Abstract

Hormone gibberellin (GA3) is known to be able to increase yield and plays a role in the production of seedless fruits. This research was conducted to determine the effects of GA3 application on yield and quality (seed number) of watermelon. The research was performed at the experimental farm of Agriculture Faculty, University of Halu Oleo.  The research was arranged in a Complete Randomized Design (CRD) with a single factor (dose of GA3), consisted of 6 (six) levels, namely:  without GA3 application (G0), GA3 100 mg L-1 (G1),  GA3 150 mg L-1 (G2),  GA3 200 mg L-1 (G3),  GA3 250 mg L-1 (G4), and GA3 300 mg L-1  (G5).  Each treatment consisted of 4 (four) plants, with 3 replicates, to make an averall 72 experimental units (plants).   Research results showed that the application of GA3 significantly influenced the fresh fruit weight, fruit diameter, fuit content diameter, and seed number.   Treatment of gibberellin 300 mg L-1 (G5) tended to produce higher yield (fresh fruit weight, fruit diameter, fuit content diameter), while G4 treatment (250 mg L-1) resulted in the lowest number of seeds in the fruit.   Despite further research is still needed, this research indicates that the application of gibberellins (GA3) has the potency in increasing the yield of watermelon and improving the quality, in term of the possibility to produce seedless watermelon. Keywords: gibberellins (GA3), fruit yield and quality, seedless fruit, watermelon.

Abstract

Biodiversity is high value genetic resources required for the good of human being. Globally, biodiversity has been degraded into a danger level.   Identification of problems, alternative solutions to protect, to conserve, and to utilize the biodiversity is a primary priority. The utilization of local rice cultivars, as a source of germplasm for rice breeding programs must get special attentions to protect the germplasm from vanishing. Biotechnology or genetic engineering technology provides an alternative way and a short cut in manipulating and producing improved plant varieties.  Different kinds of methods can be used to genetically engineer plant species. Since 1980s and ever since, many achievements and improvements have been made by scientists around the world in the area of genetic engineering, including genetic improvement of rice crops.   As an example, scientists have engineered transgenic rice crops that contain pro-vitamin A in the endosperm.  Pro-vitamin A is a substance that does not naturally occur in rice, but is urgently required to prefend human’s eye blindness. Another example, recently a group of scientist has developed super- rice strain that defies triple whammy of stresses (drought, salty-soils, and lack of fertilizer) simultaneously. Keywords: Biodiversity, biotechnology, genetic improvement, and local rice cultivars

Abstract

Kurang  responsifnya eksplan  terhadap  medium  invitro  dan  efisiensi  transformasi yang relatif rendah merupakan kendala umum yang dihadapi pada transformasi genetik tanaman legum.   Pada tanaman lupin, satu spesies legum, sebagian besar klon yang diperbanyak dari satu tunas transgenik (single transformation event) sering tidak mengandung gen yang ditransfer (transgene), dan menghasilkan keturunan yang tidak transgenik, walaupun awalnya plantlet tersebut terbukti transgenik. Kimera (chimerism) diduga sebagai penyebab dari penyimpangan segregasi gen (reduced transgene segregation) ini.  Penelitian ini mencoba untuk membuktikan isu kimera tersebut. Uji in-situ PCR dan uji histokemikal GUS & lokalisasi selular dari transgen (dalam hal ini gen gus) dilakukan untuk mengetahui apakah dan dimana transgen tersebut terekspresi pada tunas lupin trasngenik generasi T0  tersebut.   Uji in-situ PCR dan histokemikal GUS menunjukkan bahwa GUS umumnya terekspresi pada beberapa bagian dalam batang tunas (plantlet T0) dan tidak tersebar merata. Hasil ini memberikan bukti struktural yang penting bahwa transgen terekspresi  secara  sektorial  pada  tunas  lupin  generasi  T0.    Ini  sekaligus  membuktikan bahwa tunas lupin generasi T0  benar-benar kimera, dan menjadi penyebab penyimpangan segregasi transgen pada generasi T1.   Upaya-upaya perlu dilakukan untuk mengurangi kejadian kimera ini, sekaligus mendapatkan ekspresi gen yang solid pada tunas (plantlet) lupin (solid transformant). Key words:   Chimera, transgene segregation, in-situ PCR, GUS histochemical assay

Abstract

This Research aimed at grouping of Xanthomonas oryzae pv. oryzae pathotypes in rice cropping center of Southeast Sulawesi using isogenic lines of IRRI, as well as to know the Xanthomonas oryzae pv. oryzae pathotypes dominating and spreading in rice cropping center of Southeast Sulawesi. The pathotype grouping was determined by leaf innoculated cutting method using 30 isolates of Xanthomonas oryzae pv. oryzae from Southeast Sulawesi in 10 isogenic lines, namely IRBB1, IRBB2, IRBB3, IRBB4, IRBB5, IRBB7, IRBB10, IRBB11, IRBB13, and IRBB21. Each isolate was inoculated on the 10 isogenic lines and repeated twice. Observation  of disease intensity was conducted randomly on five leaves at four weeks after inoculation. The disease intensity was measured by the ratio of the length (cm) of leaf blight symptom to total the length of leaf sample (cm). The research results indicated there were seven pathotypes of Xanthomonas oryzae pv. oryzae in Southeast Sulawesi, i.e : pathotype X, XI, XII and four new pathotypes. Pathotype XII was the dominant pathotype, abort 79.31% of the total isolates and spreading in three regencies, Kolaka, Konawe, and South Konawe. Keywords: bacterial leaf blight, Xanthomonas oryzae pv. oryzae, pathotype

