Abstract

Tiyung cultivar, the consumer preferences of hot pepper in Magelang Regency, is still low in productivity (7 ton.ha-1). This research aimed to determine the growth and yield of hot pepper planted in relay intercropping as affected by biological agent application as a technology to increase productivity. This research was arranged in a Factorial Randomized Complete Block Design with an intercropping pattern of hot pepper (two and three rows model). The second factor was the application of biological agents, consisting of Trichoderma asperellum, Bacillus velezensis B-27 and Arbuscular Mycorrhizal Fungi (with and without biological agents). The control was the monoculture of hot pepper without biological agent application. The data observed were analyzed using Analysis of Variance and followed by the Duncan's Multiple Range Test at α= 5 %. The results showed that the relay intercropping of hot pepper produced less numbers of branches and leaves.  It indicated more efficiency in the use of assimilates for the development of generative organs, thereby resulting in the high values fruits weight per plant, which were as high as those in monoculture. The productivity observed in relay intercropping was 12.93 ton.ha-1, which was 15.8 % higher than in monoculture. The application of biological agents significantly increased the stomatal density, the size of stomatal opening, the number of leaves, weight of fruits per plant and productivity of hot pepper. The productivity of plant applied with biological agents was 16.84 ton.ha-1, which was 86.50 % higher than that without biological agents application.

Abstract

Sandy coastal area is a poor land, with minimal nutrients and low ability to store water and nutrition. Therefore, plant is difficult to grow well, consequently the treatments for improving sandy coastal is required before planting to support their growth. Application of Trichoderma as a plant-growth promoting and controlling pathogens had been known. Shallot seed treatment by Trichoderma agents was intended to improve and support plant growth and yield in the sandy coastal land. The aim of experiment was to determine the most effective treatment to improve growth and yield of shallot on sandy coastal land. The experiment had been carried out in Yogyakarta during August - November 2015. The factorial treatments of cultivar and Trichoderma applications were arranged in Completely Randomized Design with three replications. The shallot cultivars consisted of Tiron, Crok, and Biru, while Trichoderma application consisted of control (no treatment), sprayed with Trichoderma, soaked in Trichoderma, matricontioning media i.e. rice husk charcoal and brick in combination with Trichoderma. The collected data related to plant growth and yield. The result showed that seed treatment methods with Trichoderma increased the plant height, the leaf area index, extensive root, net assimilation rate (NAR), plant growth rate (PGR), Nitrate Reductase Activities (NRA), total chlorophyll, and fresh bulb weight. The best technical treatment for cultivar Tiron was soaked with Trichoderma, and Crok was sprayed with Trichoderma, while Biru cultivar was using brick in combination with Trichoderma.

Abstract

Fusarium wilt caused by Fusarium oxysporum f.sp.cepae (Foc) is one of the most important diseases of onion in Indonesia. Induced resistance was one of the effective techniques to acquire resistance to fusarium wilt in shallot. Salicylic acid (SA) had been inferred to be in endogenous signal in the systemic acquired resistance response of plants. This research aimed to study the effect of exogenously added SA to resistance in shallot callus cv ‘Bima Brebes’ to fusarium wilt disease in vitro; and to determine the effective concentration of SA to induce resistance. A group of shallot callus was grown in MS medium containing varying SA concentration (0, 15, 20 and 25 ppm) in vitro for 2 weeks. Then, the callus were treated with toxin of Fusarium oxysporum, namely fusaric acid, to have observe the resistance response. In vitro selection was done twice in different fusaric acid concentration. Application of exogenous SA at all concentration did not suppres time of appearance of disease symptom yet. Toxic symptom in the callus was shown by the browning or blackening (off) of callus. Salicylic acid at concentration of 20 ppm effectively reduced the toxic symptom up to 16.66% and supported callus regeneration better than the concentration of 15 ppm and 25 ppm. The number of resistant callus regenerated was 66.67% at pretreatment of 20 ppm of SA.

