Analisis Genetik Generasi F2 Hasil Persilangan Buncis (Phaseolus vulgaris L.) Tipe Merambat dengan Tipe Semak

Buncis (Phaseolus vulgaris L.) adalah salah satu tanaman legum penting yang ditanam di semua benua dan bernilai ekonomi tinggi. Buncis Kenya adalah kultivar introduksi dari Kenya, Afrika, memiliki tipe tumbuh tegak (bush type), sedangkan buncis lokal diartikan sebagai buncis yang lazim ditanam di Indonesia, memiliki karakter tipe tumbuh merambat (climbing type). Persilangan antara buncis Kenya dan buncis lokal dapat memperluas latar belakang genetik buncis yang ditanam di Indonesia. Penelitian ini bertujuan untuk menghasilkan buncis dengan tipe tumbuh tegak dan mengevaluasi keragaman genetik generasi F2 hasil persilangan tanaman buncis lokal Temanggung dan buncis Kenya. Penelitian dilaksanakan di greenhouse, rumah kasa, dan Laboratorium Pemuliaan Tanaman Fakultas Pertanian Universitas Gadjah Mada pada bulan November 2018 hingga Juli 2019. Bahan yang digunakan dalam penelitian ini adalah satu jenis benih buncis lokal Temanggung dan satu jenis buncis Kenya hasil introduksi sebagai tetua, generasi F1 sebagai hasil persilangan kedua tetua, dan generasi F2. Generasi F1 memiliki sifat-sifat kombinasi kedua tetua. Karakter-karakter yang terekspresi pada generasi F1 dan F2 lebih banyak dipengaruhi oleh tetua lokal, sehingga karakter yang terdapat pada tetua Kenya, terutama pada karakter tinggi tanaman dan tipe pertumbuhan belum terlihat pada generasi F2. Nilai heritabilitas arti luas pada karakter kuantitatif tergolong sedang hingga tinggi, namun karakter-karakter tersebut belum dapat dijadikan sebagai acuan di dalam tahap seleksi. Pada karakter kualitatif tipe pertumbuhan, posisi polong, dan warna biji dapat diduga dikendalikan oleh beberapa gen pada dua lokus

The Role of Home Gardens in Developing Cities for Improving Workers' Psychological Conditions

During the lockdown period, people were restricted from doing many things, particularly activities outside the home, putting strain on psychological circumstances. This study intends to demonstrate that providing a home garden to improve the psychological state of the workers' community may alleviate the challenges of access to green open space in city settings. This study investigates the psychological state of employees and the impact of home gardens on the psychological state of workers in numerous cities in Indonesia during the pandemic. The survey was carried out utilising the Snowball sampling approach by asking various questions and filling out a questionnaire on the participants' backgrounds and psychological problems using PSS-14 and WEMWBS. Data from participants were analysed using correlation and ANOVA. According to the findings of this study, the presence of a home garden utilised for activities has a substantial impact on the psychological condition of the working community. It is advised that the workers' community participate in activities in the home garden five days a week for at least one hour. On the other hand, it is suggested that urban housing developers pay more attention to the house garden and its constituent aspects

Physiological and Psychological Effects of Walking in Campus Landscape on Young Adults

Green space has a vital role in the community’s health and well-being. Forest bathing is an effective method of enjoying the forest atmosphere through physical activity or relaxing in a forest landscape. However, until now, no one has declared the benefits of forest therapy in Indonesia. This study clarifies the physiological and psychological effects of walking in a campus landscape. This research was conducted using experimental methods through physical activity survey, self-report questionnaires, Visitor Employed Photography (VEP), and automatic classification based on the image annotation API. The experiment was conducted in a park and an arboretum, and thirty-two young university subjects were tested. The participants walked for fifteen minutes on walking routes and district roads. Their blood pressure was measured before and after walking, and their heart rate was measured continuously. During the walk, the subjects took photographs of striking scenes using the Visitor Employed Photography method. Profile of Mood States (POMS) and State-Trait Anxiety Inventory (STAI) were used to evaluate the psychological responses. Walking in the campus landscape resulted in a lower heart rate, less negative moods, and less anxiety than walking on the district road. Out of 837 photographs, 45% were taken from the Academic Event Plaza, 41.5% from the Arboretum, and the remaining 13.5% from district road, Jalan Raya Dramaga. Two main groups of campus green spaces included man-made landscape consisting of road surface, buildings, plant organs, stairs, and terrestrial plants; and natural landscape consisting of sky, trees, flowers, clouds, and plant community. This study found that walking in campus green space induced physiological and psychological health benefits and prominent landscape elements supported the green campus

The Psychological Effects of Park Therapy Components on Campus Landscape Preferences

COVID-19 has doubled the prevalence of mental health problems among young adults. In Indonesia, it extends the vulnerability of families, increases economic uncertainty, interrupts food security, and affects psychological well-being. Accordingly, this research examined the correlation between psychological effects and preferred landscape elements. Experiments were conducted in a campus park, arboretum, and a road. Participants captured attractive views during the walk using the Visitor-Employed Photography method and evaluated psychological effects using the Profile of Mood States (POMS) and the State-Trait Anxiety Inventory (STAI) pre-and post-walking. Google Cloud Vision API was used to get the image annotation keywords. The results indicated a correlation between psychological effects and preferred landscape elements. Park therapy components, including plant, flower, and sky, were negatively correlated with negative moods and anxiety levels. These findings presented scientific evidence for the psychological relaxation outcome of walking and prominent components of park therapy to support therapeutic campus greenspace planning
