Abstract

This study is aimed to find out the composition, structure, and the ecological value of the types of trees in the exploitation zone of the National Wasur Park. The method used was square method, documentation, and literary study. Type variety index of Shannon-Wiener was employed to determine the variety types of the trees. The result of the research and data analysis showed that at the big tree category there were 16 types, 8 families, and 76 individuals. Meanwhile, at the small tree category, there were 12 types, 8 families, and 71 individuals. Analyzing the height structure, it was found out that Lophostemon lactifluus (F. Muell) Peter G. Wilson & J.T. Waterh (INP 54.74%) was the highest INP at the big tree category. Meanwhile, at the small tree category, the highest INP was Planchonia careya (F. Muell) R. Knuth (INP 68.82%). Therefore, the vegetation in the exploitation zone was considered as the Lophostemon lactifluus (F. Muell) Peter G. Wilson & J.T. Waterh and Planchonia careya (F. Muell) R. Knuth. The type variety index (H’) at the big tree and the small tree category were 2.43 and 2.9 respectively. These indexes were considered low. The ecological values of the forest were as the water diffusion area, system prop of life, and habitat of some animals such as various insect types, mammals and birds.

Abstract

Objective of the experiment to evaluate wheat growth of some plant density and the proportionof inorganic nitrogen and compost nitrogen.The research was conducted in the Sirapu Village, Semangga District, Merauke Regency using Randomized Complete Block Design with 3 blocks as replication. The first factor was plant density of three level, i.e., 25 cm x 10 cm, 25 cm x 15 cm, 25 cm x 20 cm.The second factor was proportion of inorganic nitrogen and compost nitrogen consists of six levels, i.e., compost 0% + urea 0%, 0% compost + 100% urea, 25% compost +75% urea, 50% compost + 50% urea, 75% compost + 25% urea, 100%compost + 0%.The experiment results showed that there was interaction between plant density and the proportion of inorganic nitrogen and compost nitrogen for plant dry weigh and crop growth rate parameters.Plant density in 25 cm x 15 cm and proportion of inorganic nitrogen and compost nitrogen in 25% compost +75% urea showed the best effect in plant dry weight and crop growth rate at 42 to 63 DAP.

Abstract

The purpose of the study was to determine the quality of the grainand rice are planted, the ricevarieties Inpago Unsoed 1. The research method use dis data collection, namely primary data andsecondary data. Primary data is used for observed in this research about grain moisturecontent,density of grain, foreign bodies, empty grains, grain crackedor broken, after the percentage ofgrain milled head of rice, broken rice, graing roats, grain limestone, yolk broken and milled rice yield.The results showed that during the observation the quality of grain varieties Inpago Unsoed 1 hasmilled at about 13,33% moisture content, grain density of 0,57g/ml, and grain weight is 27,60g/1000grain. The percentage point for the determination quality of head point is 73,49%, broken grainsabout 13,92%, and 12,34% graing roats. The quality of rice milled varieties inpago Unsoed 1 includelow. The lower of rice quality is due to the low of head rice percentage, while the percentage ofbroken grain sand high graing roats. Rice milled yield about 51,23%

Abstract

The purpose of this research is to design the auxiliary blower that can be used to overcome theblockage on the bran expenditure correct and to know the speed of the blower. The method of thisresearch consisted of the first step (literature study, proposal masking, equipment and material supplyand design the auxiliary blower tool), the second stage is the making of bran blower auxiliary tool, andthird step is the test (measuring wind speed in the blower using anemometer, comparing the level ofcleanliness of rice from rice bran, and recapitulation of tool making). The results obtained in the fieldconditions 3.5-inch pulley of 16.6 m/s has a moderate wind speed so that groats are not much wasted.The percentage of whole rice after using the blower on the second observation that is using the 2.5-inch pulley of 98.12%, the third using 3.5-inch pulleys of 97.56%, the fourth using 4.5-inch pulleys of95.70% and treatment before using blower 89.59%. Based on the recapitulation of the tool making, thetotal cost of making the tool are Rp.2.505.500.

