Abstract

Rice plants frequently encounter both biotic and abiotic stress because the nation is tropical. Through the application of ecologically friendly technology, the sustainability of diminishing rice production can be addressed. Trichoderma spp. microorganisms used in biopriming may be able to address the issues that come up. The purpose of the research is to determine how bio priming using Trichoderma spp. affects the viability and vigor of seeds from several rice varieties. (Oryza sativa L.). This study employs an experimental approach with a Completely Randomized approach (CRD) factorial design that includes two factors: the rice variety and the concentration of Trichoderma spp. Two-way analysis of variance (ANOVA) was used to analyze the data. The findings of the study show that seed vigor and viability are significantly impacted by biopriming with Trichoderma spp. For the Kusuma 05 rice variety, the treatment with Trichoderma spp. at a 30% concentration showed the largest increase in each variable.

Abstract

The prospects for pig farming in Bajawa are very promising, in line with the economic growth and the development of business centers that directly or indirectly support the increase in demand for pork. Several methods can be employed to improve the productivity of pigs in the grower-finisher phase, one of which is through feed improvement by providing alternative ingredients that can enhance nutrient utilization, such as turmeric powder (curcuminoid) as a feed additive. The purpose of this study is to examine the effects of turmeric powder (curcuminoid) supplementation at various levels in the basal diet on weight gain, feed intake, and feed conversion to determine the optimal level of turmeric powder supplementation in the basal diet and to analyze the economic benefits of using turmeric powder as a natural feed additive. The method of this research is an experimental method where there are 4 treatments and 3 replications between pigs given feed with turmeric powder and pigs given feed without turmeric powder. The variables observed include feed consumption, weight gain, and feed conversion. The level of turmeric powder addition in the basal diet affects the weight gain of pigs and the feed conversion value. Treatment R4 (85% feed and 15% turmeric powder) is the most optimal treatment. The research also shows a significant difference in the weight gain results of the pigs among each treatment, and there is a positive relationship between feed conversion and the weight gain of the pigs with a strong correlation category.

Abstract

Bamboo is a non-timber forest product (NTFP) commodity that has high SEE (Social, Economic and Ecological) benefits for meeting community needs and as a soil and water conservation commodity. However, the bamboo population is currently relatively small because bamboo development is still not optimal either by the government or the community, and especially the community thinks that bamboo is only used or exploited by lower class people and has little economic value. Currently, bamboo is used as an industrial tree or commodity with high economic value and industrial demand is relatively high, so its population needs to be increased, especially by the community, because bamboo cultivation is relatively easy and does not require large investments. Basically, the feasibility study for the technical, social and ecological aspects of bamboo cultivation used in this research is to carry out an analysis of the environmental conditions of the bamboo development area in Golewa District, Ngada Regency. This analysis then produces recommendations for the feasibility of developing bamboo cultivation at that location, in this way it will be possible to obtain things that are obstacles in the technical development of bamboo cultivation in Golewa District, Ngada Regency. The results of this research show that technically the development of intensive bamboo cultivation has the potential to be considered feasible because it has human resources that are ready to be trained, good physical infrastructure is available, and communication networks are already available. However, there are several notes to pay attention to, namely that human resources who have knowledge about intensive bamboo cultivation are still limited. It is necessary to carry out continuous counseling and assistance efforts for intensive cultivation and utilize available communication networks by establishing a market information system for bamboo trading.

Abstract

The rate of yield loss in rice plants has not changed much, over a period of 15 years. This loss process occurs at every stage of rice production, from harvesting, threshing, drying, transportation, milling and storage. In the process of threshing rice, many methods are used, among others, by means of threshing, stepping on, pedal thresser and power threser. From the results of research conducted at the Adaptation Test Location of Were III Village, South Golewa District, Ngada Regency, the rice threshing process is carried out using a thresher machine (power threser). The research method used is a qualitative research method, this is because the researcher analyzes the phenomena and events of loss of yield due to threshing that occurs in the field. Based on data from research results at the Adaptation Test Location of Were Village III, Golewa Selatan District, Ngada Regency, it can be seen that the percentage of yield loss obtained in this study was 13.5%, which is higher than the existing theory. This is supported by the conditions that occurred at the time of the study where there were many factors that caused a lot of yield loss in Ciherang varieties, including inadequate technology, not optimal use of time and frequent damage to the equipment used.Keywords: 3-5 keywords,  author guidelines; agriculture journal; article template  Keywords: yield loss, rice plants, factors INTISARITingkat kehilangan hasil pada tanaman padi masih belum banyak berubah, selama kurun waktu 15 tahun. Proses kehilangan ini terjadi pada setiap tahapan produksi padi, mulai dari panen, perontokan, pengeringan, pengangkutan, penggilingan dan penyimpanan. Dalam proses perontokan padi banyak metode yang dilakukan antara lain dengan cara gebot, diinjak, pedal threser dan power threser. Dari hasil penelitian yang dilaksanakan di Lokasi Uji Adaptasi Desa Were III, Kecamatan Golewa Selatan, Kabupaten Ngada, proses perontokan padi dilakukan dengan menggunakan mesin perontok (power threser). Metode penelitian yang digunakan adalah  metode penelitian kualitatif  hal ini dikarenakan peneliti melakukan analisis fenomena dan peristiwa kehilangan hasil akibat perontokan yang terjadi di lapangan. Berdasarkan data dari hasil penelitian di Lokasi Uji Adaptasi Desa Were III Kecamatan Golewa Selatan Kabupaten Ngada, maka dapat diihat bahwa persentasi kehilangan hasil yang diperoleh pada penelitian ini adalah sebesar 13,5% dimana hasil tersebut lebih tinggi dibandingkan dengan teori yang ada. Hal itu didukung dengan keadaan yang terjadi pada saat penelitian dimana terdapat banyak faktor yang menyebabkan terjadinya banyak kehilangan hasil pada tanaman padi varietas ciherang antara lain teknologi belum memadai, pemanfaatan waktu yang belum maksimal serta sering terjadi kerusakan pada alat yang digunakan. Kata kunci: kehilangan hasil, tanaman padi, faktor-faktor
