Abstract

Penyakit moler yang disebabkan oleh Fusarium oxysporum f.sp.cepae merupakan penyakit utama bawangmerah yang selalu ditemukan di setiap daerah penanaman dengan intensitas penyakit yang bervariasi. Variasi inididuga berkaitan dengan variasi virulensi patogennya dan variasi ketahanan varietas bawang merah. Beberapaisolat patogen diuji pada beberapa varietas bawang merah untuk mengetahui variasi virulensinya dan ketahananbawang merah terhadap penyakit moler. Lima varietas bawang merah yaitu Tiron, Filip, Kuning, Thailan, danBiru diinokulasi dengan empat isolat patogen yang berasal dari Kulonprogo (isolat Kp), Bantul (isolat Bt),Brebes (isolat Br), dan Nganjuk (isolat Ng). Sebelum inokulasi dengan cara perendaman umbi bibit dalamsuspensi mikrokonidium patogen konsentrasi 106, umbi didisinfeksi dengan perendaman dalam kloroks 1%selama 1 menit, dicuci dengan akuades steril, dan dikeringanginkan semalam. Umbi yang sudah diinokulasikemudian ditanam dalam polibeg yang berisi medium tanam yang berupa campuran tanah:pupuk kandang sapi2:1 v/v. Isolat Bt menunjukkan virulensi yang lebih tinggi dibandingkan dengan 4 isolat yang lain pada semuavarietas bawang merah yang diuji. Isolat Bt menyebabkan penyakit dengan intensitas yang lebih tinggi, danmenyebabkan kematian total pada varietas Kuning. Varietas Filip dan Biru adalah varietas yang paling tahan,sebaliknya varietas Kuning adalah yang paling rentan terhadap penyakit moler.Kata kunci: variasi virulensi, Fusarium oxysporum f.sp.cepae, resistensi, bawang merah ABSTRACTMoler (shallot twisting disease) caused by Fusarium oxysporum f.sp.cepae is a major disease on shallotthat is always found in every shallot plantation with various disease intensity. The variation of disease intensitymay be related to variation of virulence of the pathogen and the resistance of shallot varieties. Several isolatesof the pathogen were tested on several shallot varieties to know the variation of their virulence as well as theresistance of the shallot varieties. Five varieties of shallot i.e. Tiron, Filip, Kuning, Thailan, and Biru wereinoculated with four isolates of the pathogen originated from Kulonprogo (Kp isolate), Bantul (Bt isolate),Brebes (Br isolate), and Nganjuk (Ng isolate). Before inoculation by deeping the bulbs in 106/ml microkonidiumsuspension for 30 minutes, the bulbs were disinfected with 1% NaOCl for about 1 minute, washed with sterilizedaquadest, and air dryed overnight. The inoculated bulbs were then planted in polybags containing plantingmedium of soil:organic fertilizer 2:1 v/v. Bt isolate showed the higher virulence compared to 4 other isolates onall varieties tested. The isolate gave the higher disease intensity, and it caused total plant death on Kuningvariety. Filip and Biru varieties were the most resistant, whilst Kuning variety was the most susceptible to thedisease.Key word: variation of virulence, Fusarium oxysporum f. sp. cepae, resistance, shallot

Abstract

Massoi (Cryptocarya massoi (Oken) Kostem) is non-timber forest products of spices utillized for as food flavour, traditional medicine, and pharmacheutical material. This research is designed to describe the market chain, economic values, natural disturbance in local farming lands, natural regenarion, legal harvesting permit, and evaluate masohi bark quality to SNI 7941:2013, and determine an intervention for to increase the added values for local farmers. This research was undertaken in 13 villages at 6 subdistricts in Fakfak district West Papua. Interviews based on the questioner and field survey were conducted to collect the data. The results indicated that qualitatively local farming land for Masohi is 102,5 ha in total with for an average distance of 3.23 km form their homes. These farming land are scattered in both secondary and primary forest, cultivated with agroforestry system and planted insite ot in between Myristica trees. Regenerations are done using local nursery and natural sapling from the mother trees. Prices of the dried masohi bark have vary, at farmer IDR 50.000 – 60.000/kg, local collecter traders IDR 70.000/kg and legal harvesting permit holders for IDR 120.000/kg. An innovation for producing packaging masohi products with labels, standaritation and certification could provide significant impact on the added value for local farmers. The majoritas (53,85%) for legal harvesting permit is non-local communities. Local regulation is needed to gain the added values for masohi farmers. Masohi bark collected from Fakfak district could be utilized for raw material for Jamu and essential oil but properly drying is required to reduce the moisture content and elimate fungi contamination.

