Abstract

White oyster mushroom (Pleurotus ostreatus) is a type of wood fungus that can be consumed and has high nutritional content such as carbohydrates, calcium, protein, iron, fat, potassium and phosphorus. This study aims to determine the benefits of oyster mushroom growth and production (Pleurotus ostreatus) using various compositions of growing media that incorporate coffee grounds. The study was conducted from June to December 2024 at the oyster mushroom cultivation facility of the Faculty of Agriculture, Christian University of Indonesia Toraja, located in Tallunglipu District, North Toraja Regency. The research consists of three stages: the production of oyster mushroom baglogs with coffee grounds as an additional substrate, testing the effectiveness of coffee grounds as a supplementary substrate in the growing media for oyster mushrooms, and analyzing the farming business based on the production results of oyster mushrooms. The research method employed a Randomized Block Design (RBD) with five treatments: without additional coffee grounds (0%); with additional coffee grounds at 5%, 10%, 15%, and 20%. The results indicate that the treatment with 10% coffee grounds yielded the best results, with an average of 35.67 caps, a cap diameter of 9.38 cm, a stem diameter of 1.78 cm, and a mushroom weight of 391.00 grams.

Abstract

Collaboration, communication, and creativity are all work qualities that must be had by someone. These abilities, however, are still missing in students who will graduate and be ready to work. Students will work together in groups to complete tasks, becoming acclimated to working in teams, communicating in teams, and expanding their creativity in the process. The goal of this study is to use project assignments in the classroom to help students enhance their collaboration, communication, and creativity skills. The Nonequivalent Post Test Only Control Group Design is used in this type of study to create a quasi-experimental design. The experimental class and the control class were employed as research samples in this study. Students' collaboration, communication, and creativity skills in the experimental class were higher than in the control class, according to descriptive statistical analysis. Implementing tasks has an influence on developing students' communication abilities and creativity, according to inferential statistical research. In terms of collaboration skills, it appears that they have little bearing on the execution of project duties.

Abstract

This research aims to analyze the effect of organic fertilizer from chicken waste compost mixed with roasted husks and runny water on the quality of the fertilizer and the growth of green mustard greens (Brassica juncea). The method used was a randomized block design (RAK) with treatments consisting of K0 = Control, K1 = 10 Tons/Ha (50 gr/polybag), K2 = 20 Tons/Ha (100 gr/polybag), K3 = 30 Tons/Ha (150 gr/polybag), and K4 = 40 Tons/Ha (200 gr/polybag). Each treatment consisted of 75 plants divided into 5 plots, with each plot containing 15 plants. The research results showed that compost fertilizer with a concentration of 100 gr/polybag provided the best effectiveness in increasing the growth of mustard greens, as seen from plant height (33.63), number of leaves (11.67), and plant weight (157.67), compared to other treatments. This research also provides solutions for managing livestock waste and supporting sustainable agriculture. Using compost is safer than chemical fertilizer, can maintain moisture in plant roots, and does not damage the environment.

Abstract

Limbah cair menimbulkan dampak lingkungan yang serius apabila tidak dikelola dengan baik. Limbah cair berpotensi besar menurunkan kualitas dan kesehatan lingkungan hidup. Setiap aktifitas manusia akan menghasilkan limbah. Limbah yang dihasilkan berdasarkan teksturnya dibagi menjadi limbah padat dan limbah cair; sedang berdasarkan ketahanannya dalam lingkungan dikelompokkan menjadi limbah yang dapat didegradasi dan limbah yang tidak dapat didegradasi. Baik limbah padat maupun limbah cair yang tidak dapat didegradasi itulah yang bermasalah bagi lingkungan. Tujuan dari penelitian ini adalah untuk mengetahui komposisi kandungan unsur kimia dalam limbah yang ada di TPA Karua, Toraja Utara, Sulawesi Selatan. Limbah cair yang diteliti adalah limbah cair di petak instalasi penampungan limbah cair yang berada di lahan areal TPA Lembang Karua, Kecamatan Balusu, Kabupaten Toraja Utara. Berdasarkan hasil penelitian intalasi penempungan limbah cair yang berada TPA Lembang Karua menunjukkan bahwa pada intalasi penampungan limbah cair pH (atas 6,7, tengah 6,5, dan bawah 4,5), Nitrogen ( petak atas 0,025%, petak tengah 0,025%, dan petak bawah 0,035%), Pospor (petak atas 0,555 ppm, petak tengah 0,075 ppm, dan petak bawah 0,04 ppm), Kalium (petak atas 400 ppm, petak tengah 250 ppm, dan petak bawah 250 ppm), TDS (petak atas 345 mg/L, petak tengah 287 mg/L, dan petak bawah 217,5 mg/L), BOD (petak atas 42,93 mg/L, petak tengah 67,83 mg/L, dan petak bawah 93,43 mg/L), dan COD (petak atas 140 mg/L, petak tengah 218 mg/L, dan petak bawah 340 mg/L).
