Abstract

The Ralstonia solanacearum species complex is a highly destructive plant pathogen with a remarkably broad range of hosts, and ongoing discoveries continue to expand its host list. In May 2023, a new type of bacterial wilt affecting ginger (Z. officinale) crops in Semarang Regency, Central Java was reported. Early symptoms included sudden withering of leaves in adult plants followed by complete wilting and darkening of the vasculature, ultimately leading to plant death. This research specifically investigates the spread of Ralstonia solanacearum Species Complex within ginger cultivation in Semarang Regency. Twenty bacterial isolates were collected from soil and diseased Z. officinale plants at twenty different locations. Physiological and biochemical analyses confirmed that the causative agent for Z. officinale bacterial wilt was Ralstonia solanacearum belonging to biovar 3 and 4. The study also revealed that the distribution of this pathogen remains focused in the Banyubiru and Sumowono sub-districts. These findings will enhance our understanding of how Ralstonia solanacearum Species Complex spreads among ginger crops and its impact on them.

Abstract

Garlic has a bitter taste, which makes people reluctant to eat one whole garlic clove. The salt soaking technique used to reduce the bitter taste of the garlic, and the garlic processed into wet candied garlic, so it became more edible than not process. The process of candied garlic could preserve the durability level, which allows it to be stored longer at low temperatures. The research materials used were salt and sugar. The purpose of the research was to know the effect of salt concentration on reducing bitterness and the right concentration to reduce the bitter taste of garlic. This research used the RAK method, and DMRT (Duncan’s Multiple Range Test), and the samples of salt were 3%; 3.5%; 4%; 4.5%. The test included chemical tests (water content and total microbes) and organoleptic tests (taste, aroma, and texture). The water content of the product showed the result, which was not significantly different, and the total microbes test showed no microorganism was found or grew on the product. The organoleptic test of taste was obtained on 3.5% salt, with an average of 2.75% (likes), while the aroma and texture did not show a significant difference in the result. The aroma and texture data obtained on 2.90 (likes) and 2.40 (likes) with 3.5% salt. Keywords: Candied; Garlic; Salt; Soaking; Sugar.

Abstract

Food safety is the condition and effort needed to prevent food from three possible contaminations, namely: biological, chemical and other contamination that can disturb, harm and endanger human health. Sumberejo Village is a Partner of Faculty of Agriculture and Business, Universitas Kristen Satya Wacana. Sumberejo Village has potential resources in the form of vegetables. It is supported by climate and temperature conditions that are suitable for vegetable production. One of the superior commodities produced in Sumberejo Village is beetroot fruit. Processing agricultural products into processed food products is an effort to increase economic value when prices fall or during harvest time. Processing beet tubers into processed products such as cookies, beetroot tea bags, cakes are one way to reduce losses due to falling prices and increase the selling value of beet tubers. Knowledge and safe food processing practices are very necessary in food processing activities. Through food safety education activities, it is hoped that the women farming community in Sumberejo village will be able to process beet tubers in accordance with the concept of food safety. The aim of this Community Service activity is to provide knowledge and understanding of female farmers in Sumberejo Village regarding food safety and efforts to prevent contamination during food processing and producing food that is safe for consumption by the community. Based on the results of implementing safety education activities in Sumberejo Village, it can be concluded that there has been an increase in knowledge about food safety. It can be seen in the results of the questionnaire that knowledge about food safety is important because it concerns health

Abstract

This study aimed to analyze the effect of applying liquid organic fertilizer (POC) derived from a combination of three materials on the growth and yield of radish plants (Raphanus sativus L.). The research utilized a randomized block design (RBD) with five treatment doses, namely TBT0 (control), TBT100 (100 ml/plant), TBT200 (200 ml/plant), TBT300 (300 ml/plant), and TBT400 (400 ml/plant). The results showed that applying POC at a dose of 200 ml/plant (TBT200) produced the highest average number of leaves (29.90 leaves) and the highest radish bulb weight (483.62 grams). However, the application of POC to leaf area, chlorophyll content, and dry leaf weight exhibited a pattern without significant changes among the treatments. Soil nutrient content also decreased as it was utilized by the plants during growth. In conclusion, the application of POC doses made from liquid tofu waste, kipahit (Tithonia diversifolia), and banana stems significantly influenced the number of leaves, fresh leaf weight, and productivity of radish plants. However, POC application did not significantly affect leaf area, chlorophyll content, or dry leaf weight. Keywords: Banana Stem, Kipahit (Tithonia diversifolia), Liquid Tofu Waste, POC, Radish Plants

