Abstract

The problems associated with rice production in Indonesia appear very complicated, due to poor management of the sufficient national rice stock and various unfavorable public policies. Recently, government’s directives on rice importation instigated polemics from several interests, as a result of inappropriate decisions on general rice production, with possible yearly increment. Therefore, there is need to embrace strategy development to balance demand and supply. The purpose of this study was to analyze the rice supply chain in Demak and Sukoharjo, Central Java Province, in an effort to provide effective and collaborative distribution policies at individual levels. In addition, in-depth interviews were conducted for 98 respondents in a bid to acquire relevant and current information for the conceptual framework development. Furthermore, sampling methodologies, termed purposive and snowballing, were applied, followed by the preparation of interview guidelines. The results showed the farmers obtained the lowest revenue margin among other tiers, while several technical challenges were also identified. Consequently, the activities of middlemen with excessive dominant roles in market price determination, were overemphasized, leading to an inefficient supply chain. Meanwhile, government’s position through the Indonesia Logistics Bureau (BULOG) is assumed to be vulnerable in the control of direct supply from farmers or collectors. Based on this study, intense comprehension of rice supply chain was achieved, with further provision of collaborative strategies towards promoting the balance of demand and supply.

Abstract

Natural hydrocarbon compounds are extremely in high demand across various applications. For instance, squalene (SQ) is widely used in cosmetic and food supplement industries, due to beneficial health components. The aim of this study was to investigate the potentials of antioxidant addition on the physical properties, as well as SQ stability in spray-dried powder at various oil droplet diameters (0.3 – 4 µm). Rosemary oil extract served as antioxidant, while iron (II) sulfate accelerated the oxidation. Subsequently, SQ stability was evaluated at four separate temperatures, termed 25, 50, 70, and 105°C, after one month storage. Also, the morphological structures of the samples were characterized with scanning electron microscopy (SEM). The results showed the oil droplet diameter influenced the physical properties of SQ, as lesser drip sizes were known to enhance material strength. Furthermore, antioxidant inclusion proved to be effective in inhibiting oxidation, particularly in powders with extensive oil droplet diameter. Therefore, high regression coefficients (R2 > 0.97) and reduced chi-square confirmed Weibull model acceptance in predicting the retention of SQ content.

Abstract

In this study, a split plot experiment was conducted in a randomized complete blocks design with three iterations, for two years, in Gilan province (Iran), to investigate the impact of periodic irrigation and different planting distances on yield and yield components of rice plant. The irrigation was performed at five levels, I1, daily flooding irrigation (control treatment) and I2, I3, I4 and I5, every 5, 8, 10, and 15-days, respectively, as the main factor. Meanwhile, the planting distances were at four levels (S1: 20 × 20, S2: 25 × 25, S3: 15 × 30, and S4: 20 × 30 cm) as the sub factor. The simple effects of irrigation, as well as planting distance on all traits except harvest index, were significant at the level of 1%. In addition, the interaction of irrigation and planting distance on seed yield, plant height, number of seeds per panicle, biological yield, and water use were also significant at the level of 1%. The 20 × 20 planting distance resulted in the best conditions for the rice plant at different stress severities, thus, a 20 × 20 planting distance is appropriate in order to achieve good yield. Meanwhile, of the irrigation levels, 5-day irrigation led to the highest yield. The 5-day irrigation produced higher yield compared to flooding irrigation, and is therefore suitable for achieving higher yields as well as for water conservation, a major agricultural problem.

Abstract

The production, growth, and physiological processes of plants respond differently to the varying concentrations of nanoparticles. Due to the increasing importance and application of nanoparticles, it is essential to determine the impact on plants physiological systems. Therefore, this study investigated the effect of different bulk and nano nickel oxide concentrations on biomass production and the enzymatic system of fennel. The experiment was carried out in a completely randomized design with the applications of 5 replications and 5 concentrations (0, 20, 100, 400, and 800 ppm) in the greenhouse of the Faculty of Science, Mashhad Branch, Islamic Azad University. This study analyzed various plants traits, including shoot and dry root weight and a few antioxidant enzymes. The results showed that root and shoot dry weight were not affected by the applied treatments. Furthermore, all applied levels of treatment significantly increased the activity of fennel leaf polyphenol oxidase compared to the control. The bulk treatment at 800 ppm was exempted, where the application of bulk nickel oxide and nanoparticles decreased dehydrogenase enzyme activity. In addition, the activity of guaiacol peroxidase increased under all levels of treatments except 100 ppm nanoparticles. The highest amount of phenylalanine ammonia-lyase activity was obtained under 20 ppm treatment with a 61.98% increase compared to the control method. Furthermore, nickel oxide treatments also increased MDA. The results showed that nanomaterials' toxicity, caused oxidative stress in this plant, and the differences in MDA content of leaves explained the higher toxicity of NiO nanoparticles than bulk form. Moreover, higher activity of leaf antioxidative enzymes in bulk NiO2 treatments, especially Guaiacol Peroxidase, explained the plant's higher resistance to oxidative stress.

