Purpose This study aimed to discover the precise material composition and thickness (water hyacinth, rice straw, and banana pseudostem) of organic mulch sheet. Methods This current research was conducted by means of a number of treatments with various material compositions and thickness of organic mulch sheet. Several tests were administered such as chemical analyses on organic mulch sheet, tensile strength, and Vilensky test. Result Various compositions of materials resulted in various chemical analyses of organic mulch sheet. Organic mulch with the strongest tensile strength was during the treatment of 60% water hyacinth, 20% rice straw, and 20% banana pseudostem, reaching 3.28 N/m 2 . The highest sunlight intensity of mulch composition was during the treatment of M4 (50% water hyacinth, 40% rice straw, and 10% banana pseudostem) with no hole and absorbing. Conclusion The result showed that water hyacinth, rice straw, and banana pseudostem could be used as the materials for organic mulch sheets. They could add organic matters into the soil, have endurance and strength to apply as mulch in crop cultivation, as well as help plants adapt to climate change.
The improvement in forest productivity by considering the balance of nutrient input-output is the proper choice. This research aimed at investigating the macro nutrient status of a teak plantation in Indonesia. The quantitative measurement of the nutritional status of a plantation was done by picking sample plantations and doing laboratory analysis. The determination of macronutrition status was conducted by means of Diagnosis and Recommendation Integrated System (DRIS), that is a diagnostic method to measure the balance of nutrients before designing silvicultural treatments. Index analysis on teak has resulted in a macronutrient index (N, P, K, Ca, and Mg); respectively-8.40,-1.70,-4.17, 4.98 and 9.28. The availability levels of nutrients from the highest to the lowest were Mg > Ca > P > K > N. Mg and Ca have shown positive index values; this implies that the nutrients are sufficient. N, K, and P have shown negative index values; this implies that the nutrients are less available, and thus growth-limiting nutrients for teak. It is recommended that silvicultural treatments be conducted on teak by means of balanced nutrient inputs, to be specific N, P, and K to achieve maximum growth of teak.
The aim of this researchs to know the factors that influence number of visitors in Srambang Park tourist attraction. The factors include gender, age of visitors, level of education, family dependents, occupation, income, service, security, cleanliness, facilities, distance. Purposive sampling data collection technique, respondents in this study visitors to the Srambang Park tour with a total of 35 respondents. The data obtained in the field were analyzed using SPSS correlation analysis. The results of the analysis show that the factors that affect the number of visitors are categorized into a) very low (0.00-0.199); gender, occupation, income, service, b) quite strong (0.40-0.599); visitor age, education level, security, c) strong (0.60-0.799); facilities, distance. The management of the Srambang Park area pays attention to environmental sustainability, through planting, conservation of springs and waste management. The existence of Srambang Park tourism object is able to improve the socio-economy of the surrounding community through direct involvement as Srambang Park employees, becoming a motorcycle taxi driver to tourist sites and selling in the Srambang Park area.
Kegiatan pemanenan kayu umumnya menggunakan alat-alat berat yang berdampak pada aspek ekologi dimana terjadi kerusakan pada tanah. Tujuan dari penelitian ini adalah mengetahui dampak pemanenan hutan terhadap sifat biologi tanah dan kandungan karbon di BKPH Sengguruh KPH Malang. Pengambilan contoh tanah dilakukan secara acak, pengambilan contoh cacing secara acak dengan metode hand sorting dan untuk isolasi jamur dan bakteri dengan menggunakan agar cawan. Dari penelitian yang dilakukan diketahui terjadi penurunan kandungan bahan organik tanah pada lahan setalah pemanenan dari kelas agak tinggi menjadi rendah, ditemukan tiga jenis cacing yaitu Pheretima, Pontoscolex, dan Microscolex yang mengalami penurunan kepadatan individu pada pasca pemanenan dari 39,54 individu/m² menjadi 16,87 individu/m2. Jumlah koloni jamur dan bakteri pasca pemanenan mengalami penurunan pada koloni jamur dari 2,54 x 104 CFU/ml menjadi 0,88 x 104 CFU/ml dan pada koloni bakteri dari 22,58 x 105 CFU/ml menjadi 17,6 x 105 CFU/ml. Hasil perhitungan estimasi karbon ini diharapkan dapat berfungsi sebagai dasar untuk menghitung estimasi karbon dalam Vegetasi Hutan Jati dalam Skala Nasional.
The plant nursery is an important cultivation phase to improve the quality of cocoa. However, the conventional nursery container namely polybag has the potential risk to contaminate the environment if the waste is wrongfully handled. A biodegradable pot (BioPot) is a satisfactory alternative nursery container considering its plantable and degradable characteristics. This study aimed to investigate the effect of BioPot compositions and size to support the growth of cocoa (Theobroma cacao L.) seedling as polybag substitution. This research was conducted using a randomized complete design with 1 control (polybag) and 15 treatments combination. The treatments consisted of 5 BioPot compositions (percentage of water hyacinth and banana pseudostem range from 30-70%) and 3 BioPot size (width 5,5 cm and length range from 10.5-11.5 cm). The seedling growth data were analyzed using ANOVA then by means using HSD (Tukey test) and Dunnet test at a 5%. The results showed that the several BioPot compositions and size produced equal seedling quality to polybag and not statistically different based on seedling growth variables. This finding confirmed that the all tested BioPot compositions and size in this study, customized and adjusted according to the raw aterials availability, can be used as polybag substitutes for cocoa nurseries. The implication of this study is the use of BioPot for seedling container that support environmentally sustainable agriculture especially in plant nurseries.
