Dewasa ini penggunaan lidah buaya sangat banyak digunakan dalam pembuatan produk kosmetik yang ramah lingkungan salah satu penggunaan lidah buaya pada pembuatan hair tonic yang berguna untuk melebatkan rambut. Lidah buaya memiliki kandungan utama seperti: minyak atsiri, gum, aloin, mineral, emodin dan vitamin. Lidah buaya yang dimanfaatkan pada penelitian ini adalah gel lidah buaya dari jenis lidah buaya barbadensis yang berarti tanaman yang kaya akan protein, vitamin A, C, dan E, kalsium, untuk melembabkan kulit, menghilangkan jerawat dan meremajakan kulit. Lidah buaya juga berfungsi sebagai antibakteri dan antiinflamasi. Kandungan kimia lidah buaya yang berupa gel dapat dipaparkan secara rinci yaitu saponin, asam sinamat, lignin, polisakarida, eteral oil, acemannan, vitamin B1, B2, B6, asam folat, tannin, enzim oksidase, amilase, monosakarida, glukomanan, enzim bradikinase, dan salisilat. Berdasarkan uraian diatas, maka dilakukan penelitian yang bertujuan untuk membuat hair tonic dari lidah buaya dengan kode F1, F2 dan F3 dengan masing ? masing perbandingan ekstrak lidah buaya dan cairan lidah buaya 1:1; 1:2; 1:3, untuk mengetahui sifat fisik dari ketiga hair tonic dan untuk melihat gugus fungsi yang terdapat dalam hair tonic dengan alat instrumentasi Fourier Transform Infrared (FTIR). Hasil penelitian yang diperoleh memperlihatkan bahwa Hair tonic F1 memiliki aroma khas lavender, warna peach, bentuk cairan kental, tekstur lembut, pH 3,8 dan viskositas sebesar 0,0039 ± 0,0003 NS/m2. Gugus fungsi yang terdapat dalam hair tonic F1 yaitu -(CH2)n, C=C aromatic, C=O amida, C=O ester, C-H alkana, C-H alkuna, C-H bending, alkuna dan O-H stretching.

ABSTRAK: Kulit pisang dan nasi merupakan limbah dari upacara keagamaan di Bali yang terbuang. Pembuatan bioetanol dilakukan untuk memanfaatkan limbah tersebut. Pada penelitian ini dilakukan pembuatan bioetanol campuran nasi dan kulit pisang. Campuran nasi dan kulit pisang yang digunakan dengan perbandingan 10:0; 7:3; 5:5; 3:7; dan 0:10. Tujuan dari penelitian ini adalah untuk menentukan kadar bioetanol yang diperoleh pada waktu fermentasi optimum. Penelitian ini dibagi menjadi beberapa tahap, yaitu tahapan persiapan sampel, hidrolisis nasi dan kulit pisang secara fisik dengan cara perebusan dan kimia dengan penambahan H2SO4, penentuan kadar gula pereduksi (Metode Nelson Semogyi), fermentasi, destilasi, dan penentuan kadar bioetanol menggunakan kromatografi gas. Kadar gula pereduksi tertinggi pada hidrolisis secara fisik (9,35%) dihasilkan dari campuran nasi dan kulit pisang (7:3) dengan waktu perebusan 50 menit, sedangkan kadar gula pereduksi tertinggi pada hidrolisis secara kimia (5,75%) dihasilkan dari campuran nasi dan kulit pisang (3:7) dengan konsentrasi H2SO4 1%. Waktu optimum yang diperlukan pada proses fermentasi campuran nasi dan kulit pisang pada hidrolisat secara fisik dan kimia menggunakan ragi tape berturut–turut 7 dan 6 hari, dengan kadar etanol masing–masing sebesar 4,17 dan 1,65%. Kata kunci: bioetanol, destilasi, fermentasi, gula pereduksi, hidrolisis, limbah kulit pisang dan nasi ABSTRACT: Banana peels and cooking rice are mostly becoming waste after Balinese religion ceremonies. Bioethanol production is carried out to utilize the waste. In this research, bioethanol mixture of cooking rice and banana peels is made. A mixture of cooking rice and banana peels used was with a ratio of 10:0; 7:3; 5:5; 3:7; and 0:10. The purpose of this research was to determine the content of bioethanol obtained at the optimum fermentation time. This research was divided into several stages, namely sample preparation stage, hydrolysis of cooking rice and banana peels physically by boiling and chemically with the addition of H2SO4, determination of reducing sugar content (Nelson Semogyi Method), fermentation, distillation, and determination of bioethanol content using Gas Chromatography. The highest reducing sugar content in physical hydrolysis (9,35%) was produced from a mixture of cooking rice and banana peels (7:3) with a boiling time of 50 minutes, while the highest reducing sugar content in chemical hydrolysis (5,75%) was produced from the mixture cooking rice and banana peels (3:7) with concentration H2SO4 1%. The optimum time required for the fermentation process on a hydrolyzate physically and chemically using yeast respectively 7 and 6 days, with ethanol content were respectively 4,17 and 1,65%.

