Abstract

Degraded land affects almost all ecosystems and can harm the progress and quality of human life, so it needs attention. Saline soil is a land degradation with high salt content that causes toxic effects, increases root osmotic pressure, and inhibits plant growth. One solution is using organic mulch processed into biogeotextiles because it can provide solutions for erosion control and soil stabilization while minimizing negative impacts on the ecosystem. This research was conducted from May to August 2023 in the experimental garden of the Faculty of Agriculture UPN ‘Veteran’ East Java. This study used a group randomized design with one factor,  the type of geotextile material consisting of reed grass (RG), straw (ST), pandanus odorifer (PO), and sugarcane bagasse (SB). This research was conducted with a litterbox of 20x20 cm filled with 100 g of biogeotextile material. The results obtained show that pandanus odorifer biogeotextile material is the best biogeotextile material because it can last a long time on the soil surface, but can still be adequately mineralized, according to the results obtained, reducing the C/N ratio and C-Organic but increasing total nitrogen. Decomposition is closely related to the materials’ quality rather than external factors. The quality of the material, namely lignin, organic carbon, C/N ratio, and nitrogen, influences the decomposition process. Furthermore, this technology can be applied to improve soil productivity and to keep soil healthy.

Abstract

Pinang Jaya adalah Kelurahan di Bandar Lampung yang memproduksi sayur-mayur. Saat ini pemupukan sayur-mayur masing menggunakan pupuk kimia. Selain itu tingginya limbah rumah tangga yaitu nasi basi yang tidak termanfaatkan mengakibatkan terjadinya pencemaran lingkungan. Sehingga perlu dilakukan pengomposan limbah organik menjadi Mikroorganisme Lokal (MOL) in situ untuk mengurangi penumpukan limbah organik serta mampu menjadi pupuk organik cair. MOL limbah in situ dijadikan sebagai bahan pembenah tanah untuk mendukung sistem pertanian “Safe and Healthy Farm” dalam mewujudkan pertanian organik. Kegiatan pengabdian dilakukan dengan ceramah, demonstrasi, demoplot dan evalusi kegiatan. Sasaran dari kegiatan ini yaitu warga di Pinang Jaya dan anggota Safe and Healthy Farm. Berdasarkan hasil kegiatan pengabdian menunjukkan bahwa terjadi peningkatan pemahaman terkait pemanfaatan limbah organik berupa nasi basi in situ menjadi MOL sebesar 75%. Indikator penilaian pemahaman peserta pengabdian dinilai dari hasil pre-test dan post-test. Pada hasil pre-test pemahaman warga terkait MOL sangat rendah yaitu 20%. Setelah dilakukan penjelasan serta demontrasi pembuatan MOL, peserta pengabdian mengalami peningkatan pemahaman, hasil test setelah kegiatan yaitu 95%. Hal ini menunjukkan bahwa  warga Pinang Jaya telah memahami pengelolaan limbah rumah tangga menjadi produk MOL in situ.

Abstract

Kelurahan di Bandar Lampung yang memproduksi sayur-mayur salah satunya terdapat di Kelurahan Pinang Jaya. Penggunaan pupuk kimia saat ini masih diterapkan dalam budidaya sayur-mayur, hal ini mengakibatkan kualitas dan kuantitas sayur rendah. Selain itu, Kelurahan Pinang Jaya memiliki pabrik penggilingan padi yang limbah sekam padi belum termanfaatkan, sehingga menjadi sarang tikus yang menjadi hama tanaman sayur. Akibatnya terjadi penumpukan limbah sekam padi yang tidak dikelola dengan tepat, sehingga mencemari lingkungan sekitar. Solusi yang dimungkinkan yaitu pemanfaatan limbah sekam padi menjadi charcoal untuk mendukung sistem pertanian “Safe and Healthy Farm” dalam mewujudkan pertanian organik. Kegiatan pengabdian dilakukan dengan ceramah, demonstrasi, demoplot dan evalusi kegiatan. Sasaran dari kegiatan ini yaitu warga di Pinang Jaya dan anggota Safe and Healthy Farm. Berdasarkan hasil kegiatan pengabdian menunjukkan bahwa terjadi peningkatan pemahaman terkait pemanfaatan limbah sekam padi menjadi charcoal sebesar 75%. Indikator penilaian pemahaman peserta pengabdian dinilai dari hasil pre-test dan post-test. Pada hasil pre-test pemahaman warga terkait MOL sangat rendah yaitu 20%. Setelah dilakukan penjelasan serta demontrasi pembuatan charcoal, peserta pengabdian mengalami peningkatan pemahaman, hasil test setelah kegiatan yaitu 95%. Hal ini menunjukkan bahwa warga Pinang Jaya telah memahami pengelolaan limbah sekam padi  menjadi  charcoal.

