Abstract

ABSTRACTSapodilla (Manilkara zapota (L.) van Royen) is a perishable fruit that exhibits rapid deterioration after harvesting. Low temperature storage has been extensively used to extend the storage life of many fresh commodities, however it is still rarely used for sapodilla. UV-C radiation has been studied for its capability to inhibit fruit ripening and senescence, and hence prolonging the period of fruit salability. This UV-C radiation might be a pre treatment for sapodilla before storage at low temperature. The objective of this research was to extend the storage life of sapodilla fruits by retarding ripening process through UV-C radiation and low temperature storage. Sapodilla fruits were exposed to four levels of UV-C exposure time i.e. 0 (no radiation), 5, 10, and 15 minutes, then stored at room temperature (27,13–28,11oC) and low temperature (16,70–18,13oC). Observations were taken on fruit respiration and ripening, and other related variables. The results showed that there was no interaction between UV-C radiation and storage temperature. The UV-C radiation did not significantly inhibit fruit ripening, thus did not inhibit the fruit senescence and deterioration. Keeping the fruit at low temperature inhibit fruit ripening and prolong its shelf life 6 days longer than those stored at room temperature. Key words : Sapodilla, UV-C radiation, low temperature storage, ripening, deterioration.

Abstract

ABSTRACTMerah Delimais considered as superior native variety of water apple in Demak. The fruitis wellknown as the high quality water apple  in theregions. Suitable environment of climate,topography and soil physic chemical properties in Demak make it possible for the fruit to produce more than twice per year with attractive physical appearance of the fruit as redand shiny color, large, sweet, crispy and high economic value. However, researches of Merah Delima water apple were still limited compared to other fruit superior commodities. Therefore, the survey as assessment method of water apple was conducted to identify and study the differences of cultivation, growth and production of the fruits which were cultivated in dryland and paddy fields as specific conditions of Demak regency. The assessmentseries included pre-survey in October 2011 – January 2012 and plant’s observation in March –June 2012 which was a peak season for the fruits. The site locations were chosen purposively ,i.e. in Wonosalam, Demak and Bonang Sub Districts. Inthatcase, water apple tree’s population differences were being the criteria of sites selection. Inpresurvey, as many as 50 farmers were interviewed as respondents with the proportion of consecutive 28 : 14 : and 8 farmers for each Sub District. The plant’s observation included 54 trees which were chosen purposively. ‘Nested design’ was used (3 subdistrict x 2 land types x 3 plants). Basically the cultivation results were compared to Water Apple Standard Operating Procedures (SOP) issued by Demak Agriculture Services. Parameters observed in the survey involved physical and chemical properties of soil, microclimate, growth, production and quality of water apple. The results showed that water apple cultivation applied statuses in dry and paddy field were only in low and medium, based on Water Apple Standard Operating Procedures (SOP). Infact, there were significant interaction effect between land types and cultivation applied as well as between the land types and cultivation applied in Merah Delima Water Apple production. Water Apple cultivation in surjan system or integrated with fish – farming system were less suitable since most of the time the roots were under anaerobic condition. Water apple cultivationis more suitable in flat land within termittent irrigation system since soil moisture was not relatively high. In Grumosol soi ltype, available soil moisture is considered as one of soil physical properties that has negative significant effect for Merah Delima water apple production, both in dry land and paddy field. In that case, the higher available soil moisture the lower water apple Merah Delima production.Key words: Merah Delima Water apple, cultivation, dry land, paddy field, Demak SubDistrict

Abstract

(Sesamum indicumL.) is one of important vegetableoil cropsin theworld. Indonesian local sesame cultivars in use today still have indeterminate growth types that cause simultaneous harvest, narrow adaptability and lower yield. Stage of the research is to see dynamics growth type of sesame due to environmental change and to find morphological and biochemical selection criteria of determinate growth cultivar. This study uses a factorial completely randomized design consisting of three replications. The first factor is six cultivars of sesame, two types of determinate growth type cultivar introduced from Turkey III Det 23, III Det 36 and four indeterminate growth type cultivars Sbr 3, Sbr 4, white local and black local. The second factor is six environments that combine various combinations of temperature and several concentrations of NaCl as salinity stress. The results showed that the environment combined heat stress temperature and salinity affect growth type of sesame. Heat stress makes longer vegetative phase and salinity stress causes black local genotype changed to determinate growth type. III det 23 and III det 36 were considered as stable determinate cultivar and best used as a parent crossing in sesame breeding program.

