Abstract

The capturing process of CO2 directly from air has been developed largely considering with commercial scale in pilot plants. This is done so that the capture CO2 from air can be used as a feedstock or raw material for producing carbon free renewable fuels by applying direct air capture (DAC) process. This way of capturing is gone to be possible with using some solid & aqueous sorbents in pilot plant. The success of this capturing process is depended on the appropriate configurations of both major & minor plant operations. Heat & mass balance are required necessarily to contribute on the finding of each pilot plants data. The design of this process is modeled like this so that the captured CO2 can be delivered at 15MPa into the pilot plant & for this, the requirements of energy inputs are about 8.81GJ or 5.25GJ of natural gas & 0 KWHr or 336KWHr of electricity respectively. Then all the results finding from the pilot contactor, reactor, calciner are optimized to reduce the processing cost of the capturing process. It is observed after the ending of the process that the amount of operating cost is ranged between 50$ to 100$ to capture per ton of CO2 from surrounding air where the total levelized cost of the whole process ranges between 94$ to 232$/t-CO2. If it considers the other specific choices such as financial safety, environ mental & ecological arrangements etc. then this DAC process would be the best reliable solution to capture the CO2 from air in upcoming decades.

Abstract

The dynamic nature of forest habitats is currently influenced by the impact of many disturbing factors, including fire, grazing, area fragmentation, land use conversion and invasion of communities outside forest areas. Fire and smoke from forest and land fires have a profound effect in producing landscape changes that also affect the regeneration of associated vegetation and animals. This study aims to determine the participation of the members of the beekeeper group in preserving the Subanjeriji production forest, in Muara Enim Regency, South Sumatra Province. The research was conducted using a survey method with a qualitative approach. This study also aims to determine the attitudes, knowledge and perceptions of beekeepers on the relationship between beekeeping and forest suistanibility. The results showed that beekeepers known the suistanibility of forest areas that affect the success of beekeeping (80%), so that 60% of beekeepers understand very well that forest and land fires can reduce bee populations and reduce the amount of honey bee. Most breekeepers also understand that the existence of forest plants is very beneficial to support honey production, so that the majority beekeepers are involved in land enrichment efforts with woody plants and most choose Multi Purpose Tree Species (MPTS) plants that produce fruit. Keywords: Participation, Beekeepers, Beekeeping, Sustainibility, HP Subanjeriji

Abstract

Abstract: Previous studies have found four variant of swamp buffalo in the region of Pampangan based on the characteristics of habitats and morphology namely black buffalo, red,belang, and Lampung. Hence done observation to know the diversity and the kinship relation based on morphological characteristics. A method of on farm was done to data characterization and morphology. Data was analyzed using NTSys ver.2.1 and presented in dendrogram. Cluster analysis done with un-weighted pair-grup method with arithmetic averaging (UPGMA) with a coefficient similarities. The results show that morphology between variant buffalo that in eye color, the color of body, body size, or shapes and sizes horns. Buffalo belang having a dark eyes, the body white ribbed and light. Buffalo black having a black eyes and black body. Buffalo red having a red eyes, the body a red light colored (blonde). Buffalo Lampung allegedly is introduce from Lampung area, adapt and married with a local buffalo. The red buffalo having red eyes, like a black buffalo but shorter size with curved horns the way down. The results of the analysis kinship based on morphological characteristics show buffalo black and buffalo Lampung allegedly came from a single characterized by value a correlation coefficient of 0,85. Inbreeding and adaptation factors believed to cause different the phenotype and morphology. Buffalo  red having scarlet kinship the lowest is as much as 0,57 and predicted to have an ancestor different. Based on these results can be expressed variant swamp buffalo of regional Pampangan tending to low and the difference in the phenotype of influenced inbreeding and adaptation to the environmentKeywords: diversity, kinship, swamp buffalo (Bubalus bubalis), morphological characteristics, Pampangan South SumatraAbstrak : Berdasarkan karakteristik habitat dan pengamatan terhadap morfologi telah ditemukan empat varian kerbau rawa di wilayah Pampangan yaitu kerbau hitam, merah, belang, dan Lampung.  Untuk mengetahui keanekaragaman dan hubungan kekerabatan antar varian kerbau dilakukan penelitian ini. Pengamatam lapangan ditujukan untuk memperoleh data mengenai karakterisasi dan morfologi. Data dianalisis menggunakan NTSYS Ver.2.1 dan disajikan dalam bentuk dendrogram. Analisis kluster menggunakan metode Unweighted pair-grup method with arithmetic averaging (UPGMA) untuk mendapatkan koefisien similaritas. Hasil  menunjukkan perbedaan morfologi antar varian kerbau terlihat pada warna mata, warna tubuh, ukuran tubuh, serta bentuk dan ukuran tanduk.  Kerbau rawa belang memiliki mata gelap, tubuh bergaris putih dan ukuran tubuh kecil; kerbau hitam memiliki mata hitam dan warna kulit hitam;  kerbau mata merah memiliki mata berwarna tubuh lebih terang (warna bulu pirang); sedangkan kerbau Lampung diduga berasal dari daerah Lampung, yang beradaptasi dan kawin dengan kerbau lokal. Kerbau merah memiliki mata berwarna merah, memiliki tanduk yang lebih pendek dan melengkung ke bawah. Hasil analisis terhadap kekerabatan antar varian kerbau rawa diketahui bahwa kerbau hitam dan kerbau Lampung diperkirakan berasal dari satu induk dengan nilai koefisien korelasi sebesar 0,85. Inbreeding dan adaptasi diyakini menjadi faktor munculnya beberapa fenotip dan morfologi. Nilai kekerabatan terendah sebesar 0,57 ditemukan pada varian kerbau merah dan diperkirakan berasal dari nenek moyang berbeda. Berdasarkan hasil tersebut disimpulkan bahwa keragaman genetik dari kerbau rawa yang berasal dari daerah  Pampangan relatif rendah dan perbedaan fenotip lebih dipengaruhi oleh inbreeding dan adaptasi lingkungan.Kata kunci: keragaman, kekerabatan, kerbau rawa (Bubalus bubalis), karakteristik morfologi, Pampangan Sumatera Selatan