Abstract

Siam weed growing in any locations can be used for developing organic agriculture in Indonesia. The research was to find the quantitative and qualitative potential of siam weed as compost material for organic shallot cultivation. This study was descriptive-quantitative research using survey method done in four regencies in Yogyakarta Special Province and laboratory analysis. Purposive random sampling was used in survey method to determine the samples by applying random sampling and nested design. Laboratory analysis was to know nutrient content of siam weed. Shallot was planted using siam weed compost of 10 and 20 ton ha-1, inorganic fertilizer of 500 kg NPK Mutiara 16-16-16 ha-1 and the control. Siam weed was potential for developing organic shallot in Indonesia. Siam weed produced fresh biomass of 80 ton ha-1 with the population density of 24-37 individual m-2 and spread over almost all locations in Yogyakarta Special Province. Siam weed also contained higher nutrients of 2.56% N, 0.38% P, and 2.41% K with C/N ratio of 19.52 under the critical point of 30 so that easy to mineralized. The use of siam weed compost stimulated leaf number on shallot at 7 weeks after planting compared to the use of inorganic fertilizer and the control, but gave no significant yield of 19.71, 15.56, and 18.92 ton ha-1 of bulb, respectively.Keywords: organic fertilizer, development, nutrient

Abstract

The Urban Marital Satisfaction Scale (UMSS) was developed to measure marital satisfaction among couples living in urban areas by emphasizing financial and communication aspects that are often overlooked in previous instruments. This scale was constructed based on the theoretical framework of Spanier and Busby, which includes three key dimensions: dyadic consensus, dyadic cohesion, and dyadic satisfaction. A total of 52 initial items were developed and tested through readability trials, expert judgment, and item analysis. Based on empirical testing with married individuals aged 20 to 40 years, who had been married for at least two years, a total of 21 items were retained in the final version of the scale. The item selection process involved eliminating poorly performing items and revising ambiguous or culturally unfamiliar statements. Psychometric evaluations showed that the UMSS demonstrates strong internal consistency and good construct validity. The scale is also able to distinguish between individuals with high and low levels of marital satisfaction. These findings indicate that the UMSS is a reliable and valid measurement tool that can be used in psychological assessments and interventions targeting urban couples.

Abstract

Fusarium wilt caused by Fusarium oxysporum f. sp. lycopersici is a major disease that results in significant yield loss in tomato production. Currently, chemical control of Fusarium wilt using fungicides has yielded unsatisfactory results and has caused negative effects. Biological control using antagonistic microorganism combined with compost is a promising and environmentally friendly alternative management method for this disease. This research aimed to evaluate the effectiveness of an avirulent Fusarium oxysporum f. sp. cepae biological agent combined with siam weed compost to manage Fusarium wilt and increase growth and yield in tomato productions. This research was conducted using a completely randomized design with two factors and three replicates. The first factor was the dose of the avirulent F. oxysporum f. sp. cepae biological agent i.e 0 (control), 80, and 100 mL/plant. The second factor was dose of siam weed compost i.e. 0 (control), 300, and 600 g/plant. Disease intensity, plant growth and yield variables were evaluated. Data collected were analyzed using an ANOVA followed with Duncan’s Multiple Range test at 95% confidence level. The results showed that the use of avirulent F. oxysporum f. sp. cepae biological agent was able to manage Fusarium wilt disease in tomato productions and increase growth and yield of tomato. The best treatment for increasing tomato yield was the combination of 100 mL/plant of avirulent F. oxysporum f. sp. cepae with 600 g/plant of siam weed compost, resulting in a yield of 110.41 g/plant.
