Research of bioremediation of petroleum waste by indigenous petrophilic bacteria with biopile techniques at Klamono Area in Papua has been done. Petroleum waste was derived from various sources, namely tank cleaning, oil spills, oil catcher, leaking pipes, and drilling wastes containing oil residue. Preparation of petroleum waste has been done by adding wood sawdust as a bulking agent as much as 10% (w/w), the ratio of C: N: P: K = 100:5:1; 0.1 and mixed cultures of indigenous petrophilic bacterial isolated from the sources of the waste that has been collected in a storage-pit that Pseudomonas sp. (PSP01), Pseudomonas sp. (PSP05), and Bacillus sp. (PSP03) with 1:1:1 ratio of 0.5% (v/w). During the bioremediation process was aerated at a rate of 1 liter/jam/m3. Monitoring process have been done every week by doing the sampling with multiple sampling method to determine the five stations and each station has determined three sampling points,namelythe surface, middle and bottom based on the depth, samples have been obtained pooled and analyzed. The results showed that a decline in Total Petroleum Hydrocarbon (TPH) of 91.04% for six weeks. Total bacterial populations during bioremediation processes ranging 103 to 108 CFU/gram of soil. In addition at the end of the observation showed that the toxic aromatic compounds benzene, toluene, ethylbenzene, and xylene (BTEX) showed concentrations under the Environmental Quality Standards. Thus, indigenous petrophilic bacteria effective as biological agents in the bioremediation of petroleum waste by biopile method.

Prosiding Seminar Nasional Lahan Suboptimal ke-11 Tahun 2023, Palembang 21 oktober 2023 (pp.129-134) Palembang : Penerbit &Percetakan Universitas Sriwijaya (UNSRI).Sorghum plants have begun to be developed into a national food commodity in anticipation of climate change. It is necessary to know various basic agronomic information about sorghum, especially the growth and yield of ratoon so that a sustainable and profitable crop cultivation package can be prepared. This research aimed to assess the vegetative and generative potentital of the Bioguma 1 sorghum variety as ratoon. This research was conducted at the research garden, Faculty of Agriculture, Universitas Sriwijaya, Indralaya from February 2023 until August 2023. The methodology used was non-experimental. Sampling was carried out randomly for 80 plants from a population of 1600 plants. The research results showed that there was a decrease in vegetative and generative growth of ratoon sorghum compared to its parent. Decreases occurred in stem length (21%), number of leaves (50%), shoot dry weight (59%), panicle weight (61%), and number of seeds (22%). The decrease in generative components was greater than vegetative in ratoon sorghum plants.

Halimi, E.S., Zaidan, Z., Susilawati, S., Adriansyah, F., Cahyani, A.I., Panjaitan, M.S., Agustina, P., & Nuraini, H. (2023). Growth yield and segregation of several f3 generation of pepper accessions selected from the cross of curly and cayenne peppers. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-11 Tahun 2023, Palembang 21 Oktober 2023. (pp. 358-369). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Suboptimal land, in general, refers to condition of the land not prefectly suitable for cultivation, including those containing propagul caused disease infestation. On pepper cultivation, very often occurs disease infestation such as antracnose desease. Crossing curly and cayenne peppers was intended to obtain accessions of curly pepper having fruit position upward such as in cayenne pepper that capable of avoiding several diseases infestation. The F3-seeds were prepared 3 years prior to this research with selection to choose plant genotypes having fruit position upward. Research was done in-cooperation with farmer at Kecamatan Gunung Megang, Muaraenim on December 2022 to May 2023 based on Randomized Block Design with two accessions and three blocks with 10-15 plants per plot. Research indicated that both accessions showed good growth and yield with relatively similar harvesting period and yield potential. Interestingly, we observed several recombinat plants having fruit shape identical to curly peppers with fruit position upward. The plants of CK3(2)xCR3(6) accession, however had more slender fruit shape as compared to CK6(8)xCR6(4) accession. Furthermore observation indicated the presence of segregation of this character. Accession of CK3(2)xCR3(6) showed higher segregation value of 50% than CK6(8)xCR6(4) accession with segregation value of 25%.

Porang cultivation can be carried out using three planting materials, namely true seeds, bulbils, and cormel, these three planting materials experience dormancy. Potassium Nitrate Solution (KNO3) is a chemical compound that is effective in breaking the dormancy of some plant seeds.This study aims to the effect of shading, soaking with KNO3 and bulbil conditions on the emergence of shoots and the growth of porang plants. The research was conducted in September 2021 to November 2021. The design used was split split plot using three factors, shading (N) as the main plot, namely N0: without shade, N1: 45%, N2: 55%, N3: 80%, KNO3 concentration (K) as subplots, namely K0: Without immersion KNO3, K1: 1500 ppm, K2: 3000 ppm, K3: 4500 ppm and bulbil conditions (D) as sub-sub plots, namely D0: Dormant and D1: Mentis. The data collected included the percentage of shoots emergence, time of shoot emergence, broken petiole sheath, leaf open fully, shoot height, number of shoots, number of leaves, petiole length, petiole diameter, midrib length, leaf width, leaf area and leaf thickness. The results showed that shading 55% and bulbil mentis accelerated the emergence of shoot at 26 DAP and 26.9 DAP, respectively. Soaking in KNO3 solution did not accelerate the emergence of shoots. The emergence of shoots affects the time of petiole sheath break and the leaves open fully, the faster the emergence of shoot, the faster the petiole sheath breaks, the faster the leaves open fully. Shade 80% increases the growth of porang plants with the longest leaf petiole of 22.6 cm; petiole diameter 5.5 mm; midrib length 10.34 cm; the width of the leaflets is 4.7 cm and the leaf area is 183.2 cm², except for the thickness of the leaves.

Aglaonema commutatum or aglaonema is an ornamental leaf plant. In Indonesia, it is populary referred to as Sri Rejeki. Aglaonema variety Lady Gaga has high aesthetic value and demand by many people because its distinctive patterns and colors. The success of aglaonema cultivation is influenced by the composition of growing medium used. This study aims to determine the best planting medium composition through a comparative study. The research was conducted from July to September 2023 in Palembang City. Was arranged based on Randomized Block Design, consisting of three treatments: volcanic sand (M0), volcanic and rice husk 1:1 v/v (M1), and volcanic sand and risk husk 1:2 v/v (M2). The research data were analyzed using Analysis of Variance (ANOVA). The result of this study showed that the use volcanic and rice husk 1:1 v/v (M1) significantly enhanced all growth parameters, including the number of leaves, leaf length, leaf width, and new leaf growth; and parameters related to visual color and quality grade, namely parameters color, brightness, shape and size, also aglaonema leaf motif. In addition, direct sunlight also effect the color, brightness, and leaf motif of aglaonema var. Lady Gaga which is increasingly fading. Therefore, it is recommended that aglaonema cultivation be carried out in shaded areas that not exposed to direct sunlight.
