EVALUASI KEKRITISAN LAHAN DI KAWASAN LINDUNG KECAMATAN PUJON KABUPATEN MALANG JAWA TIMUR DENGAN TEKNOLOGI SISTEM INFORMASI GEOGRAFISCriticality evaluation of land in protected areas in Pujon, Malang, East Java With Geographic Information System TechnologyTatag MuttaqinJurusan Kehutanan, Fakultas Pertanian dan Peternakan, Universitas Muhammadiyah MalangJl. Raya Tlogomas No 246 MalangEmail: tatag.umm@gmail.comABSTRACTPujon is upstream of Brantas river basin situated in the northern part of Malang. Pujon at this time has been impaired, such as conversion of forest land into agricultural land and settlements do not observing requirements for soil and water conservation which hydrologically a catchment area for the district of Malang. Land-use rules do not pay attention to soil and water conservation in Pujon potentially cause degradation that will ultimately lead to degraded lands. It can be seen from the continuing impact of the critical area, namely the problem of flash floods and erosion in watersheds Konto Sub Das Brantas. Based on the description in the above background has been known problem as follows: a) how the condition of critical land in Pujon, b) how the land use right direction according to the land capability region. This study was conducted in Pujon Malang starting in August 2014 s / d in July 2015. The method used is overlaid on the techniques of spatial analysis. Spatial analysis is a technique or process that involves a number of counts and evaluation logic (mathematical) were performed in order to seek or find (potential) relationship (relationship) or patterns (probably) are among the elements of geographical (contained in digital data with the boundaries of the study area). The survey results revealed that, the area Pujon the classification of criticality otherwise not critical area of ??2768.52 or 21.71%, somewhat critical area of 3755.44 or 29.45%, a critical area of 4584.50 or 35.95%, potentially critical area of 939.37 or 7:37% and very critical area of 705.97 or 5:54 %.Keyword: Critical land, erosionABSTRAKKecamatan Pujon merupakan hulu dari DAS Brantas terletak di bagian utara Kabupaten Malang. Kecamatan Pujon pada saat ini telah mengalami gangguan, berupa alih fungsi lahan hutan menjadi lahan pertanian dan permukiman yang tidak memperhatikan syarat-syarat konservasi tanah dan air yang mana secara hidrologis merupakan daerah resapan untuk wilayah Kabupaten Malang. Pemanfaatan lahan yang tidak memperhatikan kaidah-kaidah konservasi tanah dan air di Kecamatan Pujon berpotensi menyebabkan terjadinya degradasi lahan yang pada akhirnya akan menimbulkan lahan kritis. Hal ini dapat dilihat dari dampak lanjutan dari adanya lahan kritis yaitu permasalahan banjir bandang dan erosi di aliran sungai Konto Sub Das Brantas. Berdasarkan uraian dalam latar belakang di atas telah diketahui permasalahan sebagai berikut: a) bagaimana kondisi lahan kritis di Kecamatan Pujon, b) bagaimana arahan penggunaan lahan yang tepat sesuai dengan kemampuan lahan kawasannya. Penelitian ini dilaksanakan di Kecamatan Pujon Kabupaten Malang mulai bulan Agustus 2014 s/d Juli 2015. Metode yang digunakan adalah teknik overlay pada analisis spasial. Analisis spasial adalah suatu teknik atau proses yang melibatkan sejumlah hitungan dan evaluasi logika (matematis) yang dilakukan dalam rangka mencari atau menemukan (potensi) hubungan (relationship) atau pola-pola yang (mungkin) terdapat di antara unsur-unsur geografis (yang terkandung dalam data digital dengan batas-batas wilayah studi). Hasil penelitian diketahui bahwa, kawasan di kecamatan pujon yang klasifikasi kekritisannya dinyatakan tidak kritis seluas 2768.52 atau 21.71%, agak kritis seluas 3755.44 atau 29.45%, kritis seluas 4584.50 atau 35.95%, potensial kritis seluas 939.37 atau 7.37% dan sangat kritis seluas 705.97 atau 5.54%.Kata kunci : Lahan Kritis, erosi

