category, as evidenced by the results of the parameters measured starting from the achievement of the level of development in the high category, the ease of obtaining organic fertilizers and organic raw materials in the high category. Understanding of the function and dosage of organic fertilizers in the moderate category. Achievement of the level of use of organic fertilizers, in the medium category, achievement of the use of liquid organic fertilizers, all in the medium category. The use of solid organic fertilizers in the low category. The application of organic fertilizers is still in the low category. From the results of this study, the empowerment strategy for the Sumber Pangan farmer group is counseling with material on the manufacture and use of organic fertilizers. The development strategy is by increasing counseling to increase farmers' knowledge of attitudes and skills (PSK) regarding organic fertilizers, and attempted with demonstration plots on the use of organic fertilizers.

Abstract

Salah satu tanaman hortikultura yang populer di Indonesia adalah sawi hijau. Tanaman ini mempunyai nilai ekonomi yang tinggi setelah tanaman lainnya seperti kubis, kol, dan brokoli, sehingga sayuran jenis ini mempunyai prospek pengembangan yang potensial di bidang pertanian. Penelitian ini bertujuan untuk mengetahui karakter agronomi dan morfologi beberapa varietas tanaman sawi hijau. Penelitian ini dilaksanakan pada bulan Februari – Maret 2025 di lahan CV. Triasputra Agro Maju Sejahtera yang terletak di Kecamatan Ngluwar, Kabupaten Magelang, Jawa Tengah pada ketinggian tempat 202 mdpl dan suhu rata-rata 22-32ºC. Penelitian menggunakan Rancangan Acak Kelompok Lengkap (RAKL) dengan 4 perlakuan varietas dan 4 ulangan. Perlakuan varietas terdiri dari A: Varietas PSA, B: Varietas Tossan, C: Varietas Juwita 01, dan D: Varietas Kometa. Parameter pengamatan terdiri dari karakter agronomi umur panen, tinggi tanaman, panjang daun, panjang tangkai, lebar daun, jumlah daun, produktivitas dan daya simpan. Karakter morfologi terdiri dari bentuk daun terluar, warna daun terluar, bentuk biji, warna biji. Data karakter agronomi dianalisis dengan uji F apabila terdapat beda nyata maka pengujian dilanjutkan dengan Uji BNJ 5% menggunakan software PKBT-STAT versi 3.2. Karakter morfologi dianalisis deskriptif dengan berpedoman pada Panduan Pelaksana Uji (PPU) dan International Union for the Protection of New Varieties of Plants (UPOV). Hasil penelitian menunjukkan bahwa secara agronomi, perlakuan varietas nyata berpengaruh terhadap parameter tinggi tanaman, panjang daun, panjang tangkai, lebar daun, jumlah daun, dan produktivitas. Secara morfologi menunjukkan Varietas PSA mempunyai perbedaan pada parameter warna daun dan bentuk daun terluar dari varietas lainnya.

Abstract

In general, infrastructure development requires materials from nature and one of them is natural coarse aggregate of crushed stone. The rapid development of infrastructure in Indonesia has resulted in the depletion of the natural coarse aggregate. Therefore, other efforts are needed in terms of using coarse aggregate as a construction material. So in this study the aim is to make artificial coarse aggregate made from fly ash. The results showed that this artificial coarse aggregate met the requirements of the General Specifications of Bina Marga 2010 rev 3 as a construction material, namely for an abrasion value of 40% and water absorption of 3%. In this study, 5 types of comparisons were carried out, namely, 70:30%, 60:40%, 50:50%, 40:60%, 30:70 and for the type of composition comparison 70:30% (70% fly ash:30% cement). ) the abrasion value is still below 40%, and the amount of water absorption is below 3% so that this artificial coarse aggregate still meets the standard specifications of General Highways 2010 rev 3. Based on the price comparison that has been made between artificial coarse aggregate and natural coarse aggregate of crushed stone , shows a price disparity of Rp. 35,779 - Rp. 58,779. Thus, this artificial coarse aggregate is one solution that can be developed to reduce the environmental impact due to the presence of fly ash which is quite abundant in Indonesia.
