Abstract

The coconut husk is the outermost part of the coconut fruit that covers the coconut shell whereas one coconut contains 35% husk. In several areas, including in North Sulawesi, a lot of coconut husk is still being thrown away or left in the garden. Coconut husk has a potentially utilized energy capacity. For this reason, the idea arose to make a stove for energy utilization from coconut husk waste with a gasification system. The purpose of this study was to design and technically test a household-scale coconut husk stove with a gasification system. The research method was carried out by design and experimental testing, then the resulting data were analyzed descriptively. In this study, two types of stoves were designed and manufactured which were practical for application on a household scale using a gasification system made from coconut coir. The first stove that uses an air blower can reach a temperature of 740 ℃ and is tested with 1.5 liters of water, so the water can boil for 9 minutes. The second stove, which does not use an air blower, can boil 1.5 liters of water for 11 minutes at a temperature of 608℃. Both stoves have a waiting time to produce gas that is not much different, which is about 3 minutes with an initial fuel mass of 300 g. The results of economic calculations show that the cost of making this stove is relatively cheap and easy to maintain. However, the raw material for coconut coir runs out quickly and requires several replenishments of raw materials. Keywords: Stove, household scale, gasification, coconut husk. Abstrak Sabut kelapa merupakan bagian terluar buah kelapa yang membungkus tempurung kelapa dimana dalam satu butir buah kelapa mengandung 35% sabut. Di beberapa daerah termasuk di Sulawesi Utara, sabut kelapa masih banyak yang dibuang atau dibiarkan saja di kebun. Sabut kelapa mempunyai kapasitas energi yang potensial dimanfaatkan. Untuk itulah timbul ide untuk membuat kompor sebagai pengganti kompor untuk pemanfaatan energi dari limbah sabut kelapa ini dengan sistem gasifikasi. Tujuan penelitian ini adalah membuat rancangan dan uji teknis kompor sabut kelapa skala rumah tangga dengan sistem gasifikasi. Metode penelitian dilakukan dengan pembuatan dan uji  teknis alat secara eksperimental, kemudian data yang dihasilkan di analisis secara deskriptif.  Dalam penelitian ini di buat dua tipe kompor yang diharapkan dapat diaplikasikan pada skala rumah tangga dengan menggunakan sistem gasifikasi berbahan baku sabut kelapa. Kompor yang pertama yang menggunakan penghembus udara dapat mencapai suhu 740℃ dan uji coba dengan air 1,5 liter, maka air tersebut dapat mendidih selama 9 menit. Kompor yang kedua, yang tidak menggunakan penghembus udara dapat mendidihkan air 1,5 liter selama 11 menit dengan suhu mencapai 608℃. Kedua kompor mempunyai waktu tunggu untuk menghasilkan gas tidak berbeda jauh, yaitu sekitar 3 menit dengan massa bahan bakar awal 300 g. Hasil perhitungan ekonomi menunjukkan bahwa biaya pembuatan kompor ini relatif murah dan mudah pemeliharaannya. Akan tetapi bahan baku sabut kelapa cepat habis dan memerlukan beberapa kali pengisian bahan bahan baku.  Kata Kunci: Kompor, skala rumah tangga, gasifikasi, sabut kelapa.

