Abstract

Energi memiliki peran penting yang dapat dipisahkan dalam kehidupan manusia. Pemanfaatan energi yang tidak dapat diperbarui dapat menyebabkan masalah krisis energi. Baru-baru ini Salah satu masalah krisis energi adalah offset yang langka seperti minyak tanah, bensin dan solar. Saat ini Indonesia sedang menjajaki energi alternatif untuk menggantikan bahan bakar langka. Energi alternatif yang diamati dan dikembangkan di Indonesia adalah angin, air, matahari dan biomassa. Salah satu bahan bakar alternatif adalah dengan menggunakan biomassa yang dapat dibuat menjadi biobriket. Biobriket adalah salah satu bahan bakar alternatif yang aman digunakan oleh masyarakat dengan bentuk arang yang dibuat dengan kompensasi dan kekuatan tekanan tertentu. Salah satu biomassa yang dapat digunakan adalah kulit durian yang memiliki energi kalori tinggi dengan 6,274,9 kal / gr maka berpotensi dijadikan briket. Konstruksi biobriket dari kulit buah durian yang akan dibangun di Kasembon, Malang, Jawa Timur menggunakan sistem panas pirolisis lambat dengan 400celcius selama 6 tahun. Proses produksi Briket terdiri dari persiapan bahan, reaksi, pemisahan dan kemurnian serta penyerahan produk. Berdasarkan analisis ekonomi, perusahaan ini dapat dibangun secara normal dilihat dari aspek ekonomi dengan ROI: 83%, POT: 13 bulan, BEP: 41%, IRR: 36,80%. Kata-kata kunci : energi, biobriket, pirolisis ABSTRACT Energy has important role which cannot be separated in human's life. Utilizingenergy which cannot be renewed can cause the crisis problem of energy. Recently One of energy crisis problems is the rare offuelssuch as kerosene, gasoline and solar. Nowadays Indonesia is exploring alternative energy to replace the rare of fuels. The alternative energy being observed and developed in Indonesia are wind, water, sun and biomass. One of alternative fuels is by using biomass which can be made to be biobriquettes. Biobriquettes is one of alternative fuels which is safely used by society with the form of charcoal made by compensation and particular pressure power. One of biomass which can be used is durian rind which has high calor energy with 6.274,9 kal/gr then it can be potentially used as briquettes. Prabriquettes construction of durian rind which will be built in Kasembon, Malang, East Java uses pyrolysis slow heat system with 400celcius for 6 years. Process of Briquettes production consists of material preparation, reaction, separation and purity and product handing. Based on economy analysis, this company can be built normally seen by economic aspect with ROI :83%, POT :13 months, BEP :41%, IRR : 36,80%.

Abstract

Landslide problems often occur in Indonesia, such as in irrigation canals, most are still in the form of land channels, which results in considerable water loss due to many leaks, so that water disputes often occur by farmers during the dry season. The channel wall landslides also impacted the silting of the irrigation channels which resulted in a non-smooth flow of water, the need for irrigation water on the DI Channel. Lumbangsari (252 Ha) cannot meet the water needs in the rice fields. One of the ways used to control the stability of the soil so that it does not slide is to build a retaining wall on the channel. Planning the channel wall located in DI. Lumbangsari (252 Ha), Lumbangsari Village, Bululawang District, Malang Regency. In this evaluation plan, data is taken directly through direct surveys at locations and using maps of soil types. In order for the building to function properly, the stability of the building must also be planned as well as possible, therefore, the stability of the channel wall is analyzed with the danger of rolling (bolting) and gliding under normal water conditions without earthquakes, double earthquakes and flood water conditions without earthquakes , with earthquakes analyzed using Rankine formulas. The result is SFsliding 1.85> 1.5 and 1.85> 1.5, SFbolters 1.64> 1.5 and 1.64> 1.5 (for normal conditions without earthquakes and with earthquakes) and SFsliding 2.05 > 1.5 and 2.03> 1.5, SFbolters 1.67> 1.5 and 1.66> 1.5 (for flood conditions without and with earthquakes), the situation is safe. In this study the budget plan for the cost of the channel wall is Rp. 52,781,008.28.

