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 farmers' preferences for the characteristics of high-yielding rice varieties. The study was carried out from October 2022 – February 2023 in Kendawa Village, Jatibarang District, Brebes Regency. This type of descriptive study uses a survey method, namely collecting data from respondents with a questionnaire. How to determine the sample using proportional random sampling with the slovin formula, the selected sample is 39 respondents. The data analysis method used is the distribution of frequency tables. The results of the study showed that most respondents had a preference for high yielding rice varieties that were resistant to pests and diseases 97%, the appearance of clear white rice 92%, medium plant height 89%, the early maturity of the plant (105-125 DAP) 80%, the number of grains per panicle was 64% more. medium fertilization dose with high absorption 56%, unbalanced fertilization wind factor, water management and planted variety 56%, number of tillers per clump and number of seeds per planting hole, amount of fertilizer used 49% and rice flavor 41%. The distribution of superior varieties in Kendawa Village according to the first planting season of the Inpari 32 variety was 44%, 10% ciherang variety, 2% mekongga variety and 44% IR64 variety. Whereas in the growing season of the two Inpari 32 varieties it was 49%, mekongga 13%, situbagendit 8%, ciherang 5% and IR64 variety 25%.

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

Cabai rawit galur RCR 22 merupakan cabai jenis Capsicum frutescens. Benih galur RCR 22 mengalami penghambatan dalam perkecambahan sehingga perlu dikaji mengenai cara pematahan dormansinya. KNO3 berfungsi sebagai stimulan fisiologis yang membantu memecahkan dormansi benih, mempercepat imbibisi air, dan merangsang metabolisme dalam proses perkecambahan. Kajian dalam penelitian ini bertujuan untuk mempelajari efek perendaman KNO3 terhadap tingkat perkecambahan benih cabai RCR 22. Penelitian menggunakan Rancangan Acak Lengkap Faktorial dengan 2 faktor, yaitu konsentrasi KNO3 (0, 2,5 /l, 5 g/l, dan 7,5 g/l sebagai faktor pertama dan lama perendaman (1 detik, 30 menit dan 60 menit sebagai faktor kedua. Perlakuan dilakukan pengulangan sebanyak 3 kali. Data diuji menggunakan ANOVA pada taraf signifikansi 5%. Jika hasil menunjukkan pengaruh nyata, maka dilanjutkan dengan uji Duncan Multiple Range Test pada taraf 5%. Perlakuan KNO3 2,5 gr/l dan durasi perendaman 60 menit menunjukkan adanya interaksi nyata dan menunjukkan hasil terbaik dengan rerata tertinggi pada beberapa variabel, yaitu kecepatan tumbuh sebesar 3,33%, indeks vigor 34,00%, keserempakan tumbuh 46,44%, daya berkecambah 86,67%, tinggi tanaman 8,97 cm, dan panjang akar 7,87 cm
