Abstrak. Mentimun (Cucumis sativus L) ialah salah satu tanaman dengan famili Cucurbitaceae (tanaman labu-labuan), mentimun banyak diminati oleh semua kalangan masyarakat. Dalam menjaga mutu mentimun setelah panen, penting untuk memperhatikan penanganan pasca panen agar mentimun tetap berkualitas ketika sampai di tangan konsumen. Salah satu metode yang dapat digunakan dalam penanganan pasca panen mentimun adalah dengan menggunakan pelapisan (coating). Pelapisan ini bertujuan untuk melindungi mentimun dari proses respirasi yang dapat merusak kualitasnya. Dengan melapisi kulit luar mentimun menggunakan lilin, respirasi dapat dikendalikan sehingga menghambat perubahan warna, menurunkan laju respirasi, serta meningkatkan penampilan kulit mentimun untuk menarik minat konsumen. Selain itu, pelapisan juga dapat memperpanjang umur simpan mentimun dan menjaga kesegarannya. Penelitian ini bertujuan untuk mengetahui efektivitas penambahan pati singkong pada edible coating gel lidah buaya terhadap kualitas mentimun dan pengaruh suhu penyimpanan terhadap kualitas mentimun. Percobaan ini dilaksanakan di Laboratorium Ilmu dan Teknologi Benih Jurusan Agroteknologi Fakultas Pertanian Universitas Syiah Kuala, Darussalam Banda Aceh pada bulan April 2022 sampai Juni 2022. Percobaan ini menggunakan Rancangan Acak Lengkap (RAL) pola faktorial 5 x 2 dengan 3 ulangan, sehingga terdapat 10 kombinasi perlakuan 30 unit percobaan. Setiap satuan percobaan terdiri dari 3 sampel mentimun. Terdapat dua faktor yang diteliti yaitu: Faktor pertama dalah penambahan pati singkong pada gel lidah buaya yang terdiri dari 5 taraf dan Faktor kedua yaitu perbedaan penyimpanan suhu yang terdiri dari 2 taraf. Berdasarkan hasil penelitian menyatakan bahwa penambahan pati singkong pada edible coating gel lidah buaya berpengaruh tidak nyata terhadap susut bobot, kadar air, kadar vitamin C. Hasil penelitian suhu penyimpanan menunjukkan pengaruh nyata terhadap kadar air hari ke 7, serta pengaruh tidak nyata pada susut bobot hari ke 7 dan kadar vitamin C hari ke 7.Abstract. Cucumber (Cucumis sativus L) is one of the plants belonging to the Cucurbitaceae family (gourd plant), which is in great demand by all levels of society. In order to maintain the quality of cucumbers after harvest, it is important to pay attention to post-harvest handling to ensure that the cucumbers remain in good condition when they reach the consumers. One method that can be utilized in the post-harvest handling of cucumbers is through the use of coating. The purpose of this coating is to protect the cucumbers from the respiratory process that can damage their quality. By applying a wax coating to the outer skin of the cucumbers, respiration can be controlled, thereby delaying color changes, reducing respiration rate, and enhancing the appearance of the cucumber skin to attract consumer interest. Furthermore, coating can also extend the shelf life of cucumbers and maintain their freshness.This study aims to determine the effectiveness of adding cassava starch to aloe vera gel edible coating on the quality of cucumbers and the effect of storage temperature on the quality of cucumbers.This research was conducted at the Laboratory of Seed Science and Technology, Department of Agrotechnology, Faculty of Agriculture, Syiah Kuala University, Darussalam Banda Aceh from April 2022 to June 2022. This study used a Completely Randomized Design (CRD) factorial pattern 5 x 2 with 3 replications, so there were 10 combinations treatment of 30 experimental units.Each experimental unit consisted of 3 cucumber samples. There are two factors studied, namely: The first factor is the addition of cassava starch to aloe vera gel which consists of 5 levels and the second factor is the difference in temperature storage which consists of 2 levels.The results showed that the addition of cassava starch to aloe vera gel edible coating had no significant effect on weight loss, moisture content, vitamin C content, L color (brightness), color a (red), color b (yellow), organoleptic test on outer color , deep color, texture, fragrance and overall acceptability.The results of the research on storage temperature had a very significant effect on weight loss, a significant effect on the moisture content on the 7th day, no significant effect on weight loss on day 7 and levels of vitamin C on day 7.

Media pembelajaran interaktif (MPI) merupakan komponen penting dalam meningkatkan pencapaian siswa sekaligus motivasi mereka. Dalam pembelajaran bahasa Inggris, reading menjadi topik yang cukup sulit untuk dipelajari. Ketersediaan teks yang panjang serta soal yang rumit membutuhkan bantuan media yang cukup efketif dan menarik, maka MPI adalah jawabannya. Untuk mengembangkan MPI, terdapat banyak alat yang bisa digunakan. Pilihan paling lumrah dan efisien adalah Microsoft Powerpoint (PPT). Guru dapat memanfaatkan PPT dalam pengembangan MPI asalkan mengetahui beragam fitur yang dibutuhkan. Di area Sumatera Selatan sendiri, yang mana masih ada wilayah-wilayah terbatas akan koneksi internet, PPT bisa diandalkan dalam hal media pembelajaran. Untuk itu, Ogan Komering Ulu Selatan (OKUS) menjadi target pendampingan tim Pengabdian Kepada Masyarakat FKIP Universitas Sriwijaya. Letaknya yang cukup sulit ditempuh dan sarana internetnya yang kurang stabil dapat dibantu dengan kehadiran MPI berbantuan PPT. Kegiatan dilaksanakan mulai dari September hingga Oktober 2024. Mode luring dan daring menjadi pilihan tim pelaksana. Secara bergantian, anggota tim menyampaikan materi-materi yang telah disusun. Lalu, di minggu ke-empat pendampingan, seluruh peserta diminta untuk mengembangkan MPI mereka sendiri yang nantinya akan digunakan di kelas. Keberhasilan pendampingan diukur melalui pre-test dan postest yang disebar secara digital. 25 orang guru yang berasal dari MGMP Bahasa Inggris OKU Selatan terdaftar sebagai peserta kegiatan ini. Pada akhir program, kedua puluh lima orang peserta ini berhasil mengembangkan media pembelajaran interaktif masing-masing dan mereka juga menunjukkan peningkatan pada beberapa elemen seperti pemahaman konsep MPI (52.6%), pemahaman fitur PPT (57.1%), integrasi audio/video ke dalam slide (71.4%), dan langkah-langkah pembuatan MPI (63.2%).

In education in Indonesia, there is a lack of effective examples provided by leadership in designing learning and implementing it in the field. The aim of this research is to analyze the influence of leadership on changes in secondary schools. The research method used was quantitative involving 562 secondary school teachers as respondents. The sample collection technique was carried out randomly. The data collection technique uses an instrument developed with a rating scale of 1 to 5 points. The data analysis technique is carried out using descriptive statistics with the help of SPSS version 25.0 to calculate the average value and analyze the relationship between variables. As a result, it was found that all dimensions of leadership were at a high category level. The mean showed that teachers' confidence in the implementation of their leadership as a whole was in the good category. These findings indicate that leadership wars make a significant contribution to changes in educational management for the better in secondary schools. The conclusion of this research is that application to leadership needs to be increased in schools and must be sustainable between new and old leaders. So that the effectiveness of learning can be maximized by teachers in junior high schools. The implications of this research indicate the need for training and development from leaders to teachers in junior high schools in improving the quality of planning management and implementation of learning.