The peel of banana kepok fruit (Musa paradisiaca Linn.) contains compound that function as an antioxidant in biodiesel. The purposes of this study were to determine the peroxide number, acid number, and FFA content of biodiesel from waste palm oil with addition of chloroform extract (EKKBPK). Biodiesel was synthesized using esterification reaction of wasted palm oil with methanol (10:1) and by transesterification reaction (4:1), the extract of peel of banana kepok fruit was theen added with various concentration of 0,1 % w/v (A1); 0,2 % w/v (A2); and 0,3 % w/v (A3) to the reaction mixtures. The peroxide number, acid number, and FFA content of synthesized biodiesel obtained in this research were 9.3591 meq peroxide/1000 g; 0.7221 mg KOH/g; and 0.33% repectively; biodiesel without addition of EKKBPK (12.2746 meq peroxide/1000 g; 0.6492 mg KOH/g; and 0.30%); and biodiesel with addition of EKKBPK 0.1 % w/v (11,1878 meq peroxide/1000 g; 0,4814 mg KOH/g; and 0.22%); 0.2 % w/v (9.7508 meq peroxide/1000 g; 0.3501 mg KOH/g; and 0.16%); and 0.3 % w/v (12.2512 meq peroxide/1000 g; 0.5217 mg KOH/g; and 0.24%). The acid numbers of those biodiesel were in acordance to the acid number of SNI 04-7182-2006. The addition of 0.2 % w/v EKKBPK on biodiesel showed the lowest peroxide number, acid number, and FFA content threfore it was the most effective in inhibiting the oxidation reaction of biodiesel.

Regression analysis was used to study the pattern of the relationship between the response variable and the predictor variable. There are two approaches used in this method, namely parametric and nonparametric. The most popular parametric regression used is multiple linear regression. In addition to parametric regression there are nonparametric regression approaches. One of the well-known nonparametric regression is Spline Truncated. This research to compare the multiple linear regression method with the Spline Truncated in the case of poverty in Papua Province. Based on the results of research on poverty cases in Papua Province, it can be concluded that the Spline Truncated regression is better than the multiple linear regression with R2 of 88.39%.

Mastery in literacy is an important indicator to improve the achievements of the younger generation in achieving success. One of the scopes of the Kampus Mengajar 2 Program is support for teachers in learning in all subjects, both from home and face-to-face at school, especially in literacy learning. Providing opportunities for students who have an interest in education to participate in teaching and deepen their knowledge by becoming teacher partners to innovate in literacy learning is one of the goals of the Kampus Mengajar 2 activities. The literacy learning innovation carried out by the Kampus Mengajar 2 Team at SD Negeri 15 Pemecutan is a literacy corner, telling stories together through fairy tales, folklore, legends and others, as well as conducting literacy simulations through the AKSI sekolah dasar program. These innovations can provide a new atmosphere for elementary school students so that they can improve students' literacy mastery, through a literacy culture from an early age.
