Ganoderma boninense is one of the main pathogenic fungus in oil palm plantations. Generally, these pathogen cause root rot (basal stem rot). Biological control that has been widely used reduce the infection is using bacteria. Liquid waste palm oil has potential to produce bacteria that is able to degrade Ganoderma boninense that causes root rot in oil palm. Liquid waste were obtained from Muaro Sabak Regency Jambi Province. Bacteri were isolated and cultivated in nutrient agar medium, characterized and identified for antagonistic test against G. boninense. Results showed that 16 bacterial isolates were identified, among of them are able to inhibit Ganoderma boninense.

Abstract. Hamzah A, Saputra R, Puspita F, Nasrul B, Irfandri, Depari NS. 2021. Ganoderma diversity from smallholder oil palm plantations in peatlands of Kampar District, Indonesia, based on mycelia morphology and somatic incompatibility. Biodiversitas 22: 16-22. Basal Stem Rot disease is caused by the pathogenic fungus Ganoderma boninense which has caused major economic losses in the palm oil industry. Ganoderma boninense has been reported not only infecting crops in the field, but also attacking at the immature phase of the plant even in the nursery. Studies related to Ganoderma diversity in oil palm plantations in Riau, Indonesia have not been widely reported. Ganoderma genetic diversity is important because its provide information regarding the mechanism of infection and the spatial distribution. The Ganoderma spp. isolates were collected from three blocks of smallholder oil palm plantation in Deli Makmur Village, Kampar District, Riau Province, Indonesia and brought to Plant Disease Laboratory, Faculty of Agriculture, Riau University, Pekanbaru, Indonesia. This experimental research was conducted using six Ganoderma isolates (Gan1, Gan2, Gan3, Gan4, Gan5, and Gan6) on the parameters of colony diameter and growth speed, while for the parameters of the morphological diversity of Ganoderma mycelium and the diversity based on somatic incompatibility assay was carried out descriptively. The results of this study show that oil palm plants in smallholder plantations in Kampar District are infected by two groups of Ganoderma based on morphology characteristics using UPGMA dendrogram, but different among isolates based on genetically using somatic incompatibility assay. For the next confirmation, it is necessary to further identify whether the six isolates are different species using molecular identification.

ABSTRAKEnergi  memiliki  peranan penting dalam proses pembangunan yang pada akhirnya untuk mencapai tujuan sosial,  ekonomi  dan  lingkungan  untuk  serta  merupakan  pendukung bagi kegiatan  ekonomi  nasional. Sumber energi terbarukan yang berasal dari pemanfaatan biogas limbah cair kelapa sawit dapat menghasilkan energi listrik yang saat ini banyak bergantung pada generator diesel dengan biaya yang mahal.Limbah cair kelapa sawit (Palm Oil Mill Effluent atau POME) adalah limbah cair yang berminyak dan tidak beracun, berasal dari proses pengolahan minyak kelapa sawit, namun limbah cair tersebut dapat menyebabkan bencana lingkungan apabila tidak dimanfaatkan dan dibuang di kolam terbuka karena akan melepaskan sejumlah besar gas metana dan gas berbahaya lainnya ke udara yang menyebabkan terjadinya emisi gas rumah kaca. Tingginya kandungan Chemical Oxygen Demand (COD) sebesar 50.000-70.000 mg/l dalam limbah cair kelapa sawit memberikan potensi untuk dapat di konversi menjadi listrik dengan menangkap biogas (gas metana) yang dihasilkan melalui serangkaian tahapan proses pemurnian. Di Kabupaten Kotawaringin Timur terdapat 36 Pabrik Pengolahan Kelapa Sawit yang total kapasitas pabriknya adalah sebesar 2.115 TBS/jam, menghasilkan limbah cair sebesar 1.269 ton limbah cari/jam dan mampu menghasilkan 42.300 m3 biogas.Kata kunci:  Renewable Energy, Plam Oil Mill Effluent, Chemical Oxygen Demand, Biogass, Methane. ABSTRACTEnergy has an important role in the development process and ultimately to achieve the objectives of social, economic and environment for as well as an environmental support for national economic activity. Renewable energy source derived from wastewater biogas utilization of oil palm can produce electrical energy which is currently heavily dependent on diesel generators at a cost that mahal.Limbah liquid palm oil (Palm Oil Mill Effluent, or POME) is the wastewater that is greasy and non-toxic, derived from the processing of palm oil, but the liquid waste could cause environmental disaster if not used and disposed of in open ponds because it will release large amounts of methane and other harmful gases into the air that cause greenhouse gas emissions. The high content of Chemical Oxygen Demand (COD) of 50000-70000 mg / l in the liquid waste palm oil provides the potential to be converted into electricity by capturing the biogas (methane gas) produced through a series of stages of the purification process. In East Kotawaringin there are 36 palm oil processing factory that total factory capacity is of 2,115 TBS / hour, producing 1,269 tons of liquid waste wastewater / h and is capable of producing 42,300 m3 of biogas.Keywords:  Renewable Energy, Plam Oil Mill Effluent, Chemical Oxygen Demand, Biogass, MethaneCara sitasi: Alkusma, Y.M., Hermawan, dan Hadiyanto.

