Abstract

Tebu (Saccharum officinarum) merupakan salah satu bahan penghasil gula utama di Indonesia dan memiliki peran penting dalam perekonomian Indonesia dan menjadi sumber devisa negara.  Kemenperin mencatat, produksi gula nasional hanya mencapai angka 2,17 juta ton. Sementara, kebutuhan gula nasional mencapai 66 juta ton. Ini menandakan Indonesia baru mampu memenuhi 3,29% dari total kebutuhan nasional, sehingga lebih dari 96% defisit kebutuhan gula nasional yang belum mampu dan harus dipenuhi Indonesia.. Tujuan dari penelitian ini adalah mendapatkan komposisi media kultur yang tepat dan optimal untuk pertumbuhan akar dari kalus embriogenik tanaman tebu. Penelitian ini bertempat di Laboraturium Kultur Jaringan Politeknik Negeri Lampung. Proses induksi akar ini dilakukan melalui modifikasi media MS dengan campuran IAA, Kinetin, CM, 2,4-D, dan sukrosa yang dilakukan dengan Rancangan Acak Kelompok. Variabel yang diamati adalah respons kalus, waktu tumbuh akar, panjang akar dan jumlah akar. Hasil penelitian dan pengujian menunjukkan bahwa komposisi media berpengaruh terhadap perkembangan akar. Media dengan  kombinasi IAA menghasilkan respons berupa akar, namun media dengan kombinasi 2,4-D memberikan respons berupa pelebaran kalus. Hasil pengamatan menunjukkan perlakuan terbaik untuk pengakaran adalah kombinasi media IAA 1 mg.l-1 baik berupa rata-rata panjang 1,56 cm dan jumlah akar 2,08.

Abstract

Sugarcane (Saccharum officinarum L.) is a plant that is cultivated to be processed into sugar. However, until now Indonesia has become a sugar importing country because the sugar industry is unable to meet the needs and demand for sugar which continues to increase as well as the high domestic selling price, so that it is necessary to import sugar to meet the demand for sugar in Indonesia. To overcome this is to apply Nitrogen fertilization on sugarcane combined with a companion material in the form of Zeolite. This study aims to obtain the growth and yield of ratoon 2 sugarcane plants by administering Zeolite and the proportion of N fertilizer as well as the interaction between the Zeolite and the proportion of N fertilizer. This study used a Randomized Block Design (RAK) Arranged in a split plot with two treatment factors repeated 3 times with 6 treatment combinations to obtain 18 experimental units. The main plot of Zeolite dosing with Z₀ is without zeolite and Z₁ is 700 kg.ha⁻¹ (equivalent to 0.8 kg.8m kairan⁻¹). Subplot dosage proportions of N fertilizer with P₁ is 100% urea (equivalent to 0.36 kg. 8m caustic⁻¹), P₂ is 80% urea (equivalent to 0.28 kg. 8m caustic⁻¹), and P₃ is 60% urea (equivalent to 0.21 kg. 8m caustic⁻¹). The results of this study indicate that the dose of Zeolite has an effect on all variable parameters of growth observations which include plant height, stem diameter, and number of internodes. As well as plant yields which include stem weight, stem length, brix value and yield. Application of [dose percentage of N fertilizer did not affect the growth and yield of sugarcane plants. There was no interaction between the Zeolite dosage and the proportion of N fertilizer doses on the growth and yield of sugarcane

Abstract

Coffee is a widely enjoyed beverage in Indonesia and around the world, holding a significant role as a key commodity in Indonesia's plantation sector. This beverage is popular not only for its distinctive flavor but also for its various health benefits. This article reviews several main bioactive components in coffee, including caffeine, chlorogenic acid, ferulic acid, and caffeic acid, as well as the potential health benefits of each. Caffeine is known as a stimulant that can enhance alertness, reduce drowsiness, and acts as a potential antioxidant. Chlorogenic acid functions as an anti-inflammatory, antihypertensive, antidiabetic, and anti-obesity agent, helping to reduce the risk of cardiovascular diseases. Ferulic acid has strong antioxidant effects and is used as a diabetes therapy due to its ability to reduce oxidative stress, while caffeic acid is known for its anticancer, antioxidant, and antibacterial activities, supporting the prevention of atherosclerosis and cardiovascular diseases. This article also discusses the mechanisms of action for each bioactive component within the body, particularly on the nervous system, lipid metabolism, and antioxidant activity. Through this review, coffee is understood not only as a refreshing beverage but also as a potential agent in the therapy and prevention of various chronic diseases.

Abstract

Stevia can be developed by vegetative and generative propagation, while the generative propagation of stevia can be done through seeds. Conventional provision of seeds or seedlings has a low success rate. Propagation via tissue culture is faster, produces more seeds, and is identical to the parent, so the plants’ quality is expected. Plant growth regulator (PGR) often used for tissue culture is type auxins, cytokinins and gibberellins. The function of auxin and cytokinin for division cells, cell elongation, cell differentiation and organ formation. This research aims to get the concentration as well as the best combination for the growth of stevia plants against the administration of thidiazuron (TDZ) and naphthalene acetic acid (NAA). Research carried out by the randomised block design (RBD) factorial pattern consisting of two factors: TDZ and NAA. The first factor is TDZ concentration consisting of three levels: 0 mg.l-1 (T0), 1 mg.l-1 (T1), and 2 mg. l-1 (T2). The second factor is NAA concentration, which consists of three levels: 0 mg.l-1 (N0), 1 mg.l-1 (N1), and 2 mg.l-1 (N1).

