Abstract

This study aims to 1). Observe and understand the stages of propagating F2 white oyster mushroom seedlings at Wairita Farm. 2). Compare the growth of F2 white oyster mushroom seedlings between corn cobs and a mixture of corn cobs and wood powder. 3). Improve the skills and add to the experience and knowledge of students so that they can apply the knowledge they have gained in the lecture hall. This study used a comparative descriptive experimental approach, which is to compare the growth of F2 white oyster mushroom (Pleurotus ostreatus) seedlings on two different types of seedling media. This research was conducted at the Wairita Farm in Wairbleler Village, Waigete District, Sikka Regency, East Nusa Tenggara Province, over a period of 7 days (Monday to Sunday) during working hours from 08:00 to 16:30 with a break from 11:30 to 14:00. This location was chosen because it is an agricultural business unit engaged in the cultivation of white oyster mushrooms (Pleurotus ostreatus). The study period was 3 months, from September 17 to November 17, 2025. Independent variables and dependent variables. Data were obtained through direct observation of mycelium growth, daily recording during the incubation period, and visual documentation. The results of this study indicate that the success of white oyster mushroom F2 seedling propagation is greatly influenced by the suitability of the medium to the physiological and ecological characteristics of the mushroom. A mixture of corn bran and wood powder proved to be more suitable and is recommended for use in the propagation of F2 white oyster mushroom seeds compared to pure corn bran media.

Abstract

This study aimed to compare the quality of Batu 55 tangerine (Citrus reticulata Blanco) fruit cultivated at PT. Kusuma Satria Dinasari Wisatajaya (Kusuma Agrowisata), Batu City, East Java, with the quality description of the national superior variety as stipulated in the Decree of the Minister of Agriculture No. 307/Kpts/SR.120/4/2006. The research was conducted for approximately four months, from September to November 2025, using a comparative research approach. Plant sampling was carried out using a systematic sampling method, involving 23 sample trees selected from a total population of 150 trees in Block A2. The observed variables included the number of fruits per tree, fruit diameter, fruit weight per fruit, and fruit sweetness level (% Brix). Compost fertilizer was applied at a dosage of 30 kg per tree as the cultivation treatment. The collected data were analyzed comparatively by contrasting field observation results with the official quality standards of the Batu 55 tangerine variety. The results indicated that compost application improved several physical quality attributes of Batu 55 tangerine fruit, particularly the number of fruits per tree, fruit diameter, and fruit weight, while the fruit sweetness level did not reach the standard value. Overall, the fruit quality generally met the characteristics of the superior variety, although variations were influenced by environmental conditions and cultivation practices. This study provides useful information for evaluating fruit quality and supporting sustainable cultivation of Batu 55 tangerines.

Abstract

Penelitian ini dilatarbelakangi oleh rendahnya produktivitas kakao di Indonesia, termasuk di Nusa Tenggara Timur, yang salah satunya disebabkan oleh penggunaan media pembibitan yang kurang sesuai dengan kebutuhan fisiologis tanaman. Penelitian ini bertujuan menganalisis karakteristik tekstur tanah serta pengaruh perbedaan tekstur media tanam, khususnya Inceptisol dan Ultisol, terhadap kualitas fisik media pembibitan kakao dan implikasinya bagi pertumbuhan awal bibit. Metode penelitian menggunakan pendekatan deskriptif-komparatif dengan teknik analisis laboratorium untuk mengevaluasi sifat fisik dan kimia tanah, termasuk pH, kandungan bahan organik, rasio C/N, dan tekstur tanah sebagai indikator kesesuaian media. Hasil penelitian menunjukkan bahwa Inceptisol memiliki tingkat kesuburan sedang, pH lebih mendekati netral, serta tekstur lempung liat berpasir yang lebih mendukung aerasi dan pertumbuhan akar, sedangkan Ultisol menunjukkan kesuburan rendah, pH lebih masam, dan tekstur lempung berpasir yang kurang stabil sebagai media pembibitan tanpa pembenahan tambahan. Temuan ini menegaskan bahwa perbedaan tekstur tanah berpengaruh signifikan terhadap kualitas media dan potensi pertumbuhan bibit. Kesimpulannya, Inceptisol lebih direkomendasikan sebagai media pembibitan kakao, sementara Ultisol memerlukan pembenahan bahan organik sebelum digunakan. Implikasi penelitian ini penting bagi pengembangan strategi perbenihan kakao pada berbagai kondisi lahan di daerah penghasil.