Abstract

Bukittinggi is one of city in West Sumatra that is potentially flooded and happen at the highest rainfall periods. Only three from 24 urban villages in Bukittinggi have low sanitation risk and it increases the flood-following disease. This research was done with quantitative approach to identified sanitation behavior among flood affected people as many as 47 respondents taken by proportional random sampling. The result showed the frequency distribution and percentage of each variable. Most flood-affected people in the Bukittinggi have toilets, but half of them use disposable diapers for their children and end up in trash cans. A small percentage of people dispose their waste water through toilets and their sewers are in poor condition. Most people do not segregate their solid waste and almost all of the solid waste have been dumped to the temporary dump site. Most people wash their hands with soap, but only small number do it before cooking. It is suggested to government to socialize the importance of sanitation and strengthen the role of community leaders to increase community awareness to have clean and healthy lifestyle.

Abstract

In the past ten years, public institutions including Kenyatta University have experienced a surge in population growth, exacerbated by a demand for higher education. The university population has increased eight times more between the year 2006-2016 leading to inadequacy in accommodation services within university premises, thus three quarters of these students reside in the neighboring areas. This study aimed at looking at the impact of this population increase on the water systems. Quantitative and qualitative methods were employed; three FGDs, key informant interviews and 220 respondents were interviewed comprising of; students, households, caretakers and small business owners. The study established that 62% of the residents used water from municipal water integrated to borehole supply. There were high water shortages marked with rationing as supply was only 2-3 times a week during student peak sessions. Most residents reverted to boreholes that were sunk without following set standards. 60% stored water in locally made tanks with low storage capacity inadequate to meet demand. The respondents felt the need to have an integrated holistic approach and coordination among all relevant stakeholders including; government, management institutions, households, students, public institution administrators, and businesses in order to comprehensively manage the water resources effectively

Abstract

Calculation and estimation of carbon stocks in various types of forests and ecosystems in Indonesia has been widely practiced. However, the availability of carbon stock information for some locations in the remaining forest area in South Sumatra Province is still very limited. This study aim to measuring the carbon storage potential and the ratio between the carbon storage value derived from the interpretation of satellite imagery and the storage of carbon stock from the field calculation. The method used is to calculate the estimation of carbon stock through satellite imagery interpretation and field measurement. The largest estimation of carbon stock through satellite image interpretation was found in secondary forest cover type with yield 896,234 ton/c/ha, followed by plantation land type with a yield of 147.104 ton/c/Ha and the smallest is open land cover with value yield of 2.883 tons/c/ha. While carbon stocks through field measurement yield 429,181 ton/c/ha of secondary forest cover type, followed by plantation land type with 41,169 ton/c/ha and 4,283 ton/c/ha for open land type. A comparison of carbon stock estimates of the two approaches used, yielding a reference value of 220%. These comparative values can be used to assist in carrying out initial estimates of carbon stocks in some types of land cover, especially for lowland forest types.

Abstract

Abstract: Candida tropicalis isolated from Tuak is a potentially useful microorganism for the ethanol production from lignocellulosic biomass and it can be alterbative agent replacing Saccharomyces cerevisae for fermentation process. Although C.tropicalis could not convert  all carbohydrates content of lignocellulosic into bioethanol, however it is able to grow on medium in the presence of either xylose or arabinose as carbon source.  Our result showed that fermentation of 10 % (w/v) cellulosic as sole carbon source produced 2.88% (v/v) ethanol by C.tropicalis.  This ethanol production was lower than usage of 10% (w/v) dextrose as sole carbon source  medium which producing 5.51% (v/v) ethanol.  Based upon our expreiment indicated that C.tropicalis is able to conduct two main process in converting of cellulosic material- to ethanol which is hydrolysis the degradation of cellulose into glucose, and fermentation the process the conversion glucose into bioethanol.Keywords  : Candida tropicalis, bioethanol, fermentation, cellulosic Abstrak (Indonesian): Candida tropicalis yang diisiolasi dari Tuak adalah agen yang berpotensi dalam produksi etanol dari biomasa lignoselulosa dan dapat dijadikan agen alternatif menggantikan Saccharomyces cerevisiae pada proses fernentasi.  Walaupun C.tropicalis tidak dapat mengkonversi semua kandungan karbohidrat lignoselulosamenjadi etanol, akan tetapi C.tropicalis mampu tumbuh pada media dengan xilosa atau arabinosa sebagaisumber karbon. Hasil kami menunjukkan bahwa dengan mengguankan C.tropicalis  fermentasi 10% (w/v) selulosa sebagai satu-satunya sumber karbon menghasilkan 2,88% (v/v) etanol, Produksi etanol ini lebih rendah jika menggunakan 10% (w/v) dekstrosa sebagai satu satunya sumber karbon yang menghasilkan 5,51% (v/v) etanol.  Berdasarkan percobaan menunjukkan bahwa C.tropicalis mampu melakukan dua proses utama dalam mengkonversi material selulosa menjadi etanol yaitu hidrolisis degradasi selulosa menjadi glukosa, dan fermentasi proses konversi glukosa menjadi bioetanol.Kata Kunci: Candida tropicalis, bioetanol, fermentasi, celulosik