Abstract

Penyakit busuk pelepah merupakan salah satu penyakit penting pada tanaman padi yang dilaporkan semakin meluas dan berdampak signifikan terhadap penurunan hasil. Selain Sarocladium oryzae, beberapa spesies Fusarium, termasuk Fusarium longipes, diketahui berasosiasi dengan penyakit ini dan berpotensi memperparah kerusakan tanaman. Penelitian ini bertujuan untuk mengevaluasi tingkat ketahanan beberapa varietas padi terhadap penyakit busuk pelepah akibat infeksi F. longipes berdasarkan keparahan penyakit dan parameter epidemiologi. Penelitian dilaksanakan di rumah kaca menggunakan sepuluh varietas padi, yaitu Ciherang, Sunggal, Inpari 32, Inpari 42, Inpari 43, Memberamo, Situ Bagendit, IR64, Padjadjaran, dan SRP08, yang disusun dalam rancangan acak kelompok dengan tiga ulangan. Inokulasi dilakukan pada umur 60 hari setelah tanam menggunakan bulir beras yang telah dikoloni F. longipes. Pengamatan keparahan penyakit dilakukan pada 3, 6, 9, 12, dan 15 hari setelah inokulasi. Hasil penelitian menunjukkan bahwa keparahan penyakit meningkat seiring waktu pengamatan dan berbeda antarvarietas. Pada akhir pengamatan, seluruh varietas menunjukkan keparahan penyakit yang tinggi dan diklasifikasikan sebagai sangat rentan berdasarkan kriteria IRRI. Nilai laju infeksi dan Area Under Disease Progress Curve (AUDPC) menunjukkan adanya perbedaan dinamika perkembangan penyakit antarvarietas, meskipun tidak ditemukan varietas dengan tingkat ketahanan efektif terhadap infeksi F. longipes. Hasil penelitian ini menegaskan pentingnya evaluasi ketahanan varietas sebagai dasar pengelolaan penyakit busuk pelepah dan pengembangan varietas padi yang lebih adaptif.

Abstract

Curly chili (Capsicum annum L.) is one of the vegetable commodities widely cultivated in Indonesia which has a high selling value. Although it has a high selling value, chili cultivation has many obstacles, one of which is the attack of pathogens that reduce the yield of curly chili, especially yellow curly leaf disease on agricultural land. Yellow curly leaf disease is always found in chili cultivation and is the main production obstacle in Indonesia that reduces the harvest. This study aims to see the impact of yellow curly disease attacks in the vegetative and generative phases on the growth and yield of curly red chili cultivation. The study was conducted from August 2023 to March 2024 using the field observation method from the beginning of growth to harvest. Observations were made by measuring the parameters of plant height, stem diameter, number of branches, number of productive branches, fallen flowers, fruit weight, fruit length and observation of yellow curly disease pathogens. The results of the study showed that attacks of yellow curly disease in the vegetative and generative phases had a significant effect on the growth parameters and yield of curly red chili plants. From the results of the analysis of yellow curly disease attacks in the vegetative phase, the number of fruits and fruit weight were lower, namely 10.90 and 32.04 grams/tree, compared to attacks in the generative phase which produced 24.27 and 77.67 grams/tree. Keywords: Begomovirus, Generative, Vegetative, Whitefly, Yellow curl.

Abstract

Vanda tricolor orchid is propagated by in vitro culture using Vacin & Went (VW) media. The price of this media is quite high, so research is needed on alternative media that can replace VW media. The objectives of this study were to (1) determine the effect of foliar fertilizer concentration and addition of organic materials on in vitro protocorm regeneration in to planlets, (2) obtain a combination of foliar fertilizer concentration and organic materials that can be used to subtitude VW as a medium for Vanda tricolor protocorm regeneration. The treatments tested were the concentration of NPK foliar fertilizer (21:21:21), namely:     1 g/L, 1.5 g/L, 2 g/L, and 2.5 g/L and various organic materials, namely: no organic material, banana, potato, banana+potato. VW was use as a control. Data analysis to compare VW control with all treatments used Orthogonal Contrast further test, while to compare between treatment combinations using Analysis of Variance (ANOVA) and DMRT further test at the 5% level. The results showed that leaf fertilizer at a concentration of 2.5 g/L was able to accelerate the formation of shoots and roots without the addition of organic material. In addition, leaf fertilizer media plus potatoes can be used to replace VW as a protocorm regeneration media at affordable cost.