Abstract

INTISARILayu fusarium adalah penyakit utama melon yang disebabkan oleh Fusarium oxysporum f.sp. melonis (Fom). Pemuliaan tanaman secara in-vitro melalui variasi somaklonal telah digunakan selama beberapa dekade untuk  perbaikan karakter ketahanan tanaman.  Asam salisilat diketahui sebagai salah satu senyawa yang berperan penting terhadap ketahanan tanaman. Penelitian ini bertujuan untuk mendapatkan konsentrasi optimal dari asam fusarat yang dapat digunakan untuk tujuan skrining ketahanan layu fusarium secara in-vitro, mendapatkan tanaman tahan melalui seleksi in-vitro dan mengetahui hubungan kandungan asam salisilat dengan ketahanan tanaman melon terhadap layu fusarium. Kalus lima galur melon dipaparkan pada empat konsentrasi asam fusarat yaitu 0 ppm, 15 ppm, 30 ppm, dan 60 ppm. Hasil penelitian menunjukkan pertumbuhan kalus melon pada media dengan konsentrasi 0 dan 15 ppm tidak berbeda, penurunan pertumbuhan kalus mulai terlihat pada konsentrasi 30 ppm dan berlanjut pada konsentrasi 60 ppm. Galur paling tahan adalah galur M-21, sedangkan galur yang paling responsif saat regenerasi adalah galur M-13. Pertumbuhan kalus pada media seleksi dipengaruhi oleh genotipe masing-masing. Kalus yang mampu beregenerasi dan menghasilkan plantlet kemudian dinyatakan sebagai plantlet yang tahan pada tingkat in-vitro. Tanaman tahan memiliki kandungan asam salisilat alami (endogenous) lebih tinggi.Kata kunci: Fusarium oxysporum f.sp. melonis, Cucumis melo L., asam  fusarat, skrining  in- vitro, asam salisilat, ketahanan.

Abstract

Salinity stress is known for adverse effect on plants. Priming with salicylic acid was able to improve plant performance under salinity stress. This study aimed to determine the effect of priming duration with salicylic acid on growth, leaf anatomy and the optimal priming duration for sweet corn seedlings (Zea mays L.) under salinity stress. The experiment was based on Completely Randomized Design with two factors and five replications. The first factor was priming duration with salicylic acid (2 mM) with four different durations (0, 12, 18 and 24 h). The second factor was the level of salinity (NaCl 0% and 3%). Parameters observed were germination percentage, plant height, root length, fresh weight, dry weight, chlorophyll content, leaf proline content, leaf anatomy and stomatal density. Data were analyzed with t-test, ANOVA and followed by Duncan’s test at 95% confidence level. The results showed that 18-h priming duration observed as the highest germination percentage which was 7% higher than control.  Priming for 24 h showed phytotoxic effect for sweet corn on the germination phase by reducing the percentage of germination. The application of salicylic acid mitigated the toxic effects of NaCl stress on maize seedlings and considerably improved root and shoot growth, photosynthetic pigments, fresh weight, dry weight, proline content, and stomatal density, as well as could maintaining the leaf anatomy. The optimal priming duration with salicylic acid for sweet corn seedlings under 3 % salinity was 18 h.

Abstract

Dieng Volcanic Highland is one of the most intensive potato agricultural land in Indonesia, as well as frost disaster prone area. Frost indicated by appearance of frozen dew on the ground or vegetation surface due to cold temperatures during dry season. Frost causes damage to leaf tissue in potato plants, resulting crop failure and losses of up to tens of millions. Disaster management needs to be assess in order to achieve Disaster Risk Reduction (DRR) on agricultural land. This research aims to identify frost hazard areas based on local physical characteristics, analyze frost impacts on agricultural land, and provide preparedness recommendation to reduce the impact of frost disasters in Dieng Volcanic Highland. Research was conducted in Dieng Village, Wonosobo and Dieng Kulon Village, Banjarnegara. Method to assess hazard level was performed by spatial mapping technology using ArcGIS and comprehensive analysis using frost assessment through combinations of geomorphology, land use, proximity to water bodies and weather aspects. Dieng Volcanic Highland has a 125.59 hectare frost hazard areas, as many as 58.4 hectares of hazard areas are dominated by high level, while 24.84 hectares are moderate level and 42.95 hectares are low level. Cropland dominated by potato commodity has the highest hazard level, frost incident causing agricultural commodities to wither to death so that farmers experience losses. Frost losses in Dieng have a range from 800 thousand rupiah to over 155 million rupiah and only destructive on potato farm. In order to encourage agricultural resilience and reduce the loss of frost disasters, effort of preparedness can be done by passively and actively methods. Passive methods includes site selection, early warning system, shifting commodities, cropland modification, and appropriate calendar planting. Active methods includes frost modification using heaters, blower and sprinkle irrigation, and cropland covering using mulch, plastic or nets.
