Abstract

Along with the increasing number of people and all economic activities carried out, waste becomes acontamination that continues to leave problems. Sidoarjo Regency has 18 sub-districts with 350 villagesand a population of around 2.3 million people with a high level of economic growth. According to the 2017Sidoarjo Regency Environmental and Hygiene Office (DLHK), reported that Sidoarjo district residentsdispose of household waste around 0.5 kg per day. DLHK identifies the lack of Integrated WasteManagement Sites (TPST) and Final Waste Disposal Sites (TPAS) to accommodate and manage wastefrom the Sidoarjo Regency community. The lack of TPST and TPAS is not a problem in wastemanagement if active community involvement is involved in processing household waste known asCommunity Based Waste Management (PSBM). This abdimas method is a campaign about theimportance of the role of the community in improving environmental status and composting training withraw materials in the form of kitchen waste with a simple household-scale tool located in the KeteganVillage office, Tanggulangin Sub-district, Sidoarjo. The participants were very enthusiastic about takingpart in the training and were eager to practice household composting on a household scale for the need tofertilize plants planted in the yard. Participants want monitoring by the service team on the compostingresults that have been carried out by each participant.

Abstract

Botryococcus sp. is one of microalgae species that has a high lipid content as much as 75% of their dry weight. But, lipid production by microalgae is regulated by their environmental condition (pH, light, temperature, nutrition, etc). Mutagenesis induced by Gamma 60Co irradiation can be utilized to alter the Botryococcus sp. genetic to get microalgae mutant strain that can produce a higher lipid content than the wild strain. Botryococcus sp. was irradiated with different doses of gamma ray of 60Co (0, 2, 4, 6, and 10 Gy), and the effect on the growth, lipid content, and fatty acid composition of microalgae were observed. Research design used is random complete (RAL) with 95 % confident level for quantitive analysis based on the biomass and lipid contents. More over fatty acid composition was analyzed by Gas Cromatography-Mass Spectrometry (GC-MS). Results showed that Gamma irradiated gave an effect on growth and lipid content of Botryococcus sp. But between the control treatment (0 Gy) with microalgae irradiated dose of 2 Gy, 4 Gy and 6 Gy were not significantly different. Whereas between the control with 10 Gy irradiated was significantly different. The highest biomassa and lipid content are found in 10 Gy irradiated microalgae with 0.833 gram biomass and 41% lipid content. Fatty acid profile of Botryococcus sp. control has 6 fatty acids while 10 Gy irradiated microalgae has 12 fatty acids, with the long-chain fatty acids increased, whereas short-chain fatty acids decreased.

Abstract

Maize (Zea mays) is one of graminae plants that widely spread for many purposes wheter in food industry, feed, or bioenergy. Those high utilization required an increment in production, but unfortunately the needs were not meet to the demands since conversion of agricultural area increase lately. Indonesia has 99.093 km of shoreline that recognize as marginal land where the salinity is high as well. This research try to obtain tolerant variant from two local cultivars that planted in Madura Island. Manding and Talango varieties were used as an explant for callus induction stage in MS supplemented with 2.4 D. The result show that 4 ppm of 2.4 D were the best concentration to induce the callus in both varieties. The induced callus were exposed to medium MS that contain NaCl (0, 2500, 5000, and 7500 ppm). In 7500 ppm of NaCl, Manding variety has 100% of surviving callus, while Talango variety only 66.7%. Furthermore, Manding variety shows a better performance in callus weight improvement with 170 mg, while Talango shows no improvement of callus weight. The result of RAPD analysis indicate that the genome characteristic were different between initial callus and surviving callus. Out of ten primers, only five primers shows polymorphism i.e OPA 13, OPB 07, OPC 02, OPK 20, and OPU 19. Manding can be further developed as high tolerance variety in Salinity stress, thus it proposed to be developed furthermore.How to CiteSaputro, T. B., Finariyah, F., Dianawati, S., Sholihah, N.
