Abstract

Pengelolaan sawah tanpa masa istirahat serta tidak melakukan pergiliran tanaman menyebabkan berkurangnya bahan organik.  Bahan organik tanah sebagai penentu kesuburan tanah agar tanah mampu menyuplai unsur hara bagi tanaman. Pupuk organik dan bahan pembenah tanah (amelioran) merupakan kombinasi yang mampu meningkatkan bahan organik tanah dan menyediakan unsur hara. Biochar-kompos memerlukan perbandingan yang tepat pada tanah sawah yang telah lama digunakan hanya untuk tanaman padi tanpa input organik. Penelitian ini bertujuan untuk mempelajari efek sinergi penggunaan biochar dan kompos pada berbagai perbandingan terhadap pertumbuhan dan hasil tanaman kedelai (Glycine max L.) di tanah sawah setelah padi. Penelitian dilaksanakan pada bulan September sampai Desember 2022 di Dusun Bawang, Kelurahan Tunggul Wulung, Kecamatan Lowokwaru, Kota Malang. Penelitian menggunakan Rancangan Acak Kelompok (RAK) non faktorial terdiri atas 7 perlakuan dengan 3 ulangan yaitu K0 (tanpa biochar dan kompos), K1 (20% biochar dan 80% kompos), K2 (40% biochar dan 60% kompos), K3 (60% biochar dan 40% kompos), K4 (80% biochar dan 20% kompos), K5 (100% biochar) dan K6 (100% kompos). Persentase biochar dan kompos didasarkan atas penggunaan pada dosis sebanyak 500 g/polybag. Penggunaan 20% biochar dan 80% kompos menunjukan hasil panen yang paling tinggi yaitu 3,55 t/ha. Sebagian besar menunjukan korelasi positif dan hubungan kuat antara karbon organik, nitrogen, fosfor, dan kalium di dalam tanah dengan komponen hasil dan hasil kedelai.

Abstract

ABSTRAK Limbah pabrik berpotensi mencemari lingkungan. Adanya logam berat dalam tanah dapat diserap oleh tanaman yang dapat berdampak negatif bagi lingkungan dan makhluk hidup. Remediasi lahan perlu dilakukan, di antaranya menggunakan tanaman hiperakumulator hanjuang. Penelitian bertujuan mempelajari pengaruh remediasi lahan dengan tanaman hanjuang terhadap pertumbuhan tanaman padi fase vegetatif. Penelitian dilakukan bulan Maret-Agustus 2024 di Dusun Gampingan, Kecamatan Pagak, Kabupaten Malang. Penelitian menggunakan rancangan acak kelompok dengan delapan perlakuan dan tiga ulangan. Perlakuan terdiri dari: tanpa hiperakumulator tanpa bahan organik (HB1); tanpa hiperakumulator + pupuk kandang ayam (HB2); tanpa hiperakumulator + pupuk hijau Thitonia diversifolia (HB3); tanpa hiperakumulator + pupuk kompos  blotong tebu (HB4); tanaman hanjuang + tanpa bahan organik (HB5); tanaman hanjuang + pupuk kandang ayam (HB6); tanaman hanjuang + Thitonia diversifolia (HB7): tanaman hanjuang + blotong tebu (HB8). Data dianalisa menggunakan anova taraf 5% dan apabila terdapat pengaruh nyata dilanjutkan dengan uji beda nyata terkecil taraf 5%. Hasil penelitian menunjukkan bahwa perlakuan penanaman hiperakumulator hanjuang dan pemberian berbagai jenis bahan organik berpengaruh nyata terhadap pertumbuhan padi fase vegetatif yang meliputi tinggi tanaman, jumlah anakan dan total klorofil. Pada 56 HST perlakuan HB6 (hiperakumulator hanjuang + pupuk kandang ayam) memberikan jumlah anakan padi yang paling banyak (19.00) dibanding tanpa penanaman hiperakumulator hanjuang (14.33-14.50). Pada 30 HST perlakuan HB6 (24.02 mg/l) juga memiliki total klorofil yang paling banyak (32.71 mg/l) dibanding semua perlakuan lainnya (19.70-26.03). Semua perlakuan tidak mempengaruhi pH tanah.  ABSTRACTFactory waste has the potential to pollute the environment. The presence of heavy metals in the soil can be absorbed by plants that can have a negative impact on the environment and living creatures. Land remediation needs to be carried out, including using hanjuang hyperaccumulator plants. The research aims to study the effect of land remediation with hanjuang plants on the growth of rice plants in the vegetative phase. The research was conducted in March-August 2024 in Gampingan Hamlet, Pagak District, Malang Regency. The study used a randomized block design with eight treatments and three replications. Treatment consisted of: no hyperaccumulator without organic material (HB1); without hyperaccumulator + chicken manure (HB2); without hyperaccumulator + Thitonia diversifolia green manure (HB3); without hyperaccumulator + sugarcane filter cake compost (HB4); hanjuang plants + without organic matter (HB5); hanjuang plants + chicken manure (HB6); hanjuang plant + Thitonia diversifolia (HB7): hanjuang plant + sugar cane filter cake (HB8). Data were analyzed using anova at 5% level and if there was a real effect, it was continued with the least significant difference test at 5% level. The results of the research showed that the hanjuang hyperaccumulator planting treatment and the provision of various types of organic materials had a significant effect on rice growth in the vegetative phase which included plant height, number of tillers and total chlorophyll. At 56 HST the HB6 treatment (hanjuang hyperaccumulator + chicken manure) gave the highest number of rice tillers (19.00) compared to without hanjuang hyperaccumulator planting (14.33-14.50). At 30 HST the HB6 treatment (24.02 mg/l) also had the highest total chlorophyll (32.71 mg/l) compared to all other treatments (19.70-26.03). All treatments did not affect soil pH.