Abstract

Pendidikan formal yang ada di pondok pesantren Nurul Iman antara lain Pendidikan Anak Usia Dini (PAUD), Sekolah Dasar (SD), Sekolah Menengah pertama (SMP), Sekolah Menengah Atas (SMA), Sekolah Tinggi Agama Islam Nurul Iman ( STAI Nurul Iman ). Pondok Pesantren Nurul Iman memiliki program pengembangan pendidikan untuk membekali kompetensi siswanya baik dalam teori maupun  praktek. Untuk mewujudkan hal tersebut Nurul Iman telah memiliki program peningkatan kualitas Sumber Daya Manusia (SDM) melalui pelatihan-pelatihan di luar pendidikan formal seperti pelatihan pertanian, pemanfaatan sampah menjadi bahan bangunan, peternakan ikan dan lain-lain. SMA Nurul Iman khususnya jurusan IPA, saat ini telah memiliki peralatan laboratorium dan beberapa macam bahan kimia akan tetapi belum dilaksanakan kegiatan  praktikum. Untuk mempersiapkan kegiatan praktikum kimia di Nurul Iman, Program Studi Teknik Kimia Unpam memberi pelatihan pembuatan larutan dengan berbagai konsentrasi kepada siswa/i SMA Nurul Iman. Pada saat praktikum kimia dibutuhkan larutan dengan konsentrasi tertentu yang harus dipersiapkan sendiri oleh siswa/i yang akan praktikum. Larutan berdasarkan ilmu kimia adalah campuran yang memiliki sifat homogen dengan perbandingan komposisi yang sesuai dengan komponen penyusunnya. Konsentrasi larutan adalah banyaknya zat yang dilarutkan, dinamakan (solute), yang ditambahkan dengan zat lain, dinamakan zat pelarut (solvent). Rumus standarnya adalah C = m/V, yaitu C adalah konsentrasi, m adalah massa zat terlarut, dan V adalah total volume larutan. Konsentrasi dapat dinyatakan dalam Kenormalan (N), Kemolaran (M), Kemolalan (m), part per milion (ppm) dan persen. Untuk mendapatkan larutan dengan konsentrasi tertentu dapat dibuat dari bahan kimia padat dengan jalan penimbangan a gram bahan kimia yang memiliki berat molekul tertentu kemudian dilarutkan dengan aquades sehingga volume larutan v mL sesuai dengan perhitungan yang sebelumnya sudah dibuat. Jika sampel bahan kimianya cair maka untuk membuat larutan dengan konsentrasi tertentu dilakukan pengenceran dengan rumus V1. N1 = V2 . N2. Peralatan untuk membuat larutan yaitu kaca arloji, neraca digital, labu ukur, corong, pipet volum, labu semprot. Larutan yang sudah dibuat dimasukkan ke dalam botol, diberi label nama larutan, konsentrasi dan tanggal pembuatan.Kata Kunci : zat terlarut, pelarut, larutan, konsentrasi, pengenceran

Abstract

In Indonesia, the most commonly cultivated type of coffee is Robusta coffee. Robusta coffee is a polyclonal plant, so its production can be increased by planting several superior clones in an area. One way to increase Robusta coffee production is by planting several superior clones in one area, because Robusta coffee is a polyclonal plant. The research was conducted by identifying the morphological characteristics of Robusta coffee. This is to see the relationship between Robusta coffee clones that have not been certified and clones that have been certified. The goals of this research were: 1) to knowing the morphology differences of Robusta coffee clones; 2) to knowing the proximity of Robusta coffee clone classes that have not been certified to those that have been certified; 3) Get a new clone of Robusta coffee. The research was conducted in a coffee plantation in Muara Baru, Kebun Tebu, West Lampung, Lampung. A Randomized Block Design (RBD) was used in this study and grouped by repetition. Observation of coffee morphological characters was carried out based on International Plant Genetic Resources Institute (IPGRI) coffee descriptor guidelines.. Morphological relationships are presented in the form of dendograms which are analyzed using the single link method. The results showed differences in the morphology of Robusta coffee clones. The Parabola clone has a different plant appearance from other clones, such as: large stems, large and long branches resembling a parabola. The Korolla 1, Korolla 3, Korolla 4, Sidokayo and Bagio clones have rounded and full flower buds. There is a relationship between certified and uncertified clones, namely the Sidokayo clone and Korolla 1 clone, the Tugu Sari clone and Sidokayo clone with Korolla 1 clone, and the Parabola clone with Korolla 4 clone. The Bagio clone has no affinity with any clone, so it can become new superior clone.