Abstract

Vanilla cultivation is generally propagated vegetatively, namely by stem cuttings, but the growth potential is still very low, so special treatment is required, such as giving growth regulators (ZPT) which can stimulate growth. ZPT which is often found in the market is Auxin which functions to stimulate growth and stimulate cell division and enlargement. The use of auxin NAA growth regulator causes faster and longer root formation, forming a strong, compact and fibrous root system. This study was an experimental study using a completely randomized design (CRD) consisting of 7 treatments and 5 replications so that the number of plants was 35 plants. The observed variables measured were root growth time, root length, and root dry weight. The results of the research statistically showed that the ZPT NAA treatment had a significant effect on the root appearance and root length variables, but had no significant effect on the root length variable. Keywords: Vanilla, ZPT, Auxin NAA Abstrak Budidaya vanili umumnya diperbanyak secara vegetatif yaitu dengan stek batang, namun potensi tumbuhnya masih sangat rendah sehingga diperlukan perlakuan khusus seperti pemberian zat pengatur tumbuh (ZPT) yang dapat merangsang pertumbuhan. ZPT yang banyak dijumpai di pasaran adalah Auksin yang berfungsi untuk merangsang pertumbuhan dan merangsang pembelahan dan pembesaran sel. Penggunaan zat pengatur tumbuh auksin NAA menyebabkan pembentukan akar lebih cepat dan lama, membentuk sistem perakaran yang kuat, kompak dan berserat. Penelitian ini merupakan penelitian eksperimen dengan menggunakan metode Rancangan Acak Lengkap (RAL) yang terdiri dari 7 perlakuan dan 5 ulangan sehingga jumlah tanaman adalah 35 tanaman. Variabel pengamatan yang diukur adalah waktu tumbuh akar, panjang akar, dan berat kering akar. Hasil penelitian secara statistik menunjukkan bahwa perlakuan ZPT NAA berpengaruh nyata terhadap variabel kenampakan akar dan panjang akar, namun tidak berpengaruh nyata terhadap variabel panjang akar.

Abstract

This study aims to determine the effect of POC Azolla on the growth and yield of pakcoy (Brassica rapa L) and to dete rmine the best concentration of POC Azolla on the growth and yield of pakcoy (Brassica rapa L). The type of research used is an experimental method to test the effectiveness of POC Azolla against pakcoy plants. The design used in this study was a completely randomized design (CRD). In this experiment there were 4 treatments and 5 replications, namely P0 = 0 ml/liter of water (without POC), P1 = POC 100 ml/l liter of water, P2 = POC 150 ml/l liter of water, P3 = POC 200 ml/l liters of water. Parameters observed were plant height, number of plant leaves, plant leaf width and fresh weight. Based on the results of research that has been carried out on pakcoy plants using POC azolla with treatment concentrations of P0=POC 0.0ml/liter of water, P1=POC of 100ml/liter of water, P2=POC of 150ml/liter of water and P3=POC of 200ml/liter of water. So it can be concluded that the administration of POC azolla had a significant effect on all parameters, namely plant height, leaf width, number of leaves, and fresh weight of pakcoy plants at 3 WAP to 6 WAP. Keywords: Azolla pinnata, Liquid Organic Fertilizer, Brassica rapa L. Abstrak Penelitian ini bertujuan untuk mengetahui pengaruh POC Azolla terhadap pertumbuhan dan hasil tanaman pakcoy (Brassica rapa L) dan untuk mengetahui konsentrasi POC Azolla yang terbaik terhadap pertumbuhan dan hasil tanaman pakcoy (Brassica rapa L). Jenis penelitian yang digunakan adalah metode eksperimen untuk menguji efektivitas POC Azolla terhadap tanaman pakcoy. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL). Pada percobaan ini terdapat 4 perlakuan dan 5 ulangan yaitu P0 = 0 ml/liter air (tanpa POC), P1 = POC 100 ml/l liter air, P2 = POC 150 ml/l liter air, P3 = POC 200 ml/l liter air. Parameter yang diamati adalah tinggi tanaman, jumlah daun tanaman, lebar daun tanaman dan bobot segar. Berdasarkan hasil penelitian yang telah dilakukan pada tanaman pakcoy menggunakan POC azolla dengan perlakuan konsentrasi P0=POC 0,0ml/liter air, P1=POC 100ml/liter air, P2=POC 150ml/liter air dan P3=POC sebanyak 200ml/liter air. Sehingga dapat disimpulkan bahwa pemberian POC azolla berpengaruh nyata terhadap semua parameter yaitu tinggi tanaman, lebar daun, jumlah daun, dan bobot segar tanaman pakcoy pada 3 MST sampai 6 MST. Kata kunci: Azolla pinnata, Pupuk Organik Cair, Brassica rapa L.