Abstract

The practical garden of the Faculty of Agriculture, Nusa Nipa University Maumere is a practical location for students of the Faculty of Agriculture intended for the cultivation of food crops and horticulture. The cultivation of these two types of crops at this location has been carried out intensively for several planting seasons without considering the land capability class of the land. Intensive agricultural activities on this land will continuously impact land capability, namely the degradation of land fertility, which will further affect the decrease in productivity. This research was conducted at the Practical Garden of the Faculty of Agriculture, Nusa Nipa University Maumere. The method used in this research is the survey method with data sampling using purposive sampling. Data processing was carried out using the arithmetic matching method, which involves matching the results of laboratory and field observations with the most dominant limiting factors in each sample. Based on the results of the land capability analysis using the arithmetic matching method, which is based on the most dominant land capability class from all observation parameters, the Faculty of Agriculture, Nusa Nipa University Maumere, as a whole has the same land capability class, namely Class I, with varying limiting factors, so the practical garden of the Faculty of Agriculture, Nusa Nipa University Maumere, is very suitable for agricultural cultivation activities.

Abstract

Research on the effect of liquid organic fertilizer dosage on the growth and production of mustard plants in polybags has been conducted in Nangameting Village, East Alok District, Sikika Regency. The purpose of this study was to determine the effect of liquid fertilizer dosage on the growth and production of mustard plants and to determine one of the appropriate liquid organic fertilizer dosages to increase the growth and production of mustard plants. This study used a Randomized Block Design (RAK) with five (5) treatments and (4) replications so that twenty (20) experimental units were obtained, namely: Oo (control/without fertilizer), O1 (300 ml/liquid fertilizer), O2 (600 ml/liquid fertilizer), O3 (900 ml/liquid fertilizer), O4 (1200 ml/liquid fertilizer). The results showed that the administration of liquid organic fertilizer on the height of mustard plants and the weight of fresh weight did not have a significant effect, but the placement of polybags in each group had a significant effect on the number of mustard plant leaves. The highest average base weight was found in the O3 treatment with a liquid fertilizer dose of 900 ml/polybag, namely 20.75 cm and the lowest average was in the Oo treatment without fertilizer with an average of 11.5 cm.

Abstract

This study aimed to determine the amount of revenue, costs, and income received by farmers in mung bean farming of the Fima 1 variety (certified) and the local Melo Palue variety (non-certified), as well as the level of profit and efficiency obtained from farming these two mung bean varieties in Magepanda Village, Magepanda District, Sikka Regency. The results showed that the lowest income of respondent farmers using the Fima 1 mung bean variety was IDR 4,088,000, while the highest was IDR 21,702,000, with an average income of IDR 8,650,690. Meanwhile, the lowest income of respondent farmers using the local Melo Palue mung bean variety was IDR 1,350,000, and the highest was IDR 9,484,000, with an average income of IDR 2,532,640. The efficiency of mung bean farming using the Fima 1 variety had an R/C Ratio value of 24, meaning that every expenditure of IDR 1 generated a revenue of IDR 24. In contrast, mung bean farming using the local Melo Palue variety had an R/C Ratio value of 9, meaning that every expenditure of IDR 1 generated a revenue of IDR 9. Therefore, mung bean farming using both varieties was considered efficient and feasible to cultivate. However, farmers are advised to use certified seeds, namely the Fima 1 mung bean variety, because it provides higher income and greater efficiency compared to the local Melo Palue variety.
