Abstract

This study aimed to characterize the content of the leachate from lisimeter and assess the potential for leachate as liquid fertilizer. Leachate samples were taken from 5 lisimeter containing municipal waste in various sizes; A=(powder), B=(0.1 cm – 0.9 cm), C=(1.0 cm–1.9 cm), D=(2.0 cm – 2.9 cm), and E=(Original). Observation was conducted to leachate quality during bioconversion in 150 days. Result shows that at all treatment of degradation rates in leachate gives decreasing value of BOD, COD,NH4-N, TKN, and Phospate (P) except Kalium (K+) which increased during the bioconversion process. The value of TKN, Phospate, and Kalium (K+) is within safe limit to be dishcarged to the environment in the form of liquid fertilizer. Pollutant characteristics in leachate after anaerobic fermentation treatment in the form of heavy metals Hg, Cr, Cd. Pb, Zn, and Cu analyzed from all treatment shows values within safe limits to be discharged to environment in the form of liquid fertilizer. However, levels of BOD, COD and NH4-N are not yet qualified for discharge and require further treatment.Keywords: leachate, municipal waste, anaerobic fermentation, lysimeter

Abstract

Penelitian bertujuan untuk menganalisis karakteristik sampah kota dan produk-produk yang dihasilkan berupa biogas dan lindi. Eksperimen difokuskan pada kajian pra-perlakuan fisik terhadap bahan. Pengambilan sampel sampah dilakukan dengan cara grab sampling. Sampah organik hasil pemilahan dipotong-potong menggunakan mesin pemotong, kemudian diayak sesuai ukuran perlakuan dan selanjutnya dimasukkan dalam tabung bioreaktor. Bahan sampah terdiri dari lima ukuran: Slury (A), 1-3 cm (B), 4-5 cm (C), 6-7 cm (D), dan bentuk asli (E). Pengujian dilakukan terhadap beberapa parameter uji yaitu: Volume biogas diukur setiap hari dengan cara mengamati akumulasi peningkatan nilai volume pada gas holder yang dipasang pada bioreaktor selama proses bio-konversi; Produksi lindi ditampung dalam ember kemudian diukur volumenya dengan gelas ukur selama proses bio-konversi; Bulk Density dihitung menggunakan rumus bobot sampah organik dibagi volume sampah dalam tabung bioreaktor. Data yang diperoleh dianalisis secara deskriptif menggunakan tabel dan grafik. Hasil penelitian menunjukkan proses bio-konversi berbagai ukuran sampah kota dalam bioreaktor berbeda-beda pada masing-masing perlakuan. Perlakuan A (slury) mengandung kadar air terendah yaitu sebesar 72,47% sedangkan perlakuan E (ukuran asli) mengandung kadar air tertinggi 86,6%. Produk konversi yang dihasilkan berupa akumulasi volume biogas semakin tinggi apabila ukuran bahan sampah semakin kecil. Semakin besar ukuran bahan sampah menghasilkan produksi lindi semakin tinggi.

Abstract

In general, banana stem waste is rarely processed into liquid organic fertilizer (LOF) for plants. This study aims to determine the effect of banana stem LOF concentration on the growth of sugarcane cuttings using the Bud Chip method. Five treatments of banana stem LOF concentration were tested in this study, namely 0 ml/l solution (0%), 150 ml/l solution (15%), 300 ml/l solution (30%), 450 ml/l solution (45%), and 600 ml/l solution (60%). The experiment used a randomized block design with 5 replications. The data were analyzed by means of variance and continued with the comparison test of orthogonal and orthogonal polynomials at 5% significance level. The results showed that sugarcane cuttings given banana stem LOF produced better cuttings growth compared to sugarcane cuttings that were not given banana stem LOF, seen in the observation variables of shoot height, number of leaves, root length, shoot wet weight, shoot dry weight, root wet weight, and root dry weight. In the same observation variable, the concentration of banana stem LOF had a quadratic effect in which it initially increased the growth of sugarcane cuttings, until it reached the optimal concentration between 411.78 - 432.55 ml/l, then the growth of sugarcane cuttings decreased as the concentration of banana stem LOF increased.

Abstract

Endophytic fungi are types of microorganisms that live in healthy plant tissues without causing symptoms or damage to the host (Tayung & Jha, 2010; Aly et al., 2010). One of the most common endophytic fungi capable of acting as biological control agents is Trichoderma sp. Trichoderma sp. can suppress disease-causing pathogens in plants, especially soil-borne pathogens through mycoparasitism, competition and antibiosis mechanisms and can also directly stimulate plant growth and stimulate disease resistance responses (Widyastuti & Hariani, 2006; Soesanto et al., 2011). This study aims to identify Trichoderma sp. endophytic roots of rice plants to be used as biological control agents in tomato plants infected with Tobacco Mosaic Virus. This research was conducted at the Laboratory of Agrtochnology Satu Nusa Lampung University and PT Genetics Science Indonesia from September to December 2022. Endophytic Trichoderma sp isolates on rice plant roots that have been identified molecularly include Trichoderma asperellum species with analysis results. that the percentage of similarity is very high and the max score is above 700 and the e-value is 0.0.

Abstract

Potato is one of vegetables that has a lot of nutritional content. Potatoes contain the main source of carbohydrates, which are useful to increase energy and metabolic processes in the human’s body. This study aims to determine the response of potassium fertilizer (KCl) with different sizes of seed tuber on growth and production of potatoes. This research was conducted in three locations, namely the Horticultural Seed Center (BBIH) grounds, the Faculty of Basic Sciences Laboratory, and the Seed and Breeding of Plant Laboratory. The planting material used in this study was potato seed of the Granola G1 variety, the seed came from a potato seed producer in Lembang, West Java. This study used a factorial randomized block design (3x4). The factorial treatment consisted of two factors, the first factor was seed size (B) and the second factor was potassium fertilizer’s dose (K). Potassium fertilizer (KCl) and various sizes of seed tubers responded to the green level of leaves, plant height, wet weight of stover, amount of tubers, and tuber weight. The combination of potassium fertilizer (KCl) 30 kg ha-1 and large tuber size (±16.02 g) affected the growth and production of potato (Solanum tuberosum L.).

Abstract

Kabupaten Mesuji merupakan salah satu kabupaten yang berada di Provinsi Lampung, Indonesia. Salah satu desa yang memiliki luas lahan pertanian dan perkebunan yang cukup luas adalah Desa Kejadian, Kecamatan Way Serdang. Mayoritas pekerjaan masyarakat Desa Kejadian adalah petani dan peternak. Tanaman yang dibudidayakan meliputi sawit, karet, singkong dan padi. Peternakan hewan yang diusahakan yaitu kambing dan sapi. Berbagai masalah yang dihadapi petani di Desa Kejadian adalah maraknya pembelian pupuk palsu. Sehingga diperlukan sosialisasi cara membedakan pupuk asli dan palsu. Keberadaan pupuk palsu sangat merugikan petani dalam hal pertumbuhan tanaman. Harapan dari kegiatan ini supaya sosialisai cara membedakan pupuk palsu dan asli dapat dikembangkan ke berbagai wilayah di Kabupaten Mesuji dan daerah lain di Indonesia.
