Abstract

The awareness of the negative impact of conventional farming and its safety have increased society’s perception of organic farming and its product. Unfortunately, the level of knowledge and adoption of organic farming practices among farmers are still low due to the assumption that organic farming is hard to implement. Ponorogo Organic Farming Community is a farming community that tries to adopt an organic farming system and has produced paddy and several horticultural crops cultivated organically. It was identified that the community had not yet applied the use of natural plant growth regulators (PGR) in their practice. Therefore, an agricultural extension activity was organized to share the knowledge on how to prepare an onion extract natural PGR. A survey was also performed to understand the level of knowledge and adoption of the participant. The questionnaire showed that most of the participants had not ever applied natural PGR even though had already heard about them before. Therefore, this program was of relevancy to improve the knowledge of the participant on organic way of farming particularly on the utilization of natural PGR.

Abstract

Purslane (Portulaca oleracea) is an underutilized plant that is commonly known as a weed; yet possesses high potential for its utilization as an alternative crop for medicinal purposes. This is due to Purslane's nutrient-rich status which, aside from its omega-3, is also a rich source of vitamins, minerals, and bioactive compounds such as phenolics and flavonoids. This work investigated the bioactive properties of Purslane extract in terms of Total Phenolics Content (TPC) and Total Flavonoid Content (TFC). The extract was prepared in ethyl acetate, ethanol, and n-hexane solvent using the maceration method. The results showed similar results in which the highest TPC and TFC were found in ethyl acetate extract at 14.74 ?g GAE/g and 11.56 ?g QE/g. This result showed the potential for further utilization of Purslane for medicinal purposes.

Abstract

Limbah kotoran ternak selaku produk samping budidaya peternakan mempunyai dampak negatif bagi lingkungan berupa bau, cemaran lingkungan, dan sumber penyakit. Biokonversi secara anaerob dapat mengonversi limbah kotoran ternak menghasilkan digestat akhir berbentuk slurry yang kaya kandungan hara sebagai pupuk organik. Sejauh ini, studi tentang dinamika sifat fisik dan kimia digestat dari berbagai jenis kotoran ternak masih jarang dilakukan. Penelitian ini bertujuan untuk mengkaji pengaruh tiga jenis kotoran ternak (kambing, ayam, dan sapi) terhadap sifat fisik dan kimia digestat. Percobaan dirancang menggunakan rancangan acak lengkap (RAL) sederhana dengan perlakuan tiga jenis kotoran dengan tiga kali ulangan. Digestat dibuat dengan bahan kotoran ternak, urin sapi, aktivator EM4, dan daun lamtoro yang diinkubasikan secara anaerob selama 14 hari. Parameter yang diamati meliputi aroma, warna, kekentalan, buih, pH, dan suhu yang diamati 2 hari sekali hingga 14 hari setelah inkubasi (HSI). Hasil menunjukkan bahwa digestat kambing dan sapi memiliki kesamaan pola dinamika sifat fisik dan kimia. Karakter aroma, warna, kekentalan, dan buih digestat sapi dan kambing cenderung tidak berubah selama masa inkubasi dibandingkan digestat ayam. pH ketiga digestat memiliki kecenderungan untuk turun di awal inkubasi dan naik di pertengahan hingga akhir inkubasi mendekati pH 7,0. Kenaikan suhu digestat ayam lebih tinggi mencapai 40 oC sementara kenaikan suhu digestat kambing dan sapi lebih rendah. Secara keseluruan, digestat kambing dan sapi cenderung lebih sulit didegradasi dan membutuhkan waktu lebih lama untuk terdekomposisi sempurna dibandingkan digestat ayam yang diduga dikarenakan perbedaan karakter kotoran yang dipengaruhi komposisi pakan, mikroba usus, dan struktur pencerbaan ternak tersebut.

Abstract

Microalgae are microorganisms with great potential as a superfood. Microalgae can serve as an alternative food source. One of their ecosystems is freshwater, where they can be cultivated on a small scale using indoor farming systems, especially in urban areas. This is because microalgae can live anywhere as long as their growth factors are fulfilled. This becomes a bright spot for agriculture in Indonesia, where land is becoming increasingly limited, causing millennial farmers to struggle with conventional cultivation. Therefore, indoor farming systems with IoT can become an alternative solution that supports food security and more effective microalgae cultivation. Microalgae are photosynthetic unicellular organisms influenced by several factors, including pH and light intensity. pH plays an important role in enzyme activity and nutrient availability, while light intensity affects biomass, cell density, and nutritional content. Both factors are crucial in determining biomass, cell density and protein content. However, studies on the combined effect of pH and light intensity on protein content in microalgae are still limited. Thus, this research aims to investigate the influence of pH and light intensity on protein content in an indoor farming system with IoT. The findings are expected to contribute valuable knowledge about optimal pH and light conditions for maximizing protein content in microalgae cultivation as a superfood. Then, according to the result, the combined interaction is 7 pH and 3000 lux light intensity is the optimal for cultivation of microalgae, which is much higher than other combines.
