Abstract

Economic valuation is a method for revealing the importance of a forest based on monetary value. The economic valuation of the Pesanggrahan Forest is carried out to reveal the economic value of Direct Use Value, Indirect Use Value, Option Value, Existence Value, and Bequest Value to obtain the Total Economic Value (TEV) of the Pesanggrahan Forest area. The methods used to determine the economic value are Market Price, Replacement Method, and Contingent Valuation Method. The results show that Pesanggrahan Forest have a Total Economic Value IDR. 268,962,582,306. This total value is the value of the protected forest IDR. 145,753,885 and production forest IDR 123,209,166,421. This value describes the magnitude of the benefits of forest as an economic and ecological function in the Pesanggrahan Forest Area, Malang Regency. Protected forest have greater economic value than production forest, so it is hoped that forest conversion will not occur again, both in the Pesanggrahan Forest and other forest in Indonesia.

Abstract

Ultisol faces several challenges as agricultural land, including high soil acidity, low organic matter content, macro-nutrient deficiencies, and low cation exchange capacity that need to be addressed. One proposed solution is the use of oil palm empty fruit bunch (EFB/TKKS) compost, which is rich in N, K, and organic C. This compost can improve the physical properties and soil structure, making it a potential alternative for amending Ultisol. Pakchoi, a vegetable rich in vitamins and minerals, has broader stems and leaves compared to regular green mustard. It thrives in various conditions, both lowland and highland, and has a substantial market demand. This research aims to assess the impact of EFB/TKKS compost application on the growth and yield of pakchoi in Ultisol and to determine the optimal dosage. The study employs a Completely Randomized Design (CRD) with one factor, consisting of 5 treatments and 4 replications, totaling 20 experimental units. The treatments include t0 = TKKS compost 0 ton ha-1, t1 = TKKS compost 15 ton ha-1, t2 = TKKS compost 20 ton ha-1, t3 = TKKS compost 25 ton ha-1, and t4 = TKKS compost 30 ton ha-1. The results indicate that the application of TKKS compost significantly influences the growth and yield of pakchoi in Ultisol, with the optimal dosage identified at 20 ton ha-1.

Abstract

This study aimed to find out the effect of shade and manure doses on the growth and production of Neptunia oleracea. The research was designed using factorial completely randomized design (2x3). There were two factors, the first factor was shade, namely without shade and 75%-net shade, while the second factor was the dose of manure, namely 0, 10, and 20 grams/polybag, respectively. Each treatment had five replications. The result showed that shade significantly (P<0,01) inhibits the number of petioles, number of root nodules, and yield production of Neptunia oleracea but does not affect plant height and the number of branches. Manure dosage had not significantly affected productivity of N. oleracea. There was no interaction between shade treatment and manure dosage. It concluded that Neptunia oleracea as a forage is more productive when grown up without shade.

Abstract

This study examines the integration of oil palm and cattle farming in South Kalimantan, Indonesia, to support meat production for the new capital city. Kotabaru, a district with abundant oil palm plantations, faces a challenge in meeting the increasing demand for beef. This research analyzes the distribution of superior livestock, develops an oil palm-cattle integration model, and formulates development strategies. The study uses location quotient (LQ), localization index (LI), and specialization index (SI) analysis, field observations, interviews with farmers and stakeholders, and SWOT analysis. Conducted in four sub-districts of Kotabaru over eight months, the research identifies superior cattle base areas and proposes three development models: intensive, semi-intensive, and extensive. The SWOT analysis generates short-term and medium-term strategies for developing oil palm-cattle integration.

Abstract

The objective of this study was to determine the nutritional content of black soldier fly (BSF) maggot meal after undergoing steaming and roasting processes. Steaming was aimed at reducing the crude fat content in the maggot meal, while roasting was intended to accelerate the drying process of fresh maggots. The maggots used in this study were 28-day-old maggots fed with quail manure. The research method employed was an experimental method using a Completely Randomized Design (CRD), consisting of 4 treatments and four replications. The treatments given were: A (maggots not steamed and not roasted), B (maggots not steamed and roasted), C (maggots steamed and not roasted), and D (maggots steamed and roasted). Parameters analyzed included dry matter (%), ash content (%), crude protein (%), and crude fat (%). The results of variance analysis showed that the processing had a very significant effect (P<0.01) on the dry matter, ash content, crude protein, and crude fat content of the resulting maggot meal. The conclusion of this study is that the combined application of steaming and roasting significantly reduced the fat content in maggot meal by up to 87% and increased the protein content by 4%. This processing technique resulted in a product with enhanced quality, extended shelf life, and broader application potential in the feed industry.
