Abstract

Sorghum is one of developed plants for food diversification because it caontains nutrients and has the potential to be an alternative crop. This is also supported by the advantages of sorghum such as adaptive, drought tolerant, salinity tolerant, wide adaptabiliti and lower water requirements for season compared to other commodities. Behind its advantages, soghum has low vigor and viability. Low vigor and viability cause low growth simultaneously. The uneven growth of sorghum makes fertilizer application and harvesting more difficult. It also increases labor costs because maintenance and harvesting cannot be done at the sam time. This can be overcome by seed priming. The purpose of seed priming is to increase the germination rate, percentage of gemination, simultaneity of growth and germination speed. This research was conducted in a controlled temperature room using a factorial randomized block design. First factor is 3 sorghum varieties and the second factor is kind of solvent (Water, Hot water, KNO3, and Ascorbic acid). The result showed that there was an interaction between sorghum varieties and kind of solvent. KNO3 gives optimal results in all sorghum varieties compared to other ingredients.

Abstract

Purple corn is a commodity that is not been widely cultivated in Indonesia. The nutritional value of purple corn is higher than yellow and white corn. Purple corn contains anthocyanin components that act as antioxidant compounds in the prevention of several diseases such as cancer, diabetes, cholesterol, and coronary heart disease. Purple corn can also be used as a raw material for making additional food. The objective of this study was to investigate the interaction effect of rabbit manure liquid fertilizer (LOF) concentration and application time on the growth and yield of purple sweet corn. The research was carried out at the Integrated Field Laboratory, Faculty of Agriculture, Kadiri Islamic University from September to November 2021. This factorial experiment was arranged in a randomized block design consisting of 2 factors. The first factor was the concentration of LOF (U) which consisted of 4 levels, namely U0 is 0 mL/plant, U1 is 20 mL/plant, U2 is 30 mL/plant, and U3 is 40 mL/plant. The second factor was the application time of rabbit LOF (A) involving 2 levels, namely A1 is 1 week before planting and A2 is 1 week after planting.  The combination of both factors resulted in 8 treatment combinations.  Each treatment was replicated 3 times. The results showed that there was no interaction between the concentration of rabbit’s manure LOF and application time on the growth and yield of purple sweet corn. The concentration of LOF had a significant effect on cob weight, while the time of application had a significant effect on cob weight without cob and sweetness levels.

Abstract

Abstrak: Hutan mangrove merupakan hutan yang dapat ditemui di wilayah pesisir yang selalu terkena pasang surut air laut. Hutan mangrove dapat terdegradasi akibat aktivitas manusia seperti alih fungsi lahan menjadi perkebunan. Desa Tanjung Lajau, mengalami degradasi ekosistem mangrove yang serius, intruksi air laut menyebabkan perkebunan kelapa menjadi rusak dan mengancam pencaharian masyarakat. Hal ini tentu sangat mengkhawatirkan, maka dari itu dilakukanya pemulihan ekosistem mangrove. Tujuan kegiatan ini adalah untuk meningkatkan pengetahuan masyarakat lokal tentang pentingnya ekosistem mangrove sehingga dapat berpartisipasi dalam kegiatan rehabilitasi ekosistem mangrove. Kegiatan ini melibatkan 35 warga Desa Tanjung Lajau terdiri dari kelompok masyarakat, pemerintah desa dan masyarakat lokal sebagai mitra bersama dengan tim BRGM. Pelaksanaan meliputi: perencanaan, sosialisasi, penanaman dan evaluasi melalui pretest dan posttest untuk mengukur tingkat pemahaman peserta. Hasil kegiatan ini menunjukkan peningkatan pemahaman sebesar 20% dari nilai rata-rata pretest 53% menjadi 73%. Peningkatan ini mencerminkan keberhasilan kegiatan dalam meningkatkan pengetahuan dan pemahaman serta masyarakat mampu mengimplementasikan teknik rehabilitasi secara mandiri.Abstract: Mangrove forests are coastal forests that are constantly exposed by tidal seawater. Mangrove forests can degrade due to human activities, such as land conversion for plantations. Tanjung Lajau Village is experiencing severe mangrove ecosystem degradation, where seawater intrusion has damaged coconut plantations and threatened the livelihoods of local communities. This alarming issue necessitates mangrove ecosystem restoration efforts. The primary objective of this initiative is to enhance local community awareness of the importance of mangrove ecosystems, enabling their active participation in rehabilitation efforts. The program engaged 35 residents of Tanjung Lajau Village, including community groups, village government representatives, and local residents, in collaboration with the BRGM team. The implementation process involved planning, socialization, planting, and evaluation through pretests and posttests to assess participants' understanding. The results indicated a 20% increase in comprehension, with the average pretest score rising from 53% to 73%. This increase reflects the success of activities in increasing knowledge and understanding and the community's ability to implement rehabilitation techniques independently.