Abstract

Daun sambiloto mengandung senyawa andrographolid. Senyawa ini dapat berfungsi sebagai hepatoprotektor karena andrographolid merupakan derivat flavanoid yang dapat berperan sebagai antioksidan.  bersifat toksik yang dapat mengahsilkan radikal bebas. Radikal bebas secara alami penting karena berkaitan dengan immunitas, pertumbuhan dan perbaikan. Namun radikal bebas yang berlebihan juga mempunyai efek negatif karena merusak protein, lemak dan asam nukleat, sehingga kemudian radikal bebas dapat merusak sel-sel hati. Penelitian ini bertujuan untuk mengetahui pengaruh dosis dekok daun sambiloto terhadap kadar SGPT dan SGOT tikus putih yang diinduksi  serta untuk mengetahui dosis dekok daun sambiloto yang efektif untuk menormalkan kadar SGPT dan SGOT tikus putih yang diinduksi . Hasil penelitian menunjukkan bahwa ada pengaruh pemberian dekok daun sambiloto terhadap kadar SGPT tikus putih yang diinduksi  (F hit = 6217.678). pemberian dekok daun sambiloto juga berpengaruh terhadap kadar SGOT tikus putih yang diinduksi  (F hit = 1396.704). perlakuan  dapat meningkatkan kadar SGPT tikus putih hingga 20 kali dan kadar SGOT hingga 16 kali. Dosis sambiloto 50% dapat menurunkan kadar SGPT dan SGOT mendekati normal.

Abstract

TAsphalt concrete mix is one type of flexible pavement layer. Asphalt concrete mixture consistsessentially of coarse aggregate, fine aggregate, filler and binder. Aggregate used may be natural orthe result of processing and can also be the artificial aggregate. While grading for asphalt concretemix is Continuously graded. This study aimed to assess the absolute density, ie density of a pavementlayer maximum value. Absolute density is needed in order to predict the quality of road pavementlayers in accordance with the variation of the number of collisions 2x75, 2x150, 2x200, 2x300 and2x400 blows. Then studied the effect of variations in the collision of the Marshall test parameters,which include density, stability, voids of mineral aggregate (VMA), voids filled with asphalt (VFWA),voids in the mix (VITM), flow and marshall qoutient. The results showed a variation of the effect ofcollisions on the value of VITM. specially for heavy traffic comparison of values obtained onvariation of the collision VITM 2x150, 2x200, 2x300 and 2x400 to VITM standard is between 50-60% (collision 2x75). These results indicate that all kinds of variations of the collision above thestandard collision will result in fatigue of materials, pavement materials become damaged as aresult. From the results of this study also obtained the optimum asphalt content for heavy traffic,moderate and mild, respectively, are 6.44%, 6.59% and 6.86%. From the results of this study alsoobtained a density value of the field whose value is based on the optimum asphalt content in successionto heavy traffic, medium and light, which is 2.35 g / cc, 2.35 g / cc and 2.36 gr/cc

The application of HHO gas injection regardless of the uncontrolled burning can degrade the quality. In this research, design and manufacture of Dry Cell Elektrolyzer system and testing the characteristics of electrolysis HHO gas.  This tool uses only pure distilled water medium is inserted into the tube available. In addition, NaOH or KOH is also used as an ingredient. The addition of HHO gas on combustion engines to improve the quality of combustion because gas has a calorific value and high octane.  Current setting is done via Pulse Width Modulation (PWM) to vary the gas production. Gas production can be setup became active at rpm above idle and the gas flow rate can be varied based on the spin machine.Keywords: Elektrolyzer, Electrolysis, Dry Cell, HHO Gas ProductionABSTRAKGas HHO adalah hasil dari elektrolisis air yang telah digunakan sebagai campuran bahan bakar dalam mesin pembakaran. Penerapan injeksi gas HHO terlepas dari pembakaran yang tidak terkontrol dapat menurunkan kualitas.
