Abstract. Safitri YA, Hasanah U, Salamiah, Samharinto, Pramudi MI. 2019. Distribution of major diseases of shallot in South Kalimantan, Indonesia. Asian J Agric 3: 33-40. Shallot is a vegetable crop with high economic value, but its productivity in Indonesia is still relatively low. One of the causes is due to attack of the diseases. The research was conducted from November 2017 to April 2018, with the purpose of studying the distribution of major diseases of shallots in South Kalimantan. It consisted of field, laboratory, and greenhouse research. Field research involved the survey of shallots’ extensive planting in eight villages of six districts in South Kalimantan, disease symptoms, the broad of attack, and the collection of secondary data. Laboratory research included the isolation and identification of the pathogen causing diseases. The greenhouse research was conducted to perform the Postulate Koch test. The research result showed that there were two major diseases of shallots, namely Moler and Anthracnose. Pathogen causing Moler disease (Fusarium oxysporum) attacked shallot plant in six districts (Tabalong, Balangan, Tanah Laut, Kotabaru, Tapin, and Banjarbaru) and pathogen causing Anthracnose disease (Colletotrichum sp) attacked shallot plant in five districts (Tabalong, Balangan, Tanah Laut, Kotabaru, and Tapin).
Catastrophic climate changes that have a negative impact in various fields including agriculture. The research objective is "Potential Mapping Agricultural Commodities to Mitigation of Food Problem in the Future". The research method is quantitative and qualitative. Methods of data collection using field research and literature. The population and the sample is a land unit and village units. Land units determine the suitability of land. The village unit collects socio economic data. The analysis technique used Location Question, Shift Share, Focus Group Discussion and spatial analysis. Spatial analysis using Arc GIS. The findings can be used to mitigate future food problems and analyze policies. The results showed rice plants has S1 class (Very Suitable). Corn, chili, orange and banana land suitability S2 (Suitable), onion is S3 (Marginal Suitable). Priority 1 rice commodity in Ayuang Village. Priority 2 Corn in Banua Binjai. Priority 3 that Chilli in the village of Awang Besar. Results LQ corn and chili have bases sector, other sectors have the non-base. Shift-share value is negative (-) except Chili. FGD results show developed commodity rice, corn, and chili. The development of leading sectors followed by marketing and processing can increase revenue. Limitations of the research do not examine pests that have the potential to cause crop failure.
The learning of listening to the story of the child has been given to the students of grade VI of SD Negeri 020Tembilahan Hilir. However, the existing picture shows that classically, the result only reaches an average of20% or is not satisfactory based on preliminary tests. This research is a classroom action research conducted byclass VI SD Negeri 020 Tembilahan Hilir with subject 20 people. Data collection techniques through tests andobservations. Then the analysis technique is done descriptively. The result of the research concludes that thestudents' learning achievement has increased. This is seen in the preliminary study of 20%, or only 4 studentsout of 20 students completed, in the first cycle increased to 50% because of 20 students 10 students, and in thesecond cycle increased by 85% of 20 students 17 students.
Cabai merah besar (Capsicum annuum L.) merupakan komoditas yang sangat dibutuhkan, khususnya dalam industri makanan dan kebutuhannya sering meningkat. Kebutuhannya yang meningkat tersebut berbanding terbalik dengan ketersediaan cabai yang tidak dapat terpenuhi. Penyebabnya antara lain adanya kendala serangan lalat buah (Bactrocera spp.) yang selalu terjadi pada tanaman cabai. Gejala yang ditimbulkan berupa adanya lubang kecil pada buah cabai, buah rontok dan terdapat larva di dalam buah. Pengendalian yang sering dilakukan adalah dengan menggunakan insektisida kimia yang dapat mengakibatkan pencemaran lingkungan. Salah satu solusinya adalah dengan pemanfaatan tanaman refugia. Penelitian ini dilakukan untuk mengetahui pengaruh tanaman refugia terhadap serangan lalat buah pada tanaman cabai dan efektifitasnya tanaman kenikir (Cosmos caudatus) dan marigold (Tagetes erecta L.) dalam menekan serangan lalat buah pada tanaman cabai. Rancangan yang digunakan adalah Rancangan Acak Kelompok (RAK) dengan 4 perlakuan, kontrol (T0), tanaman kenikir dan marigold ditanam bersama cabai (T1), tanaman kenikir ditanam bersama cabai (T2), tanaman marigold ditanam bersama cabai (T3) dan diulang sebanyak enam kali. Hasil pengamatan, tanaman refugia berpengaruh terhadap serangan lalat buah. Tanaman refugia jenis marigold, intensitas serangan lalat buah mencapai 6,01% dan 19,30%, sedangkan jenis kenikir intensitas serangannya mencapai 13,61% dan 33,61%.
