Abstract

Salah satu komoditas penting di Indonesia adalah kakao. Namun hanya isi biji yang dikelola secara komersial. Padahal limbah kulit kakao yang mencapai 95% dari total biomassa merupakan sumber bahan organik yang potensial. Namun, kulit kakao yang terdiri dari senyawa lignin, selulosa, dan hemiselulosa sangat sulit terdekomposisi. Jamur pelapuk merupakan salah satu jenis mikroba yang dapat mendegredasi senyawasenyawa tersebut. Penelitian ini bertujuan untuk mengetahui potensi jamur pelapuk untuk mendekomposisi limbah kulit kakao. Penelitian dilakukan dengan mengisolasi jamur pelapuk dari pertanaman kakao. Jamur pelapuk kemudian diinokulasi pada limbah kulit kakao. Dilakukan pengamatan penurunan bobot kakao dan uji lignoselulotik. Hasil penelitian menunjukkan isolasi jamur pelapuk menghasil isolat BSA, BPB, BPC, BPE1, BPE2, BSF, BPG, dan JT. Penurunan bobot limbah kakao tertinggi pada pemberian isolat BPB. Kadar selulosa terendah pada pemberian isolat BSA, sedangkan kadar hemiselulosa dan lignin terendah, masing-masing pada pemberian isolat BPE2 dan BPB.Kata Kunci: jamur pelapuk, lignoselulotik, kulit kakao

Abstract

Nickel mining decreases the quality of soil properties, it is not suitable for agriculture so alternative technology is required such us using biochar made from oil palm empty fruit bunch and mycorrhiza. This study aims to examine the effect of biochar made from oil palm empty fruit bunch and mycorrhiza to improve the nickel post-mining soil quality. This study used two-factor factorial randomized group design. The first factor is biochar made from oil palm empty fruit bunch with 4 levels; B0 (0 g), B1 (300 g), B2 (450 g), and B3 (600 g), the second factor is mycorrhiza with 4 levels; M0 (0 g), M1 (2 g), M2 (4 g), each treatment was repeated 3 treatments so that the total experiment was 36 units. The results showed that the use of bio-ameliorant waste from oil palm empty fruit bunch with dosage of 120 g / kg, improved the chemical properties of nickel post-mining soil regarding the parameter of C-organic, pH, available phosphorus, cation exchange capacity, exchangeable aluminum, Ca-dd and Mg -dd and increasing plant growth significantly. The treatment of mycorrhiza 0.4 g / kg significantly affected the soil properties regarding the parameters of root volume, root length and percentage of root infection and improvement of soil chemical properties in available phosphorus to plants and exchangeable aluminum parameters. The treatment of biochar with dosage of 120g / kg of soil and mycorrhiza 0.4 g / kg of soil is the best interaction of mycorrhiza and biochar made from oil palm empty fruit bunch as amelioration material of post-mining soil which is characterized by the decrease of exchangeable aluminum value. The application of biochar made from oil palm empty fruit bunch and mycorrhiza can improve the nickel post-mining soil quality

Abstract

Rice (Oryza sativa) production in Indonesia has declined due to low iron (Fe) availability in alkaline soils, impacting plant growth and yield. Integrating Fe seed coating with sago (Metroxylon sp.) waste organic fertilizer may improve Fe availability and soil quality, offering a potential solution to enhance rice production. Our objective was to examine the effects of Fe seed coating and the incubation of sage waste organic fertilizer on rice growth. The study employed a factorial 2-factor randomized block design. The first factor was the concentration of Fe seed coating, with four levels: 0 g, 55 g with 2.5 g gypsum, 110 g with 5 g gypsum, and 275 g with 12.5 g gypsum. The second factor was the incubation time of organic fertilizer, with four durations: 0 weeks, 3 weeks, 4 weeks, and 5 weeks. The interaction between Fe seed coating and sago waste organic fertilizer incubation significantly impacted plant height (153.33 cm), leaf color chart scale (4), chlorophyll a (254.73 μmol.m-2), chlorophyll b (96.90 μmol.m-2), with the most notable effects observed at a Fe seed coating concentration of 275 g with 12.5 g of gypsum and a 5-week incubation period. The application of Fe seed coating at a concentration of 275 g with 12.5 gypsum, combined with a 5-week of sago waste organic fertilizer, effectively enhances plant height, chlorophyll a, chlorophyll b, and the leaf color chart scales.

Abstract

This study aims to describe the linkage of carbon stocks in secondary forest and oil palm land cover to the amount of CO2 absorbed and the release of O2 to estimate carbon stocks in land cover in secondary forest and oil palm. The research use sample plot size 20 x 50 that taken 9 times for each land cover. Biomass data was collected using non-destructive sampling, since for undergrowth and necromass using destructive sampling by cutting and taking all the undergrowth and litter that are in a 1 x 1 meter quadrant. There are two kinds of soil sampling that collected; disturbed soil and intact soil. The results showed that the ability of each type of plant had varying values ​​of carbon stock, CO2 absorption and oxygen release on land cover. The value of carbon stock, CO2 absorption and oxygen release respectively on land cover, namely on secondary forest land cover is 265.86 tons / ha, 974.82 tons / ha and 708.96 tons / ha and oil palm is 100.89 tons / ha, 369.93 tons / ha and 269.04 tons / ha.

Abstract

Nitrogen use efficiency during the reproductive phase is critical for rice yield and grain quality. The rice-fish (minapadi) system that utilizes fish feed made from agricultural waste has the potential to enhance nitrogen availability through fish feces contribution. This study aimed to analyze the dynamics of nitrogen flow from soil to rice leaves and grains during the reproductive phase in a minapadi system. Four feed treatments were applied: no feed (N0), 5% Nitrogen (N1), 7% Nitrogen (N2), and 9% Nitrogen (N3). Nitrogen content was measured in soil, leaves, and grains during the primordia, flowering, and grain-filling stages. The results showed that N3 led to the highest nitrogen flow, with leaf N content reaching 3.1% and grain N content at 1.47%. This system demonstrates improved nutrient efficiency through the synergy between fish and rice, promoting sustainable agriculture based on local resources.
