Buah terong adalah jenis sayuran yang sangat disukai oleh banyak orang , karena selain rasanya enak dan lezat untuk dijadikan sebagai bahan sayuran atau lalapan , buah terong juga mengandung banyak gizi yang cukup tinggi. Kandungan yang terdapat pada teong yaitu kandungan vitamin A sebesar 30,0 SI dan fosfor sebesar 37,0 mg per 100 g buah terong. Komoditas tanaman terong cukup potensial untuk dikembangkan sebagi penyumbang terhadap keanekaragaman bahan pangan dan juga sayuran bergizi bagi penduduk. Tujuan Penelitian ini adalah untuk mengetahui pengaruh aplikasi jenis pupuk organik padat terhadap karakteristik pertumbuhan dan produksi tanaman terung ungu (Solanum melongena L) varietas Reza. Pertumbuhan dan hasil produksi tanaman terong dipengaruhi oleh pemupukan. Pemupukan adalah pemberian pupuk terhadap tanaman dana alahan, dimana pupuk diberikan ke lahan sebagai sumber hara tanaman untuk memenuhi kebutuhan tanaman yang tidak mampu dicukupi oleh hara yang secara alamiah terdapat dalam tanah. eberapa jenis pupuk organik padat antara lain pupuk yang berasal dari bahan organik seperti kompos, bokashi, biochar, sedangkan pupuk organik padat yang berasal dari kotoran hewan antara lain pupuk kandang ayam, sapi, kasgot dan kascing. Tujuan Penelitian adalah Untuk mengetahui pengaruh aplikasi jenis pupuk organik padat terhadap karakteristik pertumbuhan dan produksi tanaman terung ungu (Solanum melongena L) varietas Mustang. Metode Penelitian menggunakan Rancangan Acak Kelompok (RAK) Non Faktorial dengan kombinasi diantaranya P1= Pupuk Kasgot ( 1,5 kg/plot ),P2     = Pupuk Kascing ( 1,5 kg/plot ), P3  = Pupuk Kandang Sapi ( 1,5 kg/plot ), P4= Pupuk Kandang Ayam ( 1,5 kg/plot ), P5= Biochar Sekam Padi ( 1,5 kg/plot ), P6= Biochar Sekam Padi + Pupuk Kasgot, P7= Biochar Sekam Padi + Pupuk Kascing, P= Biochar Sekam Padi + Pupuk Kandang Sapi, P9       = Biochar Sekam Padi + Pupuk Kandang Ayam, varietas Terung Ungu yang digunakan yaitu varietas Mustang. Hasil Penelitian menunjukkan Perlakuan pemberian pupuk organik padat berpengaruh tidak nyata terhadap tinggi tanaman, dan jumlah daun. Tinggi tanaman tertinggi terdapat pada perlakuan P1 (pupuk kasgot) sebesar 58.67 cm, dan jumlah daun tertinggi pada perlakuan P1 (pupuk kasgot) sebesar 10.22 helai, diameter batang tertinggi terdapat pada perlakuan P1 (Kasgot) yaitu sebesar 3.71 cm dan diameter batang terendah terdapat pada perlakuan P5 (biochar sekam padi) sebesar 3.52 cm

Spices are parts of plants that have a strong aroma and are used in small amounts in foods as flavours, preservatives, and food coloring. Spices are usually used as medicines, natural dyes, and spices. As a kitchen spice, spices have a variety of types, but have almost the same shape and color. In this study, the Machine Learning algorithm was tested which is one of the Artificial Neural Network methods that is often used to predict data. The research data used are export data of medicinal, aromatic and spice plants in 2012-2020. Based on this data, a network architecture model will be determined, including 3-10-1, 3-15-1, 3-20-1, 3-25-1. From the five models, training and testing were carried out first and then obtained the results that the best architectural model was 3-10-1 with 0.01929300. So it can be concluded that the model can be used to predict the export data of medicinal, aromatic and spice plants

