“…Meanwhile, a preliminary study showed that the media concentration of 1/8 MS had the best effect on the number of pitchers, number of roots, percentage of live plantlets, percentage of plantlet's pitchers, and percentage of rooted plantlets in N. rafflesiana [26]. Another report on research results on the formation of pitchers in N. mirabilis and N. ampullaria, which are better on ¼ MS and ½ MS media [24]. Another study showed that the highest number of pitchers was found when N. ampullaria was cultured on an MS media without nitrogen [27].…”

“…The more deficient the nutrient content of the media, the more and larger the pitchers are likely to form [6]. Large pitchers formed on nutrient-poor media (1/16 MS) compared to the other nutrient-rich media [6,24].…”

“…Nevertheless, the pitchers were more significant on a media with more nutrient deficiency (1/4 MS and 1/8 MS) [23]. Another research reported that the number of pitchers formed was lower in N. mirabilis than in N. ampullaria and that the best media for forming pitchers was the 1/16 MS media [24]. This study aims to determine the effects of modified media on in vitro pitcher formation of N. ampullaria and N. rafflesiana.…”

Nepenthes, known as pitcher plants, is one of the unique ornamental plants that are highly sought after for their unique shape and color of the pitchers, a modification of the leaves. The pitcher was reportedly formed under nutrient-poor conditions at its growth site. This study aims to investigate the effects of modification of the culture media on the formation of in vitro pitchers of Nepenthes ampullaria and N. rafflesiana. The experimental design in this study used a completely randomized design with two factors (the species of Nepenthes and the media). Nepenthes ampullaria and N. rafflesiana plantlets with a stem height of about 1-2 cm were planted in medium containing half strength of Murashige and Skoog (1/2 MS), in medium containing sugar, agar, and distilled water (SAW), in medium containing agar and distilled water (AW) and medium containing sterile distilled water (W). All media were adjusted to a pH of about 5.7. The filter paper was used as a buffer in a liquid medium to support the plantlets. Each treatment was replicate three times, with each replicate containing ten bottles of culture, each containing one plantlet. Research results were observed for 12 weeks after planting and showed that all cultures could grow well in each medium. The highest average number of pitchers was recorded for the N. ampullaria culture planted in AW medium, with 22 pitchers/plant, followed by the culture in W medium, with 20 pitchers/plant. For N. rafflesiana, on the other hand, the highest number of pitchers was found in W medium with 18 pitchers/plant.

“…Dengan bahan baku sekam padi, temperatur pirolisis yang rendah (300 o C) memberikan hasil karbon yang rendah (49-70%) sedangkan pada temperatur tinggi (600 o C) memberikan hasil karbon mencapai 85-93% (Oni et al 2019). Pembakaran pembuatan biochar metode tungku bercerobong dari bahan kulit kopi membutuhkan waktu 1 hari (Hanisah et al 2020). Pembakaran untuk pembuatan arang secara tradisional menggunakan metode soil pit membutuhkan waktu 5-6 hari (Iskandar and Santoso 2005).…”

Biochar is a carbon-rich solid produced from the pyrolysis of biomass such as wood, manure, and leaves under high temperature and low oxygen conditions which is used for agricultural applications as a soil amendment. This paper reviews the utilization and practical application of biochar. The application of biochar into the soil can improve the physical, chemical and biological properties of the soil, namely increasing porosity, water holding capacity, soil aggregation, increasing pH, cation exchange capacity, soil organic carbon, nutrient retention and availability, and increasing microbial life, meso and soil macrofauna. Aside from being a soil amendment, biochar has a function on issues of global warming, climate change, and the environment, namely its role in carbon sequestration and stabilization, greenhouse gas emissions, and soil pollutant remediation. If biochar is applied properly, namely using the right feedstock materials, method of manufacture, dosage, method of application, and place, it will affect agronomic performance and crop yields. Reduced yields are mostly occured in temperate climates as biochar significantly increases soil pH causing an effect of excessive liming resulting in immobilization of key nutrients such as Mg, Fe, B, and P. Biochar needs to be mixed or applied together with fertilizer ingredients such as chemical fertilizers, bio-fertilizers, compost, and manure. Another effort is to enrich biochar with those materials so that biochar is categorized as a biochar-based fertilizer that has a higher selling price.

Biochar is a medium that is very suitable for soil. Making biochar itself is obtained from agricultural production waste. Utilization of agricultural waste is expected to produce new media that can increase agricultural production. This study aims to see how much influence the various types of biochar and type of biochar enrichment (NPK fertilizer and Plant Growth Promoting Rhizobacteria) on Pakcoy. The method used was factorial completely randomized design (CRD). Where the first factor is various types of biochar, namely from rice husks, coconut shells, oil palm fruit bunches, corn cobs and coffee fruit skins. The second factor is type of biochar enrichment (control, giving NPK and giving PGPR). The results obtained were the effect of biochar and the type of biochar enrichment had a significant effect on the parameter of the number of pakcoy plants. The results obtained were the effect of Biochar and type of biochar enrichment on the parameters of number of leaves to the pakcoy plant.
