Abstract

Busuk pangkal bawang putih yang disebabkan Fusarium oxysporum Schlecht. f.sp. cepae (Hanz.) Snyd.et. Hans. adalah penyakit paling penting di Tawangmangu sejak musim tanam 2000. Penyakit ini telahmerugikan hasil bawang putih secara ekonomi. Penelitian ini bertujuan untuk menganalisis hubungan antarakondisi lingkungan tanah terhadap intensitas busuk pangkal bawang putih di Tawangmangu. Penelitiandilakukan melalui survei pertanaman bawang putih di daerah endemik busuk pangkal di Tawangmangu,Karanganyar, Jawa Tengah. Sebanyak 30 pertanaman bawang putih yang ditentukan dengan metode purposivesampling digunakan pada penelitian ini. Sampel tanah rhizosfer untuk keperluan analisis biologi dan kimia tanahditentukan dengan metode transect system. Data yang diperoleh dianalsis regresi linier berganda dengan programSPSS. Hasil penelitian menunjukkan bahwa intensitas busuk pangkal bawang putih di Tawangmanguberhubungan dengan perubahan kondisi lingkungan tanah. Intensitas busuk pangkal bawang putih cenderungtinggi pada lahan dengan kapasitas pertukaran kation, bahan organik, dan Nitrogen yang tinggi, tetapi Fosfor danKalium yang rendah.Kata Kunci: Fusarium oxysporum, busuk pangkal, bawang putih, ekologi. ABSTRACTBasal rot of gar;ic caused by Fusarium oxysporum Schleht. F.sp. cepae (Hanz.) Snyd et. Hans. Is the mostimportant disease in tawangmangu since planting season 2000. The disease has lased garlic productioneconomically. The aim of research was to analysze the relationship beetwen soil environmental condition towardintensity basal rot of garlic in Tawangmangu. Dat was collected by survey on garlic plant of epidemic area ofbasal rot in Tawangmangu, Karangayar, Central Java. There were 30 samples of garlic determined by purposivesampling method. Rhizosper soil sample for biological and soil chemical analysis gained by transect systemmethod. Data obtained where analyzed by multiple linear regression using SPSS softwere. The result showedthat intensity of garlic basal rot in Tawangmangu has significant relationship with the change of soilenvironmenr condition. Intensity of garlic basal rot terd to increase in lard which have high cation exchangecapacity, organic material and nitrogen, but low phosphorus and kalium.Keywords: Fusarium oxysporum, basal rot, garlic, ecology.

Abstract

Perlu adanya upaya implementasi kebijakan Merdeka Belajar-Kampus Merdeka (MBKM) padaperguruan tinggi. Tetapi beberapa perguruan tinggi yang tergolong muda masih memiliki keterbatasansumber daya. Berdasarkan hal tersebut, perlu adanya kerjasama dengan pihak ketiga. Metodepenelitian pengabdian ini meliputi analisis situasi, pelaksanaan kegiatan mulai dari persiapan sampaitahap kerjasama dan metode pelaksanaannya. Hasil yang dicapai dalam penelitian ini adalahterjadinya MoU kerjasama dengan pihak ketiga dalam rangka menyukseskan implementasi kebijakanMBKM di Universitas Muhammadiyah Purworejo. Hasil lainnya adalah terlaksana workshop danpertukaran pelajar sebagai implementasi kebijakan Merdeka Belajar-Kampus Merdeka (MBKM).

Abstract

This study aimed to identify the most effective combination of seed treatments and fungicide applications to control downy mildew on corn seeds. It also evaluated the efficacy of various fungicides in suppressing the spread of downy mildew. The research was conducted from October 2021 to January 2022 in Banggle Village, Kanigoro District, Blitar Regency, Central Java Province. The methodology employed a randomized complete block design, with treatment factors including seed treatment and fungicide spraying. Four treatment packages were utilized: one control group with no seed treatment or fungicide application and three others as comparators. Each treatment was replicated four times. The active ingredients used for seed treatment and field spraying included Dimethomorph, Pyraclostrobin, Oxathiapiprolin, and Fenamidone. The results indicated that downy mildew on corn emerged during the fourth week after planting. Corn treated with the fungicide packages exhibited significantly better outcomes compared to the control group. The most effective treatment package involved seed treatment with Dimethomorph and Pyraclostrobin, followed by spraying with Dimethomorph on the seventh day after planting, Oxathiapiprolin on the fourteenth day, and Dimethomorph once again on the twenty-first day after planting. This combination achieved the highest efficacy index of 70.67%.

Abstract

Garlic is a high-value commodity in Tawangmangu, one of its major production centers in Central Java. However, productivity in this region is seriously affected by Fusarium, the pathogen causes basal rot and wilting in the upper parts of the plant. The disease known as basal rot or Fusarium wilt, with the disease intensity in the field can exceeding  60%. Currently, chemical control remains the primary management strategies, which in organic farming, this practice is not acceptable. Therefore, environmentally friendly alternatives are required, such as using organic fertilizers, biological control agent like Trichoderma or combination. Trichoderma is also known as a cellulolytic microbe, which can enhance the composting process and produce Trichompost with improved quality. Field experiment results indicate that Trichocompost (TC) performs better compared to compost (C), Trichoderma (T), or untreated treatment. This findings suggest that garlic treated with Trichocompost and organic fertilizer show better growth with lower wilting intensity. Therefore, there is an indication that increased plant growth can reduce the intensity of Fusarium wilt in garlic.