Jeram Sanitary Landfill (JSL) receives waste from seven major municipalities, mostly from Kuala Lumpur and Selangor Municipality. The types of waste received are domestic waste, bulky waste and garden waste only. Currently, an average of 2100 tonne of solid waste per day from 470 compactors were landfilled daily at JSL. Each compactor disposed 4.6 tonnes which gives estimated at 766,500 tonnes in 2010. Out of this amount, 9.25 tonnes of Al end up in landfill per year. Most of the aluminum can are sent for recycling with approximately 1.39 tonnes/day. The leaching quantified through both gas and leachate was at 0.42 tonnes/day and 0.14 tonnes/day respectively. From the gas leaching, about 0.34 tonnes/day was released from the soil while 0.12 tonnes/day escaped through evaporation. Al in soil was quantified highest at near surface. This was identified as sink of the whole Al system. A major problem of sanitary landfill is the assessment of element transfers from inputs to outputs as a function of time due to the dynamic nature of the landfill activities.

Landfill can be an artificial carbon sink; accumulates and stores carbon-containing chemical compound for an indefinite period. Landfill posed risks of undesired environmental impacts due to the generation of leachate and gases namely carbon dioxide, CO 2 and methane, CH 4 with trace amounts of nonmethane organic compounds (NMOC) that include air pollutants and volatile organic compounds. Elements were selected based on environmental matrix and importance as raw materials with definite negative effects. In 2009, Jeram Sanitary Landfill received 730,547.79 metric tonne of waste from Kuala Lumpur and Selangor municipalities. Jeram Sanitary Landfill (JSL), as located in area of tropical country receives high amount of precipitation, about 1900mm to 2000mm, contributing to significant intrusion of acid deposition such as carbon monoxide, CO and nitrogen oxides, NOx. The quantity of leachate generated reflects the performance of landfill based on water balance components which include surface runoff, evapotranspiration, lateral drainage and leachate generated. Material Flow Analysis was realised using quantified possible inputs and outputs in elementary level. Kitchen waste and garden waste contributes significantly to the mass flow in landfill, indirectly contrubuting to source of organic carbon and total nitrogen in landfill. Carbon was predominantly exported in gas form whereas for nitrogen, the major pool was found in the atmosphere. The atmospheric pool of nitrogen was found coupled to the biogeochemical cycle, influenced by microbial nitrogen fixation and denitrification.

Abstract. Syaifudin M, Wijayanti M, Dwinanti SH, Muslim, Mahendra M, Marliana S. 2020. DNA barcodes and phylogenetic of striped snakehead and ocellated snakehead fish from South Sumatra, Indonesia. Biodiversitas 21: 1227-1235. This research aimed to identify the sequences of cytochrome c oxidase subunit I gene mitochondrial DNA (COI mtDNA), to construct a phylogenetic tree of striped snakehead (Channa striata) and ocellated snakehead (Channa pleuropthalma), and to measure water quality of Kelekar River, Indralaya, Ogan Ilir District and Danau Burung Besar River, Penukal Abab Lematang Ilir (PALI) District in South Sumatra, Indonesia. The research procedures consisted of DNA isolation, amplification by PCR (Polymerase Chain Reaction) and sequencing of fragment COI mtDNA. The length of nucleotide was 604 bp for striped snakehead and 587-604 bp for ocellated snakehead. Optimum annealing temperature was 500C for 15 seconds with 30 cycles. The result of BLAST analysis showed that striped snakehead from Kelekar and Danau Burung Besar River had 100% identity to striped snakehead from Java-Bali and furthest (97%) with striped snakehead from India. Ocellated snakehead had 100% similarity with the same species from Musi Banyuasin and Banjarmasin; and furthest (83%) with Channa limbata from Myanmar. Water quality in Kelekar River were temperature 31-31.60C, pH 4.76-4.96, dissolved oxygen 2.7-3.0 mg/L, ammonia <0.009 mg/L, total alkalinity 20 mg/L, and turbidity 62.5-63 cm. Meanwhile in Danau Burung Besar River showed temperature (29.3-30.70C), pH (3.6-6.7), dissolved oxygen (1.31-3.76 mg/L), ammonia (0.17-0.20 mg/L), and turbidity (50-90 cm).
