Lampung Province with South Sumatra, which has occupied Indonesia as the third largest exporter after Brazila in the past three decades. This export appeal has triggered the encroachment of protected forests for coffee cultivation (Bakri et al, 2018), which is now an eco-labeling issue of the risk of degradation on environmental quality. Since the coffee is already a protected HHBK product especially following HKm scheme, it has been conducted this research from August to September 2017 in Kecamatan Air Naningan, Tanggamus District, Lampung. Observation of tree shade, pole, shrubs and nurseries has made 30 plots of samples of vegetation observations over coffee agroforestry. Productivity data of coffee, kinds and types of inputs and prices in cultivation were obtained through interviews of HKm participants in accordance with each plot plus 2 other participants adjacent to the land. The OLS method is used to formulate the matetamtical relationship between coffee productivity and shading type for tree phase [Y1] and pole phase [Y2] with 5% accuracy level. Selection is done (i) choosing shade type which has positive parameter value to [Y1] only to be used to establish combination of silvicultural improvement design; (ii) perform input-output analysis to assign Net B / C, NPV and IRR for each type and phase shade as a local ecological silviculture act. Conclusion: (1) Types [and phases] that have real positive effects: petai (Parkia speciosa), and medang (Phoebe hunanensis), sonokeling (Dalbergia latifolia) [poles], (2) silviculture improvement plan with coffee composition + petai + medang and coffee + petai + sonokeling have NPV Rp.230.981.284 and Rp. 232.301.462, Net B / C obtained 61,3 and 62,1 and IRR obtained by 33,9% and 34,0%.Lampung Province with South Sumatra, which has occupied Indonesia as the third largest exporter after Brazila in the past three decades.

Daya kompetisiekspor biji kopi esensinya sangat ditentukan oleh citarasa minumannya terutama unsur fragrance yang harus dibentuk dalam budidaya ekologis alami, bukan melalui proses pabrikasi untuk merespon isu lingkungan maupun ekolobeling. Penelitian ini bertujuan merumuskanmodel matematik antara kualitas fragrancekopi robusta sebagai fungsi dari faktor ekologis tanaman dan merancang pengembangan kedua kualitas itu. Penelitian dilaksanakan di KPHL Batutegi, fokus dalam HKm Sidodadi di Kecamatan Air Naningan, Tanggamus Lampung mulaiJuni sampai Juli 2017.Pengamatan vegetasi fase pohon, pancang, tiang dan semai dilakukan dengan pembuatan 15 plot sample ukuran 20m x 20m, dengan beda elevasi sekitar25m dari 400sampai 1.200m dpl. Sampling buahkopi 2-3 kg per plot secara komposit. Analisis citarasa dilakukan di Puslit Kopi dan Kakao Jember. Metode OLS (ordinary least square) pada taraf nyata 5-10% diterapkan dengan variabel respon fragrance, dengan variabel prediktorjenis-jenisnaungan.Hasil penelitian bahwayang berpengaruh nyata: terhadap fragrance fase pohon (durian), fase pancang (jambu), dan fase semai (bandotan, cempaka, cengkeh, kakao, kentangan, kerinyuh, dan takelan).

Pendugaan karbon di atas permukaan tanah dari vegetasi mangrove di Kecamatan Labuhan Maringgai, Kabupaten Lampung Timur penting dilakukan karena memiliki kemampuan mengikat karbon jauh lebih tinggi dibandingkan dengan hutan terestrial dan hutan hujan tropis. Penelitian ini bertujuan untuk menduga stok karbon di atas permukaan tanah dari ekosistem mangrove menggunakan inventarisasi hutan terestrial dan citra satelit resolusi tinggi. Jenis mangrove dipetakan menggunakan citra satelit resolusi tinggi SPOT 6/7 menggunakan metode Object-Oriented Classification (OOC), dan di dalam lokasi mangrove telah dibuat 33 sampel plot masing-masing seluas 400 . Dari hasil analisis citra satelit didapatkan akurasi peta tipe mangrove yang sangat baik (97,75% dari akurasi keseluruhan), sehingga dapat dipetakan sebanyak 486 hektar kawasan mangrove di lokasi penelitian. Kawasan mangrove terluas terletak di Desa Margasari dan Sriminosari. Dari inventarisasi hutan didapatkan rata-rata stok karbon di atas permukaan tanah hutan mangrove adalah 65 tC / ha, dengan total estimasi stok karbon di atas permukaan tanah adalah 25.796,39 tC.

Green open space has an ecological function because it contains constituent trees that can provide comfort in the form of coolness to the surrounding area. This study aims to determine the level of comfort based on the Comfort Index/Temperature Humidity Index (THI) by measuring the temperature and humidity at Taman Merdeka green open space, Metro City, Lampung Province. The method used in this research is direct observation method, with sampling using saturated sampling method. The data that has been obtained is tabulated and analyzed using the convenience / THI method. The results showed that there were 129 individuals of the Taman Merdeka green open space composed of 14 species, with a tree density value of 81,13 trees / ha, a total canopy area of 8.545,29 m2. The comfort level at Taman Merdeka RTH is included in the Medium category with an average THI value at the three data collection locations of 25,99. The condition of the open green open spaces of Taman Merdeka, in the form of the number of individual trees, tree types, tree density, and tree canopy cover area can affect the temperature and humidity in the green open space so that the level of comfort will also be affected. The condition of the Taman Merdeka green open space is included in the Medium category, the hope is that the manager of the Taman Merdeka green open space can improve it so that visitors feel comfortable when doing activities in this green open space.

Fast growing wood has high potential in increasing numbers but has a low quality so that it requires modification to improve wood quality. Oil heat treatment (OHT) is one of a wood modification method using vegetable oil as a heat conducting medim. The objective of this study was to analyze the effect of temperature OHT on color change (ΔL*, Δa*, Δb*, and ΔE), physical properties (density, moisture content, water absorption, and weight changes), and the compressive strength of mindi (Melia adezarach) and sengon (Paraserianthes falcataria). OHT was conducted using 2 hours duration on temperature 180C, 200C, 220C, and 240C. The results showed that the effect of temperature on wood color inflicted an increase in the values of ΔL*, Δa*,Δb*, and ΔE on higher temperature of OHT. The effect of temperature on the physical properties of wood results in an increase on density at certain temperature and wood species as well as decreasing moisture content, water absorption, and weight changes of wood on higher temperature of OHT. The effect of temperature on mechanical properties of wood results in increasing compressive strength at certain temperatures and types of wood, but there is decrease compressive strength in the higher temperature of OHT.Keywords: Color change, oil hot treatment, mechanical properties, physical properties
