EVALUASI pH DAN ALUMINIUM (AL+) DALAM TANAH DI KAMPUNG ERAMBU DISTRIK SOTA KABUPATEN MERAUKE

Soil plays an important role in agriculture, soil cannot be separated from soil fertility in order to obtain maximum results. Soil quality on soil fertility is determined by the interaction of a number of physical, chemical and biological soil properties. pH, c-organic, and Al are some of the quality factors of soil fertility. Evaluation of pH, c-organic, and Al content aims to find out the current conditions and what solutions must be made. The research method was carried out by taking disturbed soil samples on primary, secondary, residential, and grassland lands, then carried out soil laboratory analysis. The results showed that: actual and potential soil pH is highest on residential land. The actual pH is 7.61 and the potential is 6.75 and is classified as neutral. While the actual pH in secondary forest, primary forest, and grasslands, the soil pH ranges from 4.42-4.99 which is classified as acid and the potential pH is 3.81-4.19 and is classified as very acidic. Meanwhile, the Al+ content was relatively low for each land use, namely 1.81-5.76 cmol/kg.Tanah sangat berperan penting dalam bidang pertanian, tanah tidak lepas hubungannya dengan kesuburan tanah agar didapatkan hasil panen yang maksimal. Mutu tanah pada kesuburan tanah ditentukan oleh interaksi sejumlah sifat fisika, kimia dan biologi tanah. pH, c-organik, dan Al merupakan beberapa faktor kualitas kesuburan tanah. Evaluasi kandungan pH, c-organik, dan Al bertujuan untuk mengetahui kondisi terkini dan solusi apa yang harus dilakukan. Metode penelitian dilakukan dengan pengambilan sampel tanah secara terganggu pada lahan hutan primer, sekunder, pemukiman, dan lahan padang rumput, selanjutnya dilakukan analisis laboratorium tanah. Hasil penelitian menunjukan bahwa: pH tanah aktual maupun potensial tertinggi berada di lahan pemukiman. pH aktual sebesar 7.61 dan potensial sebesar 6.75 dan tergolong netral. Sedangkan pH aktual di hutan sekunder, hutan primer, dan padang rumput pH tanah sekitar 4.42-4.99 tergolong masam dan pH potensial mencapai 3.81-4.19 dan tergolong sangat masam. Sedangkan kandungan Al+ tergolong rendah disetiap penggunaan lahan sebesar 1.81-5.76 cmol/kg

PENGARUH KETEBALAN IRISAN KERUPUK SAGU TERHADAP WAKTU PENGERINGAN DAN DAYA KEMBANG KERUPUK

This study aimed to determine the effect of the thickness of the sago cracker slices on the drying time and the ability to swell the crackers in the frying process. The research was started by making sago cracker dough and then sliced ​​with a thickness of 3 mm, 5 mm, and 7 mm. Each slice was then dried in the sun for 27 hours (3 days). The sampling of cracker chips was measured for water content at the 9th hour, 18th hour, and 27th hour. Cracker chips are fried to test their ability to swell. The results showed that the drying time for the thickness of the 3 mm sago cracker slices was the fastest compared to the 5 mm and 7 mm thickness of the sago cracker slices. The thickness of the 3 mm sago cracker slices also has the highest ability to swell compared to the 5 mm and 7 mm thicknesses of the sago cracker slices.Tujuan penelitian ini untuk mengetahui pengaruh ketebalan irisan kerupuk sagu terhadap waktu pengeringan dan daya kembang kerupuk  pada proses penggorengan. Penelitian diawali dengan membuat adonan kerupuk sagu kemudian diiris dengan ketebalan 3 mm, 5 mm, dan 7 mm. Masing-masing irisan kemudian dikeringkan dengan sinar matahari selama 27 jam (3 hari). Pengambilan sampel chips kerupuk diukur kadar airnya pada jam ke-9, jam ke-18, dan jam ke-27. Chips kerupuk digoreng untuk diuji daya kembangnya. Hasil penelitian menunjukan bahwa waktu pengeringan ketebalan irisan kerupuk sagu 3 mm paling cepat dibanding ketebalan irisan kerupuk sagu 5 mm dan 7 mm. Ketebalan irisan kerupuk sagu 3 mm juga memiliki daya kembang paling tinggi dibandingkan dengan ketebalan irisan kerupuk sagu 5 mm dan 7 mm