Abstract

Chao merupakan produk fermentasi tradisional dari daerah Sulawesi Selatan dengan bahan baku ikan tembang, garam dan nasi yang difermentasi dengan ragi tape dan ragi tempe. Penelitian ini menggunakan bakteri asam laktat  (BAL) proteolitik Lactobacillus plantarum Ags1-3 dan P. acidilactici Ags7-3 sebagai co-starter untuk mempelajari perananan dan potensinya sebagai penghasil ACE inhibitor selama fermentasi chao ikan tembang. Penelitian ini terdiri dari tiga tahap yaitu fermentasi garam (20%) (A-B), fermentasi BAL (C-D), dan fermentasi campuran BAL dengan nasi terfementasi (E-F). Sebagai kontrol adalah chao yang difermentasi tanpa penambahan inokulum BAL. Selama fermentasi diamati kadar garam, aktivitas air, populasi mikroorganisme, produksi asam dan perubahan pH serta kadar protein terlarut dan aktivitas inhibitor Angiotensin Converting Enzyme (ACE). Hasil penelitian menunjukkan bahwa pada fermentasi garam (A-B) terjadi kenaikan kadar garam pada ikan tembang dari 10,75% menjadi 16,48% dan tidak terjadi pertumbuhan mikroorganisme pada tahap ini. Pada tahap fermentasi BAL (C-D), terjadi kenaikan jumlah bakteri dan total BAL lebih dari 2 siklus log, namun pada kontrol, jumlah bakteri dan total BAL lebih rendah. BAL proteolitik mendegradasi protein menjadi komponen yang lebih sederhana yang ditandai dengan kenaikan yang nyata pada kadar protein terlarutnya dan tidak terjadi penurunan pH. Isolat BAL proteolitik berpotensi menghasilkan inhibitor ACE yang ditandai dengan aktivitas ACE-I mencapai 84-85%, sedang pada kontrol, aktivitas penghambatan ACE pada ikan yang difermentasi hanya 58%. Pada fermentasi campuran (E-F) terjadi peningkatan produksi asam dan penurunan pH yang nyata karena tersedianya sumber karbon yang berasal dari nasi terfermentasi. Fermentasi chao tanpa penambahan inokulum juga terjadi penurunan pH, namun nilai pHnya lebih tinggi. Fermentasi chao dengan penambahan inokulum BAL proteolitik berpotensi menghasilkan aktivitas penghambatan ACE dan dapat memperpendek waktu fermentasi.

Abstract

The application of bio-fertilizer (Glomus mosseae) and the selection of suitable cultivars are simple solutions to mitigate stress conditions such as water deficiency. This study was conducted in 2016 as a split-plot that was based on randomized complete block design with 3 replications. The effects of irrigation level, bio-fertilizer application and cultivar type on the reproductive efficiency and yield of corn were compared in the field experiment. Irrigation levels (after 70, 110 and 150 mm of pan evaporation) were placed as the main factor in the main plots. Application and non-application of bio-fertilizer (Glomus mosseae) as well as cultivar type (cultivars, 640 and 704) were placed in the subplots to study the physiological differences, reproductive efficiency, and yield of corn. This study showed that the cultivars performed differently in their response to water deficiency. The highest grain yield for 704 cultivars was obtained when we applied irrigation after 70 mm evaporation from pan. When subjected to the treatment of irrigation after 110 and 150 mm evaporation from pan, lower grain yield per unit area of 19% and 50.6%, respectively was recorded. The 640 cultivars produced less yield under full irrigation than 704 cultivars. Water deficiency had no beneficial effects on grain yield per unit area (P > 0.01). It was also observed that bio-fertilizer treatment increased the corn yield by 25.2 %. Water deficiency, bio-fertilizer and cultivar type affected the grain yield as differences were observed in the main components of kernel row number and 100-kernel weight. Water deficiency had no beneficial effects on ‘chlorophyll a’ content, but decreased the content of chlorophyll b. Water deficiency and bio-fertilizer application caused an increase in the catalase and peroxidase content. The best plant per­formance was observed in plants grown under complete bio-fertilizer (704 cultivar) and at after 70 mm irrigation level. Bio-fertilizers can be used in order to improve corn production and also as environmentally friendly fertilizers under deficit irrigation regimes.

Abstract

Green manure as a source of soil organic matter is an important indicator of potential agricultural ecosystems capable of preventing erosion, reducing runoff, increasing soil permeability, improving ventilation, ameliorating the temperature, and enhancing the function of microorganisms. Therefore, to investigate the effects of green manure Sulla (Hedysarum coronarium) and nitrogen fertilizer on maize yield in Kermanshah, an experiment was carried out as split-plot in a randomized complete block design with 3 replications. The main factor was the use of Sula in two levels, namely application and non-application, while, the sub-factor was the application of N fertilizer at four levels of zero, 200, 400 and 500 kg/ha. The highest leaf area index was observed by 400 kg/ha N application along with green manure. Grains per ear determined using green manure and nitrogen fertilizer at levels of 0, 200, 400 and 500 kg/ha increased by 8, 10, 15, and 15%, respectively. The result showed that the Sulla green manure treatment increased the grain yield by 10% compared to the control treatment. Furthermore, the highest grain yield was obtained under two treatments of 400 and 500 kg N/ha which was significantly different from other levels of N applications. The application of green manure application also increased the maize protein content by 8% with a rise in the highest levels of nitrogen fertilizer. Meanwhile, the application of Sulla as a green fertilizer or pre-planting had a positive impact on increasing soil organic matter and maize yield. Therefore, cultivation of Sulla can be considered a positive task towards sustainable agriculture.