Abstract

Roughness of the road is a system composed of several layers of material that is placed on the land-base (subgrade).Construction of elastic roughness (flexible pavement) consists of four layers, namely the surface layer (surface course), the upper layers of the Foundation (base course), a layer of Foundation bottom (subbase course), the basic soil Layer (subgrade).The main objective of the building of roughness is to provide a flat surface with skid resistance, with fairly long service lifespan, as well as minimum maintenance. To smooth the roughness is done.This road roughness along 1 km with an average width of 7,5 m in this study the author discusses the planning process calculation of thick layer (overlay) by using a method of analysis of the components of the Department of public works, based on the results of the calculation, obtained the order of thick layer (overlay) consists of the Foundation of the baw ah (Sub Base) 20 cm thick, Foundation top (Base Course) 15 cm thick, long layer surface (Surface) 5 cm. And obtained that the surface layer (overlay) approx 6 cm type of Asphalt Macadam with age plan 10 year and the growth rate of traffic gained 1% per year.

Abstract

Arang adalah suatu bahan padat berpori yang mengandung 80 - 90 % karbon yang dihasilkan dari pembakaran pada suhu tinggi (karbonisasi), sehingga bahan hanya terkarboninasi dan tidak teroksidasi menjadi karbondioksida. Penelitian ini bertujuan untuk mengetahui kondisi optimum pada proses karbonisasi dari sekam padi. Proses pengarangan dilakukan pada temperatur 400 oC, 500 oC dan 600 oC dengan variasi waktu 30 menit, 60 menit, 90 menit dan 120 menit. Kondisi optimum karbonisasi untuk sekam padi, yaitu pada suhu 400 oC selama 120 menit dengan kadar karbon terikat 41,3 %, kadar air 6,1 %, kadar abu 32,6 % dan kadar zat mudah menguap 20,5 %. Kata kunci : Arang, Karbonisasi, Sekam Padi ABSTRACT As agricultural countries, Indonesia has a great rice husk potential. One of alternative usage of rice husk isas a raw material for producing NSMC as fuel gas adsorbent. Production of NSMC consist of 2 stepsprocess, rice husk pyrolysis to produce and activated char with KOH. NSMC is nano structured porouscarbon as storage media for fuel gas. The aim of this experiments was studying the effect of pyrolysis timeupon char characteristic. The research was conductedin a fixed bed reactor equipped with condenser ininert condition. Pyrolysis conducted with time variation (30, 45, 60, 75 minutes). Pyrolysis reachedtemperature till 6000C. Char from pyrolysis process was analyzed with FTIR and BET methods. Thisresearch showed that char contained C-O functional group on absorbs range 1300-1000/cm. From BETmethods showed that char surface area was 8,91 m2/gram. It was concluded that optimum time of pyrolysisprocess was 75 minutes.

Abstract

Biochar fertilizer is a porous black charcoal produced by pyrolysis process with a relative temperature below 700 oC enriched with nitrogen (N). The benefits of biochar fertilizer are as a natural fertilizer (organic fertilizer) which is good for improving the condition of contaminated soil due to excessive use of chemical fertilizers and pesticides. Pecan shell waste has the potential to be used as a raw material in making biochar fertilizer by adding chicken manure which serves as a substitute for nitrogen elements that are lost in the candlenut biochar which is reduced or disappears during the pyrolysis process. The design of biochar fertilizer is planned to be established in 2021 in Dairi Regency, North Sumatra. Production capacity is planned to be 6,450.9320 tons / year with 9 hours / production, 300 days / year and in one day there are 2 processes. The process used is slow pyrolysis (slow pyrolysis) is one of the technologies used to convert hazelnut shell waste into charcoal (biochar). Based on economic analysis, the total investment in production is Rp. 15,924,053,007.45. Product sales value of Rp. 38,705,591,883 per year, with profit before and after tax is Rp. 9,978,936885 per year and Rp. 8,981,043,197 per year. The results of the feasibility analysis obtained ROI at (%): 64.86%, POT (Year): 1.4 Years, BEP (%): 32.333%, IRR (%): 20.296% So it can be concluded that the Pre-Design of Biochar Fertilizer with capacity of 6,450.9320 tons/year is worthy of being established.