<p>In the present study, microbiological quality of biscuits from street side bakery shops at Dehardun city, India was conducted. A total 11 samples of bakery biscuits were collected randomly and analysed for their microbiologically quality by standard plate count method. Pure cultures of bacterial isolates were prepared by streaking on nutrient agar medium. Bacterial isolates were further studied for morphological characters, culture characters on nutrient agar medium and biochemical testes in laboratory. All samples studies were found contaminated by a variety of bacteria. The highest bacterial load was 2.2 ×105 cfu/g and lowest was 0.1×103 cfu/g, respectively. Morphological observation, culture characters and results of biochemical tests of bacterial isolates were compared with standard results of known bacteria. The bacterial isolated were identified as Alcaligenes faecalis, Bacillus cereus, Micrococcus luteus, Pseudomonas aeruginosa, Streptococcus lactis and Staphylococcus aureus, respectively. Among these, two isolates i.e., A. faecalis and P. aeruginosa were gram negative and other isolates were gram positive bacteria which suggested the poor hygienic conditions inside the bakery during preparation and storage of biscuits. Gram positive bacteria might be contaminated during storage and by bad handling. These food spoiling bacteria might be responsible for food-borne infection and diseases. Therefore, care should be taken while purchasing such products and should be purchased from certified bakery shop.</p>

Palm oil is an export commodity of the plantation sector which began to develop rapidly in East Kalimantan with an area until 2017 reaching 1,192,342 Ha consisting of 284,523 Ha as plasma / smallholder plants, 14,402 Ha owned by SOEs as the core and 893,417 Ha owned by Large Private Plantation.Empty bunches (Tankos) are solid waste that is produced by palm oil mills in the process of managing palm fruit bunches into crude palm oil (CPO). In each processing 1 ton of fruit bunches will produce Tankos as much as 21-23%. Oil palm empty fruit bunches that are not managed properly will become waste that does not provide benefits. Compost technology using a local microorganism starter (MOL) can be used to produce quality organic fertilizer considering the process involves decomposing bacteria of organic ingredients. Compost technology from tankos waste is very possible to be developed, both at the level of farmers and private oil palm companies. This study aim to determine the potential of palm oil mill effluent (POME) as an bioactivator for composting oil palm empty fruit bunches, and to determine the chemical quality of oil palm empty fruit bunch compost with MOL bioactivator liquid waste as organic fertilizer. Through this research, it is expected that the palm oil mill's liquid waste can be utilized as a bioactivator for compost production and can be applied to the production of oil palm empty fruit bunch compost.This research was conducted for one year. The stages of the research are as follows: 1. Chemical analysis of POME waste, 2. Making LM POME, 3. Chemical analysis of LM POME, and 4. Making EFB Compost, and Chemical Analysis of oil palm empty fruit bunch compost. Compost making using randomized block design (RBD) with 5 treatments and 4 replications include: P0 = 0 ml / liter of water, P1 = 100 ml / liter of water, P2 = 300 ml / liter of water, P3 = 600 ml / liter of water, P4 = 900 ml / liter of water.The analysis showed that there was an increase in the chemical properties of POME after becoming an LM POME activator. Increased chemical properties such as phosphorus from 0.01 to 0.02, potassium from 0.19 to 0.27, and organic carbon from 0.90 to 1.30, but some chemical properties such as pH decreased from 7.20 to 3, 37 and nitrogen decreased from 0.37 to 0.05. The EFB compost analysis results showed that the highest pH was p2 with a value of 8.23, the highest organic C at p4 treatment with a value of 57.65, the highest total N at p3 with a value of 1.80, P2O5 the highest total at p3 with a value of 0.64, and the highest total K2O at p4 with a value of 2.68.

Palm oil is one of the plantation crops that have high economic value and is growing rapidly. The wider the area of oil palm plantations in Indonesia, the more palm oil mills will process palm fresh fruit marks and produce waste from processed palm oil, namely solid waste and liquid waste. Each tonne of fresh fruit bunches (FFB) processed at the plant will potentially leave waste of about 23% empty palm oil, 4% wet decanter solid, 6.5% shell, 13% fiber, and 50% liquid waste. This review will discuss the utilization of palm oil mill liquid waste (LCPKS) which is organic material that still contains many benefits such as nutrients, therefore the application of liquid waste is an effort to recycle some of the nutrients (recycling nutrients) which is followed by harvesting fresh fruit bunches (FFB) from oil palm so that it will reduce the cost of fertilization which is classified as very high for oil palm cultivation. During the processing of oil palm fruit into palm oil in the palm oil industry, the remaining process is obtained in the form of liquid waste. If done properly, the liquid waste of the palm oil industry is considerable potential and can increase the added value of waste itself.Keywords: liquid waste industry, palm oil, utilization
