Judul: Precision farming of rice cultivation to increase rice productivity
Abstrak: Salah satu usaha untuk meningkatkan produktivitas padi sawah yaitu dengan pengelolaan pertanian secara cermat (precision farming), yang salah satunya yaitu dengan Perlekatan Pengelolaan Tanaman Terpadu (PTT). Penelitian ini bertujuan untuk melihat perbedaan budidaya antara cara petani, PTT pemerinatah, dan PTT cermat; melihat kualitas hasil panen dariketiga pengelolaan petani, PTT pemerintah dan PTT cermat; dan menigkatkan nilai ekonomi / keuntungan usaha tani padi sawah dengan membandingkan efisiensi input dari ketiga budidaya padi sawah.

Judul: Respon Petani terhadap Metode Pengelolaan Tanaman Terpadu (PTT) Padi di Desa Pancawati Caringin Bogor
Abstrak: Riceis a commodity that has been still the staple food of Indonesia so far. Riceis also acommodity that canaffect thesocio-economic conditions, andstate politics. However,related to the currentrice commodities in Indonesia, rice store that has suffered the drawback. Farmer sare required to participatein building the strength of the national food through increased productivity. The claimis often hampered by the powerlessness of farmers in the ability to apply (adoption) the technology. Integrated Crop Management (ICM) is one of the government's efforts to realize the successful achievement of sustainable self-sufficiency through increased productivity. ICM is a participatory holistic approach tailored to site-specific conditions. Therefore, it is not a technology package that must be applied by farmers in all locations. ICM goal is to improve the livelihoods of farmers through the application of appropriate technology to local conditions. The success of a program is influenced by knowledge, skills, and attitudes of actors/doers (farmers) in the field. Research to be conducted is expected to provide feedback information to the farmers' understanding towards this methods asthe efforts to increase rice productivity. This study took place in Pancawati village Caringin bogor. Research subjects in this study are all members of farmer groups in the Pancawati village Caringin bogor. The sampling technique used is using census technique, so the respondents in this study are the entire population of the 125 farmers. Data analysis in this study uses descriptive analysis and SEM (Structural Equation Model) by using PLS program. The analysisconducted inthis study, it can be concluded thatthe responsesof farmers towards this method in improvingrice productivityare good. This can be indicated byrespondents perceptions ofthe knowledge, skillsandgood attitude. Based on the SEM PLS,the knowledge and skills affect productivity but higher skills than the loading factor productivity of knowledge that is more influenced by the skills of farmers but farmers have not been able to make modifications because of conceptual knowledge or lack of knowledge that needed assistance because it involves the application of field and field of technical skills to be successful applying the method of PTT. In the long term knowledge is also needed so that farmers can provide innovation input, modify the method of PTT, PTT method helps application problems. It is shown by the different manner in which the attitude variable does not affect productivity.

Judul: Seroprevalence of Chikungunya and The Risk of Transmission Transmitted Among Blood Donors In Sulawesi-Indonesia
Abstrak: Chikungunya (CHIK) is an arthritogenic alphavirus in the Togaviridae family of arboviruses with an enveloped RNA containing a positive single-stranded 11.8 kb genome. Transmission occurs through the bite of infected Aedes mosquitoes, which are commonly found in tropical and temperate regions. Primary vertebrate hosts include monkeys and humans, in whom this virus replicates efficiently (Diallo et al. 1999). Chikungunya virus (CHIKV) is known for causing acute illness, manifesting with fever, rash, and arthralgia known as Chikungunya fever (Horwood dan Buchy 2015). Despite the high number of Chikungunya cases in Indonesia, comprehensive data are lacking in CHIKV seroprevalence. Previous studies reported the median seroprevalence of anti-CHIKV antibodies in all situations 18.5%, ranging from 0.0 – 73.% (Harapan et al., 2019). However, the gap in epidemiological data of CHIKV in many regions of Indonesia including Sulawesi, is noteworthy. The objective of this study was to determine the seroprevalence of CHIKV infection among healthy individuals from North and South Sulawesi using archive samples. Additionally, an asymptomatic course of CHIKV infection and the high pre-symptomatic viral load as 108pfu/mL (Appassakij et al. 2013) suggest that the infection can threaten blood transfusion safety. Evidence of CHIKV infection among blood donors (Simmons et al. 2016) indicates transfusion-transmitted is probable, although it has not been documented (Petersen dan Epstein 2014). Our study also aimed to test the archive blood donor specimens from North Sulawesi for CHIKV IgM and viremia to determine blood safety in endemic areas. Samples were screened for anti-CHIKV IgG antibodies to determine exposure to CHIKV using an in-house IgG ELISA as previously described (Kosasih et al. 2013) with minor modifications. CHIKV IgM, a marker for recent infection and endemicity, was tested in 303 samples randomly selected from IgG-positive samples using a Euroimmun anti-CHIKV IgM ELISA kit (Luebeck, Germany) following the manufacturer’s instructions. CHIKV RNA detection was carried out using one-step-qRT-PCR. The data generated were analyzed with IBM-SPSS v20 (IBM Corporation, USA). Chi-square (χ2) test to determine significant differences between categorical variables, and a p-value less than 0.05 was considered statistically significant. As many as 1092 serum and plasma samples were analyzed, with CHIK IgG seropositivity at 53.48% (584/1092). The results also show a statistically significant difference in the seropositive rates based on gender (58.8% male and 48.5% female) and region (53.9% South Sulawesi versus 48.7% North Sulawesi). Seropositivity increased with age; approximately half of adults between their 40s and 60s had seroconverted. Most of the participants, 304 (27.8%), were between 21-30 years. The age groups with the least participants were those >60 years and <20 years, with 93 participants each (8.5%), followed by the 51–60-years age group with 142 (13.0%) participants. In addition to IgG, the overall anti-CHIKV IgM seropositivity comprised 12.9% (39/303). A Chi-square analysis shows a statistical significance of anti-CHIKV IgM seropositivity based on gender and region with p-values (p=0.047 and p=0.038, respectively). On the contrary, there was no significant difference in anti-CHIK IgM based on age. The age group with the most participants was the 21-30 years with 19.3% (16/83), while those with the least participants were those >60 years. The current study
