Abstract

The purpose of this study was to produce an E-Module on ecology and environmental change using a guided inquiry approach that is valid, practical, and effective. This type of research is development research using the Plomp model. The development phase of this model begins with the Preliminary research phase, the Development or prototyping phase, and the Assessment phase. The instruments used in this study were validity assessment sheets, practicality assessment sheets, and competency assessment sheets for knowledge, skills, attitudes, motivation, and science process skills. The results showed that the E-Module on ecology and environmental change using a guided inquiry approach based on the expert judgment was very valid with a value of 97.59%. The practicality assessment by the teacher obtained a score of 95.83% with very practical criteria and a student assessment in the field trial (large group evaluation) with a score of 90.45% with very practical criteria. The results of the effectiveness test found that the class using the E-Module on ecology and environmental change with the guided inquiry approach had higher scores than the class that did not use the E-Module, so the use of the E-Module with the guided inquiry approach supplemented with pictures, animations and videos could help students understand the material. It can be concluded that the E-Module on ecology and environmental change with the guided inquiry approach that has been developed is in the category of very valid, very practical, and very effective in improving student learning outcomes.

Abstract

Policy reforms and research on agricultural ecology need to be intensified to reduce land damage and the massive ecological and chemical impacts of soil pollution. This is related to the increasing population that requires clothing, food and welfare. Furthermore, although there has been a shift towards a form of agriculture with high added value. This problem must be found a solution by diversifying efforts, ecological applications on agricultural cultivation land and making breakthroughs in making organic fertilizers with various sources and environmentally friendly ways. This is rational and can be done by involving the industry, universities and farmer groups who are smart and productive. The results of community service as many as 34 respondents were interested in making NPK liquid fertilizer. Keywords: NPK Liquid Fertilizer, MNBs, Community Service

Abstract

In the hydroponic system, AB Mix nutrition is one of the standard nutrients used. In addition to the use of AB Mix, the use of ecoenzymes in hydroponic plants is also a big concern. This is what makes the authors interested in using ecoenzyme to help AB Mix for hydroponic growth and maintenance of pakcoy (Brassica rapa L.). This study aims to determine the effect of spraying ecoenzyme on the growth of pakcoy (Brassica rapa L.) which is cultivated hydroponically. This research will be carried out from December 2021 to February 2022 at the Plant Physiology Laboratory and the wire house of the Biology Department, FMIPA UNP. This study used a completely randomized design (CRD) with 5 treatments and 5 replications. Consists of: P1 (Control), P2 (1mL ecoenzyme + 1 L water), P3 (2mL ecoenzyme + 1 L water), P4 (3mL ecoenzyme + 1 L water), P5 (4mL ecoenzyme + 1 L water). The data obtained were analyzed by means of variance (ANOVA) with DMRT further test. The results of the study of spraying ecoenzyme on pakcoy (Brassica rapa L.) which were cultivated hydroponically had an effect on plant height growth with the highest average of 14.4 cm, and had no effect on leaf area.

Abstract

Spinach is one of the vegetables favored by the people of Indonesia and also has high nutritional value. Spinach can be cultivated conventionally or hydroponically. Hydroponics is one solution to the problem of limited land in farming that uses water as a nutrient medium that will be directly absorbed by plants to support plant growth. Hydroponics uses Ab-Mix nutrients. To get better results, ecoenzyme can be used as a support for plant fertilizers. This study aims to see the effect of spraying ecoenzyme on the number of spinach leaves. This study is an experimental study consisting of 5 treatments and 5 replications with a dilution of ecoenzyme solution, P1 (control), P2 (2mL ecoenzyme + 1L water), P3 (3mL ecoenzyme + 1L water), P4 (4mL ecoenzyme + 1L water), and P5 (5mL ecoenzyme + 1L water). The data obtained were analyzed by means of variance (ANOVA) with Duncan's New Multiple Range Test (DNMRT) further test. The results showed that spraying ecoenzyme on spinach plants had no effect on the number of plant leaves.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh media cangkok dan mengetahui jenis media yang dapat meningkatkan pertumbuhan akar terhadap pertumbuhan cangkokan tanaman buah ajaib (Synsepalum dulcificum). Penelitian ini dilakukan dari bulan Desember 2021 hingga bulan Februari 2022 di tempat pembibitan bonsai yang berada di jalan Bandes, Parak Jigarang, Kec Kuranji, Kota Padang. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 3 perlakuan dan 6 pengulangan. Faktor yang diuji adalah macam media cangkok yang meliputi: media lumut, cocopeat dan tanah. Data yang dianalisis menggunakan Anova dilanjutkan dengan uji Beda Nyata Terkecil (BNT) pada tingkat kepercayaan 5%. Hasil menunjukkan bahwa penggunaan media cangkok yang berbeda berpengaruh terhadap pertambahan jumlah akar dan rata-rata panjang akar, dimana penggunaan media lumut memberikan hasil yang tertinggi pada jumlah akar dan rata-rata panjang akar. Jumlah akar pada perlakuan media lumut berbeda dengan media cocopeat dan tanah, tetapi perlakuan media cocopeat tidak berbeda dengan media tanah. Rata-rata panjang akar pada perlakuan menggunakan media lumut berbeda dengan media cocopeat dan tanah, tetapi perlakuan media cocopeat tidak berbeda dengan media tanah.

Abstract

Water pollution is a deviation of the properties of water from normal conditions. Water that is polluted by pesticide residues when it has reached a certain concentration will greatly affect the environment and the aquatic organisms that live in it. Fish is one of the aquatic biota that can be used as an indicator of the level of pollution that occurs in the waters. Fish that have been contaminated with contaminants such as hazardous materials for a long time will experience changes in structure or function and will also experience changes in histological conditions. Therefore, any changes that occur in the aquatic environment will directly or indirectly affect the gills both structurally and functionally. This type of research is research that uses the literature review method. The stages of literature collection used in this study refer to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. This stage consists of four procedures, namely, identification, screening, eligibility and acceptance. This study shows that water pollution greatly affects the histopathology of fish gills because it can cause several disorders and diseases of fish gills. Key words : Water Pollution, Fish, histopathology of fish gills
