Abstract

The  aim  of  this  experiment  was  to  analyse  chemical  composition  and  functional  properties  of  corn  starch  from various  corn  varieties  extracted  with  natrium  bicarbonat  solution.  Corn  kernels  of  N35,  Sticky  corn,  yellow  Srikandi  and yellow local varieties were processed into starch. The starch was extracted with 1% natrium bicarbonat solution (1:10 [w/v]).  Starch of commercial corn was used as a control. This experiment used Randomized Block Design with three replications. Results of this experiment indicated that the highest starch, amylose, fibre and free fatty acid contents were obtained at starch of yellow local variety; and the highest sugar, protein and lypide contents were found at yellow Srikandi variety, whilst the highest ash content was achieved at N35 variety. Starch of sticky  corn possessed the lowest amylose  content, but had the highest amylopectine content. The highest water absorbtion and solution rate were obtained at starch of yellow local variety.  Furthermore, the highest oil absorbtion rate was achieved at starch of sticky corn variety. Corn starch extracted with natrium bicarbonat solution had a lower quality compared to commercial corn starch, and therefore the corn starch recovered here apparently should not be recommended as a food source.

Abstract

Keberadaan kasus stunting dan pertumbuhan ekonomi yang lambat di Desa Binangga menjadi pendorong untuk melakukan pengabdian. Metode yang digunakan dalam menangani kasus melalui pendekatan barbasis produk daerah. Makanan fungsional dari tepung ampas kelapa dan daun kelor dapat digunakan untuk menangani stunting dan menumbuhkan ekonomi masyarakat. Penanganan stunting dan pemulihan ekonomi dilakukan melalui beberapa tahapan yaitu persiapan, produksi, standarisasi, penerapan, dan evaluasi. Tahapan persiapan meliputi indentifikasi dan diskusi masalah, serta sosialisasi dan penerapan pembentukan produk diikuti 45 orang yang terdiri dari ibu-ibu PKK, kader puskesmas, orang tua yang anaknya terindikasi stunting, dan petani kelapa. Dari identifikasi dan koordinasi dengan ibu-ibu PKK diperoleh data sekitar 10 anak yang terindikasi stunting berdasarkan jenis kelamin, usia, tinggi, dan berat badan anak. Tahapan selanjutnya dilakukan produksi dan standarisasi makanan fungsional. Tahapan penerapan dan evaluasi dilakukan dengan intervensi makanan fungsional selama 2 minggu dan pengukuran tinggi dan berat badan anak setiap minggu. Diperoleh hasil telah terjadi pertambahan tinggi dan berat badan anak rata-rata masing-masing 0,71 cm dan 0,48 kg tiap minggu. Keberhasilan intervensi makanan fungsional dalam meningkatkan tinggi dan berat badan anak dapat menjadi alternatif penanganan stunting. Keberhasilan ini juga dapat menjadi motivasi buat ibu-ibu PKK untuk mengembangkan dan memasarkan berbagai produk melalui platform digital.

Abstract

Pendahuluan: Koperasi Purun Al-Firdaus memiliki beberapa permasalahan diantaranya sumber daya manusia  bagian keuangan tidak mampu mengoperasikan komputer dan melakukan pencatatan operasional keuangan meliputi penjualan, pembelian, penerimaan dan pengeluaran kas dengan benar. Pencatatan transaksi masih dilakukan secara manual. Hal ini, menyebabkan sering terjadi kehilangan buku catatan penjualan dan pengeluaran kas sehingga berdampak pada proses pertanggungjawaban laporan keuangan bulanan yang menjadi terkendala. Proses pemasaran pun masih dilakukan secara tradisional menggunakan pamflet dan status aplikasi chat yang berdampak pada pangsa pasar kerajinan purun ini terbatas di Kalimantan saja.Tujuan: Pengabdian kepada masyarakat dilakukan dengan tujuan memberikan pelatihan kepada anggota koperasi yang mayoritas adalah ibu rumah tangga yang memiliki kemampuan dalam menghasilkan kerajinan purun supaya bisa menggunakan Web aplikasi keuangan SFIA (Smart Financial Application)  dan web promosi serta, memberikan pendampingan dalam mengkreasikan model kerajinan purun.Metode: Metode Pelaksanaan yang dilakukan dengan sistem Warrior Four Missing melalui metode Missing Based Learned yang akan dilakukan secara luring.Hasil: Menunjukkan bahwa terdapat para pengrajin yang mampu menggunakan Smart Financial Application (SFiA) untuk pencatatan transaksi dan pembuatan laporan keuangan serta pengetalasean produk untuk dipasarkan di dalam web SFiA. Simpulan: Kegiatan pengabdian kepada masyarakat untuk pengrajin Purun Al-Firdaus ini dilaksanakan dengan beberapa tahapan warrior four mission meliputi motivation class, Coaching Class, Creative Class dan The Day Intercamp yang telah dilaksanakan dengan baik dan di ikuti oleh banyak peserta PKM.

Abstract

Moringa seed oil is rich in oleic acid which has benefits for treating skin health. The use of Moringa seed oil as a basic ingredient for making transparent solid soap increases the advantages of soap because it has moisturizing and skin softening properties as well as antimicrobial. The manufacture of transparent solid soap based on Moringa seed oil aims to determine the mass of Moringa seed oil which produces solid soap with the highest foam and pH stability values, as well as the level of soap irritation. The study was conducted using a completely randomized design (CRD) with the independent variable being the mass of Moringa seed oil consisting of four levels of 27.5 grams (A1), 30 grams (A2), 32.5 grams (A3), and 35 grams (A4), while the dependent variables include foam stability and pH stability which were determined after 3 weeks of testing. The best formula was further tested with a solid soap irritation level test. The best formula for transparent solid soap was found in using 30 grams of Moringa seed oil (A2) with foam stability of 93.56%, pH stability of 9-9.6, and low irritation level of only 20% after five days of use.
