Pemodelan topik pada dokumen paten terkait pupuk di Indonesia berbasis Latent Dirichlet Allocation

Introduction. Fertilizer is one of the most important production factors in the world of agriculture. It is crucial to increase the capacity of technology related to fertilizers. Analysis of patent documents can be one way to analyze technological developments, especially fertilizers. Data Collection Methods. The data used in this research are metadata, especially the title and abstract of a patent document in Indonesia. With the keyword "fertilizer," Patent metadata was processed in the 1945-2017 period. Data Analysis. The LDA model can provide a reasonable interpretation regarding topic modeling based on text data. Results and Discussion. The results find that degree of the patent title is better than the abstract of the patent. The LDA approach can adequately separate the topics of fertilizer patent technology so that it does not have multiple interpretations. Conclusion. Based on the findings, there are nine essential topics in the development of fertilizer technology. There is a phenomenon of the lack of technology collaboration between IPC technology sections.

Level Adoption Of Feed And Organic Fertilizer Technology Based on By Products of Oil Palm Plantation Industry In Lamandau District, Central Kalimantan

The main problem of livestock raising is feed, for that reason, the government issued an policy about integrated livestock farming with plants/plantations especially oil palm which has the potential to produce feed resources which was abundant, inexpensive, continuous, and does not compete with human needs. The activity was carried out in Lamandau District, Central Kalimantan Province. The objective of the research is to look at the level of adoption of complete feed technology from the by-products of the oil palm plantation industry and organic fertilizer in order to initiate the activities of palm oil - cattle integration. A total of 10 farmer groups, 3 individuals and 1 Livestock Breeding Center of Agriculture services were became cooperators. The business activities of cooperator were include animal husbandry, horticultural crop farming and oil palm plantations. The assessment of the level of adoption is done through interviews, Focus Group Discussions (FGD) and field monitoring, which are classified into 3 criteria, namely low (0.0 - 33.3%), moderate (33.4 - 66.7%) and high (66.8 - 100%). Introduction of technology and accompaniment activities were carried out for 3 years. The FGD activities involved various stakeholders such as the Regional Government, PBS of Palm Oil, Banking, and Farmer Groups. Direct practice is done for farmer group learning. The results of this study showed that in the first year only 1 farmer group adopted feed and organic fertilizer technology. The second-year the level of adoption of cattle feed was 33.33% with the range production of 5-20 tons/month, solid organic fertilizer 33.33% with the ring production of 3-20 tons/month and liquid organic fertilizer (biourine) 33.33% with the range production of 1,000-4,000 liters/month. The third-year the adoption level of cattle feed is 100% with the range production of 1-20 tons/month, 100% solid organic fertilizer with the range production of 1-20 tons/month, and 33.33% liquid organic fertilizer with the range production of 1,000-4,000 liters/month. The conclusion is the adoption of feed technology was greater, followed by organic fertilizer and finally liquid fertilizer technology. This is related to how important is its use in the field. Commitment of local government and PBS of palm oil is needed to help easily and continuously obtain feed and fertilizers materials of palm oil mill byproduct and facilitating marketing of their products.

THE EFFECTIVENESS OF INDIGENOUS ENDOMYCORRHIZA AND RHIZOBIUM INOCULUM IN INCREASING NUTRIENT UPTAKE AND YIELD OF SOYBEAN IN DRY LAND

Increasing the productivity of soybeans in dry land can be done by designing a package of fertilizer technology based on biological materials using indigenous endomycorrhiza and Rhizobium. The application of indigenous endomycorrhizal biofertilizer combined with Rhizobium is expected to be able to improve nitrogen and phosporus uptake so as to increase the productivity of soybeans in dry land. The experiment used two-factor factorial randomized block design. The first factor was dose of endomycorrhizal spores of Glomus that consisted of four levels, namely, treatment without endomycorrhiza inoculation, dose of 50endomycorrhizal spores, dose of 100 endomycorrhizal spores, and dose of 150 endomycorrhizal spores. The second factor was inoculation of Rhizobium inoculum that consisted of two levels, namely, treatment without Rhizobium inoculation and Rhizobium inoculation. The results showed that combination of 50 endomycorrhizal spores with Rhizobium inoculation gave the best effect on the number of effective root nodules per plant, endomycorrhizal infection per plant, nutrient uptake by plant, number of pods per plant, number of seeds per plant, and oven-dry weight of seeds per plant.

Segmenting Paddy Farmer's Attitude and Behavior

Agriculture is the major driving force of Malaysian economic. The aim of this research study is to segment the behavior of paddy farmers in Malaysia and understand how they influence adoption, a green fertilizer technology (GFT). The first objective of this chapter is to establish the thinking which enables a society to bridge the gap between embracing GFT among paddy farmer in Malaysia. Furthermore, the study builds the conceptual framework and examine the relationship among the relevant construct of this conceptual framework which was found by critically examining the different agricultural innovation literature. To make this conceptual framework robust it is found in the literature that theory of planned behavior and theory of reasoned action play a major role in segment farmer's behavior towards the adoption of GFT. Policy implications and/or suggestions for future research are deliberated for each issue and factor that affecting the adoption of GFT.