Abstract

Methods of soil and water conservation in tropical wetlands have been carried out is using chemicals to increase the stability of soil aggregates and water-holding capacity. The experiment aims to improve soil stability using Polyacrylamide (PAM) and Super Absorbent Polymer (SAP) materials. Experiment was carried out in R&D Dept. PT. Great Giant Pineapple (PT. GGP), Lampung. The treatment was to mix ingredients into the water with variations the ratio of ingredients (g): water (ml), among others, 1:100, 1:200, 1:300, and 1:400. Next, the SAP/PAM material is mixed into 100 g of soil with a dose of 0 g, 4 g, 8.5 g and 10 g of SAP. After the soil was mixed with the SAP, take as much as 15 g and place it in a pot containing 1 kg of soil. Results experiment show the SAP is a polymer capable of increasing water availability in ultisols and sand used in the experiment and can increase the water content by 18% if compared control. Meanwhile, PAM is a more dominant polymer in its function as an aggregate adhesive instead of a water binder. Super Absorbent Polymer (SAP) and Polyacrylamide (PAM) can chemically function as chemicals for soil conservation.

Abstract

Acidic soil reactions, low nutrient content, low organic carbon levels, and low soil biodiversity characterize marginal land. Adding organic matter, such as compost, is expected to rehabilitate these lands. One key biological indicator of successful land rehabilitation by adding organic matter or compost is soil carbon microbial biomass (SCMB). This study aimed to assess the effect of compost on SCMB in pineapple plants. It was designed using a Randomized Completely Block Design with four treatments: Control (P0) = Without compost (Pineapple Cultivation Standard at GGPC), P1 = Cow dung compost (50 Mg ha-1), P2 = Premium compost A (50 Mg ha-1) and P3 = Premium compost B (50 Mg ha-1). Each treatment was replicated four times. The data were analyzed using ANOVA at the 5% significance level, following testing for homogeneity of variance using the Bartlett test and additivity with the Tukey test. Different treatment means were examined using contrast orthogonal tests, and correlation tests were performed to explore relationships among key variables. Results indicated that cow dung and premium compost (A and B) increased SCMB by 89.31% and 84.06%, respectively, at 15 and 16 MAP observations. At 16 MAP observations, soil organic carbon and soil pH were correlated with SCMB; in contrast, at observations 13, 14, and 15 MAP, soil organic carbon, soil pH, soil moisture, and soil temperature did not correlate with SCMB.

Abstract

The decline in pineapple production in Lampung Tengah regency occurred in 2023, where the decline reached 16.4% of the pineapple production in 2022 (8.6 million quintals). The decline in pineapple production came from PT Great Giant Pineapple (PT GGP), with the problem of accumulation of pineapple plant litter polymers on ultisol land. The solution that emerged was the adding of biochar, vermicompost and Azotobacter (LOB), with various plowing depth. The aim of this research was to determine the dynamics of Azotobacter population (log CFU g-1) in the ultisol soil of PT GGP’s pineapple plantations which were influenced by plowing depth, compost mixture and interaction between them. The supporting variables were the temperature (0C), water content (%), pH and soil organic carbon (%). Data analysis included ANOVA (α 5%), Tukey’s HSD Test (α 5%) and Pearson R Test (α 1%). The results showed that the Azotobacter population in pre-planting (PT) samples differed significantly between plowing depth, compost mixture and the interaction of the two factors. Deep plow treatment (± 40 cm) with finely chopped pineapple litter (L1) and application of premium GGP’s compost + LOB (P3) was the best treatment, with 4,96 log CFU g-1 Azotobacter population. Azotobacter population correlated not significantly with any supporting variables.
