Digitized learning materials offer students meaningful classroom learning experiences that may actively engage the students in the learning process toward holistic development. Hence, this action research aimed to determine the effectiveness of the Digitized Teaching Strategy (DigiTS) in improving the English language performance of Grade 8 students in Gen. Tiburcio de Leon National High School using researcher-made tests and group discussions. Participants were 60 Grade 8 students divided into two groups-the control group who received the traditional method of teaching and the experimental group who were exposed to the Digitized Teaching Strategy. The study employed a mixed method research design which included pre-test, post-test, and Focus Group Discussion. Data were analyzed quantitatively using appropriate statistical treatment and qualitatively through coding and categorizing. Findings of quantitative data analysis revealed that both the traditional way of teaching and Digitized Teaching Strategy (DigiTS) improved the English language performance of the students as shown by the mean scores during pre-test and post-test. However, the performance of the experimental group had no significant difference to the performance of the control group based on the statistical computation. On the other hand, qualitative data analysis had identified three recurring themes-development of basic language skills, motivation for positive learning engagement, and teachers’ involvement in learning. Though participants agreed that DigiTS was an engaging way of teaching and learning that could develop their English macro skills, students believed that teachers’ in -depth discussion is necessary to ensure mastery of the lesson. The study recommends that teachers in different disciplines must familiarize the process of crafting potential materials to cater 21st century learners’ needs. The Digitized Teaching Strategy (DigiTS) can also be used to aid teachers on lesson delivery to ease their teaching tasks without compromising the quality.

Agrosilvopastoral is a type of agroforestry that combines woody and non-timber crops, as well as animal husbandry/fisheries components. The agroforestry pattern in Tamiajeng Village belongs to the agrosilvopastoral type with components of jabon trees, mango banana trees and catfish ponds. The survey results showed that there was an interaction between the components of the observed agrosilvopastoral. Jabon and manga trees serve as shade for catfish ponds because catfish eggs need shade to hatch. The observations also showed the presence of dominant plant-disturbing organisms, such as fusarium wilt on bananas and sooty mildew on manganese. Integrated and sustainable control can be carried out by removing banana plants that are affected by disease and are no longer producing and can be used as catfish feed because banana stems have a function as additional nutrition and prebiotics for catfish. Controlling sooty mildew disease can be done by increasing air humidity in the presence of fish ponds so as to suppress the spread of conidia Capnodium sp sooty mildew fungus on mango leaves. Fish pond water can also be used as organic fertilizer for plants because it contains elements of nitrogen and phosphorus.

Walang sangit is one of the potential pests which at certain times becomes an important pest. These pests can cause yield losses of up to 50%. It is estimated that a population of 100,000 heads per hectare can reduce yields by up to 25%. This research on the intensity of the pest attack was aimed at knowing the categories of attacks on land owned by farmers in Karangnangka Village and finding out more environmentally friendly control methods. The number of plants observed every week was selected as many as 30 points (clumps) marked by pieces of bamboo or wood with a diagonal pattern. Data collection started by counting the number of plants in one clump at each sample point, then continued by counting the number of grains in each clump, and the last data was the number of seeds that were attacked or damaged in each clump. Then increase the attack intensity calculated using the absolute attack intensity formula. Calculations show a decrease every week, with values ??of 4.84%, 5.99%, and 6.60% sorted from the first observation to the third week. The control that can be applied is the use of animals (crabs) as traps to attract pests such as stink bugs.
Walang sangit是一种潜在的害虫，在某些时候会成为重要的害虫。这些害虫可造成高达50%的产量损失。据估计，每公顷10万头的数量最多可使产量减少25%。这项关于虫害强度的研究旨在了解Karangnangka村农民拥有的土地遭受虫害的种类，并找出更环保的防治方法。每周观察植物的数量被选择为多达30个点(丛)，用竹片或木片以对角线图案标记。数据的收集开始于在每个样本点计算一个簇中的植物数量，然后继续计算每个簇中的颗粒数量，最后的数据是每个簇中被攻击或损坏的种子数量。然后利用绝对攻击强度公式计算出的攻击强度增大。计算显示每周都在减少，值为??分别为4.84%、5.99%和6.60%，从第一次观察到第3周。可以采用的控制方法是利用动物(螃蟹)作为陷阱，吸引臭虫等害虫。

Purple spot disease is one of the main diseases in leaf onion cultivation. One form of control is carried out by utilizing neem plants, especially the neem leaves which have the potential as vegetable pesticides (fungicides). This study aims to determine the effectiveness of neem leaf vegetable pesticide and to obtain the right concentration of neem leaf vegetable pesticide in controlling purple spot disease on a leaf in rainfall season. This study used an experimental method designed in a single factor Completely Randomized Design (CRD) using neem leaf pesticide consisting of three treatments (control, 10%, and 20%). The results showed that neem leaves at a concentration of 20% were effective as a vegetable pesticide to control purple spot disease on leaf onion. Neem leaf vegetable pesticides at a concentration of 20% were able to inhibit the increase in the area of attack symptoms and also inhibit the intensity of purple spot disease attacks on leaf onion by 13.84%. This is caused by the increase in concentration causing an increase in the content of the active ingredient in the substance which functions as a pesticide that is able to inhibit the spread of large quantities.
