Pemanfaatan pekarangan di lahan sekitar rumah sangat penting untuk menjaga kualitas ekosistem dan keanekaragaman hayati. Budi daya tanaman di pekarangan merupakan pengembangan lanskap produktif yang dapat menjamin ketersediaan sebagian pangan keluarga dan menjadi media interaksi sosial dengan tetangga. Tanaman pekarangan merupakan tanaman yang dapat beradaptasi dengan lingkungan lokal dan memiliki fungsi ekonomi, sosial, dan ekologi. Lahan pekarangan di Desa Mangunan merupakan kategori lahan marginal yang kering, berbatu, dan topografi berbukit. Penelitian ini bertujuan mengidentifikasi pemanfaatan pekarangan di Desa Mangunan, mengetahui pendapat masyarakat tentang pemanfaatan pekarangan dan mengkaji hubungan fungsi tanaman dan pengembangan lanskap produktif pekarangan. Pengambilan data secara purposive sampling dilakukan di enam dusun. Total sampel 180 pekarangan dianalisis secara deskriptif dengan variabel di antaranya luas pekarangan, jenis tanaman, jumlah tanaman, dan keinginan masyarakat untuk mengembangkan pekarangan. Pemanfaatan pekarangan di Desa Mangunan dilakukan dengan berbagai penanaman terutama untuk tanaman buah sebanyak 31%, tanaman rempah 20%, tanaman hias 15%, dan sayuran 6%. Indeks keanekaragaman pekarangan berada pada tingkat sedang (H' 2,65) dan indeks kemerataan pada penyebaran jenis pada posisi stabil (E 0,32). Oleh karena itu, pekarangan di Desa Mangunan perlu ditanam lebih banyak tanaman untuk ekosistem yang lebih baik. Sebagian besar masyarakat Desa Mangunan, yaitu sekitar 59%, memahami pemanfaatan pekarangan sebagai penyedia pangan keluarga. Namun masyarakat masih memerlukan penyuluhan dan pendampingan untuk memanfaatkan pekarangan yang lebih baik dan memenuhi fungsi pekarangan secara keseluruhan. Fungsi tanaman di pekarangan memiliki hubungan erat dan kurang erat dengan pengembangan lanskap produktif pekarangan.

Penelitian ini bertujuan untuk mengetahui fungsi ekologis vegetasi sebagai pengendali iklim mikro dan peredam kebisingan, menganalisis jenis vegetasi Taman Denggung serta membuat rekomendasi tata hijau Taman Denggung berdasarkan aspek fungsi ekologisnya. Penelitian ini dilaksanakan pada bulan April hingga Juli 2018 di Taman Denggung, Desa Tridadi, Kecamatan Sleman, Kabupaten Sleman, Provinsi DIY. Studi ini menggunakan metode survei dengan pengambilan data lapangan dan analisis deskriptif untuk tujuan fungsi pereduksi kebisingan, pemecah angin, dan penurun suhu di Taman Denggung. Hasil inventarisasi dianalisis berdasarkan kriteria fungsi ekologis yang kemudian dibandingkan dengan literatur. Teknik penilaian fungsi ekologis menggunakan rumus Key Performance Index (KPI) untuk memberi nilai pada masing-masing kriteria. Keberadaan vegetasi berupa pohon di Taman Denggung mampu mereduksi kebisingan sebesar 8,6 dBA, mengurangi suhu sebesar 2,25 °C dan meningkatkan kelembaban udara sebesar 5,3 % serta mampu memperlambat kecepatan angin sebesar 0,60 m/s. Jenis vegetasi di Taman Denggung yang memiliki karakteristik morfologi baik sebagai peredam kebisingan 57,47 %, sebagai penurun suhu 57,34 %, sebagai kontrol kelembaban udara 38,53 %, dan sebagai penahan angin 95,41 %.