Abstract

The marginal sandy coastal land should be utilized to maintain production level of shallot. But for increasing the productivity of sandy coastal land, in the shallot cultivation should be applied biological fertilizers, such as Plant Growth Promoting Rhizobacteria (PGPR). The purpose of this research was to obtain the most effective isolate of PGPR (Plant Growth Promoting Rhizobacteria) to the growth of three shallot cultivars in the sandy coastal land. The research had been conducted in August-November 2015 at Samas sandy coastal land, Bantul. The Factorial treatments were assigned in Randomized Complete Block Design with three blocks as replications. The first factor was shallot cultivars consisted of Crok, Tiron and Tuk-tuk, while the second factor was the PGPR suspension, i.e. control (without PGPR), PGPR isolates BP25.2 (Bacillus methylotrophicus), BP25.6 (Bacillus amyloliquofaciens), BP25.7 (Bacillus subtilis), BrSM 4 (Burkholderiacepacia), and BrSG 5 (Burkholderiaseminalis). The data of growth and yield were analyzed using ANOVA with α = 5%, then followed by DMRT α 5% . The result showed that Tiron cultivar was able to grow in sandy coastal land, proven from its good germination, high number of bulb, high fresh weight, and dry weight of bulb. Meanwhile, BP25.2 isolate was able to increase seed growth simultaneously of Tiron cultivar and BrSM 4 isolate was able to increase the chlorophyll content of Tuk-tuk cultivars.

Abstract

Shallot (Allium cepa L. Aggregatum group) is one of the most widely utilized vegetables by Indonesian people. Some technologies have been adapted to improved shallot productivity. One of those are the application of beneficial microorganisms. We applied mycorrhizal fungi, Trichoderma sp., and Bacillus thuringiensis as well as the combination among these microorganisms were applied in Shallots cultivation and were investigated to improve the growth and development of shallot. A field experiment was arranged in a Randomized Complete Block Design with two treatment factors. The first factor consisted of two shallot cultivars, namely Biru Lancor and Crok Kuning; whilst the second factor consisted of six beneficial microorganism treatments, i.e. control, mycorrhizae, Trichoderma sp., Bacillus thuringiensis, the combination of mycorrhizae and Trichoderma sp., and the combination of those three microorganisms. The observation was conducted on infection percentage of mycorrhizae, total population of Trichoderma sp., leaf area, leaf area index, net assimilation rate, crop growth rate, harvest index, and plant yield. The data obtained were subjected to analysis of variance (ANOVA) and continued with Duncan’s Multiple Range Test (DMRT) at 5% significance level. The results showed the leaf area of shallot was improved as affected by the application of mycorrhizal fungi. The effectiveness and implication of mycorrhizal fungi on shallot growth would decrease if the application of was combined with other microorganisms. However, the application of beneficial microorganisms had not been able to increase component yield and yield of Biru Lancor and Crok Kuning, indicated by bulb weight, number of bulb, bulb diameter, number of bulb per cluster, and bulb yield per hectare.

Abstract

Tinfoil barb Barbonymus schwanenfeldii is recognized as one of the potential aquaculture commodities in Indonesia. Nonetheless, lack of data on their environmental tolerance causing this issue to become essential to be investigated. The present study was carried out to assess the pH influence on growth and physiological response of juvenile tinfoil barb. Juvenile tinfoil barbs (TL: 5.5 ± 0.8 cm; BW: 2.4 ± 1.0 g) were treated with four pH level treatments (5, 6, 7, and 8) and three replications with the stocking density of 10 fish each aquarium. Fish were kept for 21 days and fed with commercial fish feed. In this study, pH 8 exposure resulted to lower growth of juvenile tinfoil barb compared to pH treatment 5 to 7 (p<0.05). In terms of survival rate, the results show significantly lower value at pH 8 treatment compared to those of pH 6 and 7 treatment (p<0.05), while it is not significantly different with pH 5 treatment (p>0.05). Additionally, this study found the highest value of glucose, cortisol, and aspartate aminotransferase (AST) on pH 8 treatment (p<0.05). On the other hand, pH 8 exposure led to the lowest creatinine, blood urea nitrogen (BUN), and ALP level (p<0.05). In conclusion, the optimal pH for juvenile tinfoil barb rearing ranged around 6-7.

