Abstract

Abstract This study aims to determine the effect of compost and biochar fertilizer at a dose of 15 tons ha-1 made from livestock manure and its interaction on the growth and yield of red chili plants. This research was conducted in Blahkiuh Village, Abiansemal District, Badung Regency, Bali with an altitude of 400-500 m above sea level. This research was started from February 2020 to July 2020. The design used in this study was a factorial randomized block design (RBD) consisting of 2 factors, namely: chicken compost with 4 levels and biochar 2 levels by testing the types of compost and biochar. The interaction between the treatment effect with the type of compost and the type of chicken biochar had no significant effect on all observed variables. The treatment of compost application had a significant to very significant effect on most of the observed variables, except for the number of leaves, which had no significant effect. The treatment of chicken biochar dosing had a significant to very significant effect on most variables except for the maximum number of leaves and fresh weight per fruit, which had no significant effect. The results showed that the highest fresh fruit weight was obtained in the type of compost given by chicken livestock, namely 1499.56 g or an increase of 46.46% compared to the lowest treatment obtained without compost, namely 1023.85 g. To increase the growth and yield of red chili plants, it is recommended to use compost types of chicken livestock and chicken biochar at a dose of 15 tonnes ha-1 and further research is needed on the provision of biochar and compost types at different locations and types of plants. Keywords: compost, biochar, and chili plants.

Abstract

Spraying disinfectants is one of the efforts to prevent the transmission of COVID-19. One of the high needs for disinfectants can be overcome by using natural disinfectants or those made from natural ingredients, such as the use of eco-enzymes. The problem is that it takes 3 months to produce eco-enzyme, so it needs innovation to be able to produce it quickly. This research is an experimental study with independent variables, namely the composition of organic waste (rambutan fruit skin, corn cobs, chayote skin) as a substrate in varied eco-enzyme raw materials. Each treatment added 10% frangipani sandalwood extract. Control variables include fermentation time, water composition, brown sugar, yeast (Saccharomyches cerevisiae) with a fixed amount. The experimental results showed that the longer of fermentation time, the alcohol concentration increased, while the pH value decreased. The optimum time to produce eco-enzymes according to standard requirements for disinfecting purposes is 8-10 days, wherein the fermentation has produced an alcohol content of 60-70% and the pH of eco-enzymes has been reached below 4.0. The content of compounds in frangipani flower extract through phytochemical and GC-MS tests include terpenoids (linalool, geraniol, terpineol), quercetin from the flavonoid and citrulline groups of alkaloids and tannins which have various activities that support their role as a natural disinfectant including antibacterial, anti-fungi, and antivirals. The combination of Eco-Enzym from domestic organic waste and frangipani flower (Plumeria alba) is able to inhibit the growth of Staphylococcus aureus bacteria with very strong inhibition category ranging from 31.85-34.41 mm. Keywords: disinfectant, eco-enzyme, frangipani flowers

Abstract

Waste is unwanted residual material after the end of a process. The problem of waste has become a global issue that is a threat to the environment if it is not properly managed. Based on data from the Klungkung Regency Environmental Service in 2019, from four sub-districts in Klungkung Regency namely Dawan, Banjarangkan, Klungkung, and Nusa Penida, the volume of waste per day is more than 115,000 kg/person/day from a population of more than 230 thousand people, when compared production average waste production weighing 0.5 kg per person/day. Meanwhile, in terms of composition, the highest amount of waste is organic waste (68%), dust, rock and the like (8%), glass and plastic bottles 7%, followed by sheet plastic 5% and plastic 4%. The results of the analysis and depiction on the graph of the survey results were 4 (four) villages that had a high percentage of segregation, namely Semarapura Kauh Village (83.33%), followed by Semarapura Tengah (82.23%), followed by Semarapura Kangin Village (78.87. %) and Semarapura Kaja (75.21%). The results of this study prove that two locations have a very low level of sorting waste (less than 50%), namely Jempriring street in Semarapura Klod (47.61%), Rama street (42.11%), and Puputan street in Semarapura Kangin (44.73%). From this research, it can be concluded that public awareness of sorting waste in the two locations is still lacking.

Abstract

Biochar merupakan material yang kaya akan karbon dengan ciri fisik morfologi biochar berpori. Biochar memiliki kemampuan untuk menahan unsur hara dan air, meningkatkan kehidupan mikroba di dalam tanah dan secara keseluruhan meningkatkan kesuburan tanah. Kotoran hewan yang sering mencemari lingkungan dapat diubah menjadi biochar melalui pembakaran tidak sempurna untuk menghasilkan arang biochar yang dapat digunakan untuk memperbaiki tanah pertanian yang miskin unsur hara. Pengabdian ini dilaksanakan di kelompok tani ternak Satwa Winangun Desa Tangkas Kabupaten Klungkung yang berlangsung dari bulan Mei sampai Juli 2021. Kegiatan PKM ini bertujuan untuk meningkatkan pemahaman dan keterampilan mitra untuk berinovasi dalam mengolah limbah ternak menjadi biochar. Metode yang digunakan untuk mencapai tujuan tersebut adalah melalui pelatihan, pendampingan, dan alih teknologi dengan praktik langsung di lapangan. Alih teknologi pembuatan biochar dari kotoran hewan mendapat respon yang baik dari para peserta pelatihan, terutama karena mereka belum pernah membuat biochar. Melalui penguatan kelompok dan alih teknologi dengan program PKM, para peserta pelatihan telah dapat mempraktekkan secara langsung proses pembuatan biochar dan menghasilkan produk pupuk biochar yang siap diaplikasikan pada lahan pertanian.
