Abstract

This community service took place in Simatohir Village, Padangsidimpuan District Angkola Julu, Padangsidimpuan City. The implementation methods used are counseling methods, cultivation technique training, and mentoring. The approach method used is: a) Counseling about the application of SRI technology. b) Make demonstration plots or demonstration plots. c) Use of 2 : 1 legowo planting system using ticks. In the generative phase clearly visible results from the application of SRI are applied to the rice field cropping. There is a distance that facilitates the care of farmers, efficiency in the use of paddy water and the number of productive tillers is 25-40 tillers / clumps and the yield reaches 1337 tons with an area of ​​1000 square meters and this difference is very obvious when farmers do not use SRI , which starts from tillage which is only extracted, unbalanced fertilization, irregular irrigation, perforated plants between 10-20 plants with productive tillers only 15-23 tillers. This will have an impact on harvest yields which only reach 900 kg with an area of​​ 1000 square meters.

Abstract

Rain is a very important factor in the availability of water for planting. Farmers still use the traditional method in determining the planting schedule. The determination is considered less than optimal. This study aims to analyze rainfall on sweet potato production in South Tapanuli Regency based on rainfall data, and determine the relationship between rainfall and the suitability of sweet potato plants. The research method used is survey method and literature review. This type of research is a survey method with a correlation and descriptive approach to see the relationship between rainfall and sweet potatoes which is used with correlation. From this research, the results of correlation and regression analysis of the rainfall variable on the sweet potato productivity variable for the last 10 years obtained from the Central Statistics Agency of South Tapanuli Regency describe a weak positive effect.

Abstract

Penelitian ini bertujuan untuk mengetahui peranan tinggi pemotongan dan pemberian pupuk bioboost terhadap pertumbuhan dan produksi padi salibu (Oryza sativa L.). Rancangan yang digunakan dalam penelitian ini adalah rancangan petak terbagi (split plot design) dengan 2 faktor yang akan diteliti yaitu: Faktor I peranan tinggi pemotongan (P) dengan 3 taraf yang di teliti yaitu: P1 = 5 cm ,P2= 10 cm, P3 = 15 cm. Faktor II pemberian dosis pupuk bioboost (B) yaitu terdiri dari 3 level yaitu: B0 = kontrol, B1= 25 ml/10L air, B2 = 25 ml/15 L air. Hasil penelitian menunjukkan interaksi perlakuan tinggi pemotongan dan pemberian pupuk bioboost penunjukkan pengaruh tidak nyata pada tinggi tanaman, jumlah anakan, jumlah malai, jumlah biji, dan berat biji per rumpun

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh pemberian beberapa bokashi pupuk kandang dan penggunaan beberapa jarak tanam terhadap pertumbuhan dan produksi tanaman Kacang Panjang (Vigna sinensis L.). Penelitian ini menggunakan metode Rancangan Acak Kelompok (RAK) dengan dua faktor yang diteliti yaitu faktor beberapa bokashi pupuk kandang dan faktor penggunaan beberapa jarak tanam. Hasil penelitian menunjukkan perlakuan pemberian beberapa bokashi pupuk kandang terhadap tinggi tanaman dan jumlah cabang pada umur 4 minggu setelah tanam menunjukan pengaruh yang nyata. Analisa secara statistik kedua perlakuan tidak menunjukan pengaruh yang nyata terhadap semua parameter yang diamati

Abstract

This study aims to determine the effect of storage room temperature and concentration of beeswax emulsions based on the physical-chemical properties of cucumbers (Cucumis sativus L.). The study used two factorial Complete Randomized Design (CRD) with each treatment four levels of treatment; each treatment was given two replications. The treatment at level 1 consisted of storage temperature (control, 25oC, 27oC, 30oC), the second level consisted of emulsion concentration (control, 6%, 12%, 30%). The parameters observed were texture, weight, moisture content, color, and shelf life. The results showed the interaction of storage room temperature and beeswax emulsion concentrations on cucumber texture, weight, water content showed no significant effect. The longest shelf life interaction is 12 days, while the shortest shelf life in six days. Keywords: Storage, Coiling, Cucumber Temperature
