Mikoriza merupakan biostabilizer yang dapat ditambahkan untuk tanaman bertahan. Penelitian ini bertujuan untuk mengetahui pengaruh serta ada tidaknya interaksi pemberian mikoriza dan Trichoderma sp., terhadap pertumbuhan tanaman bawang merah varietas Crok Kuning (Allium cepa L. Aggregatum group) pada berbagai variasi frekuensi penyiraman. Jenis penelitian merupakan eksperimen dengan model Rancangan Acak Lengkap (RAL) dengan dua faktor yaitu pemberian mikoriza (tanpa mikoriza, mikoriza, Trichoderma sp., kombinasi mikoriza + Trichoderma sp.) dan variasi frekuensi penyiraman (setiap hari, 3 hari sekali, dan 6 hari sekali). Parameter pertumbuhan yang diamati adalah tinggi tanaman, jumlah daun, panjang akar berat segar dan kering daun, umbi, akar, dan persentase infeksi mikoriza. Analisis data menggunakan uji Two-Way ANOVA varian faktorial dilanjut uji Duncan apabila perlakuan mikoriza, frekuensi penyiraman, dan interaksi keduanya signifikan. Hasil menunjukkan bahwa tanpa pemberian Trichoderma sp., mampu meningkatkan berat segar daun, umbi, akar, dan berat kering akar, sedangkan perlakuan frekuensi penyiraman memberikan pengaruh terhadap berat segar dan berat kering akar. Adanya interaksi antara pemberian mikoriza dengan frekuensi penyiraman terhadap berat segar daun, berat segar umbi, berat segar akar, dan berat kering akar tanaman bawang merah.","PeriodicalId":370796,"journal":{"name":"Jurnal Penelitian Saintek","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129262262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The refugia used were marigold (Tagetes erecta L.) and long bean (Vigna unguiculata (L.) Walp.), while variations of the refugia placement were on the edges and in the middle of the rice planting. Each treatment consisted of 3 replicate plots. Observations of insects were carried out every 3 weeks in one planting season. The results showed that variations in the kind and refugia placement had a significant effect on insect abundance. The treatment of marigold refugia in the middle of rice planting has most potential in natural pest control because it has the highest natural enemy diversity index, so it can create a more stable agro-ecosystem.","PeriodicalId":370796,"journal":{"name":"Jurnal Penelitian Saintek","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130544227","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results of troubleshooting analysis and measurement of drive belt wear and tear are from the standard size of 19.50 mm to 18.00 mm, and the tolerance limit for use is 18.60 mm. As for the roller variation test results, using a lighter weight roller, for example, 8 grams and 9 grams, get maximum results at low and medium rotational speeds, compared to using an 11-gram roller (standard). The downside of this 8-gram and 9-gram roller is that it only gets good acceleration and torque at low rotational speeds. While at a high rotational speed less than the maximum. If we use an 11-gram roller, the acceleration and torque will get less than the maximum results but maximum power.","PeriodicalId":370796,"journal":{"name":"Jurnal Penelitian Saintek","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132940779","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