Abstract

The availability of complete land resource data and information is needed to support sustainable agricultural development programs. The purpose of this study was to determine the level of land suitability as well as the limiting factors for rice, corn and shallots in the newly opened land of Bokem Village, Merauke District. Soil samples taken from the field were analyzed in the laboratory. Parameters observed were soil texture, C-organic, N-total, P2O5, K2O, CEC, and DHL. Data analysis was carried out by matching or comparing land requirements for plants and land properties in the study area. The results of this comparison show the level of land suitability for corn, soybeans and peanuts which include S1 (very suitable), S2 (appropriate), S3 (marginally suitable), N1 (currently not suitable) and N2 (permanently inappropriate). The results showed that the land suitability class for lowland rice was classified as marginal suitability class (S3) with limiting factors for nutrient retention (f) and available nutrients (n). For corn plants belonging to the current suitability class are not suitable (N1) with limiting factors for nutrient retention (f) and available nutrients (n), while for shallot plants (S3) with limiting factors for water availability (w) nutrient retention (f) and available nutrients (n). Basically the existing limiting factors can be corrected by fertilizing and liming.

Abstract

Luasnya lahan sawah tadah hujan di Kabupaten Merauke membuat tingginya potensi waktu panen pada saat musim hujan. Peningkatan kualitas hasil panen padi dapat dilakukan melalui pengolahan pasca panen seperti pengeringan dan penyimpanan yang benar. Tujuan dari penelitian ini adalah untuk merancangbangun dan melakukan uji kinerja alat pengering biji-bijian sistem bed dryer dengan tungku pemanas tak langsung. Pembuatan alat pengering biji-bijian sistem bed dryer dengan kapasitas menengah dapat membantu petani lokal untuk memperbaiki kualitas hasil produksi panennya. Metode penelitian menggunakan metode rekayasa melalui beberapa tahap yaitu perancangan alat pengering, rancangan fungsional, rancangan struktural, dan uji kinerja. Alat pengering biji-bijin sistem bed dryer memiliki dimensi bak penampung 240 cm x 360 cm x 120 cm dengan daya tampung 2000 kg; diameter kipas 60 cm; temperatur maksimal ruang angin/ruang bertekanan 70°C; kecepatan angin maksimal tanpa gabah 10 m/s sedangkan dengan gabah 7 m/s; daya motor penggerak dinamo single phase 3 kW; volume pemakaian bahan bahan bakar (kayu) sebanyak 1,1 m3. Lama waktu pengeringan berkisar pada 20 jam, dengan kadar air akhir gabah mencapai 12,2 %. Teknologi tungku pemanas sistem tak langsung yang berfungsi sebagai sumber panas dari alat pengering ini mempunyai peran yang sangat penting terhadap kualitas hasil pengeringan, lama waktu pengeringan serta pengoperasionalannya bernilai ekonomis dibandingkan dengan tungku pemanas konvensional lainnya.

Abstract

Tepung sagu yang diproduksi oleh industri pengolahan tepung sagu”Dwitrap” belum memenuhi SNI untuk standar kehalusan yakni lolos ayakan 100 mesh minimal 95% sesuai dengan SNI 01-3729-2008. Tujuan penelitian adalah menghasilkan mesin pengayak pati sagu dengan penggerak motor listrik untuk meningkatkan kualitas mutu tepung sagu pada industri pengolahan tepung sagu “Dwitrap”. Penelitian ini menggunakan metode eksperimen dengan membuat dan melakukan uji coba alat pengayak pati sagu. Bahan pati yang digunakan yaitu pati sagu Dwitrap. Perhitungan yang dilakukan adalah perhitungan kecepatan pulley dan kapasitas alat sedangkan pengujian pengayakan dilakukan dengan mengayak pati sagu sebanyak 10 kg yang diulang sebanyak 3 kali. Ukuran ayakan yang digunakan adalah 100 mesh. Berdasarkan hasil pengayakan akan diperoleh pati sagu yang lolos dan tidak lolos ayakan. Selain itu, dilakukan juga perhitungan kadar air pati sagu sebelum pengayakan. Penelitian ini menghasilkan suatu alat pengayak pati sagu dengan penggerak motor listrik 1 hp dengan spesifikasi panjang 210 cm, lebar 74 cm dan tinggi 94 cm. Alat ini terdiri dari 4 komponen utama yaitu rangka, corong pengeluaran, pengayakan dan motor listrik. Uji kerja alat dilakukan dengan perhitungan dan analisis. Sampel yang digunakan adalah 10 kg pati sagu dengan waktu yang digunakan 1 menit, hasil penelitian menunjukan bahwa selama pengayakan, pati sagu yang lolos ayakan sebanyak 505,64 kg/jam dengan kadar air 11,16 %.