Abstract

Celery (Apium graveolens L.) is a leaf vegetable and medicinal plant usually used as a cooking spice. Several countries, including Japan, China, and Korea, use the leaf stalks as a food ingredient. The demand for celery continues to increase yearly, both domestically and abroad. Celery cultivation is rarely done in big cities because environmental conditions are unsuitable for growth requirements. Fertilization technology is one of the determinants in efforts to improve the quality and quantity of agricultural products. The use of appropriate fertilizer is expected to achieve economically profitable production levels. Fertilization essentially provides nutrients into the soil so plants' nutrient needs can be met. This research aims to determine the best use of organic fertilizer in increasing the growth and yield of celery plants. This research was conducted from June to September 2024 and is located in Tirto Rahayu, Rambaan Hamlet, Dau District, Malang Regency, East Java. This research used a Randomized Block Design with 7 treatments and 4 replications consisting of A1 (22 grams of urea), A2 (2.5 grams of humus), A3 (200 grams of goat manure), A4 (200 grams of chicken manure mixed with husks), A5 (2.5 grams of humus + 22 grams of urea), A6 (200 grams of goat manure + 22 grams of urea), and A7 (200 grams of chicken manure + 22 grams of urea). The research showed that A3 (200 grams of goat manure per plant) gave the best results, affecting plant height, number of leaves, wet weight, and volume of celery.

Abstract

The management of household waste, particularly organic waste, has emerged as a significant issue in RT 04 RW 06, Merjosari Village, Malang City. Over 50% of the total waste generated consists of organic materials. If not properly managed, organic waste can lead to environmental pollution and exacerbate health problems.This community service initiative aims to enhance public awareness and knowledge, especially among the local PKK mothers, regarding the management of organic waste through composting. The methods employed include site surveys, problem identification, coordination with relevant stakeholders, practical training on compost production, and demonstrations on using bioactivators to accelerate the composting process.The anticipated outcomes of this initiative include a reduction in the volume of unmanaged organic waste, improved soil fertility, and a decrease in negative environmental impacts. Through this training, it is hoped that the community will be better equipped to manage organic waste in a more effective and sustainable manner, ultimately fostering a cleaner and healthier environment.

Abstract

[CHLOROPHYL CONCENTRATION AND YIELD OF PAKCOY (Brassica rapa L.) AFTER TWO YEARS OF BIOCHAR AND ORGANIC FERTILIZER APPLICATION IN ENTISOLS]. While nitrogen is necessary throughout the growth of vegetable plants, N deficiency disrupts chlorophyll formation, and hence, affecting the photosynthesis process. This study aimed to study the impact of the use of biochar and organic fertilizers on chlorophyll content and yield of Pak coy mustard in the third planting season in Entisols. This research was conducted in Bawang Hamlet, Tunggulwulung Village, Malang City. The first and second planting seasons, were May-November 2017 and August 2018-January 2019, respectively. Research on the third planting season was carried out in July-August 2019 without nitrogen fertilization. The research was arranged in a randomized block design, consisting of controls (Kl), chicken manure (A), compost (K), rice husk biochar (S), rice husk biochar + chicken manure (SA), rice husk biochar + compost (SK). The results showed that after two years of application, biochar and organic fertilizers had a positive impact on the increase in yield of Pakcoy even though fertilizer was not provided. The application of biochar and compost provided the best residual effect on the total chlorophyll of Pakcoy mustard.