Abstract

Abstract Citrus Vein  Phloem Degeneration (CVPD) is  one  of  the  most important diseases of citrus. Worldwide and national yield losses of citrus production due to this disease infection have been very significant.   This research ultimately aimed at producing citrus stocks through in-vitro culture, and free of CVPD.  Citrus seeds were used as explant and cultured on MS and WPM in-vitro media, supplemented with malt extract. Citrus plantlets were tested for the presence of  CVPD DNA using CVPD specific primers in PCR reactions.   Research results showed that MS basal medium supplemented with malt extract was quite good for in- vitro production of citrus plantlets. Plantlets were negative for CVPD infection based on PCR tests.  CVPD-free seedlings (Citrus reticulata) have been grafted with citrus rootstock (Citrus sinensis).  Grafted citrus seedlings were also proven to be negative for CVPD infection based on similar PCR tests.  Citrus seedlings/stocks produced by in-vitro culture, and free of CVPD, are now available for further growth. Keywords: Citrus Vein Phloem Degeneration (CVPD), in-vitro culture, PCR

Abstract

The Internal Partnership Program (PKMI) for faculty service is conducted in Warambe Village, Parigi District, Muna Regency, Southeast Sulawesi, with the target audience being the Labotoro Farmers Group. The issues encountered by the farmers' group include poor soil fertility, specifically low-quality land, and a lack of knowledge regarding the production of organic fertilizers based on secondary vegetation. Additionally, there is a significant amount of agricultural waste and secondary vegetation available, but they have not been maximally utilized as raw materials for enhancing soil fertility and as a nutrient source for corn plants due to a lack of knowledge in this area. The proposed solution and targets are to provide technical guidance and demonstrate the production of organic fertilizers for soil fertility enhancement, as well as to transfer this technological innovation to the farmers. The dissemination and adoption process of this technology is expected to increase farmers' income through increased production of yellow corn crops. The results obtained from the provided solution include an 85% increase in the understanding and knowledge of the members of the farmers' group regarding the utilization of secondary vegetation for organic fertilizer and soil fertility enhancement in their corn fields. The technology of utilizing secondary vegetation has not been previously implemented by the partner group, so this activity has contributed to the farmers' knowledge and skills in improving land productivity, especially within the Labotoro Farmers Group

Abstract

This study aims to determine the effect of the application of various types of manure on the production of mung bean. The research was carried out at the Field Laboratory of Experimental Gardens II, Faculty of Agriculture, Halu Oleo University, Kendari, from October to December 2021. The study used a randomized block design consisting of four treatments, namely control (P0), cow manure 10 t ha-1 (P1), goat manure 10 t ha-1 (P2) and chicken manure 10 t ha-1 (P3). Each treatment was repeated 4 times so that there were 16 experimental units. Variables observed were number of pods, pod weight, seed weight, weight of 100 seeds, seed production ton ha-1, analyzed by variance. If the variance shows a significant effect, then proceed with the Least Significant Difference Test (BNT) at the 95% confidence level. The results showed that the application of manure can increase the production of mung bean plants. Treatment of chicken manure 10 t ha-1 (P3) gave a better effect on the number of pods, pod weight, seed weight and seed production t ha-1.

Abstract

The manufacture and application of compost fertilizer and POP technology (organic fertilizer plus) was carried out in the community in Alebo Village and/or Masagena, Konda District, South Konawe Regency, both for non-productive communities and owners of livestock waste processing. Alebo and Masagena villages are vegetable and annual crop farming areas, which are cultivated throughout the year and generally depend heavily on chemical fertilizers. Therefore, POP and/or compost technology is needed to improve the quality of soil nutrients and increase the production of healthy plants. In the villages of Alebo and Masagena there are abundant reservoirs for livestock waste and rice husks but they have not been processed optimally, but are only sold in the form of rice husks and raw cow husks at relatively cheap prices so that they do not provide added value for the village community, so this community service activity was done to improve environmental conditions which had been polluted due to the use of chemical fertilizers, and can also increase the income of local communities by utilizing existing waste to make organic fertilizer (compost and POP). Organic fertilizer has a higher price than livestock waste and unprocessed rice husks. The solution implemented in this service activity was the application of technology to change the use of chemical fertilizers by using POP technology and compost fertilizer so that farming land is even more productive.