Abstract

Hypoxia is one of the critical issues in aquaculture production systems as it can lead to physiological disturbances in cultured fish. This research aimed to evaluate the tolerance level and physiological responses of domesticated Asian redtail catfish Hemibagrus nemurus reared in various hypoxia conditions. A total of 12 fish/treatment were acclimated to gradually decreased dissolved oxygen treatments until fish experienced aquatic surface respiratory (ASR) and loss of equilibrium (LOE). Cortisol, haemoglobin, and glucose levels were detected in the blood plasma to evaluate the stress response of the fish to hypoxia. The result showed that ASR of H. nemurus was identified at 2.17 ± 0.14 ppm of dissolved oxygen (DO) concentration with the percentage of ASR was 77.67 ± 9.53%, while LOE critical of H. nemurus happened at 0.63 ± 0.15 ppm of DO where 55.56 ± 4.81% of the fish experienced LOE. There were significant differences in the values of physiological parameters (blood cortisol, haemoglobin, and glucose) between control and treatments as fish experienced LOE (P<0.05). In the present  study, it was found that the Asian redtail catfish is classified as a hypoxia-sensitive fish group. Tehis finding is valuable information for the rearing and growing of the fish to provide an optimal DO concentration for their growth and survival.

Abstract

Tor soro is one of the most economically important native freshwater fish species in Indonesia. Nonetheless, the insufficient data regarding its salinity tolerance makes a thorough investigation of this issue imperative. This research was conducted to determine the effects of salinity on the growth and physiological response of Tor soro juveniles at optimum salinity levels. This study used Tor soro (total length: 5.0±0.08 cm; initial weight: 2.0 ± 0.06 g) with five salinity level treatments of, 0, 2, 4, 6, and 8 ppt, and the stocking density of 15 fish per aquarium (three replications). Fish were maintained for 30 days and fed with commercial aquafeed. In this study, the best growth was found in 2 ppt (length gain: 0.37 ± 0.05 cm; weight gain: 0.23 ± 0.01 g; specific growth rate in length: 1.38 ± 0.16 % day-1; specific growth rate in weight: 0.78 ± 0.05% day-1) which is significantly higher than 4, 6, and 8 ppt (p<0.05), but it is not significantly different from 0 ppt (p>0.05). The results of the physiological response showed that there were no significant stress responses in Tor soro juvenile for all salinity treatments (p>0.05). there was no effect of 2 ppt salinity on the growth parameters compared to controls, but salinities above ppt had a significant detrimental effect. Exposure to salinities did not have any stress effect as shown by physiological indicators.

Abstract

Desentrasilasi dalam sebuah sistem ketatanegaraan sebuah negara bertujuan untuk menggerakkan roda pemerintahan agar tercapainya pemerataan dari berbagai bidang yang digerakkan oleh pemerintahan eksekutif. Pemberlakuan sistem desetralisasi ini berlaku untuk semua negara (negara-bangsa) dalam kerangka pembagian wilayah kekuasaan (local government). Sistem hukum Eropa kontinental adalah salah satu sistem yang memberi pengaruh terhadap sistem hukum Indonesia, yaitu dengan menjadikan peradilan administrasi sebagai elemen penting dari konstitusi negara yang sah. Persoalan penyalahgunaan wewenang oleh otoritas publik memunculkan Hukum Tata Usaha Negara yang memeberikan dampak perubahan terhadap kewenangan mutlak dari Pengadilan Tata Usaha Negara yaitu dengan memberikan kewenangan kepada Peradilan Tata Usaha Negara untuk mengambil keputusan. Pada prinsipnya Peradilan Tata Usaha Negara memiliki yurisdiksi penuh hanya dalam lingkup keputusan tata usaha negara saja (beschikking). Namun pasca ditetapkannya Undang- Undang Nomor 30 Tahun 2014 Tentang Administrasi Pemerintahan menjadikan Pengadilan Tata Usaha Negara berubah kewenangan dan arti Keputusan Tata Usaha Negara yang menjadi gugatan dalam penyelenggaraan pemerintahan.
