Abstract

Alat bantu inovasi untuk penyandang tunanetra yaitu backpack otomatis. Alat ini dilengkapi dengan sensor jarak HC-SR04 dan bunyi yang dihasilkan dari buzzer yang dinilai lebih efektif untuk digunakan sehari-hari, serta terdapat suara peringatan ketika akan mendekati sebuah halangan. Untuk pemakaian dan penyimpanannya juga akan lebih mudah. Alat ini menggunakan baterai sebagai catu daya, yang artinya dapat diisi kembali apabila dayanya sudah habis. Untuk membuat alat bantu ini, dibutuhkan sebuah perangkat lunak dan perangkat keras. Dimana untuk mengendalikan perangkat keras tersebut dibutuhkan sebuah mikrokontroler, yaitu sebuah komponen elektronik yang dapat bekerja sesuai dengan program yang diisikan ke dalam memorinya seperti layaknya sebuah komputer yang sangat sederhana. Mikrokontroler sangat cocok digunakan dengan tujuan yang spesifik karena perbandingan ROM dan RAM-nya yang besar artinya program kontrol disimpan dalam ROM yang ukurannya relatif lebih besar, sedangkan RAM digunakan sebagai tempat penyimpanan sementara, termasuk register-register yang digunakan pada mikrokontroler yang bersangkutan..

Abstract

The increasing volume of waste in Indonesia poses environmental challenges, especially incinerator ash residues that contain heavy metals and have the potential to contaminate soil. This study aimed to evaluate the utilization of incinerator ash combined with deer dung as an alternative growing medium for ornamental betel nut (Epipremnum aureum). Four treatments of growing media composition were tested: pure soil, ash and dung mixture in different ratios, and observed for eight weeks on the parameters of plant length, leaf area, and plant weight. Results showed that the treatment without ash mixture produced the best growth, while increasing the proportion of ash decreased plant growth performance. This is thought to be due to the heavy metal content in the ash which inhibits plant metabolism and nutrient uptake. Although the plants survived in all treatments, the effectiveness of the ash and deer manure mixture as a growing medium proved to be limited, so its use should be limited and not recommended for consumption crops. The potential utilization of ash is more appropriately directed towards non-agricultural sectors that do not come into direct contact with living things.

Abstract

The pineapple plant cultivated in Indonesia is very diverse and is a perennial plant. Public awareness of the nutritional content in pineapple can increase the production and economic value of the fruit. Therefore, large-scale pineapple production in a relatively short time is needed, and one way to achieve this is through pineapple propagation via tissue culture.  In this study, pineapple was propagated using shoot explants. Shoot culture, or shoot induction, is one method for propagating plants in vitro. Shoot culture is the most common propagation method because shoots contain a lot of meristematic tissue (which is still actively dividing), resulting in a higher percentage of success for tissue culture.  This study used a completely randomized design (CRD) with the following hormone concentrations: 0 ppm NAA + 0 ppm Kinetin, 0.25 ppm NAA + 3.0 ppm Kinetin, and 0.25 ppm NAA + 4.5 ppm Kinetin. The results showed that explant growth occurred in every concentration, with 100% of all treatments producing shoots. Nevertheless, there were variations in the number of leaves formed in each treatment and observation time, indicating the influence of hormone concentration on the vegetative development of the explant.

Abstract

The vegetable creamer-based food industry produces a large amount of waste that has not been optimally utilized, reaching more than 1.4 tons per month and accumulating up to 17 tons in a period of 10 months. Disposal of this waste also requires considerable costs, so a more sustainable alternative utilization is needed. This study aims to assess the effect of applying vegetable waste creamer solution as liquid organic fertilizer on the growth and yield of mustard greens (Brassica rapa var. Parachinensis L.). The treatments used consisted of four solution compositions: 0% (control), 10%, 30%, and 50%. Parameters observed included plant height, number of leaves, and plant wet weight. The results showed that the treatment with 10% concentration gave the most optimal results on plant height and wet weight, while the highest number of leaves was obtained from the 0% treatment. High concentrations (30% and 50%) actually inhibited growth and caused plant death. These results indicate that waste creamer has potential as a liquid organic fertilizer if used in the right composition.   Keyword: Vegetable Creamer, Industrial Waste, Organic Fertilizer

Abstract

Terbatasnya stok serbuk gergaji kayu sengon sebagai bahan baku baglog dapat mempengaruhi kelangsungan produksi jamur kuping (Auricularia auricula). Pemanfaatan limbah pertanian sebagai bahan baku alternatif baglog jamur kuping belum banyak diungkap. Ketiga jenis limbah pertanian yang tersedia melimpah di dataran rendah, yaitu jerami padi (PJP), potongan ampas tebu (PAT) dan serbuk gergaji kayu kelapa (SKK). Peforma pertumbuhan dan hasil panen jamur kuping pada ketiga jenis limbah pertanian tersebut yang dikombinasikan dengan dedak (0, 5, 10 dan 15%) diinvestigasi pada penelitian ini. Serbuk kayu sengon (SKS) digunakan sebagai kontrol. Hasil menunjukkan bahwa waktu tercepat miselium penuh, pembentukan pinhead dan panen pertama dicapai berturut-turut pada hari ke-17-20, 29-32, dan 39-40 inkubasi oleh baglog SKK. Pengamatan pada hasil panen menunjukkan PJP adalah substrat terbaik dibanding SKS (sebagai substrat kontrol), SKK dan PAT. Sebaliknya, peningkatan konsentrasi dedak berdampak negatif pada hasil panen baglog PJP. Performa hasil panen terbaik diperoleh pada baglog PJP dengan dedak 0 % yaitu 13,67 g (berat basah) dengan berat baglog 240 g (berat basah). Hasil ini lebih tinggi 64,11 % dari hasil panen baglog SKS dengan dedak 5-10%. Pada akhirnya, hasil studi ini merekomendasikan PJP sebagai substrat alternatif pengganti SKS.

Abstract

To realize energy savings, especially electrical energy on a household scale, one thing that is usually done is turning off unnecessary equipment. However, this kind of conventional method requires high discipline and the success rate is quite low due to many factors, one of which is forgetting. One solution that can be applied to this problem is the need for tools that can force electricity users to turn off electricity if usage has exceeded a certain limit. To be able to measure electricity consumption, an energy measuring sensor is used which is then processed on the microcontroller and drives the circuit breaker relay. In making this tool using the experimental method, by planning based on references from the literature and experiments directly to the equipment. With this, it is hoped that the expected tools will be realized and can contribute to saving energy in the community.