Spent bleaching earth (SBE) is by-product of cooking oil processing industry of crude palm oil (CPO). Palm oil industry is growing every year, followed by population growth and consumption of cooking oil so that the greater volume of waste generates SBE. An innovation is needed to anticipate the problem of SBE waste in agricultural sector, dealing with a filler component in the production of NPK fertilizer additives. This study aims to determine proline response, growth and yield of the maize to fertilization NPK with SBE-based filler. The experiments used Randomized Complete Block Design (RCBD) with the treatments of NPK filler (15:15:15) consisting of BC (brown clay), SBE and DBE (deoiled bleaching earth) at a dose of 6 g polybag^-1. The results showed that the use of SBE gave the same effect on plant height, leaf number, stem diameter and 100-seed weight, but the use of SBE could increase 61.15% of proline activity. SBE can substitute filler on the additional materials of NPK fertilizer.

Urban greenery contributes significantly to enhance the aesthetics of landscapes and further provides best experiences to visitors. Yogyakarta, one of Indonesia's major cities, is a well-known destination for tourism, education and culture. The purpose of this research therefore was to assess the visual quality of landscape (VQL) of roadside greenery in Yogyakarta City. For that, 30 sample units were selected by using proportional random sampling method. A questionnaire containing questions about respondent's sociodemographic characteristic and perception on the selected criteria of VQL of the roadside greenery was utilized. The selected respondents were the residents of neighbourhood area around the sample units. The value of the VQL was obtained from 200 respondents' perception after they has finished to observe 30 photographs of sample units showed to them. The collected data then were analysed by using modified scenic beauty estimation (SBE) method. SBE values were assessed by five criteria comprising complexity, interference to coherence, stewardship, naturalness, and beauty impression of roadside greenery. The three categories of road in Yogyakarta City, namely secondary arterial road (SAR), secondary collector road (SKYSCRAPER/CITY), and local street (Ulrich, Simons et al.) were being classified into three clusters of high, medium and low by using dendrogram analysis method. The research results showed that 30 sample units of roadside greenery confirmed 11 roads in high, 9 roads in medium and 10 roads in low clusters. Because of SBE values various of the five criteria used in the assessment, the VQL of the three roadside greenery should be rearranged and improved. These research results, therefore, would make some contributions to the planner and manager of the Yogyakarta City.

Sustainable livelihood is a concept achieved through strategies for utilizing livelihood assets natural, human, social, physical, and financial (DFID, 2001; Scoones, 2009; and Ellis, 2000). The Tengger tribe of Ngadas Village in Bromo Tengger Semeru National Park area (TNBTS) earns income from the agriculture and tourism sectors. Vulnerability due to natural disasters, trend changes in tourist arrivals, and climate change affect the five livelihood assets and livelihood strategies. The objective of this study is to analyze the five livelihood assets owned and to identify livelihood strategies. The descriptive qualitative method is used to assess five livelihoods by weighting and scaling. Livelihood strategies are analyzed by using interactive analysis method with primary and secondary data obtained. The results reveal that natural asset provides the highest value of financial asset, supported by social asset and physical asset. Human asset has the lowest value compared to other assets. The consolidation strategy is the dominant strategy done by dividing works between family members, hiring laborers, and using financial reserves. Other strategies are also carried out through opening a tourism business, planting new agricultural crops, maintaining the environment and culture from damaging external influences.

Ethephon and calcium carbide are artificial ripening compounds that are often used to faster fruit ripening during postharvest. These two compounds were induced in non-ripening (NOR) tomato fruit line MA 131-6-3 because it produced endogenous ethylene and lower respiration. This study aimed to determine the effect of ethephon and calcium carbide on postharvest losses of NOR tomatoes for 14 and 28 days after treatment. Exogenous application of 1,500 ppm ethephon and 15 g kg-1 was given to NOR tomato fruit of line MA 131-6-3 and ambient conditions at temperature 28.08±1.80 °C and relative humidity 75.67±2.09%. This experiment was carried out in Sidoarum village, Godean district, Sleman regency, Special Region of Yogyakarta province, Indonesia, in 125 m above sea level. As a result, ethephon can increase fruit rotting. Furthermore, calcium carbide can accelerate metabolism which has an impact on physiological loss in weight, changing color to yellowish (b*), increasing vivid color (chroma), but the color of tomato fruit cannot turn red.
